chiller startup sequence

Miscellaneous Monitoring Points 9. When power is supplied to the chiller control panel and the chiller is not in operation, the Stop light (RL) is on. The extensive Trane chiller product line was developed based on decades of knowledge and industry leadership, and includes centrifugal, helical-rotary and scroll compressor chillers, ranging in capacities from 20 to 4,000+ tons. Cluster startup and shutdown sequence :-Startup sequence :-Start the cluster in Node 1. Interested in this topic? When operating this equipment, use good judgment and safety precautions to avoid damage to equipment and property or injury to personnel. Condensing Units. Although city water may be acceptable initially, it is almost never recommended that de-ionized water be maintained for the long term as it could have adverse affects on certain metals in the chiller. The hard drive is like RAM, but it is non-volatile and slower. 21 Primary-only System Staging 500 GPM 500 GPM 0 GPM. Ideal for comfort and process cooling, glycol chilling, heat recovery and heat pump applications; Heat pump to 150°F (66°C) Uses R-134a refrigerant; YK Centrifugal Chiller. Start the cluster in Node 2. Sequence of installation for water chiller. Use only distilled, de‐ionized, reverse‐osmosis (RO), or de‐mineralized water in the chiller. 5.1.5 Ensure evaporator and condenser water pressure is 1 to 3 kg/ Cm². 5.1.8 Maintain log sheet of chiller. Extra water/glycol should be on hand during the startup to top‐off the reservoir as needed. The chiller costs less to purchase and install than other chillers in its class, and operates quietly and efficiently. 10 and 14) 1. Check that pressure and temperature gauges (and flow meter if any) are properly installed. Shutdown the cluster in Node 2 This is the final stage in the boot process, after which the user can access the system’s applications to perform tasks. Air-cooled Chillers. Preparation Before starting the chiller, verify: Power is on to the main starter, oil pump relay, tower fan starter, oil heater relay, and the chiller control panel. Brochure * Entries are ordered by date. Once the startup sequence is complete, the BIOS does very little as your computer’s operating system takes control. INITIAL START-UP IMPORTANT: Startup engineer is to be properly certified for the starter/VFD.

Cooling tower water is at proper level and at-or-below design entering temperature. Prior to moving the chillers at site, ensure that the foundation requirements have been done. Yes No If there is any shipping damage, please list all damage in detail: Crankcase heaters are verified operational and have been on continuously for at least 12 hours? Water-cooled chillers within the scope of the AHRI WCCL certification program are certified in accordance with the AHRI Water-Cooled Water-Chilling and Heat Pump Water-Heating Packages Certification Program, which is based on AHRI Standard 550/590 (I-P) and AHRI Standard 551/591 (SI). With a vast arsenal of tools and configurations, we have the knowledge and brainpower to tackle even the most sophisticated cooling needs. Heat Pump Loops & Towers 7. The second lag chiller will start under the same conditions and sequences. CHILLER SYSTEM START-UP SHEET CHILLER MODEL #: CHILLER SERIAL #: CUSTOMER : START-UP DATE : PRE START-UP CHECK LIST All Electrical Connections are tight, these may loosen during shipment Main Disconnect Energized for 24Hr. RE: chiller plant operation sequence TEGGER (Mechanical) 2 Sep 03 23:07. Check the control panel to ensure it is free of foreign material (wires, metal chips, tools, documents, etc.). Whenever a lag chiller starts, all running chillers load and unload as necessary to be running within 5 percent of the same percent load (based on rated current).
