Heating, Ventilation and Air Conditioning For Your Home
For many areas of the country, heating and cooling systems within your home are not a luxury, they are a necessity. Extreme summer heat and winter cold can affect the comfort and safety of you and your family. Understanding how heating, ventilation, and air conditioning (HVAC) systems work will help to plan a efficient, reliable, and comfortable environment for your home.
Air Conditioning Systems
How it Works - Air conditioning systems follow the same basic principles as refrigerators. Freon, a grouping of several neutral substances that are gases at room temperature, is compressed within a series of thin metal coils. It is compressed to the point that it exists as a liquid within these coils, similar to the substance within aerosol cans. This liquid is fed through the thin metal coils, until it reaches an expansion valve, where it converts back into its gaseous form.
When the Freon is converted from liquid to gas, it loses heat energy, making it very cold. This is what creates the cool air that is blown into various rooms of your home. All air conditioners follow this format; however, there are a variety of models that execute this cooling effect. here is what you need to know when it comes to shopping for an air conditioner.
Air Conditioner Varieties
1. Room AC Units - These models are used to cool only a couple of rooms, at most. They are generally cheaper than central systems, but they are not as efficient. You can use anywhere from a 115-volt to a 230-volt household circuit to power these units, depending on their size and power.
2. Split-System AC Units - These models split the hot and cold portions of the air conditioning unit into interior and exterior parts. The compressor and heated coils are placed outside, while the cold coils and expansion valve are inside. The cooled air is circulated through a series of ducts throughout the building, allowing you to avoid cumbersome and noisy window air conditioning units.
3. Chilled Water Units -This system is typically only effective for larger buildings, rather than smaller homes. Chilled water systems cool water, sending it through pipes throughout the structure.
4. Alternative AC Units - There are a number of other cooling systems as well, including geothermal pumps and active and passive solar systems.
How it Works - Heating systems involve a furnace or boiler, fuel, carrying agents (ducts, pipes, or fans), and a heat regulator. Heated air is generated in the furnace or boiler by using various types of fuel. The heat can be either forced air or hot water, and distributed to various portions of the building through metal ducts or copper pipes. Find out more on home heating options.
Adding a home heating system to your existing home can be an expansive process. You need to determine the most efficient type of system to use, the best location, and the most effective distribution of heated air. Depending on exactly what you would like for your home, you may choose to use a stand alone room heater, a radiant panel, or a baseboard heater, among others. We will list a few of the most popular home heating systems below:
Determining the best heating and air conditioning solutions depends on exactly what you would like for your home or building. There are many options out there that will fit your individual needs. You should research each of these systems to ensure that you are getting the most efficient and effective system, so that you and your family are comfortable within your home.
Proper home ventilation is a key factor in maintaining a healthy, comfortable, and safe environment for you and your family. Without a working ventilation system, you could be harming your heating and cooling systems, building up moisture within your home, or increasing pollutants in the air that you breath. There are three basic ways to provide proper ventilation in your home. These are natural ventilation, spot ventilation, and whole house ventilation. Below is an explanation about each type of ventilation strategy.
