Multiple compressor condensing units are an innovation in the HVAC industry. These types of units are well-known for their flexibility, adaptability, and the ability to cater to a wide array of potential commercial applications.

It is this kind of versatility that has made multiple compressor condensing units a popular choice among many contractors and end users. Let’s explore how these units are different from standard condenser units, how they operate, and what their benefits and key features are.

What Are Condensing Units?

Condensing units are located outside of the property and they function as a heat exchanger that condenses a refrigerant from gaseous to its liquid state. The latent heat released during this process is then transferred to the coolant in the condenser. In this refrigeration cycle, the heat pump transports heat from a source with a low temperature to the heat sink with a higher temperature.

There are different types of refrigeration cycles, but the most common one uses electric motors to operate a compressor that is located within a condensing unit. Air conditioners function on the principle where a compressor causes changes in temperature between two different compartments and pumps the refrigerant around the system.

Condensing units compress refrigerant vapor and force it to go through a heat exchanger coil where it becomes liquid and rejects the head that was absorbed in the cool area indoors. THen, the heat exchanger gets cooled by fans that blow outside air.

What Are Multiple Compressor Condensing Units?

Multiple compressor condensing units are a more flexible and efficient alternative to standard single-compressor condensing units suitable for a greater variety of applications. The modular design of these condensing units generally allows for use of as many as three compressors within the same unit.

These types of condensing units are best suited for use in low and medium temperature applications, which makes them the perfect choice for convenience stores and restaurants where there are ice machines, display cases, or drink dispensers that require remote condenser circuits.

What’s more, multiple compressor condensing units are more energy efficient because they lower the heat load. Also, they possess several advanced  features that offer excellent refrigeration results and improve your customer’s bottom line.

What Are The Components of Multiple Compressor Units?

Multiple compressor units have many modern components that separate them from standard condenser units. Here are the most prominent components advanced multi compressor units have:

  • Fixe low and high pressure switches
  • Low pressure switch that can be adjusted on lower temperature modules
  • Suction ports for all modules
  • Suction accumulator
  • Sealed type suction filter and liquid line drier
  • Fin coils made from aluminium
  • Sight glass
  • Crankcase heater

What Are the Key Features & Benefits of Multiple Compressor Condensing Units?

Finally, multiple compressor condensing units bring many benefits and advanced features that make them the perfect choice for the commercial customers that have high requirements from their system.

  • Flexibility: These units come with a modular design capable of accommodating as many as three compressors, a very small footprint, and a rooftop appearance that easily blends with your existing equipment.
  • Lower installation costs
  • Easy serviceability: It is easier to service and maintain these units due to their clean piping and electrical layout and hinged panels that provide access to electrical and refrigeration components.
  • Durability and reliability: These units are durable and hard-wearing because they come with a galvanized steel frame, and with a one-year warranty on parts and a 4-year warranty on the compressor.
  • Enhanced energy efficiency: Multiple compressor units reduce the heat load, which lowers energy consumption and costs.

Silent operations: Vertical discharge and 1100 RPM motors lower noise levels.
