Adjustable type CO2 heat pump triple-generation circulating device and circulation mode thereof

Abstract

The invention discloses an adjustable type CO2 heat pump triple-generation circulating device comprising a circulation loop formed by sequentially connecting a throttle valve, an evaporator, a compressor and a condenser, wherein a CO2 gas is adapted as a circulating working substance; the condenser is connected with a running water system and an air-conditioning system; the evaporator is connected with a heat exchange system; a first bypass and a second bypass are connected between the condenser and the heat exchange system; 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 valves. The invention can realize the refrigerating and heating functions and the domestic hot water heating of the traditional air conditioner by setting the open and close states of the valves, heat the running water from environmental temperature to80 DEG C and reduce the consumption of high-quality energy sources, thereby finally achieving the purposes of energy saving and emission reduction; and in addition, the invention selects the applicable natural working substance CO2 with a GWP (Global Warming Potential) value and an ODP (Ozone Depletion Potential) value about 0, thereby reducing the influence on greenhouse effect and ozone depletion.

Description

technical field [0001] The invention relates to a heat pump circulation mode, in particular to an adjustable CO 2 Heat pump triple supply cycle 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's...

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.
