Experimental study on cool storage air-conditioning system with spherical capsules packed bed

An experimental investigation on operation characteristics of cool storage air-conditioning system with spherical capsules packed bed was performed in this paper. The experimental system of cool storage air-conditioning system with spherical capsules packed bed was set up. The performance parameters such as the evaporation pressure and the condensation pressure of refrigeration system, the refrigeration capacity and the coefficient of performance (COP) of the system, the cool storage rate and the cool storage capacity in the cool storage tank, the inlet and outlet coolant temperatures in the cool storage tank during charging period, and the cool discharge rate and the cool discharge capacity in the cool storage tank, the outlet and inlet coolant temperatures in the cool storage tank and the outlet and inlet air temperatures in room fan coil unit during discharging period were investigated. The experimental results indicated that the cool storage air-conditioning system with spherical capsules packed bed has better performances and can stably work during charging and discharging period.
