Project Description
The intent of this project is to replace the existing air-cooled chiller at the Moore County Court
Facility with a chiller of similar type and performance. The current chiller was manufactured by
Airstack. It is a three module multi-stack chiller, model number: ASP30A. The existing chiller
was designed with 88.2 tons of capacity, 211 GPM ,54 EWT/ 44 LWT with a 6.3 foot of head
drop across the evaporator. The basis of design for the replacement is a new chiller by Airstack
with 3 modules to match the existing footprint and performance as closely as possible. The basis
of design for the replacement chiller has a performance of 211 GPM, 53.3/44 with a 9.07 foot of
head drop across the evaporator. The proposed chiller shall have a 1.18k kW/ton (95 DB
ambient temp) efficiency at full load and a 0.8162 kW/ton efficiency at 50% (65 DB ambient
temp) capacity. The existing electrical feeder is 460V/3 phase with a 225-amp overcurrent
device. New chiller shall have a 120V 20-amp circuit for freeze protection. Contractor shall
verify the Freeze Protection circuit is on existing chiller and provide a new circuit as necessary.
