HVAC refers to heating, ventilation, and air conditioning systems used in residential, commercial buildings, and industrial plants. A reliable HVAC system provides fresh outdoor air to supply high-quality indoor comfort. An excellently performing HVAC should provide indoor comfort by using principles such as fluid mechanics, heat transfer, and the principles of thermodynamics.
How Does An HVAC Work?
Heating, ventilation, and air conditioning functions work together to achieve optimum thermal comfort and quality indoor air. There are parts of HVAC that every homeowner should be familiar with long before the system breakdown. Call a qualified Ft. Lauderdale HVAC technician when you realize your system is underperforming.
You don’t have to learn the hard way. So, let’s get started with these basics.
1. Air duct
Air forms the primary starting point in a ventilation cycle. The air duct sucks air, passes it through a filter, and then draws it into the main circulation system. Always inspect the air duct for dust, grime, and debris build-up. Dust and clean the filters to avoid air block. Use a 10″ duct fan for the perfect airflow for your HVAC system
2. Condensing unit
This is the outdoor part of your HVAC unit. Here, the refrigerant gas cools down by exchanging heat with fresh air from outside. The gas condenses to form a liquid that is sent back to the evaporator chamber. The liquid transforms into a gas again and is sent to the outside, thus cooling the air.
3. Evaporator coil
The evaporator coil is a set of coils located outside the furnace chamber. They come into play when cool air is required to cool the warm air from inside.
This is a large compartment usually placed in the garage or a closet. There are two types of furnaces: one-stage or two stages. A furnace typically operates on propane or natural gas. The energy efficiency rate is most critical because the higher your energy efficiency, the lower your bills.
5. Heat exchanger
The heat exchanger is regulated by a thermostat found inside the furnace. It’s triggered to heat when warm air is required.
Vents are rectangular metallic pieces. They also have slats for convenient air direction control. These are installed during construction and are located in the ceiling on the floor or near the ducts.
HVAC SYSTEM’S FUNCTION
The heat generates heat to absorb heat and cool warm air. It may use gas or solid fuel. Because this part is constantly under extreme temperatures, it has to be made from strong stainless steel. It must also have temperature resistance alloys to prevent heat damage.
This is a cyclic process that involves replacing stale air with fresh cool air from outside to control the temperature in a room. Ventilation comprises the free circulation of air within and around a room and the outside exchange of air.
Air conditioning provides humidity to cool a room. When air filters trap from outside into the system, dust, debris, and pollen, then it is circulated throughout the room.
HVAC refers to heating, ventilation, and air conditioning systems used in residential, commercial buildings, and industrial plants. A reliable HVAC system provides fresh outdoor air to supply high-quality indoor comfort. An excellently performing HVAC, like one regularly serviced by a reputable HVAC Las Vegas company, should provide indoor comfort by using principles such as fluid mechanics, heat transfer, and the principles of thermodynamics.
These are HVAC basics that will help you understand how the system works. When there are challenges, seek the services of a professional technician to have the HVAC checked and fixed.
