Danfoss Turbocor TTS Series, Applications And Installation Manual

Page: 21 / 136

2.2 Refrigerant Type
Turbocor compressors are designed to be applied only with specific refrigerants. The ANSI/ASHRAE 34 Standard
(Safety Classification of Refrigerants) classification should be taken into account when designing and applying
Turbocor compressors. We also strongly recommend following the current ANSI/ASHRAE Standard 15 (Safety
Standard for Refrigeration Systems) or other applicable local standards for the mechanical room design and
application of all equipment using Turbocor compressors.
Table 2-1 Refrigerant Used with Turbocor Compressors
Compressor Series Refrigerants ASHRAE/ANSI Standard 34 Classifications
TTS/TTH R134, R513A A1
TGS/TGH R515B, R1234ze(E) A1, A2L
NOTE
l
Do not use recycled refrigerant as it may contain oil, which can affect system reliability
l
The refrigerant should be pure and stored in virgin containers
l
R513A refrigerant is only compatible with EPDM O-rings
NOTE
To ensure a reliable chiller system, all system components, most notably expansion valves, solenoid valves, and sensors, be appropriate for
application in oil-free systems as determined by the component manufacturer. In addition, all chiller system components exposed to
refrigerant should be approved by their manufacturer for use with that refrigerant.
2.3 Environment
The compressor should not be operated at an altitude higher than 3000 m.
The compressor should be stored and operated within the following ambient temperature ranges:
l
Storage: -30°C to 70°C (-22°F to 158°F)
l
Operation: -1°C to 51°C (30°F to 124°F)
l
Mains Power Applied Non Operating Limit: -25°C (-13°F)
l
Humidity: 0-95% Non Condensing
• • • CAUTION • • •
Power must be applied to all compressors on the chiller for a minimum of 24 hours prior to starting the compressors.
If a compressor is stored in an ambient condition where the humidity is at or above 85% for an extended amount of
time, the following precautions must be taken prior to giving the compressor a demand (Run) command.
l
Prior to powering the compressor/chiller, visually inspect the top-side power electronics to ensure
there are no signs of oxidation or any other signs of moisture or condensation.
l
Ensure all covers are in place and secured. The Danfoss Turbocor compressors have integrated seals in
each cover which prevent ingress of moisture and contaminants; however, if the covers are not in place
and properly secured, outside air and contaminates can intrude and potentially affect the electronics.
