A Carrier 7.5 Ton Rooftop Unit is a type of air conditioning system designed for commercial and industrial applications. It is designed to provide efficient cooling for large spaces, such as warehouses, factories, and other large buildings. The unit is installed on the roof of the building and is powered by electricity. It consists of a compressor, condenser, evaporator, and other components. The compressor is responsible for compressing the refrigerant gas, which is then passed through the condenser to cool it down. The cooled refrigerant is then passed through the evaporator, where it absorbs heat from the air inside the building. The heat is then expelled outside, cooling the building. The Carrier 7.5 Ton Rooftop Unit is designed to provide efficient cooling for large spaces, while using minimal energy. It is also designed to be easy to install and maintain, making it a great choice for commercial and industrial applications.
