Hotels

The hotel sector brings together the requirements of multi-family housing and commercial space. Industrialisation, prefabrication, time savings and an energy-efficiency guarantee are all the more important because projects are often replicated identically by large companies, whose projects have very standardised specifications.

In the hotel industry, the preferred heating and air conditioning solutions use two pipes: suspended-ceiling unit ventilators (installed in soffit) or ductable systems. Current practice includes installation of individual thermometers in each guest room.
Four-pipe systems may also be installed to meet occupants' comfort expectations with more precision.

Water systems are generally high-flow (increased coincidence factor) to reduce waiting times and guarantee stable water temperatures. For other points in the system, the logic is often the same as for office and commercial space.

Generator parts

The boiler is placed in a dedicated technical space, located below-ground or at roof level.
The cold group exterior unit is usually placed at roof level, always in a designated technical area.

  • Hot water generation is generally coupled with the heating device. To guarantee that occupants always have constant access to hot water (especially during consumption peaks), a heater connected to a high-capacity storage tank is installed.

Primary networks

In a hotel, the primary network generally consists of several columns situated between two guest rooms. These columns perform distribution for the water, heating and air conditioning systems. They are accessible through areas between rooms.

Heating and air conditioning

Sanitary

  • Centralised cold and hot water columns may be built with COMAP MultiSkin pipe (Ø 32 to 63, pre-insulated for hot water circuits) and SkinPress press-fittings for multilayer pipe.
    The expected comfort level and sanitary requirements make looping necessary on hot-water networks. This may be achieved with pre-insulated COMAP MultiSkin pipe or pre-sheathed and insulated COMAP BetaPex pipe (Ø 20), with the correct fittings for the material chosen: press fittings for SkinPress multilayer pipe or PexPress press-fittings.Hot-water columns and loops must be insulated.

Interfaces

In hotels, as 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.

Secondary networks

In the hotel sector, secondary heating and air-conditioning networks are usually placed in the ceiling, with ducted piping. Appearance may be an important criterion for secondary water networks, depending on whether or not they are encased.

Regulation and parts for emitters

In the hotel sector, this installation point is generally placed in the ceiling, ducted or an in-wall unit ventilator.

  • Control and balancing of emitters may be performed with Ballorex Dynamic pressure-independent control valves (PICV), governed with electrothermal heads (actumod 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 a hotel environment, water quality is part of the comfort offered to guests, particularly for bathing. It is also crucial so that systems are long-lasting.

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. It also supplies high-quality water for occupants, pleasant to use and consume.
