Abstract

PURPOSE:To allow for a cooling operation without the need of cooling cycle, by cold-storing a low temperature waste heat from the heat collecting heat exchanger of heat pipe type hot water supplying device in a cold-storage tank and by transffering the cold-heat thus stored to an inside cooling heat exchanger during a daytime. CONSTITUTION:A heat collecting heat exchanger 5 is provided in a cold-storage tank 9 in a confronted relation, the cold-storage tank 9 having a low temperature latent heat storing material 8 filled therein. The condensing section 11 of loop type heat pipe 10 is arranged as a heat transferring means inside the cold- storage tank 9. The evaporating section 12' of loop type heat pipe 10 which serves as a cooling heat exchanger 12 is provided in a confronting relation against a fan 13 at an inside place located below the condensing section 11. A cock 14 is provided at the part of intermediate route of loop type heat pipe 10. The low temperature heat energy which is collected inside the cold-storage tank 9 under the operation of heat pump cycle during the midnight is transferred to the inside cooling heat exchanger 12 by the movement of heat transferring means on demand in the morning and daytime. An air inside the room is thus cooled down without the need of cooling cycle.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an air conditioner that uses low-temperature waste heat from a heat pump water heater that uses late-night electricity to perform daytime cooling.

Structure of the conventional product and its problems Is the conventional late-night power heat pump water heater using atmospheric heat more than the heat exchanger (evaporator) for collecting heat? The air that has become low temperature is discharged, and the hot water taken from the atmosphere is released in the heat exchanger for heat radiation to heat the water in the hot water tank. Since the low-temperature air was discarded, it was a big problem in terms of energy savings.

OBJECT OF THE INVENTION The present invention solves these conventional problems by storing the low-temperature waste heat from the heat exchanger of a pump type water heater in a cold storage tank, and storing it in a cold storage tank, so that it can be used as a heat exchanger for indoor cooling during the day. Cooling by conveying all that cold heat to? What to do? purpose.

Structure of the Invention In order to achieve this object, the present invention provides a heat exchanger for collecting heat of a heat pump water heater using late-night electric power, and a cold storage tank for low temperature, and a heat exchanger for indoor cooling. Is there a heat transfer means between the cold storage tank and the cooling heat exchanger? It was established.

With this configuration, the low-temperature energy obtained from the heat exchanger for collecting heat during operation the night before is stored in the cold storage tank, and during the day, the heat is transferred to the indoor cooling heat exchanger by the heat transfer means to cool the room. .

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

Reference numeral 1 is a heat pump type water heater using late-night electricity, which is composed of a compressor 2, a heat exchanger 3 for heat radiation, a capillary tube 4, a heat exchanger 6 for heat collection, a hot water storage tank 6, and a water circulation bomber.

The heat exchanger 5 for collecting heat is disposed inside a cold storage tank 9 in which a latent heat storage material 8 for cold and hot temperatures is enclosed. A condensing section 11 of a loop-shaped heat pipe 10 is disposed inside the cold storage tank 9 as a heat transfer means, and a cooling heat exchanger 1 is installed in a part of the room located below the condensing section 11.
The evaporating section 12'2 of the loop type heat vibrator 10, which is the second loop type heat vibrator, is provided opposite to the fan 13b. Further, a shutoff valve 14 is provided in a part of the intermediate path of the loop type heat vibrator 10. 15 is a pressure reducing reverse valve connected to the hot water storage tank 6, and 16 is a hot water tap connected to the outlet side of the hot water storage tank 6.

In the above configuration, the refrigerant compressed by the compressor 2 loses heat in the heat exchanger 3 for heat dissipation and becomes low temperature, is further depressurized in the capillary tube 4, reaches the heat exchanger 5 for heat collection, and is transferred to the refrigerant tank containing evaporative heat. 9 A-heat is taken from the heat storage material 8 for low temperature sealed inside and sent to the compressor again, which is the same as the above pump cycle? It is something that is repeated. Water is sent from the hot water storage tank 6 to the heat exchanger 3 for heat dissipation by the circulation pump 7, and the water absorbs heat from the heat pump cycle, rises in temperature, returns to the hot water storage tank, and returns to the circulation cycle to raise the water. Go.

Here, the latent heat storage material 8 for low temperature in the cold storage tank 9
Driving late at night? The low-temperature thermal energy stored through the loop-type heat vibrator 10 is released into the evaporator section 1 by opening the on-off tap 14 of the loop-shaped heat vibrator 10 and operating the fan 13 during the day when cooling is required.
When the working fluid sealed inside 2 evaporates and loses the latent heat of vaporization and is condensed and liquefied in the condensing section 11, it is consumed, and the low-temperature thermal energy is transferred from the condensing section 11 to the evaporating section 12.
This has the excellent effect of being able to perform indoor cooling without a dedicated cooling cycle.

In addition, 10 heat vibrator trays with 14 opening/closing valves in the middle are installed to transfer low-temperature energy using a 2-inch indoor cooling heat exchanger and a cold storage tank 9. Moreover, by closing the 14 opening/closing valves when the air conditioner is not being used, the heat transfer tray can be prevented, and any negative effects can be completely prevented when the heat pump is in operation. It is something that you have.

Futa/ Said cold storage tank 91/im Latent heat storage material 8 for cold and hot? By enclosing it, not only can the total volume of the cold storage tank 9 be made very small, but also the cooling operation can be performed at a constant temperature due to the latent heat effect of the latent heat storage material 8, which has a great effect.

Effects of the Invention According to the air conditioner of the present invention, a heat exchanger for collecting heat of a heat pump water heater using late-night electricity is directed into a cold storage tank for low temperatures, and a heat exchanger for indoor cooling is provided, Since a heat transfer means is provided between the tank and the cooling heat exchanger, the low-temperature thermal energy stored in the cold storage tank due to operation of the heat pump cycle late at night can be used to operate the heat transfer means when cooling is required during the day. This device has an excellent effect in that it can be transported to an indoor cooling heat exchanger and can be cooled indoors without using a cooling cycle.
