Abstract

PURPOSE:To permit the reduction of an initial cost as well as a running cost, by a method wherein warm water for radiation heating is utilized for the warm water for a swimming pool while heating systems and the control systems for both of the warm water are combined into one system. CONSTITUTION:The floor surface of a pool side is constituted of a radiation panel 3, into which warm water coils 3a are embedded, and warm water, heated by a heater 7, is supplied into a warm swimming pool 1 after effecting heat exchange between the floor surface. The warm water, which overflows from the pool 1, is returned into a regulating tank 4 through side grooves 2 and the warm water is passed through the heater 7 to reheat it, thereafter, is circulated through the warm water coils 3a. The heating system for the indoor warm swimming pool can be combined into one system for both of indoor heating and warm water for the pool and heat sources or control systems can be combined into one unit, therefore, an installation cost therefor may be reduced and costs for management and maintenance thereafter may become inexpensive.

Description

DETAILED DESCRIPTION OF THE INVENTION <<Industrial Application Field>> The present invention relates to a poolside floor heating system in a heated pool, and particularly to a heating system that aims to effectively utilize the amount of heat retained in hot water.

<<Conventional technology>> In physical education facilities such as public gymnasiums and athletic gyms that are equipped with indoor heated pool equipment, the water temperature of the pool is adjusted to allow swimming throughout the year, and efforts are made to make effective use of the facility, especially in the winter. Therefore, the design focuses on indoor heating equipment.

One of these heating devices has a heating coil buried in the poolside floor or the pool indoor ceiling.
There is a method in which hot water is circulated through the coil to heat the room through the floor and ceiling.

This method uses radiant heat from the floor or ceiling for heating, making it possible to provide highly comfortable heating while saving energy.

≪Problems to be solved by the invention≫ However, with this radiant heating system, conventionally the heating system is two systems for pool hot water and heating hot water, which results in high construction costs and requires separate heat sources and control systems. However, management and maintenance costs were also expensive.

This invention was made in view of the above problems, and by using hot water for radiant heating as pool hot water, the heating system and control system for both hot water are integrated into one system, thereby reducing initial cost and running cost. The aim is to reduce both levels.

<Means for Solving the Problems> In order to achieve the above object, the present invention comprises a radiant panel in which a hot water coil is embedded in the poolside floor surface, and hot water heated by a heater is supplied to the hot water pool. In doing so, the hot water is supplied into the pool after exchanging heat with the floor surface, and the hot water that overflows from the pool is returned to the adjustment tank through the gutter, and the hot water is passed through the heater to be reheated. The feature is that the water is circulated within the hot water coil.

≪Operation≫ The hot water that has passed through the heating coil produces a large heat drop between the inlet and outlet temperatures depending on the heat exchange efficiency of the radiant panel, so the hot water after heat exchange reaches a temperature suitable for the water temperature in the pool. Descend. Therefore, the temperature difference between the entrance and exit of the heating coil can be kept relatively large, and stable operation of the heat source can be achieved.

<<Example>> Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

The figure shows a heated pool and a poolside floor heating system according to the present invention.

In the figure, 1 is a heated pool, 2 is a heated pool 1
Side grooves 3 are formed at the foot of the pool, and 3 is a radiant panel that forms the poolside floor surface.

In the hot water pool 1 and the radiant panel 3, water stored in an overflow adjustment tank 4 is pumped through a pump 5,
The water is supplied through the filter 6 and heated by the heater 7 through the main supply pipe 8, and depending on the switching operation of the switching valve 9, it is supplied to the hot water coil 3a side or through the pool supply pipe 10. The water is directly supplied into the pool 1 from the discharge port 10a that opens into the pool 1.

Further, a second switching valve 11 is disposed between the discharge side of the hot water coil 3a and the pool supply pipe 10, and by switching the switching valve 11, heat is exchanged by the hot water coil 3a. Either supply the drain water into the pool device or use the main drain pipe 1.
A selection switching operation is performed to discharge to the second side.

Further, water overflowing from the water surface of the pool 1 is discharged from the side gutter through a discharge pipe 13 connected thereto to the main discharge pipe 12 side, and is circulated and discharged into the overflow adjustment tank 4 through this main discharge pipe 12. It's summery.

Therefore, by switching the switching valve 9 and the second switching valve 11, the following selection operations are performed.

The hot water heated by the heater 7 is circulated directly through the hot water coil 3a of the radiant panel 3 and into the overflow adjustment tank 4 through the main discharge pipe 12.

Hot water heat-exchanged by the hot water coil 3a is supplied into the pool 1.

Hot water heated by a heater 7 is directly supplied into a pool 1 without passing through a radiant panel 3.

Each of the switching valves 9 and 11 is, for example, an electromagnetic switching valve, and a selective switching operation is performed in accordance with the control output of a valve switching device 14 and a control section 15 that controls switching control.

The output ends of a water temperature sensor 17 provided within the pool 1 and a bed temperature sensor 18 provided at appropriate positions within the floor surface are input to input ends of the control unit 15, respectively.

In addition, the control unit 15 controls these sensors 17 and 18.
A switching drive signal is outputted to the valve switching device 14 in accordance with the detected output, and heating control is performed on the heater 7.

That is, the control unit 15 controls each of the sensors 17 and 18.
Each valve 9, 1 based on the temperature information output from
1 and heating the heater 7. For example, when the bed temperature is low, the valves 9 and 11 are connected to the hot water coil 3a, the main supply pipe 8 and the main discharge pipe 1.
2, and the heater 7 is set at a relatively high temperature. Further, under normal conditions, hot water is supplied into the pool 1 while passing through the hot water coil 3a with the heater 7 set at a relatively low temperature. Alternatively, if floor heating is not required, control is performed to bypass the radiant panel 3 and directly send hot water to the pool 1.

In addition, when supplying hot water that has undergone heat exchange through the hot water coil into the pool 1, the radiant panel 3
The temperature drops due to thermal error according to the heat exchange efficiency of
Further, since the inside of the pool is filled with a large volume of water with high specific heat, extreme temperature changes do not occur inside the pool 1.

<<Effects of the Invention>> As explained in detail in the embodiments above, according to the present invention, the heating system for an indoor heated pool can be combined into one system for indoor heating and for hot water, and the heat source and control system can be combined into one system. Since they can be made the same, construction costs can be reduced, and subsequent management and maintenance costs can also be reduced.
