Method and device for heating by heat electric heating pump phase-change thermal storage

Abstract

Disclosed is a thermoelectric heat pump phase change heat storage heating method and a device. When in energized heat storage during the trough electrovalency phase, the thermoelectric chip set is connected with one end of the phase change heat storage materials as the fire end, and the heat energy generated is transferred to the phase change heat storage materials for storage, while the other end of the thermoelectric chip set becomes the cool end and adsorbs the waste heat from the surrounding air. When in heat emission heating, there is provided with two working modes, the first working mode is an energy saving mode, wherein the surrounding air directly exchange the heat with the regenerative phase change heat storage materials to realize the heat release warm; when the first working mode can not satisfy the warm request, the current direction of the thermoelectric chip set is changed, to make the cold and heat end faces changed; one end of the thermoelectric chip set connected with the phase change heat storage materials becomes the cold end, which adsorbs the heat energy of the phase change heat storage materials, and the heat of the other end of the thermoelectric chip set is released for the warm.

Description

technical field [0001] The invention belongs to the technical field of energy heating, and in particular relates to a thermoelectric heat pump phase change heat storage heating method and device. Background technique [0002] With the improvement of people's living standards, more and more electrical appliances have entered the homes of ordinary people, and the frequency of use of most of these electrical appliances has dropped after the early morning, which makes the originally very serious "peak-valley" contradiction of power supply more prominent , the difference between peak power consumption and valley load is getting bigger and bigger. In recent years, as the winter temperature has continued to drop, especially during the period of freezing disasters, the heating load has continued to rise. In some cities, the peak load in winter exceeds the peak load in summer, and frequent power cuts have occurred in various provinces and regions. Heat storage technology can "evenly...
