Abstract:
     The invention relates to a central air-conditioning system simulation equipment, which is composed of the computer, the simulation signal analog unit, the frequency converter frequency interface unit, the RS232/485 converting unit, the interface unit and the digital display meter. The simulation signal analog unit and the frequency converter frequency interface unit are connected to the computer through the 485 bus and two RS232/485 converting units. The output ports of the host computer signal analog unit, the host computer instantaneous power analog unit and the frequency converter frequency interface unit are connected to the control cabinet through the communication wires. There is a digital frequency display meter at the output port of the frequency converter frequency interface unit. The output ports of the temperature signal analog unit, the flow capacity signal analog unit and the pressure difference signal analog unit are connected to the controller cabinet through the same number of the interface units and the 485 buses respectively. There is the digital temperature display meter, the digital flow capacity display meter and the digital pressure difference display meter at the output port of the temperature signal analog unit, the flow capacity signal analog unit and the pressure difference signal analog unit respectively.
