Evaporative Condensers

Medium and large refrigeration systems often use water cooled condensers, especially when using ammonia as refrigerant. This type of condensation makes it possible to achieve consistency of performance, thermal efficiency (both in cold and warm season), solving the typical problems of air-cooled condensers (high condensing temperature with an increase in pressure of the circuit, considerable efficiency decrease). In most of these systems the water is cooled by open or closed type cooling towers.

A particularly interesting solution is to use directly an evaporative condensers that has a heat exchanger (coil), inside of which the refrigerant is flowing and condensing (freon or ammonia) optimizing the efficiency. The use of water is minimal reducing the consumption and obtaining the highest efficiency.
