HEAT-STORAGE-EXCHANGE-HEATING DEVICE

摘要

A thermal storage and exchange heating apparatus (100) of the present invention includes: a thermal storage tank (3) that stores a heated heat medium; a circulation channel (4) connected to a high-temperature side and a low-temperature side of the thermal storage tank (3), and through which the heat medium circulates; a heat exchanger (5) provided to the circulation channel (4) and configured to exchange heat between the heat medium and a heating object and to heat the heating object; circulation direction switching means (17 configured to switch circulation of the heat medium in the circulation channel (4) between a forward direction from the high-temperature side to the low-temperature side of the thermal storage tank (3) and a backward direction from the low-temperature side to the high-temperature side of the thermal storage tank (3); and control means (30) configured to cause the heat medium to circulate in the forward direction set by switching of the circulation direction switching means (17) in a heating operation of the heating object and causing the heat medium to circulate in the backward direction set by switching of the circulation direction switching means (17) after a stop of the heating operation of the heating object.
