Problems solved by technology
If the temperature sensing package falls off, the temperature of the coil cannot be detected, which will cause the temperature of the indoor heat exchanger to be too high when the air conditioner is heating or the temperature of the indoor heat exchanger to be too low when the air conditioner is cooling, resulting in frosting, thus damaging the refrigeration system of the air conditioner

The invention discloses an air conditioner indoor unit and a detection method for a temperature sensing bulb of the air conditioner indoor unit. The air conditioner indoor unit comprises an indoor heat exchanger, a temperature sensor, the temperature sensing bulb and a processor; the indoor heat exchanger comprises a coil pipe; the temperature sensor is used for detecting the indoor environment temperature; the temperature sensing bulb is arranged on the coil pipe and used for detecting the temperature of the coil pipe; the processor is connected with the temperature sensor and the temperature sensing bulb and used for calculating an absolute value of a difference value between the indoor environment temperature and the temperature detected by the temperature sensing bulb, judging whether the absolute value is smaller than a set threshold value, determining that the temperature sensing bulb falls off when the absolute value is smaller than the set threshold value and transmitting an alarming signal. According to the air conditioner indoor unit, a user can be reminded to turn off an air conditioner after the temperature sensing bulb of the indoor heat exchanger falls off, and therefore a refrigerating system of the air conditioner is protected.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner indoor unit and a temperature sensing package detection method of the air conditioner indoor unit. Background technique [0002] The temperature sensing package on the coil of the indoor heat exchanger of the air conditioner indoor unit is used to detect the temperature of the coil of the indoor heat exchanger when the air conditioner indoor unit is running, and the air conditioner indoor unit judges whether the indoor heat exchanger is running according to the temperature of the coil normal. If the temperature-sensing package falls off, the temperature of the coil cannot be detected, causing the temperature of the indoor heat exchanger to be too high when the air conditioner is heating or the temperature of the indoor heat exchanger to be too low when the air conditioner is cooling, resulting in frosting, thus damaging the refrigeration system of the ...
