Title: Ejector cycle, gas and liquid separator employed for the same and hot-water supplier, and heat control system employing the ejector cycle
Inventor: TAKEUCHI HIROTSUGU
IPC: F25B41/04
Filed: 2001-03-15
Abstract: PROBLEM TO BE SOLVED: To improve the performance coefficient of a refrigerating cycle, while realiz ing dechlorofluorocarbonizing countermeasure. SOLUTION: Carbon dioxide is employed as refrigerant in an ejector cycle, while reducing the pressure of the same to expand in an ejector 400 from the super critical zone of the same. According to this method, the difference in the specific enthalpies (adiabatic heat drop) between the refrigerant inlet port of a nozzle 410 and the refrigerant outlet port of the nozzle 410 can be increased, since ratio of changing amount Δh of the specific enthalpy with respect to the amount of change Δp of pressure (Δh/Δp) of carbon dioxide is larger, as compared with that of chlorofluorocarbon and, in addition, a pressure difference upon pressure reducing and expansion is increased.  The gas phase refrigerant and the liquid phase refrigerant have substantially the same density in the supercritical zone, whereby the liquid phase refrigerant and the gas phase refrigerant, reduced in pressure and expanded in the ejector 400 (nozzle 410), are accelerated substantially to the same speed. Accordingly, energy conversion efficiency in the ejector 400 (nozzle 410) is increased, whereby the performance coefficient is improved.
