摘要： PURPOSE: To avoid lowering in the coefficient of performance by keeping a cooling pipe at a wall temp. below 0 deg.C when a part of water continuously flowed from a heat storage water tank to the cooling pipe is returned to this tank, and applying ultrasonic waves to the inside of this cooling pipe to remove grown ice needless from the pipe wall. CONSTITUTION: A cooler 3 is set outside a heat storage water tank 1 with a water feed pipe line 4 connected to an intake 18 of a cooled water feed chamber 14 and return pipe line 23 connected to an ice-contg. water outlet 19 of a liq. collector chamber 15. Cooling water is fed to a condenser 7 to deprive a high pressure coolant drained from a compressor 6 of heat to condense this coolant which is then restricted by an expansion valve 8 and discharged to gasify in a coolant vessel 10, thereby cooling a cooling pipe 11 to a temp. below ice point. An ultrasonic oscillator element 20 irradiates an ultrasonic wave on the cooled water flowing in the cooling pipe 11 to grow needle ice crystals of the cooled water on the pipe wall due to the condensing action of this wave and remove the ice needles grown to specified size from the wall due to the cleaning action of the ultrasonic wave.

摘要： PURPOSE: To provide an air source type unit air conditioning system which can flexibly cope with various heat loads. CONSTITUTION: The air source type unit air conditioning system comprises a heat source unit having a central heat source facility 1, and a first heat exchanger 21 for recovering cold heat from the facility via first heating medium to heat exchange it with supply air into a room. Further, the unit has second heat exchangers 22, 23 for heat exchanging second heating medium circulating in a heat pump circuit with the supply air into the room, a third heat exchanger 24 for heat exchanging the second medium circulating in the pump circuit with third heating medium circulating in an exhaust heat circuit, and a vapor-liquid contact type fourth heat exchanger 26 for heat exchanging the third medium circulating in the exhaust heat circuit with exhaust air from the room. Since the second and third exchangers are so constructed as to be selectively functioned as condensers or evaporators in response to an operating mode, it can flexibly cope with various cooling/heating loads.

摘要： PURPOSE: To reduce a heat transferring power and also reduce a capacity of a heat source device or a capacity of an electrical power facility by a method wherein a heat exchanger in a heat pump circuit having a heat accumulative tank circuit and a heat discharging circuit integrally assembled is operated as either a condensor or an evaporator in response to an operation mode. CONSTITUTION: A heat source device 10 comprises a heat accumulative tank circuit having a respective heat accumulative tank ST and having a first heat medium such as heat accumulating water circulated therein; a heat pump circuit having both a compressor COMP and an expansion valve EV and also having second heat medium such as refrigerant circulated therein; a first gas-liquid contact type heat exchanger EX1; and a heat discharging circuit having a third heat medium such as cooling water or the like circulated therein. The heat pump circuit operates a third heat exchanger EX3 as an evaporator during an ice heat storing mode and further operates a seventh heat exchanger EX7 as a condensor. In addition, during a hot water heat storing mode, a sixth heat exchanger EX6 is operated as an evaporator and then the third heat exchanger EX3 is operated as a condensor.

摘要： PURPOSE:To realize a stable operation of an ice heat accumulation system for use in storing a heat source for air conditioning operation within a heat accumulation tank in a form of ice by a method wherein a maintenance work for the system is simplified and made easy and occurrence of water level difference between each of the heat accumulating tanks of communicating type is prevented. CONSTITUTION:A water taking chamber 11 having particle filtering material 13 layed thereon is arranged within a water taking tank 5. Since water taking operation for water for a heat source to be supplied to a supercooling device 16 is carried out through the filtering material 13, ice uncleus are not mixed within the supercooling device 16. Ice and water slurry generated by supercooled water discharged from the supercooler device 16 is supplied to each of the tanks and stored there. Since many fine holes for trapping ice are formed around a water passing pipe 31 for communicating each of the tanks 6, 7 and 8 to each other, ice within the tank is not adhered inside the communicating part and no layer is formed. Accordingly, no water level difference amy occur between each of the tanks.

摘要： PURPOSE:To provide no restriction on the number of small tanks to be installed in an ice accumulation heat system for employing multi-tank type heat accumulating tanks composed of a plurality of small tanks. CONSTITUTION:Ice and water slurry generated by over-cooled water produced by an over-cooling device 10 are concurrently supplied in parallel against independent small tanks 2, 3, 4 and ice is stored in each of the small tanks. At this time, a variation of water level in each of the small tanks is not high and further ice can be uniformly accumulated within each of the small tanks, resulting in that there is no limitation to the number of small tanks to be mounted and a degree of freedom of installing locations for the small tanks can be increased. In addition, since a changing-over valve and a communicating pipe are not needed, an amount of working operation can be reduced.

摘要： PURPOSE:To manufacture overcooled water stably by a method wherein water is conducted continuously into a header vessel, provided with a multitude of heat transfer tubes arranged vertically and positioned above a cooler, to keep the amount of water in the vessel so sufficient that the inside of the header vessel will never become a negative pressure. CONSTITUTION:Water in a heat accumulating tank 1 is supplied to an overcooler 2 by a pump 3 through a water passage 4 and is discharged into atmosphere from the overcooler 2 as overcooled water 5 having a temperature lower than 0 deg.C, then, is collided against a dispersing plate 6 and overcooled condition is released by the shock of dropping from the dispersing plate 6 whereby the overcooled water becomes fine ices and sherbet type ice 7 is reserved in the heat accumulating tank 1. When a vacuum pressure is produced in the header vessel 11 due to suction effect by dropping water or the inducing of air from the opening end 15 of a heat transfer tube upon the downflow of water, supplied into the header vessel 11 of the overcooler 2, through the heat transfer tube 9, variety is generated in the degree of overcooling of the overcooled water. Accordingly, the amount of water, which is sufficient to maintain the inside of the header vessel 11 at a positive pressure, is poured forcibly and continuously by the pump 3 by pressure whereby freezing can be avoided.

摘要： PURPOSE: To eliminate the possibility of freezing in heat exchanger tubes by controlling temperature to keep the surface temperature from being below a specified value at any point of the surface of the wall of the tubes contacting water in a cooling zone. CONSTITUTION: A refrigerant compressed by a compressor 25 is condensed by a condenser 26 and lets heat radiate. The condensed liquid of the refrigerant is reduced by an expansion valve 27 and then, evaporated being expanded in an evaporator chamber 23 to be circulated to the compressor 25. The expanded evaporation of the refrigerant enables cooling of the heat exchanger tubes 19 in the evaporator chamber 23 from thereoutside. With the compressor 25 in the normal operation, the regulation of the expansion valve 27 allows maintaining of the expansion pressure in the evaporator chamber 23 constantly at a specified value and hence, under the specified pressure, the heat exchanger tubes 19 existing in the evaporator chamber 23 can be cooled to a certain specified temperature simultaneously at any position. This enables easily controlling of the temperature to keep the surface temperature from being below -5.8C at any point of the surface of the heat exchanger tubes 19 during the passage of water through it and supercooled water is continuously taken out at an outlet part 24 to release the supercooled state instantaneously with a supercooled state releasing device 16.
