System for detecting heat exchanger of air conditioner

Abstract

The invention discloses a system for detecting a heat exchanger of an air conditioner, which comprise a low-pressure circulating tank (5), a liquid delivery pump (6) and a detected heat exchanger (8), wherein the low-pressure circulating tank (5) is connected with an input end and an output end of the detected heat exchanger (8) through an indoor input pipe (7) and an indoor output pipe (9) respectively; the liquid delivery pump (6) is positioned between the low-pressure circulating tank (5) and the indoor input pipe (7); and the low-pressure circulating tank (5) is connected with an outdoor unit of the air conditioner through an outdoor output pipe (13) and an air return pipe (10). The system is characterized in that the joint of the low-pressure circulating tank (5) and the outdoor output pipe (13) is provided with a ball float valve (4) for controlling the coolant conveying quantity of the outdoor output pipe (13), and the ball float valve (4) is in the low-pressure circulating tank (5). The detection system of the invention combines an enthalpy difference laboratory or a thermal balance laboratory for use, and can quickly compare the heat exchanging performances of different heat exchangers; besides, the system has the advantages of simple structure, convenient mounting, low cost and high use value.

Description

Technical field [0001] The technology field of air -conditioners in electrical equipment involves the technology field of air -conditioners in electrical equipment. More specifically, it involves a detection system that involves the maximum heat exchange ability test and the comparison test of the heat exchange capacity of the air -conditioning heat exchanger. Background technique [0002] With the rapid development of the air -conditioning industry, the speed of updating air -conditioning products is becoming faster and faster, and high -efficiency heat exchange products are becoming more and more popular with consumers.The current enterprise is mainly carried out in the air conditioning performance test in the laboratory or thermal balance room. Because it is impossible to accurately know the maximum heat exchange ability of the heat exchanger, it can only be explored by continuously optimizing the air -conditioning system and multiple trials.The ability of the device has spent...

[0003] In addition, in the comparison of the heat transfer performance of heat exchangers, the traditional method is to use different heat exchangers to obtain the heat transfer performance, so as to judge the performance of the product. The consistency of parameters makes it difficult to accurately judge different heat exchangers with similar performance, or even cause misjudgment, which has a significant impact on subsequent product development
