Efficient and environment-friendly carbon dioxide air source heat pump device

Abstract

The invention discloses an efficient and environment-friendly carbon dioxide air source heat pump device which comprises a compressor, a condenser, an evaporator and a liquid storage device. The air outlet end of the compressor is connected with the air inlet end of a three-way valve, one air outlet end of the three-way valve is connected with the evaporator, the other air outlet end of the three-way valve is connected with the condenser, the condenser and the evaporator are connected through a throttling element, the condenser and the evaporator are both connected with the air inlet end of the liquid storage device in a penetrating mode, the air outlet end of the liquid storage device is connected with the air inlet end of the compressor in a penetrating mode, and defrosting mechanisms are arranged on the condenser and the evaporator. The lower side of the condenser and the lower side of the evaporator are each provided with a drainage mechanism so that the heat pump device can be used for multiple purposes, heating can be achieved in winter, refrigerating can be achieved in summer, the frosting condition of the evaporation side of the heat pump device can be reduced, energy consumption is reduced, and the service life of the device is prolonged.

Description

technical field [0001] The invention relates to the technical field of air source heat pump devices, and specifically relates to an efficient and environment-friendly carbon dioxide air source heat pump device. Background technique [0002] The air source heat pump is a refrigeration and heating technology based on the reverse Carnot cycle principle. The system uses the compressor to do work, obtains low-grade heat energy from the air in nature, and provides a device for high-grade heat energy that can be used by people. The heat in the air is transferred to the water through the refrigerant, which is used for heating in winter, cooling in summer, or providing domestic hot water. Ordinary air energy heat pumps or ground source heat pumps and other equipment have successively used Freon as refrigerants, such as R12, R22, R407A, R407C, etc. However, freon refrigerants will destroy the ozone layer of the atmosphere and cause the greenhouse effect, which is not conducive to th...

Problems solved by technology

However, freon refrigerants will destroy the ozone layer of the atmosphere and cause the greenhouse effect, which is not conducive to the protection of the environment. Therefore, it is necessary to replace more environmentally friendly refrigerants. The decrease in operating efficiency is not conducive to the efficient conversion of energy. Therefore, we provide an efficient and environmentally friendly carbon dioxide air source heat pump device
