A Photovoltaic Photothermal Integrated Device

Abstract

The invention discloses a photovoltaic and photo-thermal integrated device. The photovoltaic and photo-thermal integrated device comprises a photovoltaic module, a temperature control box, a preheated water storage tank and a solar water heater, wherein the photovoltaic module comprises a photovoltaic cell and a water channel; a water inlet of the water channel communicates with an external tap water pipe; a water outlet of the water channel communicates with the temperature control box; the temperature control box communicates with the preheated water storage tank through a siphon; the bottom of the preheated water storage tank is provided with a cold water inlet and a cold water outlet; the cold water outlet of the preheated water storage tank communicates with the solar water heater through a water outlet pipe; the cold water inlet of the preheated water storage tank communicates with the external tap water pipe; and the bottom of the solar water heater is provided with a hot water outlet pipe. Through the tap water cooling photovoltaic cell, the photovoltaic and photo-thermal integrated device improves the power generation efficiency of the photovoltaic cell on one hand, effectively recovers and utilizes the thermal energy of the photovoltaic cell on the other hand and stores heated cooling water; in the using process, the heated cooling water is introduced into the solar water heater; and waste heat is utilized, the heating time is shortened, and energy is saved.

Description

technical field [0001] The invention relates to a photovoltaic photothermal integrated device, which belongs to the technical field of new energy. Background technique [0002] Solar energy utilization technology is generally divided into two types: solar heat collection technology and solar power generation technology.
