摘要： PROBLEM TO BE SOLVED: To provide a heat pump water heater that can supply hot water by effectively using the capacity of a hot water storage tank at low power consumption.
SOLUTION: The heat pump water heater comprises a refrigerant circuit connecting, in sequence, compression means 31 for compressing a refrigerant, a main water heating heat exchanger 32, main decompression means 33 and an evaporator 34, and a hot water supply circuit connecting, in sequence, hot water storing means 36, circulating means 37 and the main water heating heat exchanger 32; and has an auxiliary circuit connecting a portion between the compression means 31 and the water heating heat exchanger 32 and a portion between the compression means 31 and the evaporator 34 via a series of switching means 38 and auxiliary decompression means 40. Even when an intake water temperature rises, the refrigerant discharged from the compression means 31 is bypassed to a low pressure side, so that supply water can be easily heated to a high temperature while the discharge pressure and discharge temperature of the compression means 31 are reduced for a safe and efficient heat pump operation.

摘要： PURPOSE:To achieve high efficiency by providing a check valve for allowing refrigerant to flow in a direction opposite to a refrigerant circulation circuit between a four-way valve and refrigerant-water heat exchanger and providing an open/close valve for allowing refrigerant to flow in a direction of the refrigerant circulation circuit, by-passing the four-way valve and check valve. CONSTITUTION:Superheated refrigerant gas of high temperature and pressure delivered from a compressor 1 flows into a refrigerant-water heat exchanger 3 via an open-close valve 7, where water sent from a circulation pump 12 is heated by utilizing condensation heat of refrigerant and the water is stored in a storage tank 11. And pressure of the refrigerant condensed in the exchanger 3 is reduced at a pressure reducing device 4 and the refrigerant flows into an evaporator 5, where it absorbs heat of the atmosphere and is evaporated, which evaporated gas returns to the compressor 1 via the valve 2. When outdoor temperature falls in winter and frost attaches to the evaporator 5 and the temperature of refrigerant passing through the evaporator falls, flow direction of the valve 2 is changed over to a direction of broken line and the valve 7 is closed. As a result, the refrigerant gas delivered from the compressor 1 flows to the evaporator 5 via the valve 2, so that the frost is removed by means of condensation heat.

摘要： PURPOSE:To form warm water and to use for supply of hot water without discarding heat generated by the operation of a cooler by adding a circuit fir supplying supply water to a condenser of the cooler, and switching it to a circuit of coolant. CONSTITUTION:When warm water is generated, first and second motor-driven ball valves 14, 15 are opened, and third and fourth motor-driven ball valves 16, 17 are closed. A fifth motor-driven ball valve 23 is held in a closed state. Thus, a supply water circuit 11 and a warm water supply circuit 12 are conducted with a condenser 2, and supply water is fed externally to the condenser 2. Since a temperature regulating valve 18 throttles the circuit 12 in a predetermined state under the control of a sensor 19 at an outlet side of the condenser 2, the supply water is sufficiently warmed in the condenser 2. The warm water is fed to a hot water storage tank 13 through the circuit 12, and stored in the tank. The warm water stored in the tank 13 is used for showering, hand washing, etc.

摘要： PURPOSE:To prevent temperature of fed-out hot water during a feeding-out of the hot water from being lowered and the temperature of hot water within a hot water storing tank from being lowered when an anti-freezing operation is being carried out and when a defrosting operation is being performed by a method wherein a threeway valve, a pump and a four-way valve are controlled with signals got from a flow rate sensor, a water feeding temperature sensor and a frosting sensor. CONSTITUTION:A three-way valve 17 is arranged within a hot water feeding circuit 9 and near a connecting part with a hot water feeding-out pipe 10. A flow rate sensor 19 is arranged in a water feeding-out circuit 18 branched from the three-way valve 17 to a lower part of a hot water storing tank 7 and in a hot water feeding-out pipe 10. A cold water feeding temperature sensor 13 is arranged in a cold water feeding circuit 9. A frosting sensor 14 is arranged at an evaporator 6. There is provided a controller 20 for use in controlling the three-way valve 17, the pump 8 and the four-way valve 2 with the signals got from each of the aforesaid sensors. when the hot water is fed out, the three-way valve 17 is changed over in such a way that the hot water feeding circuit 11 and the cold water feeding-out circuit 18 are communicated to each other by a flow rate sensor 19. During an anti-freezing operation, the pump 8 is controlled to have the minimum flow rate by a cold water feeding temperature sensor 13 and at the same time the three-way valve 17 is changed over and in turn when the defrosting operation is started to operate, the controlling operation for changing-over the four-way valve 2 and the three-way valve 17 with the frosting sensor 14 is carried out by the frosting sensor 14 with the controller 20.

摘要： PURPOSE:To prevent a pump circulating circuit from being freezed by a method wherein in the case that a hot water temperature within a hot water storing tank acting also as a hot water boiler is low, the hot water within the hot water storing tank also acting as the hot water boiling and the hot water stored in an exclusive hot water storing tank are replaced from each other so as to be applied as a heat source for the defrosting operation of an entire hot water storing tank. CONSTITUTION:Hot water in the hot water storing tank 11 also acting as a hot water boiler of a hot water storing unit is utilized so as to perform a defrosting operation of the outdoor heat exchanger 70. At this time, the hot water temperature within the hot water storing tank 11 also acting as the hot water boiler is detected by a temperature sensing means 31. In the case that the detected temperature detected by the temperature sensing means 31 is lower than the predetermined temperature, the connecting means 51 controls the replacing means 55, the hot water in the hot water storing tank 11 also acting as the hot water boiler having the heating means 14 and the hot water within the hot water storing tanks 12, 13 exclusively operated to accumulate hot water not having any heating means 14 are replaced from each other, and then the entire hot water storing tanks 11, 12 and 13 are applied as a heating source for the defrosting operation. With such an arrangement, it is possible to prevent the pump circulating circuit from being freezed.

摘要： PURPOSE:To provide a substantial reduction of a manufacturing cost or an installing cost, set a substantial small-sized device and reduce a running cost as much as possible by a method wherein a triple-layered pipe type heat exchanging coil of a water heat exchanger is wound around a heat accumulating hot water storing tank. CONSTITUTION:A plurality of turns of triple-layered heat exchanging coil Z for a water heat exchanger are wound around an upper outer circumference of a hot water storing tank 7 and installed there. The triple-layered heat exchanging coil Z is constructed such that water heat exchangers and heat transfer pipes are arranged outside and inside a refrigerant pipe disposed at the water heat exchangers, and a hot water feeding and circulating circuit and a bath circulation circuit are completely independent with a refrigerant flow passage of one system being held therebetween. One heat pump device provides main seven functions of a hot water feeding, a cooling and hot water feeding, an air heating and hot water feeding, a cooling and a bath additional boiling, a heating and a bath additional boiling, (a temperature keeping), a cooling and a heating. Heat radiation while the hot water fed out of an outlet of the water heat exchanger is returned back to an upper part of a hot water storing tank for accumulating heat can be restricted as much as possible.
