2.6 Audits and essential parameters for the sizing
To design appropriate and targeted to the creation of the solar system with only benefit for the end user must
carry out some important preliminary checks by the collection of data essential for proper sizing:
DESIGN LOCATION
The place where it is installed the system provides valuable indications as to size, such as radiation monthly
average, monthly average outside temperature, average monthly temperature tap water, value of average
relative humidity, monthly average speed of the wind.
AVERAGE CONSUMPTION
Consider the daily needs of the family. Consider a hot water consumption approximately 45 °C from 50 to 70
l/day per person (usually) or at least an average hot water consumption per person = 40 l/day for Ireland
market. Identify any requests for simultaneous use hot water. Check the period of use of the plant (seasonal
or months of use).
DESIGN SYSTEM
heating domestic hot water : identify the required consumption and water temperature from these values
you can decide cylinder size.
Generally, for solar, the cylinder should be sized to accommodate approx 1-2 days usage or should be sized
to accommodate twice the expected daily consumption for the household or dwelling.
heating domestic hot water:
hotel, gym, etc. -as reported previously indicating regarding the mode of
consumption and period of use. For these types of system, however, is always necessary to develop ad hoc
designers or technical staff by Kloben.
Space Heating: Radiant only - indicate areas to be heated, spacing and type of installation of the pipe
insulation.
Swimming Pool: specify whether indoor or outdoor use any night of coverage, the required temperature,
period of use.
FEATURES OF THE STRUCTURE OF INSTALLATION
Surfaces designed to accommodate the field of solar collectors are an important design constraint to
consider, because the positioning of the solar collector is to influence the uptake’s efficiency of solar
radiation. The things to check are: the possibility of mounting on roof or above roof, the availability of
groundwater roof facing south or alternatively oriented to the east and west slope of the roof pitch, the
presence of other systems, etc..
By current rule UNI 9182, are deduced the data regarding the capacities and needs hot water depending on
the activity in question and the individual dwellings.
Above information refers to a preliminary design and it is related to residential areas with a standard type of
consumption of an average family. However, for correct sizing of all parts of the plan must be taken into
account, in addition to preliminary tests, also all the peculiarities of dwellings and then proceed with the
definition of energy requirements, mode of delivery (flow, temperature, time of request) and finally correct
sizing for all components based on power and performances of the various components of exchange: solar
surface, solar heat exchangers, storage, etc..
For Northern Ireland market: Solar hot water systems as whole for any dwelling falls under building
regulations Part L 2008,then it is obligatory to produce a certain amount of energy using renewable
technologies: this is usually 50-60% of the annual hot water requirement, but this can vary depending on
economics and hot water requirements.
For this reason and for an accurate sizing, please refer to the technical staff by Kloben.
ATTENTION If you choice an installation of solar system for one already in operation, it is absolutely
essential have the detailed diagram of the existing thermal power plant, without which it will be
possible to provide no guarantee of performance.
