Refrigeration chamber and defrosting methods

The climate in the cold storage room has a significant effect on the quality of the products stored there. This climate depends on different influences, such as the surface temperature of the evaporators, cold storage room temperature, degree of evaporator icing, quantity and type of refrigerated goods etc.

• refrigeration system to investigate the climate in the refrigeration chamber and different defrosting methods
• 2 evaporators, separately switchable via solenoid valves
• electric defrost heater
• hot gas defrosting
• defrost timer
• latent and sensitive cooling load
• evaporation pressure and temperature adjustable
• heat exchanger as superheater and for refrigerant supercooling
• digital display for temperature and humidity in the refrigeration chamber
• refrigerant mass flow rate calculated in the software from recorded measured values
• software with online representation of the h-x diagram
• software for data acquisition via USB under Windows 11
• refrigerant R513A, GWP: 631
