Not everyone is familiar with the various types of Heating and Cooling devices that exist to make heating and air conditioning possible. As time goes on, HVAC equipment changes for the better, generally being more cost effective or energy effective. Understanding some of the basic pieces and their functions might help develop a better understanding of how a Heating and Cooling system operates.
Not all A/C systems are the same, but a lot of them consist of the very same parts that are required to work together as a system. Whether you have the ability to do it yourself or you need to call an A/C expert, these parts that are regularly working together to keep the overall system running smoothly. Let's do a rundown on some A/C equipment.
HVAC Coils
There are two kinds of A/C coils in a normal A/C system; a condenser coil and an evaporator coil. The condenser coil help in heat exchange, and just like it states in the name, it condenses the hot refrigerant gas by being pumped outside and put under pressure to become liquid. The condenser coil then assists to release the heat, and the refrigerant comes back inside to the evaporator coil. The evaporator coil, usually discovered in the air conditioner, is where the home air goes through to be taken in and become cold air. This air is then blown through the furnace tips ducts.
Air Handler
An air handler is an indoor metal box used for both heating and cooling. It includes the blower, which is what sends the air through your house, along with the evaporator coil. Depending upon the size of the A/C system, it's available in various sizes and various speeds. It is among the most fundamental parts of the HVAC system. It's how your cool air and warm air reaches you.
Refrigerant Lines
Refrigerant lines are the metal tubes that the refrigerant goes through on its method to the evaporator coils. Refrigerant is what causes the cooling. The condensing unit vaporizes the liquid into gas and goes to the evaporator coil as liquid. These tubes can deal with lots of temperatures, from typical to extreme.
Heating system
The heating system is a big unit, usually concealed away in a basement or a closet. The heating system is the A/C system's heat supplier. Heat is sent from the furnace to all the ducts of the house. There are various types of heaters with various types of heat sources. For example, a gas heating furnace utilizes gas and oil.
Single Stage Heater vs. Two-Stage Heating System
The single stage furnace has an on and off function, permitting the user to have full control. The two-stage furnace overcomes the thermostat. The thermostat is used to figure out whether hot air or cold air is needed. The two-stage heating system is beneficial for conserving energy since the furnace turns off by itself when the temperature reaches a proper level.
Heat Exchanger
A heat exchanger is found in every heating system unit. It's a really fundamental part and it should be kept clean. First, the thermostat activates the heater. Then, the heat exchanger goes into action. Cool air enters into the heat exchanger, which is pulled from the rooms of the house or structure, and is heated up to be distributed back in.
Thermostat
A thermostat is the controlling component of the furnace. It senses the temperature and alerts the heater. Most of them are positioned so that they can be quickly accessed and changed by those inhabiting the home or building. Depending upon choice, they can be set or manually set. A programmable thermostat is advantageous for controlling the temperature during all times of the day. A programmable thermostat can even assist to conserve money and energy.
Ducts
Ducts, or ductwork when describing the system of ducts, are generally made from aluminum and frequently positioned within the ceiling when the house or structure is built. Ductwork is accountable for moving air to various areas of the home. It is necessary to keep the ducts insulated.
Vents
A vent is a rectangle-shaped opening in which the air transferred from the ducts is released. The metal utilized to make the vents is able to deal with both the cold and hot air temperature levels that travel through. Take a look on or near your ceiling. They're probably there.
Not all vents are referred to as vents. Some have particular names. An example of one is a supply register. It's a little rectangle-shaped vent that brings the warm and cold air. The reverse of this is the return vent. The return vent is larger and made to, you guessed it, return the air. It gets gone back to the Heating and Cooling system to go through the process of being warmed or cooled again.
Conclusion
There you have it; more behind heating & cooling than you most likely would like to know. As long as your house is receiving the appropriate heating and air conditioning, you may not believe twice about the operations behind it. Now when you're at house or any building taking pleasure in the comforts of one or the other, you'll be knowledgeable about what devices is making it air conditioner not blowing cold air possible.
