Solar cross-season heat-storage heating system

Abstract

The invention relates to a solar cross-season heat-storage heating system which comprises a solar collector, a heating tail end, a layered water tank, an underground heat storage region and an auxiliary heat source, wherein a water supply pipe of the collector is connected with a high-temperature region of the layered water tank through a first electromagnetic valve, a first circulating water pump is arranged on a water return pipe of the collector, and the water return pipe of the collector is connected with a low-temperature region of the layered water tank; the low-temperature region of the layered water tank is connected with the underground heat storage region through a second circulating pump, and the water supply pipe of the collector and the low-temperature region of the layered water tank are provided with a communicating pipe and equipped with a second electromagnetic valve; the water supply pipe at the heating tail end is connected with the first electromagnetic valve, the high-temperature region of the layered water tank and the underground heat storage region through a third circulating water pump, and the water return pipe at the heating tail end is connected with the low-temperature region of the layered water tank; and the water supply pipe of the auxiliary heat source is connected with the high-temperature region of the layered water tank and the water return pipe of the auxiliary heat source through a fourth circulating water pump for constituting a heating season trough electric heat storage system. The solar cross-season heat-storage heating system uses solar energy as main energy input and can meet the 24-hour heating needs of a building by using cross-season heat storage / heat release for balancing the seasonal peak / trough distribution of the solar energy.

Description

technical field The invention relates to the technical field of high-efficiency utilization of renewable energy, in particular to a solar energy interseasonal thermal storage heating system. Background technique With the development of social economy and the improvement of people's living standards, the total energy consumption for heating and air conditioning is increasing. At present, heating energy consumption in the north accounts for 25% of my country's total building energy consumption, and there is a trend of increasing year by year, which will put a huge pressure on my country's energy supply. my country's traditional heating system is composed of heat sources (such as coal-fired boilers, gas oil boilers, thermal power plants, etc.), heating networks and indoor heating systems. In the long-term operation, there are the following problems: first, the energy consumption of heating in my country is too high; second, the use of high potential energy (such as coal, gas, ...
