Air-cooling heat pump using excess heat of compressor for frost prevention

Abstract

The invention discloses an air-cooling heat pump using the excess heat of a compressor for frost prevention, comprising a refrigeration agent loop, a flat panel loop heat pipe and an outdoor unit fan; wherein the refrigeration agent loop is formed by the compressor, an outdoor heat exchanger, a throttling device and an indoor heat exchanger; an exhaust pipe of the compressor is connected with an inlet of the indoor heat exchanger, and an outlet of the indoor heat exchanger is connected with an inlet of the throttling device; an outlet of the throttling device is connected with an inlet of the outdoor heat exchanger, and an outlet of the outdoor heat exchanger is connected with an air suction pipe of the compressor; the flat panel loop heat pipe is formed by a metal evaporation cavity, a condensation part, a vapor phase metal pipeline, a liquid phase metal pipeline and a metal heat dissipation fin; when in heating operation in the winter, the air-cooling heat pump clings to the metal evaporation cavity on the top of the compressor to be heated under the condition of needing no extra power, a working medium inside the cavity is evaporated and vaporized, and the heat is brought to the condensation part and used for heating the air at the inlet of the outdoor heat exchanger, so that frost formation can be prevented.

Description

technical field [0001] The patent of the present invention relates to an anti-frost device for an outdoor heat exchanger of an air-cooled heat pump, in particular to a device for increasing the air inlet temperature of the outdoor heat exchanger by using the residual heat of the compressor to prevent the outdoor heat exchanger of the air-cooled heat pump from freezing under low temperature conditions. A new type of energy-saving anti-frost device for frost. technical background [0002] The air-cooled heat pump unit can absorb the heat in the atmospheric environment through the outdoor heat exchanger, which has dual effects of energy saving and environmental protection, and has been widely used all over the world. When the air-cooled heat pump is running in winter, the outdoor temperature is too low, the sensible heat in the air is very small, and the heat transfer mainly depends on the latent heat in the air. When the surface temperature of the fin surface of the outdoor h...

Problems solved by technology

[0007] This invention aims to effectively solve the problem that the outdoor unit often deteriorates heat transfer due to frost and affects the performance of the air-cooled heat pump system when the air-cooled heat pump is running in winter in the north. Provide a method of using the flat circuit heat pipe to recover the heat originally released to the environment by the compressor to increase the inlet air temperature of the outdoor heat exchanger to achieve the purpose of energy saving and frost prevention
