A parking air conditioner voltage detection control method and parking air conditioner

Abstract

Power on the parking air conditioner, determine whether the power supply voltage meets the operating conditions; if so, sample the ambient temperature inside the car; determine whether the ambient temperature inside the car meets the starting conditions; if so, output a starting control signal to the outdoor drive module, compress start the machine; determine the temperature gear range to which the ambient temperature in the car belongs, and output the corresponding gear control signal, and the compressor will work according to the frequency corresponding to the gear control signal; determine whether the shutdown condition is met and whether the power supply voltage meets the protection condition; if If the condition is met, the shutdown control signal is output to the outdoor drive module, 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, provides good protection for the parking air conditioner, reduces the probability of communication failures, 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 voltage detection and 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....

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.
