Embodiment 1
[0021] Such as figure 2 As shown, this embodiment provides an adaptive throttle valve 3, which includes a first chamber 31 and a second chamber 32. The first chamber 31 is accommodated in the second chamber 32. The first chamber 31 communicates with the second chamber 32 through a plurality of orifices 35 provided on its side wall, and the second chamber 32 communicates with the valve outlet; the first chamber 31 is With a constant cross-sectional structure, the first chamber 31 is provided with a piston plate 33 that is sealed to the inner wall of the first chamber 31, and the piston plate 33 divides the first chamber 31 into a first sub-chamber 311 and the second sub-chamber 312, the first sub-chamber 311 is in communication with the valve inlet, and the piston plate 33 can move along the length of the first chamber 31 to adjust the communication between the first sub-chamber 311 and the The number of orifices 35 in the second chamber 32.

Embodiment 2
[0029] In the refrigeration state, when the indoor load of the air conditioning system changes, the pressure of the refrigerant on the high-pressure side flowing out of the condenser 2 will change. The higher the load, the greater the pressure of the refrigerant on the high-pressure side; based on this principle, as figure 1 As shown, this embodiment also provides an air conditioning system with the adaptive throttle valve 3 as described in the first embodiment. When the valve inlet, that is, the refrigerant pressure on the high-pressure side of the air conditioning system increases, the communication area between the first sub-chamber 311 and the second chamber 32 will increase accordingly, and the amount of refrigerant passing through the adaptive throttle valve 3 per unit time Increase it to bring more cold capacity to the evaporator 4 to ensure the cooling effect. That is, by using the adaptive throttle valve 3, the air-conditioning system can realize the purpose of automati...
