The voltages are representing the driving mode. The voltage level in battery mode is lower. Other voltages shall be specified by the manufacturer. 5.6.3 Heat transmission PTR through the calorimeter box The value shall be determined with the cooling device fitted or mounted. 5.6.4 Steady-state conditions under rated conditions Steady-state conditions under rated conditions are achieved if the following requirements during the measurements are fulfilled: — the inlet air temperature at the evaporator unit TIN VAP, the inlet air temperature at the compressor/condenser unit TIN CON, the inside temperature of the calorimeter box Ti and the temperature of the conditioned test room Te have not changed by more than ± 0,5 K within the last 1 h; — the introduced cooling load PCL or heat load PHL has not changed by more than 1 % within 1 h; — for all these values also within the limits no permanent tendency is allowed. 5.6.5 Energy consumption measurements 5.6.5.1 General The total energy consumptions ET are measured for full and part load for dependent and independent cooling devices. For the cooling devices able to run in standby operation, the total electrical energy consumption ET is also measured at full load and part load. 5.6.5.2 Energy consumption measurements of dependent cooling devices For cooling devices driven by the vehicle motor, the mechanical power shall be determined at the entrance of the unit (like the shaft of compressor, alternator, hydraulic pump) using the speed and torque for each test point. The electrical power of auxiliaries like, e.g. evaporator or condenser fans or generator driven units powered by the electrical DC system of the vehicle, shall be measured separately. The efficiency of the generator of the vehicle engine can be measured separately or an average efficiency factor as defined in Annex D can be used. SIST EN 16440-1:2015
