In this article, you can check what it is, what it is, what is the benefit of the condensing unit (CU). Now, let's explain the points that need to be considered at that time to determine which CU is best suited for each type of application.

Studying and analyzing the available space is a very important point in selecting the condensing unit. Many CUs are based on metal plates or "railways", although the goal is always to pursue standardization, but its size is not standard in all cases.

Another focus of the physical space is the compressor's home. Different home compressors have different heights, so you should be careful not to be a problem when assembling.

For example, the Embraco Condensing Unit is designed by engineers specializing in refrigeration. Therefore, the size of each set of CU is appropriate to ensure that the customer's technical reliability.

Due to dimensional accuracy, you can choose a unit based on the capabilities developed by the compressor.

This ability depends on the operating point, such as temperature, evaporation and condensation, which we will see in more detail in the next step.

The condensing unit needs to be selected according to the application, such as a freezer and a beverage refrigerator. One of the main items is the desired evaporation temperature in the cooling system, depending on the "application" (evaporation) of the compressor being approved and ready for work.

Each compressor, so the evaporation range of each condensing unit is different. Therefore, when selecting CU, always check the compressor evaporation range. Can be evaluated by technical data sheet. You can select the product and view this important information.

If you need to use UCs of different fluids used with previous systems, you must check that the operating pressure (evaporation and condensation) is within the safety threshold of the system piping.

In addition to the above discussion, pay attention to power. Make sure to select the condensing unit that supplies the same voltage and frequency.

The starting torque is also analyzed. In systems where expansion valves are used, care must be taken if the compressor has a high starting torque in the condensing unit.

Do you consider these steps when selecting and adjusting the condensing unit?
