The invention provides a system and a method for solar energy centralized hot water supply for a high-rise residence. The system comprises a solar heat collection system, a heat accumulation system, a control system, a pipeline system and an auxiliary system, wherein the system is provided with a heat collection water tank and a constant-temperature heat supply water tank, a circulating pump is arranged between the heat collection water tank and the constant-temperature water tank, the starting and the stopping of the circulating pump are controlled by the temperature of the heat collection water tank and the water level of the constant-temperature water tank, a running water replenishing pipe is connected with the heat collection water tank, a solenoid valve is arranged on a connecting pipe, a water level sensor is arranged inside the heat collection water tank, the opening and the closing of the solenoid valve are controlled by water level signals of the water level sensor, a hot water supply water return end pipe is connected with the heat collection water tank, a water return pump is arranged on the water return end pipe, end low-temperature water is returned to the heat collection water tank, and the temperature is increased through a heat collector, so that the temperature of the constant-temperature water tank is guaranteed, expenses of complementary energy sources are reduced, the utilization ratio of solar energy is improved, full-automatic water replenishing is achieved, and water is supplied at the fixed temperature at the fixed time.
Description
technical field [0001] The invention relates to a solar centralized hot water supply system and method for high-rise residential buildings. Background technique [0002] At present, with the increasing shortage of conventional energy sources, solar water heating systems are promoted. In the promotion and application, the integration of solar energy and buildings has become the dominant one. The most widely used in the integration of buildings is the concentrated heat collection system, which is characterized by The solar collector heats the cold water and stores the heated hot water in the thermal insulation water tank. The system collects heat and supplies the same water tank, and the hot water is sent to the user's water point through the hot water supply pipe. The characteristics of this system are low cost, simple system, few control points, hot water temperature is not constant, the water tank is basically full of water, hot water is not fully utilized, and auxiliary en...
