no. 1 Embodiment

[0042] The first specific embodiment: After the compressor 12 runs stably, the outdoor ambient temperature is 35 degrees Celsius, the indoor ambient temperature is 27 degrees Celsius, and when the indoor set temperature is 25 degrees Celsius, that is, the compressor operates under nominal cooling conditions, set the first The first threshold is 10 degrees, assuming that the outdoor ambient temperature is T1 and the temperature of the exhaust port measured by the compressor temperature sensor is T2:

[0043] When T2-T1≥10, it is determined that the temperature sensing package has not fallen off and the temperature measurement is normal;

[0044] When T2-T1<10, it is judged that the temperature sensing package has fallen off and abnormality occurs.

no. 2 Embodiment

[0045] The second specific embodiment: after the compressor runs stably, the outdoor ambient temperature is 43 degrees Celsius, the indoor ambient temperature is 32 degrees Celsius, and when the indoor set temperature is 28 degrees Celsius, that is, the compressor operates under high-temperature refrigeration conditions, set the first The threshold is 30 degrees, assuming that the outdoor ambient temperature is T1 and the temperature of the exhaust port measured by the compressor temperature sensor is T2:

[0046] When T2-T1≥10, it is determined that the temperature sensing package has not fallen off and the temperature measurement is normal;

[0047] When T2-T1<10, it is judged that the temperature sensing package has fallen off and abnormality occurs.

no. 3 Embodiment

[0048] The third specific embodiment: after the stable operation of the compressor, the outdoor ambient temperature is 39 degrees Celsius, the indoor ambient temperature is 30 degrees Celsius, and when the indoor set temperature is 29 degrees Celsius, that is, the compressor operates under general refrigeration conditions, set the first The threshold is 30 degrees, assuming that the outdoor ambient temperature is T1 and the temperature of the exhaust port measured by the compressor temperature sensor is T2:

[0049] When T2-T1≥10, it is determined that the temperature sensing package has not fallen off and the temperature measurement is normal;

[0050] When T2-T1<10, it is judged that the temperature sensing package has fallen off and abnormality occurs.

[0051] The first threshold is actually set according to the actual operating conditions of the air conditioner, which further improves the accuracy of detection of temperature sensing package falling off and avoids false al...

Abstract

The invention provides a method and device for detecting a thermal bulb of a compressor and an outdoor unit. The method for detecting the thermal bulb of the compressor includes the steps of acquiring temperature of the outdoor environment and the temperature of an exhaust port measured by the thermal bulb of the compressor, calculating the difference value between the temperature of the exhaust port and the temperature of the outdoor environment, judging whether the difference value is smaller than a first threshold, and determining the fact that the thermal bulb of the compressor drops when difference value is smaller than the first threshold. According to the technical scheme, the problem that the situation that the thermal bulb of the compressor drops can not be detected in time is solved, then prompts can be effectively given out under the situation that the thermal bulb drops, the phenomenon that the cooling effect or the heating effect of an air conditioner is reduced because the exhaust temperature of the compressor is inaccurately measured is avoided, and potential hazards of operation faults of an air conditioner unit are eliminated.

Description

technical field [0001] The invention relates to the detection field, in particular, to a detection method and detection device of a temperature sensing package of a compressor and an outdoor unit. Background technique [0002] When the compressor of the air conditioner is running, the discharge temperature of the compressor will be much higher than the outdoor ambient temperature. However, when the discharge temperature of the compressor is too high, it will affect the working stability of the compressor and the cooling or heating effect of the air conditioner. There is a temperature-sensing package, which is used to measure the discharge temperature of the compressor. When the discharge temperature exceeds the limit value, the high temperature protection will be activated. [0003] However, in the prior art, during transportation or use, the temperature-sensing package tends to be detached from the air outlet of the compressor. When the temperature sensing package falls o...
