Abstract

Currently, the main operating heat and cooling storage technologies are all single-function energy storage technologies, which are inhibited from large-scale application in urban buildings due to factors such as space occupation in distributed buildings. Therefore, based on the background of "double carbon" target, this paper constructs a compact latent heating and cooling system based on the study of devices and materials for phase change heating and cooling storage. In this paper, the volume configuration of PCM is optimized by selecting sugar alcohol material with low phase change temperature and high phase change enthalpy as PCM and combining heating and cooling storage technologies to reduce the volume of thermal storage materials by 39.72% without affecting the heating capacity. Under the policy of peak-valley electricity tariff, this paper uses the Life Cycle Cost (LCC) method to prove the economy of the system. The use of the heating and cooling storage system proposed in this paper can reduce electricity expenses by about 34.36% in the heating season and 49.51% in the cooling season. By comparing the LCC of the system, the LCC of CLHCS is only 77.5% of the system without energy storage.
