The present disclosure is directed to in grade light fixtures and recessed luminaires and subassemblies thereof, including, for example, a heat sink and pivot for a recessed luminaire, a gasket for the recessed luminaire, and an outer box and cover for installation of the recessed luminaire. The recessed luminaire comprises: a housing having an internal surface; and a light subassembly engaged with a thermally conductive body, the light subassembly having a first end and a second end, wherein the first end of the light subassembly is pivotally secured to a pivot arranged on, in, or proximate to the internal surface of the housing. The thermally conductive body is in thermal contact with the internal surface of the housing. The recessed luminaire further comprises a dehumidifier.

Power generating plants discharge steam or hot water typically from a steam turbine to a condenser system for the purpose of cooling the discharged fluid prior to its being recirculated. The condenser system receives water from an ambient source pumped using a circulating water pump, said water being elevated to a temperature on the order of 115.degree. F. to 125.degree. F. upon passing through the condenser system. The condenser system can operate in basically two different states to provide either single pressure, single pass condenser operation when the waste hot water is discharged to the source and not used, or multi-pressure, multi-pass condenser operation to maintain an elevated hot water supply that is fed to a load (utilization equipment). Valve controls are provided for enabling serial-to-parallel and vice versa, switching between modes of operation without difficulties and with only a slight drop in load during the transition. The heated water is temperature controlled to the above mentioned range. The system is particularly adaptable to use with a plurality of power plants by combining the discharges of several plants as needed, or by removing plants from the waste heat system when not needed. A special pressure control is provided at all plants to compensate for variations in water flow occasioned by changes in electric generation.

A system for utilization of waste heat streams, such as from a power plant, for the heating of buildings or for other uses of heat streams under 200.degree. F. employing preferably a multi-stage heat pump selectively operable to raise the temperature of the building heating system (heated fluid) above the temperature of the waste heat stream (heating fluid). The multi-stage heat pump comprises separate stages each including an evaporator, condenser and compressor, and a heat exchanger. The heat pump may be connected either as a counter flow heat pump or a parallel flow heat pump. The control of the system is in at least two different modes dependent upon the demand (load). In the low load mode heat transfer to the building heating system occurs without operation of the heat pump. In this mode heat transfer occurs with the heat exchanger operating in combination with passive evaporator-condensor action with the compressor of the heat pump being by-passed to maintain the heated fluid outlet temperature at a preset value by controlling mass flow of the heating fluid as a function of sensed heated fluid outlet temperature. Once the load increases past a predetermined point the heat pump is activated and maintains the heating fluid outlet temperature constant. At short peak loads the total mass flow into the heat pump is limited thus relying upon the heat pump to extract more heat from the heating fluid to meet the peak loads. The control of the heating fluid stream is preferably accomplished with a single valve controlled as a function of the three variables; (1.) heated fluid outlet temperatures; (2.) heating fluid outlet temperature; and (3.) mass flow.
