Table 4
Table 5
The control system forms independent system all the way by using the mode of a freezing machine and a totally-enclosed compressor
Cooling system, each air-conditioner set module have the independent refrigeration system of two-way, each air-conditioner set module component units combined type
Module unit.It certainly, can also be by system parameter setting at single compressor module unit.Compressor combination number of units and block combiner
Number of units set-up function is the control completed based on a Standard Control Procedure to disparate modules number.The basis completely of manual operator 1 powers on
The compressor combination number of units and block combiner number of preceding setting determine the compressor number of units that need to be put into operation, also determine access control
The number of the outdoor air conditioner unit of network.As compressor networking number of units be set as 2, number of modules be set as 3, when working on power
When access control network outdoor air conditioner unit number be 3 pieces, operating compression board number be 6, all and compressor operating
The related control function of number of units such as operational management function, energy adjustment function are handled by 6 compressors.
The control system has following control function:
(1) compressor prevents frequent start-stop, and it is 3 minutes that compressor, which is again started up interval time, i.e., the compressor shutdown time is not
Less than 3 minutes.
(2) compressor equilibrium operating, in air-conditioner set use process, balanced random start compressor, to reach all pressures
The stopping of contracting machine is identical with runing time.
(3) fuzzy control Rule adjusting, load when T wind >=T sets+T difference, T set holding when < T wind < T sets+T difference, and T sets -2
Unloading when DEG C < T wind≤T is set, emergency stop when T wind≤T sets -2 DEG C, wherein T wind is return air/return water temperature, and T is set as return air/return water
Set temperature, T difference are actuating range.Such as 12 DEG C of set temperature, 2 DEG C of actuating range, whens water temperature >=14 DEG C, loads, 13 DEG C of guarantors
It holds, 10 DEG C of water temperature≤12 DEG C < unloadings, water temperature≤10 DEG C emergency stop；The above load, unloading, holding, emergency stop are by certain temperature control week
Phase is identified that the temperature control period is adjustable.Specifically, it loads, keep, unloading and the meaning of emergency stop is as follows: loading zone: each one
The temperature control period executes a loading procedure, loads a compressor every time；Unloading area: it in each temperature control period when unloading, holds
Row unloads a compressor with this uninstall process every time；Holding area: keeping a temperature control periodic state in the area, than
A temperature control period as above opens a set modules, into the region after no longer execute load, uninstall process, still save out one
The state of set modules；Emergency stop area: closing two compressors every time, and every minor tick is no more than 5 seconds.It should be noted that temperature control week
Phase answers viewing system size appropriate adjustment, is then uniformly controlled by manual operator 1 for multiple set modules.
(4) freezing machine/cooling pump control, when there is compressor requirement starting, two freezing machines, which put into operation, (to defrost
When stop)；Freezing machine just stops working when all compressors all stop.
(5) line traffic control switch 209 controls, when being closed line traffic control switch 209, system operation；When disconnecting line traffic control switch 209,
System-down.
(6) run-limiting function, is compressor time-out limitation function, and specific operation is provided in system parameter setting
After number of days, manual operator 1 will complete the limitation to air-conditioner set runing time according to accumulative unit runing time function, when unit is tired
When meter runing time reaches setting number of days, unit is by automatic shutdown, and unit is locked at this time, and unlock needs to have corresponding authority
Engineer carries out system parameter setting modification.
(7) power failure memory function, manual operator 1 manages working condition when unit powers on automatically, if system parameter setting
Power failure memory function, then when unit middle power-off in operating status, manual operator 1 can the automatic Memory unit power-off before shape
State, when being again powered up, manual operator 1 can automatically put into operation according to normal start-up course.
(8) timed power on/off, air-conditioner set can execute automatically booting, shutdown according to the open and close machine time set.
(9) protection and troubleshooting, 1. manual operator 1 has phase-detection phase shortage and anti-phase defencive function, which can lead to
It crosses system parameter and is configured modification；2. air conditioner water flow detection, water pump starts to detect air-conditioning water flow after starting 30 seconds, works as inspection
Measure air conditioner water underfed and continue to setting time after, insufficient if it is main control module 2 water flow, then system is complete
Stop, it is insufficient if it is sub- 3 water flow of control module, then only close all devices of corresponding sub- control module 3；3. antifreeze open of freezing
The detection of 211 escapes is closed, when system runs cooling condition, when detecting 211 escape of frost prevention switch, closes corresponding control module
All compressors；4. compressor high voltage protective closes corresponding compressor when system detection is excessively high to compressor high pressure；⑤
Compressor low-voltage variation closes corresponding compression after system detection is too low to compressor low pressure and time that continue to setting
Machine locks failure, re-powers reset after Failure elimination；It should be noted that low-voltage variation shields when system defrosting；6. sensing
Device error protection, when 2 outlet air of main control module/leaving water temperature sensors 219 break down, system is closed, group control module
3 outlet air/leaving water temperature sensors 219 are simply turned off corresponding sub- control module 3 when breaking down；When system return air/return water temperature
System is closed when sensor 218 breaks down；7. evaporator outlet air/leaving water temperature abnormal protection, when outlet air/leaving water temperature is lower than
Setup parameter value and when continuing 30 seconds, system judges the too low protection of outlet air/leaving water temperature, when outlet air/leaving water temperature is higher than setting
When parameter value adds 2 degrees Celsius, failure reset；Wherein, it if outlet air/leaving water temperature abnormal protection occurs for main control module 2, closes
All compressors of system are closed, if outlet air/leaving water temperature abnormal protection occurs for sub- control module 3, are simply turned off corresponding son control
The compressor of molding block 3；8. communicating interrupt is protected, when a certain sub- control module 3 sends communicating interrupt, all outputs of the module are complete
Portion disconnects, but does not influence the work of other modules, if communicating interrupt occurs for main control module 2, system full cut-off.
Above embodiment is only preferred embodiments of the present invention, cannot be protected with this to limit the utility model
Range, the variation of any unsubstantiality that those skilled in the art is done on the basis of the utility model and replacement belong to
In the utility model range claimed.
