What type of air conditioning is best for you?

Office air conditioning

When having air conditioning installed in a office it is worth buying a quality unit. Cheaper units lack control features that more commercial air conditioning systems have as standard. For example a 24Hr timer so when your office is not occupied, the air conditioning is not running costing you money. Quality systems have superior mode settings for heat / cool / fan / dehumidify / auto. Cheap systems lack automatic feature which lets you set the temperature and the unit will change between heat and cool automatically. Most commercial air conditioning systems have 3 years warranty and because they have a higher coefficient they usually have a ECA listing (air conditioning heatpumps only).

Bedroom air conditioning

If you are thinking about buying air conditioning for your bedroom it is advised to purchase a unit with a low noise Db on the indoor unit. Whisper quiet is considered to be 25 Db and a quiet office 40 Db. This is a important factor to take into account. Some manufactures have made great efforts to reduce noise on the indoor air conditioning unit.
  
Home air conditioning units

Air conditioning for home use can vary in price considerably depending on the type of unit you decide on. If you are looking to have a totally concealed air conditioning system for a larger area or entire floor area, then you will require a ducted system or cassette air conditioning unit. These units require a void of around 300mm above the ceiling. They can be more costly to buy but provide an unobtrusive way of conditioning any environment. For spot cooling an area such as a bedroom or lounge, wall mount units work out to be a effective and cost effective way. As in the bedroom advice, noise is worth taking into account.

Inverter Energy efficient air conditioning heat pumps

The latest air conditioning system's are some of the most efficient ways to heat or cool an area. It is worth taking into account the C.O.P of a unit. The higher it is the more efficient it is. If a unit has a C.O.P of 3.8, then this mean that it will achieve 3.8kW output from a input of only 1kW. This reduces electricity usage.

Fixed speed or Inverter air conditioning?

Inverter air conditioners are not new to the air conditioning industry having been around for +10 years now. The technology has now been miniaturised and manufacturing costs have fallen to make the technology more affordable for the air conditioning industry. An inverter air conditioning system controls the compressor electronically by altering the hertz (frequency).  i.e - if the area to be air conditioned requires 50% power of the air conditioners compressor as it is close to reaching desired temperature, the invert will reduce the frequency to 25Hz (UK  50hertz ) thus running the air conditioner compressor at 50% without a need to shut the air conditioner compressor off. It makes for a air conditioner with close control on temperature and reduces electrical requirements by in some cases 60% as there is no inductive load.

R410a, Why does this refrigerant  matter?

Air conditioning system's now run on two type of gas,R410a and R407c with much older systems running on R22 which was phased out in manufacture in 2004. R410a is 40% more efficient than the older gases, it also is non ozone depleting and is easy to acquire where older gases are being phased out. R407c is a non-chlorine based refrigerant refrigerant but it still has greenhouse properties, it will be available until 2015. Air conditioning and refrigeration equipment is almost completely CFC and HCFC refrigerants, mainly running on isotropic blends.

There are two types of portable air conditioning unit on the market. One is the split type portable system which has a flexible pipe assembly which connects the inside of the portable air conditioning unit with the outside unit. The outside part is usually the fan and condensing coil (heat exchanger) and is the hot side of the portable air conditioning system. These systems are effective but generally work out more expensive than mono-block portable air conditioning units.

Portable air conditioning (mono-block) system's

The mono-block portable air conditioning unit is a stand alone portable system which has the condensing coil (heat exchanger) integral within the assembly of the unit but separate to the evaporator coil. This portable unit has a flexible duct usually 100mm in diameter which expels the hot air to the outside of the building. These systems are very popular portable air conditioning unit.

What is the difference between Mitsubishi Heavy Industries Air Conditioning & Mitsubishi Electric Air conditioning?

Mitsubishi HI Air conditioning and Mitsubishi Electric are two rival companies operating under Mitsubishi's diamond logo. The Mitsubishi group form a loose entity of independently operated Japanese companies which share the Mitsubishi brand name. Whilst the companies are autonomous, they share the brand name and trademark, as well as a common legacy. This seems to be the Mitsubishi way, let the smaller subsidiary companies have more control over what would be a gigantic business to manage. Mitsubishi Heavy Industries is Japan's largest shipbuilding and machinery maker and is a mammoth company involved in an array of industrial concerns. With nearly 150 subsidiaries, Mitsubishi Heavy Industries (MHI) operates in 11 key sectors. Shipbuilding, Air-Conditioning and Refrigeration Systems, Nuclear Energy Systems, General Machinery and Components, Paper and Printing Machinery, Steel Structures and Construction, Machinery and Plants, Machine Tools, Power Systems, Aerospace Systems, and Industrial Machinery--and produces everything from cruise ships and oil tankers, to construction machinery, newsprint machines, turbines, airplanes, gasoline engines, and gear cutting machines.
