RU2151846C1 - Method for heating and purification of water in swimming pool - Google Patents

Abstract

FIELD: construction, applicable in heating and purification of swimming pools. SUBSTANCE: method consists in water heating and purification operations. For water heating use is made of a solar battery placed outside the pool, connected to the pool through inlet and outlet pipes and producing a circular flow of water, collecting the floating impurities in the upper trap. Heavier impurities are gathered by the bottom water flow in the lower trap. EFFECT: enhanced efficiency of water heating and purification. 2 cl, 1 dwg

Description

 The proposed method of heating and water purification can be used for heating and water purification in swimming pools, showers and other tanks with liquid.

 Known methods of water purification in swimming pools, providing complex self-propelled devices moving along the bottom and walls of the pool, working on the principle of a vacuum cleaner (Patent EP N 0257006, MKI E 04 H 3/20 of 02.24.88, patent EP N 9701689 AE, MKI 6 E 04 H 4/16 dated 1/16/97). The devices are very complex and electrically unsafe.

 Closest to the proposed are a method and apparatus for thermal insulation, as well as heating water by trapping solar heat. The method involves the use of a floating frame, tightened with two heat-insulating films: transparent above, transmitting sunlight, and black below. Between the films air pockets are formed. The use of two films contributes to a more complete conversion of solar radiation into heat and prevents the reverse transfer of heat by water to the surrounding space (Patent FR N 2600697, MKI 4 E 04 H 3/20 of 12/31/87).

 The disadvantage of this method is the low thermal conductivity of the films, resulting in a slow exchange of heat of hot air in air pockets and water, a small area of solar heat collectors, low efficiency of this method of heating water, the need and laboriousness of dismantling the device before bathing during the period of strongest solar radiation (bathing period usually in the afternoon hours).

 These disadvantages are eliminated by the application of the proposed method of heating and water purification. The method involves the use of a solar battery placed outside the pool, which heats the pool continuously, regardless of whether or not swimming in the pool. To increase the efficiency of the battery, the “greenhouse effect” is used, for which the battery is painted black, the floor and the pool wall adjacent to the battery are lined with black thermal insulation material, the remaining walls and ceiling are mounted from translucent material, such as glass.

 SUMMARY OF THE INVENTION

A method for heating and treating water in a swimming pool is proposed, in which a solar battery is used to increase the area of solar heat collection, and to increase the heating efficiency, the solar battery is enclosed with a translucent material. The heating method is especially effective in the middle latitudes of the globe with a continental climate, in particular in Russia. Firstly, the longitude of the day here in the summer months reaches 17 hours. Secondly, more than half of summer days, an anticyclone dominates here with a cloudless sky and cool air. At this time, the temperature in the greenhouses reaches 60-70 ^o C at an ambient temperature of 15-17 ^o C. The water in the solar battery is quickly heated, rises up - circulation begins (see drawing).

 Warm water moves in the upper part of the pool from the battery (1) to the opposite wall, dragging along light pollution floating on the surface (tree leaves, foam, etc.). Contaminants penetrate the grate and fall into the garbage collection (3) - the gutter, from where they are manually removed. Cooling, the flow sinks into the bottom layers and moves in the opposite direction, moving the sunken pollution. Contaminants are collected in the sump (4), from where they are also periodically removed.

 The method is safe, does not require additional energy costs and begins to act with the sunrise, without interfering with the functioning of the pool.

On the figure:
1 - solar battery filled with water;
2 - floating pollution;
3 - trough;
4 - sump.

Claims (2)

 1. A method of heating and treating water in a swimming pool, including heating and treating water, characterized in that a solar panel placed outside the pool is connected to the pool with inlet and outlet pipes and creates a circular stream of water in the pool that collects floating contaminants into the upper trap, and heavier pollution by bottom flow into the lower one.  2. The method according to p. 1, characterized in that in order to increase the heating efficiency, the solar battery is enclosed with a translucent material from above and from the sides.
