Referring to Fig. 2, an embodiment of the choke detecting method of coolant circulating system of the present invention is described in the present embodiment cold
The choke detecting method of matchmaker's circulatory system includes:
Step S10, the running parameter of coolant circulating system within a preset time interval is obtained, the running parameter includes room
The temperature change value of interior heat exchanger；
In one embodiment, the running parameter of coolant circulating system within a preset time interval is obtained, wherein work as air conditioner
When operating in different conditions, different prefixed time intervals can be set, for example, when air conditioner is to first power on, when presetting
Between be spaced and can be set to 10 minutes, when air conditioner is currently in operating status, prefixed time interval can be 6 points
Clock.It is described first power on can be air-conditioning for the first time be switched on, and or the air conditioner unused time be greater than preset time threshold after again
Booting.It is understood that completing opening for the first time for air conditioner when air conditioner is installed after booting for the first time refers to air conditioner factory
Machine process, the air conditioner unused time is greater than after preset time threshold booting again and refers to that air conditioner is not used for a long time, in institute
State the first time booting after the not used period.For example, air conditioner 1 month is the first time start process (institute after use
State the unused time can be set to 1 month greater than the time threshold in preset time threshold).
Running parameter in the prefixed time interval may include the temperature change value of indoor heat exchanger.It is indoor obtaining
When the temperature change value of heat exchanger, temperature sensor can be set on heat exchanger indoors, and then real-time according to temperature sensor
Obtain the real time temperature at each moment of indoor heat exchanger.In turn, existed according to the available indoor heat exchanger of the real time temperature
Maximum temperature values, minimum temperature value and temperature change value in prefixed time interval.
Step S20, judge whether the running parameter meets blocking condition；
Step S30, when the running parameter meets blocking condition, determine that the coolant circulating system blocks.
It in one embodiment, can be according to the temperature of indoor heat exchanger when getting the temperature change value of indoor heat exchanger
Changing value judges whether it meets blocking condition, wherein blocking condition can specifically include:
1, in booting preset duration, the temperature change value of the indoor heat exchanger is less than the first preset threshold；
2, during refrigerating operaton, the temperature change value of the indoor heat exchanger is greater than the second preset threshold；
3, in heating process, the temperature change value of the indoor heat exchanger is greater than third predetermined threshold value.
When checking air conditioner to be switched on for the first time, the timing since the moment that is switched on obtains when reaching prefixed time interval
Take the temperature change value of indoor heat exchanger.When coolant circulating system is completely plugged, refrigerant can not be recycled, and heat can not be by cold
Matchmaker's transmitting, the temperature so as to cause indoor heat exchanger and outdoor heat exchanger do not change.So the temperature of indoor heat exchanger becomes
Change value is smaller.It therefore is to judge the temperature change value of indoor heat exchanger whether less than the first preset threshold by blocking condition setting.
For example, first preset threshold can be 3 DEG C, i.e., in booting preset duration, if the temperature change of the indoor heat exchanger
Value then determines to meet blocking condition less than 3 DEG C.
When air conditioner operates in process of refrigerastion, the indoor heat exchanger temperature in any one available period becomes
Change value, wherein described any time period can be overlapped.For example, a prefixed time interval can be the 3rd on a time shaft
Minute to the 9th minute, is also possible to the 4th minute to the 10th minute.Wherein, the period can have overlapping portion on a timeline
Point, but time interval is fixed.Since air conditioner is in process of refrigerastion, the temperature of indoor heat exchanger is lower.When in the process of running,
When medium circulation pipeline is completely plugged suddenly, the temperature of indoor heat exchanger is quickly raised to close to room temperature.It therefore can be indoors
When the temperature change value of heat exchanger is greater than the second preset threshold, judgement meets blocking condition, wherein the second preset threshold can be
25℃。
When air conditioner operates in heating operations, the indoor heat exchanger temperature in any one available period becomes
Change value, and judge whether it is less than third predetermined threshold value.Since medium circulation pipeline is generally metal, and the importing performance of metal
Preferably, when refrigerant does not recycle, compressor makes what threshold value connected to follow since operational heat or other components are because of operational heat
Endless tube road, which has, receives certain heat, and then is transferred to indoor heat exchanger, thus even if when medium circulation pipeline is completely plugged,
The temperature of indoor heat exchanger is also slightly above room temperature, therefore what third preset value can be arranged is slightly less than the second preset threshold.Cause
This described third predetermined threshold value can be set to 20 DEG C.
It should be noted that in the present embodiment the first preset threshold, the second preset threshold third predetermined threshold value occurrence
It can freely be set by the producer of air conditioner, the occurrence designed in the present embodiment is only used for for example, being not used to limit
The fixed present invention.
When running parameter meets blocking condition, determine that the coolant circulating system blocks.
In the present embodiment, by obtaining indoor heat exchanger temperature change parameter, and when air conditioner operates in different works
When operation mode, according to judging whether heat exchange temperature running parameter meets corresponding blocking condition, and then the cold of air conditioner is judged
Whether matchmaker's circulatory system blocks.Since air conditioner can judge refrigerant circulation system according to the temperature change parameter of indoor heat exchanger
Whether system blocks, and therefore, the present invention is in current protection and exhaust shielding failure, the accurate coolant circulating system for determining air conditioner
It is whether completely plugged, compressor long-play is avoided, to extend the service life of air conditioner.
Further, it is based in an embodiment of the choke detecting method of coolant circulating system of the present invention referring to Fig. 3
Above-described embodiment, the temperature change parameter further include exhaust gas temperature change value, and the blocking condition further includes following at least one
It is a:

When, determine coolant circulating system blocking.
Specifically, real-time outlet air temperature is obtained, and then when air conditioner first powers on, is obtained within a preset time interval
The changing value for taking delivery temperature determines exhaust gas temperature change value when exhaust gas temperature change value is greater than default delivery temperature threshold value
Meet blocking condition.Wherein, presetting exhaust gas temperature change value can be with 10 DEG C.
Any one period is obtained when air conditioner operates in refrigeration or heating mode when that is, air conditioner is in operation
Interior exhaust gas temperature change value and its variation tendency.When delivery temperature changing value be greater than the default delivery temperature threshold value, and
When the delivery temperature downward trend, determine that exhaust gas temperature change parameter meets blocking condition.
In the present embodiment, delivery temperature parameter is heated in the blocking condition of coolant circulating system, so that judgment of clogging
It is more accurate, to reduce the probability of blocking erroneous judgement.

1, in booting preset duration, outdoor heat exchanger temperature change value is less than the first default outdoor heat exchanger temperature threshold
Value；
2, in refrigeration or heating process, the temperature change value of the outdoor heat exchanger is greater than the second default outdoor and changes
Hot device temperature threshold.
When coolant circulating system is completely plugged, since refrigerant can not recycle, thus the temperature of room switching heat-exchanger can be approached
Room temperature.When air conditioner, which is in, to be switched on for the first time, if coolant circulating system has blocked, the temperature change of outdoor heat exchanger compared with
It is small, it is presented as in booting preset duration, outdoor heat exchanger temperature change value is less than the first default outdoor heat exchanger temperature threshold
(for example, 3 DEG C).
When air conditioner is in refrigeration or heating mode, i.e., when air conditioner is in operational mode, when coolant circulating system is prominent
So blocking, then temperature when outdoor heat exchanger is by running is rapidly gone in preset duration close to outdoor temperature, therefore outdoor is changed
Hot device temperature change value is larger.So as to be greater than the second default outdoor heat exchanger temperature in the temperature change value of outdoor heat exchanger
When threshold value, judgement meets blocking condition.
It should be noted that working as air conditioner refrigeration mode and the corresponding second default outdoor heat exchanger temperature of heating mode
Spending threshold value can be different, can also be identical.Such as 15 DEG C can be disposed as, 16 DEG C can also be set as in heating mode,
14 DEG C are set as when refrigeration mode.

Specifically, when air conditioner is in refrigeration or refrigeration mode, when indoor heat exchanger temperature change value meets blocking item
When part, it can further judge whether the frequency change of compressor meets blocking condition.Because of indoor heat exchanger temperature change
It can be able to be since the variation of environment temperature causes that value, which is greater than threshold value,.Therefore, then the frequency change of compressor is obtained, works as compression
The frequency change of machine is greater than predeterminated frequency change threshold, i.e. air conditioner has increased operation power, and the temperature of indoor heat exchanger
