This solar pond is exposed to outdoor pool wall should carry out heat insulation maintenance, and thermal insulation layer (6) is made of light heat insulation material.The pond face can adopt adds a cover transparent cover plate, and the floating polyethylene that is equipped with many apertures, polypropylene film etc. strengthen the measure of heat accumulation effect.

This solar pond can be by dress gravity flow hot-water heating system.Its structure such as Fig. 2.The bottom of solar pond hot water layer, one boiler (9) is set, be communicated with running water pipe by a coiled pipe (8) that is laid on the hot water layer, running water will become hot water through coiled pipe (8), boiler after (9), the hot water of the gravity flow by can obtaining having pressure behind outlet pipe (10), the tap (11).

This solar pond has jumbo thermal source and low-temperature receiver in the natural state of cooling, and refrigerating plant simple in structure can be set.

Fig. 3 is the structural representation of many absorption type refrigerating units of setting up with the dwelling house solar pond.Consult " motor engineering handbook " 38-5 page or leaf that motor engineering handbook editorial board edits.This device comprises generator (12), rectifier (13), condenser (15), tube connector (16), absorber (17), evaporimeter parts such as (18).Generator is arranged in the hot water layer of solar pond, and it is low-temperature receiver that condenser, absorber are arranged in tank, because directly under water, these parts can be made the form of coiled pipe or straight tube simply.Whole device can be done smallerly, can make the structure of global formation with metal or plastics.Plug through walls (14) is used for the connection at generator (12) two ends and absorber (17) two ends and the connection at evaporimeter (18) two ends.Evaporimeter is positioned at outside the tank, and its structure is the same with common evaporimeter, and rectifier climbs over or passes partition wall and is connected with condenser.

Many advantages of removing with the dwelling house solar pond of the present invention with general solar pond, it is simple in structure, be subjected to sunshine area bigger, cost is lower, the life-span is long, be fit to existing house architecture form, holding concurrently is the gatherer of solar energy, big capacity holder, heating device, the nature cooler, can also carry out solar refrigeration, have good anti-freezing property, daytime, at night, overcast and rainy and winter of less fate can both use, operation and maintenance is convenient, no power consumption parts can provide gravity flow hot water, also use the comfortableness and the economy that can improve dwelling house significantly with other conservation measures.
