搅拌车、电驱空调改造方法及应用Retrofitting methods and applications of mixer trucks and electric-driven air conditioners 技术领域Technical field
本发明涉及搅拌车领域，尤其涉及一种搅拌车、电驱空调改造方法及应用。The present invention relates to the field of mixer trucks, and in particular, to a method and application for retrofitting mixer trucks and electric-driven air conditioners.
背景技术Background technique
搅拌车，指的是混凝土搅拌车，是用来运输建筑用混凝土的专用卡车，这类卡车上通常配备能量回收系统、车载空调和搅拌上装等，其中能量回收系统指的是将浪费掉的比如热能、机械能、光能等，转化为电能储存起来再利用；车载空调用于对搅拌车上的驾驶室进行制冷；搅拌上装用于对混凝土进行持续搅拌的搅拌罐，以免混凝土凝固而无法流出。Mixer truck refers to concrete mixer truck, which is a special truck used to transport concrete for construction. Such trucks are usually equipped with energy recovery systems, on-board air conditioners and mixing tops. The energy recovery system refers to the wasted materials such as Thermal energy, mechanical energy, light energy, etc. are converted into electrical energy and stored for reuse; the vehicle air conditioner is used to cool the cab of the mixer truck; the mixing top is equipped with a mixing tank for continuous mixing of concrete to prevent the concrete from solidifying and being unable to flow out.
传统燃油搅拌车的车载空调和搅拌罐均是由油驱动的，以车载空调为例，所述车载空调包括安装于驾驶室内的蒸发器，以及安装于发动舱内的压缩机和冷凝器等，当驾驶员打开空调后，压缩机的离合片与发动机相连，从而驱动压缩机。而传统燃油搅拌车为了节约油耗、提高驾驶室的舒适度，会进行电驱空调的改造，即通过电池为压缩机提供电能。常规的改造过程如下：The on-board air conditioner and mixing tank of traditional fuel mixer trucks are both driven by oil. Taking the on-board air conditioner as an example, the on-board air conditioner includes an evaporator installed in the cab, as well as a compressor and condenser installed in the engine compartment. When the driver turns on the air conditioner, the clutch plate of the compressor is connected to the engine to drive the compressor. In order to save fuel consumption and improve the comfort of the cab, traditional fuel mixer trucks will be modified with electric air conditioners, that is, batteries will be used to provide electric energy to the compressor. The conventional transformation process is as follows:
采购一套全新的电驱空调装置，包括电池以及空调的室内机、室外机、电驱动压缩机和膨胀阀等，其中室内机安装于驾驶室内部，电池及空调的其他组件安装于驾驶室的顶部或后方。Purchase a new electric-driven air-conditioning device, including batteries, indoor units, outdoor units, electric-driven compressors and expansion valves of the air conditioner. The indoor unit is installed inside the cab, and the battery and other components of the air conditioner are installed inside the cab. Top or rear.
上述改造过程直接舍弃了原有的车载空调系统，没有有效利用原有空调系统中的设备和控制面板，不仅造成改造成本的增加，而且还需要单独设置空调的控制面板或者配置空调遥控器，造成开车状态的驾驶员操作不便，影响行车安全。The above-mentioned transformation process directly abandoned the original vehicle air-conditioning system and did not effectively utilize the equipment and control panels in the original air-conditioning system. This not only increased the cost of transformation, but also required setting up a separate air-conditioning control panel or configuring an air-conditioning remote control, resulting in It is inconvenient for drivers to operate while driving, which affects driving safety.
另外，随着工作时长的增加，电机和电池会产热，当热量过大，则直接影响电机和电池性能，因此需要配备冷却系统，而目前的冷却系统主要通过额外设置的循环水泵、循环水箱、散热器和散热风扇来冷却的，不仅结构庞杂，而且进一步增加了成本。In addition, as the working hours increase, the motor and battery will generate heat. When the heat is too large, it will directly affect the performance of the motor and battery. Therefore, a cooling system is required. The current cooling system mainly uses additional circulating water pumps and circulating water tanks. , radiator and cooling fan for cooling, which not only has a complicated structure, but also further increases the cost.

如图2所示，所述电驱空调改造方法，用于改造燃油搅拌车的原车载空调100’，所述方法包括以下步骤：As shown in Figure 2, the electric-driven air conditioner modification method is used to modify the original vehicle air conditioner 100' of a fuel mixer truck. The method includes the following steps:
(a)断开所述原车载空调100’的一原冷凝器111’和一原压缩机114’，并保留所述原车载空调的一原蒸发器121’；(a) Disconnect an original condenser 111' and an original compressor 114' of the original vehicle air conditioner 100', and retain an original evaporator 121' of the original vehicle air conditioner;
(b)提供一室外集成机110和至少一电驱113，所述室外集成机110包括一冷凝器111和一压缩机114，所述电驱113和所述压缩机114电连接；(b) Provide an outdoor integrated machine 110 and at least one electric drive 113. The outdoor integrated machine 110 includes a condenser 111 and a compressor 114, and the electric drive 113 and the compressor 114 are electrically connected;
(c)直接地安装所述室外集成机110至所述搅拌车上，并将所述原蒸发器121’、所述冷凝器111和所述压缩机114串联以形成空调回路。(c) Directly install the outdoor integrated machine 110 on the mixer truck, and connect the original evaporator 121', the condenser 111 and the compressor 114 in series to form an air conditioning circuit.
所述电驱空调改造方法是在原车载空调100’的基础上进行改造的，舍弃安装在搅拌车不同位置的所述原压缩机114’和所述原冷凝器111’等，保留位于所述驾驶室200内的所述原蒸发器121’，并配备集成有所述冷凝器111和所述压缩机114等的所述室外集成机110，相对于完全重新配置的改造方式来说，有效降低成本，并且无需对所述压缩机114和所述冷凝器111进行逐一安装，只需安装所述室外集成机110一次即可，不仅减少改造工序，还使得改造后的结构更加紧凑，实现减少占地面积，以及便于安装和维护的目的。另外所述压缩机114由所述电驱113提供电能，有效降低油耗。The electric drive air conditioner modification method is based on the original vehicle air conditioner 100', discarding the original compressor 114' and the original condenser 111' installed in different positions of the mixer truck, and retaining the original compressor 114' installed in the driving position. The original evaporator 121' in the room 200 is equipped with the outdoor integrated machine 110 integrated with the condenser 111, the compressor 114, etc., which effectively reduces the cost compared to the complete reconfiguration method. , and there is no need to install the compressor 114 and the condenser 111 one by one, and the outdoor integrated unit 110 only needs to be installed once, which not only reduces the modification process, but also makes the modified structure more compact and reduces the floor space. area, as well as ease of installation and maintenance purposes. In addition, the electric drive 113 provides electric energy to the compressor 114, which effectively reduces fuel consumption.
如图1所示，所述原车载空调100’包括原蒸发器121’、原压缩机114’、原冷凝器111’和原膨胀阀116’，所述原蒸发器121’、所述原压缩机114’、所述原冷凝器111’和所述原膨胀阀116’依次串联，以形成空调回路，并且制冷剂在空调回流中循环流动。As shown in Figure 1, the original vehicle air conditioner 100' includes an original evaporator 121', an original compressor 114', an original condenser 111' and an original expansion valve 116'. The original evaporator 121', the original compressor The machine 114', the original condenser 111' and the original expansion valve 116' are connected in series in sequence to form an air conditioning circuit, and the refrigerant circulates in the air conditioning return flow.
其中所述原蒸发器121’设置在搅拌车的驾驶室200内，而所述原压缩机114’和所述原冷凝器111’散乱设置在发动机室。其工作原理如下：The original evaporator 121' is arranged in the cab 200 of the mixer truck, and the original compressor 114' and the original condenser 111' are scattered in the engine room. Here's how it works:
原压缩机114’将气态的制冷剂从原蒸发器121’中抽出，并将其压入原冷凝器111’，高压气态制冷剂经原冷凝器111’时液化而进行热交换(释放热量)，热量被驾驶室200外的空气带走。高压液态制冷剂经原膨胀阀116’的节流作用而降压，低压液态制冷剂在原蒸发器 121’中气化而进行热交换(吸收热量)，原蒸发器121’附近被冷却的空气通过鼓风机等吹入驾驶室200内。The original compressor 114' extracts the gaseous refrigerant from the original evaporator 121' and presses it into the original condenser 111'. When the high-pressure gaseous refrigerant passes through the original condenser 111', it is liquefied and undergoes heat exchange (releases heat). , the heat is taken away by the air outside the cab 200. The high-pressure liquid refrigerant is depressurized by the throttling effect of the original expansion valve 116'. The low-pressure liquid refrigerant vaporizes in the original evaporator 121' to perform heat exchange (absorb heat). The cooled air near the original evaporator 121' passes through The blower etc. blow into the cab 200.
而本实施例保留设置在所述驾驶室200内的所述原蒸发器121’，并利用所述室外集成机110替换所述原压缩机114’和所述原冷凝器111’等，避免在驾驶室200内额外安装空调室内机，不仅节约成本，减少改造工序，而且便于对所述室外集成机110的各零件进行集中维护和安装。In this embodiment, the original evaporator 121' installed in the cab 200 is retained, and the outdoor integrated machine 110 is used to replace the original compressor 114', the original condenser 111', etc., to avoid Installing an additional air-conditioning indoor unit in the cab 200 not only saves costs and reduces modification procedures, but also facilitates centralized maintenance and installation of various parts of the outdoor integrated unit 110 .
参考图2，在所述步骤(a)中，还可保留所述原车载空调100’的原控制面板，以在所述步骤(c)中，将所述压缩机114和所述原控制面板电连接，以使所述原控制面板能够控制所述压缩机114工作。避免单独设置空调的控制板或者配置空调遥控器，而增加成本，并且操控更加安全。Referring to Figure 2, in step (a), the original control panel of the original vehicle air conditioner 100' can also be retained, so that in step (c), the compressor 114 and the original control panel Electrical connection, so that the original control panel can control the operation of the compressor 114. Avoid setting up a separate air conditioner control panel or configuring an air conditioner remote control, which increases costs, and makes the operation safer.
继续参考图2，在所述步骤(a)中，可拆除所述原车载空调100’的原膨胀阀116’，以在所述步骤(b)中，所述室外集成机110还包括膨胀阀116’，并且所述原蒸发器121’、所述膨胀阀116’、所述冷凝器111和所述压缩机114串联以形成空调回路。Continuing to refer to Figure 2, in step (a), the original expansion valve 116' of the original vehicle air conditioner 100' can be removed, so that in step (b), the outdoor integrated machine 110 further includes an expansion valve. 116', and the original evaporator 121', the expansion valve 116', the condenser 111 and the compressor 114 are connected in series to form an air conditioning circuit.
如图2和图3所示，所述室外集成机110还包括至少一换热器112，所述换热器112包括相互分隔且能够换热的至少一第一换热部1121和至少一第二换热部1122，进而所述步骤(b)包括：As shown in Figures 2 and 3, the outdoor integrated machine 110 further includes at least one heat exchanger 112. The heat exchanger 112 includes at least a first heat exchange part 1121 and at least a first heat exchange part 1121 that are separated from each other and capable of heat exchange. Second heat exchange part 1122, and step (b) includes:
(b1)将所述第一换热部1121、所述冷凝器111和所述压缩机114串联，以使第一冷媒能够在所述第一换热部1121和所述冷凝器111之间循环流动；(b1) Connect the first heat exchange part 1121, the condenser 111 and the compressor 114 in series so that the first refrigerant can circulate between the first heat exchange part 1121 and the condenser 111 flow;
(b3)串联所述电驱113和所述第二换热部1122，以使第二冷媒能够在所述电驱113和所述第二换热部1122之间循环流动。(b3) The electric drive 113 and the second heat exchange part 1122 are connected in series, so that the second refrigerant can circulate between the electric drive 113 and the second heat exchange part 1122.
所述第一冷媒可以为制冷剂，可循环流动于所述第一换热部1121，以及所述原蒸发器121’和所述冷凝器111之间形成的空调回路。所述第二冷媒可以为制冷剂等，可循环流动于所述第二换热部1122和所述电驱113之间，由于所述第一换热部1121和所述第二换热部1122能够换热，因此所述电驱113利用了所述第二冷媒和所述第一冷媒换热，以进行冷却降温，可见所述电驱113是利用所述空调的制冷量进行冷却的，因此无需增设额外且复杂的冷却结构，例如散热器、散热风扇、循环水泵和循环水箱等组成的冷却结构，简化结构，进一步降低使用成本。The first refrigerant may be a refrigerant, which may circulate in the first heat exchange part 1121 and the air conditioning circuit formed between the original evaporator 121' and the condenser 111. The second refrigerant may be refrigerant, etc., and may circulate between the second heat exchange part 1122 and the electric drive 113. Since the first heat exchange part 1121 and the second heat exchange part 1122 It can exchange heat, so the electric drive 113 uses the second refrigerant and the first refrigerant to exchange heat for cooling. It can be seen that the electric drive 113 uses the cooling capacity of the air conditioner for cooling, so There is no need to add additional and complex cooling structures, such as cooling structures composed of radiators, cooling fans, circulating water pumps, and circulating water tanks, simplifying the structure and further reducing usage costs.
参考图3，所述第一换热部1121和所述第二换热部1122可以为管道等，两者并排设置，并且两者相互分隔，避免所述第一冷媒和所述第二冷媒直接接触。利用所述第一换热部1121和所述第二换热部1122相互接触，或者在两者之间设置导热材料，以实现所述第一冷媒和所 述第二冷媒的换热效果。Referring to FIG. 3 , the first heat exchange part 1121 and the second heat exchange part 1122 may be pipes, etc., both of which are arranged side by side and separated from each other to avoid direct contact between the first refrigerant and the second refrigerant. touch. The first heat exchange part 1121 and the second heat exchange part 1122 are in contact with each other, or a thermal conductive material is provided between them, so as to achieve the heat exchange effect of the first refrigerant and the second refrigerant.
所述电驱113可具有电驱本体和设置在电驱本体上的冷却结构，所述第二冷媒在所述冷却结构内循环流动，以对所述电驱本体进行冷却。The electric drive 113 may have an electric drive body and a cooling structure provided on the electric drive body, and the second refrigerant circulates in the cooling structure to cool the electric drive body.
以盘式电机和盘式发电机为例，所述冷却结构可以为开设在所述电机壳体内的冷却通道，当所述第二冷媒在所述冷却通道内循环流动时，可带走电机的绕组等发热元件产生的热量。当然所述冷却结构可以是与电机壳体接触的管道。Taking disc motors and disc generators as examples, the cooling structure may be a cooling channel opened in the motor housing. When the second refrigerant circulates in the cooling channel, it can take away the motor. The heat generated by heating elements such as windings. Of course, the cooling structure may be a pipe in contact with the motor housing.
以电池包为例，所述冷却结构可以为与电池包接触的管道，所述管道可螺旋缠绕于所述电池包外部，以增加两者的接触面积，提升换热效率。Taking the battery pack as an example, the cooling structure can be a pipe in contact with the battery pack.
