Land-saving type solar cross-seasonal heat accumulation pond

Abstract

The invention discloses a land-saving type solar cross-seasonal heat accumulation pond. The heat accumulation pond is an enclosed space which is composed of a bottom, a side wall and a top. The enclosed space is filled with a heat accumulation solid stacked bed. A hot well and a cold well are arranged inside the heat accumulation pond. A heat using side submerged pump and a heat source side submerged pump are arranged inside the hot well. The heat using side submerged pump and a heat using side (namely a heat using user, a heat using side intake pipe and a heat using side return pipe) constitute a heat using side circulation system. The heat using side intake pipe is connected with the heat using side submerged pump in the hot well and the heat using side, and the heat using side return pipe is connected with the heat using side and the cold well. The heat source side submerged pump and a heat source side (namely a solar thermal collector or other heat supply sources, a heat source side intake pipe and a heat source side return pipe) constitute a heat source side circulation system. The heat source side intake pipe is connected with the cold well and the heat source side, and the heat source side return pipe is connected with the heat source side and the heat source side submerged pump in the hot well.

Description

technical field [0001] The invention relates to a solar heating system. Background technique [0002] Solar energy is an inexhaustible renewable energy source. Today, as fossil fuels are decreasing year by year and the international energy situation is becoming increasingly severe, the development and utilization of solar energy is one of the important ways to realize the diversification of energy supply and ensure energy security. Solar heating is one of the effective ways to reduce the heating coal consumption of buildings in northern my country. For urban residential buildings, due to the small building shape coefficient and the small area of ​​the building body for placing solar collectors, it is impossible to realize solar building integration like a single building in a village or town. According to relevant research, concentrated solar heating system is one of the low-carbon heating systems more suitable for urban buildings. The concentrated solar heating system inc...
