Adjustable parallel circulating device for CO2 heat pump and circulating mode

Abstract

The invention discloses an adjustable parallel circulating device for a CO2 heat pump and a circulating mode. The device of the invention comprises a throttle valve, an evaporator and a compressor which are connected in sequence, wherein a first condenser and a second condenser are connected in parallel between the compressor and the throttle valve to form a circulation loop, and CO2 gas is adopted to serve as cycle fluid; the first condenser is connected a water supply system, and the second condenser is connected to an air-conditioning system; a first valve is arranged between the water inlet of the first condenser and the water outlet of the second condenser, and a second valve is arranged between the water outlet of the first condenser and the water outlet of the second condenser; the evaporator is connected to a heat transfer system, and a first bypass and a second bypass are connected between the second condenser and the heat transfer system; and a third bypass and a fourth bypass are connected between the evaporator and the air-conditioning system, and the first bypass, the second bypass, the third bypass and the fourth bypass are respectively provided with a valve. By setting the open / closed states of each valve, the invention can realizes the refrigeration, heat supply and life hot water supply functions of the traditional air conditioner, and can be widely applied in houses and production.

Description

technical field [0001] The invention relates to a heat pump circulation mode, in particular to an adjustable CO 2 Heat pump parallel circulation system. Background technique [0002] Energy and environmental issues are two major social issues facing contemporary mankind. Energy is the driving force for economic development and the material basis for the development of human society. However, with the rapid growth of the world economy and population, energy consumption has increased dramatically. The cumulative effect of excessive development and consumption of energy has produced environmental problems that restrict economic development and affect human survival. The climate change caused by greenhouse gas emissions has posed a serious challenge to the global ecology and the development of human society. The greenhouse effect and the destruction of the ozone layer have become important environmental factors restricting the coordinated and stable development of my country'...

AI Technical Summary

Problems solved by technology

In addition, domestic hot water is mostly obtained from the ambient temperature by electric heating or gas heating, which greatly consumes high-quality energy and primary energy.

In addition, the artificial refrigerants used in traditional air conditioners have adverse effects on the greenhouse effect and the destruction of the ozone layer.
