Problems solved by technology

[0003] Since most of the heat of the motor reaches the heat dissipation structure through heat conduction, the cooling area is increased and then the heat is dissipated in the form of air convection. However, the existing defrosting device setting method cannot effectively recover a larger part of the heat, so Poor defrosting effect

Embodiment Construction

[0032] Example of air conditioning system for vehicles

[0033] see Figure 1 to Figure 3 , the vehicle of the present embodiment is a passenger car, and from the direction of the head and tail of the passenger car, the rear of the passenger car is provided with a motor cabin 500 and an air-conditioning cabin 100 in sequence, and the first heat exchanger 12 of the air-conditioning system is arranged in the air-conditioning cabin 100, The motor 5 of the passenger car is arranged in the motor compartment 500, and the motor 5 is the main drive motor of the passenger car. Wherein, the first heat exchanger 12 is the outdoor side heat exchanger of the present invention, the outdoor side is a relative concept of the indoor side, and the indoor side refers to the space that needs to achieve cooling or heating effects, and the outdoor side is not the outside of the bus as a whole, but Refers to the outside of the space that needs to achieve cooling or heating effects.

Abstract

The invention provides a defrosting device, a vehicle, a vehicle air conditioning system and a control method of the vehicle air conditioning system, the defrosting device of the vehicle air conditioning system comprises an outdoor heat exchanger of the air conditioning system and a motor of the vehicle, and the outdoor heat exchanger and the motor are arranged in an air conditioning cabin and a motor cabin of the vehicle respectively; the defrosting device further comprises a ventilation structure arranged between the air conditioner cabin and the motor cabin. The air-conditioning system comprises a defrosting device, a water pump and a water-cooling heat dissipation pipe, the vehicle comprises the air-conditioning system, and the control method comprises the steps that when the air-conditioning system operates in a heating mode and first detection temperature data of the first heat exchanger is lower than a first preset value, the ventilation structure is opened, and the rotating speed of the draught fan is increased. The control method further comprises the steps of starting the water pump and the second throttling device when the air conditioning system operates in a refrigeration mode and second detection temperature data of the motor is higher than a second preset value. The recovery rate of heat generated by the motor can be increased, and defrosting is further facilitated.

Description

technical field [0001] The invention relates to the technical field of air-conditioning equipment, in particular to a defrosting device of an air-conditioning system of a vehicle, an air-conditioning system of a vehicle, a control method thereof, and a vehicle. Background technique [0002] The main drive motor of a vehicle such as a car will generate a lot of heat when it is in operation. An existing vehicle air conditioning system is controlled by installing a heat exchange pipe at the motor, and the outlet of the heat exchange pipe is connected to the heat pump of the vehicle through the pipeline. system, this setting recovers the heat generated by the electric motor and uses it to defrost the exterior condenser. [0003] Because most of the heat of the motor reaches the heat dissipation structure through heat conduction, and the cooling area is increased to dissipate heat in the form of air convection. However, the existing defrosting device setting method cannot effecti...
