Vav systems are very cost effective from a chilled water and heating water pumping perspective.
Fan coil system advantages.
Fans axial blowing fan assisted coil heaters.
A key benefit of using a unitary based system such as the fan coil is that the energy for meeting the room heating and cooling loads is transferred to the conditioned space through pipework normally with heated or cooled water which requires significantly less space and transport energy than would be used to convey the same amount of heating or cooling by air.
As with any system it suits some buildings applications and climates better than others.
Because the unit transfers heat to the space using forced convection the coil heat transfer area required is reduced as compared to a chilled beam.
This simplified system has some clear advantages over a traditional central air conditioner but also has some disadvantages.
Ensuring the heat generated from the fan coil heating system can be adjusted in its direction ensuring that the heated air flow gets to the required areas and does it job.
When a fan coil unit is located above a t bar ceiling the noise it generates is difficult to control even with lined ductwork or silencers.
Fan coil unit systems.
The main source of noise in a fan coil is the small fan that circulates air through the coil and into the conditioned space.
High level of flexibility in terms of subdivision and rearrangement of.
Advantages of these fan coil heating units are.
A vrf air conditioning system is a particular type of heat pump air conditioning system in.
The system has all the benefits of a central water chilling and heating plant while retaining the ability to shut.
The system can accommodate up to 100 outside air capability.
The fan coil includes a coil that gets warm or cold depending on your thermostat setting and a fan to blow out the temperature changed air.
Figure 13 9 gives measured sound power levels at several rates of flow.
A major advantage of the fan coil unit system is that the delivery system piping versus duct systems requires less building space it requires a smaller or no central fan room and little duct space.
Condensate must be disposed of at each unit.
Fan coil system advantages.
Advantages of vav systems include the following points.
The air comes out of the fcu either cooler or hotter than before.
As a system variable refrigerant flow vrf has a lot to offer in terms of efficiency running costs flexibility in use and control.
The fan coil system requires more maintenance than all air systems and the maintenance work such as servicing filters is performed in occupied areas.
The advantages and benefits of fan coil units cheaper to procure and install than other central aircon systems because they commonly power small to medium sized spaces fan coil units are relatively cheaper compared to an air handling unit system and a larger central aircon system.
