摘要： PROBLEM TO BE SOLVED: To enhance convenience by making possible to use hot water even if the temperature of hot water in a hot water storage tank is lowered due to overuse thereof. SOLUTION: At the time of hot water supply, a thermistor 14 detects the inner temperature of a hot water storage tank 10. When the detected temperature is higher than a specified level, a decision is made that hot water has been stored sufficiently and hot water is supplied from the hot water outlet 5 of the hot water storage tank 10 through a hot water changeover valve 13 and a hot water supply line 6. When the detected temperature is lower than the specified level, a decision is made that the temperature of water in hot water storage tank 10 is too low and high temperature hot water from a heat source 1 is switched from a heating coil 2 to a passage circulating through a heat exchanger 11 and then low temperature supply water is heat exchanged with high temperature hot water through the heat exchanger 11 before being supplied through the hot water changeover valve 13 and the hot water supply line 6.

摘要： PROBLEM TO BE SOLVED: To obtain an exhaust heat recovering hot water supply system for heating water in a hot water storage tank by circulating heating medium between a gas engine and the hot water storage tank in which dew formation is prevented in an exhaust heat generating unit when the temperature of hot water in the hot water storage tank is low. SOLUTION: A cooling water circulation passage 4 is constituted by coupling a primary heat exchanger 5 disposed in a gas engine 2 with a secondary heat exchanger 6 disposed in a hot water storage tank 12 through a cooling water return pipe 7 and a cooling water supply pipe 8. The cooling water supply pipe 8 is provided with a mixing valve 10 comprising a thermowax valve and a bypass pipe 11 is laid between the cooling water return pipe 7 and the mixing valve 10. When the temperature of hot water flowing through the cooling water supply pipe 8 drops, the mixing valve 10 opens the bypass pipe 11 to feed high temperature hot water from the cooling water return pipe 7 to the cooling water supply pipe 8.

摘要： PROBLEM TO BE SOLVED: To provide a water server for prolonging the life of a germicidal lamp by optimizing the lighting cycle of the lamp without newly installing a sensor for detecting an atmospheric temperature. SOLUTION: In the water server, times Tsw and Tss required to raise the temperature within a set temperature range (6-8°C) within a cold water temperature range (5-12°C) are measured. Corresponding to the measured lengths of times required to raise the temperature, the lighting cycle of an ultraviolet lamp is determined, changed and set, using a relative table. When water is taken therefrom, the measurement is canceled. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a water server in which spreading of bacteria from a tank to a water bottle upon changing the water bottle can be prevented and restrained as much as possible. SOLUTION: In the water server, an ultraviolet lamp is lit until a fixed time of a timer is up (YES at S1, NO at S2, S3), when removing of the water bottle is detected with a removing detecting means. The inside of a cool water tank is sterilized by the ultraviolet irradiation lighting. When the sterilization treatment is finished, the ultraviolet lamp is put out and voice guidance is generated that a new water bottle attachment can be started (YES at S3, S4). Detection of removing may be performed indirectly based on an output of an operation signal of a reset switch to count bottle using days instead of the removing detecting means.

摘要： PROBLEM TO BE SOLVED: To provide a heating method in a storage water heater utilizing a heat pump as a heat source wherein even a remaining hot water fraction impossible to be heated in a prior art method can be heated to the utmost to heat the total amount of hot water in a hot water storage tank. SOLUTION: Average hot water temperature in a storage tank 2 is calculated on the basis of respective detection temperatures by hot water storage temperature sensors 22, 22,.... When the calculated value is lower than set temperature, hot water in the hot water storage tank is stirred and mixed by actuating a circulation pump 42 after a heat pump 3 is brought into a non-actuated state to make the entire hot water temperature uniform, and thereafter the heat pump 3 is actuated to heat exchange and heat the circulated hot water in a circulation passage 41 with a condenser 34. When the calculated value is higher than the set temperature, a low temperature portion (heatable portion) at a lower portion in the hot water storage tank is heated to the utmost.

Circulation outgoing piping to introduce water from a tank bottom part is connected to an end situated upper stream and circulation return piping to return hot water to a tank top part is connected to an end situated downstream to cause a flow of water from below to above. A refrigerant outgoing pipe 51 is connected to the end situated upstream of the refrigerant piping and a refrigerant return pipe 52 is connected to the end situated downstream thereof to cause a flow of a refrigerant for heating from above to below. Water in water piping is heat-exchanged for heating through contact heat transfer at the surface contact part.
