A 100 ton AC unit is a type of air conditioning system that is capable of cooling a large space. It is typically used in commercial and industrial buildings, as well as some residential applications. The unit is rated in tons, which is a measure of its cooling capacity. A 100 ton AC unit is capable of cooling up to 100 tons of air per hour. This is equivalent to cooling a space of up to 1,200 square feet. The unit is made up of several components, including an evaporator, condenser, compressor, and expansion valve. The evaporator absorbs heat from the air and transfers it to the refrigerant. The condenser then releases the heat outside the building. The compressor compresses the refrigerant and sends it to the expansion valve, which regulates the flow of the refrigerant. A 100 ton AC unit is an efficient and powerful way to cool a large space. It is important to choose the right size and type of unit for the space, as an undersized unit will not be able to cool the space properly. Additionally, regular maintenance is necessary to ensure the unit is running at its peak efficiency.
