Embodiment 1

[0035] Embodiment 1 of the present invention is the first type of multi-branch outdoor heat exchanger for synchronous heat exchange. The fan 5 of the multi-branch outdoor heat exchanger for synchronous heat exchange is the upper air outlet, and its wind speed distribution vector diagram conforms to the upper triangle. When the structure of the heat exchanger is determined, this specific air supply mode has a one-to-one correspondence with the upper triangle distribution vector diagram of the wind speed. It can be seen from the upper triangle wind speed distribution vector diagram that the upper part of the heat exchanger has a higher wind speed, so when the external air sweeps across the upper branch of the heat exchanger, the effect of forced heat exchange with the refrigerant in the tube is good, so the present invention makes the uppermost part of the outdoor heat exchanger One of the branches is set as the subcooling coil 3; the wind speed at the lower part of the heat exc...

Abstract

The invention discloses a multi-branch outdoor heat exchanger for synchronous heat exchange, including a superheating coil, a multi-branch heat exchange coil, a subcooling coil, a high-pressure liquid storage tank, a fan, a superheating coil and a subcooling plate The tubes are respectively arranged in the positions with the worst and best heat exchange effects in the outdoor heat exchanger and parallel to the multi-branch heat exchange coils. The invention is applicable to various air-conditioning systems, can effectively solve the problem of loss of supercooling degree, enhance the working stability and reliability of the expansion valve, prevent the compressor from performing wet compression, and effectively improve the system efficiency and the safety and reliability of operation.

Description

technical field [0001] The invention relates to a multi-branch outdoor heat exchanger, specifically a multi-branch outdoor heat exchanger for synchronous heat exchange, belonging to the technical field of building environment and equipment engineering. Background technique [0002] The multi-branch outdoor heat exchanger is a kind of partition wall heat exchanger that makes the refrigerant fluid and the indoor air fluid undergo forced heat exchange, thereby changing the temperature of the refrigerant. At present, most of the outdoor heat exchangers do not have subcooling equipment, and a few are equipped with subcooling equipment. Often due to the unreasonable arrangement of subcooling coils, the actual subcooling effect of the system is greatly reduced, and it is difficult to improve the energy efficiency ratio of the system. In addition, the existing technology does not realize synchronous heat exchange. Generally, outdoor heat exchangers are only suitable for cooling-only...
