Embodiment Construction

[0026] The semiconductor refrigeration assembly adopted in the present invention is realized by utilizing the Peltier effect. The movement of charge carriers in the conductor forms an electric current. Since the charge carrier is at different energy levels in different materials, when it moves from a high energy level to a low energy level, it releases excess energy; on the contrary, when it moves from a low energy level to a high energy level, it absorbs energy from the outside. Energy is absorbed or released in the form of heat at the interface of two materials. When current flows through the interface of two different conductors, due to the different directions of direct current flow, heat absorption and heat release will occur at the intersection of the interface, which is called the Peltier effect. At present, there are relatively mature products of semiconductor refrigeration components made of Peltier effect.

Abstract

The invention discloses a composite solar photovoltaic hot-water cold supply and heating system for a building, which mainly comprises a solar photovoltaic hot water sunshade plate, a semiconductor refrigerating assembly, a separate heat pipe with a short pipe bundle, an integral gravity heat pipe, a heat exchange header and the like. The system is characterized in that the solar photovoltaic hotwater sunshade plate and the semiconductor refrigerating assembly form a loop to realize indoor refrigeration and heat supply in summer and in winter by using solar power generation respectively; andthe separate heat pipe, the integral gravity heat pipe, the heat exchange header, a coil pipe, a water tank and the like form a hot water system to generate hot water when cooling and heating of the semiconductor refrigerating assembly are realized in summer and in winter respectively. The system solves the problem that heating and hot water generation cannot be realized at the same time in the combined application of the traditional solar photovoltaic power generation and semiconductor refrigerating assemblies; and the introduction of the separate heat pipe and the gravity heat pipe improvesthe refrigerating and heating efficiency and enlarges the application range.

Description

technical field [0001] The invention relates to a building composite solar photovoltaic hot water cooling and heating system, which belongs to the field of solar energy utilization and air conditioning and ventilation. Background technique [0002] Solar energy is a clean, efficient and inexhaustible new energy source, so the governments of all countries regard the utilization of solar energy resources as an important content of the national sustainable development strategy. my country's solar thermal heating technology has been applied to a certain extent, but there has been no good development in solar cooling. At present, the main technologies of solar energy in building air-conditioning and refrigeration include solar absorption refrigeration, solar adsorption refrigeration, solar jet refrigeration, solar solution dehumidification refrigeration, solar power generation driven compressor refrigeration, and solar semiconductor refrigeration. These methods are all inefficien...
