6 FAQs about [Drain back solar system Tonga]

What are the operating modes of a solar drainback system?

Operating modes of the drainback technology are systematically evaluated: filling, operation, and draining. Hydraulics of drainback systems are described. Variety of components and associated requirements are presented. Although solar drainback systems have been used for a long time, they are still generating questions regarding smooth functioning.

What is a drain back module?

A simple gravity-driven process within the compact module Drain Back module ensures trouble free operation and system longevity for improved returns on investment in renewables for water heating in commercial buildings. Designed for single-row roof-mounted and console systems. Fully compatible with Adveco Flat Plate Solar Thermal Collectors

What is a drain back system?

At Adveco, we are proponents of systems that deploy drain back, which as the name implies drains the solar fluid from the collector to a reservoir when not in use, 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.

What is the draining process of a solar controller?

The draining process Once the solar controller turns off the pump (s) or in case of power failure, the draining process occurs automatically. It has a protective function for the DBS, and implies the draining of the HTF from the upper part of the hydraulics into the drainback volume.

What are the different types of drainback systems?

There are variations among the variations. The two dominant types today are the pressurized glycol system and the drainback system. One version of the drainback system has been in continuous operation since the late ‘70s.

What is the difference between a pressurized glycol system and a drain back system?

With no exchanger between the tank and collectors, the drain back system transfers 100% of the collector heat to the tank. It is the most durable. Glycols deteriorate over time producing acids that eat piping. Pressurized glycol systems have up to 30% shorter equipment life than drain back systems.
