Why can’t dehumidifier start normally
2015-10-22 15:21
Dehumidifier, also known as dehumidifier, can be generally divided into household dehumidifier and industrial dehumidifier, which belongs to a small member of refrigeration and air conditioning family. Generally, the dehumidifier is composed of compressor, heat exchanger, fan, water container, casing and controller. Its working principle is: the wet air is pumped into the unit by the fan, and the water in the air is condensed into water droplets through the heat exchanger, and the treated dry air is discharged from the machine, so as to reduce the indoor humidity.
Because of the improvement of people’s living standards, dehumidifiers are not only widely used in industry, but also more and more in families. However, the machine and equipment in use will always fail, dehumidifier is no exception. We have already introduced some system failures of industrial dehumidifiers. Today, we will introduce the common failures in the use of dehumidifiers. First of all, we will introduce the failures that fail to start up normally and have poor dehumidification effect, as follows: < br / >Fault phenomenon: the dehumidifier stops soon after starting up, and it can be started again after a long time, and the dehumidification effect is very poor < br / >Check the fault: < br / >&1. Whether the power cord is plugged in properly; whether the LCD indicator is on; < br / >&2. Whether the main board fuse is blown&3. Is the full water indicator always on? < br / >&4. Whether the compressor and fan start normallyMaintenance method: restore the power supply, restore the power supply, replace with a new fan motor, put the water tank again, troubleshooting.
Cause analysis: the compressor of dehumidifier is rotary compressor with poor heat resistance. The rotation speed of fan motor decreases and the air volume decreases, that is, the air volume flowing through the condenser decreases, which causes the compressor exhaust pressure to rise, resulting in the compressor overheating protection (shutdown). The overheating of the compressor can only be reduced to normal after cooling for a long time, so the compressor can be started again after cooling for a long time.
