Study on a non-powered heat transporting system; Mudoryoku netsu hanso system ni kansuru kenkyu

Abstract

This paper proposes a non-powered heat transportation (HT) system. The system is composed of an evaporator, condenser, receiver, switching chamber (SC) and 3 check valves which are connected with each other by vapor and liquid tubes. Condensed liquid supercooled in the condenser exists in the receiver forming a saturated condition at a concerned temperature, and condensed liquid is lifted up from the condenser to the receiver by pressure difference between the evaporator and receiver. Generally evaporation pressure is higher by pressure difference between liquid levels in the condenser and receiver. The lifted up amount of condensed liquid increases with evaporation pressure, resulting in an increase in heating surface area of the condenser and amount of condensed liquid. A proper evaporator pressure is thus retained by reduction of evaporation pressure. SC is connected with the receiver and evaporator, and switches high- and low-pressure valves by motion of an inner float to transport heat from the evaporator to condenser. Reverse HT is possible as normal latent HT by installing a bypass. Some problems are also described. 2 refs., 8 figs.
