3.1 Brief Introduction

The units with multi refrigerant circuits from to 152 kW have outstanding benefits that make this product effective for a variety of applications. The units are shipped from the factory completely ready for installation and use. Each unit is pressure-tested, evacuated, and fully charged with R410A, and has an initial oil charge. After assembly, a complete operation test is performed with water flowing through the cooler to assure that the refrigeration circuit operates correctly.

The units can be installed on the rooftop, ground outside and so on instead of being equipped within a special machine room. It can be widely applied in new built or reconstructed industry and civil-building project, such as hotel, apartment, restaurant, office building, shopping mall, theater, gymnasium, hospital and so on, as well as supplies required cooling water for factories in technical process of producing, so it's especially suitable for some special locations around where there are high-level requirements for noise and environments and cooling tower are difficult to install.

3.2 Standard Specifications

High Efficiency Full Load Operation

Utilizing new scroll compressor technology, the chillers meet or exceed the performance requirements of ASHRAE 90.1. All system components are selected for optimum performance, including the condenser coil areas and evaporator sizes.

Excellent Part Load Performance

By using multi compressors on each chiller, unloading characteristics and part load performance are outstanding. Integrated part load value (IPLV) is a part load performance indicator as outlined in ARI Standard 550/590-1998. The IPLV rating compares the performance of different chillers under identical conditions. When the IPLV is listed in EER (Energy Efficiency Ratio), a higher EER will indicate that the chiller's overall performance is better.

Compact Design with Small Footprint

The chillers have a reputation for a compact design and small footprint. A small footprint can save installation costs by minimizing the size of the concrete mounting pad or reduces the amount of structural steel if the unit is mounted on the rooftop.

Quiet Operation

The chillers are designed with quiet scroll compressors. Fans are selected for good performance and lower sound levels. The attention to detail with sound is critical in the design. Small issues such as refrigerant piping, supports for piping, securing components to the structure are all important to making a quiet product. We proudly publish our sound performance.

Superior Controls

GREE has provided the latest technology in controlling the chillers. The new controller provides a“user friendly”environment for the operator. The control logic is designed to provide maximum efficiency, to help provide continuing operation in unusual operating conditions through proactive controls, and to provide a history of conditions to aid in problem resolutions. Perhaps the greatest benefit is the Protocol for integrating with your building automation system (BAS).

Compressors

These rugged hermetic compressors are constructed with an integral cast iron frame, cast iron scrolls, three Teflon impregnated bearings, and three oil filtration devices for each compressor. One to thity-two compressors can run, depending on the load of the system, resulting in excellent Part-load efficiency. Each refrigerant circuit has specially designed oil and gas equalization lines to control oil migration.

The design also offers radial and axial compliance, a large internal volume for liquid handling, a removable suction screen, and a rotary dirt trap and oil screen. In addition, the compressor is self-compensating for wear, handles moderate liquid slugging, and inherently yields high efficiency.

Air-Cooled Scroll Chiller Technical Sales Guide

This well protected compressor includes a solid-state motor protection module, 4 individual motor winding sensors, a patented internal discharge temperature probe, and a patented shutdown feature that prevents reverse rotation. An internal discharge check valve helps prevent shutdown noise and comes standard with high and low pressure taps with Schrader valves, a sight glass, an oil level adjustment valve, and an off cycle crankcase heater.

Evaporator

The evaporator is direct expansion, shell-and-tube type with water flowing in the baffled shell side and refrigerant flowing through the tubes. Two independent refrigerant circuits within the evaporator serve the module's dual refrigerant circuits. The evaporator has a carbon steel shell and seamless high efficiency copper tubes roller expanded into a carbon steel tube sheet. Refrigerant heads are carbon steel with multi-pass baffles to provide oil return . For water removal, 10mm vent and drain plugs are provided on the top and bottom of the shell. An ambient air thermostat controls the heater cable. The fitted and glued in place insulation has a K factor of

0.28. The refrigerant side maximum working pressure is 4400 kPa. The water side working pressure is 1048 kPa. Each evaporator is designed, constructed, inspected, and stamped according to the requirements of the ASME Boiler and Pressure Vessel Code.

Condenser

Cond enser coils have internally enhanced seamless copper tubes arranged i n a stag gered row pattern. The coils are mechanically expanded into flat aluminum fins with full fin collars. A variety of optional coil ma terial and coatings are avai lable for corrosive atmospheres. Fans -The condenser fans are co mposed of corrosion resistant aluminum hub and glass-fiber-reinfo rced polypropylene composite blades molded into a low nois e airfoil section. They are designed for maximum efficiency and are stat ically and dynamically balanced for vibration-free oper ation. They are dire ctly driven by independent motors, and positioned fo r vertical ai r discharge. The fan guards are constructed of heavy-gauge, rust-resistant, c oated steel. Al l blad es are statically and dynamically balan ced for vibration-free ope ration. Motors-The fan motors are totally enclosed air-wver, squirrel-cage type. They feature

ball bearings that are double-sealed and permanently lubricated.

3.3 Standard Accessories

Unit on-off switch: ON-OFF switch is provided for manually switching the unit control circuit.

Indicator lights: LED lights indicate power on to unit, running state and fault indications due to safety devices.

Filter: Refrigeranting circuits are kept free of sludge, acid and oil contamination with it. Under voltage and phase protection: Protects against low incoming voltage as well as

single phase, phase reversal. Liquid line solenoid valve: IT coses when the compressor is off to prevent any liquid

refrigerant from accumulating in the evaporator.

3.4 Standard Control & Safety Devices

The chiller's Unit Control Module is an innovative, modular microprocessor control design. It coordinates the actions of the chiller in an efficient manner and provides stand-alone operation of the unit. A Human Interface Panel is a standard component of the Chiller. Access to all unit controls is via the Human Interface Panel.

Safety valve: Protects the unit against high discharge pressure. Compressor In-built protection device: Motor winding temperature, discharge gas

temperature and phase reversal for direction of rotation. Crankcase heaters: Protects the unit against refrigerant migration, oil dilution and

potential compressor failure. High pressure switch: Provides protection in case of excessive discharge press-ure. Low pressure switch: Provides protection in case of unsafe low suction pressure.
