PURPOSE:To constantly obtain a desired quantity of heat being transported by detecting the temperature or the internal pressure of a condenser or a tank connected thereto or the both, and increasing or decreasing the input to a heater of an air bubble pump in accordance with the signal thereof. CONSTITUTION:When power is supplied to a heater on the root portion of a rise-up pipe 9, which is located near to a condenser 1, an evaporative liquid 12 existing in the condenser 1 receives heat and boils up. Air bubbles being generated draw up together the liquid 12 existing in the periphery thereof, and run over the top portion of the rise-up pipe 9, descending within a liquid return pipe 8 and reaching an evaporator 4. The liquid 12 receives heat from the outside of the evaporator 4 and evaporates. Vapor being generated reaches the condenser 1 via a vapor rise-up pipe 7 due to a vapor pressure difference. The vapor is cooled in the condenser 1 and discharges condensation heat and drops in the form of a liquid. After falling within a pipe 2 of the condenser 1, the liquid flows into the rise-up pipe 9 and the same cycle of the operations is repeated. A sensor 14 is hermetically attached to a part of the condenser 1, and signals P and T from the sensor 14 are delivered to a control part 13 to vary the quantity of input amount W of the heater 10. |
