Air conditioner device refrigerating capacity test method based on multi-dimensional curve fitting algorithm

Abstract

The invention discloses an air conditioner device refrigerating capacity test method based on a multi-dimensional curve fitting algorithm, and belongs to the technical field of air conditioner refrigerating capacity test methods. According to the principle on which the test method is based, a reference prototype physical model of an air conditioner device is established and used as a research object, and a refrigerating capacity mathematical model of the air conditioner device under any work condition is obtained by establishing a multi-dimensional curve fitting mathematical model between the refrigerating capacity of a reference prototype of the air conditioner device and all influencing parameters and conducting training simulation through multiple sets of sample data including the normal condition. By means of the mathematical model, the refrigerating capacity of the reference prototype of the air conditioner device under any work condition can be obtained and used as the theoretical value of the refrigerating capacity of a tested air conditioner device of the same type. Under the same test work condition, the actual refrigerating capacity of the tested air conditioner device is obtained. A refrigerating capacity test device or instrument manufactured through the test method can be used for refrigerating capacity tests of the air conditioner device and is widely used for air conditioner device refrigerating capacity tests of traffic vehicles, ships, civil use and industrial application.

Description

Technical field: [0001] The invention relates to a method for testing the cooling capacity of an air conditioner based on a multidimensional curve fitting algorithm, and belongs to the technical field of testing methods for the cooling capacity of an air conditioner. Background technique: [0002] The cooling capacity test of the air conditioner is mainly carried out in accordance with the relevant standards and the principle of the enthalpy difference method. This test method in accordance with relevant standards is inseparable from complex operating condition control and air volume control and other hardware equipment, and is almost limited to laboratory applications. However, the demand for testing the cooling capacity of air-conditioning devices is common in the application process of air-conditioning devices. For example, vehicle-mounted air conditioners are widely used, but because the failure rate is much higher than that of ordinary household air conditioners, it is...

AI Technical Summary

Problems solved by technology

[0013] The traditional performance test method of air conditioner must be carried out in a specific laboratory according to the specified working conditions, and it is almost impossible to complete the test under other application conditions

In addition to the harsh test environment, in actual operation, the disturbance of the external environment will lead to unstable test conditions, and even cause the air temperature and humidity in the test room to deviate from the allowable value of the specification. Carry out constant monitoring and adjustment, which consumes a lot of time and energy in the adjustment of working conditions

Therefore, the traditional test method cannot be used without the special test system of the laboratory.
