Energy efficiency in refrigeration systems

Efficient use of energy in refrigeration is critical. This unit demonstrates how capacity requirements are met by connecting several small compressors in parallel, allowing for optimum adaptation by adding or removing compressors as needed.

• refrigeration system in multicompressor operation
• 3 compressors connected in parallel with multicompressor controller
• heat exchanger for refrigerant supercooling
• glycol-water circuit with heater serving as cooling load
• oil separation and return system
• variable speed condenser fan
• software for data acquisition via USB under Windows 11
• refrigerant R513A, GWP: 631
