Division Definitions of heat pumps, air conditioners and comfort chillers

‘heat pump’ means an air heating product:

1. (a)

   of which the outdoor side heat exchanger (evaporator) extracts heat from ambient air, ventilation exhaust air, water, or ground heat sources;

2. (b)

   which has a heat generator that uses a vapour compression cycle or a sorption cycle;

3. (c)

   of which the indoor side heat exchanger (condenser) releases this heat to an air-based heating system;

4. (d)

   which may be equipped with a supplementary heater;

5. (e)

   which may operate in reverse in which case it functions as an air conditioner;

‘air-to-air heat pump’ means a heat pump which has a heat generator that uses a vapour compression cycle driven by an electric motor or internal combustion engine and whereby the outdoor side heat exchanger (evaporator) allows heat transfer from ambient air;

‘water/brine-to-air heat pump’ means a heat pump which has a heat generator that uses a vapour compression cycle driven by an electric motor or internal combustion engine and whereby the outdoor side heat exchanger (evaporator) allows heat transfer from water or brine;

‘rooftop heat pump’ means an air-to-air heat pump, driven by an electric compressor, of which the evaporator, compressor and condenser are integrated into a single package;

‘sorption cycle heat pump’ means a heat pump which has a heat generator that uses a sorption cycle relying on external combustion of fuels and/or supply of heat;

‘multi-split heat pump’ means a heat pump incorporating more than one indoor units, one or more refrigerating circuit, one or more compressors and one or more outdoor units, where the indoor units may or may not be individually controlled;

‘air conditioner’ means a cooling product that provides space cooling and:

1. (a)

   of which the indoor side heat exchanger (evaporator) extracts heat from an air-based cooling system (heat source);

2. (b)

   which has a cold generator that uses a vapour compression cycle or a sorption cycle;

3. (c)

   of which the outdoor side heat exchanger (condenser) releases this heat to ambient air, water or ground heat sink(s) and which may or may not include heat transfer that is based on evaporation of externally added water;

4. (d)

   may operate in reverse in which case it functions as a heat pump;

‘air-to-air air conditioner’ means an air conditioner which has a cold generator that uses a vapour compression cycle driven by an electric motor or internal combustion engine and whereby the outdoor side heat exchanger (condenser) allows heat transfer to air;

‘water/brine-to-air air conditioner’ means an air conditioner which has a cold generator that uses a vapour compression cycle driven by an electric motor or internal combustion engine and whereby the outdoor side heat exchanger (condenser) allows heat transfer to water or brine;

‘rooftop air conditioner’ means an air-to-air air conditioner, driven by an electric compressor, of which the evaporator, compressor and condenser are integrated into a single package;

‘multi-split air conditioner’ means an air conditioner incorporating more than one indoor units, one or more refrigeration circuits, one or more compressors and one or more outdoor units, where the indoor units may or may not be individually controlled;

‘sorption cycle air conditioner’ means an air conditioner which has a cold generator that uses a sorption cycle relying on external combustion of fuels and/or supply of heat;

‘air-to-water comfort chiller’ means a comfort chiller that has a cold generator that uses a vapour compression cycle driven by an electric motor or internal combustion engine and whereby the outdoor side heat exchanger (condenser) allows heat transfer to air, including heat transfer that is based on evaporation into this air of externally added water, provided that the device is also able to function without the use of additional water, using air only;

‘water/brine-to-water comfort chiller’ means a comfort chiller that has a cold generator that uses a vapour compression cycle driven by an electric motor or internal combustion engine and whereby the outdoor side heat exchanger (condenser) allows heat transfer to water or brine, excluding heat transfer that is based on evaporation of externally added water;

‘sorption cycle comfort chiller’ means a comfort chiller which has a cold generator that uses a sorption cycle relying on external combustion of fuels and/or supply of heat.
