“双碳”目标下可再生能源与常规冷热源系统的耦合应用与运行模式分析

Coupling application and operation mode analysis of renewable energy and conventional cold and heat source systems under“dual carbon”target

为了解决热泵系统存在的初投资高、产热波动大等问题,提出将空气源热泵系统与常规冷热源系统耦合。分析了计算耦合系统空气源热泵装机比值的3个维度、并联连接和串联连接2种方式的运行模式,给出了耦合系统的供回水温度建议。

In order to solve the problems of high initial investment and large fluctuations in heat generation in heat pump systems,it is proposed to couple air-source heat pump systems with conventional cold and heat source systems.In this paper,three dimensions for calculating the installed ratio of air-source heat pumps in coupling systems and two operation modes of parallel and series connections are analysed,and the recommendations for the supply and return water temperatures of the coupling system are provided.
