PURPOSE:To reduce a running cost by a method wherein the roof of the titled swimming pool is provided with an unique function to adjust the amount of solar heat absorbed into the pool and accumulate the excess solar heat into a heat accumulating tank to serve the accumulated heat for heating of warm water in the pool in accordance with the necessity therefor. CONSTITUTION:The roof of the heated swimming pool 5 is constituted by arranging two sheets of upper and lower transparent plastic plates 1, provided with a heat insulating air layer 2, with a space 4. A liquid supplying port 6 is provided at one end of the plastic plate 1 and a liquid discharging port 7 is provided at the other end thereof. Respective plates are connected with the heat accumulating tanks 8, 9 to reserve liquids 10, 11 such as water having different heat absorbing rate, silicone oil or the like therein. When the temperatures of the warm water 12 and an indoor space 13 are lower than a proper tmperature, both of the liquids are not circulated in the plastic plates, therefore, the solar heat permeates through the plastic plates and increases the temperature of warm water and indoor space. When a part of the solar heat is necessary, water 10 is circulated in the upper plastic plate to supply the solar heat to the warm water and the indoor space while the excess heat is accumulated in the heat accumulating tank 8 to effect heat exchange between the warm water if necessary. When it is not necessary to raise the temperatures at all, the colored silicon oil 11, prominent in heat absorption rate, is circulated in the lower plastic plate to accumulate the solar heat into the tank 9 and use it for increasing the temperature of warm water by effecting heat exchange with the warm water. The upper plastic plate 1 serves for temperature keeping and heat insulation. |
