In addition, the function of the fixing part 217 is to restrict the refrigerant connection pipe 216, the condensate water connection pipe 214 and the circuit connection wire 215 so that they will not be loosened or knotted during transportation or installation.

Next, refer to Fig. 8 and Fig. 9, Fig. 8 is a control principle diagram of the detachable and combined air-conditioning unit of the present invention; Fig. 9 is a schematic diagram of the refrigerant pipeline structure of the detachable and combined air-conditioning unit of the present invention. As shown in Figure 8, the air conditioning unit includes a temperature detection module 27 and an electronic control valve 28 in addition to the control module 13. The temperature detection module 27 detects the actual temperature in the room during the operation of the air conditioning unit; the control module 13 is used to obtain the temperature The detection module 27 detects the indoor temperature, and sends a control instruction according to the comparison between the indoor temperature and the set temperature; the electronically controlled valve 28 is used to open and close the refrigerant entering and exiting the indoor heat exchanger of the air conditioner 1 according to the control instruction. As shown in Figure 9, specifically, the electric control valve 28 is set on the connecting pipeline between the first refrigerant pipe joint 113 and the indoor heat exchanger and the second refrigerant pipe joint 163 and the indoor heat exchanger, by closing and opening the electric control valve 28. Capable of blocking and conducting the flow of refrigerant into and/or out of the indoor heat exchanger. In the actual working process, the air-conditioning unit is first turned on, and the air-conditioning unit performs cooling or heating at the maximum power and maximum wind speed. After running for a period of time, the actual indoor temperature is obtained through the temperature detection module 27, and the detection result is sent to the control module 13 The control module 13 sends a control command according to the difference between the actual temperature and the set temperature, thereby opening and closing the electronically controlled valve, which can effectively control the flow of refrigerant into and out of the indoor heat exchanger.

Specifically, when the indoor temperature has a larger gap than the preset temperature, it indicates that the load of the air-conditioning unit is too large, and the control module 13 sends an instruction to remind the user that the air-conditioner 1 needs to be added. After receiving the instruction, the user turns off the air-conditioning unit, And install an air conditioner 1, start the air conditioner unit again, and perform cooling or heating with the maximum power and maximum air volume. After a period of time, if the indoor temperature is close to the set temperature, it will operate normally; Reach the preset temperature; when the indoor temperature can quickly approach the preset temperature, it indicates that the power of the air conditioning unit is sufficient to meet the predetermined requirements, and the temperature detection module 27 transmits the indoor temperature information to the control module 13, and the control module 13 reduces the speed of the compressor And close the electric control valve 28 of an air conditioner 1, block the refrigerant flowing into and/or flow out of the indoor heat exchanger, make the air conditioner 1 stop working, and be in a standby state. Next, repeatedly detect the difference between the indoor temperature and the predetermined temperature. If the cooling or heating efficiency output by the air conditioner 1 is still too large, continue to turn off another air conditioner 1 until the cooling or heating efficiency of the air conditioning unit can reach the predetermined temperature. , in order to maintain the normal working condition of the set temperature. Furthermore, when the indoor conditions that affect the temperature suddenly change, the actual temperature is quite different from the set temperature, and it is necessary to increase the cooling or heating capacity. At this time, the speed of the compressor is increased, and the electronically controlled valve of the closed air conditioner 1 is opened. 28. The standby air conditioner starts to work, the indoor temperature quickly reaches the set value, and the indoor temperature can be maintained near the predetermined temperature in time. Preferably, the electronic control valve 28 is an electronic expansion valve, and the temperature detection module 27 is a thermistor temperature sensor, although the electronic expansion valve and the thermistor temperature sensor are used as the preferred implementation of the electronic control valve 28 and the temperature detection module 27 above. way, but it is obvious that it can also be replaced by other ways that can realize the above functions. In addition, the command issued by the control module 13 to prompt the user to increase or decrease the air conditioner 1 can be displayed on the display screen of each air conditioner 1, and the display screen of each air conditioner 1 can provide the operating wind speed, running mode, operating temperature, and instructions to increase or decrease the number of air conditioners 1 . Further, the user can also connect the mobile phone to the air-conditioning unit, receive instructions from the control module 13 through the mobile phone app, and make appropriate adjustments to the air-conditioning unit according to the instructions. In addition, the remote controller can also receive instructions determined by the control module 13, so that most users can more easily understand the operating conditions of the air-conditioning unit, and then make appropriate adjustments to the air-conditioning unit.

Therefore, the temperature detection module 27 detects the indoor temperature, the control module 13 judges whether the power of the air conditioner unit can achieve the predetermined temperature, and controls the opening and closing of the electronically controlled valve, so that the user can select an air conditioner unit with an appropriate power according to the actual situation, avoiding the air conditioner unit. Poor actual work and the issue of energy wasted by the air conditioning unit.

Furthermore, when users choose air conditioners, they choose the number of air conditioners according to the size of the space. When the indoor area is 10-15 square meters, they can choose 1P air conditioners; when the room area is 16-20 square meters, A 1.5P air conditioner can be selected; therefore, according to the air conditioner 1 provided by the present invention, the number of horses of each air conditioner 1 can be set to 0.5P or 1P, and the user can adjust the air conditioner according to the indoor area or other requirements for temperature. 1 are combined to complete an air conditioning unit that meets the user's requirements.

In addition, when using air conditioners in multiple spaces, users do not need to install air conditioners of the corresponding number in all rooms. They can decide whether to install air conditioners according to the room utilization rate. Only the air conditioner base 2 needs to be installed in the room. When the air conditioner is needed, the air conditioners in other rooms can be moved to combine and split for use, so as to improve the utilization rate of the air conditioner and save the purchase cost of the user's air conditioner. In addition, the idle air conditioner 1 can also be removed and placed in a locker such as a cabinet, saving more space indoors. In addition, in the spring, autumn and winter seasons in the north, the air conditioner can be disconnected from the quick-change connector, and can be stored in an empty cabinet like clothes, leaving more space in the room and making full use of the interior space.

So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings, but those skilled in the art will easily understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of the present invention.
