Instal-therm HCR

The selection and design of heating elements

1. Selection of convection heaters:
   • thermal calculations according to EN 442-2
   • the method for selecting the size of the radiator - an authorial method
   • allowances taking into account housing, way of the power and location - guidelines from COBRTI Instal, information from producers
   • adjustment (correction ) flows - an authorial method.
2. Designing radiant heaters:
   • selection of temperature control - an authorial method
   • thermal calculations - standard EN 1264.

Calculations pipeline network

1. Hydraulic calculations - Darcy's and Colebrook's formulas.
2. Selection of the diameters - the criterion of R_max and v_max.
3. Balancing power - an authorial method.
4. Loss of heat of pipelines and insulation selection:
   • heat loss of pipelines - according to literature
   • selection of pipe insulation - recommendations EnEv (German) or WT2008 (Polish).

Instal-san TS

Installation of hot and cold water

1. Definition of calculation water flow:
   • Polish market: PN-92/B-01706
   • remaining markets: DIN 1988 or DIN 1988-300
   • in systems with hydrants - an authorial method that recognizes the maximum number of hydrants to include in the balance the user set.
2. Hydraulic calculations:
   • pressure decrease in the pipes: Linear resistance - Colebrook-White's formula , local resistance - Zeta according to catalogue data
   • minimum and maximum pressure ahead of outlet points , the selection pressure in the source - according to the standard from point 1
   • Calculation of load flow in the rings - an authorial method based on the Cross method.
3. Selection of pipes diameters:
   • according to the criterion of maximum speed
   • the diameter of the ring in addition according to DIN 1988-300.

Hot water circulation

1. Set of calculation circulating hot water flow:
   • an authorial "thermal" method based on analysis cooling of the water in individual circuits and maintaining a minimum velocity of circulation.
2. Hydraulic calculations of pipes:
   • pressure drops in pipelines: Linear resistance - Colebrook-White's formula, local resistance - Zeta according to catalogue data.
3. Selection of pipes diameters:
   • by criteria of maximum speed and maximum frictional resistance.
4. Balancing:
   • according to the general principles used balancing hydraulic circuits, as central heating circuits.
5. Heat loss pipelines and selection of insulation (also applies to the hot water network):
   • heat losses pipeline - according to literature
   • selection of pipe insulation - recommendations EnEv (German) or WT2008 (Polish).

Gravity Sewer
