Parking air conditioner voltage detection control method and parking air conditioner

Abstract

The invention discloses a parking air conditioner voltage detection control method and meanwhile further discloses a parking air conditioner. The parking air conditioner voltage detection control method comprises the steps that the parking air conditioner is powered on, whether the voltage of a power supply meets the operation condition or not is judged, and if the voltage of the power supply meets the operation condition, the in-vehicle environment temperature is sampled; whether the in-vehicle environment temperature meets the starting condition or not is judged, if the in-vehicle environment temperature meets the starting condition, a starting control signal is output to an outdoor driving module, and a compressor is started; the temperature gear interval to which the in-vehicle environment temperature belongs is judged, a corresponding gear control signal is output, and the compressor works according to the frequency corresponding to the gear control signal; and whether the shutdown condition is met or not and whether the voltage of the power supply meets the protection condition or not are judged, if the shutdown condition is met and the voltage of the power supply meets the protection condition, a shutdown control signal is output to the outdoor driving module, and the outdoor driving module drives the compressor to be shut down. According to the parking air conditioner voltage detection control method, the cruising ability of the parking air conditioner is improved, the parking air conditioner is well protected, the probability of communication failure is decreased,and the practicability of the parking air conditioner is improved.

Description

Technical field [0001] The invention relates to the technical field of air conditioning equipment, and in particular to a parking air conditioner voltage detection and control method and a parking air conditioner. Background technique [0002] Parking air conditioner refers to the air conditioner used when parking and waiting and resting. It is usually installed on trucks and vans and can be used by drivers during long-distance driving. Traditional parking air conditioners include the following forms: the first is to drive the compressor to run through a diesel generator, and the compressor drives the refrigerant to circulate in a sealed refrigeration system. The diesel generator uses water as the cooling medium; One still uses diesel generators to drive the compressor, but uses flowing air as the cooling medium; the third one uses gasoline generators to drive the compressor; the fourth one uses DC power to drive the compressor. [0003] It is not difficult to see that in the firs...

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.
