UTC Klimatechnik GmbH
Carrier water-cooled liquid chiller with turbo compressor - two-stage
Rated Cooling Capacity: 2800-10500 kW
The Carrier 19XR/19XRV turbo refrigeration machines, boasting a coefficient of performance (COP) of up to 6.5 (AHRI conditions) and an integrated part load value (IPLV) of up to 7.4, or 10.5 with variable frequency drive (VFD), deliver exceptional performance. Achieving energy efficiency ratings of up to 6.8 (EER), these machines utilize proven technology specifically designed for chlorine-free refrigerants:
- Intermediate stage economizer for efficiency
- enhancement and performance augmentation
- Unique hermetic compressor concept: Aerodynamic dual-stage impeller-diffuser without guide vanes to meet high head applications while ensuring stable operation
- Motor cooling by spraying liquid refrigerant on the motor windings
- Compressor control through variable frequency drive (19XRV) for maximizing machine energy efficiency
- Utilization of high-performance evaporator and condenser tubes
- Integration of an expansion subcooler into the condenser
- Patented float valve technology for optimized subcooling and optimal refrigerant level in the evaporator
These advantages, coupled with high modularity, efficiency, cost-effectiveness, and compact dimensions, allow the use of two-stage Carrier turbo refrigeration machines 19XR/XRV in high-performance water-cooling applications in HVAC, heat pump technology, energy recovery, ice storage, shipping, VFD, and high-voltage environments.
