Abstract
The invention discloses a method for detecting ambient temperature of the indoor unit of a VRV. By optimizing the sequential control of the switching signal of the indoor unit, the electric machine of the indoor unit and an air deflector electric machine, when a control program compares the setting temperature with the indoor ambient temperature and judges, the temperature probe of the indoor temperature has sufficient heat exchange with the indoor air, so that the value detected by the temperature probe of the indoor ambient temperature is real, thereby making sure that the control program makes correct judgment and carries out proper action.
Description
Technical field
The present invention relates to the air conditioning control method field, exactly be meant a kind of method that detects the multi-online indoor machine environment temperature.
Background technology
At present, the environment temperature sensor of general air conditioner room unit is arranged into the air inlet of ducting system mostly, near the heat exchanger place.In many on-line systems, if open heating mode, the indoor set of not opening has cold-producing medium and flows through, and through the heat radiation of heat exchanger ambient.This moment, indoor set detected environment temperature can be than the environment temperature of reality high 6-15 ℃.Can judge and reach design temperature and do not start that the result who causes is that indoor set can't afford to drive if start the indoor set control program this moment, influence is used normally, causes client's complaint.
Summary of the invention
To above-mentioned defective; The technical problem that the present invention solves is to provide a kind of method that detects the multi-online indoor machine environment temperature; Realize that the numerical value that the indoor environment temperature probe detects is real, guarantee that control program makes right judgement, carry out reasonably action.
In order to solve above technical problem, the method for detection multi-online indoor machine environment temperature provided by the invention comprises the steps:
(1), when how online startup; When the control panel of indoor set receives starting-up signal, fixing rotating speed operation of the given indoor motor of control program, meanwhile; Wind guide strip reaches the angle of a given anti-cold wind under the drive of wind guide strip motor, electronic expansion valve opening remains unchanged;
(2), the environment temperature of indoor set probe detects environment temperature;
(3), after the elapsed time interval delta T, control program will this moment the value and the design temperature of detected indoor environment temperature compare;
(4), control program again according to this fiducial value judge this indoor set whether the needs start heat:
If the value of detected indoor environment temperature is lower than design temperature, then carries out and heat operation according to normal control program;
If the value of detected indoor environment temperature is greater than or equal to design temperature; Then close indoor motor, wind guide strip reaches closing angle under the drive of wind guide strip motor simultaneously.
Preferably, in the step (3), time interval Δ T is 15-180 second.
Compared with prior art; The method of detection multi-online indoor machine environment temperature provided by the invention; Through optimization SECO to indoor set switching signal, indoor machine motor and wind guide strip motor; Guarantee that control program is carrying out design temperature and indoor environment temperature when relatively judging, the indoor environment temperature probe has carried out sufficient heat exchange with room air, thereby realizes that the indoor environment temperature numerical value that detects of popping one's head in is real; Guarantee that control program makes right judgement, carry out reasonably action.

The specific embodiment
For those skilled in the art can understand technical scheme provided by the present invention better, set forth below in conjunction with specific embodiment.
The method of the detection multi-online indoor machine environment temperature that the embodiment of the invention provides comprises the steps:
(1), when how online startup; When the control panel of indoor set receives starting-up signal, fixing rotating speed operation of the given indoor motor of control program, meanwhile; Wind guide strip reaches the angle of a given anti-cold wind under the drive of wind guide strip motor, electronic expansion valve opening remains unchanged;
(2), the environment temperature of indoor set probe detects environment temperature;
(3), after the elapsed time interval delta T, control program will this moment the value and the design temperature of detected indoor environment temperature compare;
(4), control program again according to this fiducial value judge this indoor set whether the needs start heat:
If the value of detected indoor environment temperature is lower than design temperature, then carries out and heat operation according to normal control program;
If the value of detected indoor environment temperature is greater than or equal to design temperature; Then close indoor motor, wind guide strip reaches closing angle under the drive of wind guide strip motor simultaneously.
In step (3), time interval Δ T is 60 seconds.
See also Fig. 1, this figure is the control sequential chart of each electric component of indoor set start among the present invention.
Electric expansion valve state ON representes: the aperture of electric expansion valve during the normal heating operation of indoor set; Electric expansion valve state OFF representes: the minimum aperture of electric expansion valve during the indoor set heating operation.
Wind guide strip angle ON representes: wind guide strip normal operation under the drive of wind guide strip stepper motor (as putting wind or being fixed on any position); Wind guide strip angle OFF representes: wind guide strip turns to the position of closing air outlet under the drive of wind guide strip stepper motor; Wind guide strip angle FIX representes: wind guide strip turns to a fixing position wind of producing by boasting can not be blown on the human body under the drive of wind guide strip stepper motor.
Indoor motor state ON representes: the indoor motor energising drives wind wheel and rotates; Indoor motor state OFF representes: the indoor motor outage, wind wheel stops operating.
Indoor set state ON representes: the people can rotate the state that wind guide strip is opened by observed wind wheel directly perceived; Indoor set state OFF representes: the people is can observed wind wheel directly perceived motionless, and wind guide strip forwards the state of closing the air outlet position to.
T1 representes: the automatically controlled plate of indoor set receives the time of starting-up signal.T2 representes: the indoor set control program is made the judgement that whether reaches indoor set start condition, and determines whether to send the time that semaphore request increases can be needed to off-premises station.
Compared with prior art; The method of detection multi-online indoor machine environment temperature provided by the invention; Through optimization SECO to indoor set switching signal, indoor machine motor and wind guide strip motor; Guarantee that control program is carrying out design temperature and indoor environment temperature when relatively judging, the indoor environment temperature probe has carried out sufficient heat exchange with room air, thereby realizes that the indoor environment temperature numerical value that detects of popping one's head in is real; Guarantee that control program makes right judgement, carry out reasonably action.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the present invention.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation that does not break away from the spirit or scope of the present invention in other embodiments among this paper.Therefore, the present invention will can not be restricted to these embodiment shown in this paper, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
