By “Super Heating” the refrigerant with the aid of the Solar Collector, we are able to increase the temperature difference between the condenser coil and the ambient temperature. By creating this difference, Sedna Aire is able to utilize the entire coil face at the condenser which allows for a better heat exchange throughout the entire system.
With a greater heat exchange, Sedna Aire is able to not only reduce the temperature in the conditioned space but also maintain better humidity control which makes the space more comfortable at a higher temperature…in addition your air conditioning unit doesn’t run as long and cycles less.
With the combination of the solar heat and changing the thermodynamic process of the refrigerant, Sedna Aire is able to reduce the required work of the compression operation of the compressor. This then lowers the required electrical consumption, reduces the running time of the entire system and maintains a more comfortable conditioned space.
Hate to watch that water flow down the drain while waiting for it to get hot? Many houses utilize circulation loops that cycle the water through the pipes, keeping hot water near the faucets. Those systems require a “return loop” pipe, typically a 1/2″ line from the farthest point of use. These return lines are frequently installed in new construction.
But, what about existing homes? Now there’s an answer: the Watts Premier Hot Water Re-circulating System.
This short article describes the operation of OPEN LOOP CIRCULATION TYPE DOMESTIC WATER-HEATERS.
Your Solar Water-Heater
Your home is equipped with an “open loop solar water heating system.” This system is composed of the collector panel, a large capacity storage tank and a DC circulation pump. The pump is powered by a photo-voltaic (PV) panel which is oriented the same as the collector array.
When the Sun is Shining…
The PV panel makes electricity that powers the pump. The pump draws the water out of the bottom of the storage tank, circulates it through the collector panels and returns it to the tank. The more direct the sunlight (striking the panels at right angles), the better the systems works.
In general, we attempt to orient the collector panels facing south at an angle of 18 degrees. Flat is OK.
When the Sun isn’t Shining…
The system doesn’t work. Electric elements in the storage tank will heat the water used at night or during cloudy hours. On foul weather days, the solar system may act as a pre-heater, raising the ambient temperature of the water a few degrees.
No Actions…
Are required on your part. When it is beneficial for water to circulate through the collectors, the pump will operate. When it isn’t, it won’t.
