Drainback solar thermal systems: A review
A drainback system corresponds to a "solar thermal system in which, as part of the normal working cycle, the heat transfer fluid is drained from the solar collector into a storage device when the pump is turned off, and refills the collector when the pump is turned on again" (ISO, 1999). This unique attribute to empty the collectors and to

Overview of Building Integrated Photovoltaic (BIPV) Systems
building integrated photovoltaics (BIPV) system is an attractive application of solar energy. In fact the annual rate of PV utilization grew worldwide from 20% in 1994 to 40% in 2000 (Figure 1)[1]. In designing an AC grid-connected BIPV system for Hong Kong, engineers have to consider a lot of variable factors such as local climate

Drain-Back-System – Wikipedia
Ein Drain-Back-System (englisch drainback solar water-heating system [1]) ist ein bestimmter Typ einer thermischen Solaranlage i dieser Bauart gibt es keinen herkömmlichen Stagnationszustand der Solaranlage.Die englische Bezeichnung Drain-Back bedeutet in etwa so viel wie Rückfluss, [2] hierbei wird eine automatische Entleerung der Kollektoren bei
The drainback system
The drainback system. There are 2 basic types of solar thermal system - Drainback systems and pressurised solar systems. If you are familiar with heating systems, a good way of comparing them is a drain back system is comparable to an open vent system, and a pressurised system is comparable to a sealed system. Drainback systems
Solar Thermal Drain Back
Drain back systems for commercial solar thermal prevent overheating in collectors to extend system life-span and maximise spend on renewables. allowing for a system to be safely off. A drain back vessel located in the plant room is one option, that will also allow for pipework fluid, but will require greater head pumps.
