Description

technical field [0001] The invention belongs to the technical field of air conditioner performance parameter detection, and in particular relates to an online detection method for air conditioner refrigeration energy efficiency ratio and cooling capacity. Background technique [0002] The energy efficiency ratio of the air conditioner is the ratio of the cooling capacity of the air conditioner to the operating power. It is a parameter to measure the cooling performance of the air conditioner. [0003] In the prior art, the cooling energy efficiency ratio of the air conditioner is the nominal value marked on the nameplate of the air conditioner, which is the ratio calculated according to the rated cooling capacity and the rated power consumption under rated conditions. 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 cooling energy efficiency ratio declared on t...

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

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