Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present application, the technical scheme in the embodiment of the present application is clearly and completely described, obviously, described embodiment is only some embodiments of the present application, instead of whole embodiment.Based on the embodiment in the application, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the application's protection.
The embodiment of the present application discloses a kind of air-conditioner and control method thereof, to solve under existing control mode, and the problem that normal operation is subject to the impact of temperature sensor excessive, air-conditioning utilization rate is low of air-conditioner.
With reference to Fig. 1, the control method of the air-conditioner that the embodiment of the present application one provides, comprises the steps:
S101: whether detection ring temperature sensor and pipe temperature sensor break down respectively;
S102: and if only if when described ring temperature sensor breaks down, determines Fisrt fault pattern, and air-conditioner described in start and stop periodically; Air-conditioner start after with described Fisrt fault mode operation.
Wherein, when above-mentioned Fisrt fault modal representation detects ring temperature sensor fault, the operational mode of air-conditioner, is specifically as follows refrigeration mode, dehumidification mode or heating mode.
Applicant finds, when ring temperature sensor fault, owing to current environment temperature can not being detected, therefore air-conditioner can not judge refrigerating/heating demand according to environment temperature and user's design temperature, also with regard to uncontrollable air-conditioner according to demand refrigeration mode, dehumidification mode, heating mode and out of service between switch.And due to pipe temperature sensor fault-free; therefore as long as air-conditioner is not out of service, will still can normally carry out with the defencive function of U pipe temperature correlation (as the anti-high temperature function under anti-freeze function, heating mode under refrigeration mode etc.) under refrigeration mode, dehumidification mode and heating mode.
And the above embodiments of the present application detecting detecting that ring temperature sensor breaks down, pipe temperature sensor is when normal; determine the operational mode (being above-mentioned Fisrt fault pattern) of current air-conditioner; and periodicity start and stop air-conditioner; and operational mode when air-conditioner starts keeps above-mentioned Fisrt fault pattern constant, and can normally carry out with the defencive function of U pipe temperature correlation under this pattern.
For example, when detecting that ring temperature sensor breaks down, pipe temperature sensor is when normal, air-conditioner is just operating in heating mode (now Fisrt fault pattern is confirmed as heating mode), air-conditioner moves after duration reaches default duration (supposing that this default duration is t1) and stops under heating mode, wait stopping after accumulative total duration arrives another default duration (supposing that this another default duration is t2) restarting the operation of recovery heating mode; So circulation (being that cycle period is t1+t2).Wherein, in air-conditioner running, the U pipe temperature that still can detect according to pipe temperature sensor is carried out the defencive functions such as anti-high temperature.The occurrence of above-mentioned t1 and t2 can be determined according to practical application, in this no limit.
From said method step, the embodiment of the present application, detecting while only encircling temperature sensor fault, makes air-conditioner out of service no longer immediately, but determines operational mode now, and start and stop air-conditioner periodically, and the operational mode of air-conditioner while starting is above-mentioned definite operational mode.Therefore, in the situation that only encircling temperature sensor fault, air-conditioner still can meet fault definite refrigerating/heating demand before, be unlikely to completely lose basic refrigeration and heat-production functions, thereby reduce to a certain extent the impact of temperature sensor on air-conditioner, improve the utilization rate of air-conditioner, solved the problem of prior art.
It should be noted that, the fault detect to ring temperature sensor and pipe temperature sensor in above-described embodiment step S101, can be to detect in real time, also can detect once every certain duration.In arbitrary moment in the cyclic process of air-conditioner periodicity start and stop, if detect, the malfunction of ring temperature sensor or pipe temperature sensor changes, or, receive the instruction of user's remote-control closedown, the cyclic process of dwelling period start and stop.In addition, if two equal fault-free of sensor, air-conditioner normally moves.
With reference to Fig. 2, the control method of the air-conditioner that the embodiment of the present application two provides, comprises the steps:
S2100: whether detection ring temperature sensor and pipe temperature sensor break down respectively;
S2200: and if only if when described ring temperature sensor breaks down, determines the now operational mode of air-conditioner, i.e. Fisrt fault pattern; If Fisrt fault pattern is refrigeration mode or dehumidification mode, perform step S2211, if Fisrt fault pattern is heating mode, perform step S2221;
S2211, control air-conditioner move with refrigeration mode, and start refrigerating operaton timing t

S2213, wait for timing duration t when described refrigeration
c2reach default refrigeration waiting time t
c2' time, start air-conditioner and with refrigeration mode operation, will freeze and wait for timing duration t
c2zero clearing, starts refrigerating operaton timing t
c1, and return to step S2212;
S2221, control air-conditioner move with heating mode, and start heating operation timing t
h1;
S2222, as heating operation timing duration t

S2223, wait for timing duration t when heating
h2reach the default waiting time t that heats
h2' time, start air-conditioner and with heating mode operation, will heat and wait for timing duration t

The embodiment of the present application two provides that and if only if when ring temperature sensor breaks down, the periodically concrete grammar of start and stop air-conditioner.Wherein, default refrigerating operaton duration t
c1', default refrigeration waiting time t
c2', default heating operation duration t

With reference to Fig. 3, the control method of the air-conditioner that the embodiment of the present application three provides, comprises the steps:
S3100: whether detection ring temperature sensor and pipe temperature sensor break down respectively; And if only if when described ring temperature sensor breaks down, execution step S3200; And if only if when described pipe temperature sensor breaks down, execution step S3300;
S3200: determine Fisrt fault pattern, and periodicity start and stop air-conditioner; Air-conditioner start after with described Fisrt fault mode operation;
Periodically the concrete grammar of start and stop air-conditioner can, with reference to embodiment bis-above, not repeat them here.
S3300: determine the second fault mode; In the time that this second fault mode is heating mode, execution step S3310; In the time that described the second fault mode is refrigeration mode or dehumidification mode, execution step S3320; In the time that described the second fault mode is air supply pattern, execution step S3330;
When above-mentioned the second fault mode represents to detect described pipe temperature sensor fault, the operational mode of air-conditioner, comprises refrigeration mode, dehumidification mode, heating mode and air supply pattern.
What S3310, the environment temperature T detecting according to ring temperature sensor and user set heats temperature T
rjudge whether to heat demand; If so, open compressor and cross valve, start to heat timing t
r, and continue execution step S3311, otherwise it is out of service to control air-conditioner;
Due to ring temperature sensor fault-free, thus the environment temperature T that can detect according to it and user set heat temperature T
rjudge under current environment whether heat demand, concrete judgment mode can, with reference to prior art, not repeat them here.After compressor and cross valve are opened, air-conditioner starts to heat, and makes environment temperature increase.
S3311, when heating timing duration t
rreach the default first duration t that heats
r1' time, close cross valve, will heat timing duration t

ljudge whether refrigeration demand; If so, open compressor, inner blower and outer blower fan, close cross valve, the first timing t starts to freeze
l1, and continue execution step S3321, otherwise it is out of service to control air-conditioner;
S3321, when refrigeration the first timing duration t
l1reach default refrigeration the first duration t
l1', and environment temperature T is less than default antifrost temperature T ' time, close compressor and outer blower fan, the first timing duration t will freeze
l1zero clearing, and the second timing t that starts to freeze
l2;
Due to pipe temperature sensor fault, cannot carry out antifrost protection according to the U pipe temperature of evaporimeter.Therefore, be the device frosting that avoids evaporating, in air conditioner refrigerating process, if environment temperature is lower than default antifrost temperature T ' time, close compressor and outer blower fan, only keep inner blower operation, makes evaporimeter defrost.
S3322, when refrigeration the second timing duration t
l2reach default refrigeration the second duration t
l2' time, opening compressor and outer blower fan, the second timing duration t will freeze
l2zero clearing, the first timing t restarts to freeze
l1, and return to step S3321;
From step S3321 and S3322, in the time only having pipe temperature sensor fault, if there is refrigeration demand, control air-conditioner refrigeration and defrost two states under circular flow (cycle period is t
l1'+t
l2'), in meeting refrigeration or dehumidifying demand, device frosting avoids evaporating.
S3330, close compressor, outer blower fan and cross valve, control inner blower and move according to user's wind speed setting.
From said method, the embodiment of the present application is in the time ring temperature sensor or pipe temperature sensor fault being detected, no longer control air-conditioner out of service, for only having ring temperature sensor situation about breaking down, the periodically start and stop of operational mode control air-conditioner of the embodiment of the present application air-conditioner during according to fault; For the situation of only having pipe temperature sensor fault, the environment temperature still detecting according to ring temperature sensor judges refrigerating/heating demand, meet heat demand in, prevent off-premises station frosting: if desired heat, control air-conditioner heat and the two states that defrosts under circular flow; If desired refrigeration or dehumidifying, controls air-conditioner circular flow under refrigeration and defrost two states, and in meeting refrigeration demand, device frosting avoids evaporating.Therefore; with respect to prior art; the embodiment of the present application has ensured only encircling temperature sensor fault or only pipe temperature sensor fault in the situation that; air-conditioner can continue to realize basic refrigerating/heating function and corresponding defencive function; under the prerequisite of guarantee equipment and personal safety; reduce the impact of temperature sensor on air-conditioner, improved the utilization rate of air-conditioner, solved the problem of prior art.
Further, with reference to Fig. 4, in other embodiment of the application, above-described embodiment by step S3310～S3312 meet heat demand in, can control inner blower by the following method, realize the anti-cold wind function under heating mode:
S41, starting to heat timing t
