The invention discloses a photovoltaic heating system based on cross-season heat storage. The photovoltaic heating system comprises a photovoltaic photo-thermal plate, a short-term heat storage watertank, a plate heat exchanger, a cross-season heat storage water tank and heating terminal equipment, a first heat exchange coil pipe is arranged in the short-term heat storage water tank, the photovoltaic photo-thermal plate is connected with the heat source side of the first heat exchange coil pipe through a heat collection circulation pipeline, the heat source side of the plate heat exchanger isconnected with the heat exchange side of the first heat exchange coil pipe through a first heat exchange pipeline, a second heat exchange coil pipe is arranged in the cross-season heat storage watertank, a second heat exchange pipeline is arranged between the heat exchange side of the plate heat exchanger and the heat source side of the second heat exchange coil pipe, and the heat exchange sideof the second heat exchange coil pipe is connected with the heating terminal equipment through a pipeline. The photovoltaic heating system has the advantages that the energy in a non-heating period isstored to be used in a heating period, natural resources are utilized according to actual conditions during actual use of the heating period, the use of storage resources is reduced, and sufficiencyof the storage resource is ensured.
Description
technical field [0001] The invention relates to the technical field of heating, in particular to a photovoltaic heating system based on cross-season heat storage. Background technique [0002] Since photovoltaic thermal panels produce hot water all year round, the amount of hot water produced in summer is the largest, while heating in winter requires a lot of hot water. How to store hot water in other seasons for heating in winter is of great significance. Using cross-seasonal storage Thermal technology is a necessary means to solve this problem. Due to the limited fluctuations that the power grid can accommodate, if the magnitude is too large, the power grid will also be affected, and the power of photovoltaic power generation is constantly changing due to the impact of solar fluctuations, so the phenomenon of power abandonment and power limit may occur in the photovoltaic power generation system, resulting in The generated electricity cannot be smoothly connected to the g...
