Problems solved by technology

Therefore, for the current inverter air conditioner, only the compressor can be infinitely adjusted. The outdoor motor cannot be intelligently adjusted according to the state of the refrigeration system, nor can it adjust the outdoor speed accordingly according to the frequency of the compressor. , in addition to the waste of electricity, it also brings about the problem of excessive heat exchange or insufficient heat exchange, which leads to condensation and comfort problems such as frosting and icing of the indoor evaporator during low-temperature cooling

Embodiment Construction

[0028] Referring to accompanying drawing 1, air conditioner outdoor motor control method of the present invention comprises the following steps:

[0029] (1) Turn on the machine and run the outdoor motor at full speed for 3 minutes;

[0030] (2) According to the outdoor ambient temperature T 环 It is divided into four intervals: the first interval, the second interval, the third interval and the fourth interval:

[0031] 1) For outdoor ambient temperature T 环 The operating frequency of the compressor in each interval is specified as follows: set the low operating frequency F(i) of the outdoor compressor min and high operating frequency F(i) max , the operating frequency of the compressor is limited to F(i) min and F(i) max Between, (i=1, 2, 3, 4).

[0032] 2) Such as the outdoor ambient temperature T 环 In the first interval, set the maximum allowable speed V of the outdoor fan motor max , the outdoor fan motor is fixed at the allowable maximum speed V max run on, that ...

Abstract

The invention discloses a method for controlling an outdoor motor, which can perform adaptive operation according to an environmental temperature and the frequency state of a compressor. The method saves the wasted work of the motor and enables an air conditioner to always run in the most energy-saving state. The method is designed according to the characteristics of a convertible frequency air-conditioner and can solve the comfortable problems of condensation caused by excessive heat exchange and insufficient heat exchange, frosting and icing of indoor evaporators during low-temperature refrigeration, and the like.

Description

technical field [0001] The invention relates to the technical field of air conditioners in electrical equipment, and more specifically relates to a method for controlling an outdoor motor of an air conditioner. Background technique [0002] For inverter air conditioners, the biggest advantage is that they can adaptively change the output of cooling capacity / heating capacity according to the heat load of the room. The current inverter air conditioners change the mass flow rate in the system by adjusting the speed of the compressor. to adjust the output capacity. Due to the wide adjustment range of the inverter air conditioner, the general adjustment frequency range can reach about 80Hz. Corresponding to such a large compressor frequency adjustment range, the adjustment ability of the outdoor motor is very general. The outdoor motor generally adopts a tap motor or a DC motor; the gear position of the tap motor is fixed at 2nd or 3rd gear; at present, the outdoor speed of the ...
