specific example
[0050] A specific example of typical press frequency, typical indoor temperature, typical core energy efficiency ratio and typical relationship is as follows:
[0051] Table 1 shows a typical core energy efficiency ratio table composed of typical press frequency, typical indoor temperature and typical core energy efficiency ratio.
[0052] Table 1 Typical core energy efficiency ratio table
[0053]
[0054] The typical core energy efficiency ratio table shown in Table 1 above includes three typical indoor temperatures of 25°C, 30°C, and 35°C, as well as three typical compressor frequencies, which are 43hz, 77hz, and 84hz. Each typical press frequency and each typical indoor temperature correspond to a typical core energy efficiency ratio, and there are nine typical core energy efficiency ratios. Take the typical core energy efficiency ratio of 4.49 corresponding to a typical indoor temperature of 25℃ and a typical press frequency of 43hz as an example, briefly explain the method of ...

The invention discloses a method for detecting the heating energy efficiency ratio and heating amount of an air conditioner on line. The method for detecting the heating energy efficiency ratio on line comprises the steps that in the air conditioner running process, the real-time press frequency, the real-time indoor temperature, the real-time outdoor temperature, the real-time indoor unit rotating speed and the real-time outdoor unit rotating speed are obtained; the real-time core energy efficiency ratio corresponding to the real-time press frequency and the real-time indoor temperature is determined according to the typical press frequency, the typical indoor temperature, the typical core energy efficiency ratio and typical relationship; the real-time outdoor temperature energy efficiency ratio correction factor is determined according to the real-time outdoor temperature and the rated outdoor temperature, the real-time indoor unit rotating speed energy efficiency ratio correction factor is determined according to the real-time indoor unit rotating speed and the rated indoor unit rotating speed, and the real-time outdoor unit rotating speed energy efficiency ratio correction factor is determined according to the real-time outdoor unit rotating speed and the rated outdoor unit rotating speed; and the real-time heating energy efficiency ratio is determined according to the real-time core energy efficiency ratio and all energy efficiency ratio correction factors. By means of the method, real-time detection of the heating energy efficiency ratio and the heating amount of the air conditioner under different operation conditions can be achieved.
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 ...
