Air conditioners, liquid chilling packages and heat pumps, with electrically driven compressors, for space heating and cooling - Testing and rating at part load conditions and calculation of seasonal performance

active, Most Current
Organization: CEN
Publication Date: 1 December 2018
Status: active
Page Count: 136
ICS Code (Ventilation and air-conditioning systems): 91.140.30
ICS Code (Heat pumps): 27.080
scope:

This document covers air conditioners, heat pumps and liquid chilling packages, including comfort and process chillers. It applies to factory made units defined in EN 14511-1, except single duct, double duct, control cabinet and close control units. It also covers direct exchange-to-water(brine) heat pumps (DXto- water(brine)) as defined in EN 15879-1.

This document also covers hybrid heat pumps as defined in this standard.

This document gives the temperatures and part load conditions and the calculation methods for the determination of seasonal energy efficiency SEER and SEERon, seasonal space cooling energy efficiency ηs,c seasonal coefficient of performance SCOP, SCOPon and SCOPnet, and seasonal space heating energy efficiency ηs,h and seasonal energy performance ratio SEPR.

Such calculation methods can be based on calculated or measured values. In case of measured values, this document covers the test methods for determination of capacities, EER and COP values during active mode at part load conditions. It also covers test methods for power input during thermostat-off mode, standby mode, off-mode and crankcase heater mode.

NOTE 1 The word "unit" is used instead of the full terms of the products.

NOTE 2 The word "cooling" is used to refer to both space cooling and process cooling.

NOTE 3 The word "heating" is used to refer to space heating.
