Fig. 3 is the schematic diagram of the controller of the behavior for controlling HVAC unit of some exemplary embodiments according to disclosure theme.
Detailed description of the invention
A technical matters of disclosure theme reply is the control algorithm and the mechanism that need to change HVAC unit.In some cases, control algorithm and the mechanism of changing HVAC unit may complete actv. control more when not needing to change whole unit.In some cases, new control algorithm and mechanism may be used for controlling HVAC unit when not making HVAC send sub-audible sound or other sensory cues, and these sound and sensory cue may bother the people be near HVAC unit.In some cases, smart electric grid system can determine the control changing HVAC unit.Additionally or alternatively, control algorithm can be directed to the people of current use HVAC unit and personalized.
Some HVAC unit are used for receiving order in response to infrared (IR) signal such as sent through Long-distance Control and send sub-audible sound (such as " serge serge ").Sub-audible sound can to user instruction receive order and this order just by HVAC unit process.But sub-audible sound and other similar sensory cues may be less desirable, when by the order transmitted be not sent by user time.In some exemplary embodiments, HVAC unit can send some promptings leaving user alone, such as changes display, opens LED or closes LED etc.
A lot of HVAC unit has iFeel feature (being also known as " follow me (Followme) ").In the disclosure, iFeel feature is following feature: in this feature, the temperature relevant to the operation of HVAC unit or other parameters at unit from not measured with it, but measured and be sent to HVAC unit in some other positions.According to disclosure theme, HVAC unit is used for: in response to receiving by the parameter transmitted as a part for iFeel feature, do not send any sub-audible sound or sensory cue, the operation of this iFeel feature is contrary with the operation of other the non-iFeel features when receiving other the non-iFeel signal transmissions such as from the order of Long-distance Control.
In some exemplary embodiments, the transmission of measured parameter can be adjoint by other order institutes such as changing fan speed, change target temperature etc. being sent to HVAC unit.In some exemplary embodiments, measured parameter can be measured and do not measured by HVAC unit self in any position.This position can be fixing or movement.In some exemplary embodiments, the Long-distance Control of HVAC unit may be used for measurement parameter and wirelessly order is sent to HVAC unit.In some exemplary embodiments, HVAC unit can according to its current state, observed reading and utilize its control algorithm to control himself operation.The message being transferred into HVAC unit according to iFeel feature can be called iFeel message.
A technical scheme is to provide a control unit, this control unit use iFeel feature thus use iFeel agreement by simulation, synthesis or " forgery " observed reading be sent to HVAC unit, thus made this unit make desired behavior by the observed reading transmitted.Therefore, possible iFeel message can not reflect the true measurement of sensor, but reflects the different observed reading that produces, thus makes HVAC unit making a response like that as required or desirably.
Consider the specific iFeel message of observed reading (such as, the temperature of report) and the expected value (such as, target temperature) providing report, the response of specific HVAC unit model can be determined in advance.Such as, sending the iFeel message with the measuring tempeature of 17 DEG C when target temperature is 25 DEG C can cause HVAC automatically to stop the motor (such as, when being in refrigeration mode) of compressor.In some cases, HVAC unit can automatically by fan-speed settings to the low speed in these situations.Because use iFeel feature, when not sending any sub-audible sound or not providing any other prompting attempting to be sensed by user, this operation can be performed.
Therefore, consider that data are to (T, S), wherein T is included in the observed reading that provides in iFeel message (such as, temperature, humidity etc.) and S be HVAC unit can comprise expected value (such as, target temperature, target humidity etc.) current state, all unit of same model may be used for responding with the R of predetermined behavior, instruction.In these cases, predefined action can be determined by the control algorithm of HVAC and mechanism.Each model for HVAC unit can obtain mapping (T, S) → R.In certain embodiments, the user inputting the observations of discrete cell behavior can provide this mapping.Use user interface can provide this mapping, user can select the behavior of iFeel and target measurement value and needs by this user interface, such as, and compressor open/close state, fan speed, fan directional, turnover panel motion etc.
In an alternative embodiment, mapping can be set up in advance and be saved with computer-readable format.Exemplarily, mapping can be stored in computer readable file, and this file is preserved with any computer-readable format and mapped.Additionally or alternatively, mapping can be stored in data memory.
In another embodiment, manually or automatically by HVAC unit be set to particular state S, reporting measurements T and observe response R, this mapping can be obtained, also referred to as the change of the behavior made or behavior.
Once it is available for mapping (T, S) → R, so reverse Mapping can be determined, thus for each for S and R, wherein S is current state and R treats, by the behavior change made or required behavior, can determine corresponding T, namely treat by the observed reading reported.Exemplarily, if the behavior expected is close compressor and fan speed is adjusted to low, and the current state of HVAC unit comprises the target temperature of 25 DEG C and operation mode is refrigeration mode, and so mapped observed reading can be 17 DEG C.In some exemplary embodiments, mapping (T, S) → R can not be injective function.In some cases, there is multiple optional observed reading T
1, T
2.T
n, thus when HVAC is in state S, these observed readings are mapped to identical required behavior R.For the single observed reading outside above-mentioned optional measurement set, reverse Mapping can be map (S, R).
In some exemplary embodiments, when control algorithm is determined to change to be applied to the expectation of the behavior of HVAC unit (such as, open or close motor, fan speed is adjusted high/low, change turnover panel direction, or otherwise affect the operation of HVAC unit), this control algorithm can search for the combination being used for current state and required behavior in reverse Mapping.Once have found this combination, the observed reading be associated with this combination is retrieved.Then the current state that there is no need to react true measurement is transmitted by iFeel message with the combination of the observed reading determined, thus HVAC unit really presents desired behavior and do not produce sub-audible sound.
In certain embodiments, the current state of HVAC unit does not need to be transmitted by iFeel message.In these embodiments, the observed reading determined is only had to be transmitted, although temperature determination algorithm internally may be followed the tracks of the state of HVAC unit and use this state of HVAC unit.
In an alternative embodiment, if HVAC unit supports this agreement, so required behavior instead of observed reading can be sent to HVAC unit by iFeel message and HVAC unit presents required behavior.Required behavior can transmit from any control unit, such as determines the unit of required behavior or any external unit.
