Climate chambers need to be cooled in order to perform effective heat exchange and cool the working volume. To perform this exchange, they have a condenser, which can be air-cooled or water-cooled, each with its own advantages and disadvantages. As we have seen above, air condensation is usually the standard for chambers with lower requirements. However, when high temperature gradients are required or the cooling unit’s performance is greater, it is advisable to use a water-cooled condenser, as this will help to reduce the heat and noise generated by the cooling unit. Furthermore, although air condensation is cheaper to install, it is less efficient, with higher operating costs due to its lower thermal efficiency, higher energy consumption and greater noise.
To do this, you need an external cooling unit (chiller) or a water cooling tower that supplies a continuous flow of clean, temperate water (between 5 and 30 ºC) to remove the heat generated during the cooling of the chamber, allowing you to handle more thermal load than air cooling. To avoid water consumption, the best option is a water recirculation unit, a closed circuit that continuously removes water. Another advantage of water-cooled units is that they are not as affected by the external conditions where the equipment is installed and generate less noise.
The disadvantage is that these types of systems require a more complex installation (pipes, pumps, etc.) and an additional investment for the external water cooling system.
