23、oners, air/air and water/air heat pumps with electrically driven compressors as well as the properties of the units when used in cooling mode. When these units are used in heating mode by reversing the refrigerating cycle, then prEN 255-1 applies. This standard applies to factory-made units which ca
24、n be ducted. In the case of units consisting of several parts, the standard applies only to those designed and supplied as a complete package. Units having two or more indoor sections connected to a single outdoor unit (multiple split system air conditioners or heat pumps) are excluded from this sta
25、ndard. This standard does not apply to continuously variable capacity control units. This standard does not apply to liquid chilling packages units. A diagram which illustrates the various air flows is included in annex A which forms part of this standard. NOTE. All the symbols given in this text sh
26、ould be used regardless of the language used. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated
27、references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references, the latest edition of the publication referred to applies. EN 255-1Air conditioners, liquid chilling packages
28、and heat pumps with electrically driven compressors Heating mode Part 1: Terms, definitions and designations 3 Definitions For the purposes of this standard, the following definitions apply. 3.1 air conditioner Encased assembly or assemblies designed as a unit to provide delivery of conditioned air
29、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. The heating can be by means of reversing the refrigerating cycle,
30、like a heat pump, see EN 255-1. 3.2 comfort air conditioner or heat pump Air conditioner or heat pump to satisfy the requirements of the occupants of the air conditioned room. 3.3 close control air conditioner Air conditioner to satisfy the requirements of the process carried out in the air conditio
31、ned room. 3.4 control cabinet air conditioner Air conditioner to satisfy the requirements of the control cabinet. 3.5 single packaged unit Factory assembly of components of refrigeration system fixed on a common mounting to form a discrete unit. 3.6 split packaged unit Factory assembly of components
32、 of refrigeration system fixed on two mountings or more to form a discrete matched functional unit. 3.7 spot air conditioner Air conditioner that cools a zone within a space. The condenser intake air is introduced from that space and discharged back into the same space. 3.8 single-duct air condition
33、er An air conditioner for comfort cooling in which the condenser intake air is introduced from the conditioned space and discharged outside this space. 3.9 evaporator Heat exchanger assembly which is designed to remove heat from air of the conditioned space by evaporation of a refrigerant. NOTE. In
34、the case of a heat pump operating in the cooling mode, this will be the indoor heat exchanger, see prEN 255-1. 3.10 condenser Heat exchanger assembly which is designed to transfer heat to the outdoor ambient environment, or any other available source by condensation of a refrigerant. NOTE. In the ca
35、se of a heat pump operating in the cooling mode, this will be the outdoor air exchanger, see prEN 255-1. 3.11 ventilation air Air introduced to the conditioned space through the unit from the outside (see annex A). 3.12 exhaust air Air from the conditioned space through the unit to the outdoor side
36、(see annex A). 3.13 internal leakage air Air interchanged between the indoor side and outdoor side through the unit, but not through the openings designated for this purpose (see annex A). 3.14 total cooling energy (QC) Heat removed by the unit from air within a defined interval of time.

NOTE. This quantity is not used for spot air conditioners because it is not s
38、ignificant. Performances of these devices are expressed in terms of flow-rate and dry bulb temperature. 3.16 latent cooling capacity (PL) Capacity of the unit for removing latent heat from the evaporator intake air. 3.17 sensible cooling capacity (PS) Capacity of the unit for removing sensible heat
39、from the evaporator intake air. 3.18 effective power input (PE) Average electrical power input of the unit within the defined interval of time obtained from: the power input for operation of the compressor, excluding additional electrical heating devices; the power input of all control and safety de
40、vices of the unit; and the proportional power input of the conveying devices (e.g. fan, pumps) for ensuring the transport of the heat transfer media (see 3.23) inside the unit. 3.19 total power input (PT) Power input of all components of the unit as delivered. 3.20 energy efficiency ratio (EER) Rati
41、o of the total cooling capacity to the effective power input of the unit. 3.21 sensible heat ratio (SHR) Ratio of the sensible cooling capacity to the total cooling capacity. 3.22 operating range Range of operation of the unit indicated by the manufacturer and limited by the upper and lower limits o
42、f use (e.g. temperatures, air humidity, voltage) within which the unit is deemed to be fit for use and has the published properties. 3.23 heat transfer medium Liquid or gas (usually water or air) by means of which heat is transferred to or from the unit. 3.24 nominal conditions Standardized conditio
43、ns provided for the determination of data which are characteristic for the unit, especially cooling capacity, power input, EER, SHR. 3.25 sound power level (LW) Ten times the logarithm to the base 10 of the ratio of the given sound power to the reference sound power expressed in decibels. The refere
44、nce sound power is 1 pW (1012W). 4 Designations and denominations 4.1 Designation of temperatures of heat transfer media The designation relating to the temperatures of heat transfer media is formed in such a way that the heat transfer media are indicated together with their temperatures (in degrees
45、 Celsius), the values indicated in the first place referring to the condenser and the values indicated in the second place to the evaporator. All temperatures are inlet temperatures. A short designation is formed in such a way that a characteristic letter is used for the heat transfer medium: A for
46、air and W for water. For example W30/A27 means an inlet temperature of water for the condenser of 30 C and an inlet temperature of air for the evaporator of 27 C. 4.2 Denomination of units The denomination of units normally depends on the heat transfer medium used to remove the heat from the condens
47、er (see table 1). In the case where a unit reverses its refrigerating cycle the denomination can follow the same principles given in EN 255-1. Table 1.
