A kind of parking air conditioning control method and parking air conditioning

Abstract

Parking air conditioning control method: the indoor control module samples the ambient temperature inside the vehicle; the indoor control module determines whether the ambient temperature in the vehicle meets the start-up conditions; if so, the indoor control module outputs a start-up control signal to the outdoor drive module through the first signal path, and the outdoor drive The module drives the compressor to start; the indoor control module continues to determine the temperature gear range to which the ambient temperature in the car belongs, and outputs the corresponding gear control signal to the outdoor drive module through the second signal path, and drives the compressor according to the corresponding gear range of the gear control signal. frequency operation; the indoor control module determines whether the ambient temperature in the vehicle meets the shutdown condition; if so, the indoor control module outputs a shutdown control signal to the outdoor drive module through the first signal path, and the outdoor drive module drives the compressor to stop. Also discloses a parking air conditioner at the same time. The invention improves the battery life of the parking air conditioner, reduces the probability of communication failure, and improves the practicability of the parking air conditioner.

Description

technical field [0001] The invention relates to the technical field of air conditioning equipment, in particular to a parking air conditioner control method and a parking air conditioner. Background technique [0002] Parking air conditioner refers to the air conditioner used when parking, waiting and resting. It is usually installed on trucks and vans, and drivers can use it during long-distance driving. Traditional parking air conditioners include the following forms: the first is to drive the compressor to run through the diesel generator, and further drive the refrigerant to circulate in the sealed refrigeration system through the compressor, and the diesel generator uses water as the cooling medium; the second The first type also uses a diesel generator to drive the compressor, but uses flowing air as the cooling medium; the third type uses a gasoline generator to drive the compressor; the fourth type uses a DC power supply to drive the compressor. [0003] It is not d...

AI Technical Summary

Problems solved by technology

On the one hand, it increases the control cost of the equipment. On the other hand, due to the unstable operating environment of the parking air conditioner, the control module may need to work in a humid environment for a long time, and the possibility of communication failure is very high.

Once a communication failure occurs, a complex process is required in the prior art to determine the failure point and repair it, and the actual use effect is not good.
