New Series！This series of HITACHI air-cooled water chillers up to 400HP has been developed for various

requirements of air-conditioning systems and industrial chilled water systems, where these equipment are operated under high

ambient temperatures of 43 ℃,Therefore, the units can be utilized under a wide temperature range.

These water chillers are equipped with newly model-changed semi-hermetic HITACHI A-type screw compressors,

featuring high reliability, low noise and low vibration, and highly efficient air-cooled condenser, resulting in compact design.

The unit is composed of compressors, air-cooled condensers, shell-tube type water coolers, and other auxiliary and control

devices, compactly packaged in a weather-proof cabinet which is constructed of galvanized steel plates processed with

specially baked resin paint.

NEW HITACHI AIR-COOLED WATER CHILLERS… THAT’S THE ACHIEVEMENT OF TOTAL HITACHI TECHNOLOGE… ● The most reliable semi-hermetic screw type compressor Adopting new profile screw rotors, HITACHI have developed the higher performance screw type compressor to obtain a higher reliability and durability of the unit operation.

●Highly Efficiency Operation The appropriate combination of the air side heat exchangers with high performance SLIT fins, highly efficient screw compressors and water side heat exchangers has achieved this high efficiency of operation.

●Smaller Vibration and Lower Operation Sound Due to the combination of the HITACHI semi-hermetic screw compressors and smooth-air-flow propeller fans for air side heat exchangers, smaller vibration and lower sound operation has been achieved, therefore, in most cases, special vibration absorbing curbs are not required by utilizing factory-supplied rubber mats.

In this new century when people pay more attention to the change of the environment, HITACHI semi-hermetic screw type compressors ,which use the R407C refrigerant directly, and reduce the refrigerant leak greatly, have been sold 140,000 in the world !

1. Efficiency is improved by using the highly precision rotors. 2. Separation efficiency is enhanced greatly by changing the oil separation mode.

１．Improve the air heat exchanger configuration. ２．Adopt high heat exchange efficiency inner thread tube 3．Improve air velocity

distribution to enhance efficiency .

Air side heat-exchanger using the converse

M-type distributing resulting in an equality

distribution of the air velocity, achieves highly

heat exchange efficiency.

Capacity Control

Continuous Capacity Control Chilled water outlet temperature can be controlled precisely within ±0.5 of the setting ℃

temperature. This control is performed by applying a micro-computer to the continuous capacity control type screw compressor.

This precise temperature control is not only suitable for air conditioning, but also for industrial use.

-Principle of Continuous Capacity Control- Continuous capacity control is performed by adjusting the slide valve position as shown below. The slide position can be changed freely between 100% and 15% in accordance with cooling load.

NOTE: The flow rate of each model is not different; please refer to the chilled water flow rate on the pages 11 to 16.

Selection Example Determination the System Requirements: Condenser Air Inlet Temperature: 40℃ Chilled Water Outlet Temperature 7℃ Chilled Water Inlet Temperature 12℃ Cooling Load 453kW Power Source Frequency: 50Hz From the cooling capacity table, model RCU180AHYZ1 can be selected with the following performance: Cooling Capacity: 507.5kW Chilled Water Flow Rate: 87.3m3/h Water Cooler Pressure Drop: 69.7kPa Compressor Input Power: 173.2kW The water flow rate in the cooling capacity table is based on the 5 ℃ temperature difference between the chilled water inlet and outlet temperature, if the temperature difference is not 5 ℃ , correct the water flow rater of the water cooler utilizing follow formulas.

Corrected Flow = ×

Rate

The corrected chilled water flow rate must be confirmed to be within the working range described on pages 20

Refrigerant System

In addition to the basic air-cooled water chiller components (compressor, condenser, thermal expansion valves and water cooler), the following components are equipped in each refrigerant cycle: Stop Valve for Compressor Discharge Line and Liquid Line: These stop valves are equipped at the liquid line, and facilitate easy compressor service without appreciable

leakage of refrigerant.

Capacity Control All models are equipped with an unloading system for each compressor, in order to adjust the cooling capacity and provide precise temperature control for the chilled water, coupled with electric thermostat.

Electric Operation Control Electrical Operation Control advanced HITACHI Water Chillers are as follows. Control Panel ON switch, OFF switch, Power Supply Lamp, Operation Lamp, Alarm Lamp, Operation/Alarm Indicator for each refrigerant cycle and check switch are mounted in the Control Panel. The Control Panel is located at a position where easy access is available. Operation/Alarm indicator can display individual alarm codes such as High-Cut, Low-Cut etc. This function is very useful for detecting what alarm has occurred. Check switches are for checking chilled water temperature and alarm occurrence data. Chilled water temperature setting switches, ON/OFF Differential Setting Switches, Remote-Local Switch and so on are located at the rear side of Control Panel, in order not to access during operation. Operation Hour Meter This hour-meter indicates the sum of the compressor operation. Screw Compressor Cycling Protection Circuit The electric timer of the screw compressor cycling protection (CCP ) connected in the compressor control circuit delays the screw compressor restarting period for approximately three (3) minutes for No.1 compressor, four (4) minutes for No.2 compressor, five (5) minutes for No.3 compressor and six (6) minutes for No.4 compressor after the electronic thermostat calls for the cooling operation or automatic resetting of the protection devices, thereby preventing harmful screw compressor cycling operation. Electronic Thermostat Circuit The electronic thermostat senses chilled water temperatures at the water cooler outlet, and operates solenoid valves for HITACHI screw compressor capacity control. Screw Compressor Reversing Protection Circuit This circuit is composed of a reverse-phase protection devices, preventing reverse operation of the screw compressor, because the screw compressor definitely cannot be operated in the wrong direction as the misconnection of the main power phases. Rotation of Compressor Operation Rotation of compressor operation order is available in order to balance operation hours of compressors. This function extends machine life. Restart after Short Period Power-Failure In the case that a power failure shorter than 2 seconds occurred, compressors can be restarted automatically within 3 minutes after power supply.

Note: for the details of the blank places, please contact HITACHI or Hitachi’s distributors. Protection and Safety Control The safety and protective devices are equipped in the unit to ensure dependable and long life operation. Their functions should be carefully noted, and field adjustment is not recommended, if the setting is maintained at the point listed in the table. Compressor Protection

1、The high pressure switch and the low pressure control protect against excessive discharge pressure and

exceedingly low suction pressure. The switch and control cut out compressor operation when the discharge pressure exceeds the setting or when the suction pressure decrease below the setting.

2、Overcurrent relays equipped in the magnetic switch box cut out each compressor operation when the current to the compressor exceeds the setting.

3、The internal thermostat embedded in the compressor motor winding cuts out each operations, when the temperature of the motor winding exceeds the setting.

4、An oil heater in the compressor prevents from oil foaming during cold starting. Energize this heater to warm the oil, while the compressor is stopped.

Fan Motor Protection The thermal overcurrent relays for the condenser fan motors cut out fan operation and compressor operation, when the current to the fan motor exceeds the setting. Refrigerant Cycle 1、The fusible plug is equipped on the liquid line. When refrigerant temperature exceeds the melting point,

and the plug melts and purges the refrigerant gas, in order to avoid explosion of the condenser. 2、The freeze protection control, for which the sensor is located in the water outlet near the water cooler, cuts

out the compressor operation, when the water outlet temperature decreases below the setting.
