How many actions does an air conditioner have?
In its most basic description, the air conditioning process involves two actions that occur simultaneously, one inside the home and one outside the home.
What is Central Air?
A typical air conditioning system , often referred to as “central air” or “split-system air conditioning”, normally includes the following:
How does an evaporator coil work?
As the liquid refrigerant inside the evaporator coil converts to gas, heat from the indoor air is absorbed into the refrigerant, thus cooling the air as it passes over the coil. The indoor unit’s blower fan then pumps the chilled air back through the home’s ductwork out into the various living areas.
What happens to refrigerant outside?
Outside the home (sometimes referred to as the “hot side” of the system), the refrigerant gas is compressed before entering a large coil in the outdoor unit. Heat is released outside as the refrigerant turns back to a liquid and a large fan pulls outdoor air through the outdoor coil rejecting the heat absorbed from the house.
What regulates the amount of refrigerant going into the evaporator coil?
an expansion valve the regulates the amount of refrigerant going into the evaporator coil
