Among them, the compressor 2, the condenser 22, the expansion dam 26, and the compressor controller are common devices in the conventional refrigerating and air-conditioning apparatus. In the first embodiment, the pressure detecting device 20A is disposed between the pressing unit 21 and the evaporator 22 to detect the pressure between the compressor 21 and the evaporator a. First, the frequency control device 2 OJB will be The user requests the capacity to determine the remaining or non-amplitude of the operating rate of the compressor U to determine the value of the j-shrinking machine 21 and the evaporator 22 $ (this part of the control method 4 Mai Zhao said In addition, since a feedback mechanism is set between the frequency control device 2〇B and the pressure detecting device 20A, the Qingli detecting device 2〇a will continuously detect the pressure between the compressor 21 and the evaporator 22 to the guessing The obtained pressure deviates from the determined pressure level value, and the frequency of the power supply of the compressor 21 is controlled by the frequency of the power source of the whole wheel, so that the pressure between the compressor and the evaporator 22 is determined. Although the frequency control device 20B adjusts the frequency f' of the power source input to the compressor according to the pressure level value, the temperature generated by the evaporator 22 can satisfy the demand of the user, and the condition T can still be relied upon. The speed should be turned to low speed as much as possible to save energy. There is only one evaporator 22 in this first embodiment. Usually replenished in the store _ put cold _, can be used - a refrigerator using a compressor, or a plurality of refrigerators - a compressor, using the above method, regardless of the combination of the refrigerator is - For one, one-to-one = right, you can easily reduce the compressor speed, but refrigerate and remove: hold the required low temperature. The α will be further step-by-step description—the condition of a compressor corresponding to several refrigerators.
