Abstract

The invention discloses a cascade lithium bromide refrigeration and cold storage system which comprises a lithium bromide absorption refrigeration system containing a lithium bromide absorption cooling water loop and a lithium bromide refrigerant loop, an electric refrigeration system containing an electric refrigeration cooling water loop and an electric refrigeration refrigerant loop, and an ice storage system containing a refrigerant loop. Both a first evaporator and a plate heat exchanger form separately connected circulating chilled water loops respectively with a chilled water pump, a water separator, terminal equipment and a water collector shared by the two, wherein the terminal equipment is connected with an air conditioner that needs cooling. The cascade lithium bromide refrigeration and cold storage system can not only provide efficient and reliable cooling, but also can make and store ice when demand for electricity is low, thus enabling efficient ice making to be realized. Furthermore, the system has extremely low power consumption and can effectively save energy and cost.

Description

technical field [0001] The invention relates to a cooling system for an air conditioner, in particular to a cascaded lithium bromide refrigeration and cold storage system. Background technique [0002] Air conditioning energy saving is an important part of building energy saving. At present, there are three commonly used cooling methods for air conditioners. The first is ice storage alone for cooling, the second is ice storage combined with electric refrigeration units for cooling, and the third is lithium bromide absorption refrigerators or electric refrigeration refrigerators. For cooling. [0003] Lithium bromide absorption chillers can use waste steam and waste heat in thermal power plants or industrial production as heat sources to provide chilled water for air conditioning or industrial cooling. It has the characteristics of improving energy utilization, alleviating the contradiction between power supply and demand in summer, and being conducive to environmental prote...
