18、 12/01/2008, Uncontrolled Copy, BSI EN 14511-1:2007 (E) 4 1 Scope This part of EN 14511 specifies the terms and definitions for the rating and performance of air and water cooled air conditioners, liquid chilling packages, air-to-air, water-to-air, air-to-water and water-to-water heat pumps with ele
19、ctrically driven compressors when used for space heating and/or cooling. This European Standard does not specifically apply to heat pumps for sanitary hot water, although certain definitions can be applied to these. This European Standard applies to factory-made units that can be ducted. This standa
20、rd applies to factory-made liquid chilling packages with integral condensers or for use with remote condensers. This standard applies to factory-made units of either fixed capacity or variable capacity by any means. Packaged units, single split and multisplit systems are covered by this standard. Si
21、ngle duct and double duct units are covered by the standard. In the case of units consisting of several parts, this standard applies only to those designed and supplied as a complete package, except for liquid chilling packages with remote condenser. This standard is primarily intended for water and
22、 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 covere
23、d 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
24、 All the symbols given in this text should be used regardless of the language used. 2 Terms and definitions For the purposes of this document, 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
25、 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
