Abstract

The commercial sector in Europe consumes a lot of energy and has one of the highest rates of energy consumption in supermarkets. Thus, supermarkets are an important part for the purposes of meeting the targets for reducing greenhouse gases which Europe has set as 10% by 2020. This article discusses the potential of economic and energy consumption savings in addition to the reduction in greenhouse gases that a high energy efficiency air conditioning installation can have in supermarkets. An analysis of the air conditioning installation is carried out in a commercial infrastructure considered as a model. Exploring the way energy is used at different times of the year and comparing the results obtained from a traditional duct installation and a high energy efficiency installation. High energy efficiency installation uses inverter technology and energetically takes advantage of the residual heat from industrial cooling processes. When high energy efficiency system is used for supermarket air conditioning, the savings in electricity consumption vary between 56 and 62%, reducing CO₂ emissions to less than half with a payback period in high energy efficiency installation of three-to-four years and this reduces the ecological footprint of the products sold in supermarkets.

在超市中使用高能效HVAC改善经济和环境

摘要

欧洲的商业部门消耗大量能源，是超级市场中能源消耗率最高的国家之一。因此，超级市场是实现欧洲到2020年将温室气体减少10％的目标的重要组成部分。本文讨论了在减少温室气体排放的同时，还可以节省经济和能源消耗的潜力超级市场可以安装节能空调。在作为模型的商业基础设施中对空调安装进行了分析。探索一年中不同时间使用能源的方式，并比较从传统风道安装和高能效安装获得的结果。高能效设备使用逆变器技术，并充分利用了工业冷却过程中产生的余热。当将高能效系统用于超市空调时，节省的电量在56％至62％之间，从而减少了CO₂排放量不到一半，在高能源效率的安装三到四年的投资回收期，这降低了超市销售的产品的生态足迹。
