March 2014 Edition

Integrated systems Baxi has always been active in the development of solutions which ensure the maximum environmental respect. Baxi is also aware that next futureâ&#x20AC;&#x2122;s heating solutions are based on the integration of boilers and systems working with renewable energies.

Following this philosophy, Baxi has developed the integrated solar system combining the excellent technology of Baxi boilers with a complete range of solar collectors and cylinders for forced and natural draft installations. A concept of intelligent comfort with low pollutant emissions (ecological comfort) and high energy efficiency.

Principles of solar Energy Smart comfort: the integrated Baxi solar system Sun energy: an opportunity to be exploited Every object directly exposed to the sun absorb heat and increase its temperature. As a consequence of the chemical reactions that take place in the mass of the sun, a constant stream of energy is produced as electromagnetical radiation. We define the “solar constant” as the amount of incoming solar electromagnetic radiation per unit area, measured on the outer surface of Earth's atmosphere in a plane perpendicular to the rays. The solar constant includes all types of solar radiation (infrared rays, UV rays, etc.), not just the visible light. It is measured to be roughly 1353 watts per square meter (W/m²), though this fluctuates by about 6.9% during a year (from 1,412 W/m² in early January to 1,321 W/m² in early July) due to the Earth's varying distance from the Sun, and typically by much less than one part per thousand from day to day. The approximate average value cited, 1353 W/m², is equivalent to 1.96 calories per minute per square centimeter, or 1.96 langleys (Ly) per minute.

As above stated, the Earth receives a total amount of radiation determined by its cross section but, as it rotates, this energy is distributed across the entire surface area. Moreover, at any given moment, the amount of solar radiation received at a certain location on the Earth's surface depends on the state of the atmosphere and the location's latitude. According to what described so far, we can state that many countries of the European Continent are well located in order to successfully exploit Sun energy.

Solar Info Tech Receiving system It’s possible to get electricity and heat from solar energy: a thermal solar system converts the solar radiation into heated water to be used for home consumption. The thermal solar collectors are the devices able to perform this conversion.

The inclination of solar collectors The inclination of solar collectors is the angle between the plane of their surface and the horizontal surface they rest on. To optimize collectors efficiency, the angle between collectors surface and incident rays should be 90°. If collectors rest on a pitched roof it’s advisable to keep the same inclination of the roof. On the other hand, if they rest on a flat roof the following indications should be considered when deciding the collector inclination: • Summer 20 – 40° • Winter 50 – 65° • Middle seasons 40 – 60°

Inclination angle between the collectors and the horizontal plate

SUD

Orientation angle of the collectors toward South

It is easy to determine the correlation among collectors inclination, orientation and solar radiation in the in the diagram below reported. Thus, itâ&#x20AC;&#x2122;s possible to make a rough calculation of the collector efficiency according to different inclination values.

Design limit snow load on the ground = 2.3kN/m² SB20+V SB20+O Design limit snow load on the ground = 1.9kN/m² SB25+V SB25+O NOTE: This limit will be reduced for installations where abutments create additional risks of drifting or falling snow. In high snow load areas (greater than 1kN/m²) it is recommended that a snow fence is fitted at maximum distance of 0.5m above the collector. The maximum wind load to be borne by the mounting structure depends on the height and geographical area of the site among other factors This structure must be installed in accordance with the provisions of the EN1991 standard. 21

Solar Info Tech

Accessories for forced draft installation Controllers The perfect functioning of the system can be obtained through the optimization of the flows of each circuit, reaching the right room temperature as well as measuring the spoiled energy. This goal can be reached through simple and compact controllers, which receive signals from various elements and allow to set the control temperature, the timings for switching on auxiliary boilers, etc. The controllers transform the reading of the temperature into an electric signal that switch on/off a specific process. The controller allows the fluid to get into circulation only with a real solar energy power support; it measures the temperature out of the collector and in the bottom of the tank through sensors. The differential thermostat compares both temperatures and in case the temperature is higher than the set limit, the circulating pump starts working. Apart from what explained above, the controller can be adopted in different points and for many uses inside these types of installation.

“Eco” controller (cod. LSC71000002) The differential temperature controller “Eco” used in the Baxi integrated solar system, is characterized by the easiness of use, thanks to a simple display, with only 4 buttons, of the system’s working.

Features: • • • • • • • •

Intuitive operation with an easy menu using symbols Digital temperature regulation 2 sensors that can be linked Control device of the solar circulating pump (n° of turns or ON/OFF) Solar tank cooling function Protection of the collector against over temperatures Display of the anomalies and memory of all the set parameters set also in case of long electrical power interruption Sensor included: 1 for tank – 1 for collector
