Engines chiller

Engines, which are used chillers with centrifugal include the external drive and closed types of disks. External drive motors, the air in the room to cool the motor. Motor, which drives the compressor works or open. External drives, used in systems of 80 tons to 10,000 tons. Heat from the engine is excessive and should be exhausted from the room. Closed actuator motors sealed. They refrigerant is cooled motors. The liquid refrigerant falls around the motor housing. Sealed units are often used in 80-ton 2000-t systems.

Another method of circulating refrigerant for cooling system using a gas engine. Use of natural gas from the engine chillers provide faster return in some areas. The system uses natural gas engine compressor. Large blocks used scroll compressors. In smaller units, piston compressors are used. System operation, Fig. 24-70, the same as for any other chiller unit. The only exception is the system drive.
