Abstract

The invention provides a heat exchanger flow path debugging method, device and equipment. The heat exchanger flow path debugging method comprises the following steps: obtaining the flow information and temperature information of each branch, wherein the temperature information comprises first temperature in front of an electronic expansion valve and second temperature behind the electronic expansion valve; according the flow information and temperature information of each branch, calculating the flow difference and temperature difference, wherein the temperature difference comprises first temperature difference and second temperature difference; the first temperature difference is the difference value between the first temperature and the second temperature of each branch; the second temperature difference is the difference value between the first temperature of two branches or the difference value between the second temperature of two branches; and according to the flow difference andthe temperature difference, adjusting the opening degree of the electronic expansion valve of each branch to enable the flow difference and the temperature difference to be equal to or less than thepreset threshold values. According to the heat exchanger flow path debugging method, flow path optimization is more systematic, manpower experimental labor can be reduced at the same time, and flow path debugging is more scientific and preciser.

Description

technical field [0001] The invention relates to the technical field of air conditioner heat exchangers, in particular to a method and device for debugging a flow path of a heat exchanger, and equipment for debugging a flow path of a heat exchanger. Background technique [0002] In the design process of the heat exchanger, in addition to the basic theoretical calculation of the flow path, it is also necessary to cooperate with experimental debugging, simulate the actual use scenarios of the evaporator and condenser through experiments, and verify the scientificity and reliability of the flow path of the heat exchanger by combining experimental data. performance. The flow path design directly affects the performance of the heat exchanger, and has a great influence on defrosting under low temperature conditions. [0003] The current method of debugging the flow path of the heat exchanger is relatively primitive. Generally, the capillary is manually welded, and the capillary is...
