complete package, except for liquid chilling packages with remote condenser. This standard is primarily intended for water and brine chilling packages but can be used for other liquid subject to agreement. This standard applies to air-to-air air conditioners which evaporate the condensate on the condenser side. The units having their condenser cooled by air and by the evaporation of external additional water are not covered by this standard. This standard does not apply to units using transcritical cycles, e.g. with CO2 as refrigerant. Installations used for heating and/or cooling of industrial processes are not within the scope of this standard. NOTE 1 Part load testing of units is dealt with in CEN/TS 14825. NOTE 2 All the symbols given in this text should be used regardless of the language used. 2 Terms and definitions For the purposes of this European Standard, the following terms and definitions apply. 2.1 air conditioner encased assembly or assemblies designed as a unit to provide delivery of conditioned air to an enclosed space (room for instance) or zone. It includes an electrically operated refrigeration system for cooling and possibly dehumidifying the air. It can have means for heating, circulating, cleaning and humidifying the air. If the unit provides heating by reversing the refrigerating cycle then it is a heat pump EN 14511-1:2004 (E) 5 2.2 heat pump encased assembly or assemblies designed as a unit to provide delivery of heat. It includes an electrically operated refrigeration system for heating. It can have means for cooling, circulating, cleaning and dehumidifying the air. The cooling is by means of reversing the refrigerating cycle 2.3 comfort air conditioner or heat pump air conditioner or heat pump to satisfy the requirements of the occupants of the air conditioned room 2.4 close control air conditioner air conditioner to satisfy the requirements of the process carried out in the air conditioned room 2.5 control cabinet air conditioner air conditioner to satisfy the requirements of the control cabinet 2.6 packaged unit factory assembly of components of refrigeration system fixed on a common mounting to form a discrete unit 2.7 single split unit factory assembly of components of refrigeration system fixed on two mountings or more to form a discrete matched functional unit 2.8 single-duct air conditioner air conditioner for spot cooling in which the condenser intake air is introduced from the space containing the unit and discharged outside this space 2.9 liquid chilling package factory-made unit designed to cool liquid, using an evaporator, a refrigerant compressor, an integral or remote condenser and appropriate controls. It may have means for heating which can be reversing the refrigerating cycle, like a heat pump 2.10 heat recovery liquid chilling package factory-made liquid chilling package designed for the purpose of chilling liquid and recovering of heat (责任编辑：admin) |
