Strathman, R L

The system includes a container and a door therefor, each comprised of inner and outer shells made of a moisture impervious material having sealed therebetween an insulating material. A holding plate, containing a eutectic solution and a refrigerant evaporator coil, is disposed within the container. A refrigerating circuit is provided including a compressor and condenser coil connected to the evaporator coil. A control unit monitors the eutectic solution temperature and the refrigerant temperature at the compressor output. It minimizes the operating times of the compressor and condenser fan necessary to maintain preferred temperatures inside the container in order to minimize the drain on batteries which are provided for powering the same. In addition, an array of solar cells is provided and the control is adapted for powering the compressor and condenser fan with their output when it is above the predetermined minimum operating level.
