A cooling system in a commercial building typically consists of a Chiller, which works like a giant fridge, transferring cooling energy to water. The water is pumped around a primary circuit containing just the chiller. Energy is removed from this primary circuit to a secondary circuit around the building to Fan Coil Units and Air Handling Units. These have heat exchangers moving energy from water to air to keep you cool.

The efficiency of this entire process is complex. However by being efficient, you can save money, be more comfortable and make all the equipment (which is expensive) last years longer.

Areas where performance have been improved are:

• Maintenance.
• Ensuring that energy is not lost by direct heat exchange from hot to cold water.
• Ensuring energy is not unnecessarily lost to dehumidification.
• Ensuring that unnecessary energy is not lost to friction as fluids move.
• Maximising the efficiency heat exchangers.
• Reducing heat losses from mechanical equipment.
• Ensuring that equipment does not remain hot at night. This can cause damage to stationary equipment, for instance to bearings.
