The evaporator coil, which is usually installed on top of the gas oven inside the house. Mounted on a prominent and easily accessible wall, the thermostat is the most visible and interactive part of your HVAC system. Whether pre-programmed or manually configured, the thermostat instructs the system to keep your home at the desired temperature. When the temperature in your home rises or falls too low, the thermostat will activate your HVAC system to start circulating air as needed.
The oven or air controller is designed to heat or cool the air, which is then distributed to different parts of the house through ducts. Fossil fuel combustion furnaces and electric air handlers are used for this purpose, depending on the type of system in your home. The evaporator coil is used together with your oven. It is located inside a separate metal housing installed next to the oven itself.
To simplify a much more complicated process, refrigerant is pumped into the evaporator coil and, like a glass of cold water on a warm day, the coil draws heat from the air as it passes over the coil and cools it down at the same time. The cool air is then circulated through the duct network. The duct network refers to the duct system, which you can compare to pipes or channels, which carry air (heated or cooled by the system) to various parts of your home. These are the outlets that help deliver warm and cooled air from the duct system to the individual rooms of your home.
Made of high- and low-temperature safe metal or similar materials, ventilation grilles are located on the ceiling, tops of walls, or on the floor. Each vent is front with angled slats that direct them in a particular direction. In certain applications, they can be controlled or even closed manually to control the amount of heated or cooled air being sent to the room. Otherwise, care should be taken not to block or prevent airflow from the ventilation grilles, as this will affect the overall comfort of your home.
These narrow metal tubes carry the refrigerant in gas form to the condensing unit and then back to the evaporator coil in liquid form. Made of durable heat and cold resistant metal, such as copper or aluminum, these tubes bridge the gap between your home's indoor and outdoor units. When you look at your HVAC system, you only see two boxes: one that is located outside your home and the other inside your house, in the garage, attic, or basement. The outer component box is called the condenser, while the inner box is the air handler.
But you need to understand what's inside these boxes to know how your central air conditioner works. The main unit of an HVAC system includes the air conditioner, heat pump, or oven. These are the parts where the heating and cooling of your home takes place. However, they do so with the help of other internal and external mechanics.
As the brain behind a domestic HVAC system, the thermostat deserves the first mention. Basically it is a thermometer with a direct connection to the heating and cooling components, allowing you to control when the oven and air conditioner turn on. Today, there are many types of thermostats available, including programmable models that automatically change the temperature according to the program set by you. You may also decide to install several thermostats for zoning purposes.
The oven and blower motor are two main parts of a home HVAC system. The oven is quite large and usually requires its own space in the basement, attic or closet. Each oven has a heat exchanger, which starts when the thermostat asks for heat. If the oven runs on gas or oil, the burners perform the heating.
If the fuel source is electricity, electric coils heat the air. It is important that the heat exchanger remains sealed, as furnaces using natural gas or petroleum fill the heat exchanger with combustion fumes, including poisonous carbon monoxide (CO). Under normal conditions, a vent sends cooled fumes to the outside, where they are harmlessly dispersed into the air. However, if the heat exchanger is cracked, these fumes could enter your home, potentially endangering you and your family.
That's why preventive maintenance is so important. When you imagine the parts of a domestic HVAC system responsible for cooling, this is the component that normally occurs to you. It is the metal unit that is located outside the house and is responsible for expelling the heat absorbed from the indoor air to the outside. This prepares the refrigerant for another round through the evaporator coil, where it absorbs more heat and cools your home even more.
Without refrigerant, air conditioning wouldn't be possible. The refrigerant lines are comprised of copper or aluminum and run between the indoor evaporator coil and the outdoor condensing unit. Forced air heating and cooling are duct-based to distribute air conditioning throughout the house. It is easier to install the duct network during initial construction, although sometimes adaptations are possible.
Ducts should not go through the attic, garage, or access space, if possible. If this is unavoidable, ducts should be sealed and insulated to prevent them from being affected by major temperature differences between these areas and the living space. HVAC stands for heating, ventilation and air conditioning systems. This system is responsible for heating and cooling your home and includes products such as ovens, air conditioners, heat pumps, as well as ducts, thermostats and other home comfort controls.
