Heating installations, i.e. those that provide a constant flow of heat, can be divided into two basic groups: providing comfort for people staying in the building and providing heat energy needed to carry out specific technological processes.
To design heating systems properly, knowledge of thermodynamics, fluid mechanics, as well as statics and flow-through equipment is essential. It is necessary to comply with all legal acts and standards necessary to calculate the heat demand important for the country in which the investment is located.
The design of the basic thermal energy transport system must always be preceded by calculations of the heat demand in the building, which will allow for the selection of an appropriate heat source (boiler, size of the municipal pipe connection, etc.) and the dimensioning of heat receivers (radiators, underfloor heating). The piping network connecting the source with the heat receivers is dimensioned because of the flows and limiting speeds of the medium in the pipeline and the limiting linear pressure drops. The system must then be fitted with a pump which, thanks to the differential pressure it generates, will provide sufficient flow at any point in the system. For this purpose, hydraulic calculations of the entire system must be carried out to select the pump and to balance the system hydraulically so that a sufficient amount of heat is supplied to all consumers as a result of the heat demand calculation. In practice, the results of the hydraulic calculations are achieved by means of the corresponding settings of the control valves at the branches of the system.
We have experience both in the design of heating systems that provide comfort for people and in the design of process heat systems.
We have already developed systems with typical heat consumers (e.g. radiators or underfloor heating coils) as well as with less common solutions (e.g. radiant heaters from warehouses and workshops, thermally activated ceilings). In projects we often use the possibilities offered by changeover systems, thanks to which the same installation provides heating in winter and cooling in summer.
