Embodiment
First embodiment of the second H type automobile air conditioner heat expansion valve of band filtration of the present invention is as shown in Figure 1:
The compressed machine 41 of gaseous refrigerant is collapsed into the high pressure-temperature gaseous refrigerant, become high pressure liquid refrigerant through condenser 42 condensations, high pressure liquid refrigerant drying cistern 43 enters the second H type automobile air conditioner heat expansion valve 44 of band filtration from the attachment hole 9 of the second H type automobile air conditioner heat expansion valve 44 of band filtration, through valve port throttling prepass 4,5 enter and experience temperature by bellows and regulate the valve port throttling passage 6 of channel cross-section automatically and carry out the throttling first time, high pressure liquid refrigerant becomes the low-pressure low-temperature gas-liquid mixed refrigerant after the throttling first time, passage 7 enters throttle orifice 8 and carries out the throttling second time after the valve port throttling, the low-pressure low-temperature gas-liquid mixed refrigerant becomes pressure and temperature after the throttling second time lower, the gas-liquid mixed refrigerant that the gaseous refrigerant ratio is higher, entering vaporizer 45 heat absorption evaporations through attachment hole 10 becomes low-pressure gaseous refrigerant, gets back to compressor 41 through the second H type automobile air conditioner heat expansion valve 44 top air cavitys of band filtration and finishes refrigeration cycle.
Because high pressure liquid refrigerant is through second throttle, can effectively solve ubiquitous fluctuation of heating power expansion valve and vibration, filter screen 2 can be blocked in impurity remaining in the refrigeration system outside the thermal expansion innervalve assembly, can improve the Energy Efficiency Ratio and the refrigerating capacity of refrigeration system, and guarantee the proper functioning of refrigeration system.
