Air conditioning

The industrial climate has become increasingly important in recent years. Was formerly the heat of the components active cooling today be discharged or passively increasingly in demand. Passive cooling was realized as recordable only by the heat dissipation through the cabinet surface through ventilation grille or thermal coupling of particularly heat-problematic components. The disadvantages are but with the different methods are obvious: the surface cooling is too dependent on the site and on the ambient temperature. Open air vent control cabinet while for fresh air, but also for unwanted foreign matter / deposits, which in turn can lead to a failure of the system. The thermal coupling ultimately leads to conscious formation of hot spots. All three cooling concepts have one big disadvantage together: they are not or poorly controllable.

With active cooling, the heat dissipation is controlled. As a basis for adequate cooling solution one must first determine the basic data: How much cooling capacity I need anything, the cooling performance is continuously demanded what conditions prevail at the location of the cabinet, there are limitations in terms of space, volume, tension? After these considerations, one should select the appropriate cooling components. 


Filter fan / cabinet fan / roof vent

filter fan of plastic material forming the easiest way to segregated heat removal on a control panel. The integrated filter dust from entering the greatest extent possible, filter mats can be even after installation replaced or cleaned easily and quickly.

Compressor / enclosure cooling units

enclosure cooling devices have a closed refrigeration circuit. In this circuit, a gaseous refrigerant is compressed by a compressor and thus heated, the refrigerant is now under high pressure. It is cooled in the condenser and thereby changes its physical state from gas to a liquid, but the high pressure remains. The constant pressure build-up of the compressor, the liquid refrigerant is forced through a capillary tube into the evaporator, thereby degrading printing and evaporated. In this case cold is released to the environment.

Peltier / Thermoelectric cooling devices

, the principle of the Peltier cooling corresponds to an electric heat pump. The Peltier elements transport the heat energy from the cold exchanger in the cabinet interior to the heat exchanger in the cabinet outside. The warm air inside the cabinet is blown by a fan on the cold exchanger and thereby cooled. The heat exchanger in the cabinet outside is then cooled with ambient air. Advantage of Peltier cooling is mainly the functional reliability. There are no liquids, and thus no danger of leakage.

Air / air air / water heat exchanger

heat exchanger based on the principle of indirect heat transfer. Here, the internal circuit and the external circuit is separated, then, by passing each other out heat flows a heat exchange. The simplest form of this system is an air / air heat exchanger, however, (eg., Water), the effectiveness can be increased by the selection of heat transfer medium.

Recooler / chiller

recooler (also called chiller) serve primarily to to cool in most cases, water or oil is a liquid. The liquids are used as heat transfer medium and absorb the heat of the heat source and transport them through pipes or tubes for heat exchanger. There, the liquid heat is removed from the medium is cooler and is reintroduced into the circulation. The heat transfer medium circulates in a separate, closed circuit.
