农业温室供热系统的研究和设计

农业温室（以下简称温室）是具有必要设备的、能够常年为作物生长和发育提供所需条件的特殊建筑物。温室是一个特殊的生产车间，冬季要供热。结合示范工程温室的设计，着重介绍了温室的型式、覆盖材料、热负荷计算、供热系统形式以及节能运行方式等。

Research on the heating system of agricultural greenhouses and its design

An agricultural greenhouse is a special construction which is equipped with technical facilities necessary for providing conditions for the growth and development of crops. The agricultural produce such as vegetables and flowers produced in greenhouses features high yield and quality, and freedom from pollution. As a special production shop, a greenhouse needs a heating system operating in winter. In this presentation, research on the heating system of agricultural greenhouses and the design of a demonstration greenhouse were carried out. Discussed in detail were types of greenhouses, covering materials, heating load calculations, types of heating systems for agricultural greenhouses, and economical operation etc.
