本文探讨了通过使用数据中心作为温室生产的热源来提高瑞典北方在纬度65度的粮食供应自给自足程度的可能性。采用动态建筑能耗模拟软件，计算了一个1 MW数据中心一年内每小时的排风量，以及两种不同温室规模（2000 m2和10000 m2）和两种不同生产情景下的相应采暖需求。部分年份生产，1 Mars -10月15日，无生长灯，全年生产有生长灯。该研究表明，1兆瓦数据中心的电力输入的5.5-30.5%可以回收。2000 m2温室基本上可以完全利用余热（89.7- 97.9%），而10000 m2温室全年和部分年份的供热需求仅能满足50.0-61.5%。结果表明，10000 m2温室全年生产是最突出的情况，其经济效益将达到瑞典北方蔬菜自给率的7.6%。充足性
This paper examines the possibility of increasing Northern Sweden’s degree of self-sufficiency in food supply, at the 65th latitude, by using a data center as a heating source for greenhouse production. A dynamic building energy simulation software was used to compute both the hourly exhaust air output from a 1 MW data center for one year and the corresponding heating demand for two different greenhouse sizes, 2000 m2and 10 000 m2, and two different production scenarios. Partial year production, 1 Mars – 15 October, without grow lights and full-year production with grow lights. The study showed that 5.5–30.5% of the electrical input to a 1 MW data center could be recovered. The 2000 m2greenhouse could operate almost entirely, 89.7–97.9%, on excess heat while only 50.0–61.5% of the 10 000 m2greenhouse heating demand could be met for full- and partial-year production, respectively.Furthermore, it is concluded that the 10 000 m2greenhouse with full year production was the most prominent case and would cost-effectively yield 7.6% of northern Sweden’s vegetable self-sufficiency.
