Swimming Pool Solar Project

Element of Solar Pool Heating System:
1. Solar Collector: The device through which pool water is heated by the sun
2. Filter: Removing debris before water is pumped through the collector
3. Pump: Circulate water through the filter and collector, then back to the pool
4. Flow Control Valve: Automatic or manual device that diverts pool water through the solar collector.

Swimming Pool Solar System Work Theory:
Pool water is pumped through the filter, then through the solar collectors, where it is heated before returning to the pool. In hot climates, the collectors can also be used to cool the pool water during peak summer months by circulating the water through the collectors at night.
Some systems include sensors and an automatic or manual valve to divert water through the collectors when the collector temperature is sufficiently higher than the pool temperature. To compare with, when the collector temperature is similar to the pool temperature, filtered water simply bypasses the collectors and returne to the pool.

Different Types:
Swimming pool solar collectors can be made of different material. The type you'll need depends on the climate and the way you intend to use the collector. If you'll only use your pool when temperature is above freezing, then you'll probably only need an unglazed collector system. Unglazed collectors don't include glass covering (glazing). They are generally made of heavy-duty rubber or plastic treated with an ultraviolet (UV) light inhibitor to extend the life of the panels. Because of their inexpensive parts and simple design, unglazed collectors are usually less expensive than glazed collectors. These unglazed systems can even work for indoor pools in cold climates if the system is designed to drain back to the pool when not in use. Even if you have to shut the system down during cold weather, unglazed collectors may be more cost effective than installing a more expensive glazed collector system.
Glazed collector systems are generally made of copper tubing on an aluminum plate with an iron-tempered glass covering, which increases their cost. In colder weather, glazed collector systems with heat exchangers transfer solar heat more efficiently than unglazed systems. Therefore, they can be used year-round in many climates.
Both glazed and unglazed collector systems should include freeze protection if they'll be used in colder conditions.
