Method and device for determining energy conservation of operation of air conditioner

Abstract

An embodiment of the invention discloses a method and a device for determining energy conservation of operation of an air conditioner. The method and the device are applied to the field of energy conservation determination of air conditioners. The method comprises presetting refrigeration and heating conditions of an indoor test point and changeable refrigeration and heating conditions of an outdoor test point; obtaining a comprehensive energy efficiency value and a comprehensive performance coefficient value of the air conditioner according to the preset refrigeration and heating conditions of the outdoor test point and the indoor test point; performing comparison on the comprehensive energy efficiency value and a preset energy efficiency standard value and the comprehensive performance coefficient value and a preset performance coefficient standard value; determining that the energy conservation effect of the air conditioner is achieved when the requirements of the conditions of the preset energy efficiency standard value and the preset performance coefficient standard value are met by the comprehensive energy efficiency value and the comprehensive performance coefficient value respectively. The invention also provides the device for determining the energy conservation of the operation of the air conditioner. Compared with the prior art, the refrigeration and heating coefficients of the air conditioner are simultaneously tested through the simulation of the climate change conditions and accordingly the scientific, reasonable and objective determination on the energy conservation determination of the air conditioner is achieved.

Description

technical field [0001] The invention relates to the field of air conditioner manufacturing, in particular to a method and device for judging energy saving in operation of an air conditioner. Background technique [0002] With the change of the living environment, human beings are increasingly aware of the protection of the earth and the awareness of resource conservation, and the requirements for energy saving of equipment in daily life and production are getting higher and higher, including the requirements for energy saving of air conditioners. [0003] There is a method for judging whether the air conditioner is energy-saving. Generally, it is tested and judged according to the test method specified in GB / T7725-2004, and the test value is finally judged according to the requirements of GB12021.3. [0004] However, this test method has the following disadvantages: 1. Only the energy efficiency ratio of the cooling operation is evaluated, and the energy coefficient value of...

Problems solved by technology

[0004] However, this test method has the following disadvantages: 1. Only the energy efficiency ratio of the cooling operation is evaluated, and the energy coefficient value of the heating operation is not evaluated; The air conditioner is tested with the same working condition parameters. Since the outdoor ambient temperature parameters change in actual use, the test value obtained by this test method cannot fully reflect the value in the actual use environment. Based on the above two reasons, the existing The current energy-saving testing and judgment methods for air conditioners are not comprehensive and accurate, so the test results also deviate from the actual situation
