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

Embodiment Construction

[0040] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0041] At first, briefly explain the technical idea of ​​the present invention:

[0042] According to theoretical analysis and experimental verification, the factors that have a greater impact on the heating energy efficiency ratio of the air conditioner during heating operation are the indoor temperature and the frequency of the compressor, while the outdoor temperature, the speed of the internal unit and the speed of the external unit have little influence on the heating energy efficiency ratio . Therefore, in order to simplify the online detection process of heating energy efficiency ratio and ensure the accuracy of detection, this application proposes to use the heating energy efficiency ratio affected by real-time indoor temperature and real-t...

Abstract

The invention discloses an air conditioner heating energy efficiency ratio and heating capacity online detection method. The heating energy efficiency ratio online detection method comprises the steps that in the operation process of an air conditioner, real-time compressor frequency, the real-time indoor temperature, the real-time outdoor temperature, the real-time indoor unit rotation speed and the real-time outdoor unit rotation speed are obtained; real-time energy efficiency ratios corresponding to the real-time compressor frequency and the real-time indoor temperature are determined according to a core energy efficiency ratio benchmark table; a real-time outdoor temperature energy efficiency ratio correction factor is determined according to the real-time outdoor temperature and the rated outdoor temperature, a real-time indoor unit rotation speed energy efficiency ratio correction factor is determined according to the real-time indoor unit rotation speed and the rated indoor unit rotation speed, and a real-time outdoor unit rotation speed energy efficiency ratio correction factor is determined according to the real-time outdoor unit rotation speed and the rated outdoor unit rotation speed; and the real-time heating energy efficiency ratio is determined according to the real-time core energy efficiency ratio and all the energy efficiency ratio correction factors. By the application of the air conditioner heating energy efficiency ratio and heating capacity online detection method, real-time detection of the heating energy efficiency ratio and the heating capacity in different operation conditions of the air conditioner can be achieved.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning performance parameter detection, and in particular relates to an online detection method for air-conditioning heating energy efficiency ratio and heating capacity. Background technique [0002] The heating energy efficiency ratio of the air conditioner is the ratio of the heating capacity of the air conditioner to the operating power, and it is a parameter to measure the heating performance of the air conditioner. [0003] In the prior art, the heating 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 heat output and the rated power consumption under the rated state. 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 heating energy efficiency ratio stated on t...
