HVAC systems are handy for ensuring the right temperatures within any given room and ensuring that the inhabitants are comfortable. During the summer, the system regulates temperature by warding off hot air from the room and during the winter, it supplies your places with hot air. You gain the most from the system if it is working in the best way possible. An efficient HVAC system is one that utilizes minimal energy in order to carry out its heating and cooling functions efficiently and this translates that you end up cutting down on your power bills substantially. For optimal performance of the systems, there is need for you to ensure regular maintenance of your systems.
The thermostat is responsible for the sure functioning of your furnace. It is attached directly to the furnace and incorporates a technology highly sensitive to the surrounding temperatures and controls that you use to monitor the temperatures in any given room. It is usually installed in an area that you can easily access to set the thermostat manually to an ideal temperature. When temperatures are too low, the heat exchanger blows in hot air to your preferred room through the system vents. When there is a lot of heat, the condensing unit works in conjunction with the evaporator coil to transmit cool air inside the affected spaces.
The furnace is a substantially large part of the system and it is usually installed in its own area. The unit can be installed either in the basement the closet or the attic. There are two basic types of furnaces, which are the single stage together with the two stage furnaces. These furnaces are further classified in accordance with their performance ratings. The furnace functions majorly to heat up air that is later on transmitted to various rooms in a given building. Usually the heating is possible through any of the possible heat sources, which are solar energy, heating pumps, combustion from natural gas oil, propane as well as coal, and electric resistance.
• Heat exchanger
The heat exchanger is found in the unit that houses the furnace. It starts functioning upon the starting of the furnace when as user activates the thermostat. This way it gets to create a warmer environment especially during the winter season. It functions by pulling in cool air heats it up then blows it to the rooms in your house through ducts.
• Evaporator coils
Evaporator coils are also key components of your furnace system. The do the opposite so what the heat exchanger s do. You activate evaporator coils each time you need cool air inside a given room. They supply cooled air, which the furnace blower takes up, and is forced out through vents. It works in like manner as an automobile radiator in the production of cool air.
• Condensing unit
Usually the condensing unit is installed in the exteriors of your home away from the furnace. These units have a refrigerant gas that is cooled when hot and cool air is exchanged. It is changed into liquid form through a compression and condensation process and sent to the evaporator coil through a tube. At the coil, its pressure is lowered and it changes back into gas. As the liquid evaporates, it absorbs heat resulting in subsequent reductions of room temperatures and the gas blowers are supplied with cool air. The process repeats itself when the refrigerant gas is transmitted to its place of origin.
• Refrigerant lines
The main function of refrigerant lines is to transmit the refrigerant substance through to the condensing unit and take it back to evaporator coils when it has been converted to liquid form. They are manufactured using either copper or aluminum. They are designed in such a way that they can withstand extreme temperatures.
The ducts are basically elements that transmit both cool and hot air to different rooms in your home. Usually they are made using aluminum that is of lightweight to make it easier for HVAC installation. At times they are manufactured using plastic or steel. They are conventionally run through ceilings. They are cut to allow room for vents.
These outlets are rectangular and transfer hot or cool air from the ductwork to the relevant rooms in your home. They can withstand both extremely low and high temperatures, are usually installed next to your ceilings, and fronted using angled slats. The slats direct the cooled or heated air to the room where occupants are. You can control them manually to regulate the amount of treated air transmitted to the affected room.
How does this HVAC knowledge help you?
Knowing how the various parts of the HVAC system works helps you in searching for the right system for your needs and you can easily tell if the system is encountering problems, additionally this knowledge can help you appraise the work of technicians during HVAC installation.
