Office space

In service-sector projects, unit ventilators and chilled beams make up the majority of heating and air-conditioning generators. Air conditioning is the major factor to take into account when designing the overall installation. Water delivery is a minor concern, because the networks ensure basic cold-water delivery, with some local production of hot water within each water-system bloc.

Generator parts

In construction intended for use as office space, the boiler is generally below-ground. Chillers for cold-water production or high-power heat pumps, including absorption cycle heat pumps if any, are placed at roof level in a special technical area. They serve emitters and air treatment stations. 

Distribution may be done in several ways for office buildings. Here is a two-pipe ceiling system, two-wire, with change-over. Alternative configurations may be used (two-pipe change-over, four-pipe, etc.)

Interfaces

In office space, the interface is generally installed by simply tapping the riser columns at each floor to supply the horizontal loops and distribution branches. There is no part specifically designed for this function.

Unit ventilators

Water

  • Hot-water production may be individualised per water-system bloc and by floor. But a more powerful generator may be able to supply a floor and the one above simultaneously. Distribution may be achieved with COMAP BetaPEX pipe (Ø 12) and PexPress press-fittings.

Control and parts for emitters

Unit ventilators 

  • Control and balancing of emitters may be performed with Ballorex pressure-independent control valves (PICV), governed with electrothermal heads (actumod model or actu on/off model, depending on the type of control desired). A centralised technical management (CTM) system controls the overall installation.

Water treatment and quality

In an office building, water quality is essential for networks to last, but also for the occupants who use and drink the water.

To protect equipment, installing a COMAP sludge collection unit completes the initial outfitting with a large-capacity retention device on the primary circuit. It guarantees that impurities from the looped heating circuit do not recirculate. The risks of total or partial blockage and of premature corrosion due to differential airing are limited.

Depending on water hardness, a large-capacity COMAP water softener may be installed to prevent malfunction linked to calcium deposits.
