Chilled water plant system

Abstract

A chilled water plant system is provided, comprising a secondary refrigerant storage tank, a pump body, a finned heat exchanger and a driving fan. The tank is detachably connected to the finned heat exchanger and communicates with its heat exchange tube via a pipeline to form a closed coolant loop. The pump drives the secondary refrigerant to circulate between the tank and the heat exchange tube. The driving fan forces ambient air to flow through the finned heat exchanger for heat exchange between air and the secondary refrigerant. The tank can also be detachably connected to a refrigerant system to exchange heat with the coolant in the evaporator. The system can keep frozen objects cold and is suitable for longdistance, complex road conditions and small-volume transportation.
