The outlet and inlet of the compressor 1 are connected to the square valve 2. The square room 2 has a first inlet 25, a first outlet 26, a second inlet 27 and a first-outlet 28. The outlet is connected to the first inlet of the square valve 2 0% B3, and the inlet of the compressor 1 is connected to the second outlet 28 of the square valve 2, the first outlet 26 of the square room 2 is connected to a plurality of The inlet ends of the heat exchangers A1, B1, and C1, and the outlet ends of the heat exchangers A1, B1, and C1 are connected to a plurality of expansion devices 44, 45, 46, and each of the expansion devices 44, 45, 46 is connected to a The solenoid valve E4, milk, etc. are collectively connected to an evaporator 8 by the solenoid valves E4, E5, E6, and the evaporator 8 is connected to the second inlet 27 of the square valve 2 to form a circuit. Each of the heat exchangers A1, B1, and C1 is provided with a return air temperature sensor Sa, Sb, Sc on the return air port, and its function is as described above. Preferably, the heat exchangers Al, Bl, and Cl are respectively disposed in different spaces. Alternatively, the present invention may include a plurality of temperature sensors (not shown), and the temperature sensors may be installed in different spaces. Or, the present invention further includes a plurality of temperature sensors (not shown), and the temperature sensors can be installed in the same space. The above embodiments are also applicable to a cold cycle device. The three-pipe temperature sensors S4, S5, and S6 are installed on the pipes from the evaporators Al, Bl, and C1 to the expansion devices 44, 45, and 46. They are also used to detect the refrigerant flowing out of the evaporators A1, B1, and Cl. temperature. During operation, first read the temperature values of the temperature sensors S4, S5, and S6 of each pipeline, and compare the temperature values of the temperature sensors S4, S5, and S6 of each pipeline; it is judged whether the highest temperature value is higher than other temperatures The average value of the value, and then adjust the opening and closing time of the 200426327 solenoid valve 44, 45, 46. Please refer to the following steps for this refrigerant: 3 Yes a. Read the temperature of each pipe · The temperature values of S4, S5, and S6; b. Compare the temperature sensors of each pipe S4, S5 And other temperature values; e. Determine whether the highest temperature value is higher than the average value of other temperature values; f. When the highest temperature value is greater than the other temperature_average value, Qin Ying should open and close the time between the electromagnetic fields E4, E5, and E6; And repeat the above actions. The invention also includes a return air temperature sensor Sa, Sb, Sc for the return air temperature. When the duty-return air temperature view &,%, & side reaches the working temperature, the corresponding solenoid valves E4, E5, and E6 are opened for a fixed time. Referring to Figures 2 and 4, the control process of the present invention is applicable to a cold / warm cycle device. Therefore, a cold cycle device is taken as an example. As described below, firstly, all the evaporators A, b, and c are turned on. The temperature sensors Sa, Sb, Sc and the pipeline temperature sensors si, S2, S3 also work at the same time, and the detected temperature is returned to the controller 5 for comparison. When the return air temperature sensors Sa, Sb, When the temperature detected by Sc does not reach the set temperature, the controller 5 performs the following steps: a. Read the detection temperature of the three-pipe temperature sensors SI, S2, and S3; b. Compare the three pipes The temperature detected by the temperature sensors S1, S2, and S3; c. Determine whether the lowest temperature value is lower than the average value of other temperature values. For example, if the pipeline temperature sensor 13 200426327 is not the lowest, then step d will Correspond to the full opening of the solenoid valve E3, let the refrigerant get an IL into the evaporator C to reduce the temperature, and then repeat the same action from step a in this way. If the temperature of the pipeline temperature sensor S3 is the lowest, a step Y is performed to determine whether the official temperature sensor S3 is lower than the average value of the pipeline temperature sensor. If the pipeline temperature sensing $ S3 is lower than the pipeline temperature sensing 1 s: l, the average value of S2 ', then the corresponding solenoid valve E3 will be closed by step f, and return to step a to repeat the judgment and set the solenoid valve. The opening time of E3 is shown in Figure 5. Its control method is the temperature towel at a fixed time period, which is only turned on for 1 time, and the rest (㈣) time is the closing time. Remaining pipeline temperature !, when the average value of the four devices SI S2 ', the solenoid valve E3 is only opened for a short period of time, and a small amount of refrigerant flows into the evaporator c, the (Ml) daily pin is closed, and the experimental fee is reduced when the material center t T, Then 4 could not enter the G towel; when the temperature sense of the pipeline = temperature is closer to the average value of the pipeline temperature sensor s2, the electromagnetic force is equal to 7 = ^^ 卩 and then increases to T2; and # 此 而 财Controller temperature = Road: When the average value of the sensors S1 and S2 is 1, the electromagnetic door is opened when the time is 3, the time gate is ρ1M ^ time Te'TC ^ A value is τ, that is, the solenoid valve E3 is fixed for time Tc On, (T_Te) time off. According to the foregoing process, when the return air temperature sensor Sc of the greedy γ ^ transmitter C has reached a preset temperature, the valve will be recognized by the obstructing valve ~, & The meaning of Figure 1 is m. The other two evaporators A and B are compared in Figure 3 and the corresponding solenoid valves are closed in Figure 5 14 200426327. If the detection temperature of the return air temperature sensor Sb reaches the preset temperature at this time, At that time, the evaporator B switches the solenoid valve E2 with Tb for a fixed time; until only the single-peak II㈣ is left, the return air temperature is reduced and the temperature is directly set to the temperature than the car 乂. Stable 1E3 for opening and closing. " Refer to Fig.6 and Fig.7.

The refrigerated air is blown out / blown out by the air outlets of the devices A, B, and C. After the indoor circulation, the return air temperature is sensed by Sa, Sb. And Sc. However, when necessary, the present invention can add other temperature sensors at any position in the space where steaming Qi Zhai A, B, and G are installed, in order to seek more control points and facilitate the control of the temperature of the evaporators A, B, and C.
