Combined with the issue of liquid hammer of 4-Way Reversing Valve for airconditioner,the fluid flowing through the 4-Way Reversing Valve is analyzed and tested.It is found that liquid refrigerant flows through the 4-Way Reversing Valve while the air-conditioner starts for period of time,after the air-conditioner is out of running for a while.Based on the mechanism of liquid hammer of the 4-Way Reversing Valve in air-conditioning system,when the air-conditioner starts as heating mode,in order to avoid the liquid hammer damage of 4-Way Reversing Valve cased by the liquid refrigerant flowing through the 4-Way Reversing Valve ,it is proposed that the interval of starting time of the compressor and the 4-Way Reversing Valve should be set reasonably based on the lasting time of liquid refrigerant from the discharge outlet since the air-conditioner compressor starts to operation.
