Abstract

The invention provides an electric swelling valve which can have some leakage at the fully closed position so when the flow is controlled under small volume, the controller will not be fully closed. The cooling cycle has the electric swelling valve which can be fully closed so the air conditioner can control the extent of openness at the specified time interval. The feature is that when the openness of valve is under the specified openness, the control can limit the deviation under the specified range. So, when the valve is toward closed status, the deviation of openness of valve can be still under control.
