6 Safety Cooling units produced by Pfannenberg are designed for application dissipating heat from switch cabinets (IP 54). The cooling unit is only suitable for installing on the stationary operation. Only the authorized specialist can be work on the cooling system and electrical components.
Please refer to the attached technical specification for the details function of the cooling unit. 7.2 Operating principles The compressor (1) compresses the refrigerant until high pressure is achieved. During this process temperature increases. In the condenser (2) heat is dissipated to ambient air, the coolant becoming liquid. The condenser fan (5) of the compensate takes ambient air in through the condenser, and then it releases the air.In the expansion valve (3) the pressure of the coolant drops.
