Description

一种汽车双空调控制系统及方法 An automotive dual air-conditioning control system and method

技术领域 FIELD

[0001] 本发明涉及汽车的空调技术领域,特别涉及一种汽车双空调控制系统及方法。 [0001] The present invention relates to the field of automotive air conditioning technology, in particular, it relates to a vehicle air conditioning control system and method for double.

背景技术 Background technique

[0002] 汽车空调系统用于实现对车厢内空气进行制冷、加热、换气和空气净化,它可以为乘车人员提供舒适的乘车环境,因此人们对空调系统的性能要求越来越高。 [0002] automotive air conditioning system for implementing the vehicle interior air for cooling, heating, ventilation and air purification, it can provide a comfortable environment for the passenger car, so people performance requirements for air-conditioning systems have become increasingly demanding.

[0003] 目前轻客类车型,部分双空调系统采用的两个蒸发器和一个冷凝器的结构方案, 艮P “双蒸单冷”系统。 [0003] Currently light passenger vehicle type, two structural scheme and a condenser evaporator air conditioning system uses a double portion, Gen P "single double distilled cold" systems.

[0004] 在双空调系统中,为了实现前、后蒸发器的独立控制,配置有两个电磁阀,客户可以根据需要分别控制两个电磁阀,以达到分别控制前、后蒸发器的目的,具体空调系统的循环图可参照图1所示。 [0004] In the double air-conditioning system, in order to realize the front, the rear evaporator independent control, two solenoid valves are disposed, the customer can control two solenoid valves as required to achieve the purpose of respectively controlling the front, the rear evaporator, FIG particular cycle air conditioning system 1 may be shown with reference to FIG.

[0005] 在双空调系统中,客户单独使用后空调而不开启前空调的情况十分少见,因此双空调系统中大多在前空调的制冷回路里不添加电磁阀,而单独在后空调的制冷回路中添加电磁阀,用来实现对后空调的单独控制,具体空调系统的循环图可参照图2所示。 [0005] In the double air-conditioning system, a client without using a separate air after the air conditioner is turned on before the case is very rare, so the air conditioning system mostly double solenoid valve without the addition of air conditioning refrigeration circuit in the former, while a separate refrigerant circuit after the air conditioner adding a solenoid valve for realizing individual control of the air conditioner, the air conditioning system in particular cyclic graph may be shown with reference to FIG.

[0006] 图1与图2所示的两种双空调系统的布置方式,均可以满足整车在温带地区的制冷需求,但是无法满足高温区域整车空调系统超大制冷量的需求。 [0006] FIG. 1 arrangement of Two Kinds of the air conditioning system shown in FIG. 2, each vehicle to meet the cooling demand in temperate regions, but can not meet the large cooling capacity of the air conditioning system of the vehicle needs a high temperature region. 因为当整车只有一个冷凝器的时候,通常该冷凝器与水箱、中冷器等一体布置于发动机舱内的发动机前端,如果系统为了应付高温地区超大制冷量的需求需要增大冷凝器芯体面积,然而受发动机舱体内的空间限制,增大该冷凝器芯体的换热面积却是比较困难的。 Because when the vehicle is only when a condenser, the condenser and the tank are usually, like intercooler integrally disposed in an engine compartment in the front end of the engine, if the system in order to meet the large demand for cooling capacity required to increase high temperature area of ​​the condenser core member area, but within the engine compartment space is limited, increasing the heat transfer area of ​​the condenser core is difficult.

[0007] 在双空调系统中,会有前、后空调不是同时打开使用的情况发生,在这种情况下, 不开启的空调循环回路中,制冷剂还会在该回路的蒸发器中循环,会导致未蒸发完全的液态制冷剂进入压缩机,此种情况会造成压缩机的损坏。 [0007] In the double air-conditioning system, the front there, the air conditioner is not used at the same time to open the case occurs, in this case, the air conditioning cycle is not open circuit, the refrigerant will circulate in the loop in the evaporator, lead to a complete unevaporated liquid refrigerant into the compressor, such a situation may cause damage to the compressor.

[0008] 图1所示的双空调系统中,为了实现前、后蒸发器的独立控制,在前、后空调回路里均配置有电磁阀,但是在车辆空调系统的实际操作情况中,前空调不开启而单独开启后空调的情况十分少见,因此前空调回路上的电磁阀就有些浪费。 Dual air conditioning system shown in FIG. 1 [0008] In order to achieve before, independent control of the evaporator, front and rear air-conditioning circuit is arranged in each solenoid valve, but in the actual operation of the vehicle air conditioning system, air conditioning before after open the case alone without the open air is very rare, so the solenoid valve before the air conditioning back on the road would be wasteful. 整车中电磁阀的布置需要一定的空间,且电磁阀的成本也比较高。 A solenoid valve disposed in the vehicle requires a certain space, and cost of the solenoid valve is relatively high.

[0009] 图2所示的双空调系统中,可以实现不开启后空调而单独开启前空调,也符合实际整车双空调操作的情况,双空调系统实际操作的过程中,经常出现驾驶员和副驾驶需要开启前空调,而此时后排无乘客不需要开启后空调,因此在后空调的回路中配置的电磁阀就有些浪费。 [0009] bis conditioning system shown in Figure 2, may be implemented without the open air before the air conditioning is turned on individually, dual in line with the actual vehicle air conditioning operation, the actual operation of the dual air conditioning system, often the driver and copilot need to turn on the air conditioning before, but this time without the rear passengers do not need the open air, so a solenoid valve arrangement in the air conditioning circuit would be wasteful.

[0043] 需要说明的是,与现有技术不同的是,本发明实施例未采用电磁阀,并且可以通过优化设计空调控制器的逻辑控制程序实现电磁阀的功能,具体地优化方式是:通过软件对空调控制器的逻辑程序进行设定,当前空调开启、压缩机工作、后空调的后鼓风机未开启时,将后空调顶置蒸发器中后鼓风机的端电压设定为设定电压,使后鼓风机输出预先标定设计的最小风量,此时的后鼓风机输出的最小风量工作状态不影响客户的主管感受,且在空调控制器的显示屏上显示后空调为最小风量。 [0043] Note that, unlike the prior art that the embodiments of the present invention does not employ the solenoid valve, and a solenoid valve function can be achieved by optimizing the design of the air conditioning controller logic control program, in particular optimized way: by conditioning software logic controller setting, current air-conditioning turned on, operation of the compressor after the air conditioner when the rear blower is not turned on, the air conditioner after an overhead evaporator blower voltage is set to a set voltage, so that after the minimum air flow output of the blower designed pre-calibrated, minimum air flow operating state at this time is output after the blower does not affect the charge of the customer experience, and the air conditioning controller on the display screen after displaying the minimum air volume air conditioning. 这个逻辑控制程序的作用可以等同于在后蒸发器和压缩机之间增加的电磁阀措施,降低了未蒸发完全的制冷剂进入压缩机而损坏压缩机的风险,且只需要修改空调控制器的逻辑程序即可以实现。 The role of the control logic program may be equivalent to the solenoid valve action between the evaporator and compressor is increased, reducing the risk of not completely evaporated refrigerant entering the compressor and damaging the compressor, and only need to modify the air conditioning controller That logic may be implemented.

[0047]综上所述,本发明实施例中,汽车双空调控制系统具体工作流程如下: [0047] In summary, embodiments of the present invention, particularly automotive dual air conditioning control system works as follows:

[0048]当发动机启动时,驾驶员打开前、后鼓风机、以及压缩机,使压缩机通过发动机驱动开始工作,从压缩机出来的制冷剂通过管路被依次送到底置冷凝器总成、前冷凝器进行冷却,底置冷凝器总成中设置有风扇,前冷凝器设置于发动机散热器前面,靠发动机冷却风扇进行冷却,制冷剂被冷凝成高温高压的液体工质从前冷凝器底部流向储液干燥器,经过过滤、干燥之后,通过管路分别流向前、后膨胀阀,前、后膨胀阀进行了节流、降压控制之后的低温低压的雾状工质再分别进入前、后蒸发器总成,吸收蒸发器总成周围的大量热量汽化成气体,此时,前、后鼓风机不断引导车内的热空气流经蒸发器,热空气被冷却后又被送回到汽车内,汽车内的温度降低。 [0048] When the engine starts, the driver opens the front, rear blower, and a compressor, the compressor is driven by the engine starts to work out the refrigerant from the compressor via line are sequentially sent in the end opposite the condenser assembly, front liquid refrigerant for cooling the condenser, the condenser bottom-mounted cartridge is provided with a fan, a condenser arranged in front of the front of the engine radiator, is cooled by the engine cooling fan, the refrigerant is condensed into high temperature high pressure flows from the front bottom of the condenser reservoir drier, filtered, dried, flows through the front conduit, respectively, the expansion valve, before and after the expansion valve is throttled, the former after low-temperature low-down control mist into the working medium then were evaporated assembly, the absorbent assembly around the evaporation of large amounts of heat vaporized into a gas, at this time, the front and rear blower continue to guide the vehicle through the evaporator of the hot air, the hot air is cooled and then returned to the car, car the temperature in the reduction. 从蒸发器出来的低温低压的气体通过管路又被压缩机吸入,再次压缩,这样就构成了一个完整的双空调系统制冷循环。 Out of the evaporator through line temperature low-pressure gas sucked into the compressor and compressed again, this constitutes a complete dual air conditioning refrigeration cycle system.
