<br />Exhibit A1, A2, & A6 5-8-23 <br /> <br />2 <br />i. Controls: <br />i. Custom ammonia chiller: Beyond Cool™ rink control system <br />j. Warrantees: <br />i. Custom chiller: Compressors & Pumps 2 years, Vessels 5 years <br />k. The max Delta-T for supply and return temps across the ice rink floor will be 3ᵒF or less: <br />This cannot be achieved with a commercial refrigeration system. <br />9. Waste Heat Reclaim and Supplementals Heating System: This has to be discussed further <br />a. Total capacity: xxx MBH <br />b. Subfloor Systems 1 ice sheet <br />c. Supplemental heat: For Snow-melt and resurfacer room <br />d. Snow-Melt One ice cut per floor, per hour 2 Sheets <br />e. Zamboni Fill Station Capacity 1 ice sheet <br />f. Zamboni Deicing 1 cut per hour <br /> <br />All Design and Engineering including stamped drawings to be used for permitting. <br /> <br />Total Cost of Exhibit A1: Design & Engineering: $82,577.00 <br />Total Cost of Materials Procurement through Sourcewell: $0.00 <br />Total Ice Box Commitment: $82,577.00 <br /> <br />Exhibit A2 – Chiller Specifications <br />CHILLER DESIGN AND ENGINEERING <br />1. The refrigeration system will be factory built on a frame (skid) for transportation. The ice rink <br />subcontractor designs the skid with serviceability in mind. <br />2. All motors must be easily accessible for repair and replacement, i.e.: compressor motors will <br />not be positioned under any vessels. <br />3. Control system to have the control (Low voltage section) isolated from the power (high voltage <br />460/3/60) with a physical barrier. <br />4. Mechanical contractor shall include: <br />a. All primary and secondary refrigerants <br />b. All refrigerant oil <br />c. Initial motor lubrication <br />5. The ice rink subcontractor will provide engineered stamped drawings for their approved <br />complete refrigeration system: chiller, floors, snowmelt. <br /> <br /> <br />
