When operator scheme being input in the input block 51, automatically priority control model or manual priority level control model are selected, operator precedence level with control air-conditioning 50 and ventilation unit 60, and when manual priority level control model was selected, the user selected the operator precedence level relevant with air-conditioning 50 and ventilation unit 60.
Air-conditioner controller 54 comprises microcomputer, and this microcomputer is exported the compressor control signal that is used for opening/closing compressor 55 according to the comparative result between indoor temperature Tr and the target temperature Ts.If select to be used for the priority control operation of air-conditioning 50 and ventilation unit 60 by input block 51, then air-conditioner controller 54 compares outdoor temperature To and preset reference temperature T 1 and T2, determine current season then, thereby according to carrying out refrigeration/heating operation the season of determining.Can be a season in spring, summer, the fall and winter current season.Yet general plotting of the present invention is not limited thereto.For example, can be between spring and summer current season, between summer and autumn, a period between the fall and winter and/or between winter and spring.
When operator scheme being input in the input block 61, automatically priority control model or manual priority level control model are selected, operator precedence level with control air-conditioning 50 and ventilation unit 60, and when manual priority level control model was selected, the user selected the operator precedence level relevant with air-conditioning 50 and ventilation unit 60.
If the user does not select to be used for the priority control model of air-conditioning 50 and ventilation unit 60, then the priority control model is defaulted as automatically automatic priority control model.In addition, when operating air conditioner 50 and ventilation unit 60 under the priority control model, even critical dustiness (Em: under refrigeration/heating operation condition, the CO in the inner space
2Critical concentration) and critical-temperature (Tm: under the ventilation operation condition, the critical temperature value of inner space) be not imported in the input block 61 yet default settings automatically.
Simultaneously, though the air-conditioner controller 54 of independent structure and the example that Ventilation Control device 63 is described to realize the air-conditioning system of general plotting according to the present invention, but according to the design condition and the demand of air-conditioning system, also can be by integrally constructing air-conditioner controller 54 and Ventilation Control device 63 uses the wire/wireless controller.In addition, the input block 51 of air-conditioning 50 can be integrated into the single input block as single input module with the input block 61 of ventilation unit 60.
Below, use description to operate the effect of equipment of air-conditioning system and the method for operation sequence and control air-conditioning system with said structure.
Fig. 3 is the flow chart according to the method for control air-conditioning of the operator precedence level in the air-conditioning system and ventilation unit that according to the present invention general plotting embodiment is shown.
As the primary condition that is used for according to the description purpose of the operation of present embodiment, a plurality of indoor units 20 (for example, indoor unit 1-1,1-2,1-3 ...) and a plurality of unit ventilators 30 (for example, unit ventilators 1-1,1-2,1-3 ...) be installed in the space, and be configured in the air-conditioning system same group (group 1, group 2 ... perhaps organize N), described air-conditioning system has the integrated structure of air-conditioning 50 and ventilation unit 60.Below, with the method for describing as the priority control air-conditioning system in any a group in the predetermined group of the basis of example.
At first, the user selects automatic priority control model or manual priority level control model (operating procedure S100) by the input block 51 of air-conditioning 50 or the input block 61 of ventilation unit 60.
Therefore, air-conditioner controller 54 and Ventilation Control device 63 determine whether selected priority control model is manual priority level control model (operating procedure S200).If selected priority control model is not a manual priority level control model, then air-conditioner controller 54 and Ventilation Control device 63 determine that selected priority control model is automatic priority control model (default mode is automatic priority control model), thereby controller 54 and 63 is by temperature T o (operating procedure S300) outside outdoor temperature sensor 53 sensing chamber.
Detected outdoor temperature To is compared with the first reference temperature T1 that presets (being used for determining that the outdoor temperature in season is about 30 ℃).If outdoor temperature To equals or is higher than the described first reference temperature T1, determine that then be summer season, thereby when the operator precedence level is distributed to air-conditioning, carry out refrigerating operation (operating procedure S600).
If outdoor temperature To is lower than the described first reference temperature T1, then outdoor temperature To and the second reference temperature T2 (for example, being used for determining that the temperature in season is about 0 ℃) are compared.If outdoor temperature To is equal to or less than the second reference temperature T2, determines that then be winter season, thereby when the operator precedence level is distributed to air-conditioning, carry out heating operation (operating procedure S600).
On the contrary, if outdoor temperature To is lower than the first reference temperature T1 and/or is higher than the second reference temperature T2, determine that then be spring or autumn season, thereby when the operator precedence level is distributed to ventilation unit, carry out ventilation operation (operating procedure S800).
In this case, the first reference temperature T1 and the second reference temperature T2 can be by the manufacturer of air-conditioning system or user presets.When the first reference temperature T1 and the second reference temperature T2 not when default, the first reference temperature T1 and the second reference temperature T2 are set to default value.
If the priority control model is automatic priority control model (a perhaps default mode), then in the surrounding environment of considering air-conditioning system, need the operator precedence level be distributed to air-conditioning or ventilation unit based on season.Usually, when outdoor temperature To equals or be higher than 30 ℃, summer can be defined as, perhaps when outdoor temperature To is equal to or less than 0 ℃, winter can be defined as.Therefore, when being distributed to air-conditioning, the operator precedence level carries out refrigeration/heating operation.Other temperature conditions can be represented spring or autumn, thereby carries out ventilation operation when the operator precedence level is distributed to ventilation unit.
Simultaneously, when selected priority control model was represented manual priority level control model in operating procedure S200, controller determined whether the user has distributed to air-conditioning (operating procedure S700) with the operator precedence level.If the user has distributed to air-conditioning with the operator precedence level, then in operating procedure S600, open the air-conditioning control model.If the user does not distribute to air-conditioning with the operator precedence level, then in operating procedure S800, open the ventilation unit control model.
Below, describe when refrigeration/heating operation (operating procedure S600) performed according to selected priority control model or when season the operator precedence level being distributed to air-conditioning with reference to Fig. 4.
Fig. 4 is the flow chart that the method for the air-conditioning in the air-conditioning system of the general plotting embodiment according to the present invention is shown.
With reference to Fig. 3 and Fig. 4, open the air-conditioning control model, according to the quantity of the unit ventilators 30 that belongs to predetermined group and the quantity of indoor unit 20, can obtain exercisable aeration step number automatically by following equation 1.
Exercisable aeration step number=(the air velocity rank of unit ventilators * N)+1+ (M-1)
Here, the rank of the air velocity of unit ventilators 30 is divided into three ranks (senior, middle rank and rudimentary).N represents the quantity of unit ventilators 30, and M represents the quantity of indoor unit 20.
For example, if three unit ventilators 30 are connected to two indoor units 20, become one group, then as shown in Figure 5, the exercisable aeration step that obtains was 0 to 10 step automatically, and aeration step is from step 10.
Then, the user by air-conditioning 50 input block 51 input target temperature Ts (under refrigeration/heating operation condition, the target temperature of inner space) and critical dustiness Em (under refrigeration/heating operation condition, the CO in the inner space
2Critical concentration) (operating procedure S604) afterwards, open air-conditioning control model (operating procedure S606).
The operation of the heating/cooling assembly of air-conditioning 50 can be traditional heating/refrigerating operation.Because traditional heating/refrigerating operation is known technology, so followingly will omit detailed description.
If open the air-conditioning control model, be input to (operating procedure S608) in the air-conditioner controller 54 then by temperature T r in indoor temperature transmitter 52 sensing chamber of air-conditioning 50, and with this indoor temperature Tr.
Therefore, air-conditioner controller 54 interval calculation indoor temperature fall off rate V to schedule
T(operating procedure S610), the indoor temperature fall off rate V that is calculated
TDivided by preset reference temperature fall off rate V
TSThereby, calculate speed constant value K (operating procedure S612).
Then, the rate calculated constant value K of institute is compared with preset reference constant value Ks.If speed constant value K is less than reference constant value Ks, then indoor temperature fall off rate V
TBe in slow state.Therefore, aeration step is reduced by a step, reach with reference to constant value Ks (operating procedure S616) up to speed constant value K.
Here, according to season or outdoor temperature, according to the variation of speed constant value K with respect to reference constant value Ks, aeration step can not change (for example, reach with reference to constant value Ks up to speed constant value K, aeration step just can change).That is to say that the season of determining according to speed constant value K with in a plurality of season, aeration step can change or can not change.
During the air-conditioning control model, the current dustiness Er of the inner space that contaminant sensor 62 detection air-conditionings 50 move therein, dustiness Er being input to Ventilation Control device 63 (operating procedure S618), and Ventilation Control device 63 is with detected indoor pollution degree Er compare with default critical dustiness Em (operating procedure S620).
Result as above-mentioned comparison, if indoor pollution degree Er subcritical dustiness Em, then described controller is determined room air also haze-free (dirty (contaminated)), determines then whether the current indoor temperature Tr of inner space has reached target temperature Ts (operating procedure S622).If indoor temperature Tr does not reach target temperature Ts, then control program turns back to operating procedure S608, to carry out the air-conditioning control model.
As above-mentioned definite result, if indoor temperature Tr reaches target temperature Ts, then the air-conditioning control model stops, to stop refrigeration/heating operation (operating procedure S624).
In addition, in operating procedure S620, even when indoor pollution degree Er is equal to, or greater than critical dustiness Em, the air-conditioning control model is stopped, to stop refrigeration/heating operation (operating procedure S624).
If the air-conditioning control model is stopped, then described controller determines whether the priority control model represents automatic priority control model (operating procedure S626).If the priority control model is represented automatic priority control model, executable operations step S800 then, thus open the ventilation unit control model.If the priority control model is not represented automatic priority control model, then because the user has manually selected the air-conditioning control model, so control model is fixed to current air-conditioning control model, rather than the ventilation unit control model.Therefore, executable operations step S608.
Simultaneously, if speed constant value K is greater than reference constant value Ks, then indoor temperature fall off rate V
TBe in normal condition.Therefore, aeration step does not change to rudimentary, and in operating procedure S618 sensing chamber's internal contamination degree Er.
Here, according to season or outdoor temperature, according to the variation of speed constant value K with respect to reference constant value Ks, for example, speed constant value K is greater than reference constant value Ks, and aeration step can change.That is to say that the season of determining according to speed constant value K with in a plurality of season, aeration step can change or can not change.
Below, the details (operating procedure S800) of priority control model of determining about basis or the ventilation operation of carrying out under the ventilation unit control model season is described with reference to Fig. 6.
Fig. 6 is the flow chart of method that the ventilation unit of the operator precedence level in the air-conditioning system of the general plotting according to the present invention is shown.
Referring to figs. 1 through Fig. 6,,, calculate automatically and then definite exercisable aeration step (operating procedure S802) by equation 1 then according to the quantity of the unit ventilators 30 in the group and the quantity of indoor unit 20 if the operator precedence level is assigned to ventilation unit.The scheme of calculating aeration step is identical with the scheme of calculating the air-conditioning control model.
For example, if two indoor units 20 are connected to three unit ventilators 30, become one group, then as shown in Figure 5, the exercisable aeration step that obtains was 0 to 10 step automatically, and aeration step is from the first step.
Simultaneously, because when opening the ventilation unit control model after execution air-conditioning control model, in the air-conditioning control model, aeration step is confirmed as adjustable aeration step, can omit determine (the operating procedure S802) of aeration step.
After this, the user import target stains degree Es (during ventilation operation, the CO of inner space
2Aimed concn) and critical-temperature Tm (during ventilation operation, the critical temperature value of inner space) (operating procedure S804) afterwards, opens ventilation unit control model (operating procedure S806).
The operation of the ventilation unit under the ventilation unit control model is typical ventilation operation.In addition, because typical ventilation operation is a known technology, so followingly will omit detailed description.
If open the ventilation unit control model, then the contaminant sensor 62 of ventilation unit 60 detects the current dustiness Er of inner space, so that this dustiness Er is input to (operating procedure S808) in the Ventilation Control device 63.
Therefore, Ventilation Control device 63 is with the indoor pollution degree Er that is detected compare with target stains degree Es (operating procedure S810).If indoor pollution degree Er is not more than target stains degree Es, then the ventilation unit control model is stopped, to stop ventilation operation (operating procedure S818).
If the result illustrates indoor pollution degree Er greater than target stains degree Es, then Ventilation Control device 63 determines that room air is dense, thereby makes aeration step increase by a step from current step, reaches target stains degree Es (operating procedure S812) up to indoor pollution degree Er.
During the ventilation unit control model, indoor temperature transmitter 52 detects the current indoor temperature Tr of the inner space of carrying out ventilation operation therein, so that this indoor temperature Tr is input to (operating procedure S814) in the air-conditioner controller 54, and air-conditioner controller 54 is with detected indoor temperature Tr compare with default critical-temperature Tm (operating procedure S816).
If result relatively illustrates indoor temperature Tr subcritical temperature T m, then Ventilation Control device 63 is determined not need heating/refrigeration room air, and turns back to operating procedure S808, to continue to carry out the ventilation unit control model.If indoor temperature Tr equals or is higher than critical-temperature Tm, then Ventilation Control device 63 stops the ventilation unit control model, to stop ventilation operation (operating procedure S818).
If the ventilation unit control model is stopped, determine then whether the priority control model represents automatic priority control model (operating procedure S820).If the priority control model is represented automatic priority control model, executable operations step S600 then, thus the operator precedence level is distributed to air-conditioning.If the priority control model is not represented automatic priority control model, mean that then the user has given ventilation unit with operator precedence level manual allocation, thereby the operator precedence level is not distributed to air-conditioning, and is assigned to executable operations step S808 under the state of ventilation unit in the operator precedence level.
General plotting of the present invention also can be embodied as the computer-readable code on the computer-readable medium.Described computer-readable medium can comprise computer readable recording medium storing program for performing and computer-readable transmission medium.Computer readable recording medium storing program for performing is can be by any data storage device of the data of computer system reads after can storing.The example of such computer readable recording medium storing program for performing comprises read-only storage (ROM), random-access memory (ram), CD-ROM, tape, floppy disk and optical data storage device.Computer readable recording medium storing program for performing also can be distributed on the network that connects computer system, thereby stores and computer readable code executed according to distributed mode.The computer-readable transmission medium can transmit carrier wave or signal (for example wired the or wireless data by the internet transmits).In addition, the programmer in field can easily explain function program, code and the code segment that is used to realize general plotting of the present invention under the general plotting of the present invention.
