Combined cooling and heating system for comprehensive utilization of clean energy and production waste heat

Abstract

The invention discloses a cold and heat combined supply system capable of comprehensively utilizing clean energy and production waste heat. The cold and heat combined supply system comprises a heatingand refrigerating water supply and return system, and a domestic hot water supply and return system, wherein the heating and refrigerating water supply and return system is equipped with a cold and heat storage water tank; the cold and heat storage water tank is connected with a cold and heat release heat plate type heat exchanger and a cold and heat storage plate type heat exchanger system as well as an air source heat pump system in parallel; the system, a heating water supply and return pipeline and a refrigerating water supply and return pipeline define a circulating system; and a solenoid valve for controlling on and off is arranged on each circulating pipeline. The domestic hot water supply and return system comprises a heat storage water tank which is in parallel connected with anair compressor energy supply system and a solar energy supply and compression system; and the heat storage water tank, the cold storage water tank and the heat storage water tank are equipped with connecting pipelines, so that on and off are controlled according to the needs. According to the cold and heat combined supply system disclosed by the invention, the systems are matched in a staggered mode, so that operation under different modes can be realized, and therefore, different needs of heating and refrigerating a building in different seasons are met, various clean energy is sufficiently utilized, and energy conservation and consumption reduction are realized.
