Comparing the Attributes of Low Pressure Chiller Operation to High Pressure Chiller Operation.

Trane CenTraVac chillers continue to offer time tested and proven low pressure refrigerants including the alternative

environment friendly HCFC- 123. Trane CenTraVac chillers provide the safety of low pressure with continued product improvement in leak proof design. Consider the following benefits of low pressure over high pressure chillers.

 

Low Pressure

Medium/High Pressure

Evaporator

• Always at low negative pressure

• Always at positive pressure

 

• Air leaks inward at low rate

• Refrigerant leaks outward at moderate rate

 

• Refrigerant lost: (# air leak in) x purge efficiency*

• Refrigerant loss is into equipment room

 

• No refrigerant loss is into equipment room (vented to the

 

outside via purge)

 

Condenser

• At positive pressure during operation

• Always at high positive pressure

 

• Usually at negative pressure during inactivity (air leaks

 

 

inward)

• Refrigerant leaks outward at very high rate

 

• Refrigerant leaks outward at very low rate during operation

Monitoring

• Trane Purifier Purge is able to continuously monitor

• Only ways to monitor leak rate on high pressure chiller are

of leak rate

— periodic leak checks

 

• Refrigerant monitor as required by ASHRAE

— purchase refrigerant monitor

 

• Purge timer can be connected to building automation
