Energy managers ecoSMART

The ecoSMART energy managers, combined with our own control strategies and software, convert our entire range of heat pumps into SG (smart grid) ready products.

Thanks to the great versatility provided by the high level of control, the modular capacity of Ecoforest heat pumps, the possibility of communication and finally the data transmission between the controllers, we’ve been able to design our own strategies.

The ecoSMART energy managers allow thermal and electrical storage in addition to other functionalities. This technology is unique in Europe, being currently patented, controlling in the most efficient way the excess energy generated by your installation and the heat pump.

ZERO BALANCE BETWEEN PRODUCTION AND CONSUMPTION
Energy managers intelligently adjust if there is a surplus of energy in the system. Through a communications bus, the existence of any surplus is communicated to the heat pump, which then changes its consumption to take advantage of the surplus.

TARIFF CONTROL
The energy managers allow users to establish schedules of the high and low electricity rates for the summer and winter periods. The heat pump will consume more energy when electricity is cheaper and reduce consumption when it is more expensive.

POWER LIMITATION

MANAGEMENT OF NON-CRITICAL LOADS

It’s also possible to limit the power consumed by the installation with the heat pump. If the consumption level is close to the set limit, the heat pump will reduce its power consumption, so as not to exceed it.

The energy managers allow relay outputs to feed up to five non-critical loads. These charges will only be activated in case of electrical surplus, the power and time are configurable. The deactivation of the same can be done by changing the level of consumption of the electrical network, through a timer or manually

Description of the system

The e-domus project is a new exclusive residential complex of 63 single-family houses, each with 3 or 4 bedrooms, and around 280 m², all located in the “La Cárcava” sector of Boadilla del Monte.
Avant-garde architecture in a gated and private community, equipped with a swimming pools, paddle tennis courts, recreation areas and landscaped spaces make this area quite desirable.
Heating, cooling and DHW all provided by a ground source collection array and distributed through underfloor heating with a non-polluting system of high energy efficiency and low consumption.

The aproximate surface area to be heated in each of the homes is around 194 m2. Each with energy demands of 10.47 kW in heating and 8.38 kW in cooling.
The geothermal collection field of each of the homes consists of 170 ml distributed in two 85.00 ml probes equipped with a 40 mm REHAU PE-RC simple probe.
The installed heat pump is an ecoGEO C4 3-12 HTR, capable of producing heating, passive and active cooling as well as domestic hot water at high temperatures.

Performances registered

Ecoforest heat pumps allow the user to monitor both the monthly and annual values of power, energy collected, energy produced, as well as the electrical consumption of the system. In addition to this, thanks to the Easynet tool they can be consulted remotely through any device with an Internet connection. Next, the simply spectacular results obtained after the installation of the heat pumps are presented, thanks among other things to our exclusive HTR technology that allows the simultaneous production of heating / cooling and DHW / pool.

However, thanks to the HTR technology, this energy extracted from the home is used and reused for the either production of DHW or for the heating of a pool simultaneously, (figure 2) thus achieving previously unattainable levels of performance for any heat pump with conventional technology.
Furthermore, all this increases both the life of the heat pump and comfort in the home as a result of the consequent reduction in the number of cycle investments.

Traditional heat pumps waste all the energy extracted from the house in the cooling process, transferring it to the ground (ground source) or to the ambient air (aerotermia) (figure 1).

Bath Abbey
As part of the Abbey`s Footprint project, sections of the medieval church have been closed off to the public since May 2018 for essential repairs and restoration work to save the Abbey floor from collapse. At the same time, the historic floor is also being fitted throughout with an eco-friendly underfloor heating system that will eventually be fuelled using renewable energy generated by Bath’s thermal water.
Every day, a quarter of a million gallons of hot water flow through the Roman Baths from the thermal spring located at the heart of the site. A large quantity of this hot water eventually ends up in the nearby River Avon via the Great Roman Drain. When harnessed and converted, it could potentially produce 1.5 megawatts of continuous energy to support a 200kW ground source heat pump system.

Description of the system

The project is understood to be the first of its kind as it will source its energy for the ground source heat pump from the water that flows out of the Roman Baths in the centre of Bath.
Every day 1.1 million litres of hot water at approximately 37 degrees flows through the Roman Baths from underground springs. Most of it travels straight past the Abbey and into the river via a subterranean Roman drain.
The Abbey uses two 25-100kW HP ecGEO heatpumps

The heatpumps use “energy blades” to collect heat form the sub terranean water.
All the pipework and fittings and EnergyBlades that are installed in the Great Drain are made from stainless steel to give the best protection against the harsh environment down there.
The blades used at Bath abbey were custom made due to restrictions in space, but also because of the high levels of temperature and corrosive elements.

Background

Description of the system

Ecoforest was founded in 1959 by José Carlos Alonso; His vision was to develop innovative products that are both economical and respectful of the environment, with the intention of making the world a better place.
Today, more than 50 years later, Ecoforest is the technological leader in the heating sector, with solutions based solely on clean and natural energy.
Thanks to the company’s national and international growth in recent years, Ecoforest has again been forced to expand its facilities. This new building is a prime example of integration of several different technologies, sustainability and energy efficiency.
30 www.ecoforest.com

The energy system used in the Ecoforest heatquarters is unique for several reasons. We start with the catchment system, the heatpumps use the building’s huge water tank as a system for capturing heat. The tank is around 700,000L, the temperature of the cistern is around 15ºC all year round.
Additionally, the energy manager used (ecoSMART e-manager) connects the heat pumps to eachother, but also with the photovoltaic panels on the roof. Any surplus generated by the 80 kW pv installation gets used by the heatpumps to generate free energy, instead of being sent back to the grid for deminished reward.
With just two compact machines, we are able to provide heating cooling, DHW and climate control for the office, factory and laboratory (over 14,000m² in total). The factory also has special ventilation/airconditioning system, which runs free of charge when there is surplus from the photovoltaic panels.

Collection systems

The ecoGEO heat pumps are compatible with many different capture systems. Although traditionally associated with horizontal or vertical ground source intake, most systems can be used as an energy source for heat pumps.
The ecoGEO heat pumps have the added benefit of also being able to use aerothermal capture systems, using the AU air heaters available in sizes 12kW, 40kW, 70kW and 150kW. The ability to use airsource as a capture system also offers the possibility of combining both technologies, hybridizing the geothermal and aerothermal intake depending on the performance and the temperatures of each collection system.

This installation at our HQ captures the energy directly from the cistern built to supply the fire-fighting installation, this cistern has a capacity of 730,000 liters, enough to supply the energy required to heat the building. This has saved a significant amount of money, eliminating the need for both wells boreholes, which were a mandatory feature when constructing in the area.
Finally, other types of special catchments that are also compatible or commonly used with ecoGEO heat pumps Energy Blades, (widely used in the UK), and thermoactive piles or Baskets, (especially interesting in Germany)

As mentioned previously, phreatic catchment can also be used, taking advantage of the water resources that usualy maintain temperature year round. The main benefit of using this type of capture is the economic savings gained by not having to assume the costs of drilling.

Below is a detailed description of the ground source system, which uses dynamic closed loop probes (DCL). The system was installed by Itecon SL at the Hotel Voramar located in the town of Benicassim (Castellón).
Description of the system
A cascading system was set up with a DCL ground source probe, which was connected to an evaporation / condensation circuit and two reversible ground source heat pumps. These provided heating, DHW and active cooling ( positive/negative) for the entire hotel.
The system consists of: – 5 boreholes for ground source, surounding the perimeter of the building – 5 DCL ground source probes placed in the 5 boreholes joined by

intake circuit conduits and electrical power lines, with controls and sensors in standardized trenches, leading to technical plant room. – Two ecoGEO HP3 water-water heat pumps, ground source collection, with 100kW of nominal thermal power each. A total 200 kW for the complete HVAC (Heating, ventilation and Air conditioning) of the building. – Hydraulic manifolds, an impulsion system and thermal fluid management in the technical plant room, all connected to the heat pumps and the ground array capture system. – Integration of existing solar thermal system in facilities, with integral management of thermal energy and programming of its use in ACS. – Control and monitoring system for thermal production facilities with total integration of the different subsystems.
Amazingly all this has been installed into the technical room of a new plant annexed to the building, including electrical power systems, electrical protection, ventilation, lighting and technical room security.

Annual consumption

The system has consumed approximately 3,290 worth of electricity, and has produced 155,206kWh of thermal energy. During this time in 2017, the price of energy was around 0,021 per kW.h.
A system of equivalent size, using AC’s and diesel boilers (like the one that was replaced by the ground source heat pump) would have an annual consumption (with a lower calorific value of diesel of 9.98kW · h / liter and an EER for chillers of qualification C 2.1) of:
· Electricity: 40,672 kW · h
· Diesel fuel: 8,685 liters

The total cost would be 5,084 in electricity and 7,382 in diesel.
An annual saving of 9,176 euros, not counting the savings in maintenance or other factors.
There is an annual reduction of greenhouse gas emissions (According to values of emission factors of the IDAE) equivalent to 21,556kg of CO2.
The renewable system saves CO2 emissions equivalent to planting 10,000m² of pine trees, approximately 1,600 trees or annual emissions of 30 cars.

The energy manager, e-source
The ecoSMART e-source source manager is an electronic controler designed to manage several sources of energy simultaneously.
It can work with a single ecoGEO HP heat pump or with a cascade of several HP ecoGEO heat pumps controlled by a supervisor ecoSMART. To do this, you must establish pLAN bus communication with the heat pump or the heat pump cascade.
E-source functionalities include:
– Management of up to four independent collection sources – Management of defrosting of aerothermal sources
Advantages of e-source:
– Reduction of costs associated with drilling – Possibility to utilize hybrid installations – Opens up possibilities where drilling limitations have previously prevented new installations – Defrosting aerothermal sources (without stopping the compressor). – All the advantages of ecoGEO HP geothermal pumps with aerothermal source
With e-source, combining different capture systems to create unique installations is simple and effective. Furthermore, with access to the Internet through the Easynet and the Supervisor (cascade manager), the e-source can create some of the most versatile installations on the market.

The advantages of Ecoforest technology

Right from the start, Ecoforest understood that ground source heat pumps were the future of the heating & cooling industry. For this reason, we strove to modernize and innovate wherever we could. We were the first manufacturer of ground source heat pumps to include both inverter compressors and active cooling cycle inversion in the
INVERTER TECHNOLOGY and ECOFOREST SOFTWARE:

The R&D team at Ecoforest is constantly developing new and effective software for all the machines we produce, developing specially designed controls for our entire range of heat pumps. Thanks to these constant improvements, ecoGEO heat pumps are able to modulate the power from 25% to 100% providing unsurpassed performance and making our heat pumps the best in the market.

Some of the additional advantages ecoforest heatpumps have over traditional heat pumps include: – More compact and economic facilities. – Less electrical consumption. – Greater durability and reliability.

DANFOSS SCROLL COMPRESSOR

ACTIVE COOLING BY INVERSION THE CYCLE:

Specially designed to utalize the inverter technology, ecoGEO heat pumps incorporate a modulating Scroll compressor, which offers several advantages over traditional rotary compressors such as a longer life, higher efficiency and a lower noise level.
CASCADE UP TO 600 kW
With the ecoGEO’s, it’s not only possible to cascade up to 600kW, but also micromanage the entire system, following the efficiency of each individual unit, and allowing them to modulate at all times, so as to maximise efficiency. Allowing the user to distribute the workload as they see fit.
56 www.ecoforest.com

The incorporation of the 4-way valve allows heating and cooling to be carried out with the same equipment, negating the need to install any additional external modules. External modules can often reduce efficiency, increase the cost of installation and the cost of maintenance.
In addition to this, our extensive experience in the production of cooling, which is in many ways more difficult than the production of heating, has allowed us to develop one of thet the safest and most reliable heat pumps on the market.
One example of a way we have improved the safety is by adding antifreeze protection on the exchangers, for security against condensation on the circuits.

Another company which we collaborated with on the A Granxa project is ACELEC Instalaciones Eléctricas S.L. ACELEC was in charge of replacing and reforming electrical controls, protection panels, power supply lines and control of the equipment that make up the installation.
Thanks to the installed monitoring system, both the temperature of the circulating pumps from the boreholes and production can be seen at any moment, in flow and in return. The same is possible with the temperatures and pressures of the compressor, obtaining information at any moment from the values both for aspiration and discharge of the same.

Finally, the hours of operation for heating, cooling and the electrical consumption derived from heat pumps through the same application can also be measured.
The results have been nothing short of spectacular. After the installation of the ecoGEO heat pumps, the electric bill has been reduced by over half, and in addition to heating, the cooling which was previously carried out by a dedicated chiller is now also done by the heatpumps, saving even more money and energy. The current SPF (Seasonal Performance Factor) of the installation since the opening of the installation is 5.55.

PROJECTS REFERENCE
Zugligeti Lóvasút

The Zugligeti Lóvasút building is a gorgeous establistment rich with history situated in the heart of Hungary. The building is a reconstruction of the old railway station in Zugliget, which was the final train station for horses in Hungary. The structure was refurbished in 2016 with the support of the Hungarian government, the EGF, and the Hegyvidéki Önkormányzat. It was reopened to the public on 17th of September 2017.
The company Smartcool Kft, who are the official distributor of Ecoforest in Hungary, carried out the entire HVAC project.
However, Geoconcept also deserves credit as the company in charge of carrying out the system of capture of the heat pumps.

Background

Description of the system

The construction of this building dates back to the late nineteenth century, initially it was a railway station on horseback (the final ever built in Hungary). Later howeverit would end up becoming a simple stop, that included general services such as a post office. Finally, in 1977 it was abandoned and fell into dilapidation.
Finally after several failed attempts, a reconstruction project was approved and the building saw new life as museum with a cafeteria and restaurant.

The ecoGEO HP1 ground source heat pump is used for the production of domestic hot water and heating, while the ecoGEO HP3 is also used for cooling.
A passive cooling exchanger was installed, which is managed by the ecoGEO HP1 12-40 heat pump to cool the collection area and recover the energy from the boreholes during the summer. In this way it could be said that active cooling and passive cooling are being produced simultaneously. This is possible thanks to the technology of Ecoforest heat pumps that allow great versatility.

Description of the system
To provide a full service to this building, two high power Ecoforest ground source heat pumps were installed: – ecoGEO HP1 12-40 kW and ecoGEO HP 3 15-70 kW.

The catchment is a ground source system consisting of a total of 24 boreholes made by vertical drilling. Due to the location and the terrain, the maximum extension of these boreholes is 80 meters each, which means a total of 1920 meters drilled around the surface of the building.
The system is a perfect example of high end refurbishment with a strong commitment to the environment. High yields and a zeo visual impact are achieved to the benefit of everyone.

Why use heat pumps with Inverter?
In traditional heat pumps (ON-OFF) the Seasonal Performance Coefficient (SPF) decreases significantly because the heat pump can not adapt to variations in demand, and the heat pump drive temperature needs to be higher .
– It is impossible to set the outlet temperature (the higher the inlet temperature, the higher the exit temperature) -> Buffer Tank -> Lower efficiency (maximum COP only in the lower part).
– It is necessary to install a buffer tank and at least one additional shunt group, which considerably increases the cost and complexity of the installation.
– In addition, the buffer tanks represents a loss of efficiency throughout the year, since it has energy losses exchanging into the environment.

SAVINGS

With inverter technology, energy savings of up to 40% can be achieved, depending on usage, by regulating the operating frequency of the compressor.

MORE SILENT
By avoiding continuous ON / OFF starts, the compressor and fan operate at low speeds, considerably reducing the noise level.

ENERGY EFFICIENCY
Adaptation to consumption always within the comfort range.

DURABILITY
By avoiding the continuous ON / OFF starts, the device has to make less effort therefore, it will extend its life considerably.

COMFORT
The temperature remains stable without sudden changes, which guarantees greater comfort. Increased comfort in the underfloor heating when working with a temperature jump.

Wimpole Hall, a National Trust installation

WIMPOLE HALL PROJECT
National Trust installation

PROJECTS REFERENCE
Wimpole Hall

National Trust chose ISOenergy for the difficult task of modernizing the heating systems of the Wimpole Hall building.
The large seasonal changes, combined with the large surface areas and the general lack of insulation make heating a building of these characteristics very complicated. In the past, the solution has been simply to use large amounts of fuel to maintain the interior temperature. However, due to the increase in the price of oil and the need to be more respectful of the environment, National Trust decided that it was time for a change.
ISOenergy chose Ecoforest heat pumps for this purpose, thanks to the success accumulated in other facilities.

Background

Description of the system

Wimpole Hall is the largest building in Cambridgeshire, England and consists of a main mansion and several annex buildings.
The main mansion was built in 1640 and was originally owned by the Chicheley family. Throughout the centuries, it was a busy place, with numerous dinners and events that were attended by Queen Victoria.

Because of the large scale of this job, the national trust actually required two different installations, first a cascade of two ecoGEO heat pumps 15-70kW which were installed in the main mansion.
Aditionally an installation was made in the restaurant attached to this building. In this case an ecoGEO HP1 of 12-40 kW, accumulating a total of 180 kW in the installation of Wimpole Hall and its annexes.

In 1976, a National Trust building was demoted, after the transfer by Mrs. Elsie Bambridge before her death. It is currently a space open to the public where events and visits are held.

The collection system used for this installation is made up of a total of 30 geothermal wells of 125 meters each, located in the parking area.

Eimos School

The new pre-school located in Mos uses geometry and natural occouring themes to encompasses all its students. The long fragmented roof strips allow light to pour in the south side, providing the building with an abundance of natural light in all interior spaces.
Well lit and ventilated, it’s a building in which children can enjoy nature protected by the outer circle and completely disconnected from the industrial estate.
All the classrooms are oriented to the South and have direct access to the outdoor leisure area.
The project was led by Estefanía Grandal (Encaixe Arquitectura y Ingeniería), Faustino Patiño and Juan Prieto.
The work has been executed by the construction company Misturas, for the network of infant schools of the Xunta de Galicia, Galiña Azul.

Background

Description of the system

To continue the nature trend, the facilities will use renewable energy generation systems as well as passive architecture concepts, trying to adapt the design of the building to sustainability standards. The project aims to create a quality interior space in which students and teachers can develop and enjoy the learning process, a fundamental activity at such an early age.
The nursery school has 82 places divided into 6 classrooms for ages 0-1, 1-2 and 2-3.

The total surface area which needed to be heated was 550 m2, with energy demands of 15 kW in heating.
The heat is captured by an Ecoforest AU12 air heater, which has been placed within the schools walls, in order to avoid distrupting the visual symmetry.
The installed heat pump is an ecoGEO B2T 5-22 EH, capable of producing heating and domestic hot water at high temperatures.
In addition, the team manages legionella control and DHW recirculation.

Performance returns

Ecoforest heat pumps allow the user to monitor both the monthly and annual values of power, along with the amount of energy captured and produced. The electrical consumption of the system are also recorded in it.
The defrosting technique for the ecoGEO is both unique and efficient (figure 2): the compressor stops during the defrost cycle, the energy source is selected for the defrost cycle (either from heating, DHW or pool) and through an internal heat exchanger (A) the defrost is a completely hydraulic cycle. This has the effect of considerably increasing of the seasonal performance (SPF), reduces the power consumption and significantly reducing the defrostingtime.

Becuase the compressor does not have to invest energy into reversing its cycle (like the current technology, figure 1), both lifespan of the heat pump and the comfort in the home are increased as a consequence of the reduction in the number of cycle investments.
All this means that with the modulation of the ecoGEO, December (one of the coldest months together with January and February in this region) has a monthly SPF of more than 5, as can be seen on the next page.

Background

Description of the system

Finner Camp, a military installation near Ballyshannon in Ireland. The barracks, which were built on a site known for its megalithic tombs, were completed in 1890. Following the Anglo-Irish Treaty, the barracks were handed over to Irish Free State forces in 1922. In World War II, it was close to the Donegal Corridor. In August 1969 there was false speculation in the media that Taoiseach Jack Lynch would use the barracks to launch an invasion of Northern Ireland in order to protect the Catholic community there. The barracks are now home to the 28th Infantry Battalion, Irish Army.

Each barracks is HVAC with an ecoAIR EVI 4-20 kW heat pump as outdoor unit and a CM indoor unit. Each barrack have a 500 litres DHW tankdue to the high DHW demands.
The emission system has also been upgraded to underfloor heating to make the most efficient combination and to obtain large savings throughout the year.

These barracks have been used to upgrade the heating system of the Donega military barracks which had an LPG boiler installation with copper hot water tanks of about 180 litres in each barracks.

Description of the system

The housing cooperative Scaya Alcorcón Sociedad established requirements for high energy efficiency and savings for the HVAC system and production of hot water from the 42 Single Family Homes in the municipality of Alcorcón in Madrid.
The housing project consists of 42 attached single-family homes, there are five types, differentiated by size and distribution. Each of them has two habitable floors and a garage floor (below ground level). The homes have an area of between 68m2 and 150m2 with underfloor heating on two floors (ground floor and first floor). The total heated area is 4,566m2.

To extract the necessary heat from the ground, 30 vertical boreholes of 135 meters of depth each were dug. The collection system has a total length of 4,050 meters.
The installation comprises of 3 cascading water-water heat pumps. For this reason Ecoforest inverter model ecoGEO HP3 with a power range of 15-70 kW where chosen, because of their excellent modular capabilities.
The peak energy demand will be in heating mode, calculated at 205,000 W . The DHW storage tank is 3,000 l (2 Units) and the inertial tank is only 500 l.

The dispersion of heating and cooling will be through the radiantcooling floor. Each house has a chronothermostat in the room that will act on a zone valve at the entrance of each dwelling, the rest of the rooms will have an electronic room thermostats installed.
The control of the energy consumption of air conditioning is done by means of energy meters that are installed at the entrance of each dwelling and reports the consumption data to the community administrator.
The control of domestic hot water consumption is through individual volumetric meters located in the same location.
