Description

This compact, vacuum tube solar heater is capable of heating water to temperatures of consumer health safely through its antilegionella (antilegionnaires disease) system. The objective of the model is to achieve superior performance and durability.

 

The system used in this model is the natural circulation of fluid (water/glycol) between the collector and the accumulator/heat exchanger. Vacuum tubes are filled with fluid which is the natural heat transmitter. Heat is radiated, captured and transmitted to the inner tube and naturally heat rises to the top, inside the accumulator. When the fluid temperature inside the vacuum tubes increase, temperature rises in the accumulator and simultaneously fluid of lower temperatures drop towards the end of the vacuum tubes, causing a natural circulation of heat within the system.

 

Thanks to the concept of the vacuum tube, heat loss is minimized to practicaly zero The tubes are able to capture the diffused light on a cloudy day, leading to heat the water to usable levels and store this water in the reservoir through the thermosyphon effect.

 

Through this antilegionella system, the water stored in the deposit, never mixes with the sanitary hot water. This is achieved through a copper coil that acts as a heat exchanger by circulating water at the pressure of the network, heating itself instantaneously. This system can produce more hot water than traditional systems, since there is no volume limitation of the accumulator.

 

 

One can say that this solar thermal system consists of a series of small individual boilers (each tube), so that repairs and replacements can be performed easily and inexpensively, simply by replacing the defective tube. It has some exceptional qualities to adverse weather conditions, withstanding impacts of hail of 25 mm. and winds up to 120 Km/h.

 

 

Use of this solar heater is especially suitable for houses, so that the installation of the system can perform a simple way to produce hot water at a constant temperature. To optimize the system, one must use a mixing valve rated at a temperature of consumption. With the antilegionella system, not only does this produce hot water safely, but you can get more quantity than traditional systems because there is no limitation on the volume.

 

To ensure optimum performance, the unit has a mechanism that makes filling the tank automatically easy to ensure the optimal level of storage, as well as a lung to relieve the expansion of it.

 

Applied Technologies

Vacuum tube

 

It consists of 2 concentric tubes of borosilicate glass, these tubes exist between a pressure below 0,001 atmospheres, and there is also an absorbing layer on the inner tube that captures the sun's rays and provides a great amount of heat.

 

Thermosyphon

 

Its operation is explained by natural convection currents of fluids, where the hot parts tend to rise by density variations experienced when heated in a cool part of it and into another. This phenomenon is also known as a natural circulation system.
