The invention provides a step heat storage
temperature control system and
temperature control method based on a
phase change energy storage technology, and belongs to the technical field of
phase change heat storage. According to the technical scheme, the step heat storage
temperature control system comprises a high-temperature heat source, a
solar heat collector, a normal-temperature
water source and a temperature
control system. The high-temperature heat source flows out of an
evaporator through a
waste heat pipe, an inlet and an outlet of the
evaporator are connected through a heat exchange circulating
pipe, and the heat exchange circulating
pipe is sequentially connected with a compressor, a step heat storage device and a
liquid storage tank; an inlet and an outlet of the
solar heat collector are connected through a heat collection circulating pipe, and the heat collection circulating pipe is connected with the step heat storage device. The normal-temperature
water source flows out through the step heat storage device and to-be-heated equipment through a
heat supply circulating pipe; the temperature
control system comprises a controller, a temperature control
ball valve and a temperature sensor, wherein the temperature control
ball valve and the temperature sensor are arranged on the
heat supply circulating pipe. The step heat storage temperature
control system and temperature control method based on the
phase change energy storage technology has the beneficial effects that through the heat exchange design of different temperature gradients, the storage rate of
heat energy is increased, the performance and efficiency of a phase change
energy storage device are greatly improved, the heat exchange speed of the
heat energy is increased, and the application performance of the phase change energy storage device is improved.
