Parking air conditioner controlling method and parking air conditioner

Abstract

The invention relates to a parking air conditioner controlling method. The parking air conditioner controlling method comprises the following steps that an indoor control module samples environment temperature in a vehicle; the indoor control module judges whether the environment temperature in the vehicle meets air conditioner switching on condition or not; if yes, the indoor control module outputs an air conditioner switching on control signal to an outdoor driving module through a first signal route, and the outdoor driving module drives a compressor to start; the indoor control module continues judging a temperature position interval to which the environment temperature in the vehicle belongs, and outputs a corresponding position control signal to the outdoor driving module through a second signal route, and the compressor is driven to work according to the frequency corresponding to the position control signal; the indoor control module judges whether the environment temperature in the vehicle meet air conditioner switching off condition or not; and if yes, the indoor control module outputs an air conditioner switching off control signal to the outdoor driving module through the first signal route, and the outdoor driving module drives the compressor to switch off. Besides, the invention discloses a parking air conditioner. The endurance capability of the parking air conditioner is improved, the probability of generating communication failures is reduced, and the practicality of the parking air conditioner is improved.

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.
