Following list the various types of Residential-Office Air-Conditioners:

 

Room Air-Conditioner

Room air-conditioner usually cool just one area or one room .  The most common one is called the Window-Unit air-conditioner.   Owners oWindow Unit Air-Conditionerf older and rental HDB flats usually install this type of room air-conditioner.  The compressor, evaporator coils and condenser coils are all rolled into one compact unit which is usually installed on the bottom panel of the room’s window.  A strong steel bracket is used hold the unit.

Ductless, mini-split air-conditioner systems (commonly also known as Multi-Split Systems), are similar to the central air-conditioner system except they are smaller in scale in the machinery and the size of the supply ‘duct’.

 

The system comprises of:

  • An outdoor compressor or condenser
  • An indoor air-handling unit or fan coil unit which is commonly installed Wall-Mounted

However, because Multi-Split Systems are “ductless,” they are often used in homes and smaller offices with non-ducted systems. Instead, a setup is present to connect the outdoor unit with the indoor unit.  This consisting of the electrical wires, tubings for the aircon gas and suction, and the condensate drain..

Most flats and apartments nowadays install the Multi-Split System to cool several rooms with just one outdoor compressor or condenser usually installed in the AC ledge.

 

 

What is “System-X”?

When selecting the Type of Air-Conditioner System,  we  often hear of “System-2” all the way to “System-5” air-conditioners.  What exactly does this refers to?   It is the ratio of 1 compressor to the number of fan coil unit it powers.   Please refer to the following table:

 

  • System-1: One outdoor unit powers 1 fan coil units (1 room
  • System-2: One outdoor unit powers 2 fan coil units (2 rooms)
  • System-3: One outdoor unit powers 3 fan coil units (3 rooms)
  • System-4: One outdoor unit powers 4 fan coil units (4 rooms)
