Since the efficiency drops below a certain level of dirt, the filters require maintenance. There are different types of filters available for air conditioning systems. Many of them are cheap but not very efficient. Many filters assembled inside the ducts for air conditioning in buildings are made of glass fiber cross. These filters are inexpensive, disposable, and are available in different densities and sizes. Low density filters allow greater airflow but filter less dirt. On the other hand, the high-density filters withholds particles but allow less air flow and therefore become dirty earlier. Filters for air conditioning can be classified as the following;
High Speed Filters or Flat Filters
They are mounted perpendicularly to the direction of air flow which results in a relatively high speed step, having therefore low filtration efficiency; they are the cheapest and are also they called pre-filters. These filters are formed usually by a frame of cardboard stable, moisture resistant and filter mat. Filter media has a filtration surface allowing the dust, the air carried in suspension, is retained in its folds, so that a large accumulation of powder is obtained with reduced pressure drop and a longer duration of filters.
Low Speed Filters or Baghouses
They are mounted at an angle to the direction of the air passing through them. Its speed step is less than in the previous case and the larger surface, and is therefore more effective. They are also called baghouses and are formed by a front frame and plastic bags each chemical fiber, synthetic fiber or fiberglass.
These filters move between two coils, of which a blanket is wound the filter and the other collects the already used. Entrainment is carried out by a motor which is activated by a differential pressure switch that detects the air pressure drop when the filter is dirty.
High Efficiency Filters
They also called compact filters due to their shape. They have greater than 99% efficiency. They are usually preceded pre-filter to extend their life and their typical uses are in electronics and computer rooms, pharmaceutical production areas, research laboratories, hospitals, industrial ventilation and preliminary filtration for particulate air filters.
These filters passes the air between a parallel to the direction thereof, among which there is a strong electrostatic field ionization plate. Polluting ionized particles are deposited to the exit in another set of plates.
Activated Carbon Filters
These filters are used to remove odors and gases. They are expensive filters.
They are higher efficiency and are generally used in operating rooms and cleanrooms. The assembly is carried out as the last stage of filtration, ceiling filters, filter wall areas clean work and the own diffusers, in which together with the high demand for purity air, also require air diffusion controlled.
Do you think that air conditioning is the biggest villain in your electricity bill? You know that a well installed and dimensioned correctly device consumes less power than your daily shower. There are many questions from consumers about the energy consumption of air conditioning, so here I reveal the main myths and facts about this concern.
The installation does not interfere in energy consumption. (Myth)
If the installation is done correctly stated by the manufacturer favors the apparatus. An installation differently to the manufacturer’s recommended interferes with the operation of the consuming more energy.
One type of equipment is suitable for each environment. (Truth)
There are devices suitable for each environment size, intensity, and the flow of people.
The temperature does not interfere in energy consumption. (Myth)
To keep the air conditioning on high maximum temperature (cooling) and (heating) consumes more energy. Keep the room at a temperature between 22° C and 24° C avoids unnecessary energy costs and is more suitable for the human body.
The condenser may be in an enclosed area and has no influence on consumption. (Myth)
The outdoor unit must be in a place where there is no air circulation to prevent the return of supply air.
The inverter air conditioner is more economical. (Truth)
The inverting apparatus function as an inverter to control the speed of compression equipment. The compressor does not shut down, preventing overload and temperature fluctuations.
A device of more power consumes more. (Truth)
A device with 18,000 BTU consumes more energy than a unit of 12,000 BTU for example. But be careful because the use of a device with less power than stated greatly increases energy consumption, so the correct size is very important.
To reduce power consumption, it ideal is to turn off when the equipment is out of the room. (Myth)
To turn off and on the air condition too often leads to increased energy consumption. If when leaving the room for a short time we turned the air conditioning will be causing peak consumption at each new start.
Leaving the window open with the air conditioning on increases energy consumption. (Truth)
In addition to consuming more energy, this omission could endanger the device. Ideally, leave all doors and windows tightly closed.
Keeping the filters clean avoids unnecessary energy costs. (Truth)
Dirty filters impede air circulation, forcing the unit to work harder and therefore consume more energy.
The air conditioning does not really have to be the worst villain if used properly. So maintain and clean filters and perform preventive maintenance. You can view more relevant information at this link.
