Solar collector - difficult ?? Nesmīdini me :) | It says Andžs ...
With this article I would like to izdzenāt myth that solar collectors catering food warmers is something impossible and that the fitting of their existing heating systems, first of all, it is not possible and, second, terribly expensive. It is not. Well, maybe it :) propose to self-directed scheme, which is valid for summer conditions where laziness is only stoke the boiler hot water due or worse, be heated with electricity.
Now let's top image. If an element is not known to have cab on the right side under the name "Legend". I have drawn a boiler with 2 "snakes" - one boiler, the second collector. So pump forces water through the collector to 2 residential buildings division, where sunlight warms the liquid. Supreme system in place (above the collector) should preferably be placed vent. Next, the liquid circulates back through two divisions and re-enters the boiler, which cools and flows back to the collector. As can be seen, there is no glycol or automatics, a maximum of a few elements (a couple of ball valves, not a thermometer or pressure gauge (which probably is not particularly brag)), only the elements of the system investigated. The tube appears to be DN20, galvanized steel (to nerūsētu), catering food warmers copper or other heat-resistant material. For maximum effect of the money spent, preferably insulate pipes, because it will pay off.
Next, turn to pump pump group. The pump has been charged before the manifold, where it will not as hot as the circumstances behind the manifold. The pump can be removed from the system by closing the front and back of the ball valves and draining a minimal amount of fluid from the system. Why pump imposed parallel to one another tube, which I shall explain later. Meanwhile, you can guess.
Next comes the security group. It consists of a safety valve of the expansion tank, the breather valve. Needless to not remind that the same air vent at the highest point is located catering food warmers so that the air bubbles that can occur in the system interferes with the system work. And they are always so fondly and predictable that always catering food warmers rises. Expansion vessel, because the system is shut down. Its aim is to equalize the pressure fluctuations in the system. Above is the mark of the safety valve 3 bars. Until these 3 bar pressure in the system is still not compress the safety valve built into the spring. When the pressure reaches 3 bar pressure slightly catering food warmers leaned, as a result of the valve izšļāksies liquid. It šļāksies until the pressure in the system drops below a pusbāru 3 bars. Another add that occasionally desirable to turn the safety valve, because, first of all, check if it would work, and secondly, available under the accumulated air.
Next, the system filling and emptying. The boiler from the left side of both sides of the ball valve DN20 are two connections. When filling an empty system, this valve DN20 turned away, replenishment of the water supply valve and emptying valve opens. Stream flows through the pumps, the tube (te its meaning) to the collector and back to the boiler and through the emptying tube. It can be seen that the system is filled, catering food warmers close the water replenishment and emptying valves. Opens DN20 valve. Water bubbles rising catering food warmers to the top. Insidious is still hidden somewhere in the system. They can be fully izdzenāt by turning on the circulation pump and open the water supply valve topping to fill vacancies. Also recommended to turn the safety valve (at least at the pictures it can be seen), chances are that there will be a little accumulated catering food warmers in the air. In this manner, the system performs refilling. Emptying. It is mandatory for winter catering food warmers conditions catering food warmers when the pipe freezes and is torn. This, of course, is a trifle to the fact that most certainly tear the dear solar collector. Beside the expansion tank valve is titled winter emptying. If this here space in which the boiler, pump and other systems armature (below the first covering panel) is heated in the winter, it is ideal. Opening the winter emptying valve, all the water above that flows out through the valve (also from the red tube -> boiler snake -> and the pump through the parallel tube). The water will be warm, the system safe. And then, on the summer side will again be refilled with water. When you open the water replenishment valve, air vent above the roof Rukši alone, but be patient - the system capacity is small.
More than a couple of details. To neatgaiņātu you from wanting to install solar collectors, offering a complex formula simplified. 18L expansion tank will be useful in virtually all cases, if installed one solar panel, catering food warmers as well as the system is so low-tech how to paint. The pressure to be the same as the heating - 1.5 bar. So the time in Manisa, or need to be changed or not. Expansion tank pressure settings performed as follows. Early on bought catering food warmers a bicycle pump and pressure gauge. When you first purchase a season expansion vessel, back pressure will not change. After the first winter, spring or summer (when'd be ready to fill the collector) iepumpē expansion catering food warmers vessel air (never mind that the opposite is not water) only Do not exaggerate because you can p
