Condensing units for refrigeration - Rating conditions, tolerances and presentation of manufacturer's performance data

This European Standard specifies the rating conditions, tolerances and presentation of manufacturer's performance data for condensing units for refrigeration with compressors of the positive-displacement type. These include single stage compressors and single and two stage compressors having an integrated means of fluid sub cooling. This is required so that a comparison of different condensing units can be made. The data relate to the refrigerating capacity and power absorbed and include requirements for part-load performance where applicable.

evaporating temperature

arithmetic average of the evaporator inlet temperature and the evaporating dew point temperature of

the refrigerant at the pressure of the condensing unit inlet
Note 1 to entry: For more information, see B.1.

Note 2 to entry: For refrigerants without glide the evaporating temperature is equal to the dew point

temperature at the condensing unit inlet pressure.

Note 3 to entry: For refrigerants with glide the evaporating temperature is the mean of the evaporator inlet

temperature and dew point temperature at the condensing unit inlet pressure with the following assumptions:

isenthalpic expansion from condensing unit outlet temperature to the condensing unit inlet pressure, isobaric

evaporation, no suction line pressure drop, enthalpy, entropy and temperature changes of the refrigerant are

linear with the vapour mass fraction (vapour quality) during evaporation and effects of oil circulation are ignored.
