Ice Rink Technician Certification Practice Exam Questions And Correct Answers (Verified Answers) Plus Rationales 2026 Q&A | Instant Download Pdf

Covers: Ice Maintenance, Refrigeration, Facility Operations, Safety, and

Equipment

• What is the ideal ice temperature for hockey play?

A. 15°F (-9°C)

B. 22°F (-5.5°C)

C. 28°F (-2°C)

D. 31°F (-0.5°C)

Rationale: Hockey ice is maintained around 22°F to balance hardness and

skate glide performance.

• What is the recommended brine temperature for maintaining quality

ice? 1 / 4

A. 10°F (-12°C)

B. 16°F (-9°C)

C. 20°F (-7°C)

D. 25°F (-4°C)

Rationale: Brine at 16°F keeps ice stable without overloading the

refrigeration system.

3. The most common refrigerant used in indirect ice rink systems is:

A. R-22

B. CO₂

• Ammonia (NH₃)
• Propane

Rationale: Ammonia is efficient and widely used in large indirect systems

for rinks.

• What is the purpose of the ice resurfacer’s wash water system?
• To melt snow buildup
• To remove dirt and debris before applying hot water
• To cool the ice surface
• To prevent melting

Rationale: The wash system cleans the surface to ensure smooth bonding

of new ice layers. 2 / 4

• What type of glycol is commonly used as secondary refrigerant in rinks?
• Ethylene glycol
• Propylene glycol
• Methanol
• Calcium chloride

Rationale: Propylene glycol is safer and less toxic for public environments.

• What is the typical ice thickness for hockey?
• ½ inch (1.25 cm)
• 1 inch (2.5 cm)
• 1½ inches (3.8 cm)
• 2 inches (5 cm)

Rationale: 1 inch is optimal for performance and energy efficiency.

• What is the main function of the refrigeration compressor?
• To raise refrigerant pressure and temperature
• To lower refrigerant pressure
• To remove air from the system
• To circulate brine

Rationale: Compressors increase refrigerant pressure for heat rejection in

the condenser. 3 / 4

• When painting ice white, what is the purpose of the white base coat?
• Aesthetic only
• Reflect light and improve visibility
• To cool the surface
• To thicken ice faster

Rationale: White paint reflects light, enhancing visibility and energy

efficiency.

• What component removes heat from the refrigerant gas?
• Evaporator
• Condenser
• Compressor
• Expansion valve

Rationale: The condenser rejects heat absorbed in the evaporator to the

environment.

10. The expansion valve in a refrigeration system controls:

• Compressor operation
• Flow and pressure of refrigerant into evaporator
• Ice temperature
• Cooling tower speed
