Novel heating and ventilation system for solar heat-collection and heat-accumulation wall

Abstract

The invention discloses a solar heat-collection and heat-accumulation wall in the technical field of solar utilization for buildings. A fan is additionally arranged at a lower air port of the traditional collection and heat-accumulation wall and enables the heated air to be conveyed into an indoor personnel working area. A corrugated plate plated with a selective absorption material on the surfaceis used as a heat-collection plate, and a phase-change heat-accumulation unit is added between the heat-collection plate and a building wall body, so that the heat-collection and heat-accumulation efficiency is increased. A transparent honeycomb structure is used for replacing a traditional honeycomb structure glass plate, so that the heat-insulation effect is improved. An air port with an air door and a fan are arranged on the upper part and the lower part of the wall body. Different running strategies can be adopted in the four seasons of the year, heat supply for the interior of a room inwinter and alleviation for excessive heat in the room in summer can be realized, and natural ventilation can be realized in the case of the need of ventilation, so that the comfort degree in the roomis increased. Flexible conversion between the functions of heat collection and heat accumulation can further be realized. The solar heat-collection and heat-accumulation wall has the characteristics of being reasonable in structure, energy-saving and environment-friendly, and wide in application field, and has a wide application prospect and a high popularization value in solar buildings.

Description

technical field [0001] The invention belongs to the technical field of solar energy utilization in buildings, and in particular relates to a solar heat collection and heat storage wall structure and operation control of a heating and ventilation system thereof. Background technique [0002] With the rapid development of society, the problem of energy utilization in our country is becoming more and more obvious. Compared with developed countries, our country is relatively backward in energy utilization and its efficiency is low. The energy waste caused by construction in our country is relatively serious every year. With the continuous increase of our population and the continuous improvement of people's living standards, the annual energy consumption of the construction industry is gradually increasing, causing a very large waste of energy. To solve these problems, adjusting the energy structure is an effective method, and using a large amount of clean energy is an effective...

Problems solved by technology

[0003] However, there are limitations in the utilization of solar energy, such as the use of solar energy is affected by weather and time, it cannot be used continuously for a long time without interruption, and the intensity of solar radiation varies across my country, so in terms of solar energy utilization, research The focus is on optimizing the collection and storage of solar energy

The solar thermal storage wall is an effective way to utilize solar energy in buildings, but the traditional solar thermal storage wall will cause the indoor temperature to fluctuate greatly with the outdoor temperature or the phenomenon of overheating in summer, and less consideration should be given to the heat of the indoor environment. comfort problem
