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.
