摘要
在“双碳”背景下,综合能源系统不断地推进可再生能源灵活消纳、低碳化供热供冷、工业余热利用及配合电网灵活调峰等领域的技术改革。热泵因具有高效率、低污染的特点,在综合能源系统中得到广泛应用。热泵可作为系统的供能及储能单元。在综合能源系统中,以能量来源为依据,热泵被分为空气源、水源、土壤源及余热4类,对作为供能单元的4种热泵分别进行描述;按照储能类型,热泵可被分为储热(冷)及储电2种。热泵的使用实现了综合能源系统的低碳化及高效化运行,但在其应用过程中存在能源匹配以及优化运行等方面的问题。最后,对热泵在综合能源系统中的发展趋势进行了展望。
In the context of"dual carbon",integrated energy systems are continuously promoting the technological reforms in the fields of flexible renewable energy consumption,low-carbon heating and cooling,industrial waste heat utilization and flexible and coordinated peak shaving for the power grid.Heat pumps are widely used in integrated energy systems because of their high efficiency and low pollutant emissions.Being the energy supply or energy storage unit in an integrated energy system,heat pumps can be divided into four categories according to their energy sources,air source,water source,soil source and waste heat recovery heat pumps.Heat pumps can be heat(cold)storage and electricity storage units according to their functions.Heat pumps can facilitate the low-carbon and high-efficiency operation of the system,but arise problems from energy coupling and optimal operation.Finally,the development trend of heat pumps in integrated energy systems is prospected.
