Key Findings

  • 01The cooling system successfully achieved and maintained temperatures down to -5°C, suitable for fresh seafood storage.
  • 02The integrated solar and PLN energy system with ATS functioned correctly, switching power sources based on battery charge levels.
  • 03The system failed to achieve the target humidity range (90%-95% RH), with average relative humidity measuring only 50%.
02

Application

Design takeaway

When designing refrigerated display units for moisture-sensitive products, ensure active humidity control is integrated alongside temperature regulation and energy management.

How to apply

When designing any refrigerated storage or display unit for food products, conduct a thorough analysis of both temperature and humidity requirements and implement appropriate control systems for both.

Project actions

  • 01When designing a product that needs to maintain specific environmental conditions, consider all relevant parameters, not just the most obvious ones (like temperature).
  • 02Think about how different environmental factors interact with each other and how controlling one might affect another.
03

Method & Evidence

AimTo design and test a display cabinet cooling system integrating solar and grid power for fresh seafood, evaluating its performance against established temperature and humidity standards.
MethodCommissioning test
ProcedureA display cabinet cooling system was designed and built, integrating solar and PLN electricity with an Automatic Transfer Switch (ATS). The system's ability to maintain a target temperature of -5°C and a humidity range of 90%-95% for fresh seafood was tested. Performance data was collected through commissioning tests.
ContextFood service industry (restaurants, cafes), specifically for displaying fresh seafood.

Variables

IVIntegration of solar and PLN energy, Automatic Transfer Switch (ATS) control.
DVTemperature achieved (-5°C target), Relative Humidity achieved (90%-95% RH target), System performance (ATS switching).
CVType of seafood displayed, ambient environmental conditions (assumed constant during testing).
04

Strengths & Limitations

Strengths

  • +Successful integration of renewable energy with grid power.
  • +Effective temperature control for seafood preservation.

Limitations

The reliance on opening the cooler door for humidity control is a significant practical limitation that would impact real-world usability and efficiency.

Reliability & validity

The study's validity is supported by the commissioning test method, which is standard for evaluating system performance. Reliability could be enhanced by repeating tests under varied conditions or with multiple units.

Think critically

How might the reliance on opening the cooler door to increase humidity have also negatively impacted the temperature control and energy efficiency of the display cabinet?

05

Design Principles

"Optimal preservation of perishable goods requires simultaneous control of temperature and humidity."

This research highlights the critical balance between temperature and humidity for optimal food preservation. Designers must consider both factors to prevent product degradation, even when employing energy-efficient solutions.

06

What This Means for Your Design

This study shows that while a new fridge for seafood kept it cold, it also made the fish dry because it didn't have a good way to control how humid the air was inside.

How to use in your project

  • 1.Use this research to justify the importance of controlling humidity in your design project, especially if you are designing a food storage or display system.
  • 2.Cite this study when discussing the limitations of your own design or when explaining why you chose to include specific features to manage humidity.

Paragraph starter

This research by Santosa et al. (2021) demonstrates that while achieving target temperatures for seafood preservation is feasible with integrated energy systems, maintaining optimal humidity levels (90%-95% RH) is crucial and often requires dedicated humidification systems, as their study found that insufficient humidity led to product surface drying.
