具体实施方式detailed description
当室内面积较大时，若采用一台空调器进行制冷或制热，换热效果往往较差；而采用多台空调器同时进行换热，成本较高，并且运行时的电负荷也较大。因此相关技术中采用一台空调外机带动并联设置的多台空调内机的方式进行换热。但是，本申请的发明人发现，采用上述方案依然存在室内换热不均匀的问题。When the indoor area is large, if one air conditioner is used for cooling or heating, the heat exchange effect is often poor; while multiple air conditioners are used for heat exchange at the same time, the cost is high, and the electrical load during operation is also large . Therefore, in the related art, one air conditioner external unit drives multiple air conditioner internal units connected in parallel to perform heat exchange.

图3是本申请一实施例提供的空调器的结构简图。如图3所示，本实施例提供一种空调器，包括空调外机10以及与空调外机10相连的多台空调内机300，每一台空调内机300均设有与其对应的测温装置(图中未示出)。Fig. 3 is a schematic structural diagram of an air conditioner provided by an embodiment of the present application. As shown in Figure 3, the present embodiment provides an air conditioner, including an air conditioner external unit 10 and a plurality of air conditioner internal units 300 connected to the air conditioner external unit 10, each air conditioner internal unit 300 is provided with a corresponding temperature measurement device (not shown in the figure).
本实施例的空调外机10内设有压缩机101、冷凝器102和四通阀；压缩机101、冷凝器102和四通阀串联连接。空调内机300内设有蒸发器301、电磁阀302和止回阀303；电磁阀302和止回阀303分别串联连接在蒸发器301的两侧，可以通过控制电磁阀302的开度来控制进入蒸发器301内的冷媒的流量；止回阀303可以防止不同工作压力的蒸发器301出液串流。空调器还包括节流装置400，节流装置400例如可以是毛细管组件，毛细管组件中设有流动的制冷剂，节流装置400连接蒸发器301和冷凝器102。测温装置可以是安装在空调内机300上的室温传感器；或者测温装置可以是独立安装在室内的装置，例如，测温装置包括设置在空调内机四周的多个测温计，每一个测温计到空调内机的出风口的距离相同或不同，测温装置测得的温度为多个测温计测得的温度的平均值或加权平均值。A compressor 101 , a condenser 102 and a four-way valve are provided inside the air-conditioner external unit 10 of this embodiment; the compressor 101 , the condenser 102 and the four-way valve are connected in series. An evaporator 301, a solenoid valve 302 and a check valve 303 are installed in the air conditioner 300; The flow rate of the refrigerant entering the evaporator 301; the check valve 303 can prevent the evaporator 301 with different working pressures from flowing out. The air conditioner further includes a throttling device 400 . The throttling device 400 may be, for example, a capillary tube assembly in which a flowing refrigerant is arranged. The throttling device 400 is connected to the evaporator 301 and the condenser 102 . The temperature measuring device can be a room temperature sensor installed on the air conditioner internal unit 300; or the temperature measuring device can be a device installed indoors independently, for example, the temperature measuring device includes a plurality of thermometers arranged around the air conditioner internal unit, each The distances from the thermometers to the air outlet of the air conditioner indoor unit are the same or different, and the temperature measured by the temperature measuring device is the average or weighted average of the temperatures measured by multiple thermometers.
空调器的制冷过程为：压缩机101将气态的制冷剂压缩为高温高压的气态制冷剂，然后送到冷凝器102散热后成为常温高压的液态制冷剂，液态制冷剂通过节流装置400进入蒸发器301，由于制冷剂从节流装置400到达蒸发器301后空间突然增大，制冷剂受到的压力减小，液态的制冷剂 就会汽化，变成气态低温的制冷剂，从而吸收大量的热量，蒸发器301就会变冷，空调内机的贯流风扇引导室内的空气从蒸发器301中吹过，从而使空调内机吹出冷风。空调器的制热过程与上述制冷过程的原理相同，只不过利用四通阀使制冷剂在冷凝器102与蒸发器301的流动方向与制冷时相反，从而实现制热的目的。The refrigeration process of the air conditioner is as follows: the compressor 101 compresses the gaseous refrigerant into a high-temperature and high-pressure gaseous refrigerant, and then sends it to the condenser 102 to dissipate heat and become a liquid refrigerant at room temperature and high pressure. The liquid refrigerant enters the evaporation through the throttling device 400 Since the refrigerant reaches the evaporator 301 from the throttling device 400, the space suddenly increases, the pressure on the refrigerant decreases, and the liquid refrigerant will vaporize and become a gaseous low-temperature refrigerant, thereby absorbing a large amount of heat , the evaporator 301 will become colder, and the cross-flow fan of the air conditioner inner unit guides the indoor air to blow through the evaporator 301, so that the air conditioner inner unit blows out cold wind. The principle of the heating process of the air conditioner is the same as that of the above-mentioned cooling process, except that the four-way valve is used to make the flow direction of the refrigerant in the condenser 102 and the evaporator 301 opposite to that of cooling, so as to achieve the purpose of heating.

The controller 200 receives the temperature measured by the multiple temperature measuring devices and controls each air conditioner internal unit 300 allocated traffic.
本实施例中控制器接收多个测温装置测得的温度并控制每一台空调内机300分配到的流量的具体方法如上述实施例中所述，本实施例在此不在赘述。In this embodiment, the specific method for the controller to receive the temperature measured by multiple temperature measuring devices and control the flow allocated to each air-conditioning indoor unit 300 is as described in the above-mentioned embodiment, and will not be repeated in this embodiment.
