The definition of an induction unit HVAC is a type of heating and cooling system that uses an electric induction motor to drive a fan. This type of system is commonly used in residential and commercial buildings, as it is a more efficient and cost-effective option than traditional heating and cooling systems. The induction unit HVAC works by drawing in air from the outside and passing it through a heat exchanger, which transfers the heat from the air to the refrigerant. The refrigerant is then circulated through the system, cooling the air before it is sent back into the building. This type of system is more efficient than traditional systems because it does not require a large amount of energy to run, as the electric induction motor is more efficient than a gas or oil-powered motor. Additionally, the induction unit HVAC is much quieter than traditional systems, making it ideal for residential and commercial buildings.
