High-temperature refrigeration air conditioner and high-temperature refrigeration control method

Abstract

The invention relates to the technical field of air conditioners, in particular to a high-temperature refrigeration air conditioner and a high-temperature refrigeration control method. The high-temperature refrigeration air conditioner comprises a compressor, an outdoor heat exchanger, a throttling device and an indoor heat exchanger which are connected to form a refrigeration loop or a heating loop. The high-temperature refrigeration air conditioner further comprises a wind shielding device for shielding the indoor heat exchanger, a driving mechanism connected with the wind shielding device, and a control module for controlling the driving mechanism. A pressure sensor connected with the control module is arranged on a pipeline between the outdoor heat exchanger and the compressor, and the control module adjusts the shielding area, shielded by the wind shielding device, of the indoor heat exchanger through the driving mechanism according to data of the pressure sensor. According to the high-temperature refrigeration air conditioner, it is achieved that pressure can be kept within a proper range during refrigeration in the outdoor high-temperature environment, the problem that an air conditioning system cannot run in severe working conditions due to too high pressure is solved, and the running reliability and comfort in the high-temperature environment are greatly improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a high-temperature refrigeration air conditioner and a high-temperature refrigeration control method, in particular to a high-temperature refrigeration air conditioner and a high-temperature refrigeration system capable of effectively improving the reliability and comfort of an air-conditioning unit operating in a high-temperature environment. Control Method. Background technique [0002] At present, during the operation of many air-conditioning units, when the ambient temperature is too high, the pressure and exhaust temperature of the air-conditioning unit system are also relatively high. The ambient temperature that the outdoor heat exchangers of most existing air-conditioning units can generally not exceed 60 Spend. In order to reduce the operating pressure of the system and ensure the reliability of the unit operation, it is common practice to install a high-pressu...
