Abstract: A microturbine system includes a compressor, a recuperator assembly, a combustor, a turbine, and a generator. The recuperator assembly includes a core that preheats compressed air provided by the compressor with exhaust gas from the turbine.

The recuperator core is surrounded by a recuperator housing that is intimate with the recuperator core such that the recuperator housing assumes substantially the same temperature as the recuperator core. The recuperator housing is constructed of materials that have a coefficient of thermal expansion that is substantially equal to that of the recuperator core, and that have thicknesses substantially equal to the thickness of the recuperator core materials. A superstructure supports the recuperator core and resists expansion of the core in a stackwise direction.

Abstract: In a heat-pump water heater with a super-critical refrigerant cycle, a valve open degree of a decompression valve is controlled to control a pressure of high-pressure side refrigerant so that a temperature difference between refrigerant flowing out from the water-refrigerant heat exchanger and water flowing into a water-refrigerant heat exchanger is set in a predetermined temperature range. Thus, the pressure of high-pressure side refrigerant in the super-critical refrigerant cycle can be controlled, thereby suitably adjusting heat-exchange performance of an internal heat exchanger, and restricting the temperature of refrigerant discharged from the refrigerant compressor from being uselessly increased.

Abstract: The air conditioning system can draw power from the utility power grid via an electrical line or from a battery. When the air conditioner is used during off peak hours, the air conditioner will draw power directly from the power grid. During peak usage, the air conditioner will be provided with power from the battery. The battery, in turn, is recharged from the power grid during off peak hours, such as during the night. In this way, the battery is kept fully charged and able to provide power during the peak period. The flow of the power to the air conditioner from the battery or line power is controlled by a timer switch. The flow of line power to the air conditioner or battery recharger during off peak hours is controlled by a recharge timer switch. The result is an air conditioning system reducing the strain on the power grid during peak usage and having an alternative power source, the battery, charged during off peak hours.
