How air source heat pump works

A heat pump is an energy efficient system that absorbs heat from the ambient air for heating and hot water. By using the ambient air and transferring this heat into the house through a hydronic system, such as floor heating, fan coil units and radiators
Compressor Expansion Valve
Condenser
Heat Distribution
Heat Source
Evaporator

Stage One

The heat transfer medium (the refrigerant) is colder than the heat source (the outside air). As the outside air passes across the fi rst heat exchanger (the evaporator) the liquid refrigerant absorbs the heat and evaporates .
1

Stage Two

The vapor passes to the compressor and is compressed. When compressed the pressure is increased and the temperature of the vapor rises, effectively concentrating the heat.
2

Stage Three

The hot vapor passes to the second heat exchanger (the condenser) where the heat is released to the water and the vapor condenses back into a liquid. The water heated in by the Thermal system is circuit to the indoors for central heating and domestic hot water heating.
3

Stage Four

The liquid refrigerant passes through an expansion valve, reducing its pressure and temperature, ready to start the next circuit.

Mono outdoor unit Mono outdoor unit absorbs heat from the outside air and transfers it to the water in the hydronic modular, through water to supply heat to indoor side. Domestic water tank (field supplied) Domestic water tank is used to supply sanitary hot water. The hot water from the Mono unit release heat to water in the tank through the inner coil, and cold water in the tank is heated. Usually there is an addition electric heater in the domestic water tank. User interface Control unit with colorful touchscreen panel controls the heat pump operation, and it can control system with up to two mixing heating/cooling circuits, one direct heating/cooling circuit and DHW preparation (with DHW recirculation pump operation control as well) (mandatory additional equipment). It can be connected to a web portal and mobile application afterwards.

Mono system

Typical Applications
Example: Application 2: Thermal Mono for space heating and domestic hot water Room thermostat is not connected to the Mono unit but to motorized valve. Each room’s temperature is regulated by the motorized valve on every water circuit. Sanitary hot water is delivered by the domestic hot water tank connected to the Mono unit. In this situation, bypass valve is necessary.

Floor heating
Split type outdoor unit The outdoor unit absorbs heat from the outside air and transfers it inside through refrigerant piping. Hydronic box The hydronic box heats the water by refrigerant from outdoor unit. The heated water circulates through heating device such as floor heating, radiators, fan coil units as well as inner coil of domestic hot water tank. Domestic water tank (field supplied) Domestic water tank is used to supply sanitary hot water. The hot water from the hydronic box release heat to water in the tank through the inner coil, and cold water in the tank is heated. Usually there is an addition electric heater in the domestic water tank.
