What is the primary function of the economizer in a cooling system?

The primary function of the economizer in a cooling system is to reduce energy consumption. An economizer achieves this by utilizing outside air to cool the building when conditions are favorable, allowing the system to operate more efficiently. By leveraging the cooler outdoor temperatures instead of relying solely on mechanical refrigeration, the economizer helps to decrease the overall energy demand on the cooling units.

The role of an economizer is particularly significant in reducing the need for compressor operation, thus saving energy and lowering operating costs. The additional functionality, like increasing the refrigeration effect or stabilizing pressure, can arise from a more efficient system, but the main driving goal of incorporating an economizer is to minimize energy use while still achieving effective cooling.
