I. CTV centrifugal chiller unit product characteristics
1. Overview
The Trane CenTraVac™ centrifugal chiller, for example, is one of the more reliable, efficient, low-emission and relatively quiet centrifugal chillers on the market today.
The single-head centrifugal model CVHH1550 (1,600-2,000 cooling tons) and dual-head model CDHH3050 (2,800-4,000 cooling tons) in Trane's centrifugal chiller lineup are well suited to meet the needs of customers with high-capacity centrifugal chillers for district cooling, commercial complexes, large industrial facilities and infrastructure. Its efficiency is up to 10% higher than higher efficiency units in the same cooling capacity segment, with industry-leading full-load and part-load efficiency. The dual-head unit utilizes a tandem, counter-current discharge design for the industry's highest efficiency in high-capacity applications.
2、Core features of chiller
High efficiency
◇Relative to other designs, the efficiency can be increased up to 10%.
◇Motor direct drive compressor method increases efficiency by 2-3%.
Remarks
Semi-hermetic compressor shaft seal requires less airtightness. A small amount of oil or gas leakage will not cause the system to work unstably. No speed increasing gears and other transmission devices can reduce the failure and improve the efficiency of the unit with partial load.
◇Multi-stage compression combined with two-stage economizer improves the cycle efficiency by 5-7%
◇The industry's most efficient low-pressure, new-generation, low-greenhouse-effect refrigerant
◇The combination of series connection and counter-current can be used to further improve efficiency in large cooling capacity projects.
Environmentally friendly
◇New generation refrigerant with near-zero GWP is one of the few currently available non-flammable refrigerants.
◇Low-pressure, leak-proof design can greatly reduce the probability of refrigerant leakage.
◇Air extraction device keeps the refrigerant in the unit pure.
◇Energy-saving options reduce energy consumption.
Advanced control
◇Simple design and minimal moving parts ensure the highest reliability when the unit is in operation.
◇The semi-closed motor is cooled by refrigerant, and the operating environment is clean and stable, which maximizes the service life of the unit.
◇The patented AdaptiView™ adaptive control ensures that the unit does not shut down.
◇Multi-stage compression ensures stable operation under all working conditions.
Trane's unique evaporator technology reduces refrigerant charge.
◇Supports various energy-saving applications such as cold storage and heat recovery.
