Embodiment
The embodiment of the embodiment of the present invention is described in detail below in conjunction with accompanying drawing.It should be appreciated that this
The embodiment of place description is merely to illustrate and explain the present invention embodiment, is not intended to limit the invention embodiment.
Referring to Fig. 1, first aspect of the embodiment of the present invention provides a kind of wiring of air conditioner aerial temperature and humidity sensor
Detection method, the aerial temperature and humidity sensor includes air return temperature humidity sensor and air-supply Temperature Humidity Sensor.Wherein, return air

In the return air measured value ShWith the air-supply measured value SsComparative result meet wiring error set under the conditions of it is defeated
Go out wiring error alarm signal.
It should be noted that the work in order to provide the air return temperature humidity sensor and the air-supply Temperature Humidity Sensor
Power supply, is receiving return air measured value ShWith air-supply measured value SsBefore, it is necessary to connect the power supply of air conditioner, but air conditioner is not started shooting
Operation.
Further, since air conditioner is not started shooting during operation, in the temperature and humidity and ajutage of refrigerator return air inner air tube
The temperature and humidity correspondent equal of air is identical with the temperature and humidity of air in external environment condition.In air return humiture sensing
In the case that device and air-supply Temperature Humidity Sensor wiring error do not occur, the measured value of the two is generally corresponding to equal.Otherwise, it is larger
It is probably that air return temperature humidity sensor and/or air-supply Temperature Humidity Sensor wiring error occur.Now output connection false alarm
Signal, reminds operating personnel that the wiring to air return temperature humidity sensor and air-supply Temperature Humidity Sensor is detected.
The Wiring detection method of air conditioner aerial temperature and humidity sensor provided in an embodiment of the present invention is by receiving and comparing
When being not keyed up operation compared with air conditioner, the return air measured value S of air return temperature humidity sensorhAir-supply with air-supply Temperature Humidity Sensor is surveyed
Value SsDetected come the wiring to air return temperature humidity sensor and air-supply Temperature Humidity Sensor, by comparing two humitures
The measured value of sensor can know whether the two Temperature Humidity Sensors wiring error occur, so that air conditioner can be more
Plus air humidity is controlled exactly.
When wiring error occur in air return temperature humidity sensor and/or air-supply Temperature Humidity Sensor, relatively typically connect
Receive the return air measured value S of air return temperature humidity sensorhWith the air-supply measured value S of air-supply Temperature Humidity SensorsBetween deviation mistake
Greatly, i.e., described return air measured value ShWith the air-supply measured value SsDifference absolute value be more than or equal to setting value F when；Or
Say the measured value for not receiving air return temperature humidity sensor and air-supply Temperature Humidity Sensor at all, that is, the return air measured value received
ShAnd/or the air-supply measured value SsFor null value；When any one in above-mentioned two situations occurs, it can illustrate return air
Temperature Humidity Sensor and/or air-supply Temperature Humidity Sensor are likely to occur wiring error, now, output connection error alarm signal,
Remind operating personnel that the wiring to air return temperature humidity sensor and air-supply Temperature Humidity Sensor is detected.
Although above by the return air measured value S compared when air conditioner is not keyed up operationhWith air-supply measured value SsCan be one
Determine to detect whether air return temperature humidity sensor and air-supply Temperature Humidity Sensor wiring error occur in degree.Even if however, connecing
The return air measured value S receivedhWith air-supply measured value SsResult it is roughly equal, that is, return air measured value ShWith air-supply measured value
SsDifference absolute value be less than setting value F, two Temperature Humidity Sensors can not be excluded completely does not have the possibility of wrong.Example
Such as, when mistake is by air return temperature humidity sensor and reversed air-supply Temperature Humidity Sensor, two temperature and humidity sensings can still be received
The measured value of device, and two measured values are basically identical.Therefore, in order that obtaining wiring testing result more accurately and reliably, this hair
The method that bright embodiment is provided also includes：
Receiving return air measured value ShWith air-supply measured value SsDifference absolute value be less than setting value F when, start air-conditioning
Device start operation setting time T；

In the return air measured value ShtWith the air-supply measured value SstComparative result meet wiring error and impose a condition down
Output connection error alarm signal.
Specifically, after air conditioner start operation setting time T, air is entered by the backwind tube of refrigerator, in refrigerator
Discharged, condensed after the water vapour heat release in air by ajutage after heat release, air humidity reduction.Therefore, refrigerator system is being passed through
After cold, air themperature and humidity in ajutage can be reduced compared to the air themperature and humidity in backwind tube, so that, just
In the case of true wiring, the return air measured value S of air return temperature humidity sensorhtBy the air-supply to should be higher than that air-supply Temperature Humidity Sensor
Measured value Sst.By comparing return air measured value ShtWith air-supply measured value SstAir return temperature humidity sensor and air-supply temperature can be known
Whether humidity sensor there is wiring error.
When operating modes of air conditioner is different, the return air measured value S of air return temperature humidity sensorhtWith air-supply Temperature Humidity Sensor
Air-supply measured value SstAlso it is different.For example, when air conditioner runs on heating mode, the return air measurement of air return temperature humidity sensor
Value ShtAir-supply measured value S by correspondence less than air-supply Temperature Humidity Sensorst.And when air conditioner runs on refrigeration mode, return air
The return air measured value S of Temperature Humidity SensorhtBy the air-supply measured value S to should be higher than that air-supply Temperature Humidity Sensorst。
Preferably, in the embodiment of the present invention, starting air conditioner start operation setting time T includes：Start the air conditioner
Start runs setting time T in a chiller mode.
After air conditioner starts shooting operation setting time T in a chiller mode, the return air measured value of its air return temperature humidity sensor
ShtWith the air-supply measured value S of air-supply Temperature Humidity SensorstIt has been tended towards stability that, be convenient for data comparison, and return air measured value
ShtStably higher than air-supply measured value Sst。
When air conditioner runs on refrigeration mode, the wiring error impose a condition including：In the return air measured value Sht
With the air-supply measured value SstDifference Sht-SstDuring less than or equal to setting value D, output connection error alarm signal, and make sky
Adjust device out of service, in order to which operating personnel carries out wiring check.
Further, in the return air measured value ShtWith the air-supply measured value SstDifference be more than setting value D when, explanation
Air return temperature humidity sensor and the wiring of air-supply Temperature Humidity Sensor are correct, now, stop wiring detection.
As it was previously stated, the air return temperature humidity sensor and the air-supply Temperature Humidity Sensor can both measure air themperature
Value can also measure air humidity value.Therefore, when carrying out wiring detection, it can use any one in temperature value and humidity value
Person is as referential data, or it is highly preferred that regard temperature value and humidity value as referential data simultaneously.It is, the return air
Measured value ShIncluding return air temperature measured value ThAnd/or return air humidity measurements Hh；The air-supply measured value SsIncluding wind pushing temperature
