First, the distributor 10 functions to distribute the number of heating water or cooling water to the cooling / heating pipe P installed in any one of the indoor floor, the wall, or the ceiling of the individual house, and is similar to the structure of a typical air conditioner / distributor Do. The pipe P may be installed in a cooling / heating panel (not shown), or may be embedded in a floor or a wall.

Next, the heating boiler 20 functions to heat the heating water, and any of the heating boilers for normal heating may be used.

The cooling heat exchanger (30) serves to cool the cooling water by using tap water supplied through the water supply as a cooling source. Instead of tap water supplied as a cold source of the cooling heat exchanger 30, ground water developed in each region or each household may be used.

Next, the cooling / heating water supply line 40 functions to supply cooling water or heating water to the distributor 10, and includes a cooling / heating water supply pipe 41 connected to the distributor 10, A cooling water supply pipe 42 for supplying cooling water cooled by the cooling heat exchanger 30 to the cooling / heating water supply pipe 41, a cooling water supply pipe 42 for supplying heating water heated by the cooling water supply pipe 41 to the cooling / (43) are connected to each other in a T-shape.

The cooling / heating water supply pipe 41 is selectively connected to the heating water supply pipe 42 or the cooling water supply pipe 43 between the cooling / heating water supply pipe 41 and the heating water supply pipe 42 and the cooling water supply pipe 43 And a first cooling / heating switching valve (44) for connecting the first heating / The first cooling / heating switching valve 44 connects the heating water supply pipe 42 to the cooling / heating water supply pipe 41, and when cooling, the cooling water supply pipe 43 is connected to the cooling / Connect.

The cooling / heating water return line 50 functions to return cooling water or heating water from the distributor 10 and includes a cooling / heating water return pipe 51 connected to the distributor 10, And a cooling water supply pipe (53) for returning the cooling water from the cooling / heating water pipe (51) to the cooling heat exchanger (30) Are connected to each other in a T-shape, and a cooling pump 53a for forcibly circulating the cooling water is provided in the cooling water recirculation pipe 53.

The heating water recirculation pipe 52 or the cooling water recirculation pipe 53 is connected between the cooling / heating water recirculation pipe 51 and the heating water recirculation pipe 52 and the cooling water recirculation pipe 53, Conditioning switching valve 54 for selectively connecting the first air-conditioning switching valve 51 to the second air-conditioning switching valve 54 is provided. The second cooling / heating switch valve 54 connects the cooling / heating water return pipe 51 with the heating water return pipe 52 during heating, and connects the cooling / heating water return pipe 51 to the cooling water reception pipe 53).

The heating water circulated through the heating / cooling water pipe 51 and the heating water pipe 52 is heated by the boiler 20 and then supplied through the heating water pipe 42 and the cooling / (41). The cooling water recovered through the cooling / heating water pipe 51 and the cooling water pipe 53 is cooled by the cooling heat exchanger 30 and then supplied to the cooling water supply pipe 43 and the cooling / 41 to the distributor 41.

The cooling water supply pipe 43 and the tap water supply pipe 71 are connected to the lower end of the heat exchanger 30 and the cooling water supply pipe 53 and the tap water transfer pipe 72 are connected to the heat exchanger 30, respectively. This is because the convection action of the fluid causes the hot water to rise up and the relatively cold water to descend.

The water tank 60 temporarily stores the tap water discharged from the heat exchanger 30 and supplies the tap water to the living water. At the upper end of the water tank 60, a tap water discharge pipe (61). The water discharge pipe 61 prevents water from overflowing onto the water tank 60 even when a floating valve installed in the water tank 60 fails.

Preferably, the water tank 60 is located at a higher level than the wash basin, the sink, the washing machine, the toilet, or the like so that the tap water stored therein can be discharged into the drinking water by the self water pressure. When the cooling is not performed, the tap water filled in the water tank 60 is exhausted to the drinking water, and the water tank 60 becomes empty.

Next, the tap water drain line 70 is connected to a tap water supply pipe 71 for supplying tap water to the heat exchanger 30, and a tap water transfer pipe for transferring tap water discharged from the heat exchanger 30 to the water tank 60 A pipe (72), and a domestic water discharge pipe (73) for discharging domestic water in the water tank (60). The tap water transfer pipe 72 is provided with a flow rate regulating device 72a for controlling the flow rate of tap water and a check valve 73a for preventing back flow of tap water is installed in the domestic water discharge pipe 73 Do.

The flow rate regulator 72a controls the flow rate of tap water delivered to the water tank 60 in response to the signal from the controller 80. [ For example, by controlling the diameter of the tap water transfer pipe (72), a small amount of tap water flows into the water tank (60) only at the time of cooling operation. The flow rate regulating device 72a may be installed in the tap water supply pipe 71. A drain pump (not shown) may be installed in the living water discharge pipe 73 as required.

In this case, the tap water inlet pipe 71 is connected to the tap water inlet pipe 74, and a tap water pipe pipe 74 is provided between the tap water inlet pipe 74 and the tap water transfer pipe 72, (75) and a T-shaped valve (75a) for interrupting the operation of the valve. The living water discharge pipe (73) is joined to the tap water transfer pipe (72) and then branched to the domestic water supply pipe (76). The domestic water supply pipe 76 supplies domestic water to a sink, a sink, a washing machine, a toilet, and the like.

In the case of the first embodiment, when domestic water is used during cooling, tap water having passed through the heat exchanger 30 is discharged to the domestic water supply pipe 76 through the tap water transfer pipe 72. However, when the domestic water is not used during the cooling, the tap water passing through the heat exchanger 30 is stored in the water tank 60 through the tap water transfer pipe 72. When the cooling water is not used or the amount of domestic water used is larger than the amount of tap water passing through the heat exchanger 30, the tap water stored in the water tank 60 flows into the domestic water discharge pipe 73 and the tap water transfer pipe (72) and discharged into the domestic water supply pipe (76).

In this case, the water tap water supply pipe 71 is branched into a T shape at the sink water supply pipes 77A and 77B and the living water discharge pipe 73 is joined to the washing machine water supply pipes 78A and 78B in a T shape . Therefore, when cooling is performed, the flow regulating device 72a is adjusted so that the tap water passing through the heat exchanger 30 is stored in the water tank 60 and supplied to the washing machine through the domestic water discharge pipe 73, The flow regulating device 72a is shut off and the tap water is directly supplied to the washing machine through the washing machine water supply pipes 78A and 78B.

FIG. 3 shows a third embodiment of the present invention in which the distributor 10 is installed in a boiler room. In this case, the water tap water supply pipe 71 is branched into T-shape at the first and second washing machine water supply pipes 79A and 79B, and the tap water transfer pipe 72 is branched by the third washing water supply pipe 79C And is connected to the second washing machine water supply pipe 79B and the living water discharge pipe 73 is joined to the second washing machine water supply pipe 79B in a T shape.

Therefore, when cooling is performed, tap water having passed through the heat exchanger 30 is directly supplied to the washing machine through the third washing machine water supply pipe 79C and the second washing machine water supply pipe 79B, or stored in the water tank 60 And is supplied to the washing machine through the domestic water discharge pipe (73). When not cooling, the tap water supply pipe 71 and the flow rate control device 72a are shut off, and tap water is supplied directly to the washing machine through the washing water supply pipe 78B.

Finally, the control unit 80 controls the distributor 10 according to a preset temperature. To this end, a room temperature controller (81) is installed in the room where the cooling / heating pipe (P) is installed, and a dehumidifier may be installed if necessary. The structure and function of the control unit 80 are the same as those of a conventional controller for cooling and heating.
