Details About Packaged Systems & Separate Condensing Units

Condensing units are an essential part of any residential and commercial heating and air conditioning system. Without a condensing unit, your customers’ HVAC systems would be unable to adequately operate, making them essential for a wide range of industrial and household cooling applications. However, your customers are likely not familiar with the differences between packaged systems and standalone condensing units. 

And you should be the one to explain to your clients not just why they should choose one or the other, but also how each of these separate systems operates and what the benefits of each one are. Based on the specifications and the advice you provide, your clients will be able to reach an informed decision on the type of unit best suitable for their particular requirements. That is why you should learn more about these different units and the features and benefits they offer. 

What Are The Different Types Of Condensing Units?

A condensing unit is a temperature-control device that is primarily used in chillers, heat pumps, air conditioners, and refrigeration systems. They are in charge of moving the energy by compressing refrigerant by using a system of coils and the cool air around them. There are several parts vital for adequate operation of condensing units – coils, pumps, fans, and electronic controls. 

Condensing units come in several different types. The three most common varieties of modern condensing units are: 

  • Air-cooled condensing units: These condensing units consist of a condenser cooled by air, a refrigeration compressor, and other ancillary components. They are suitable for a wide range of industrial and commercial cooling applications, including: 
    • Process cooling
    • Food retail
    • Food service
    • Cold storage warehouses
    • Commercial refrigeration

Their most common varieties include units with vertical, horizontal, and dual vertical air discharge capabilities. These differences make them suitable for different commercial or industrial applications and varying spaces and installation requirements. 

Some of the biggest advantages of air-cooled condensing units include: 

o    Simple operations

o    Small size

o    Low maintenance requirements

o    Easy cleaning

o    Low installation costs

o    Flexible applications

  • Water-cooled condensing units: These units essentially represent a heat exchanger system used for removing heat from various air conditioning and refrigeration processes by allowing water to run through it. The water basically condenses the vapor and releases heat into the water that continues to cool the process. 

The common applications of water-cooled condensing units are:

o    Food retail and service

o    Commercial refrigeration

o    Process cooling

Water-cooled condensing units are widely used due to their numerous advantages, including: 

o    Suitability for spaces with space restrictions

o    Good recovery of thermal energy for use in other processes

o    Durability and longevity

o    Quiet operations

o    Enhances energy efficiency

o    Possibility for indoor housing

o    High rate of heat transfer

What Are Packaged Systems?

Packaged systems combine a condensing unit and a cooler within a single package, which allows for reduced refrigerant charge and faster installation procedures. This, in turn, saves energy, money, and time for you and your customers. Common applications of packaged units are similar to those of separate units. 

Biggest advantages of packaged units include: 

  • Less space for installation
  • Streamlined and easy maintenance
  • Lower utility bills
  • Enhanced versatility
  • High cooling capacity for the size and energy consumption

What Are The Most Important Features To Look For?

It doesn’t matter if you’re recommending a packaged or a separate condensing unit to your customers – there are some features both of these types of units should have. The most important characteristics are: 

  • Availability of finned stainless steel coils and finned copper tubes for better protection against corrosion.
  • Blades made from aluminum.
  • Connection manifolds for single refrigerant.
  • Mounted expansion valves that enhance installation speed.
