摘要： PURPOSE:To make it possible to supply hot water or cold water extremely in a short time by heat exchanging liquefied refrigerant with gasified refrigerant perfectly in an opposed current, installing a heated fluid penetration passage to a condenser, and a cooled fluid penetration passage to a vaporizer respectively, and making heated fluid refrigerant inside the vaporizer to flow counter. CONSTITUTION:A refrigerant liquefied gas heat exchanger 11 is installed in an attempt to heat exchange liquefied refrigerant from the outlet of a condenser 2 to an expansion valve 3 with gasified refrigerant from a vaporizer 4 to a compressor 1. The compressor 1, when driven, raises insulation compressed enthalpy i1' to i2'. Then, the refrigerant is heat exchanged with heated hot water in the next condenser 2, cooled under a constant pressure state, and turns into liquefied refrigerant. When further cooled, i3' under an excess cooling state is obtained. The route of heated hot water is formed based on an once through flow. Moreover, heat exchange is made with the refrigerant in a counter flow. Therefore, the refrigerant is cooled by fresh heated hot water constantly supplied, which equalizes the logarithmic mean temperature difference of the both with a lager value. Moreover, as for the outlet of a refrigerant condenser 2, excess cooling can be more effective by the heat exchange made by the heated hot water which flows in at an ambient temperature.

摘要： PURPOSE:To facilitate the manufacture of the tilted heat transfer pipe and to improve the liquid vaporizing efficiency thereof by a method wherein wies on a liquid boiling and vaporizing wire fin pipe of a liquid filling type cooler are corrugated and the tops of the resultant convex sections of the corrugated wires are depressed so that tunnels are formed between the base pipe and the wires and among the convex sections of the wires. CONSTITUTION:A number of rows of corrugated wires are wound about the base pipe (A) in such a manner that the convex sections 2 of the corrugated wires 1 are aligned with one another or held staggered in an alternative fashion and the bottoms 3 of the corrugated wires 1 are fusion-bonded to the outer peripheral surface of the base pipe (A) so that the tunnels (a) are formed between the base pipe (A) and the wires 1. Next, the tops of the convex sections of the wires and therearound are depressed by a high speed rotary grinder to make the parts of the wires near the convex sections jut out as at 4 with the formation of small holes (b) among the jutouts 4. With the above structure, the small holes (b) of a configuration required for effecting boiling and vaporization of the liquid can be formed accurately and easily to thereby improve the liquid vaporizing efficiency of the heat transfer pipe.

SOLUTION: In a heat pump for supplying hot-water, a compressor 1, a condenser 5, a refrigerant expansion valve 6a and an evaporator 3 are connected sequentially through a refrigerant pipeline while a hot-water storage tank is connected to the condenser 5 of the heat pump, provided with a four-way valve 2 arranged at the discharging side of the compressor and an accumulator 8 arranged at the suction side of the compressor, to circulate water in the hot-water storage tank into the condenser 5 and raise the temperature thereof to obtain hot-water for supplying. In this case, a refrigerant control circuit, branched from the half-way of a pipeline from the condenser 5 to a refrigerant expansion valve 6a and arriving at the evaporator 3, is provided so as to be switchable through a changeover valve 7 while a refrigerant buffer 17 is arranged in the control circuit to switch the changeover valve 7. The discharging of low-temperature hot-water or high-temperature hot-water can be effected by a method whether the hot-water is passed through the refrigerant buffer 17 or not.

摘要： PROBLEM TO BE SOLVED: To prevent flooding of a refrigerant by a method wherein the piping on the high temperature side of a water heat-exchanger is coupled directly to a heat storage water tank, a piping on the low temperature side is coupled to the heat storage water tank through a load part, and a bypass piping is arranged throughout a piping between a piping running between the load part and the heat storage water tank and the piping on the high temperature side. SOLUTION: An air heat-exchanger 4, a heat-exchanger 6 using a heating medium, such as brine, a heat-exchanger 7 using water, and an accumulator 11 are coupled through a refrigerant piping to form a fundamental circuit. The heating medium piping of the heating medium heat-exchanger 6 communicates with a heat storage water tank 21 through a circulation circuit and the piping on the high temperature side of the water heat-exchanger 7 is coupled directly to the heat storage water tank 21. Further, a piping on the low temperature side is coupled to the heat storage water tank 21 through a load part, and a bypass pipe between a piping, running between the load part and the heat storage water tank 21, and the piping on the high temperature side. This constitution prevents flooding of a refrigerant.
