A dual temperature adaptive building cooling energy saving device based on passive radiation cooling

Abstract

The application discloses a double-temperature self-adaptive building cooling and energy-saving device based on passive radiation cooling, which is composed of a straight pipe coated with an adaptive passive radiation refrigeration coating outside a room, a top coil pipe for heat exchange inside the room, a top liquid storage tank, a bottom liquid storage tank, an electromagnetic valve and a temperature sensor connected with a central controller and a pipeline system connected with the central controller. The device can effectively cool the indoor building through passive radiation refrigeration technology, and the working fluid is introduced into the top of the indoor room for direct heat exchange, so that the heat exchange efficiency is higher. Meanwhile, the working state can be automatically adjusted according to the self-regulating effect of the adaptive passive radiation refrigeration coating and the difference between the indoor and outdoor temperatures and the set temperature, so that the overcooling of the building is avoided, the energy of the building is saved throughout the year, and the advantages of energy saving and environmental protection, simple operation and structure and wide application range are achieved. The cooling and energy-saving device is particularly suitable for buildings or devices with high internal heat, such as machine rooms, boiler rooms, steelmaking workshops and power transformation boxes.
