Control method and device for adjusting high-temperature refrigerating capacity of air conditioner and air conditioner

Abstract

The invention provides a control method and device for adjusting the high-temperature refrigerating capacity of an air conditioner and the air conditioner, and relates to the technical field of air conditioners. The control method comprises the following steps that 1, the temperature of an inner coil and the temperature of an outer coil are obtained, wherein the temperature of the inner coil is anindoor side coil temperature, and the temperature of the outer coil is an outdoor side coil temperature; 2, a temperature range is determined according to the temperature of the inner coil and the temperature of the outer coil, wherein the temperature range comprises a temperature range where the temperature of the inner coil is located and a temperature range where the temperature of the outer coil is located; 3, whether the change amount of the temperature of the inner coil is acquired is judged according to the temperature ranged, and if so, the variation amount is acquired; and 4, according to the temperature range and or the amount of change, the detection and adjustment of the refrigeration effect are controlled. According to the control method, the temperature of the outer coil andthe temperature of the inner coil are combined, the variation of the temperature of the inner coil is detected multiple times, the accurate adjustment of parameters is achieved, the real-time adjustment of the temperature is achieved through multiple detection, timely feedback of comfort control is achieved, and meanwhile the use effect of a user is improved.

Description

technical field [0001] The present invention relates to the technical field of air conditioning, in particular to a control method and device for adjusting the high-temperature cooling capacity of an air conditioner, and an air conditioner. Background technique [0002] During the cooling process of the air conditioner, as the ambient temperature rises, the system pressure and the exhaust temperature rise, and the condenser's external heat dissipation capacity decreases, resulting in the attenuation of the cooling capacity under high temperature conditions. The cooling performance is poor and the user experience is poor. [0003] The existing technology generally aims at the increase of ambient temperature or system pressure. Through the detected ambient temperature or pressure, the air volume on the condensation side is improved, the heat exchange efficiency is improved, and the condensation temperature is reduced, thereby increasing the high-temperature cooling capacity. ...

AI Technical Summary

Problems solved by technology

On the one hand, the refrigeration system is a complex and interrelated state. Increasing the high-temperature cooling capacity only based on a certain factor often leads to poor control effects; Judgment, it is impossible to improve the high-temperature cooling capacity to the greatest extent, and it is impossible to realize real-time monitoring and precise adjustment
