Embodiment Construction
[0026] The method of the present invention is based on the relationship between the compressor exhaust temperature Tp of the multi-connected central air conditioner, the outlet temperature T3 of the outdoor unit heat exchanger, and the temperature T2 of the indoor unit heat exchanger, and with certain rules, the electronic expansion valve of the control system is opened. In order to implement a control method for adjusting the refrigerant flow rate of the system.
[0027] Such as figure 1 As shown, taking an inverter air conditioner as an example, the refrigeration system of the inverter air conditioner of the present invention includes a compressor 10 , a four-way valve 8 , an outdoor unit heat exchanger 1 , an electronic expansion valve 3 , and an indoor unit heat exchanger 6 . The electronic expansion valve 3 is a throttling part of the refrigeration system. A first two-way stop valve 4 is provided between the electronic expansion valve 3 and the indoor unit heat exchanger ...
