We have a total of four similar buildings inside .These are relatively small buildings, and together they contain 22 freestanding AC units.

Our company installed these units approximately 1.5 years ago. The buildings are used for projection purposes and contain multiple projectors that generate significant heat. Due to the high heat load, additional cooling capacity was required, which is why each building is equipped with several freestanding AC units.
