It is often through a central, whole-home Heating, Ventilating, and Air Conditioning system that most of the homes are heated and cooled.
The more you know about your HVAC the better it is as the HVAC may well be one of the most expensive and energy-hungry systems in the home.
A well-informed homeowner will have a healthier and more comfortable home and they will also be saving a lot of money on it.
The components of the HVAC system
As some of the components are installed inside the home, and some of the parts are also installed on the outer side of the home when it comes to the central HVAC systems which can also be termed as the split systems.
Inside your home you will find the furnace and the evaporator portion of the air conditioner such as the oil, gas or electric usually installed the basement, attic or a closet.
Serving to both the furnace and the air-conditioner you will also be finding the blower or the air handler.
The tubes which act as pathways to deliver the heated or the cooled air to multiple rooms in the house are the ducts which are attached to the blower.
Your HVAC system will not have a separate furnace if it is a heat pump. In the summer, a heat pump works like a regular air conditioner and then in the winters serving to both the cooling and heating purposes, they essentially work in reverse.
And this is well explained by Dave Moody, who is HVAC pro with Service Experts. The indoor and the outdoor components are still there in the heat-pump system.
You will also find the compressor and condenser components of the ducted air conditioning Sydney which is mounted in a metal cabinet with a large fan outside the house.
With the ducts which are entering through the wall of the home, one alternative to a split –system is called a “packaged” system in which all the components are well installed in a single unit which is there on the outer side of the home.
For a homeowner who does not want to waste space on the interior of their home with the heating and cooling equipment, these units may be a lot more preferable.
For some limited fresh air, most home relies on infiltration or air which seeps through the gaps and cracks in the shell of a home.
As a big factor in human health issues, mechanical ventilation systems are becoming far more commonplace as the indoor air quality is increasingly implicated as what is stated by Service Expert’s Moody.
Heating
By burning oil or has in a sealed chamber, is how the oil or gas furnaces work. Around the outside of the chamber, the air is circulated and then absorbs heat prior to it being circulated back into the home through the ducts and this is all done by the blower.
Some of the combustion gases are lethal which the byproducts of burning oil and gas are. Through a metal or plastic flue pipe, those gases are vented to the outdoors.
For the fire in the combustion chamber, the new system includes a second pipe which gathers the air from the home outside. And for this purpose, the older system pulled the conditioned air from the interior of the house.
Cold air from outside was pulled through the cracks in the building’s shell making the home feel drafty and cold and lowering its efficiency as that air was used in combustion.
Converting electricity to heat the electric furnaces uses the electric strip elements. As it passes by the red-hot heating element, air from the house absorbs heat. Through the ducts, it is then when the air is distributed.
Resistance heating is generally considered a less efficient and more expensive way to heat a home while being quite simple, reliable and safe.
Cooling
Through the electric air-conditioner or the cooling cycle of the heat pump is through which cooling is achieved. A compressor then compresses the refrigerant gas into a high-pressure gas.
Through a radiator-like condenser coil of copper tubing and aluminum fins where a large fan transfers the heat to the outdoors as the compressor pumps the high-pressure gas.
Through the copper tubing then the cooled compressed refrigerant liquid is pumped into the house. And this air also arrives at the radiator-like evaporator coil. It vaporizes from a liquid to gas once again under very less pressure.
And it is under this less pressure that it vaporizes from a liquid to gas.The high humidity in the air which makes us feel sticky or clammy is what the past of our discomfort comes in the time of summer.
