BASIC HEAT PUMP OPERATING PRINCIPLE

The Heat Pump contains a sealed and closed-loop refrigerant circuit which contains a mildly flammable refrigerant R-32. When operating, refrigerant is continuously circulated by a compressor where it absorbs heat from the outdoor air which is passed through a heat exchanger and transfers that heat to water which is used in heating and hot water systems.

The circuit consists of four main components/functions.

1. Evaporator Heat Exchanger – Refrigerant absorbs heat energy from the outdoor ambient air.
2. Compressor – Refrigerant is compressed and circulated around the closed loop circuit.
3. Condenser Heat Exchanger – Refrigerant transfers heat energy to the heating or hot water systems.
4. Expansion Device – Refrigerant pressure and temperature is transformed.

BASIC LOGIC AIR FUNCTIONS

• Domestic Hot Water:

  • If there is a domestic hot water (DHW) Cylinder installed and the temperature of the DHW Cylinder is less than the Hot Water setpoint, the primary heat pump circuit is activated and directed (via the divertor valve) to heat the hot DHW Cylinder.
  • The Heat Pump will operate until the DHW Cylinder has reached its setpoint. This function will always take priority over the space heating system within the programmed time.
  • Note: Domestic Hot Water Heating and Space Heating functions cannot operate simultaneously

• Space Heating:

  • If there is a heating demand and the temperature of any thermostat is less than its setpoint, the primary circuit is activated and directed (via the divertor valve) to heat the space heating circuits. The Heat Pump and primary heating circuit circulator will be active until the space heating has reached its setpoint.
  • Note: Domestic Hot Water Heating and Space Heating functions cannot operate simultaneously

• Anti-Legionella:
  If there is a DHW cylinder installed, anti-Legionella measures should be utilized by HSE guidance HSG274 Part 2. The control system is provided with an Anti-Legionella function for the DHW cylinder, the default parameter, which is adjustable according to the installation and user requirements, initiates this function once per week and heats the DHW cylinder to 60°C for 1 hour.

• Logic Air Monobloc ASHP Defrost Method:
  During operation, the Heat Pump will periodically be required to go through an automatic defrosting process depending on the outdoor air temperature and humidity levels. Over time the evaporator will begin to collect water which will then frost. The defrost process causes the accumulated frost to thaw and change to liquid. This liquid water then collects in the base panel and flows through into the condensate drain openings located on the base panel of the Heat Pump. Depending upon the installation type, the water will drain to the ground or a dedicated drainage point.

• Cold Start Function:

  • With the Heat Pump in Standby Mode, if at any time a heating demand is initiated and the primary heating circuit water temperature is below 17oC, then the Heat Pump will not commence operation. At these water temperatures, deterioration of the appliance may be caused upon start-up.
  • The Cold Start Function automatically enables and uses alternative energy sources, dependent upon the installation, to heat the primary heating circuit allowing the heat pump to resume operation.
  • Dependent upon the system configuration the following solutions may provide this function.

• System with DHW Cylinder:
  If there is a DHW cylinder installed, during this event, the Heat Pump circulator pump and DHW cylinder backup heater will operate only to increase the primary circuit water temperature. Once 22 °C is achieved the DHW backup heater will be terminated, and normal Heat Pump operation may then resume.

• No DHW Cylinder:
  If no DHW cylinder is installed, a supplementary backup immersion heater installed within the primary heating circuit must be fitted to provide this function. In this event the supplementary backup heater will operate in the same way detailed above and heat the primary heating circuit water to 22 °C, at which point the supplementary backup heater will be terminated, and normal Heat Pump operation may then resume.

• Combi – Boiler Back Up:
  When using a combustion Combi-Boiler configuration with no DHW cylinder, the boiler will operate to provide this functionality. In this event the boiler will operate in the same way detailed above and heat the primary heating circuit water to 22 °C, at which point the boiler operation will be terminated and normal Heat Pump operation may then resume.

• Frost Protection (Appliance):

  • Note: Only if the appliance is in standby mode and with no DHW or space heating demand.
  • If the outdoor air temperature is ≤ 1°C, Plant Frost Protection will be initiated. During this event, the Heat Pump circulator pump and central heating zone pumps (if applicable) will operate continuously to prevent the primary heating water from freezing.
  • If the outdoor air temperature is ≤ 1 – 5°C, Plant Frost Protection will be initiated. During this event, the Heat Pump circulator pump and central heating zone pumps (if applicable) will operate intermittently to prevent the primary heating water from freezing.

• Frost Protection (Condenser):
  If the primary circuit water temperature is ≤ 4 °C and the Heat Pump has power but is in Standby Mode i.e., no DHW, CH, or Anti-Legionella demand, Condenser Frost Protection will be initiated. Firstly, the Heat Pump circulator pump will initiate, if after a defined period, the primary circuit water temperature is still ≤ 4 °C the backup heater will initiate to raise the temperature to 22 °C. Once this temperature is achieved the backup heater will be terminated and normal Heat Pump operation may then resume. Note: The backup heater utilized in this mode will depend upon the system configuration (refer to Section 2.7.6 Cold Start Function on page 22 for available solutions).

• Frost Protection (Dwelling):
  If the temperature of the dwelling is ≤ 8 °C, the room frost protection mode will be initiated to prevent damage to the central heating system. During this event, the Central Heating zone pumps will be operated intermittently.

• Weather Compensation:

  • Weather compensation regulates and maintains optimum flow temperatures which allows the heat pump to run more efficiently. This function will modulate the water flow temperature relative to the external ambient temperatures. The lower the outdoor air temperature, the higher the flow temperature and vice versa.
  • There are two types of weather compensation available as described below:

• Weather Compensation Alone:
  With this mode selected, the primary flow temperature is calculated based on a heating curve, depending only on the average outside temperature. The weather compensation function is initiated with a permanently enabled outdoor temperature sensor (QAC 34) supplied with the Heat Pump system.

• Combined Weather Compensation & Room Compensation:
  With this mode selected, the primary flow temperature is calculated based on a heating curve and dependent upon the ambient air temperature and the dwelling room temperature. The current room temperature and its variation from the actual setpoint are acquired and considered when controlling the heat pump flow temperature. This way, consideration is given to room temperature deviations, ensuring more accurate room temperature control and optimum efficiency.
