摘要： PURPOSE:To attain energy-saving by using a plurality of heat storage tanks as heat storage tanks for cold heat sources in a cooling operation and by using a part of the heat storage tanks as a heat storage tank for hot heat in a cooling-heating operation. CONSTITUTION:In a cooling operation, both of heat storage tanks 1a and 1b serve as heat storage tanks for cold heat sources and both of heat exchangers 2a and 2b operate as evaporators inside, while a heat exchanger 3 provided separately from the heat storage tanks 1a and 1b operates as a condenser. Thereby cooling of each room is executed. In a cooling-heating operation, the heat storage tanks 1a and 1b in a plurality are divided into the heat storage tank for the cold heat source and a heat storage tank for a hot heat source and the heat exchanger 2a of the heat storage tank 1a for the cold heat source operates as the evaporator, while the heat exchanger 2b of the heat storage tank 1b for the hot heat source operates as the condenser. Thereby cooling and heating of each room are executed. According to this constitution, energy- saving can be attained and also the energy can be used effectively.

摘要： PURPOSE:To prevent a vapor tube from being plugged with liquid even when the tube is disposed at a lower level at a vapor outlet provided at an upper header tube than a gas/liquid separating mechanism and an upper header tube by providing the outlet communicating with the inner upper position from an exterior at the header tube. CONSTITUTION:Each evaporator unit 1 has several pipes 11 made of metal with satisfactory thermal conductivity, and an upper header tube 12 and a lower header tube 13 are respectively connected to the upper and lower ends of the pipes 11. The end of the tube 12 communicates with a terminal heat exchanger 5 disposed at a higher level than the liquid surface of operation liquid (c) via a vapor tube 2 and the tube 13 through a liquid tube 3. If the periphery of the unit 1 becomes a predetermined temperature or higher, the inner liquid (c) is boiled to derive the heat of the periphery thereby to cool the part. Even if it is vigorously boiled in the pipes 11, the liquid (c) to be scattered by the boiling does not arrive at a vapor outlet 17, and hence the tube 2 is not liquid-plugged.

摘要： PURPOSE:To impart high heat transfer coefficient even under low heat flux by composing of an outer tube and a shorter inner tube than the outer tube, and providing a narrow flowing gap communicating one end of the inner tube with the other end between both the tubes. CONSTITUTION:An inner tube 2 made of copper is inserted tito an outer tube 1 made of copper, disposed substantially at the center in the longitudinal direction of the tube 1, the lower ends of the tube 2 is allowed to protrude at four positions at an approximately equal angle interval until they are brought into contact with the inner peripheral wall of the tube 1 to form a protrusion 3, a narrow flowing gap 11 of 0.4mm of average is, for example, provided between the tubes 1 and 2 as an evaporator pipe. Bubbles (c) generated in the gap 11 by boiling generated continuously in the gap 11 are not accumulated at one position, and the part of liquid state not simultaneously boiled is not accumulated at one position. Accordingly, heat transfer is accelerated to improve heat transfer coefficient, the operation is simultaneously stabilized. Since the liquid surface level of the operation liquid can be lowered, its rising time can be shortened.

摘要： PURPOSE:To sufficiently exhibit evaporation function while maintaining the level of an operating liquid to the same by providing a cooling unit for every beating equipment, providing the cooling unit with an inner tube wherein an evaporation portion is inserted via an outer tube and a narrow communication gap and constructing by a plurality of pipes communicating upper and lower end portions with upper and lower header tubes. CONSTITUTION:A heating equipment 2 is mounted in a portion partitioned by partitions 1 on each stair (a) of a building. A cooling unit 3 is mounted in adjacent to the heating equipment 2. The cooling unit 3 is constructed such that the upper and lower end portions of several pipes 30 are let communicate with out another by upper and lower header tubes 31 and 32, respectively. The upper and lower header tubes 31 and 32 communicate with pipings 6 and 5 of a vapor phase refrigerant and a liquid phase refrigerant, respectively. Each pipe 30 is composed of an outer pipe 30a, an inner pipe 30b and a small communicating gap 30c therebetween. Since an operating liquid (b) boils in the communicating gap 30c and generated bubbles (c) rise in the communicating gap 30c while rapidly expanding to push up the operating liquid (b), the liquid (b) reaches the upper end of the inner pipe 30b and falls in the inner pipe 30b whereby a stable operation is obtained without a decrease in a thermal conductivity.
