Experimental measurement on characteristics of cool storage air conditioning system

The experimental apparatus of cool storage air conditioning system is designed and constructed. The characteristics of cool storage air-conditioning system are experimentally measured. The temperature variation of coolant in the evaporator is presented by experiments. The refrigerant temperature in the evaporator and the compressor discharge temperature are also shown. The cool storage experiments are carried out to measure the refrigeration capacity of the chiller in cool storage mode, and the cool storage capacity in the storage tank. The measured results show that the coolant temperature difference between inlet and outlet in the evaporator, the refrigerant evaporating temperature, discharging temperature of the compressor and the refrigeration capacity of the chiller during cool storage period can maintain stable. The cool storage capacity in the storage tank approximately increases in linearity with cool storage time. This indicates the cool storage air conditioning system can stably operate.
