摘要： PURPOSE:To produce cold water efficiently using waste heat and prevent environmental pollution by supplying waste heat recovery hot water passing through the waste heat recovery part of an internal combustion engine and the condenser of a compression type freezer, to the adsorbent filling part as a recovery pot which is separated into one part of a multitude unit of adsorption regeneration pots in an adsorption type freezer for normal operation adsorption regeneration pots, and the other part for auxiliary adsorption regeneration pots. CONSTITUTION:An adsorption type freezer A has a multitude of adsorption regeneration pots 20 consisting of a pair of adsorbent filling parts and one is a normal operation adsorption regeneration pot U and the other is an auxiliary adsorption regeneration pot V. The waste heat from an internal combustion engine 1 to operate a compression type freezer C passes a waste heat recovery part 6 and is recovered by the hot water in a waste heat recovery hot water system H. Also, the heat from a condenser 8 in the compression type freezer C is recovered by the hot water in the waste heat recovery system H and is supplied to the adsorption type freezer A, flows in the adsorbent filling part operating as a regeneration pot in the adsorption regeneration pots U and V, and is utilized for adsorbent. In the case the waste heat generated in the internal combustion engine 1 and that in the condenser 8 in the compression type freezer C is larger than the heat necessary for producing cool water in normal operation, the auxiliary adsorption regeneration pot V is used together.

摘要： PURPOSE:To perform a cold heat accumulation, a thermal accumulation at a desired time and to enable a cooling and both cooling and heating to be carried out without operating a compressor at any time by a method wherein a bypassing pipe communicating with a high pressure liquid pipe and a suction pipe of a reversed Carnot cycle is provided with a low pressure liquid acceptor filled with cold heat accumulation material, thermal medium is circulated through the low pressure liquid acceptor and then cold heat is accumulated and then the thermal medium in the low pressure liquid acceptor is circulated through an evaporator. CONSTITUTION:In a reversed Carnot cycle, a bypassing pipe 17 for communicating between a high pressure liquid pipe 12 and a suction pipe 16 is provided. A low pressure type liquid acceptor tank 21 is connected at a connecting intermediate part between a liquid pipe 18 branched from a high pressure liquid pipe 12 and a liquid pipe 18. Cold heat accumulation material 22 is stored in the liquid acceptor tank 21. A liquid pump 23 is connected to a circulation pipe 24 and a spray 25. A supplying pipe 26 connected to a liquid pump 23 is connected between an expansion valve 3 and one end of an evaporator 4. A return pipe 28 is connected to a three-way valve 14. Thermal medium from the compressor 1 is circulated through the low pressure liquid acceptor 21 to a suction side and then cold heat is accumulated. The thermal medium is circulated by a liquid pump 23 to the evaporator 4 to perform a cooling operation. The cold heat accumulation is performed at a desired time, the cold heat accumulated at any time is utilized and then a cooling operation is carried out.

摘要： PURPOSE:To simplify the constitution of a piping system, to improve the energy efficiency, and to reduce the equipment cost and running cost by a method wherein cooling operation is effected through utilization of high pressure refrigerant liquid after defrost operation is effected without effecting cooling operation through introduction of refrigerant liquid directly to each cooler. CONSTITUTION:Without introduction of a refrigerant for cooling directly to coolers 4a and 4c, through utilization of a first line 11a, high pressure refrigerant liquid for defrost is introduced to the cooler 4a to perform defrost operation. After the defrost operation, refrigerant liquid overcooled by defrost is introduced through the outlet side of the cooler 4a to another cooler 4b and the other cooler 4c through utilization of a second line 12a, and cooling operation is effected through utilization of overcooled refrigerant liquid. By orderly switching lines 11a and 12a at each of the cooler 4a and 4c, defrost operation and cooling operation can be effected simultaneously with each other, and constitution of the line is simplified. By introduction of high pressure refrigerant liquid to the coolers 4a and 4c through an expansion valve 13a, the high pressure refrigerant liquid is overcooled and enthalpy is increased. Thereby, cooling efficiency and freezing efficiency at an after-process are further increased.

摘要： PURPOSE:To enable a large amount of particle ices having a uniform diameter to be easily and continuously manufactured by a method wherein a lower part of a hydrophobic nonfreezing fluid filling region having a cooling means capable of cooling nonfreezing fluid to be lower than its icing point is provided with an injection member having several nozzle opening and a flow-divider is arranged at an upstream side of the injection member. CONSTITUTION:An injection member 4' having several nozzle openings and provided with a heater 40 is arranged at a lower part of a hydrophobic nonfreezing fluid filling region 3 having a cooling pipe 6 capable of cooling nonfreezing fluid lower than its icing point. In turn, a flow-divider 41 is connected to an upstream side of the injection member 4' through a tube 42 in such a way as a water pressure for each of nozzles 5 becomes uniform. Water can be supplied to the nonfreezing fluid filling region 3 through the injecting member 4' with the flow-divider 41. With such an arrangement as above, the particle ices are manufactured while the water is being directly heat contacted with the hydrophobic nonfreezing fluid. With such an arrangement as above, it is possible to manufacture a large amount of ices of uniform spherical shape having a high heat removal efficiency.
