Working of an HVAC System
HVAC is meant for heating, ventilation and air conditioning. The goal of HVAC is to control the temperature of air inside the assigned “Air conditioned” space as well as control of moisture, filtration of air and supply of outside natural air for control of oxygen and carbon dioxide levels noticeable all around the conditioned space, main control of the development of air or drought. Every one of these elements comprises an efficient HVAC system.
Main Parts of the HVAC
Every HVAC system mainly consists of the furnace, heat exchanger, evaporator coil, condensing unit, refrigerant tubes, thermostat, ductwork, vents and the heat pump.
Importance and duty of each part of the HVAC are mentioned below.
1. The furnace: The furnace takes up a maximum share of the space in an HVAC system. It is generally present in the basement behind a door that nobody ever opens, yet it’s a major part of an HVAC system. Its function is to move air from the heat exchanger into the air channels(ducts). The furnace is typically confounded with boilers, yet they’re separate parts.
2. The heat exchanger: This part is mentioned above but it’s not the part of the furnace. It’s situated inside the furnace, yet the heat exchanger has its own duty. It adds heat to the approaching air from the ignition chamber.
3. The evaporator coil: This part is additionally present in the furnace, yet is responsible for an absolutely different job. A refrigerant (a liquid that causes cooling) travels through the evaporator coil, which ingests heat from air passing over it.
4. condensing unit: The condensing unit resembles the evaporator coil. Inside the cube shape formed unit, the condensing unit too exchanges heat with the air that is blowing it, yet dissimilar to the evaporating coil, it emits heat.
5. The refrigerant tubes.: These metallic tubes interface the evaporator curl with the condensing coil, which generally means that the refrigerant tubes join the inner and outer air HVAC units. They’re intended to contain cooling refrigerant under an extensive range of temperatures.
6. The thermostat: This small portion generally on the wall on the main level of the home, and, depends upon what temperature you set it at, you can turn on your air conditioning or heating system. It’s best to have a programmable or “smart” thermostat to adjust your home’s temperature regardless of the possibility that you’re not there, which implies that you can minimise your energy bill.
7. The ductwork: The air ducts are having the duty of moving air all through the home. Air comes into an HVAC system through specific segments of the ductwork and is spread to rooms through different areas.
8. The vents: As the air goes through the ductwork, it enters into the room through vents. Users know about the rectangular covers that immediate and take air.
9. The heat pump: In hotter months, the heat pump takes heat from house or room to the outside. And in the colder months, it does the inverse.
All the HVAC systems consist of the parts mentioned above, and each of the mentioned components relies on the others to function in the proper manner and efficient way.
