The refrigeration brief should state the ice load, operating schedule and recovery target before the equipment is selected.
Describe the ice and the schedule
Start with ice area, sport, target surface temperature, hours of operation, session length, resurfacing frequency and the recovery expected after a full session. A training center, a public rink and a competition arena will not create the same load profile.
Describe the building and the climate
Ambient temperature, humidity, solar exposure, envelope performance, plant-room location, electrical supply, water, drainage and service access all affect the package. The most important number is rarely the only number.
Ask for a serviceable package
Show the assumptions
Ice area, ambient design point, target temperatures, operating hours, peak occupancy and recovery expectations.
Make performance visible
Instrumentation, alarms, setpoints, circuit identification and records that let the operator understand the system.
Plan beyond start-up
Commissioning tests, training, maintenance access, spares and a clear escalation route after opening.
When the brief includes these points, supplier proposals become easier to compare and late changes are easier to price. It also gives the design team a better basis for coordinating the plant room and ice pad.
