Filed:
Jan 22, 2010
Appl. No.:
12/691851
Inventors:
Randall O. Edwards - Chelsea VT, US
International Classification:
F25B 19/00, F24C 3/00
US Classification:
62 7, 62267, 62304, 126 85 R
Abstract:
Embodiments of the disclosed technology comprise a combination refrigeration and combustion system including a tank that holds liquefied gas, an expansion valve in fluid connection with the tank, and a sealable chamber housing an evaporator, with the evaporator in fluid connection with the expansion valve. The system is configured for expulsion of the liquefied gas from the tank into the expansion valve. The expulsion takes place in at least one pulse over part of a defined time interval. After an expulsion of gas, the liquefied gas expands into gaseous form in the evaporator, allowing for continuous combustion of the gas in gaseous form.
