摘要：
The present invention relates to a self-contained air conditioning unit including a reversible refrigeration system and more particularly to a control system having a plurality of sensing means that are effective in maintaining operation of the unit in a heat mode by use of a supplemental heater when the ambient and the surface temperature of selected refrigeration components are above a preselected frosting temperature, and a secondary heater when the system is in a defrost mode.
