Why I need to know this, you may ask. But, educating yourself about HVAC system, a part of everyday life, will ultimately increase the operability and lifespan of your appliance. Though your AC repair technician in Singapore is always there, a little knowledge can save you from major expenses. So, spare yourself a few minutes and take a quick read.
HVAC is an acronym for Heating, Ventilating and Air Conditioning. A good HVAC system is engineered using the principles of fluid mechanics, heat transfer and thermodynamics to provide indoor comfort and thermal control.
Difference between Various HVAC systems
The HVAC systems deployed at industrial buildings, skyscrapers, and large interior environment and apartment blocks are different from that in your home (though the fundamental principles remain same).
- People living in cold or hot climate can use inexpensive, single stage system that is designed to produce cooling or heating.
- Advanced models involve high-speed fans to cut down on power use. These are inefficient as compared to multi-stage systems and deem to be expensive in the long run.
- Zoned systems are designed with zone valves and dampers put inside the vents and ductwork to manage the air flow. For large properties, this offers much value as it prevents the system from heating or cooling areas that are not in use.
- Some HVAC systems have added options for both humidifiers and dehumidifiers. People living in dry environment or tropics find these systems very essential.
Heating, Ventilating and Air Conditioning
The heating component is used to keep your houses warm inside during cold months. These can be forced air, radiant heat or geothermal heating systems. Forced air systems use the furnace to hear the air and disperse it via ductwork or in-room vents.
Radiant heating systems use boiler or heating stoves to disperse heat via electric heating coils or hot water tubing, installed in the floor or ceiling.
And, Geothermal systems deploy geothermal heat pump that use the constant temperature of the ground created by the sun to generate heat.
HVAC systems help to improve and maintain indoor air quality by circulating and purifying air, controlling moisture levels, removing unpleasant smells and preventing air stagnation. It performs ventilation naturally, mechanically or through a combination of both.
There are several types of cooling HVAC systems with their good and bad points. The list of cooling systems includes central ACs, split units, ductless AC, window units and portable AC.
AC circulates refrigerant that turns gas into a liquid and expels heat out of your home through the compressor. The condenser fan air cools the warm vapor refrigerant passes over finned coils and produce hot liquid.
This liquid is passed through an expansion valve and creates a low pressure, the cool liquid mist that circulates through the evaporator coil. It, in turn, absorbs heat from inside air, which is pushed outside by the system, resulting in a cool house.
Now you understand how your HVAC systems operate, and how important are they in your everyday life. We’re sure this knowledge will prepare you to maintain your system, determine what type of system you need and when do you need AC maintenance services in Singapore.
