ATENG 12712 detail
- Two heating elements: one (pre-heater) situated at the evaporator inlet, power: 2000 W
- and other (re-heater) situated at the evaporator outlet, power: 1000 W.
Four hygrometers, placed along the tunnel, formed each one by two temperature sensors (wet and dry bulb).
Two steam lines inject steam from a steam generator (not included) to the tunnel to modify the air characteristics.
- Two windows of 200 x 300 mm to visualize the tunnel inside.
Evaporator. It consists of a finned radiator where a coolant flow circulates.
- Cooling circuit. It includes:
Compressor, 1/2 CV.
Filter.
Condenser.
High-pressure switch (it switch off the compressor when the pressure reach the fix pressure).
Expansion valve.
- Twelve temperature sensors, type �J�:
Eight temperature sensors (fourtemperature sensors (dry bulb) and four temperature sensors (wet bulb) to form four hygrometers).
- Four temperature sensors in the cooling circuit:
Two temperature sensors at the inlet and outlet of the evaporator and two temperature sensors at the inlet and outlet of the condenser.
- Flow meter to measure the coolant flow, range: 5 � 60 l/h.
- Inclined manometer to measure the air flow, range: 0 � 1� w.c. (water column).
- Three Bourdon manometers:
Manometer is situated at the evaporator inlet, other is situated at the evaporator outlet and the last one is situated at the condenser
outlet.
