Electromagnetic coil is made up of coil component and magnet case, by bolt combination part 18 electromagnetic coil is fixed on the pilot valve.
When air-conditioning needs refrigerating operaton, the electromagnetic coil outage, under the effect of returning spring, core iron trailing frame assembly drives sliding bowl and is moved to the left together, thereby make e, c two capillary tubies and c, d two capillary tubies communicate respectively, because taking over, S is low pressure area, so the gas in chamber, a main valve left side passes through e, s capillary tube and sliding wrist inner chamber and flow into low pressure area, therefore chamber, a main valve left side becomes low pressure area, and the pressurized gas of compressor air-discharging end pass through d, the c hair is taken over and is entered the right chamber of main valve, thereby the right chamber of main valve becomes the zone of high pressure, just formed a pressure difference between the chamber, the left and right sides of main valve, under this action of pressure, slide block and piston are shifted to the left side, make E, S takes over and communicates D, C takes over and communicates, this moment, the refrigeration working medium circulation path of internal system was: pressurized gas → D adapter → valve body → C adapter → outdoor heat converter → throttle element → indoor heat converter → E adapter → slide block → S that compressor is discharged take over → is sucked by compressor then, and system realizes refrigeration cycle.
When air-conditioning needs heating operation, the electromagnetic coil energising, under the effect of coil electromagnetic force, core iron trailing frame assembly overcomes the active force of returning spring and drives sliding bowl and move right together, and c, s two capillary tubies and e, d two capillary tubies are communicated respectively.The gas in the right chamber of main valve passes through c, s capillary tube and sliding bowl inner chamber and flow into low pressure area, make the right chamber of main valve become low pressure area, and the pressurized gas of compressor air-discharging end pass through d, the e hair is taken over and is entered chamber, a main valve left side, thereby make chamber, a main valve left side become the zone of high pressure, just formed a pressure difference between the chamber, the left and right sides of main valve, under this action of pressure, the piston of slide block is shifted to the right side, make C, S takes over and communicates, D, E takes over and communicates, the refrigeration working medium circulation path of this moment is: exhaust outlet of compressor → D adapter → valve body → E adapter → indoor heat converter → throttle element → outdoor heat converter → C adapter → slide block → S adapter → compressor air suction mouth, system realizes heating circulation.
As mentioned above, just can realize the commutation of main valve by the acting in conjunction of electromagnetic coil and pilot valve, and switch the circulating direction of refrigeration working medium by the commutation of main valve, make indoor heat converter become the condenser of the state that heats from the vaporizer of refrigerating state, outdoor heat converter has then become the vaporizer of the state that heats from the condenser of refrigerating state, thus the purpose of the dual-use that makes heat pump type air conditioner realize freezing summer to heat winter.
The heat pump air conditioner electromagnetism four-way change-over valve of said structure, the spacing hole of the trailing frame in its pilot valve only has very little fit up gap with sliding bowl at length direction, just for the ease of the assembling of trailing frame and sliding bowl, this fit up gap is generally below 0.1mm in its effect.When sliding bowl moves with trailing frame, trailing frame does not have impact force to promote the motion (its structure is seen figure three) of sliding bowl, energising starts and cuts off the power supply all needs bigger electromagnetic force when replying, thereby the electromagnetism four-way change-over valve adopts the constant voltage step mode, the starting resistor and the sustaining voltage of electromagnetic coil are voltage rating, electromagnetic coil will generate heat in constant galvanization, thereby makes the safety reliability of electromagnetic coil reduce.
