A heat engine (10) achieves operational efficiencies by: 1) recovering waste heat from heat engine expander (14) to preheat heat-engine working fluid, 2) using super-heated working fluid from compressor (402) to pre-heat heat-engine working fluid, and 3) using reject heat from condenser (93) and absorber (95) to heat the heat-engine boiler (12). A dual heat-exchange generator (72) affords continuous operation by using gas-fired heat exchanger (212) to heat generator (72) when intermittent heat source (40), e.g., solar, is incapable of heating generator (72). The combination of heat engine (10) and absorption and compression heat transfer devices (60, 410) allows use of low-temperature heat sources such as solar, bio-mass, and waste heat to provide refrigeration, heating, work output including pumping and heating of subterranean water and electrical generation.

This invention is for a highly efficient heat transfer unit and method for heat transfer for an air conditioning refrigeration unit. The invention has a plurality of condenser coils that stand generally vertically upright (with up to 20° tilt to optimize downward water flow with air being pulled across) between a splash louver and an evaporative fill material. The evaporative fill material and the splash louver transfer heat from the water by air cross flow to make the air conditioning unit very efficient and reduces the amount of copper coils needed. The condenser coils are cooled by water flowing down through them and into a sump. The condenser coils are also cooled by air pulled across them by a fan mounted on the top of the air conditioning unit. The sump in the bottom of the unit has a wall that directs the water in it to a water pump that then sends the water to the water distribution pipe. The water pipe covers the water distribution member with water, which then allows the water to flow down the condenser coils. The large amount of heat that is transferred from the condenser coils to the water and the air cross flow is what enables the air conditioning unit to be so efficient. A low pressure drop of refrigerant in the condensing coils, the large surface area, and horizontal air flow also helps the air conditioning unit to be efficient.

A continuous process and apparatus is provided for treating an impure liquid to produce purified liquid. The process includes electrically activating a thermoelectric module (24) to provide a first module heated surface (26) and a module cooler surface (28); feeding the impure liquid to the first module heated surface (26) to produce vapor of the liquid; and transferring the vapor to the module cooler surface (28), to effect heat transfer to the module cooler surface (28). The process further includes (a) directing a first portion of the vapor adjacent to or onto the module cooler surface (28) to effect heat transfer to the module cooler surface to produce a first condensed liquid; (b) directing a second portion of the vapor to condenser means (18) having a second cooler surface (46) remote from the module cooler surface (28) to effect heat transfer to the second cooler surface (46) to produce a second condensed liquid; and (c) collecting the first and second condensed liquids.

An improved cooling system for cooling the surfaces of electrical and electronic components with low additional power consumption and high heat transfer rates. The components to be cooled are in thermal contact with the cooling table evaporator unit. Refrigerant is circulated to the cooling stage evaporator unit by a liquid refrigerant pump, and the liquid refrigerant is at least partially evaporated by the heat generated by the element. The vapor is condensed through a conventional condenser coil, and the condensed liquid, along with any liquid that has not evaporated, is returned to the pump. The system works approximately isothermally in evaporation and condensation.
