蓄热式室内游泳池的热负荷分析与计算

Calculation and Analysis of the Heat Loads of Indoor Swimming Pool with Heat Storage System

现今运行的直接加热的室内游泳池多使用燃煤锅炉,结果造成环境污染,若使用电锅炉,则造成电网峰谷差增大.解决这一矛盾的较合理的方法是使用电锅炉蓄热的方式.蓄热式室内游泳池的热负荷是热系统设计的基础,热负荷的分析计算也是其经济运行的要求.通过分析蓄热式室内游泳池的热负荷构成,将其划分为开放释热和关闭蓄热两个时段.其中开放释热时段包括池水系统热负荷、运行设备的散热损失、通风系统热负荷、围护构件的热损失、淋浴室的热负荷与人体散热量计算等;而关闭蓄热时段热负荷主要由三部分构成,即池面的蒸发散热、池面与室内空气的对流散热以及池壁的导热.文章分别给出了每一时段的各项热负荷计算公式.

Coal boilers,which are widely used in direct heating systems in the indoor swimming pool, cause environment pollution, and electric boilers may result in the large peak-valley value to the electric power network.Using the heat storage system with electric boiler is a suitable way to solve these problems. Heat loads are the thermal system design foundations to the indoor swimming pool with heat storage system. The heat loads are divided into two periods:the heat release in opening and the heat storage in closing period, respectively. In the heat release period, the heat loads of the pool water system include the loads of the running equipments, the ventilation system, the surround components, the shower bath and clays. In the period of closing, the heat loads are consisted of three parts. The first is the heat lose by vaporizing from the pool surface; the second is the convectional heat lose between the pool surface and the room air; the last is the heat lose conducted by the pool wall. The computation formulas to each kind of the heat loads are presented.
