How does air conditioning work?

Air conditioning essentially cleans and dehumidifies (removes excess moisture) and keeps a set temperature constant. Each conditioning unit has a compressor which circulates a liquid refrigerant.

The compressor moves the refrigerant from an evaporator, through a condenser and expansion valve, back to the evaporator. The evaporator is in front of a fan that pulls hot, humid air out of a room. The refrigerant makes the hot air’s moisture condense into drops of water, removing the heat from the air. Once the water is removed, the cool air is sent back into the room.

How are air conditioning heating/cooling units controlled?

Some systems are controlled manually, others by infra-red remote control. Split systems, for example, have an infra-red remote control with functions to control temperature settings, timers and fan speeds and heating/cooling/fan modes. Ducted air conditioning systems are controlled generally through a centrally located wall mounted controller. This unit controls temperature settings, fan speeds, modes and timer functions.

What is the difference between a room air conditioner and a split system?

A room conditioner is a traditional form of cooling where the compressor and fan are together in one box. The units are generally installed into a window or wall. A split system comprises of two units – the outdoor condenser and compressor, and the indoor unit which houses the evaporator fan. These units are connected by refrigeration pipes. The design of a split system allows the unit to be quiet in operation, and generally more efficient on electricity use.

What are the benefits of a ducted system over a split system?

A ducted system is designed to cool more than one room within your home. The indoor fan coil unit is situated manually in the ceiling space and is connected to the outdoor condensing unit. Individual outlets are situated in each room with the cooling unit controlled by a central controller. Unlike the ducted system, the split system is primarily designed to cool only one room.

If you want to cool an entire house then a ducted system is the best option. Ducted systems are less obtrusive than wall mounted split systems and have the ability to efficiently cool large areas.

What is zoning in a ducted system?

Zoning allows temperatures to be varied in certain areas of a house. This is done through the use of zone controls in the ductwork in the ceiling space. For example, a two-storey house may have an upstairs and downstairs zone, commonly called a day/night zone. A larger house may have four or five zones.

Which is the best ducted heating/cooling system for me?

The size and design of a ducted cooling and/or heating system depend on a range of factors:

  • Your home’s floor plan: How many levels are there? What are the dimensions of the rooms (including ceiling height)? Which direction do the rooms face?
  • The size, position and orientation of windows and doors.
  • The type of construction (for example, weatherboard or full brick).
  • The level of insulation.
  • The number of people living in your home.
  • The main use of the area (for example, sleeping, living, cooking).
  • The ceiling cavity space – slimline systems are available for homes with small ceiling spaces.
  • Outdoor spaces – The outdoor compressor unit(s) should be installed somewhere where noise won’t be an issue (for you or your neighbours).
  • Large systems may require a three-phase power supply.

Ambience Air can design or recommend a system for your individual situation.

What is reverse cycle air con?

Reverse cycle refers to a system that can be switched to either heating or cooling depending on environmental conditions. Most modern units have a reverse cycle function.

Reverse cycle advantages:

  • Economical form of heating
  • Heating and cooling from one main unit
  • Unit stays cool to the touch, even when heating
  • No exposed metal elements or flame
  • They dehumidify and filter the air

What’s an Inverter?

A new innovation, an inverter is quieter during operation and more energy efficient than a conventional unit. The finely tuned operation of the inverter allows quick cooling or heating and less temperature variations in a room. It uses a variable speed compressor.

Inverter technology advantages:

  • Significant energy savings
  • Quiet operation
  • Quickly reaches desired temperature, with less variations
