Problems solved by technology

[0012] In the prior art, if the compressor can be started in a low temperature environment, an independent heating device must be added to the compressor, and the heat generated by the heating device can improve the condition of the refrigerant or compressor oil inside the compressor, but adding a heating device or Retrofitting the compressor will further increase the production and use cost of the compressor
On the other hand, heating the device while in use also consumes a lot of energy

Embodiment Construction

[0024] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0025] image 3 It is a schematic circuit diagram of the drive structure of the swing fan motor of the indoor unit of the air conditioner of the present invention.

[0026] like image 3 As shown, the low-temperature startup method of an air conditioner compressor of the present invention includes the following stages: a first stage of detecting whether the compressor is running; if the compressor is in a non-operating state, a first stage of sensing the piping temperature through indoor and outdoor temperature sensors Second stage; if the indoor piping temperature sensed in the second stage is lower than the first temperature A and the outdoor piping temperature is less than the second temperature B, it means that the air conditioner is in a low temperature environment, and the indoor and outdoor temperatures are both low, and the steps to start at no...

Abstract

The invention relates to a method for starting a compressor of an air conditioner at low temperature, which comprises the following steps: detecting whether the compressor is running or not; if the compressor does not run, sensing a piping temperature; if an indoor piping temperature is lower than a first temperature A and an outdoor piping temperature is lower than a second temperature B, preparing to preheat the compressor; rotating a rotor to a scheduled starting position; preheating coolants and compressor oil in the compressor through coils of a motor of the compressor; starting the compressor to run; detecting whether the compressor is running normally or not; if the compressor runs normally, sensing the piping temperature; and if the indoor piping temperature is greater than a third temperature or the outdoor piping temperature is greater than a fourth temperature D, stopping preheating the compressor. The method enables the compressor oil in an outdoor piping to restore to a normal temperature state, and reduces the viscosity of the compressor oil, so that the compressor is easier to start.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a low temperature start-up method for the compressor of an air conditioner, which preheats the compressor through the current heating effect generated by the coil of the compressor in a low temperature state so that the compressor can start normally. Background technique [0002] An air conditioner is an indoor climate adjustment device, the main components include a refrigeration cycle system including a compressor, a condenser, a throttling device and an evaporator, and an air cycle system including a blower, air ducts, and air inlets and outlets. The air conditioner realizes the functions of cooling or heating and dehumidification by drawing indoor air, changing its temperature by the evaporator and condenser of the heat exchange device, and then discharging it back into the room, so as to provide people with a fresh and comfortable indoor air environment.
