Description of drawings
Describe the preferred embodiments of the present invention in detail with reference to Fig. 1, in Fig. 1, schematically show system and method for the present invention.
The specific embodiment
Present invention relates in general to (the HVAC﹠amp of system of heat supply, ventilation, air-conditioning and refrigeration; R), relate in particular to the method for so a kind of system and this system of operation, wherein the control of limited quantity input can be used for controlling independently the level of a greater number of this system.
Fig. 1 shows and comprises multi-stag cooling system 12 and thermostat 14, and this thermostat is used to control the operation of multi-stag cooling system 12.
This system 12 comprises a plurality of levels 16,18,20, is three levels in this case, the common components that each grade comprises compressor and be used for the vapor compression circuit of required refrigerating function.This system also comprises microprocessor 22, and it can communicate with each level 16,18,20, and communicates by letter with thermostat 14.Microprocessor 22 is preferably used in the input of reception from thermostat 14, and can utilize this to import and control each level 16,18,20, and this will be described below.
As mentioned above, thermostat 14 normally has the device of a limited number of outputs, is labeled as y1 and y2 in this case.In addition, conventional system has a limited number of inputs usually so that receive this input, and the microprocessor in the present invention 22 has the input with the output equal number of thermostat 14.Therefore, the input 24 of microprocessor 22 is suitable for receiving the output from thermostat 14, and is suitable for this input is transformed into a large amount of being used for by the demand output not at the same level of control system 12.
According to the present invention, input y1 and y2 are changed or are converted to binary system, so that be used to characterize more relatively a large amount of different instruction subsequently, described instruction sends the not at the same level of system 10 to.
In following table 1,2,3, clearly listed this situation.

Table 1 shows the form of classical control system, and wherein when input y1 connected, microprocessor started the first order of cooling system usually, and when input y2 connects, starts all levels of this system.Like this, import y1, y2 and control this system by this way in this system, that is, having only a level or three levels is (active) that can effectively control.
Opposite with the mode shown in the table 1, input y1 can be used for starting two levels, and input y2 starts all levels.This provides such control operation, that is, two levels or three levels of this system can effectively be controlled.
Yet, it is evident that the mode shown in table 1 and the table 2 can not realize such mode of operation, that is, each grade in the level 0,1,2,3 of this system can effectively be controlled.
According to the present invention, input is transformed into binary system control system as shown in table 3, makes the combination of different inputs and the quantity of input have symbolical meanings thus, so these two signal inputs can be transformed into four different instructions.This advantageously makes the system with two inputs can handle with the grade of four different levels at work as shown in table 3ly, and to compare this with the control system of routine be particularly advantageous.
Should be appreciated that the system that system and method for the present invention can advantageously be applicable to the system with a large amount of inputs and have the level of greater number.For example, thereby can provide the system with three inputs according to the present invention, wherein these three inputs are transformed into eight different specific instruction of binary system control system, therefore eight cooling class can be set.Similarly, the system of four inputs can control 16 different levels.
Further advantageously, this can combine with having the multi-stag system of cooling off and heating two kinds of abilities, preferably cools off and heat all to have a plurality of levels.In this case, a limited number of inputs can be used for controlling a plurality of levels of cooling, a plurality of levels and the combination thereof of heating.
In this system, for example this system has four inputs and all has three levels for cooling and heating, and conventional system can not be used to provide each not at the same level handling fully flexibly.Yet, according to the present invention, and shown in following table 4, from the input of level 1 and 2 and show cooling or non-refrigerated the 3rd input can be used for providing the flexible control operation of each grade He all grades of this system, reserve the 4th input simultaneously and be advantageously used in and represent different information.
