Large air conditioner, inverter air conditioner external control board, temperature sensor connected VI sampling voltage is not 2.5V, but 1\/4 power supply voltage, which is 1.25V, in fact, there is a method to determine the thermistor resistance is particularly simple, Choose a 50k potentiometer and a thermistor universal plug. For convenience, you can connect with long wires. Unplug the suspected thermistor, plug in the universal plug, energize the air conditioner, and test the potentiometer with the multimeter 5v. The voltage of the terminal slowly turns the potentiometer handle. When the voltage is 2.5V, the rotation stops. At this time, the resistance of the potentiometer is the resistance of the thermistor. For example, if the resistance is 8k and the ambient temperature is about 30\u00b0C, then the temperature sensor has a resistance of 10k.<\/p>\n\n\n\n

How to judge the quality of the air conditioner temperature sensor<\/strong><\/p>\n\n\n\n

If the air conditioner temperature sensor is broken, the following phenomena will occur, and the air conditioner temperature sensor can be judged by this:<\/p>\n\n\n\n

1. The indoor ring temperature sensor has a large resistance value, causing the air conditioner to start frequently.<\/p>\n\n\n\n

2. The resistance of the indoor tube temperature sensor becomes smaller, which causes the whole machine to be protected soon after starting.<\/p>\n\n\n\n

3. The indoor temperature and temperature of the pipe are changed, causing the air conditioner to malfunction.<\/p>\n\n\n\n

4. The indoor tube temperature change value is 0 \u03a9, which causes the whole machine to start remotely without reaction.<\/p>\n\n\n\n

Solution When <\/strong>Air conditioning temperature sensor is bad:<\/strong><\/p>\n\n\n\n

The temperature sensor barrier has a relatively large proportion in air conditioning faults. To accurately determine the function, the air conditioning control section has three temperature sensors:<\/p>\n\n\n\n

1. Room temperature sensor: mainly detects the indoor temperature. When the indoor temperature reaches the set requirement, the internal and external machines are controlled. When the cooling is stopped, the external machine stops, and the internal machine continues to run.<\/p>\n\n\n\n

2. Indoor tube temperature sensor: It mainly detects the coil temperature of the indoor evaporator, and prevents cold air, anti-overheat protection and temperature automatic control during heating.<\/p>\n\n\n\n

3. Outdoor defrosting temperature sensor: mainly detects the outdoor condenser coil temperature. When the outdoor coil temperature is lower than -6 degrees Celsius for 2 minutes, the internal machine turns into a defrosting state, when the outdoor coil sensor resistance is too large The indoor unit does not work properly.<\/p>\n\n\n\n

Analysis of the reason why the air conditioner display temperature is inconsistent with the actual perceived temperature:<\/strong><\/p>\n\n\n\n

1. The remote control setting is incorrect;<\/p>\n\n\n\n

2. The filter is not cleaned in time;<\/p>\n\n\n\n

3. There are items in the air inlet and outlet of the air conditioner that affect the heating effect. The room has a heat source or many indoor personnel, resulting in poor cooling effect;<\/p>\n\n\n\n
