The SpacePak ICS series of air-cooled water chillers providecompact, efficient and reliable cooling in applicationswhere placement of the air-cooled chiller outdoors isimpractical or undesirable. Locating the chiller indoors andducting the condenser air greatly minimizes the noise heardoutside to the benefit of the building’s occupants andneighbors. SpacePak ICS series units are typically installednear an outside wall or converted window opening foraccess to outside air for the intergal air-cooled condenser.They are ideal for larger homes wanting multiple zones.

Typical Water Piping Arrangement

Short Water Piping Loop ConsiderationsIn systems with relatively short water piping loops, the volume of the water in the system can be insufficient causingswings in water temperature and short cycling. In these cases a chilled water storage tank should be installed in thereturn water piping before the chiller. This will increase the volume of the water in the system thereby reducing thefluctuations in return water temperature and reduce compressor cycling. The use of three way valves at the evaporatorcoil (in lieu of 2-way valves) and hot gas bypass is also recommended. Typically allow a minimum of 5 GPM per ton ofchilled water storage.
