The HITACHI H series water-cooled water chillers are designed for all the conveniences of chilled water air-conditioning systems, especially for hotels, stores, hospitals、modern building and process cooling applications of modern manufacturing industries. HITACHI water-cooled water chillers are equipped with newly-developed HITACHI A type semi-hermetic screw compressors, which feature higher precision and simplicity of construction by eliminating such items as pistons, connecting

rods, valve plates, oil pumps and mechanical linkages for capacity controls in the reciprocating compressors. These features result in lower noise and lower vibration, reliable long period operation, and installation feasibility on any floor of the building. The units are composed of a compressor(s), a condenser(s),a direct-expansion water cooler, a electronic expansion valve(s),and auxiliary and control equipment. The units can be operated with the utmost simplicity.

Easy for Maintenance Equipped with accessibility components such as Pressure Relief

Valve and Oil Sight Glass, easy maintenance is obtained.

Factory-Charged The refrigeration cycle is charged with refrigerant and sealed under the strict quality control, therefore installation and operation can be performed in a short period of time. Factory-Wires Only power wiring and water piping are required in the field. Most Reliable Protective and Ancillary Components The units are protected against any assumed failure of operation, based on the following components: Electronic Timer for Compressors, Three-Phase Quick Response Overcurrent Relay, Internal Thermostats for Compressor Motors, Freeze Protection Thermistors. Pressure Relief Valve, Oil Sight Glass, Oil Heater and Reverse-Phase Protection Relays for Compressors. Hour Meter This device indicates the operation hours of the screw compressor; therefore, accurate maintenance time can be checked with this hour meter.

Hitachi’s Semi-Hermetic Screw CompressorThe newly-developed HITACHI semi-hermetic screw compressors feature long life and quiet operation due to simplicity of construction when compared with the conventional reciprocating compressors. A Symmetrical Rotor Profile and Other Features. This profile of the compressor rotor, five-six (male and female) type, assures excellent efficiency even in high compression ranges, in addition to these uniquely-profile rotors, the following features are incorporated.

Use of special bearing, resulting in long life and high reliability Patented capacity control system, enabling simple control

system. High precision and high-grade finishing rotors, enabling no

oil-cooling system. Automatic Capacity Control An Automatic capacity control mechanism enables the unit to perform economical and energy-saving operation depending on various conditions. Additionally, two(2) independent refrigeration cycles are provided for model RCU(G)80WHYZ(-E)、RCU(G)100WHYZ(-E)、RCU(G)120WHYZ(-E)、RCU(G)220WHYZ(-E)、RCU(G)260WHYZ(-E)、RCU(G)300WHYZ(-E) 、RCU(G)340WHYZ(-E)、and RCU(G)380WHYZ(-E)； Three(3) independent refrigeration cycles are provided for model RCU(G)150WHYZ(-E)、RCU(G)180WHYZ(-E)、RCU(G)410WHYZ(-E)、RCU(G)450WHYZ(-E) 、RCU(G)490WHYZ(-E)and RCU(G)530WHYZ(-E)、RCU(G)570WHYZ(-E) to avoid complete shutdown and ensure 50% of capacity provided at the less even in maintenance.

The following accessories are supplied with the unit: 1. Vibration-Proof Rubber Mats 2. Foundation Bolts

The combination of these mats and bolts effectively minimizes noise and vibration, and is coupled with facilitated installation procedures.

The following accessories are optional: 1. Communication adapter connecting the unit to BMS (Building Management System) is an optional accessory . ( LONWORKS or

RS485 option) 2. Big colorful liquid crystal screen display.( both English and Chinese can be supplied). Please get in touch with HITACHI or HITACHI distributor if required .

1.Determination the System Requirements.

Calculate the total Load under design conditions. Given conditions: Power Source Frequency 50Hz Cooling Load 420kW (361,200kcal/h) Condenser Water Inlet Temperature 30℃ Condenser Water Outlet Temperature 35℃ Chilled Water Inlet Temperature 12℃ Chilled Water Outlet Temperature 7℃ Fouling Factor of Water Cooler 0.018m2.℃/kW Fouling Factor of Condenser 0.044m2. ℃/kW

2.Select a Matching Model and Read Performance of the Unit

Select unit model RCU120WHYZ(-E) ,according to the conditions mentioned above :condenser water outlet temperature (CDOT) of 35℃ and chilled water outlet temperature (CLOT) of 7℃.

3.Read the Unit Performance of the Model.

The compressor Input (IPT), cooling capacity (CCAP),Chilled water flow rate (CFR), condenser flow rate (HFR) can directly be determined from the table and the figure. In the case where the data cannot directly be determined from the table, the data can be determined by interpolation. Compressor Input (IPT) 82.5kW Cooling Capacity(CCAP)

425kW (365,500 kcal/h) Chilled Water Flow Rate (CFR) 73.1m3/h Cooled Water Flow Rate (HFR) 87.3 m3/h Condenser Heat Discharge.(HCAP) 508 kW Cooler Pressure Drop (CPD) 87 kPa Condenser Pressure Drop (HPD) 48 kPa

4.Correct the Data

Flow Rate When the water temperature difference of condenser or water cooler is different from 5℃, please correct the water flow rater of condenser or water cooler by following formulas.

Corrected Flow = × Rate

or

Corrected Flow= × Rate

Cooling Capacity and Compressor Input When fouling factors are different from 0.018m2. ℃/kW(cooler) and 0.44 m2.℃/kW(condenser) ,the cooling capacity and compressor input will also be different from the value indicated in the cooling capacity table.

SELECTION DATA



CCAP: Cooling Capacity (kW) CPD: Cooler Pressure Drop (kPa) HPD: Condenser Pressure Drop (kPa) Note: 1 The chilled water flow rate and the condenser water flow rate are based on 5℃ of temperature difference between the outlet and inlet of the water cooler or the condenser. 2 The data circled by lines at 35℃ of CDOT and 7℃ of CLOT are based on the condition indicated in the “General Data”

SOUND DATA

Note： 1、 The above uses (SPL-A) A scale sound pressure level data （dB）。

2、 The measuring point is 1.0 meter from the center of the machine surface and 1.5 meter from the floor level。

3、 The units are operating under a standard working conditions。

4、 The sound data are measured on the flat, so the influence of the resonance should be considered while the unit

is located in a rounding wall.

1、Pump Operation Control 2、Pump and Cooling Tower Interlock Notes: 1.Select A or B for the desired operation method and perform the wiring according to the above wiring diagram.

A : for build-in operation switch B: for remote push button switch.

2. In case of applying the remote indication as shown in the above figure, shielded wires shall be used in order to avoid misguiding .

3.The maximum current value for contactor ”APp1”shall be lower than 5 A.

Tool and Instruments—One Set of Wiring Tools and Electrical Tester (Clamp Meter) Schedule Check--Confirm that the field-selected electrical components (main power switch, fuses, wires, conduit connections and wire terminals) are properly selected according to the “Electrical Data” in Technical Catalog I and ensure that they comply with national and local codes. It is recommended that the main power switch be locked on the “OFF” position, to prevent against accidental supply of power during unit servicing.

Main Power Wiring Procedures— Confirm that electrical power is not being supplied to the installation location prior to any electrical installation work.

1.Install the field-supplied main switch box in the properly selected location.

2. Install conduit connectors in the hole for power wiring.3. Lead main power wires and earthing wire through

connector to the screw terminals for main power and earthing in the electrical box. The neutral wire for 380v and 415V power supplies should also be led through the connector.

4. Firmly connect the wires with wire terminals to unit screw terminals T,S and T(and also Mp for 380V and 415V power supply) according to the following figures.

Control Wiring—Connect the interlock wiring among the unit terminals 、the water pump and the cooling tower starter according to the following figures or the wiring labels.
