WHAT DOES HVAC MEAN?
HVAC refers to Heating, Ventilation and Air Conditioning. An HVAC system is used to provide desired heating, air circulation and cooling in homes, motor vehicles and air planes among others to the end user’s comfort, in tandem with acceptable indoor air quality.
IS HVAC IMPORTANT?
HVAC Systems ensure that the indoor environment is maintained at conducive levels in which individuals and equipment that requires specific storage and operating temperatures are sustained. In a facility set up and rooms, pollutants, odor and bacteria are reduced by use of a well set ventilation system.
An HVAC system in addition improves the quality of indoor air in circulation, ensuring that the air inside is well filtered and clean, almost free of dust, pathogens and germs.
The process of creating, controlling and maintaining desired temperature, humidity and air purity in indoor spaces, independent of outside conditions is defined as air conditioning.
It is a machine that is used systematically for air conditioning.
TYPES OF AIR CONDITIONER
- SPLIT TYPE AIR CONDITIONING
Split type air conditioners have two components; an indoor unit and an outdoor unit. Examples of split type air conditioning units are:
Wall Mounted Air Conditioners: The indoor unit is placed on a wall, close to the ceiling(on a high level) and are ideal for offices, living rooms and server rooms. The outdoor unit is placed at a place the installer sees fit to allow for pipping works as well as drainage system. The installer chose the wall that ensures even distribution of air.
ceiling Cassette Air Conditioners: the indoor unit is mounted on the ceiling , with the outdoor unit placed outside of the building. These Ceiling Cassettes turn to cool a wide area and do not take Much space are preferred most in banks and office spaces. They add beauty to the space in which they operate.
Under Ceiling Air Conditioners: these come with a design that enable them to lift air in a vertical manner into the indoor unit and release the conditioned air horizontally along the ceiling. Another designs allow for air release from it’s four sides.
- SINGLE UINT (MONO-BLOCK) AIR CONDITIONERS: These type do not have an outdoor and indoor unit, rather, the the two are merged as a whole (one single unit).
Examples of single unit air conditioners include:
Window Mounted Air conditioners: A square whole fitting the size of the air conditioner is created and the air conditioning unit is installed with the front end facing the inside and the rare end facing outside of the building.
Portable Mobile Air Conditioners: These do not require any mounting structures and are directly placed where the conditioned air is required. They are usually used for smaller applications.
DO AIR CONDITIONERS RUN ON SINGLE PHASE POWER OR THREE PHASE POWER?
Some air conditioners are designed to run on single phase power whilst some are designed to use three phase power. Based on the power supply available and the nature and how big the room is, an air conditioner has to be selected that will meet the desired needs. Some ceiling cassette air conditioners do require three phase power to run the outdoor unit and single phase power to run the indoor unit.
WHAT DOES BTU MEAN?
BTU stands for British Thermal Units. BTUs number indicate the amount of heat an Air Conditioner can remove from a room. The smaller the room, the smaller the BTUs number and the larger the room, the higher the BTUs number.
