Water-cooled chiller with a cooling tower
by HVAC Builder
Open this system in HVAC Builder Load it into the 3D builder, adjust it to your project, and solve it against your own climate — or drop it into a building model and simulate a full year.
A compact water-cooled chiller: supply fan, face-and-bypass dampers around an indoor air coil, inverter scroll compressor, pipe-in-pipe condenser on a closed condenser-water loop, and an evaporative cooling tower with its own fan and pump. The bypass trades a little total capacity for a markedly drier supply. Published as an example — the figures below are solved from this model, not copied from a datasheet.
