Abstract: A wiring system for use in an air conditioning system comprising a printed circuit board having wiring receptacles and wiring connectors. In one aspect, at least some of the wiring receptacles comprise two or more wiring sub-receptacles, and each of the wiring sub-receptacles includes a slotted sub-receptacle connection pattern. Furthermore, the slotted sub-receptacle connection pattern of each of the wiring sub-receptacles is different from every other sub-receptacle connection pattern. Each of the wiring connectors includes a ridged connection pattern that is different from every other ridged connection pattern of the wiring connectors, such that a given wiring connector is receivable within only one of the wiring sub-receptacles. An air conditioning system and a method of manufacturing is also provided.

Abstract: A space conditioning system for controlling the temperature and humidity of air within an enclosed space includes a vapor compression refrigeration unit having a reheat coil disposed downstream of the system evaporator coil to reheat return air after cooling and condensation of excess water vapor in the return air by the evaporator coil. The system includes a damper for controlling inflow of ambient outdoor air, depending on the total enthalpy of the outdoor air, so as to satisfy cooling and the dehumidification requirements without operating the refrigeration unit when the enthalpy of the outdoor air is suitable. The system includes a programmable controller for controlling air temperature and humidity within the enclosed space by sensing outdoor air enthalpy, temperature and humidity of air within the enclosed space and temperature or enthalpy of supply air being admitted to the enclosed space.

Abstract: Heat pump apparatus for heating liquid, such as water, includes a refrigerant circuit and a water circuit, a refrigerant-to-water heat exchanger and an air-to-refrigerant heat exchanger operably disposed in heat exchange relationship with a air fluid stream of a systemically separate primary source of space conditioning. A compressor is provided for circulating the refrigerant between the two heat exchangers and a water pump is provided for circulating the water to be heated through the refrigerant-to-water heat exchanger. A tank is also provided for storing the heated water. The tank has an electrically resistive heating element operably associated therewith. A control circuit is provided for normally enabling operation of the heat pump and disabling the heating element in response to a demand for liquid heating.

Abstract: A variable air volume system for processing an enclosure is shown and described. The system includes an improved damper assembly, having independently operated damper elements, and an air mover control responsive to the damper assembly.
