Central Air Conditioning Training & Testing Equipment

Order No. 66972215

? This central air conditioning trainer adopts PLC as the main controller, the running control of complete air
conditioning system is achieved by communication between computer and PLC. The running parameters
can be gathered by sensors and transferred to PLC through A/D module.
? Both manual control and computer control are available on this trainer. The manual control can be conducted by
using buttons on the panel of control cabinet, which are connected with related PLC input terminals.
? This system is composed of system control cabinet with control panel, system training objects, simulated room
and measuring meters. The training objects consist of refrigerating unit, cooling water system, chilled water
system and heat supply system. The control panel can be divided into five areas, they are main power operation
control area, control button and working state indicating area, AC contactor control area, frequency control area
and central control processor area.
? There are two frequency converters on frequency control area, which are used for the control of cooling water
pump and chilled water pump, the PT100 temperature sensor can gather the inlet/outlet water temperature
difference of chilled / cooling water and send the data through A/D module, PLC and D/A module, which will
be processed to 4-20mA analog quantity signal for driving frequency converter to start adaptive control.
? Safety precautions: overvoltage, overcurrent, overload, electric leakage and ground connection protections,
confirming to relevant national standards.
