ET 915.07 Climatisation Module Show data sheet (pdf file) Print page
Technical Description
The ET 915.07 experimental set-up is arranged on a clearly laid out board, which is mounted on the basic unit ET 915. The pipe connection between the basic unit and the additional module is via self-locking Schrader valves. Individual components of the system, in this case the compressor, fan, heater, humidifier and solenoid valves, are actuated using the software included with the basic unit. The ET 915.07 represents a model of an air conditioning system with recirculating or fresh air operation. The refrigerating capacity is generated by an evaporator. A fan moves the air to be conditioning through a ventilation duct containing an integrated air humidifier and an adjustable air valve. Heating elements can be used to heat the air. Solenoid valves enable the unit to be operated with a capillary tube or an expansion valve as the expansion element.
