Abstract

The invention relates to an energy-storage heat exchange device. The energy-storage heat exchange device comprises an energy storage pile, a heat exchanger, a heating tube and a fan, wherein a thermal insulation layer A is arranged at the periphery of the energy storage pile; a gap between the energy storage pile and the thermal insulation layer A is taken as an air flue; a ventilating groove is formed in the energy storage pile; the fan is connected with the heat exchanger through a pipeline; the other end of the fan is accessed into the air flue A through a pipeline; the other end of the heat exchanger is accessed into an air flue B through a pipeline; the air flue A and the air flue B refer to air flues formed between opposite two ends in the energy storage pile and the thermal insulation layer A; an electric heating tube is arranged in the energy storage pile in a penetrating mode for heating the energy storage pile; under driving of the fan, air flow enters the energy storage pile through the air flue A; and air flow is heated by the energy storage pile. The energy-storage heat exchange device utilizes off-peak electricity to heat the energy storage pile, and utilizes the energy storage pile to slowly release heat for heating air flow to form hot air; and after entering the heat exchanger to exchange heat, hot air is changed into cold air for being blown into the fan, and re-enters the air flue A under driving of the fan in a circulating mode, so that the energy-storage heat exchange purpose is realized.

Description

technical field

[0001] The invention belongs to the field of phase change energy storage and energy exchange, and relates to an energy storage heat exchange device. Background technique

[0002] At present, building heating and industrial and agricultural heating consume a large amount of high-quality energy such as fossil energy and electricity, and also produce a large amount of carbon dioxide and other pollutants. Therefore, in response to the national call for energy conservation, emission reduction and energy renewable utilization, it is necessary to develop and utilize cheap renewable energy for building heating and industrial and agricultural thermal insulation heating technology.

[0003] Off-peak electricity is a cheap energy source encouraged by the state. However, due to time problems, off-peak electricity is often not fully utilized, and it is more and more widely used in building heating and industrial and agricultural heating. In order to store heat, people ha...
