CHILLER - CENTRIFUGAL CHILLER

Hitachi Introduces New High-efficiency HFC134a Centrifugal Chiller

Hitachi has released new higher-efficiency centrifugal chillers featuring HFC134a refrigerant.
Two types are available; the standard type (14% improvement over the conventional models).
These efficiency improvements have been achieved by our advanced technology producing reduced
flow loss of HFC134a refrigerant gas, lowered energy loss in the rotating body and the motor's
electrical circuits, and by the use of 2-step economizer cycle.


Reduced volume of refrigerant emitted to the atmosphere

High-pressure HFC134a refrigerant does not cause outside air inflow nor require a purging unit. This allows eliminating emission of the refrigerant to the atmosphere caused by purging operation. In addition, installation of service valves for the oil filter and meters enables their replacement by partial disassembly, reducing the refrigerant emission during maintenance.

FEATURES:
1. Ozone Layer Protection and Global Warming Prevention

• Use of HFC134a refrigerant having an ozone depletion potential of zero. Energy saving with higher-efficiency centrifugal chillers.

2. Consistent Down-Sizing and High Efficiency

• High-pressure HFC134a refrigerant enables downsizing and weight reduction of the rotating body components in comparison with the conventional low-pressure CFC11 or HCFC123 refrigerant types. Consequently, the energy loss caused by rotation can be reduced for consistent downsizing and high efficiency to be achived.

3. Energy Saving Run Throughout The Year

• Hitachi's unique capacity control mechanism allows energy-saving run throughout the year by stable capacity control in a wide range.
