While an air conditioner’s main function is to cool or heat the air, it’s important to also consider the quality of the air it produces. Midea explains why.
A good quality unit should not only take care of the temperature in your home but also the quality of the air the occupants breathe.
As one of the world’s leading brands, with sales of over 30 million units each year, Midea places great emphasis on both the filtration systems and the energy efficiency of its air conditioners.
A Midea split system removes over 90 per cent* of pollen, dust, smoke and other microscopic airborne particles that may contribute to respiratory problems like asthma and hay fever.
The air conditioners use two different types of filters. First, the active carbon and dust filter, which is made up of active carbon and electrostatic fibre, helps to eliminate certain kinds of odours, such as ammonia (NH3), and helps to deactivate harmful chemical gases, such as formaldehyde (HCHO).
Formaldehyde resins are used in many construction materials and it is one of the more common indoor air pollutants in the home. It is also emitted by paints, varnishes, floor finishes, furnishings and cigarette smoke.
By forming positive positions on the filter surface, the electrostatic fibre filter traps small dust particles, smoke and pet fur to aid in preventing allergic reactions.
The other form of filtration Midea uses is the bio filter, which is a biological enzyme, and eco filter which catches very small airborne dust particles and helps to neutralise bacteria, fungi and microbes.
A biological enzyme dissolves the walls of bacteria cells, reducing the problem of re-pollution seen in many other air conditioning units that don’t have filtration.
Trevor Francis, Midea product manager at Castel Electronics, says to maintain efficient filtration, air conditioners should be regularly cleaned and the filters need to be maintained according to the schedule in the Midea user manual.
In terms of energy efficiency, Midea is also at the forefront with their split ducted and cassettes featuring a remote on/off port to enable the connection of external timer switches, so that air conditioning systems only operate while there are occupants in the building.
Midea VRF systems also have this capability and can also be interfaced to motion sensors to ensure that when offices are unoccupied, the system switches off.
The VRF systems have also been designed to be able to be interfaced to key card controllers.Midea found that this remote port was being requested more as developers strive to increase the energy efficiency of their commercial premises.
The motion sensors can be easily installed on the wall or ceiling, have a wide detection angle of up to 100 degrees and a minimum of four metres. They are powered from the indoor unit display, again saving energy as no additional power supply is necessary.
Settings can be configured at installation so that the unit switches off either half an hour or one hour after occupants leave the office. Units are switched back on automatically once occupants re-enter the office.
With over 40,000 employees and 85 testing centres, Midea is a world leader in air conditioning technology, producing an extensive range of state-of-the-art inverter and fixed speed split systems, window, portable, ducted multi-head and a comprehensive range of commercial systems, including VRF products.
