Description

technical field [0001] The invention relates to the field of heat storage and heat supply research, in particular to a vehicle-mounted heat storage and heat supply device and a working method thereof. Background technique [0002] At present, the heating methods can be mainly divided into large-scale centralized heating network heating and small decentralized independent heating. However, these two heating methods have their own deficiencies. For example, due to the complex urban structure, the construction and renovation of centralized heating pipe networks are difficult in some areas, while the number of small regional boiler rooms is large, and the scale of renovation is relatively large. Some of them use natural gas. Users who use energy such as electricity and electricity for heating have incurred higher costs, reducing the economy of the heating system. On the other hand, industrial enterprises produce waste heat every year, and waste heat accounts for a high proporti...

Problems solved by technology

However, these two heating methods have their own deficiencies. For example, due to the complex urban structure, the construction and renovation of centralized heating pipe networks are difficult in some areas, while the number of small regional boiler rooms is large, and the scale of renovation is relatively large. Some of them use natural gas. Users who provide heat with energy such as electricity and electricity have incurred higher costs, reducing the economy of the heating system

On the other hand, industrial enterprises produce waste heat every year, which accounts for a relatively high proportion of their total energy consumption, while the recycled waste heat resources, especially the low-temperature waste heat resources below 150°C, are less, resulting in a great waste of heat energy

[0003] In response to the above problems, research and development in the field of mobile heat storage and heating has been started at home and abroad, but because it is in the preliminary stage, the following problems still need to be overcome: the existing heat storage equipment is all integrated design, and must be charged to a certain extent And the next cycle can only be executed when the heat is released to a certain extent. The charging and discharging time is long, and the energy storage per unit volume is low, and the safety performance of some energy storage materials is low. more pollution
