Step One: Thermostat calls cold air.
Imaginable the thermostat as your brain of one’s air conditioner — it tells your AC when you ought to activate and off. In the thermostat, electronic sensors detect when the indoor temperature rises above your set temperature. If you have a general change in temperature, it sends a signal towards control board rising conditioner, telling it to change on.
Step Two: Heat is pulled from warm, indoor air.
Before we dive on the cooling process, let’s start by debunking a typical misconception: An ac doesn’t actually create cold air from scratch. Instead, it removes heat from your home’s air. So how is heat removed?
First, warm is pulled on the indoor part of this AC (called the air handler) via the blower, which you can imagine as a huge fan. The blower pulls in this particular heated air via the return vent, the opening that enables air to enter your AC system.
Step Three: Cool air gets pushed back to your house
When the air is cooled, it’s pushed right back into your house via your duct system. Your air duct method is a number of hollow tubes or metal sheets that carry cold air to parts of your house. This cold air exits the ducts via supply vents, which are positioned in just about every room.
Step Four: The heating that’s removed gets dumped outside
Remember back Step two how refrigerant absorbs heat from heat? Well that heat should go somewhere; it doesn’t just magically disappear. So how will it go? It’s released to the outdoor air. The truth is, as soon as the refrigerant absorbs heat, it travels to your AC system’s outdoor unit, known as the condenser.
Step Five: The cooling cycle repeats
If the refrigerant releases each one of its heat, it returns to its liquid form. Then an refrigerant is carried returning to the indoor unit and passes through an expansion valve, which controls the flow on the liquid for the evaporator coil.
