Dehumidifier with compensation and controlling method thereof

A dehumidifier with compensation, comprising:

• an environment-adjusting device, adjusting an indoor space according to a target humidity value;
• a temperature-detection unit, detecting a plurality of simultaneous temperature values of the indoor space;
• a humidity-detection unit, detecting a plurality of simultaneous humidity values of the indoor space;
• a temperature-compensation unit, deriving a plurality of compensated temperature values by calculating and/or checking a temperature reference table according to the plurality of simultaneous temperature values and the plurality of simultaneous humidity values;
• a control unit, adjusting a power of the environment-adjusting device according to the plurality of compensated temperature values and the target humidity value, to shorten a time achieving to the target humidity value;
• and
• at least one heat-generating unit, comprising the environment-adjusting device and generating a waste heat.
