Abstract

The invention discloses a solar photovoltaic-thermal combined intelligent water supply system in low rise buildings. Solar energy is converted into electric energy and thermal energy through a photovoltaic-thermal integrated device, the electric energy is used for electric heating of user insulation water tanks, and when the electric energy is surplus, the electric energy is stored in energy storage battery devices. The thermal energy is from cooling water of the photovoltaic-thermal integrated device, the water temperature is low, the low-temperature water is delivered to a trough-type concentrating solar thermal utilization device to be reheated, the temperature of hot water is increased, the hot water is stored in a concentrated insulation water tank, and hot water resources are distributed reasonably. Electric heating units are mounted in the user insulation water tanks and used for electric heating in cloudy and rainy weather. Even on the weather conditions of cloudy days, winter and the like, the system can provide hot water meeting user demand continuously.

Description

technical field [0001] The invention relates to a solar photovoltaic photothermal combined intelligent water supply system in a low-rise building, belonging to the technical field of energy utilization. Background technique [0002] With the rapid development of China's economy, people's living standards continue to improve, and the demand for energy continues to increase. At present, the main ways of providing hot water to residents include solar water heaters and electric heating water heaters. Solar water heaters can provide reliable domestic hot water under good weather conditions, but in continuous rainy weather, solar water heaters cannot provide domestic hot water. The electric heating water heater converts electric energy into heat energy, and the process of energy conversion is that high-grade electric energy is converted into low-grade heat energy, and a large amount of energy waste is generated in the energy conversion. [0003] The conversion efficiency of sola...
