Abstract

The invention discloses a method and device for adjusting the exhaust temperature of a compressor. The method comprises: detecting the exhaust temperature of the compressor when the electronic expansion valve adjusts the exhaust temperature of the air conditioner compressor to a target value; When a change in the discharge temperature of the compressor is detected, the electronic expansion valve is adjusted. The present invention detects the discharge temperature of the compressor when the discharge temperature of the air conditioner compressor is adjusted by the electronic expansion valve to reach the target value, and adjusts the electronic expansion when the discharge temperature of the compressor is detected to change. The valve can dynamically adjust the electronic expansion valve according to parameters such as the discharge temperature or suction temperature of the compressor, so as to achieve a reasonable temperature range.

Description

technical field [0001] The invention relates to the field of electrical equipment, in particular to a method and a device for adjusting the discharge temperature of a compressor. Background technique [0002] The air conditioner performs cooling operation in a high temperature environment, or is installed in some special environments (such as the air conditioner installation space is small, resulting in poor heat exchange of the outdoor unit), and due to the lack of Freon, dirty condensers, and evaporators, etc., the compression If the exhaust temperature of the compressor is too high, high exhaust gas will cause chemical reactions in the compressor shell, oil, refrigerant, tube group, etc., which will shorten the service life of the compressor. [0003] The air conditioner operates in a low temperature environment, or the discharge temperature of the compressor is too low due to the large opening of the throttle element, etc. The low discharge temperature will cause the tem...
