Description
Technical field
The utility model relates to air-conditioning technical field, more particularly, relates to the air conditioner combined unit of a kind of multiple stage.
Background technology
At present, traditional air conditioner unit many employings unit operation, when needs adopt multiple stage unit operation, usually, the control (as opened or closing) that each single unit runs is controlled by artificial manual operations, thus, realize the adjustment to whole air-conditioning system load, this kind of mode of operation exists following not enough:
1) complex operation and accuracy rate is lower.
2) if can not reasonable distribution operating unit, then low the or average abrasion of unit effective rate of utilization can be caused to increase.As: when unit load demand is less, if unreasonable distribution, the every platform unit that then there will be in system is all in operation at part load state, is so unfavorable for the average abrasion of energy saving of system and compressor, result in whole Air-condition system control loaded down with trivial details and impact use comfortableness.
In sum, how to make one to have each air-conditioner set in the system of multiple stage air-conditioner set operation, according to different load State Science, reasonable automatic operation, become the technical problem that those skilled in the art are urgently to be resolved hurrily.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of according to workload demand and size, and reasonable, science also distributes one or more air conditioner combined unit of multiple stage run automatically.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
The air conditioner combined unit of multiple stage of the present utility model is made up of main air-conditioner set and auxiliary air-conditioner set paired running, between the COM1 and the COM1 of auxiliary air-conditioner set controller of main air-conditioner set controller, be connected with the shielding multiple twin order wire that length is no more than 30 meters, startup temperature difference restrictive condition and the startup priority parameters of the water temperature of air-conditioning system, main air-conditioner set and/or auxiliary air-conditioner set are arranged in the controller of main air-conditioner set.
The outfall sewer of this Unit erriger is connected to main air-conditioner set exit branch and auxiliary air-conditioner set exit branch collects node.
Described main air-conditioner set and auxiliary air-conditioner set share same intake pump.
Compared with prior art, the shielding multiple twin order wire that length is no more than 30 meters is connected with between the air conditioner combined unit of multiple stage of the present utility model main air-conditioner set wherein and the controller COM1 of auxiliary air-conditioner set, wherein, the water temperature of air-conditioning system, main air-conditioner set or auxiliary air-conditioner set startup temperature difference restrictive condition and start priority parameters and be arranged in the controller of main air-conditioner set.The utility model automatically can control the start of main and auxiliary air-conditioner set, shutdown and regulate unit load, thus regulate the load of whole air-conditioning system, must to be started shooting to each unit or the drawback of power-off operation by artificially manual when it can effectively avoid multiple stage unit to apply together.
Accompanying drawing explanation
Fig. 1 is one of structural representation of the present utility model.
Fig. 2 is structural representation two of the present utility model.
Detailed description of the invention
As shown in Figure 1, the air conditioner combined unit of multiple stage of the present utility model is made up of two cover system units, be respectively main air-conditioner set (being called for short main frame in accompanying drawing) and auxiliary air-conditioner set (being called for short subsidiary engine in accompanying drawing), all containing compressor, condenser, evaporimeter, several check valves, electric expansion valve and unit water pump and controller etc. in every cover system unit.
Main air-conditioner set, auxiliary air-conditioner set independent operating separately, can only one group of operation, also can run simultaneously.
The utility model is connected with the shielding multiple twin order wire that length is no more than 30 meters between main air-conditioner set controller and auxiliary air-conditioner set controller, wherein, the water temperature of air-conditioning system, main air-conditioner set or auxiliary air-conditioner set startup temperature difference restrictive condition and start priority parameters and be arranged in the controller of main air-conditioner set
What the outfall sewer in the utility model Unit erriger was connected to main air-conditioner set exit branch and auxiliary air-conditioner set exit branch collects node.
Outfall sewer is respectively arranged with main air-conditioner set leaving water temperature sensors and auxiliary air-conditioner set leaving water temperature sensors.Described leaving water temperature signal is the temperature signal collected by main air-conditioner set leaving water temperature sensors and auxiliary air-conditioner set leaving water temperature sensors.
Described main air-conditioner set and auxiliary air-conditioner set intake pump used can independently be arranged, and the utility model preferably shares an intake pump (as shown in Figure 2).
Described main air-conditioner set water inlet and leaving water temperature sensors are installed on the evaporimeter intake-outlet of main air-conditioner set, and described auxiliary air-conditioner set water inlet and leaving water temperature sensors are installed on the evaporimeter intake-outlet of auxiliary air-conditioner set.
Main air-conditioner set in the utility model and auxiliary air-conditioner set joint control mode following (being example in a chiller mode):
1) when the leaving water temperature in outfall sewer is higher than the leaving water temperature value set and cooling activation temperature approach (being usually set as 2.7 DEG C) sum, then think that air-conditioning system has workload demand, now main air-conditioner set and auxiliary air-conditioner set first start one according to average abrasion, after a unit starting in certain hour (such as 12 minutes), if the leaving water temperature collected is still higher than the leaving water temperature value of setting and when increasing level temperature approach (being usually set as 0.7 DEG C) sum, now, run a unit and can not meet workload demand, then need to open an other unit.
2) when the leaving water temperature in outfall sewer is lower than the leaving water temperature value set; then think that the workload demand of air-conditioning system is less; at this moment first off-load is wanted to the Unit erriger run; if after off-load during leaving water temperature value and the difference of certain value (be usually set as 0.5 DEG C) of described leaving water temperature still lower than setting; then first cut off a wherein unit according to average abrasion; if now described leaving water temperature is also low; such as lower than setting leaving water temperature value with shut down temperature approach (being usually set as 1.5 DEG C) difference time, then the single unit of remainder is also cut off.Start and stop unnecessary in order to avoid unit and add off-load, need to the startup of unit, shut down, add off-load and arrange rational temperature difference condition.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
