Chilled Water - HVAC Systems
Broomhall Brothers repairs, maintains, and installs chillers of all sizes.  A chilled water system uses a refrigeration cycle to create chilled water (between 45-48 degrees F)  to circulate water through fan coil units for comfort cooling. The refrigeration system may have a air cooled or water cooled condenser. The components of a package chiller (evaporator, compressor, an air or water-cooled condenser, control device) are manufactured, assembled, and tested as a complete package at the factory.  Water cooled chillers use a cooling tower to remove the heat from the building, the cooling tower may be located within the building and vented outside or located, more commonly, outside the building often on the roof. These water cooled packaged systems are available with a small foot print allowing the units to be retrofitted to any size system,  moved with the building elevator, and fits in small equipment rooms. Water cooled systems are available in 5-10 ton capacity for residential and small commercial applications to any combination of capacity to 100+ tons.

Air cooled condensers are located outside the building.  Air cooled condensers generally consume more electrical energy than water cooled.  Broomhall Brothers experience has found that while air cooled condensers may have a lower up front cost they do not have the operational life span or efficiency of water cooled condensing systems.  The most common cause of failure and short life spans is a lack of maintenance, inadequate water treatment and in air cooled packages hail damage.
