Comprehensive Guide to Installing Condensing Units and Evaporators for Efficient PU Sandwich Panel Cooling Storage Rooms

Cold storage facilities are essential for industries such as food and beverage, pharmaceuticals, and chemicals. These facilities ensure temperature-sensitive products are preserved under optimal conditions, minimizing spoilage and maintaining product quality. At the heart of any high-performing cold storage room are three key components: condensing units, evaporators, and PU sandwich panels.

This guide explores the comprehensive process of installing these critical components, highlighting the expertise of PT. BJT Indonesia in delivering efficient cooling storage solutions.

1. Overview of Key Components

Condensing Unit

The condensing unit is the "engine" of the refrigeration system. It removes heat absorbed from inside the cold room, ensuring the desired low temperatures are consistently maintained. Modern condensing units are designed for efficiency, energy savings, and reliability.

Evaporator

The evaporator works in tandem with the condensing unit, absorbing heat from the cold room and converting refrigerant into a gaseous state. It plays a vital role in maintaining even temperature distribution and ensuring optimal cooling performance.

PU Sandwich Panels

Polyurethane (PU) sandwich panels are the structural backbone of a cooling storage room. They provide excellent thermal insulation, preventing external heat from entering and internal cold air from escaping. Their lightweight design, durability, and easy assembly make them ideal for modern cold storage construction.

2. Pre-Installation Preparations

Before starting the installation process, proper planning and preparation are crucial:

A. Site Assessment

  • Evaluate the site for accessibility, structural integrity, and environmental factors.
  • Identify any challenges such as uneven ground, limited space, or high ambient temperatures.

B. System Design

  • Choose the appropriate condensing unit and evaporator capacity based on the storage room size and intended temperature range.
  • Ensure the PU sandwich panels' thickness aligns with the required insulation level.

C. Material Procurement

  • Source high-quality equipment and materials from trusted suppliers like PT. BJT Indonesia, ensuring reliability and longevity.
  • Verify that all components comply with industry standards and certifications.

D. Team Coordination

  • Assemble a team of skilled technicians experienced in cold storage installations.
  • Develop a clear timeline and ensure all safety protocols are in place.

3. Installation Process for Condensing Units and Evaporators

A. Installing the Condensing Unit

  1. Placement

    • Install the condensing unit in a well-ventilated area to ensure optimal heat dissipation.
    • Use anti-vibration pads to minimize noise and extend equipment lifespan.

  2. Mounting

    • Secure the unit to a sturdy base using bolts and brackets.
    • Ensure proper alignment to avoid strain on connected pipes and electrical components.

  3. Piping and Wiring

    • Connect the refrigeration piping between the condensing unit and evaporator.
    • Use insulated pipes to reduce heat transfer and prevent energy loss.
    • Install electrical wiring according to manufacturer specifications, ensuring proper grounding.

  4. Leak Testing

    • Conduct a pressure test to detect any leaks in the refrigeration system.
    • Seal leaks using appropriate methods before proceeding.

B. Installing the Evaporator

  1. Placement Inside the Room

    • Mount the evaporator on the ceiling or wall, depending on the design.
    • Ensure even airflow distribution for uniform cooling.

  2. Connection to the Refrigeration System

    • Link the evaporator to the condensing unit using refrigerant pipes.
    • Ensure airtight seals at all connection points to prevent refrigerant leakage.

  3. Drip Tray Installation

    • Install a drip tray to collect condensate from the evaporator.
    • Connect the tray to a drainage system to avoid water accumulation.

  4. Electrical Setup

    • Wire the evaporator fan and defrost system to the control panel.
    • Test the system for proper functionality.

4. Installation of PU Sandwich Panels

PU sandwich panels are the building blocks of the cooling storage room. Installing them correctly ensures maximum energy efficiency and durability.

A. Floor Installation

  • Lay a vapor barrier to prevent moisture from seeping into the insulation.
  • Install PU panels with proper alignment and secure them using adhesive or fasteners.

B. Wall Installation

  1. Panel Assembly

    • Begin from one corner and work outward, ensuring tight joints between panels.
    • Use tongue-and-groove connectors for seamless assembly.

  2. Sealing Joints

    • Apply insulation foam or silicone sealant at joints to prevent air leakage.
    • Double-check for gaps or misaligned panels.

  3. Door Installation

    • Install insulated doors, ensuring they fit tightly within the frame.
    • Test the door for proper opening, closing, and sealing.

C. Ceiling Installation

  • Secure ceiling panels to the wall panels using brackets and fasteners.
  • Ensure proper alignment to avoid stress points or gaps.

5. System Integration and Testing

Once all components are installed, integrating the system and conducting thorough testing is essential.

A. Refrigerant Charging

  • Fill the refrigeration system with the recommended type and amount of refrigerant.
  • Monitor pressure gauges to ensure proper charging.

B. Electrical Testing

  • Check all electrical connections for continuity and safety.
  • Test the control system, including temperature sensors and alarms.

C. Performance Testing

  • Run the system for 24–48 hours to monitor cooling performance.
  • Measure temperature consistency and adjust settings as needed.

D. Final Inspection

  • Inspect the entire installation for any mechanical, electrical, or structural issues.
  • Address any identified problems before handing over the facility to the client.

6. Maintenance Tips for Longevity

Regular maintenance is crucial to ensure the cold storage room operates efficiently for years to come.

  • Clean the Evaporator Coils: Remove dust and debris to maintain optimal airflow.
  • Check Refrigerant Levels: Monitor for leaks or drops in refrigerant pressure.
  • Inspect PU Panels: Look for signs of wear, gaps, or damage.
  • Service the Condensing Unit: Clean the condenser coils and check the compressor’s performance.
  • Schedule Routine Inspections: Engage professionals like PT. BJT Indonesia for regular maintenance and repairs.
