Material.
The course of work of above-mentioned pressure-bearing phase-change energy-storage units is as follows：
Heat-accumulating process：Multi-layer spiral coiled 1 is formed by 6 layers altogether, first layer connect with layer 6 be first group, the second layer with
Layer 5 series connection is second group, and it is third group that third layer is connected with the 4th layer, and thermal medium (including hot water, deep fat, hot steam) is logical
It crosses water inlet 6 and enters this three groups of channels, exchange heat with phase-changing energy storage material 2, due to the basic phase of operation length of above three groups of runners
Also of substantially equal Deng the resistance of, pipe, assignment of traffic of the hot fluid when flowing through different groups of runner is uniform so that often circle coil pipe with
Material can carry out sufficient heat exchange, therefore improve the heat exchanger effectiveness of entire unit.In heat-accumulating process, phase-change accumulation energy
2 material of material becomes liquid phase, material volume expansion from solid phase, and liquid level rises, and the pressure in pressure-bearing inner liner closed chamber gradually rises,
Until regenerator temperature reaches the upper limit value of phase-changing energy storage material 2, heat-accumulating process terminates.
