  • Page 21: Chapter 3 Dimensioning

    Chapter 3 DIMENSIONING The dimensioning of the solar heating system starts initially from the identifi cation of its use: only the production of domestic hot water or the production of domestic hot water and integration of heating. An inspection of the building is of fundamental importance in order to identify the availability of an appropriate slope, with suitable surfaces and inclination.

  • Page 22: Production Of Just Domestic Hot Water

    Chapter 3 PRODUCTION OF JUST DOMESTIC HOT WATER The basic calculation for the dimensioning of the solar system for the production of domestic hot water starts from the identifi cation of the total consumption of the family in question. On the basis of habits, consumption of hot water can be low, medium or high. Table supplies the indicative values of daily consumption per person at the various comfort levels and for the household appliances prepared for direct use with hot water.

  • Page 24: Production Of Hot Water And Integration To Heating

    Chapter 3 PRODUCTION OF HOT WATER AND INTEGRATION TO HEATING The dimensioning of the solar system combined for the production of domestic hot water and integration with heating is much more complex with respect to that just for the production of hot water and must always be supported by a dedicated calculation and simulation program.

  • Page 25: Heating Swimming Pools

    Chapter 3 HEATING SWIMMING POOLS Heating a swimming pool using solar collectors is advantageous especially if combined with the combi system, as this allows effi cient disposal of the excess summer heat captured by the solar panels. The dimensioning of these systems, however, is not trivial due to the many factors that cause heat losses from the swimming pool.

  • Page 26: Series/Parallel Connection Layouts And Panel Arrays

    Chapter 4 SERIES/PARALLEL CONNECTION LAYOUTS AND PANEL ARRAYS The Extrafl ame solar kits are made up from two or more panels that must be connected to each other. There are three possible connections: in series, in parallel, and mixed in series – parallel. When the collectors are connected in series, they are passed by the same fl ow and the system fl ow rate that passes through each collector is the same.
  • Page 27 Chapter 4 fi gure 4.2 When more than 5 panels are to be installed, several arrays must be set up and connected to each other. In arrays connected in parallel using the Tichelmann system, the total length of the fl ow and return pipes must be the same.
  • Page 28 Chapter 4 However, with this system it is very diffi cult to obtain a uniform fl ow in the various panels and the total fl ow rate of the fl uid in the system is high, with consequent increase of head losses. It is therefore recommended to adopt a mixed series - parallel connection in a way to use a low fl ow circulation and at the same time uniformly distribute the fl ow rate into the various panels.

    Chapter 5 ASSEMBLY PHASE Remove a few tiles and look for safe anchorage points on the wooden beams or on the cement structure present under the tiles. Use the screws supplied or alternatively use solid plugs, which can be found for diff erent types of material (see fi gures 5.4-5.5).
  • Page 32 Chapter 5 Pay great attention not to ruin the gaskets on tightening and not to create twists in the collector copper pipe: it is recommended to tighten the joint manually and then slightly using the spanners as indicated in the fi gure. After having fl ushed the system, let a few drops of liquid leak out of the joints, which have not yet been completely tightened.
