Tests at the University of Illinois compared three refrigerators: one with granulated cork insulation and two with mineral wool. The refrigerator with granulated cork had a lower melting rate per hour, making it more economical for general use. Tests by Good Housekeeping Institute on Bohn Syphon refrigerator showed good construction, easy cleaning, and efficient operation. Detailed specifications of the cabinet are provided, including dimensions, storage space, insulation materials, and performance metrics. The chapter also includes tables with test data from different refrigerators and a score card to evaluate various aspects of refrigerators.
Key Takeaways
- Granulated cork insulation is more economical than mineral wool for ice refrigerators.
- The Bohn Syphon refrigerator has a seamless lining that makes it easy to clean and maintain hygiene.
- A score card evaluates various aspects of refrigerators, including temperature control, ice economy, humidity, circulation, interior finish, drainage, exterior finish.
Practical Tips
- Choose refrigerators with granulated cork insulation for better efficiency and cost-effectiveness.
- Ensure your refrigerator has a seamless lining to facilitate easy cleaning and hygiene maintenance.
- Use the provided score card to evaluate different types of refrigerators based on their performance metrics.
Warnings & Risks
- Do not open the refrigerator door frequently during testing as it can affect temperature readings.
- Be cautious when handling ice, especially in large quantities, due to potential injuries from sharp edges or heavy lifting.
Modern Application
While this chapter focuses on historical ice refrigerators, its principles of efficiency and cost-effectiveness remain relevant today. Modern refrigeration technology has improved insulation materials and energy consumption, but understanding the basics of refrigerator testing can still help in making informed decisions about appliance purchases.
