Description

Vapor compression refrigeration system

Technical field

This invention relates to vapor compression refrigeration systems and their use, and more particularly to a cluster of improved vapor compression refrigeration systems and their uses.

Background

Existing refrigeration or heating equipment, for example, an air conditioner whose refrigerant is evaporatively cooled in an evaporator for air conditioning, and its refrigerant vapor is condensed and discharged outside the condenser; and the existing heat pump water heater has a refrigerant vapor therein. Condensation and heat release in the condenser is used to prepare hot water, and the refrigerant is evaporated in the evaporator. The external discharge has been made. Some people have dreamed of grafting the air conditioner and the heat pump water heater into a composite unit, dreaming of refrigeration and air conditioning. It can also produce hot water at the same time, only consume one part of electricity, get two benefits, save energy and reduce emissions, but because of the air conditioner refrigeration and air conditioning, the condensation temperature of the refrigerant is usually 40X~ 45 °C, and the heat pump water heater system When the hot water is taken, the condensation temperature of the refrigerant is as high as 70 °C. If the two are grafted, the summer refrigerating air conditioner will also produce hot water. When the condensation temperature is raised to 70 °C, the cooling capacity will decrease, the power consumption will increase, and the cooling will be performed. The coefficient becomes smaller, and sometimes there is a large power to drive a small load, and the present invention overcomes this technical problem.
