Air heat exchanger for air conditioner

Abstract

The invention discloses an air heat exchanger for an air conditioner, aiming at the technical problem that the pressure drop of fluid flowing through the heat exchanger is too high. According to the technical scheme of the invention, the heat exchanger for the air conditioner comprises an air heat exchanger, and a concentration / separation device is arranged at the joint of the air heat exchanger and a main pipeline. Comparing with the prior art, flow uniform distribution is realized by the adoption of an inner pipe and a distribution pipe, therefore flow distribution is not affected and fluidflowing out from the clearance of the distribution pipe and the inner pipe is not affected, and the object of reducing the total pressure drop of fluid flowing through the heat exchanger is achieved.Through the process, fluid can be uniformly distributed when the heat exchanger serves as an evaporator and the pressure drop of fluid is minimum when the heat exchanger serves as a condenser. Therefore, the concentration / separation device is arranged in an air conditioner heat exchanger, the optimal heat exchanger performance can be realized by the adoption of the adjustment measures, so as to overcome the problem that the too high condensation pressure drop of a heat exchanger for a heat pump results in too low condenser depression and instantaneous vaporization of liquid in front of an expansion valve.

Description

technical field [0001] The invention relates to an air conditioner, in particular to an air conditioner heat exchanger. Background technique [0002] At present, on air conditioners with heat pump function, the air heat exchanger needs to be used as both a condenser and an evaporator. When used as an evaporator, a distributor and capillary assembly are required for better heat transfer. When used as a condenser, the condensed liquid then flows through the assembly, adding resistance. Moreover, the large condensing pressure drop of the heat exchanger used in the heat pump causes the subcooling degree to be too small, and the liquid flashes before the expansion valve. Contents of the invention [0003] The purpose of the present invention is to provide an air-conditioning air heat exchanger, and the technical problem to be solved is to reduce the excessive pressure drop of the fluid passing through the heat exchanger. [0004] The present invention adopts the following te...

And when used as a condenser, the condensed liquid flows through this component again, which increases the resistance

In addition, the condensing pressure drop of the heat exchanger used in the heat pump is too large, and the subcooling degree is too small, and the liquid flashes before the expansion valve.
