If passive climate control versions provide no sufficient heat dissipation, is the use of active systems to advise, in which the passive effects are reinforced by the use of technical equipment. Active enclosure air conditioning is based typically on filter or roof fans and heat exchangers or coolers. Ventilation systems must be used only for control cabinets, which according to DIN EN 60 529: 2009-9 allows air permeability is. The environment compared to closed, impermeable switch boxes require the use of heat exchangers. The cheapest variant of the active control cabinet air conditioning is the use of filter fans. You are only in relatively clean environments can be used, where is the outdoor temperature is below the desired internal temperature of the control cabinet. The use of heat exchangers is suitable for active air conditioning of air-permeable closed cabinets. There are air/air and air/water heat exchangers used, which differ considerably the performance and cost effectiveness.
The more expensive air/water heat exchanger cooling very effectively and can cool down the Interior of a control cabinet necessary, the outside temperature. High outdoor temperatures may necessitate the use of refrigerators, which are due to their cold machines able to cope with a large amount of waste heat. Cabinet heaters used for cabinets outdoors, exposed to the risk of condensation often, which maintain a constant, avoid condensation temperature. Each control cabinet air conditioning requires accurate taking into account relevant technical and environmental Conditions. As a single structure, she should be professional planned and executed.
