Heating system capable of storing energy by combining photo-isomerized material and thermal-isomerized material and method for applying heating system to heating

Abstract

The invention relates to a heating system capable of storing energy by combining a photo-isomerized material and a thermal-isomerized material. The heating system comprises at least one heat exchanger, a solar energy storage heat exchange loop system and an off-peak electricity energy storage heat exchange loop system. The heat exchangers communicate with a cold / hot water pipeline of a heating pipeline of a user so as to form a water circulation loop. The solar energy storage heat exchange loop system and the off-peak electricity energy storage heat exchange loop system are arranged in parallel. The solar energy storage heat exchange loop system and the off-peak electricity energy storage heat exchange loop system are each in series connection with at least one heat exchanger. The heatingsystem can solve the problem of instability and discontinuity of energy by providing stored energy for the photo-isomerized material through solar energy and providing stored energy for the thermal-isomerized material through off-peak electric heating, wherein the photo-isomerized material and the thermal-isomerized material can be both stored at normal temperature, and the requirement for the heat preservation performance of equipment is low.

Description

technical field [0001] The invention relates to the field of energy storage devices, in particular to a heating system for energy storage combined with photoisomeric materials and thermal heterogeneous materials and a heating method thereof. Background technique [0002] Since the 20th century, social productivity and people's living standards have developed by leaps and bounds. As one of the basic industries of the national economy, the electric power industry has made great progress. However, the growth of electricity still cannot meet the rapid development of the national economy and the sharp increase in people's daily electricity consumption. The situation of partial electricity shortage in the whole country still exists, and the contradiction of insufficient supply of electricity in peak peaks and excess in troughs has become increasingly prominent. [0003] To solve the problem of power shortage, on the one hand, it is to increase investment in power, speed up the pac...

Problems solved by technology

Latent heat storage is to use the phase change of materials to absorb heat to store energy. The heat storage density of materials per unit mass is generally higher than that of sensible heat materials, but latent heat materials do not have fluidity, and the heat storage modules are relatively complicated, with high equipment investment and economic benefits. Low

In addition, both sensible heat and latent heat materials need to be efficiently insulated, which increases the investment cost of the system

Although there are optical energy storage materials in the prior art, there is no precedent for applying them to heating systems
