Outdoor condensing units are becoming increasingly crucial in the commercial refrigeration sector, serving an essential function in various applications such as remote refrigerated cabinets, cold rooms, freezer rooms, walk-in coolers, and walk-in freezers.

These units are composed of several key components, including a refrigeration compressor, condenser, fan motor, receiver, dryer filter, sight glass, solenoid valve, high and low-pressure switches, accumulator, high and low-pressure gauges, electrical controls, and waterproof casing.

Proper installation of outdoor condensing units is paramount. As these units operate independently from the refrigerated cabinets or cold storage and are typically positioned outside the storage area or building, choosing the right location for an outdoor condensing unit is critical to ensure optimal performance and efficiency.

Install Outdoor Condensing Unit

  1. Selecting the Right Location

Accessibility: Choose a location that allows easy access for maintenance and repairs.

Ventilation: Ensure the unit will have plenty of space around it for air circulation; avoid placing it in enclosed spaces.

Sunlight: If possible, install the unit in a shaded area to improve efficiency.

Noise: Consider the noise the unit will generate and its impact on the surrounding area.

Ground Level: The unit should be installed on a level surface. Use a concrete pad or mounting brackets to secure it off the ground.

  1. Preparing the Site

Clear the Area: Remove any debris, vegetation, or other obstacles from the installation site.

Install a Base: Prepare a concrete pad or secure a mounting frame to place the unit on. The base should be level and stable.

  1. Installing the Unit

Positioning: Place the condensing unit on the prepared base. Make sure it’s level.

Securing the Unit: Fasten the unit to the base using appropriate anchors or bolts to prevent it from tipping or vibrating excessively.

  1. Electrical Connections

Wiring: Follow the manufacturer’s wiring diagram to make the electrical connections. This typically involves connecting the power supply and the control wiring between the condensing unit and the indoor evaporator unit.

Safety: Ensure all electrical work complies with local codes and regulations. It’s advisable to have a certified electrician make or verify the electrical connections.

  1. Refrigerant Lines

Routing: Connect the refrigerant lines between the outdoor condensing unit and the indoor evaporator coil. Ensure the lines are properly insulated.

Leak Testing: After connecting the refrigerant lines, perform a leak test to ensure there are no leaks in the system.

  1. Commissioning the System

Vacuuming: Evacuate the refrigerant lines and the indoor coil to remove any moisture or air.

Charging Refrigerant: Charge the system with refrigerant according to the manufacturer’s specifications.

Testing: Start the system to ensure it’s operating correctly. Check for any unusual noises, ensure the cooling is functioning, and verify that all controls work as expected.

Optimized Location Selection

Avoid Areas with Animals and Plants: Ensure the installation site is away from areas where animals are kept and plants are grown to prevent the outdoor unit from being blocked.

Stay Clear of Flammable and Explosive Areas: Choose a location away from places where flammable and explosive gas leaks might occur.

Consider Airflow and Wind Direction: Avoid places directly facing strong winds to ensure condenser efficiency.

Distance from Corrosive Gases: Do not choose locations near facilities for seawater chemical treatment, drying ovens, or areas with heavy vehicle exhaust.

Clean, Unobstructed Environment: The site should be away from oil, falling leaves, and insect gatherings to avoid condenser blockage.

Good Drainage Conditions: Select a location with good ground drainage so that defrost water can be quickly drained off. If necessary, carry out drainage construction.

Minimize Impact on Neighbors: Ensure the outdoor unit’s air outlet is not directly facing the neighbor’s windows to avoid noise issues.

Consider Snow Accumulation: In cold regions, choose a location without snow accumulation and take measures to prevent snow, ice, and frost in winter.

Ground Bearing Capacity: Ensure the chosen installation site has sufficient strength to bear the weight of the outdoor refrigeration condensing unit.

Routine Maintenance of Outdoor Condensing Units

  • Check that motors and fan blades are operating smoothly, without any vibrations or friction.
  • Ensure that the condenser fins are free of dust and debris.
  • Inspect refrigerant pipes for any signs of looseness or vibration.
  • Monitor the refrigerant for signs of moisture or depletion.
  • Check contactors for any signs of looseness or damage.
  • Inspect relays and electronic components for damage.
