Title: Hot gas engine
Inventor: SEKIYA HIROSHI
IPC: F25B9/14
Filed: 1991-12-09
Abstract: PURPOSE:To obtain a hot gas engine in which room cooling/heating capacity and a thermal efficiency are improved. CONSTITUTION:A gas moving volume of an intermediate temperature chamber 5 in a hot gas engine is set larger than that of a high temperature chamber 4 thereby to increase a decreasing degree of a pressure of operation gas in a heat absorbing stroke, thereby improving room cooling capacity. On the other hand, a rising degree of a pressure of operation gas in a heat radiating stroke is increased to improve room heating capacity and since a heat absorption amount of a high temperature side heat exchanger 10 is substantially constant irrespective of an increase in the gas moving volume in the chamber 5, its thermal efficiency is improved.
