4.5 Test results
4.5.1 Data to be recorded The data to be recorded for the capacity required but is not intended to limit These data shall be the mean values measurement.
4.5.2 Cooling capacity and heat recovery capacity calculation Average cooling and heat recovery capacities shall be determined from the set of cooling and heat recovery capacities recorded over the data collection period. 4.5.3 Heating capacity calculation 4.5.3.1 Steady state capacity test An average heating capacity shall be determined from the set of heating capacities recorded over the data collection period of 35 min. 4.5.3.2 Transient capacity test For equipment where one or more complete cycle occur during the data collection period, the following shall apply. The average heating capacity shall be determined using the integrated capacity and the elapsed time corresponding to the total number of complete cycles that occurred over the data collection period. For equipment where no complete cycle occurs during the data collection period, the following shall apply. The average heating capacity shall be determined by using the integrated capacity and the elapsed time corresponding to the total data collection period. 4.5.4 Effective power input calculation 4.5.4.1 Steady state test An average electric power input shall be determined from the integrated electrical power over the same data collection period than the one used for the heating / cooling capacity or heat recovery capacity calculation. 4.5.4.2 Transient with defrost cycle An average electric power input shall be determined on the basis of the integrated electrical power and the time corresponding to the total number of complete cycles during the same data collection period as the one used for the heat capacity calculation. 4.5.4.3 Transient without defrost cycle An average electric power input shall be determined on the basis of the integrated electrical power and the time corresponding to the same data collection period as the one used for the heat capacity calculation. 5 Heat recovery test for multisplit systems 5.1 Test installation 5.1.1 General The heat recovery capacity of the system is determined by measurements in a three room calorimeter or by the air enthalpy method using two or three rooms. The three rooms shall consist of one outdoor room and two indoor rooms, one at the heating condition and the other at the cooling condition. The two room air enthalpy method shall have one room at the outdoor condition and the other at the common indoor side condition given in Table 15 of EN 14511-2:2004. The calorimeter room and air enthalpy methods are described in annex A and annex B respectively. Each (责任编辑:admin) |
