摘　　要：电驱动热泵技术在为建筑提供清洁冷热的同时,也成为了与电网协同、消纳清洁电力的关键环节。本文以电驱动热泵技术为核心,冬季供热采用中深层地埋管提供高品位低温热源,夏季供冷结合冷却塔技术构建高效冷热供应系统。在此基础上结合用户侧蓄能技术,实现日间冷热蓄存,同时以充分消纳本场光伏发电及市政清洁电力为目标提出了系统的设计方法与运行控制策略。随后以我国某大型公共建筑为例开展了定量分析,以明确其实际节能减排效果。The electric-driven heat pump technology is commonly applied for space heating and cooling for buildings,and also becomes the key link for cooperation with power grid to consume clean electricity.This paper proposes a high-efficiency heating and cooling system by combining the electric-driven heat pump technology with the medium-depth ground heat exchanger for heating in winter and the cooling tower for cooling in summer.Then the user-side energy storage system is applied for daily heat and cool storage.With this system,the design method and control strategy are proposed to fully absorb the local photovoltaic power generation and municipal clean power.Furthermore,this paper conducts a case study on a large public building with quantitative analysis,so as to analyse the actual energy-saving and CO 2 emission reduction effect.
