26、packages are, at present, selected and compared at a rated condition. This condition does not represent the usual operating conditions of the equipment over a season. This operating condition can be better assessed by comparing equipment at representative reduced capacities and determining the Seaso

27、nal Energy Efficiency Ratio and Seasonal Coefficient of Performance. Fixed capacity heat pumps, air conditioners and liquid chilling packages deal with varying loads by varying the operation time. The efficiency of the system is dependent on the effectiveness of the controlling thermostats. Variable

28、 capacity air conditioners, liquid chilling packages and heat pumps, by continuous or step control of the compressor, can more closely match the varying load improving system efficiency. This European Standard provides part load conditions and calculation methods for calculating the Seasonal Energy

29、Efficiency Ratio (SEERon) and Seasonal Coefficient of Performance (SCOPon and SCOPnet) of such units when they are used to fulfil the cooling and heating demands. Other energy consumptions can occur when the unit is not used to fulfil the cooling and heating demands such as those from a crankcase he

30、ater or when the unit is on standby. These consumptions are considered in the calculation methods for reference SEER and reference SCOP. Reference SEER/SEERon and reference SCOP/SCOPon/SCOPnet calculations may be based on calculated or tested values. In case of tested values, this European Standard

31、gives the methods for testing heat pumps, air conditioners and liquid chilling packages at part load conditions. The rating conditions and test methods of units operating at rated and application capacities are given in EN 14511-2 and EN 14511-3. The methods for calculation of system energy efficien

32、cies for specific heat pump systems in buildings are given in EN 15316-4-2.

33、ean Standard covers air conditioners, heat pumps and liquid chilling packages. It applies to factory made units defined in EN 14511-1, except single duct, control cabinet and close control units. This European Standard gives the calculation methods for the determination of reference seasonal energy

34、efficiency SEER and SEERon and reference seasonal coefficient of performance SCOP, SCOPon and SCOPnet. Such calculation methods may be based on calculated or measured values. In case of measured values, this European Standard covers the test methods for determination of capacities, EER and COP value

35、s during active mode at part load conditions. It also covers test methods for electric power consumption during thermostat-off mode, standby mode, off-mode and crankcase heater mode. This European Standard serves as an input for the calculation of the system energy efficiency in heating mode of spec
