ASHRAE 90.1 - 2019

This product meets the minimum efficiency requirements of ASHRAE Standard 90.1 (which are based on AHRI standard rating conditions with water) and, therefore, also meets the LEED "Minimum Energy Performance" prerequisite in the Energy and Atmosphere section.

The LEED Green Building Rating System™, developed by the U.S.

Green Building Council, provides indepenent, third-party verification that a building project meets green building and performance measures.

Foundation Provide rigid, non-warping mounting pads or a concrete foundation of sufficient strength and mass to support the applicable operating weight (i.e. including completed piping, and full operating charges of refrigerant, oil and water). The expectation of Trane equipment is that piping is fully supported by an independent structure/system, without being connected to the waterbox. Once in place, the unit must be level within 1/2" across the length and width of the unit. The Trane Company is not responsible for equipment problems resulting from an improperly designed or constructed foundation.

Center Of Gravity

Different unit configurations and options may cause a variation in the center of gravity from what is listed in the submittal.. Refer to the Installation, Operating and Maintenance manual for specific lifting instructions.

General Units are constructed of a galvanized steel frame with galvanized steel panels and access doors.

Component surfaces are finished with a powder-coated paint.

Each unit ships with full operating charges of refrigerant and oil.

Compressor and Motor The unit is equipped with four hermetic, direct-drive, 3600 rpm 60 Hz suction gas-cooled scroll compressors. The simple design has only three major moving parts and a completely enclosed compression chamber which leads to increased efficiency. Overload protection is internal to the compressors. The compressor includes: centrifugal oil pump, oil level sight glass and oil charging valve. Each compressor will have compressor heaters installed and properly sized to minimize the amount of liquid refrigerant present in the oil sump during off cycles.

Unit-Mounted Starter The control panel is designed per UL 60335. The starter is in an across-the-line configuration, factory-mounted and fully pre-wired to the compressor motor and control panel. Typically, Trane scroll compressors are up to full speed in one second when started across-the-line.

A factory-installed, factory-wired 820 VA control power transformer provides all unit control power (120 Vac secondary) and Trane Symbio (TM) 800 controller module power (24 Vac secondary).

A molded case standard interrupting capacity circuit breaker, factory pre-wired with terminal block power connections and equipped with a lockable external operator handle, is available to disconnect the chiller from main power.

Power Connection Power connections include main three-phase power and two separate 115V, 20 amp customer provided single phase power connections are required to power the heaters (if used for freeze protection) as well as the programmable relays.

Short circuit current rating of 5 kA is provided.

Evaporator Braze plate evaporator is made of stainless steel with copper as the braze material. It is designed to withstand a refrigerant side working pressure of 430 psig (29.6 bars) and a waterside working pressure of 150 psig (10.5 bars). Evaporator is tested at 1.1 times maximum allowable refrigerant side working pressure and 1.5 times maximum allowable water side working pressure. It has one water pass. A water strainer and a flow switch are factory installed.

Immersion heaters protect the evaporator to an ambient of -20°F (-29°C).

All evaporators have grooved pipe connections.

An additional temperature sensor, at the compressor discharge, enables leaving evaporator water temperature below 42°F (5.5°C).

Note: An additional 115V, 20 amp field provided single phase power connection is required to power the heaters (if used for freeze protection).

Condenser Air-cooled condenser coils have aluminum fins mechanically bonded to internally-finned copper tubes.

Completely assembled coils are then dipped and baked in an electro-mechanically bonded flexible epoxy coating. Coating covers all condenser coil surfaces with uniform coating to protect against corrosion with negligible performance loss. Coil with coating successfully passed 6000+ hour salt spray test.

The condenser coil has an integral sub-cooling circuit. The maximum allowable working pressure of the condenser is 650 psig (44.8 bars). Condensers are factory proof tested at 650 psig (44.8 bars).

Direct-drive vertical discharge condenser fans are balanced and individually protected. Three-phase condenser fan motors with permanently lubricated ball bearings and external thermal overload protection are provided.

A variable speed drive on the first fan of each circuit allows the unit to start and operate with ambient temperatures between 0.0 F and 125.0 F.

Refrigerant Circuits The unit has dual refrigerant circuits. Each refrigerant circuit has Trane scroll compressors piped in parallel with a passive oil management system. A passive oil management system maintains proper oil levels within compressors and has no moving parts. Each refrigerant circuit includes filter drier, electronic expansion valve, liquid line and discharge service valves. Capacity modulation is achieved by turning compressors on and off. The unit has four capacity stages.

Communications BACNet Interface allows the user to easily interface using BACNet MS/TP via a single twisted-pair wiring to a factory-installed and tested communication board.

Programmable Relays Predefined, factory-installed, programmable relays allow the user to select four relay outputs. Available outputs are: Alarm-Latching, Alarm-Auto Reset, General Alarm, Warning, Chiller Limit Mode, Compressor Running, and Tracer Control.

Note: An additional 115V, 20 amp field provided power connection is required to power the programmable relays.

Architectural Louvered Panels Louvered panels cover the complete condensing coil and service area beneath the condenser.

Isolators Molded elastomeric isolators, sized to reduce vibration transmission to the supporting structure when the unit is installed, ship with the chiller.
