Abstract
Abstract Apparatus for comfort conditioning at least a zone of a building is disclosed. The apparatus comprises, as its main elements, a solar collector, a heated fluid storage tank, an internal combustion engine, a sensor-controller responsive to the temperature of fluid in the heated fluid storage tank, air conditioning apparatus and a sequencing switch. The apparatus also includes means including at least one pump for circulating a heat transfer fluid from the heated fluid storage tank, into heat-receiving relationship with the solar collector, into heat-receiving relationship with the engine, and back to the tank. The sensor-controller is operable to cause the internal combustion engine to operate whenever the fluid temperature in the heated fluid storage tank is below a control point and to control the engine, when operating, to maintain the temperature of fluid within the tank within predetermined limits. The air conditioning apparatus includes a chiller of the compressor-condenser-evaporator type, a dehumidifier which employs a desiccant, means including at least one pump for transferring heat from the heated fluid storage tank into regenerating relationship with the desiccant of the dehumidifier, a sensible cooling coil, means for transferring heat from the cooling coil to the evaporator of the air conditioning apparatus, and means including at least one blower for circulating air in dehumidifying relationship with the dehumidifier, in heat transfer relationship with the sensible coil, and to the space to be conditioned.
