Description

Technical field [0001] The invention belongs to the technical field of air conditioner performance parameter detection, and specifically relates to a method for on-line detection of air conditioner heating energy efficiency ratio and heating capacity. Background technique [0002] Air-conditioning heating energy efficiency ratio is the ratio of air-conditioning heating capacity to operating power. It is a parameter to measure the heating performance of air-conditioning. The higher the heating energy-efficiency ratio, the lower the power consumption of the air-conditioning. [0003] In the prior art, the air-conditioning heating energy efficiency ratio is the nominal value marked on the air-conditioning nameplate, which is the ratio calculated based on the rated heating capacity and the rated power consumption in a rated state. However, in actual use, the air conditioner is affected by the use environment, and it is difficult to reach the rated operating conditions. Therefore, the ...

AI Technical Summary

Problems solved by technology

However, in the actual use of the air conditioner, it is difficult to reach the rated working condition due to the influence of the use environment.

Therefore, the nominal heating energy efficiency ratio on the nameplate of the air conditioner can only serve as a reference in the actual use process, and cannot present the actual heating performance in real time

Since the real-time heating energy efficiency ratio of the air conditioner cannot be obtained, the actual heating capacity during the operation of the air conditioner cannot be obtained
