The water-cooled heat exchanger 62 is preferably connected in series with the compressor 52.

Next, the hot water supply unit 70 is installed on a few sidewalls of the bottom surface of the sauna booth A, and includes a heat transfer panel 72 made of a material having a high heat transfer coefficient, and embedded inside the heat transfer panel 72 as a kind of boiler tube. It consists of a sauna heating tube 74, the sauna heating tube 74 is installed to be connected to the hot water unit 60 to circulate the hot water.

At this time, the heat transfer panel 72 may be configured as an ocher block, for example, to further increase the heat transfer effect and the warming effect, and the sauna heating tube 74 is, for example, a copper tube of a person among the sidewalls of the sauna booth A. It is to be buried only below the average sitting height so that most people sitting in the sauna booth (A) and even to increase the sufficient heat transfer effect and warming effect.

Next, the hot air unit 80 is installed between the water-cooled heat exchanger 62 and the electromagnetic expansion valve 56 to allow a heat-cooling condenser 82 and a sauna to exchange heat between the refrigerant and the air of high temperature and high pressure. It consists of an indoor blower including an indoor fan 84 for blowing air inside the booth (A).

In this case, the air-cooled heat exchanger 82 may be connected in series as in the water-cooled heat exchanger 62 from the compressor 52, but the air-cooled heat exchanger 82 and the water-cooled heat exchanger 62 from the compressor 52. ) May be connected in parallel, and a separate auxiliary flow path switching valve (not shown) is installed at the branch point so that the high-temperature, high-pressure refrigerant is divided and supplied from the compressor 52.

Next, the warm air supply unit 90 is connected between the warm air unit 80 and the sauna booth A to supply the warm air generated by the warm air unit 80 to the sauna booth A, but the warm air is collected. The supply pipe 94 through which hot air is supplied from the duct 92 to the sauna booth A and the recovery pipe 96 with which air is recovered from the sauna booth A are connected.

The sauna air conditioning system as described above constitutes a separate flow path through which refrigerant, water and air inside the sauna are circulated, and the refrigerant is the compressor 52, the water-cooled condenser 62, the air-cooled condenser 82, and the electronic expansion. While the water circulates along the valve 56 and the evaporator 58, water circulates along the water-cooled condenser 62, the pump 64, the water tank 66, the sauna heating tube 74, and the air is cooled by the air-cooled type. Passing around the condenser 83, it is circulated along the distribution duct 92, supply pipe 94, sauna booth (A), recovery pipe (96).

At this time, hot water is generated through heat exchange with the water-cooled condenser 62 and circulated to the sauna booth A, while warm air is generated through heat exchange with the air-cooled condenser 82 to the sauna booth A. While the air is blown, the operation of the various components is controlled by a temperature sensor (not shown) installed in the sauna booth A in advance.

Figure 4 is a flow chart illustrating a control method of the sauna air conditioning system according to the present invention, Figure 5 is a graph showing the temperature change inside the sauna booth according to the operation of the sauna air conditioning system according to the present invention.

More specifically, the control method of the sauna air conditioning system according to the present invention will be described with reference to FIG. 4.

The first step is to compare the temperature of the sauna booth (A) with the set temperature set by the user, if the temperature of the sauna booth (A) is lower than the temperature less than 1 ℃ less than the set temperature, generates a warm air sauna booth (A Ventilation inside (see S1, S2)

Of course, a temperature sensor (not shown) is installed inside the sauna booth A, which is connected to a separate control means (not shown) to control the operation of various components.

In more detail, the compressor 52, the indoor fan 84, and the outdoor fan 59 are operated, and thus the refrigerant compressed at a high temperature and high pressure in the compressor 52 is transferred to the water-cooled condenser 62 and the air-cooled condenser. 82, the electronic expansion valve 56, and the evaporator 58, and in the air-cooled condenser 82, the hot air is generated and circulated while the air inside the sauna booth (A) is blown, while the evaporator ( In 58), the outdoor air is blown to evaporate through the heat exchange action with the refrigerant.

At this time, the warm air heat exchanged in the air-cooled condenser 82 is supplied from the distribution duct 92 through the supply pipe 94 into the sauna booth A as the indoor fan 84 is operated, and then the warm air Convection heating and dehumidification are simultaneously performed, and the air inside the sauna booth A is recovered to the distribution duct 92 through the recovery pipe 96.

Of course, as the warm air is supplied into the sauna booth A, the temperature inside the sauna booth A is quickly increased, thereby reaching a target set temperature which is usually set at about 50 to 60 ° C. over a short time. .

In addition, when the indoor air of a predetermined space is blown through the separate ducts instead of the outdoor air to the evaporator 58, the cold heat exchanged in the evaporator 58 is separated as the outdoor fan 59 is operated. It may be guided through the duct to implement convection cooling by the cold air.

Next, in the second step, the warm air is supplied to the sauna booth A in the first step, and at the same time, hot water is heated and circulated into the sauna booth A (see S3).

Of course, the sauna booth A may be heated by warm air, and then the sauna booth A may be heated simultaneously by the warm air and hot water, or may be heated only by the warm water.

At this time, even if the temperature inside the sauna booth A rises due to convection heating due to the warm air, the specific heat of the air is low, so the temperature inside the sauna booth A drops immediately as the hot air supply is stopped. This high hot water allows the temperature inside the sauna booth A to be maintained due to radiant heating.

More specifically, as the pump 64 is operated, water passes from the water tank 66 to the pump 64 and passes through the water-cooled condenser 62, wherein the refrigerant of the high temperature and high pressure of the water-cooled condenser 62 is operated. Heated with hot water through the heat exchange action, and then to heat the bottom and side walls of the sauna booth (A) along the sauna heating tube (74).

Of course, the sauna booth (A) is not only excellent in the heat transfer effect of the heat transfer panel 72, even if the sauna heating tube 74 is disposed only at the height of the average sitting height on the side wall of the hot water that is a large specific heat material As the circulation is excellent, the thermal effect is also excellent, sufficient heating effect can be obtained even if the temperature of the hot water is maintained only 50 ~ 60 ℃.

On the other hand, if the temperature of the sauna booth (A) in the first step exceeds a temperature less than 1 ℃ less than the set temperature, the hot water is heated to circulate inside the sauna booth (A).

Next, the third step is to increase the temperature of the sauna booth (A) during the first and second steps, if the temperature of the sauna booth (A) is lower than the temperature higher than the set temperature 1 ℃, only hot water sauna Allow circulation inside booth A (see S4, S5)

At this time, the compressor 52 and the pump 64 are operated, and thus hot water is generated through heat exchange in the water-cooled condenser 62, and the hot water is supplied to the sauna booth A through the sauna heating tube 74. While the indoor fan 84 is stopped, even though warm air is generated through heat exchange in the air-cooled condenser 82, the indoor fan 84 is not supplied into the sauna booth A.

Therefore, the sauna booth A is heated only by hot water to maintain the warming effect.

As a result, as shown in FIG. 5, when the sauna booth A is convection heated by warm air and radiant heating is performed by hot water at 50 to 60 ° C., the sauna booth can be steamed within 40 minutes to 1 hour. It turns out that the temperature of (A) is heated to about 50 degreeC, and it heated uniformly regardless of the up-down position of a sauna booth (A).
