A 10 ton HVAC rooftop unit is a large air conditioning system that is typically installed on the roof of a commercial building. It is designed to provide cooling and heating for the entire building. The unit is typically made up of several components, including an evaporator coil, condenser coil, compressor, and fan. The evaporator coil is responsible for absorbing heat from the air inside the building and transferring it to the refrigerant inside the unit. The condenser coil then releases the heat outside of the building. The compressor then pumps the refrigerant through the system, and the fan helps to circulate the air throughout the building. A 10 ton HVAC rooftop unit is capable of cooling and heating large commercial buildings, and is typically more efficient than smaller units. It is important to ensure that the unit is properly sized for the building in order to maximize efficiency and ensure the building is properly cooled and heated.
