Problems solved by technology

[0002] The traditional automotive air conditioner control compressor pull-in is to connect a temperature-sensing package in series in the compressor circuit, and the temperature-sensing probe goes deep into the evaporator. When the temperature of the evaporator is too low, the circuit is disconnected and the compressor does not pull-in (no cooling); However, due to the fixed opening and closing range of the temperature sensing package used in the series circuit (for example, opening and closing when it is less than 4°C, and closing when it is greater than 8°C), the system cannot adapt to different air volumes.
[0003] Therefore, if a large start-stop temperature difference is set, the compressor’s pull-in time is normal when the air volume is small, but when the air volume is large, the compressor stops for a long time, and the cooling effect is not good; if a small start-stop temperature difference is set, When the air volume is large, the compressor starts and stops normally, but when the air volume is small, it starts and stops frequently
In order to have a better air-conditioning effect, the manufacturer usually sets a small start-stop temperature difference, but once the user reduces the air volume, the frequent start-stop of the compressor will seriously affect the service life

Abstract

The invention provides a controller for preventing frequent pull-in of an automobile air conditioning compressor. The controller for preventing frequent pull-in of the automobile air conditioning compressor comprises a collection module, a control module, a transmission module and a driving module. The collection module comprises a digital temperature sensor for collecting environment temperatureand air volume in an automobile, and the control module is used for identifying and judging the information collected by the collection module and issuing operation instructions. The transmission module is used for transmitting data, and the driving module comprises the compressor and a blower for controlling the operation of parts after receiving the operation instructions. The invention furtherprovides a control method for controller for preventing frequent pull-in of the automobile air conditioning compressor. The digital sensor is arranged on the surface of an evaporator, so that an automobile air conditioning user can keep a certain temperature of an air outlet while different air volume is opened, and the best working state, 50 seconds for pull-in and 10 seconds for disconnecting inone minute, of the compressor is kept. The frequent pull-in of compressor is effectively prevented, and the life of the air conditioning is prolonged.
