    If a 75.53m~2 flat-plate solar collector is used on combination with a solar-heat pump dehumidifier for lumber drying durig a sunny day without strong wind during the period from April to November in Beijing, the air temperature would be raised to 40 to 70℃. The average quantity of heat from the solar collectors was 14~25kw. The power consumption of the centrifugul blowers was 2.5kw. Total energy consumption were cut down by 20 percent or more by using solar energy. When only solar energy was used for drying...

    If a 75.53m~2 flat-plate solar collector is used on combination with a solar-heat pump dehumidifier for lumber drying durig a sunny day without strong wind during the period from April to November in Beijing, the air temperature would be raised to 40 to 70℃. The average quantity of heat from the solar collectors was 14~25kw. The power consumption of the centrifugul blowers was 2.5kw. Total energy consumption were cut down by 20 percent or more by using solar energy. When only solar energy was used for drying 15m~3 of 5cm thick Pinus koracensis in August, 1989, moisture content was lowered from 31% to 14.4% in 12 days, and the electrical energy consumed was 19.6kw·h/m~3.
