AWR-HT Air Source Reversible Heat Pumps

Air source reversible heat pump with scroll compressors, from 34 to 181 kW

Committed to achieve premium sustainability and efficiency targets, AWR-HT is the new compact heat pump able to produce high temperature water for domestic use, but also chilled water for air conditioning in Summer.
With this solution the space heating can be easily provided by using radiators, without any major changes on the already existing distribution system.
AWR-HT is a ready-to-use heat pump. Neither probes nor connections pipes to wells are needed, making this heat pump an ideal solution for both new and replacement constructions.
THE PERFECT HEAT PUMP FOR EVERY NEED

| The unit works as a heat pump by exploiting the heat of the air-source air via the finned coil heat exchanger and then heats the water
delivered to the distribution system via a plate heat exchanger.
The unit can supply water up to 65°C, ideal for space heating and residential applications, operating over a wide outdoor air temperature range, ideal for space heating and residential applications.
---|---
| The unit operates as a simple chiller and transfers the excess heat from the inside environment (heat of condensation) to the air via a finned coil heat exchanger.

COMFORT APPLICATIONS

• Commercial premises
• Office buildings
• Hotels and resorts
• Healthcare facilities
• Retail and department stores
• Sports and leisure installations

AWR-HT, the easiest and most efficient way to combine both hot water for space heating and domestic use, as well as air conditioning

**| PREMIUM ´CLASS A’ EFFICIENCY
The full range is available with rating over the Class A.
AWR-HT/CA-E and AWR-HT/LNCA-E ensures premium efficiencies and quietness, making this range the best solution for both residential and light commercial markets.
---|---
| OPERATION DOWN TO -20°C
AWR-HT is the perfect solution in terms of extended operation even in extreme weather conditions. Without using any other heating device, this heat pump operates also in harsh climate areas with outdoor temperatures down to -20°C.
| MODULAR CONFIGURATION
For medium- and high- capacity installations, system capacity can be extended to up to 1000 kW using a modular configuration. This feature allows to manage different thermal loads according to the real demand, treating heating requirements for domestic use differently from heating requirements for space heating, or cooling.
| HOT WATER UP TO 65°C
All units produce hot water up to 65°C for space heating and domestic purposes. Thanks to this solution the space heating can be easily  provided by using radiators, without any major changes on the already existing distribution system available on site.
| RELIABILITY ABOVE ALL
AWR-HT offers maximum operating reliability, thanks to their two main features:
▶ Two independent circuits for all sizes;
▶ An advanced system to prevent formation of ice on the coil, ensuring shorter and more efficient defrost cycles.
| RENEWABLE ENERGY FOR COMMERCIAL INSTALLATIONS**
AW-HT is the ideal solution in replacing old boilers systems where there is the need to retain the existing water distribution plant based on radiators.
This situation is typical in public spaces such as schools, government offices, as well as blocks of buildings for residential use, where it is common practice to have a centralized heating and cooling system.

TECHNOLOGICAL CHOICES

W3000SE CONTROL and USER-FRIENDLY USER INTERFACE
Fully in-house software developed by Mitsubishi Electric Hydronics & IT Cooling Systems.

• 19 supported languages.
• Optional serial cards with the most common protocols are available: Mod Bus, BACnet MS/TP RS485, BACnet Over IP, Echelon Lon works.
• “QUICK MIND” logic: a self-adapting algorithm that activates or deactivates the compressors only when a change in the system load moves the flow temperature out of the setpoint neutral zone.
• Diagnostics: “BLACK BOX” function for saving more than 100 machine variables for a rapid troubleshooting.

Advanced technologies smartly applied to achieve top-level performance levels.

Compact Keyboard

The compact keyboard comes as standard in all units.

• Large LCD display and functional keys.
• Quick and easy parameter consultation and adjustment by means of a multi-level menu with settable display language.

Project
This 5-star resort rises on white sands and refreshing waters of the Aegean. Ikos Olivia boasts spacious rooms, suites and bungalows with flowing green gardens, several swimming pools and a Spa.
Challenge
Ensuring maximum comfort for all guests and making their holidays unforgettable both inside their rooms as well as in common areas like swimming pools and the spa, was a key challenge. For owners, energy efficiency and reliability were also fundamental, in order to reduce running and maintenance costs and to contribute to an outstanding business performance of the hotel.
Solution
To perfectly satisfy the hot water request for swimming pools and for domestic hot water, the heating system is based on 9 air source heat pumps AW HT by Climaveneta. These units in fact can supply hot water up to 65°C.
Climaveneta branded heat pumps are ready-to-be-installed units. Neither probes nor connection pipes to wells are needed, thus making the installation activities onsite quick and easy.
Every project is characterized by different needs and system specifications for various climates. All these projects share high energy efficiency, maximum integration, and total reliability resulting from the Climaveneta brand experience.
