Benefits of technology

"The invention is a Thermal Separator / Power Generator (TSPG) that can be used as a standalone machine or in a distributed network of machines. It is designed to efficiently produce heat, cooling, and power for various applications using natural refrigerants. The TSPG has a high thermal output suitable for heating applications and a low thermal output suitable for cooling applications. It can also be used in conjunction with other waste heat sources for efficient energy management. The invention provides a single platform with the flexibility to meet different needs and can be powered by natural refrigerants, biofuels, or fossil fuels. The unique properties of natural refrigerants are taken into consideration for practical use. The patent text also describes the use of carbon dioxide and ammonia as potential refrigerants for the TSPG."

Problems solved by technology

Although natural refrigerant hydrocarbons are cited and studied, it is noteworthy that little work has been accomplished in the art in consideration of ammonia and carbon dioxide natural refrigerants combined in new ways for CCHP systems.

Embodiment Construction

[0055]Turning to FIGS. 3 and 4, there is illustrated a schematic diagram of applicant's invention. There is a Thermal Separator Module (“TSM”) 10 that thermally separates and amplifies low grade or low quality heat sources that are generally less than 100° F., into individual, dual hot and cold thermal streams. This is conventionally known and practiced in current heat pump technology.

[0056]There is a drive motor 38 and compressor 40 to power a CO2 vapor compression cycle in the TSM 10 by any of a number of power sources indicated at 12. These can be various forms of hydraulic power such as hydraulic power packs, wind hydraulics, farm implements, or other hydraulic means. The drive motor can also be conventionally powered by means of electrical energy.

[0057]As can be seen in FIG. 3, the TSM has both a hot loop 14 and a cold loop 16. The hot loop 14 has various applications 18 that it can satisfy a temperature boost up to ˜250° F. for the RPG working fluid in a thermal exchange betwe...

Abstract

A thermal separator / power generator uses the thermodynamic properties of refrigerant substances to provide supplemental heating, cooling, and power without emitting any additional greenhouse gases to the environment by utilizing waste or unused heat energy. This is accomplished through the combined operation of a Rankine Cycle Generator using a refrigerant, preferably a natural refrigerant such as NH3, as the working fluid, and a CO2 a vapor compression heat pump cycle, also called a Thermal Separator Module. The combined system is called a Thermal Separator / Power Generator. It produces electrical power and simultaneously produces secondary heating and water or air cooling as byproducts. In the combined vapor compression heat pump / Rankine power generator cycle, waste heat from external source(s) are recovered and used for heating in the Rankine power cycle. The CO2 heat pump provides cooling and optional space or process heating in lieu of heat boost efficiency for the Rankine power generator cycle.

Description

I. CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is based on and claims priority of U.S. provisional patent application 61 / 284,936 filed Dec. 28, 2009.II. FIELD OF THE INVENTION[0002]This invention relates to a more efficient and flexible method of providing Combined Cooling, Heating, and Power (CCHP); so-called Tri-generation. The invention embodies a mechanical / electrical power generation system that also produces selectable heating and cooling outputs in an environmentally clean and energy efficient way. A combined thermal separator / power generator uses the thermodynamic properties of natural working fluids to provide supplemental heating, cooling, and power without emitting any additional greenhouse gasses to the environment by use of waste or unused heat energy. This is accomplished through the combined operation of a Rankine cycle, using a refrigerant such as ammonia (NH3) as the working fluid for power production; and a carbon dioxide (CO2) heat pumping cycle....
