Winter and summer temperature adjusting device based on radiation cooling and solar energy utilization and construction method of winter and summer temperature adjusting device

Abstract

The invention discloses a winter and summer temperature adjusting device based on radiation cooling and solar energy utilization and a construction method of the winter and summer temperature adjusting device. The winter and summer temperature adjusting device is constituted by a radiation cooling structure and a heat absorbing layer; the radiation cooling structure is composed of a reflecting layer, an emission layer and a wind screen, the emission layer is arranged between the reflecting layer and the wind screen, the wind screen is composed of an air layer and a covering material layer, andthe air layer is located between the emission layer and the covering material layer; the reflecting layer reflects sunlight out, and the emission layer emits heat in a temperature-adjusted medium outin an infrared ray mode; and the heat absorbing layer is composed of a solar heat-absorbing material layer and a metal plate, and the metal plate is located between the solar heat-absorbing materiallayer and the reflecting layer of the radiation cooling structure and is closely combined with the radiation cooling structure. The winter and summer temperature adjusting device can provide passive temperature decreasing and increasing for certain occasions and equipment, and achieves the energy saving effect.

Description

technical field [0001] The invention relates to the field of building cooling, and more specifically relates to a winter and summer temperature regulating device and construction method based on radiation cooling and solar energy utilization. Background technique [0002] At present, many fields need to cool down and heat up, such as construction, military industry, electronics, mechanical equipment, etc. When the outdoor temperature of the building is high, air conditioners are needed to cool down; in the absence of air conditioners, electric fans or water evaporation are used to cool down. When the outdoor temperature is low, heating is required to raise the temperature, consuming primary energy or secondary energy. In the field of mechanical equipment, heat will be emitted after the equipment is in operation. If the temperature is high to a certain extent, it will affect the operating efficiency of the equipment and must be cooled down. If it is placed in a cold area, th...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the cooling energy consumption is large or the active cooling cannot be used, the heating energy consumption is large or the active heating cannot be used, and the simple use of radiation cooling may cause an increase in the heat load in winter. The temperature-regulating device and construction method used in winter and summer. The device is placed on the upper part of the temperature-regulated medium. It is used to emit the heat of the temperature-regulated medium in summer, and to absorb solar radiation heat to the temperature-regulated medium in winter. It can be used for some Occasions and equipment provide passive cooling and heating to play a role in energy saving
