| 摘 要： | 太阳能-热泵除湿机-微计算机监控(TRCW)联合干燥系统中,木材干燥室的供热与湿空气的排湿,由太阳能供热系统和热泵除湿机两者配合起来完成。整个联合干燥系统的工作过程由微机监控系统来实现自动控制。太阳能集热器为平板式空气型,采光面积为75m~2,,热泵除湿干燥机按压缩式制冷循环工作(压缩机功率为3.75kW),以热泵供热的方式供给木材干燥所需的热量,而以制冷除湿方式除去木材蒸发到空气中的水分。联合系统的干燥能力为15～25m~3木材,在1989年4月至1990年7月的实验中,干燥的材种有水曲柳、柞木、榆木、红松、白松等。木材板厚为3～6cm,初含水率40％～60％,终含水率8.5％～15％,年平均干燥能耗每m~3木材为80kW·h及每kg水为0.53kW·h。

A Study of the Combination System for Lumber Drying |

| Abstract: | In the study, heating in the kiln and dehydrating from moist air were carried out by a solar heating system in conjunction with a heat pump dehumidifier. The entire process was controlled by microcomputer. The solar collecter was a flat plate air tube being 75 squared metres sunshine area. The heat pump worked by compressing refrigerated circulation (compression power 3.75kW). The calorific requirement for lumber drying was supplied by the heat pump, and the moisture evaporated from lumber was removed by means of refrigeration-dehydration. The drying capacity of this system was 15～25m~3. In the tests from April, 1989 to July, 1990, the lumber dried was 3～6cm thick with 40％～60％ first moisture content and 8.5％～15％ final MC. The species included Pinus koraiensis, Picea spp., Quercus spp., Ulmus spp., Fraxinus mandshurica, etc. The average pure electrical energy consumption was 80kW·h per m~3 lumber or 0.53kW·h per kg water a year. |
