[填空题]
A dehumidifier is essentially a “refrigerator with an open doo24d tx) koo0wca:4gq m,wgty.r.” The humi(fap, de- x py*2aosw f2w6kl9d air is pulled in by a fan and guided to a cold coil, where the temperature is less than the dew point, and some of the air’s water condenses. After this water is extracted, the air*y6f ,2laxwk2o(ef9pa w pd s- is warmed back to its original temperature and sent into the room. In a well-designed dehumidifier, the heat is exchanged between the incoming and outgoing air. This way the heat that is removed by the refrigerator coil mostly comes from the condensation of water vapor to liquid. Estimate how much water is removed in 1.0 h by an ideal dehumidifier, if the temperature of the room is 25$^{\circ}\,C$, the water condenses at 8$^{\circ}\,C$, and the dehumidifier does work at the rate of 600 W of electrical power. kg
