Bubble Destruction
The Bubble Destruction Cycle
Sometimes we will want to remove the bubbles from the cavity space as quickly as possible. Instead of waiting for the bubbles to naturally dissipate we can remove most of the bubbles using a bubble destruction cycle. The control system will leave the pump turned off during the entire generating cycle. This cycle of operation of the bubble generator produces no new bubbles, since no soap liquid is supplied to the bubble screen. There is a small amount of liquid produced as the old bubbles are destroyed and this liquid will drain back to the soap reservoir.
The old bubbles move into the blower where they are destroyed and the air released passes out through the screen. The screen therefore remains too dry to produce bubbles and the lower backpressure of the dry screen will result in a higher air flow. The larger volume of air flow around the cavity space will move out all the old bubbles in the region of the roof and perhaps some from the wall cavity spaces as well. Any bubble residues still remaining in parts of the cavity will now be exposed to a large pocket of air that will have the affect of accelerating the dissipation of these bubbles as well. Thus persistent bubbles in the walls may also dissipate when the roof cavity space is cleared of bubbles.
Normally we would want to remove the bubbles in the morning as soon as the sun has reached a reasonable elevation. At this time a bubble destruction cycle is useful. Also, in the case where the bubbles have been used for shading and the sky clouds over it is useful to be able to clear most of the bubbles from the roof more quickly then if they were allowed to dissipate naturally. The natural dissipation of bubbles may be too slow if the soap liquid has additives that extend the life of the bubbles. A well configured flow-path in which the bubbles or air will channel smoothly is very important for the optimum function of the bubble destruction cycle.
In summary the proper function of bubble generation, regeneration and destruction give complete control over the properties of the Solaroof and together with the Liquid Solar process of climate control the bubble technology can produce ideal environments for growing plants and housing animals and providing healthy living, working and recreational spaces. The Solaroof processes are very dynamic and can be constantly monitored to provide automated response to the changes in the outside weather conditions. The system can capture solar thermal gain during the day, store it in the liquid thermal mass and then distribute this low temperature energy throughout the building envelope at night to eliminate the need for conventional heating of the interior space.
