The invention relates to a central air-conditioning
refrigeration plant room
group control management system. According to the technical scheme, the central air-conditioning
refrigeration plant room
group control management system comprises a
supervisory control computer, an information input and
output device and an
Ethernet switch, wherein the information input and
output device and an Ethernetswitch are connected with the
supervisory control computer; the
Ethernet switch is connected with a
serial port server, a PLC and a main
machine valve control box group, a
refrigeration pump control cabinet group, a cooling pump control cabinet group, a
cooling tower control cabinet group and a
cooling tower valve control box group; the PLC is connected with a temperature sensor, a
pressure sensor, a flow sensor and an outdoor
atmospheric temperature and
humidity sensor; a refrigeration pump control cabinet includes a refrigeration pump starting loop and performs starting and stopping and thespeed regulation control over a refrigeration pump; a cooling pump control cabinet includes a cooling pump starting loop and performs starting and stopping and the speed regulation control over a cooling pump; and a
cooling tower control cabinet includes a cooling
tower starting loop and performs starting and stopping and the speed regulation control over a cooling
tower. The technical problems that the degree of
automation is low and the operation of equipment is not balanced are solved, and the central air-conditioning
refrigeration plant room
group control management system is suitable forrefrigeration
plant room systems of various pipeline connection topologies.
