Fan coil units: What are they? https://www.topenergy.ro
Fan coil units are special installations for air conditioning rooms, which ensure silent and durable operation, with low energy consumption, both in summer and in winter.
For heating and cooling spaces, fan convectors use water as a heating agent. Thanks to the cooling and heating functions, the fan coil units ensure a high level of comfort, offering the rooms both economic and aesthetic advantages.
Fan coil units can be installed:
- on the floor
-on the wall
- on the ceiling
Fan convectors can be used together with wood chip/biomass heating plants, with heat pumps or apartment plants.
For heating and cooling spaces, they use water as a thermal agent. Thanks to the cooling and heating functions, they ensure a high level of comfort. It offers the rooms both economic and aesthetic advantages.
In a simplistic way - the fan convector can be assimilated to a radiator to which a fan has been attached. It is placed in a heating circuit and has the great advantage that it achieves the air conditioning of the room much faster, through that current of air set in motion by the fan.
IDepending on the season, hot or cold heating agent can circulate through the fan convector.
In the summer, when it gets cold, it must be provided with a drain for condensation, similar to conventional air conditioners.
As for costs - they are higher, but they are amortized faster if used in combination in winter/summer.
How does it work?
It is a system used a lot in the past, especially in thermosyphon natural circulation systems. These systems did not have a pump and the diameter of the pipes were large, 4-6 inches with an expensive investment. Series monopipe circuits are still used nowadays, together with circulation pumps.
With this system, the thermal agent passes through each radiator and returns to the heating circuit at a lower temperature. After passing through the first radiator, the thermal agent with the lower temperature enters the next radiator, cools down and then enters even colder in the next one until the last radiator connected in series.
This progressive decrease of the thermal agent along the heating circuit is a problem of the mono-pipe system and must be taken into account in the design. It is necessary that the dimensions of the radiators be progressively increased, especially those farthest from the boiler. Also, due to the insertion of the radiators, the hydraulic load losses are somewhat higher, thus leading to a stricter limitation of the length of the circuit.
