Air Conditioning and Heat pumps options to consider
If you are considering office air conditioning it is a must to consider the quality of the air conditioning and consider the amount of time you will be using it. For example, if your units are for that odd hot day in the summer months then a low function air conditioning will suffice. A low function air conditioning unit will generally do the job but lack control features that commercial air conditioning systems have as standard. For example, a 24Hr/7day timer so when your office isn't occupied the air conditioning is not running costing you money. The main manufactures in the commercial field of air conditioning are Daikin, Mitsubishi, Fujitsu which offer trouble free heating and cooling with a 7-day timer.
More commercially orientated air conditioning systems have superior mode settings for heat, cool, fan, dehumidify and auto which is often required in a office environment where the occupants may want the temperature set at different levels for separate areas. Commercial air conditioning systems are compatible for open plan office environments where one controller is required to control the area instead of a multiple of controllers in the hand of many users. Cheap systems lack automatic features which lets you set the temperature and the unit will change between heating and cooling automatically. This gets rid of the issue of a summer and winter switch-over which is a important requirement for large office air conditioning system.
Large buildings usually require a centralised air
conditioning in the form of a large capacity roof top unit with ducts
within the building to channel the air into the areas requiring air
conditioning, or a VRV (variable refrigerant volume) which is a large
capacity outdoor unit which pipes refrigerant to the indoor unit via a
extensive layout of pipe-work.
Most commercial office air conditioning systems have 3 years warranty and because they have a higher efficiency, they usually have a ECA listing (air conditioning heat pumps only) which means the end user can claim against capital gains (businesses only). At present Daikin air conditioning are the only manufacture to qualify for this scheme.
Inverter air conditioning units are recommended for daily usage:
ECA Tax allowance for commercial installations:
If you are a commercial user you will get 100% tax allowance via ECA program. This is limited to professional commercial systems and is well worth taking up as you will be able to write off the equipment & installation cost against tax owed. Take a look at the ECA web site for more information on the air conditioning ECA program.
Heat recovery fresh air system:
The commercially orientated Mitsubishi Electric Lossnay fresh air system can be utilised virtually anywhere in a office environment to extract stale air and then recover the heating or cooling energy to either warm or cool incoming fresh air. New "Hyper Lossnay Core". At only 25um (approx. 1/5 the thickness of LGH-RX3) the Lossnay core uses the thinnest paper in the world to achieve high enthalpy exchange efficiency. If you are looking for fresh air exchange the Mitsubishi Lossnay is well worth looking at and has been tried and tested for many years in home and commercial.
