Temporary cooling units

What are Temporary Cooling Units?

Temporary cooling units are portable machines generally supplied on flexible contracts for a fixed fee to meet a short short term need, and as such, are considered a non-permanent solution to heat removal. Although mostly considered as portable air conditioning units, other types include water chillers and HVAC air handling units for larger applications.

What are the Different Types of Temporary Cooling Units?

Below are some of the most common types of temporary cooling units;

  • Portable air conditioning units are as the name suggests highly portable units that can be delivered and installed easily and are suitable for smaller offices and spot cooling applications. Heat rejection is usually by means of air ducting.
  • Water cooled air handling units (AHU’s) are larger machines that can be positioned directly in a space or used with ducting to feed the air from the unit into work area. Cooling takes place inside the unit as air is moved over a water chilled heat exchanger. An external water chiller is required for this function.
  • Water chillers cool water that is passed through them. More often than not, these units are placed outside where the heat removed from the water is rejected to atmosphere using fans. The cooled water is then circulated and used to cool any number of processes including machinery and air conditioning.
  • Packaged Heat pump AHU’s are as the name suggests a one box air conditioning unit that includes fans and a refrigeration system that cools (and heats) the air flow. Because of their size and heat rejection fans these units are located externally and the air supply ducted.
