Abstract

The invention relates to a cross-season and short-term heat storage combined solar heating system and a control method thereof, and relates to the field of solar heat utilization and heat storage. Thedevice comprises a solar heat collector, a short-term heat storage water tank, a cross-season heat storage water tank, a water source heat pump, a plate heat exchanger, a radiation heat dissipation device, a valve, a water pump and a control system. The short-term heat storage pool can provide a stable heat source for a cross-season heat storage pool, and the loss of frequent starting and stopping of the heat storage circulating water pump in the prior art is reduced; when the water temperature in the heating middle-and-later-period cross-season heat accumulation water tank is low, and heat is radiated from the short-term heat storage pool to the tail end radiation heat dissipation device. The solar heating system can adapt to the water temperature conditions of different heat storage tanks and perform various working modes, the control method of the solar heating system cooperates with different heat taking forms, and heat supply of the heat supply system cooperates with heat requirement of users. According to the solar heating system, the operation can be automatically controlled, the heat supply requirements of the users can be met, the solar heat supply guarantee rate and thesolar energy utilization rate are improved, and the energy consumption of the auxiliary heat source is reduced.

Description

technical field [0001] The invention relates to the technical field of solar heat utilization and heat storage, in particular to a solar heating system combined with cross-season and short-term heat storage and a control method thereof. Background technique [0002] Solar energy is a renewable and clean energy source. If it is used as a heat source for heating systems, it will have significant energy-saving and environmental protection benefits. However, solar energy has a seasonal imbalance, and solar heat supply has the contradiction of "insufficient in winter and excess in summer". Cross-seasonal heat storage technology stores solar energy collected in non-heating periods to use in heating periods, which can not only alleviate the above contradictions, but also Improving the guaranteed rate of solar energy and the comprehensive utilization efficiency of solar energy throughout the year is one of the effective ways to realize the continuous and adjustable operation of the ...
