All You Need To Know About HVAC Systems

What is HVAC ?
HVAC means Heating, Ventilation and Air conditioner. It is the technology of making indoor environment comfortable. It has three functions - heating, ventilating and air conditioning that are inter-related. It should be installed and operated with components like computing hardware, fire protection, security system, etc.

Operation of HVAC
HVAC is the system that unites different components that cool and heat your home. Dual duty is performed by ventilation system and heat pumps for air conditioning and heating.

• Air conditioning system: Mostly air conditioning unit is utilized in HVAC systems. This works by removing moisture and heat from the air and throwing the cool and filtered air in to ventilating system. The warm air is cooled by pipes known as evaporator coil. A liquid known as refrigerant is filled in these pipes. Refrigerant converts liquid in to cool gas when taking warm air thereby absorbing heat from air. Finally a fan blows the air through ventilation systems and cools the room with conditioned air.
• Ventilation system: These systems plays an important role in cooling and heating process. If there is any blocking or any problem in the duct work, functioning of this system is greatly effected. As the entire function is related to these systems, it is important that you check the system to ensure its working condition.
• Heating systems: Heating systems are similar to air conditioning systems. The air is heated by heating pipes The cool air from indoor is taken away, then warm air is blown. Energy consumed is less when compared to the amount of heat produced by heating systems. Heat produced by heating pipes is thrice the times the energy consumed by it.

Maintenance of HVAC systems

• If the filter is clogged with dust and appears to be dark, replace them. Filter needs to be changed more frequently if you are having pets.
• Area around the outdoor units of air conditioners should be kept clean.
• Checking the pipes that are filled with refrigerant and replacing if it is damaged.
• A cup of bleach water must be poured frequently in the drain pipes to avoid it getting blocked.
• Out door units must be checked regularly especially during rainy season and spring season, so that any remains like twigs, leaves, etc can be cleared.
