5. Unobstructed flow of condenser air is essential to maintain chiller capacity and operating efficiency When determining unit placement careful consideration must be given to assure a sufficient flow of air across the condenser heat transfer surface Two detrimental conditions are possible and must be avoided warm air recirculation and coil starvation Air recirculation occurs when discharge air from the condenser fans is recycled back to the condenser coil inlet Coil starvation occurs when free airflow to the condenser is restricted Condenser coils and fan discharge must be kept free of snow or other obstructions to permit adequate airflow for satisfactory unit operation Debris trash supplies etc should not be allowed to accumulate in the vicinity of the air cooled chiller Supply air movement may draw debris into the condenser coil blocking spaces between coil fins and causing coil starvation Both warm air recirculation and coil starvation cause reductions in unit efficiency and capacity because of the higher head pressures associated with them The air cooled CGAM chiller offers an advantage over competitive equipment in these situations Operation is minimally affected in many restricted air flow situations due to its advanced Adaptive Control microprocessor which has the ability to understand the operating environment of the chiller and adapt to it by first optimizing its performance and then staying on line through abnormal condition

DOE 2 or TRACE you can determine whether the anticipated energy savings justify the use of variable primary flow in a particular application Existing constant flow chilled water systems may be relatively easily converted to VPF and benefit greatly from the inherent efficiency advantages Application Considerations Water Temperature Leaving Water Temperature Limits Trane CGAM chillers have three distinct leaving water categories e standard with a leaving solution range of 42 to 65 F 5 5 to 18 C e low temperature process cooling with leaving solution range of 10 to 65 F 12 to 18 C e ice making with leaving solution range of 20 to 65 F 7 to 18 C Since leaving solution temperature below 42 F 5 5 C results in suction temperature at or below the freezing point of water a glycol solution is required for all low temperature and ice making machines Ice making control includes dual setpoint controls and safeties for ice making and standard cooling capabilities Consult your local Trane account manager for applications or selections involving low temperature or ice making machines The maximum water temperature that can be circulated through the CGAM evaporator when the unit is not operating is 125 F 51 7 C Evaporator damage may result above this temperature Leaving Water Temperature Out of Range Similar to the flow rate limitations above many process cooling jobs require temperature ranges that are outside the
