Vehicle air conditioning system and its condensed water reuse system

Abstract

The present invention relates to the technical field of vehicles, and provides a vehicle air-conditioning system and its condensed water reuse system, comprising: a condensed water delivery pipeline, and the condensed water flowing into the condensed water delivery pipeline flows through a first electromagnetic valve to a first heat exchange device for heat exchange. Heat exchange to reduce the temperature inside the vehicle, or flow through the first outlet of the first three-way solenoid valve to the second heat exchange device for heat exchange to reduce the temperature of condensed water; the condensed water feedback pipeline connects the second heat exchange device with the first A heat exchange device; a temperature detection device for detecting the temperature of condensed water; and a control device. Moreover, the control device is configured to: when the temperature of the condensed water is less than or equal to the set temperature threshold, control the first three-way solenoid valve and the first solenoid valve so that the condensed water enters the first heat exchange device for heat exchange and cooling, Otherwise, the condensed water enters the second heat exchange device for heat exchange and then flows to the first heat exchange device through the condensed water feedback pipeline. The invention solves the problem that heat exchange cannot be performed due to insufficient water temperature of condensed water.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle air conditioning system and a condensed water reuse system thereof. Background technique [0002] Vehicle air conditioning system is a system that provides customers with functions such as cooling, heating, defrosting and defogging. When the air conditioning system is refrigerating, its condenser often produces condensed water, which is then discharged out of the vehicle. Due to the low temperature of the condensed water (6°C-10°C), various schemes have been adopted in the prior art to reuse the condensed water to cool other components of the vehicle thermal management, so as to improve the vehicle thermal management level. the goal of. [0003] At present, there are mainly the following two secondary utilization schemes of condensed water in the prior art: [0004] 1) Spray the air-conditioning condensate on the air-conditioning condenser to cool down the heat dissi...

Problems solved by technology

For example, for the first solution, the condensate water of the air conditioner becomes longer with the pipeline, and when the temperature reaches the radiator, due to the influence of the pipeline layout and structure, the actual temperature of the condensate water has risen to more than ten or twenty degrees. The cooling effect of the condenser water cannot be exerted, and the temperature of other components will not be lowered, and the temperature may be higher than that of other components, which will bring negative effects on the contrary.

[0008] 2. Condensed water is the water produced by the air on the surface of the air conditioner evaporator due to cooling. The amount of condensed water is related to the humidity of the air and the temperature of the air conditioner. If the air conditioner is relatively dry and the humidity is low, there will be little condensed water. It will reduce the flow rate of condensed water, unable to cool down other radiators, or the cooling effect is poor, resulting in low heat exchange efficiency

[0009] 3. In the prior art, the heat exchanger Chiler is often used to cool the medium in the secondary utilization of condensed water, but the cooling of the Chiler is achieved by consuming the power of the compressor. Simply cooling the medium will consume less power for the compressor. bigger
