在能源管理和能源消耗方面，冷藏仓库的效率如何？节约能源的机会在哪里？意识到工厂之间的巨大差异，例如，一些仍在运行的工厂早在1890年就建成了，用木屑隔热，并用通过天花板盘管循环的盐水制冷，空气/制冷剂温差低至2°F（1°C），与今天使用合成绝缘材料建造的、配备空气/制冷剂温差有时超过20华氏度（11摄氏度）的空气装置相比，人们可能会认为经济性的可能性会有很大差异。有趣的是，虽然实际节省的千瓦时可能确实不同，但工作的基本原则是相同的。 每一家工厂都可能通过原始设计的差异提供另一家无法获得的独特机会。能源是一个管理问题，但更确切地说，能源是一个管理机会。引文:俄亥俄州辛辛那提ASHRAE学报第87卷第2部分研讨会

How effective is a cold storage warehouse in terms of energy management and consumption of energy resources, and where do the opportunities lie for conservation?Realizing that plants differ greatly, e.g., some still in operation were built as long ago as 1890 and were insulated with wood chips and refrigerated with brine circulated through ceiling pipe coils with air/refrigerant temperature differences as low as 2°F (1°C), compared to a plant built today using synthetic insulations and equipped with air units operating with air/refrigerant differential temperatures of sometimes over 20°F (11°C), one might assume the chances for economies would vary by a great extent. The interesting fact is that while the actual kWh savings may indeed differ, the basic principles at work are the same. Each plant may offer, through differences in original design, a unique opportunity not available to the other.Energy is a management problem,but perhaps better stated -- energy is a management opportunity.
