Refrigerant amount adjustment method, device, system and air conditioner for temperature adjustment equipment

Abstract

The invention relates to a method, device and system for adjusting the refrigerant amount of temperature adjusting equipment and an air conditioner. The air suction superheat degree of a unit of the temperature adjusting equipment is acquired; a first electronic expansion valve opening control signal is output according to the air suction superheat degree and a preset air suction superheat degreesection; when the air suction superheat degree is within the preset air suction superheat degree region, the condensation supercooling degree of the unit of the temperature adjusting equipment is acquired; and a second electronic expansion valve opening control signal is output according to the condensation supercooling degree and a preset condensation supercooling degree section. Refrigerant of the unit is precisely controlled through the air suction superheat degree, the condensation supercooling degree, the preset air suction superheat degree section and the preset condensation supercoolingdegree section, the refrigerant of the unit can be completely used for evaporation heat exchange, and meanwhile redundant refrigerant is used for increasing the condensation supercooling degree, so that the capacity of the unit is improved, the capacity and the energy efficiency of the unit are higher, and the unit can continuously run at high energy efficiency.

Description

technical field [0001] The present application relates to the technical field of temperature adjustment equipment control, in particular to a method, device, system and air conditioner for adjusting the amount of refrigerant in temperature adjustment equipment. Background technique [0002] In recent years, with the continuous progress of social development and the continuous improvement of consumers' requirements for quality of life, the demand for high-energy-efficiency temperature adjustment equipment such as air conditioners is increasing. As we all know, thermostat is a kind of electrical appliance with high power consumption, and its operating cost is relatively expensive for most families. Therefore, various thermostat manufacturers have also made many attempts to save energy and energy efficiency of thermostat. Improve the performance of the temperature adjustment equipment unit and reduce energy consumption. [0003] During the long-term operation of the temperatur...

Problems solved by technology

[0004] Based on this, it is necessary to provide a solution for the technical problem that the evaporation capacity of the refrigerant in the traditional evaporator is less than the storage capacity, and the excess refrigerant does not play a role in heat exchange during system operation, resulting in low energy efficiency of the temperature adjustment equipment unit. Refrigerant amount adjustment method, device, system and air conditioner for temperature adjustment equipment that improve the operating energy efficiency of temperature adjustment equipment units
