Inverter Air conditioning systems explained
debate of whether to have inverter air conditioning or fixed speed air
conditioning is one all new comers to the market have to ask themselves.
Inverters are generally 40% more expensive initially but the the
benefits far out way the cost when the equipment is used on a regular
basis. With the recent change over from old air conditioning refrigerant
R22 to R410a inverter air conditioning technology has been boosted
R410a runs at a much higher pressure and temperature than the older gas
thus being better for heat pump applications. Most modern day systems
are actually better at heating in kW / Btu than its cooling output.
i.e.- If you were to purchase a 3.5 kW wall mounted inverter air
conditioning heat pump system then you would see that its heating output
would be somewhere in the region of 4 kW / 13000 Btu. The stated rating
on the box is always in cooling output. Inverters air conditioners do
not have the high inductive power rush associated with fixed speed non
inverter air conditioning which are renowned for draining huge amounts
of energy when they start up, sometimes lights are known to dim. This is
said to save on a well used system up to 60% on a annual electricity
bill. Fixed speed is being phased out by many manufactures within the
next few years
Air conditioning systems in well used environments such as server rooms or offices will benefit from inverter technology as companies are suddenly starting to wake up to the fact these systems will save money and reduce CO2 at the same time. What type of inverter air conditioning system will fit your needs depends on your initial budget and the environment that requires cooling or heating. The cheapest and generally the easiest to install is the wall mounted inverter air conditioning systems. These are the most popular inverter air conditioning control as any air conditioning sales company will tell you. The wall mounted unit comes in inverter air conditioning heat pump format, not so often cooling-only but they are available in brands such as Daikin Air Conditioning and Mitsubishi Electric Air Conditioning. These wall inverter air conditioning units ideally require being mounted on a internal wall that is also a outside wall of the building. If the unit cannot be installed this way then a Condensate Pump will be required to take away the condensate water generated by the cooling of the air conditioning unit.
The cassette inverter air conditioning system is designed to be concealed in a ceiling void, usually the space in the void should be around 300 mm minimum. The cassette air intake is in the middles of the assembly and the conditioned air will come out of the four side louver vents of the unit. Theses units are more intensive to install and 9 out of 10 installations will require a condensate pump. Cassette units are a professional way of air conditioning a area.
The best way to air condition an area in
a completely concealed way is a ducted inverter air
system. These units come in slim format of around 285 mm to fit into a
tight area. Concealed away in a ceiling flexible ducting would come off
the spigots of the unit being ducted to the area and out through the
outlet air grills. As well as supply air grills, return air grills will
be required to let the air return to the air conditioning unit. By far
the ducted unit is the professional way to air condition a environment.
Under ceiling units are as the name suggests made to fit under the
ceiling. These units can also be mounted on the ground as a floor
mounted unit. These units come in high output format with some
manufactures having 25 kW format. Installation of these air conditioning
units is not to intensive but condensate is worth considering as these
systems do not come with a internal pump. Therefore, the ideal would be
