apparatusThe experimental system could be split into two parts: a conven-tional air-cooled refrigeration system using R-410A coolant and anevaporative pre-cooling system with a temperature control device.The combination of condenser and evaporative pre-cooling systemwas regarded as the outdoor unit, while the evaporator was con-sidered as the indoor unit, as depicted in Fig. 1. The refrigerationunit was driven by a 7.4 kW scroll compressor, with an evapora-tor capacity of 5.3 kW to 7 kW. The dimension of the evaporatorwas 48 cm × 61 cm × 2 rows × 3.15 FPCM, while the capacity of thecondenser was 11 kW and its dimension was 63.5 cm × 76.2 cm × 2
