Air-conditioner outdoor motor control method

Abstract

The invention relates to the technical field of air-conditioners in electrical equipment, in particular to an air-conditioner outdoor motor control method, and aims at reducing noise and vibration production in the process of starting to a high rotation speed of an overall unit. The air-conditioner outdoor motor control method includes the following steps: S1, starting up: the rotation speed of an outdoor fan motor is improved to P (i) max from an actual rotation speed P (actual), and then the outdoor fan motor operates for 3minutes, wherein the P (actual) is equal to n P (i) max; and S2, the difference value delta T between temperature of indoor environment and set temperature of an indoor unit is judged. According to the air-conditioner outdoor motor control method, the rotation speed of the starting stage of the outdoor motor is set to be from low to high, and therefore the noise and the vibration are not easily produced in the process of the starting to the high rotation speed of the overall unit, and use comfortable sensation of users is improved.

Description

technical field [0001] The present invention relates to the technical field of air conditioners in electrical equipment, and more specifically, to a method for controlling an outdoor motor of an air conditioner. Background technique [0002] Split air conditioners generally use mechanical compression refrigeration devices. There are four basic components: compressor, evaporator, condenser and throttling device. The four are connected and filled with refrigerant. The compressor is like a galloping heart, making the refrigerant flow continuously in the air conditioner like blood, so as to adjust the room temperature. The low-pressure gaseous refrigerant is sucked into the compressor and compressed into a high-temperature and high-pressure gas; then, the gaseous refrigerant flows to the outdoor condenser, and gradually condenses into a high-pressure liquid during the process of heat dissipation to the outside; then, the pressure is reduced through the throttling device ( At th...

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

[0004] Furthermore, as disclosed in the Chinese patent (authorized notification number CN101714847B), there is an air-conditioning outdoor motor control method that can adaptively operate according to the ambient temperature and the frequency state of the compressor. The detailed regulations of the high speed make the whole machine prone to noise and vibration during the process of starting to high speed, which affects the comfort of the user
