A heat pump can provide warm air to a house even when the temperature outside is below freezing. I have said before and I’ll say it again: refrigeration is the single greatest invention ever invented by man. At least Thomas Edison never tried to claim the credit that he invented that. As far as I […]

End clamp housing for attachment to a cylindrical body, the side end housing being a unitary metal casting comprising; an open annular base element provided with a first, ingoing flange at a first side of the base element and a second ingoing flange at a second side of the base element. The second ingoing flange […]

Boosted source heat pump (BSHP) is presented having a primary compressor, a booster compressor, an economizer, and a lubricant management system. At least the primary compressor is a twin-single compressor. The lubricant management system includes traps to prevent migration of lubricant to a non-operating compressor, and aspiration tubes from the sump to the low pressure […]

Microprocessor based control system monitors and controls a heat pump water heater system and interfaces the water heating system with an external centralized control system. The microprocessor control system includes sensors, safety switches, device interface relays, user interface devices and precanned software to provide versatile monitoring and control over a heat pump type water heating […]

Improved hydrogen-hydride absorption systems for improving the energy utilization in refrigeration and heat pump cycles comprise reactor systems for chemically forming three or more hydride components, means for supplying heat to and removing heat from the hydride in the respective systems, and means for conveying hydrogen between the several reactor systems. A method for deriving […]
