Abstract

The invention discloses a thermal energy comprehensive utilization device for supplying comfortable hot water and generating power through solar energy. The device mainly comprises two parts, namely a solar hot water system and a Rankine cycle system. The device can be adjusted according to a water supply temperature set by a user, water is heated by a solar thermal collector, and effluent of thethermal collector is subjected to thermal energy recovery or cyclic heating. If the temperature of the effluent of the thermal collector is higher than the set water supply temperature, the Rankine cycle system is started to convert high-temperature thermal energy into electric energy; and if a water supply temperature of a water tank on a user side is lower than the set temperature, the water tank of the user is heated through the solar thermal collector, so that the condition that the water tank of the user provides comfortable hot water all the time is ensured. By the device, utilization amount and utilization efficiency of solar energy can be improved, the comfort level of domestic hot water is improved, the solar energy can be comprehensively used for supplying the domestic hot waterand generating the power, and evaporation waste of a water source caused by excessive heat energy is prevented; and the device is suitable for technical upgrade and technical transformation of civil and industrial solar thermal collectors.

Description

technical field [0001] The invention relates to the field of renewable energy—solar thermal energy utilization and energy utilization rate, in particular to a thermal energy comprehensive utilization device that utilizes solar energy to realize hot water supply and power generation. Background technique [0002] Renewable energy is energy resources that can be used sustainably, such as water energy, wind energy, solar energy, biomass energy and ocean energy, etc., and there is no problem of resource depletion. As more and more countries adopt policies and measures to encourage renewable energy, the production scale and application scope of renewable energy are expanding. As far as solar energy is concerned, there are two ways to use solar energy: heat utilization and photoelectric conversion. Nowadays, solar water heaters are more used in solar heat utilization, which absorb solar radiation to heat water, supply hot water needed in people's life and production, and save ele...
