Most businesses and homes install air conditioning systems. The need to manage internal temperatures comes about from changing weather patterns. When summer comes by everyone turns to their air con systems for the needed refreshing coolness indoors. How does your HVAC system go about cooling your home?
Worth noting is that your air conditioning system functions much like your refrigerator. The main difference is that the HVAC system offers large scale cooling while refrigerators handle smaller, insulated spaces. Understanding how the system works plays a significant role in better handling and air conditioning maintenance.
The Main Components Of Your Air Conditioning System
All HVAC systems use the basic premise of expelling hot air from your home. The systems feature three key elements including the compressor, the evaporator, and the condenser. The condenser and compressor typically have an outside placement on most air conditioning systems while the evaporator is found inside the unit.
How Cooling system works
The compressor packs the liquid molecules together, and it derives the molecules from the cooling fluid/gas. The aim is to create a higher energy rise and temperature by making the liquid/gas molecules more compact. From the compressor, the gas/fluid exit in the form of high-pressure, hot gas. The heated gas then moves to the condenser where it gets cooled down and converts back to liquid form. The fluid goes into the evaporator, and its pressure drops. With the decrease in pressure, the liquid converts into gas.
Throughout the process, heat gets extracted from the surrounding air. The heat separates the liquid molecules into gas form. The outer air conditioning casing features metal fins that help to dissipate heat and expedite the thermal heat exchange process. When the refrigerant exits from the evaporator it has once again converted into a chilled gas with low pressure.

When the refrigerant exits from the evaporator it has once again converted into a chilled gas with low pressure. The process starts up all over again when the cooling gas goes back to the compressor.
Making use of a fan that connects to the evaporator, the system circulates the cooled down air within your home. Air ducts help in distributing the cold air throughout your home via vents. Your air con system keeps repeating the process until your home or business gets to the desired temperature.
The Role Of The Thermostat
Your air con system needs information about your home’s desired cooling temperature. The thermostat functions as the gateway connecting the HVAC system and the user. As the user, you input information about the desired cooling temperature and the thermostat relays it to your cooling system.
The thermostat can also adjust temperatures according to the internal environment. It shuts down the air con once internal temperatures reach the desired levels. When the internal temperatures rise, the thermostat senses it and turns the cooling system on once again. The process also keeps taking place until the air conditioning system achieves the desired ambient temperature.
