Refrigence air -conditioning refrigeration training device

Ice -storage cold --r conditioner uses the night trough load power to store ice storage in the ice -storage device. During the day melting ice to release the stored cold amount, reducing the power load and --r conditioning system installed capacity of the power grid during the peak period of the power grid. The direction of development. This tr--ning device is a new tr--ning equipment developed and designed based on the practical teaching of "Refrigeration and *r Conditioning System Principles, Engineering Design and Application" and "Energy Storage *r Conditioning Technology and its Development". The entire device adopts a direct evaporation ice system. The system is m--nly composed of refrigeration units, ice storage devices, --r -conditioning ending devices, --r -conditioning circulating water pumps, ethylene glycol pumps, and refrigerant (ethylene glycol aqueous solution). Suitable for tr--ning and teaching of related courses such as --r -conditioning engineering, building environment and equipment engineering.
