The embodiment of figure description is exemplary, it is intended to for explaining the present invention, and is not considered as limiting the invention.
Controlled below in conjunction with the accompanying drawings to describe the failure of the temperature-sensitive bag of frequency-variable module in the air-conditioning system of proposition of the embodiment of the present invention
The temperature-sensitive bag Failure Control device of frequency-variable module and there is the temperature-sensitive in method processed, computer-readable recording medium, air-conditioning system
The air-conditioning system of bag Failure Control device.
In an embodiment of the present invention, air-conditioning system may include compressor, the frequency-variable module for controlling compressor and right
The temperature-sensitive bag for answering frequency-variable module to set.
Fig. 1 is the flow of the temperature-sensitive bag Failure Control method of frequency-variable module in air-conditioning system according to embodiments of the present invention
Figure.As shown in figure 1, the temperature-sensitive bag Failure Control method of frequency-variable module may include following steps in the air-conditioning system：
S1, the temperature of frequency-variable module is obtained by temperature-sensitive bag.
S2, judges whether the temperature of frequency-variable module is more than or equal to the first preset temperature, and it is short to judge whether temperature-sensitive bag occurs
Road/open circuit.
Wherein, the first preset temperature T1 can be demarcated according to actual conditions, for example, the first preset temperature T1 can be 70
℃。
S3, if the temperature of frequency-variable module is more than or equal to the first preset temperature or short/open occurs for temperature-sensitive bag, sentence
Disconnected temperature-sensitive bag fails.
Specifically, the magnitude of voltage at temperature-sensitive bag both ends can be detected by hardware circuit come judge temperature-sensitive bag whether occur short circuit/
Open circuit, wherein, when the magnitude of voltage at temperature-sensitive bag both ends is zero, judge that short circuit occurs for temperature-sensitive bag；Magnitude of voltage at temperature-sensitive bag both ends
For hardware circuit operating voltage when, judge that temperature-sensitive bag is opened a way, when temperature-sensitive bag occur short circuit or open circuit when, all will determine that sense
Thermometer bulb fails.In addition, when the temperature of the frequency-variable module obtained by temperature-sensitive bag exceedes certain value, temperature-sensitive bag also will determine that
Fail, for example, after the water inlet of temperature-sensitive bag, temperature-sensitive bag will not occur short circuit or open a way, but the change obtained by temperature-sensitive bag
Very large deviation occurs in the temperature Tm of frequency module, such as temperature Tm >=70 DEG C of frequency-variable module, now judges that temperature-sensitive bag fails.
S4, when temperature-sensitive bag fails, the running frequency of compressor corresponding to current outdoor environment temperature is reduced by the

According to one embodiment of present invention, if the disorderly closedown for not receiving air-conditioning system in the first preset time takes
Disappear signal, then controls air-conditioning system to be in holding state.
Further, according to one embodiment of present invention, if not receiving the disorderly closedown signal of air-conditioning system,
Compressor is controlled to keep current state constant.
Specifically, after judging that temperature-sensitive bag fails, by the operation frequency of compressor corresponding to current outdoor environment temperature
Rate reduces the first predeterminated frequency, and controls compressor operating according to the running frequency after reduction.Operation frequency after according to reduction
During rate control compressor operating, air-conditioning system is also possible that other failures, it is therefore desirable to real-time judge air-conditioning system
Whether system receives other disorderly closedown signals.Wherein, when not receiving the disorderly closedown signal of air-conditioning system, control compression
Machine keeps current state constant, that is, controls compressor and run with the running frequency after reducing；Receiving the failure of air-conditioning system
During stopping signal, determine whether that the disorderly closedown that air-conditioning system whether is received in the first preset time eliminates signal, wherein,
If the disorderly closedown that air-conditioning system is received in the first preset time eliminates signal, illustrate air-conditioning system in the first preset time
The failure of system is recovered automatically, now controls compressor to keep current state constant, that is, controls compressor with the fortune after reducing
Line frequency is run；If the disorderly closedown for not receiving air-conditioning system in the first preset time eliminates signal, illustrate that first is pre-
If the failure of air-conditioning system can not be recovered automatically in the time, now air-conditioning system is controlled to be in holding state.Thus, in certain journey
It can ensure that system continues safe and reliable operation on degree, improve the experience sense of user.
