Study on Double Channel Shunt Perfusion Technology
At present,the refrigerant perfusion methods of air conditioning are small valve perfusion and process pipe perfusion.The small valve perfusion has high quality reliability,low material cost and easy automation,but the perfusion efficiency is low.The use of process tube perfusion quality reliability,high perfusion efficiency,but increase the cost of materials,difficult to achieve automation;Therefore,a double-channel shitter perfusion method is proposed,which is suitable for automatic perfusion station.Double pipes are used to connect large and small valves,and the refrigerant flow is controlled through the electromagnetic valve switch.When the refrigerant flows to the large valve,the four-way valve is in a heating state,and cold coal enters the exhaust side of the compressor.Little effect on starting torque;After the set filling time of the large valve is completed,switch the small valve to complete the remaining filling amount.
