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.
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.
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.

Air-Cooled Scroll Chiller Technical Sales Guide 13 APPLICATION DATA Unit Location The chillers are designed for outdoor installation. When selecting a site for installation, be guided by the following conditions: 1. For outdoor locations of the unit, select a place having an adequate supply of fresh air for the condenser. 2. Avoid locations beneath windows or between structures where normal operating sounds may be objectionable. 3. Installation sites may be either on a roof, or on the ground. 4.
Cooler Flow Range: Chiller ratings and performance data pertain to cooling temperature rise of 10 ℉ (12.4℃ ). Chillers maybe suitable for operation in a range from 5.4 to 14.5 ℉ (-15~-9.9 ℃ )temperature rise without adjustment, provided flow limits are not exceeded. High flow rate is limited by pressure drop that can be tolerated ( for any high flow rate value larger than values in performance tables, please refer to GREE factory).
