我们自行设计和研制的一台新型间歇式太阳能制冰机,效果较好。已于1977年7月通过了鉴定,并于1979年9月参加了全国第二次太阳能利用经验交流会的展出。这台样机的主要特点是:能够利用多种能源,有多种用途,结构紧凑,移动和操作简便,制冰效果好,效率比较高。现将经过改进的间歇式太阳能制冰机概要介绍如下(图3)。为了在白天发生阶段能够利用多种能源,例如利用锅炉余热、废气或地热等,以便保证发生的氨量,也就是保证制冰量的稳定性,在直径3.2厘米的集热管内套有直径1.0厘米的细管,而在直径15.9 We design and develop a new type of intermittent solar ice machine, the better. In July 1977 passed the appraisal, and in September 1979 participated in the country’s second solar energy utilization experience exchange exhibition. The main features of this prototype are: to use a variety of energy sources, a variety of uses, compact structure, easy to move and easy to operate, good ice making effect and high efficiency. An improved intermittent solar ice maker is now outlined below (Figure 3). In order to be able to use a variety of energy sources in the daytime phase, such as the use of boiler waste heat, exhaust gas or geothermal, etc., in order to ensure the occurrence of ammonia, which is to ensure the stability of the ice volume, diameter of 3.2 cm collector tube diameter 1.0 Thin tubes of centimeters, while at a diameter of 15.9
