Fan Coil Heating and Cooling System
Monday Nov 14th, 2016Share
The Majority of newer condos has fan coil heating and cooling system. Sometimes these systems are described as Forced Air or Heat Pumps. There is, however, a difference.
Principle of System Operation:
The Air is circulated and is taken in from the intake vent at the bottom and is blown out from the top vent either warm air in the winter or cold air in the summer. It is important that the lower vent is not blocked by furniture as it will not work properly and the obstruction can burn out the fan motor.
The system can be a 2 or 4 pipe system extending throughout out the building.
The two pipe system has a supply and return pipe filled with either hot or cold water depending on the season. Air is blown over the pipes ti heat or cool the unit.
In a 4 pipe system, one pair of pipes carry the hot water and the other pair carries the cold water.
Advantages of a 4 Pipe System:
In a 4 pipe system, each suite can control individually whether the air is heated or cooled. In a 2 pipe system, the controls are central and depending on the unit exposure, for example, North or South, the Suite Owner may find themselves too warm or cold in a short period during the seasonal changeover.
There should be an annual preventive maintenance performed on the system, such as changing the filter and checking the unit fan located behind the lower panel to ensure it is functioning properly. This must be performed by a qualified technician
In many buildings, the maintenance is not included in the common elements and is the responsibility of the unit owner.
When purchasing a condo, the prudent thing to do is to check with the property manager and determine the exact responsibilities of the Suite owner and the Condominium Corporation.
