Abstract

The invention provides a method and device for debugging a flow path of a heat exchanger, and a debugging device for a flow path of a heat exchanger. The method includes: obtaining flow information and temperature information of each branch; the temperature information includes the first temperature and the second temperature after the electronic expansion valve; according to the flow information and temperature information of each branch, calculate the flow difference and temperature difference; wherein, the temperature difference includes the first temperature difference and the second temperature difference, and the first temperature difference is the first temperature difference of each branch. The difference between the temperature and the second temperature, the second temperature difference is the difference between the first temperature of the two branches or the difference between the second temperature of the two branches; according to the flow difference and temperature difference, the electronic expansion of each branch is adjusted The opening of the valve is such that the flow difference and temperature difference are less than or equal to the preset threshold. The present invention optimizes the flow path more systematically, can reduce manpower experiment labor at the same time, and debugs the flow path more scientifically and accurately.

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...
