摘要： A method and apparatus utilizing a hot gas defrost system wherein superheated gas from the system compressor is conducted into a heat exchanger mounted within an accumulator for supplying heat to vaporize liquid refrigerant received from the evaporator. After the gas passes through the heat exchanger it is conducted to the condenser where it is condensed to a liquid and then routed to the evaporator. In the evaporator or frost accumulating coil the liquid refrigerant is subcooled, supplying heat to melt the ice formed on the evaporator surfaces and the liquid is thereafter conducted to the accumulator where the heat supplied from the heat exchanger acts to vaporize the fluid. The vaporized refrigerant is then recycled to the compressor to complete the system.

摘要： A heat exchange unit is disclosed which is capable of being mounted either in a vertical or horizontal position. A condensate pan including multiple drain openings each serving a particular position is additionally disclosed. A cover plate secures the condensate pan by providing a drain projection opening into which a projection from the condensate pan may extend. A drip pan for coacting with the condensate pan is provided when the unit is mounted in the horizontal position.
摘要翻译：公开了能够安装在垂直或水平位置的热交换单元。另外公开了一种包括各自用于特定位置的多个排水口的冷凝盘。盖板通过提供排水突出开口来固定冷凝盘，冷凝盘的突出部可以延伸出来。当单元安装在水平位置时，提供与冷凝盘共同作用的滴水盘。
