FV KLIMA ASSEMBLY INSTRUCTIONS

1. USE OF SYSTEM FV KLIMA

Ceiling cooling/heating FV KLIMA is modern energetically economical system of a surface area cooling. It´s made in several contruction variations adapted to various ceiling constructions.

1.1. System CoolFLEX for metal soffits (full or acoustic)

System consists of thin cooling registers CoolFLEX, which are placed in metal soffit cassettes. Registers CoolFLEX are tailored according to project specifications. Cooling performance is up to 75 W/m2.

Assembly

  • Prepare metal carrying construction for ceiling metal soffits.
  • Install central distribution from pipe FV COOLING 16 x 2 mm and quick couplings into area of the soffit.
  • CoolFLEX registers are placed into the metal cassettes and connect to central distribution by use of quick couplings.
  • Run test of the sealing and test of regulation functionality.

1.2. System CoolFLEX for plasterboard soffits (full or acoustic)

SSystem consists of then cooling registers CoolFLEX, which are placed on plasterboard panels and it offers simple and safe mounting. For securing of maximal performance there are used plasterboard panels with increased thermal conductibility (including graphite). For docking the system uses standard metal contruction designed for plasterboard ceilings, using CD and UD metal profiles. Registers CoolFLEX are tailored according to project specifications. Cooling performance is up to 70W/m2.

Assembly

  • Prepare metal carrying construction for PBD ceilings. Spacing of mounting sections is 500 mm for full and 333 mm for acoustic soffits.
  • Install central distribution from pipe FV COOLING 16 x 2 mm and quick couplings into area of the soffit.
  • Stick registers CoolFLEX to mounting sections and connect those to central distribution by use of quick couplings.
  • Run test of the sealing and test of regulation functionality.
  • Close ceiling with plasterboard panels with thermal conductibility according to project documentation.

1.3. Active plasterboard panels CoolPLATE

Cooling pipes are placed in plasterboard grooves. Individual active cooling panels CoolPLATE are tailored according to project specification. Active plasterboard panels are installed to standard metal contruction designed for lowered ceilings, using CD and UD profiles. Cooling performance is u to 60 W/m2.

Assembly

  • Prepare metal carrying contruction for plasterboard ceilings. Spacing of mouting sections is 333 mm.
  • Install central distrubution from pipe FV COOLING 16 x 2 mm and quick couplings into area of the soffit.
  • Fasten active plasterboard panels CoolPLATE to mouting sections and connect those to central distribution by use of quick couplings.
  • Run test of the sealing and test of regulation functionality.

1.4. Cooling system in plastering CoolGRID

CoolGRID cooling registers are located in the plaster ceiling. They are used in combination with core or gypsum plaster in a thickness of 10 - 20 mm. CoolGRID cooling registers are supplied pre-fabricated or directly mouted at workplace. The cooling performance is up to 70 W/m2 depending on the pitch and used plaster mixtures.

System CoolGRID assembly procedure

  • Ceiling must comply to base flatness conditions pursuant to ČSN EN 13914-2 (5mm/2m). Base ceiling concrete must be hard and dry, it is necessary to remove any dirts and flatten jogs.
  • In the rooms where the ceiling cooling system is to be installed there should be processed base in line with technological regulations of plastering substance supplier.
  • Install central distribution from pipe FV COOLING 16 x 2 mm and quick couplings.
  • Place docking grooves for pipe ø 8 x 1 mm in required spacing to the area od ceiling. The best way to place grooves is to fasten those with dowel ø 5 mm or other appropriate way.
  • Place pipe FV COOLING 8 x 1 mm to the grooves and connect that to central distribution with use of quick couplings.
  • Run test of the sealing and test of regulation functionality.

Plastering the system CoolGRID

  • For plastering of the ceiling we recommend to use appropriate gypsum plaster or core plaster substance with thermal conductibility relevant to the project. Application is to be regulated by substance suppliers notes.
  • Minimal thickness of the plastering is 20 mm.
  • Sizes of dilatation units are to be regulated by used plastering substance notes.
  • Within plastering there must be suitable pressure it the system and it is necassary to perform checkouts of the pressure in system.

2. Basic recommendations for design and installation FV KLIMA system

  • To prevent condesate appearance, ceiling must be laid out in such a way, so feed water temperaturewould be always above condensate point temperature.
  • required height of the soffit construction within plasterboard and compartment ceilings is 6 - 20 cm.
  • In case of the system cooling plastering, it is recommended total thickness of plastering 2 cm.
  • Optimal length of circuit with pipe ø 8 x 1 mm is 20 - 40 m.
  • Optimal active cooling area size for one sub-circuit of distributing pipe ø 16 x 2 mm is 10 - 15 m2.
  • Up to 15 cooling sub-circuits can be connected per one manifold.
  • Each sub-circuit must be equipped with regulating valve with actuator.
  • Condensation point receptor must be placed in each room on the feed duct.
  • It is recommended to provide air ventilation with modified air.
  • If using heating system it is recommended to use insulant material of thickness 3 - 5 cm above cooling registers.
  • If using ceiling system for heating is temperature of heating water limited to 45°C.
  • System can be feeded by drinkable water without mechanical dirts.
  • Dilatation of cooling/heating ceilings must be designed and applied according to technical layouts and recommendations of plastering substances and plasterboard panels producers.

3. Commissioning

After assembly and checkout of whole system there is feeding of circuits with clear water according to following procedure:

  • All circuits on manifold are closed with use of manual caps and flow meters rotation.
  • Pressure water is supplied to feeding manifold valve and hosepipe is placed to emptying collector valve and conducted away to sewer.
  • First circuit is opened, water is allowed to flow and once clear air-free stream of water flows the circuit is closed by both valve and flow meter.
  • Another circuit is opened then and so step-by-step is feeded the rest of circuits afterwards both distributer units are deaerated having closed valves and flow meters.
  • All circuits are opened and sealing test is run according to following procedure system is pressured to 6 bar, pressure is maintained during 10 minutes and then quickly released.
  • System is pressured to 2 bar, pressure is maintained during 10 minutes and then quickly released.
  • System is pressured to 4 bar. Pressure mustn´t be decreased under 3,4 bar during 30 minutes and during another 2 hours under 3,2 bar.
  • During test there mustn´t be leakages, test records shall be done.
  • Circuit pumping device is launched and projected flow in all sub-circuits is set by rotating of flow meters.
  • Functional test of regulation is done and the system is propared for use.

4. Fittings assembly process

Fittings assembly is made according to following working procedure. Along whole time of handling with fittings it is necessary to take precise care about cleanliness of the fitting and pipe as well, predominantly of their sealing parts.

Pipe is cut by pliers vertically to the duct axis. To prevent pipe flattening it is recommended to rotate pipe in the pliers.
Internal edge of pipe is slightly splayed by manual reamer to depth approx. 1 mm.
Reinforcing case is fully inserted into pipe.
Ending of pipe is covered by FV silicone paste in range of 15 mm.
Fitting is fully slip over pipe. Pipe 16 is slip over for 24 mm, pipe 8 for 20 mm.
Marks printed on the pipe are designed for orientation.
