A Small Multi-generation System Based on Sky Radiation Suitable for Outdoors

Abstract

The present invention provides a small-scale multi-generation system based on sky radiation suitable for outdoors, comprising: a part of the sky radiation cold water circuit transmits cold energy to the sky radiation cold water production module through the first heat exchanger, and the other part of the cold water absorbs semiconductor thermoelectricity The heat of the effect module is discharged to the hot water storage tank through the second heat exchanger, and the last part is directly sent to the cold water supply end; the radiant refrigeration circuit cools down through the second heat exchanger and the semiconductor thermoelectric effect module for a second time, and sends the cold energy to Radiation end; solar power generation and heat collection integrated circuit supplies electric energy through the power storage device on the one hand, and sends heat to the hot water storage tank through the heat collector on the other hand, and the hot water storage tank can provide hot water. The present invention has high comprehensive energy efficiency, energy saving, practicality and multi-level utilization of energy, and can simultaneously realize cold water supply, hot water supply, power supply, and radiant cooling, and solve the energy multi-supply demand of small outdoor places.

Description

Technical field [0001] The present invention relates to the field of energy application technology, specifically to a small multi-generation system based on sky radiation suitable for outdoors. Background [0002] With the continuous development of society, outdoor sports, leisure, tourism, operations and other groups are also increasing, and the demand for outdoor energy supply by such groups is also increasing, such as iced drinks, multi-functional tents, bait refrigeration, high-end agriculture, etc. On the other hand, the traditional multi-generation energy system is often suitable for indoor environments, the system equipment is large and not easy to move, and for outdoor places that lack power supply and energy applications have mobility and temporaryness, they cannot be better applied. Therefore, how to efficiently use the characteristics of outdoor environment solar energy resources, open air and other characteristics to achieve multi-level utilization and multi-faceted ...

Problems solved by technology

For a single photovoltaic power generation system, since the temperature of the solar panel increases by 1°C, the photovoltaic power generation efficiency decreases by about 0.4% to 0.5%, and more than 80% of the energy of sunlight reaching the solar panel is converted into heat energy, making the operating temperature of the solar panel Usually above 50°C, which seriously affects the efficiency of photovoltaic power generation

[0006] The invention patent with the publication number CN111207530A discloses a composite refrigeration device coupled with a semiconductor refrigerator and a sky radiation cooling body. The patent combines active semiconductor refrigeration technology and passive sky radiation refrigeration technology to cool the coolant, and then provides cooling amount, but this invention only contains a refrigeration unit, which cannot meet the needs of outdoor multi-energy use, and the heat of the hot end of the semiconductor is not utilized, and the energy utilization has not been maximized
