Characteristics of Units

Carrier 30HXY/HXC Screw Chiller has no Chloride (no consumption to ozonosphere), and is efficient (consume less power, making contribution to reduce greenhouse effect), stable, easy to maintain, and low operation cost, which is the first choice of central air conditioning system for hotel, restaurant, office, school, hospital and industrial and mining establishments.

Structural Characteristics of Units

1.	Powerful Pro-Dialog control system, direct-viewing display, and simple operation

2.	Full-liquid evaporator with reinforced heat-transfer pipes, featuring high heat transfer efficiency

3.	Electronic expansion valve is agilely controllable.

4.	Stop valve equipped with refrigerants is easy for maintenance.

5.	External second-stage oil separator conceal installed inside evaporator by Carrier’s patent technology has high efficiency of separation

6.	When releasing from factory, evaporator and condenser are fitted with connection pipes and clamps, which are easy for installation.

Characteristics of Compressor

1.	The compressor can be repaired on-site and Carrier designs dual-screw compressor for HFC-134a

2.	Semi-closed motor is parallel with compressor, which gears up the system, so that compact structure can be realized.

3.	Use aerospace gear AGMA12 (the highest grade of American Gear Manufacturer's Association), which runs quietly and is sturdy and durable.

4.	Employing computer optimization design to produce completely ne w concept tooth of rotor, machining precision of major components can reach micro-size, as a result, compressor is efficient and leakage rate is tiny.

5.	Use refrigerants to cool motor, and motor can work reliably under low temperature.

6.	Plunger type unloading device, simple and reliable structure, no internal loss

7.	Unique design internal silencer reduces gas pulsation of exhaust gas efficiently

Simple and Easy Installation

l	Compact structure, less space demand, save machine room’s space

l	The maximum width of units is only 1015mm, which can easily pass through door frame

l	Whole set of units releases from factory, and the cooling medium has been filled inside

l	When installing, only need connect water pipe and power supply of evaporator and condenser

Low Operation and Maintenance Cost

l	The unit is driven by several sets of compressor, wide adjustment scope of refrigerating capacity, high efficient partial loading

l	The units adopts double-loop design, stable and low maintenance cost

Low Noise (Three-stage noise elimination)

Internal silencer: rational stream guidance of exhaust air, efficiently reduce noise caused by gas pulsation of high pressure exhaust gas

Silencer of gas exhaust pipeline: transform part of sound energy into heat energy, reducing the noise of units

Mute chassis: addition of another noise barrier, significantly reduce noise’s transfer to the machine room

(Refer to the following pictures)

Microcomputer control system has user-friendly interface and clear flow chart display, which is easy to instruct and operate by powerful diagnosis, security protection and communication functions. It employs PID control to keep stable water temperature from evaporator, effectively keep the units in operation and its stability and economy efficiency.

Advanced Control Function

l	Provide local, remote and CCN network to control units start or stop.

l	Advanced EXV electronic expansion valve is driven by 1500-stage stepper motor, which matches screw compressor and full-liquid evaporator, ensuring stable and efficient operation under full or partial loading.

l	Automatically control each refrigeration loops, and start stop of each compressor in each loop, as well as up/down load, in order to balance the operation time of each loop and compressor.

l	Realize interlock control between units and cold water and chilled water to assure units run under efficient and secure conditions.

l	Provide “requirement limitation” function that limits the maximum refrigerating capacity of units through power control. The function can be used for energy management of multi-units, realizing the optimization of whole system operation efficiency by limiting the cold amount of individual unit.

l	When unit starts up, it will reduce flow rate to control water temperature within adjustable scope (0.1-1.1/min), in order to avoid energy loss caused by low temperature water. It will promote energy efficiency ratio of unit, prolong unit’s lifetime.

It offers “Energy save Restoration” function, which will settle a negative correction of cold capacity in accordance with variation tendency of outdoor temperature or return water temperature (provide users with temperature signals), so that unnecessary energy waste can avoid. And it immediately matches the external reducing fluctuation tendency to raise the operation efficiency of units.

Strong diagnosis function

l	Before starting up the unit, the function will quickly confirm every switch, sensor, voltage and compressor by analog inspection.

l	During its operation, human-computer interface will display a variety of setting points and real operation parameters, monitoring units’ operation. When it is necessary, the system will alarm.

l	The unit may provide more than 140 display and alarm information. The operator can resort to relevant solution to remove faults by alarm information.

Complete Security Protection Function

l	The system provides functions such as temperature of cold water is too low, oil pressure is low, pressure of refrigerating fluid is too high, leak current, motor overload, voltage too high or too low, open-phase protection and many others.

Advanced Group Control Function

Every set of unit can provide RS485 Standard serial interface, with which can realize group control to multiple-units, if through CNN network (need phase). The system can connect with the counterparts of other buildings; the standard protocol includes BACnet/Modbus/Lonwork.

Note:

1.	Work condition of air conditioner: cold water in/out temperature is 7/12°C, chilled water in/out temperature 30/35°C

2.	Work condition of ice storage: cold water outlet temperature is -6°C, chilled water inlet temperature is 30°C.

3.	refrigerating medium shall be 25%

Option Explanation

l	Interfaces of water room of evaporator and condenser can reverse respectively

Interface of water room of standard unit is on the right side (control cabinet is front side), the option offers left side interface.

l	Water room of evaporator and condenser can provide 1.6Mpa/2.1Mpa high bearing pressure options

l	Low temperature unit:

Temperature scope of low temperature ethylene glycol and salting liquid:-6°C~+4°C

Can provide minimum -10°C low temperature option, meeting technological demand

l	Mute Chassis

First generation mute chassis can denoise the unit over 10dB(A), easy for installation, no effect to maintenance and management of unit, handsome appearance (please see P2)
