New Series！HITACHI H Series air-cooled water chillers which achieve to 400HP, are designed for all the conveniences of chilled water air-conditioning systems and modern manufacturing industries，these chillers can operate normally even at 43 of the outdoor air temperature，that is why the chillers can apply for larger temperature range。 HITACHI air-cooled water chillers are equipped with newly-developed HITACHI A type semi-hermetic screw compressors which features are lower noise and vibration, reliable long period operation and used the higher performance air-cooled condenser that result in compact structure。 The units are composed of a compressor(s), a air-cooled condenser(s), a shell-tube type evaporator and auxiliary and control equipment, these parts are equipped in the metal cabinet for avoiding the climate influence，the shell plate is used the galvanize steel with oleoresin paint。

FEATURE

New HITACHI AIR-COOLED WATER CHILLERS… THAT’S THE ACHIEVEMENT OF TOTAL HITACHI TECHNOLOGE… ● Reliable semi-hermetic screw type compressor

Adopting new screw rotor outline , HITACHI have developed the higher performance screw type compressor to improve the operation reliable and durable. In this new century, people pay more attention to the change of the environment… HITACHI semi-hermetic screw type compressor ,which use the R407C directly, reduce the refrigerant leak greatly, and have been sold 140,000 in the world ! Discharge Outlet

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

highly

efficiency heat exchange is achieved, and improve defrost performance.

１．Improve the air heat exchanger configure. ２．Adopt highly efficiency inner thread tube 3．Improve Air velocity distribution to enhance efficiency and defrost performance

●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.

FEATURE

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 Load-up signal When there is a big use. 12sec.

1. These data are based on the same conditions as those for the cooling capacity; please refer to the notes for the Unit General Data. 2. The starting current is indicated for each compressor. 3. The “Maximum Unit Current” is the total running of the unit under the following conditions, which consume the maximum current within the unit working range. Supplied Voltage: Rated Voltage×0.9 Condenser Water Inlet Temperature: 43 Chilled Water Outlet Temperature: 15 Capacity Control: 100% Therefore, the size of wiring and fuses must be determined according to applicable national and local codes. 4. In addition to the conditions mentioned in the item 3, the compressor currents can be estimated as shown below. One-Compressor Maximum Instantaneous

CONTROL SYSTEM

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 compressor discharge line and 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. extends machine life.

This function

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.

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 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. This heater warms 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.
