Abstract: A cooling system that has an electrical controller that controls an electric expansion valve and the defrost cycle using a reversing valve. The need for heater circuit to achieve defrost is eliminated. The system permits the defrosting the evaporator system in less time required for conventional defrost methods. The cooling system also eliminates the need for a head pressure control valve and check valves. Due to the less wiring and lower operating costs, the invention provides significant cost savings.
Abstract translation: 一个冷却系统，带有一个电子控制器，可通过换向阀控制电动膨胀阀和除霜循环。 消除了加热器电路实现除霜的需要。 该系统允许在传统除霜方法所需的更少时间内对蒸发器系统进行除霜。 冷却系统也不需要头压力控制阀和止回阀。 由于较少的布线和较低的操作成本，本发明提供了显着的成本节约。
