Amen01 HP476 Chiller and Pumps.pdf

This document is a technical schematic and specification sheet for building mechanical systems, specifically depicting a piping control schematic for domestic hot water distribution and related HVAC equipment selection and scheduling data.

The schematic illustrates a domestic hot water system with components including a domestic hot water heater (PHE-1), vacuum breaker, target trap, and various piping configurations with noted differential pressures and flow rates. A pre-heat exchanger table indicates PHE-1 specifications with a marked temperature setpoint of 200°F and a minimum coil length of 125°F. The air-cooled chiller selection table presents two unit options (ACC-1 and ACC-2) with specifications including minimum total capacity (ranging from 11R to 11R tons), entering and leaving water temperatures (54°F), water flow rates (192 GPM), ambient air temperatures (85-95°F), and voltage/phase/hertz ratings (460/3/60). The exhaust fan schedule provides data for two units (EF-6 and EF-1) with airflow rates of 240-120 CFM, static pressures of .125 inches of water, locations in lounge and January closet areas, motor horsepower ratings (25-35 HP), and identical voltage specifications (120/1/60). The pump schedule details eight pump units (P-1 through P-8) with service types including chilled water, heating water, and domestic hot water applications, water flow rates ranging from 65-384 GPM, total head values from 20-3500 feet, motor horsepower from 1.5-5 HP, and NEMA starter sizing specifications.
