Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to an air conditioner with a low-temperature refrigeration function. Background Art

[0002] An air conditioner is a device used to adjust the indoor temperature, humidity and air quality. Its main functions include cooling, heating, dehumidification and air purification. However, the speed of the external fan of the existing room air conditioner is divided into gears and regions according to the operating frequency and the ambient temperature. The stability of the control system operation is poor and the refrigeration operation range is narrow. When the external environment changes and the air conditioner operation load changes, the outdoor motor is divided into gears and regions for control, and the speed of the outdoor unit cannot be accurately controlled, resulting in large changes in the condensing temperature and the system load, resulting in unstable system operation. Moreover, under low ambient temperatures, the air conditioner stops running due to the low external ambient temperature, which will reduce the comfort of the room air conditioner and also limit the scope of use of the air conditioner. Summary of the invention

[0003] 1. Technical issues to be resolved In view of the deficiencies in the prior art, the present invention provides an air conditioner with a low-temperature refrigeration function, which solves the problems of the external fan speed of the existing room air conditioner being divided into gears and regions according to the operating frequency and the ambient temperature, the poor stability of the control system operation, and the narrow refrigeration operation range.

At this time, the support plate and the air conditioner body are in a fixed state, which ensures the stability of the air conditioner body during use.
