浙江省嘉善县自1975年开始研制平板集热器,79年参加了在西安举行的全国第二次太阳能利用经验交流会,会议期间对全国各地17个单位(包括一些研究所、大学)送展的19台热水器组织了统一测试,结果嘉善县送展的二台 G Y—I 型平板热水器样品在系统日效率和温升方面名列前茅,获得一致好评。该厂在 G Y—I 型热水器基础上改进研制而成的 PYG2.O—Ⅲ型太阳能热水器,最近通过了有关部门的鉴定。该产品光效率高
Jiashan County, Zhejiang Province has been developing flat-panel collectors since 1975, and participated in the second national solar energy utilization experience exchange meeting held in Xi’an in 1979. During the meeting, 17 units (including some research institutes and universities) across the country were presented Of the 19 water heaters organized a unified test, the results sent to Jiashan County, two sets of GY-I flat water heater samples in the system efficiency and temperature rise among the best, was unanimously praised. The plant in the G Y-I-based water heater developed on the basis of PYG2.O-Ⅲ-type solar water heaters, recently passed the identification of relevant departments. The product is light-efficient
