DE2633581A1 - Swimming pool surface solar heating and cleaning cover - with water film ducted to absorb heat and impurities - Google Patents

Abstract

The floating cover for a swimming-pool conducts daytime solar heat to the water, without building up an obstructive heat accumulation, and at the same time removing surface impurities, without any danger of these being later carried back to the water. The film of water to be heated is broken up into fine particles on the surface by the buoyant covering unit (4), or is carried through ducts (1) to the pool edges, and absorbs sun heat and any impurities that eventually arise. There can be a pool side U-shaped channel (5) with shank forming a movable floating flap (3), sucking in heated surface water and impurities, and returning water via a filter.

Description

Swimming pool cover with heat recovery through

Sun exposure and surface cleaning.

The swimming pool cover is primarily used to cover the accumulating during the day Solar heat with the help of a water film 1 or channels 1 through which water flows To supply pool water.

The channel 5 arranged on the long sides sucks the heated and possibly contaminated surface water from and leads it by the shortest route the filter system and the pool water.

During the cooler times of the day and night, the cover prevents the loss of heat of vaporization.

There are previously known covers for the purpose of better absorption are colored black, but here is the one under the cover Heat is not dissipated sufficiently, so that there is a build-up of heat here and none new warmth can be absorbed more. On the other hand, it inevitably results in From all known covers that the surface contamination when you press the System or returned to the pool water when it starts to rain.

The cover consists essentially of a rollable or rigid floating body 4, which is usually also an insulation at the same time and made of welded plastic tarpaulins with an internal foam core (Fig. 2, section AB) or of individual plastic profiles (Fig. 3, section AB) can.

What is new is that the water to be heated is on the surface of the float finely distributed or passed through channels 1.

When exposed to sunlight, it is warmed up and removes any impurities with and flows to the edges of the pool. Here it is from a U-shaped channel 5, the leg on the pelvis side is designed as a movable float flap 3 is taken up and fed back into the pool water via the filter system. For the purpose of Avoidance of evaporation losses is preserved on the surface of the cover flowing water a slide 2 which because of the better absorption of solar heat is colored matt black, for covers colored black a translucent film used.

Claims (1)

Protection claims swimming pool cover with heat recovery through Sun exposure and surface cleaning characterized in that 9 has a serving as a cover floating body 4 the swimming pool water to be heated finely is distributed or directed through channels 1 to the pool edges, where it flows absorbs solar heat through absorption as well as possible impurities, 2) according to claim 1, characterized in that a U-shaped channel 5 is on the water side Leg is formed into a movable float flap 3, on the longitudinal sides of the basin and the heated surface water and impurities sucks in and feeds it back into the pool water via a filter system. 3) according to claim 1 and 2, characterized in that to avoid The water film or the channels are covered by a film 2 from evaporation losses are. For the purpose of favorable absorption is when using a translucent Foil 2 is the top of the floating body 4 in the case of an opaque foil 2 of which Top side colored matt black.
