Title: Compressor of the freezer and engine
Inventor: KIM WON BONG
IPC: F25B1/00
Filed: 2001-06-16
Abstract: PURPOSE: A heat engine refrigerating compressor is provided to achieve improved heat efficiency and simplify configuration of heat engine refrigerating compressor, while reducing contamination of exhaust gas. CONSTITUTION: A compressed air is generated by the reciprocation of a compressor, and the compressed air is partially cooled to a low temperature compressed air in a water-cooled heat exchanger. The low temperature compressed air is expanded while passing through an expansion valve(600) through a dehumidifier. The residual compressed air reacts with the fuel in a burner, thus generating a high temperature high pressure compressed combustion gas. An expander(300) reciprocates by the compressed combustion gas so as to generate hydraulic pressure. The exhaust gas from the expander is heat exchanged by the water-cooled heat exchanger, and exhausted in a low temperature gas, thus generating condensed water. The condensed water circulates to a cooling water tank(7) through a gas-liquid separator(10). A high pressure vapor is generated by the compressed heat produced during the heat-insulated compression of the air in the heat exchanger and the heat of the exhaust gas. The high pressure vapor is injected into the outlet of the burner and mixed with the compressed combustion gas so as to generate an overheat vapor. The hydraulic pressure generated by the expander works as a working hydraulic pressure source for the compressor.
