Abstract
Abstract A heater/cooler unit specially adapted for motels, hotels, hospitals and like structures enables adjacent rooms to be cooled or heated by using certain commonly shared components. An evaporator is disposed in each of two adjacent rooms. The evaporators are connected to a common compressor and condenser disposed outside the rooms. Appropriate control mechanisms are provided to enable the evaporators to operate independently. The components are disposed in a housing which forms a portion of the exterior wall of the structure and a portion of the common wall of the rooms. Certain of the components can be placed atop a cart which can be wheeled into and out of the housing so as to facilitate installation and servicing of the unit. Electrical strip heaters can be added to the evaporators to provide a heating capability. An alternative embodiment employs interior and exterior heat exchangers operated as heat pumps.
