Problems solved by technology

Especially under ultra-low temperature or ultra-high temperature conditions (such as below -10 degrees, or above +30 degrees), the cooling or heating energy efficiency of the air conditioner is significantly reduced
[0003] At the same time, the performance parameters of the existing air conditioners cannot be corrected according to changes in the environment, so when the external environment changes greatly, it is easy to cause serious problems of frosting or energy consumption

example 1

[0140] Example 1, according to the above formulas (4), (5), (6) and the above multiple curves, it can be known that with the increase of the working time of the air conditioner, the outlet temperature of the evaporator will increase too much, resulting in a trend of COP decline. To maintain a stable COP, the opening of the expansion valve must be reduced to reduce the refrigerant flow. because Therefore, the adjustment of the electronic expansion valve opening can be realized by correcting the TSH according to the ambient temperature. For example, when the ambient temperature is high, it is easy to cause the outlet temperature of the evaporator to increase too much. In order to maintain a stable COP, for example, increase the target superheat value by 1-2° to reduce the opening degree P of the electronic expansion valve. At the same time, at different ambient temperatures, the correction value for setting the target superheat is also different.

example 2

[0141] Example 2, according to the above formulas (4), (5), (6) and the above multiple curves, the temperature of the condenser rises to a certain level, and the pressure of the air conditioner will fluctuate greatly. In order to make the pressure of the air conditioner stable, it is necessary to increase The opening degree of the electronic expansion valve is used to increase the outlet temperature of the evaporator. If the ambient temperature is high and the condenser temperature rises to a certain level, according to the system stability curve, in order to ensure the stability of the air conditioner, the target superheat value should be reduced by 1-2° to increase the opening P of the electronic expansion valve. At different ambient temperatures, the set target superheat correction value is also different.

Abstract

The invention discloses a server-based method for optimizing performance parameters of an air conditioner, the air conditioner and a server. The method comprises that the server acquires identification information of the air conditioner and local environmental climate information; optimum values of performance parameters of the air conditioner are determined according to the identification information and the local environmental climate information; and the optimum values of the performance parameters are fed back to the air conditioner to enable the air conditioner to update corresponding set performance parameters into the optimum values of performance parameters. According to the server-based method for optimizing performance parameters of the air conditioner, the air conditioner and the server, performance parameters of the air conditioner are adjusted in real time according to environmental climate changes, and therefore, the air conditioner is guaranteed to be always in the optimum operating state.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a method for optimizing performance parameters of an air conditioner based on a server, an air conditioner and a server. Background technique [0002] Existing air conditioners use a refrigeration cycle to keep the temperature and humidity of the space in an appropriate state. Wherein, the refrigeration cycle process includes: compression, condensation, expansion and evaporation processes of refrigerant. These refrigeration cycle processes are realized by compressors, condensers, expansion valves, and evaporators. The evaporator is set indoors to absorb heat; the compressor is set outdoors. Among them, changes in the outdoor ambient temperature and ambient humidity will directly affect the cooling effect. Especially under the conditions of ultra-low temperature or ultra-high temperature (such as below -10 degrees, or above +30 degrees), the cooling or heating energy e...
