A fresh air system for building refrigeration and heating

Abstract

The invention discloses a fresh air system for cooling and heating of a building. The inner wall of the building wall is provided with a ventilation groove, the ventilation groove is connected with an air passage penetrating through the building wall, and the building wall is provided with a thermal insulation partition covering the ventilation groove. The thermal insulation plate is provided with a plurality of ventilation holes in an array, and the outside of the building wall is provided with transparent glass covering the air passage. The transparent glass is connected with a fresh air pipe, and the fresh air pipe is connected with the solar heat exchange component and the refrigeration unit. The components are connected, and the heating and cooling in the building are respectively realized through the solar heat exchange component and the refrigeration component. The present invention can convert solar energy into heat or cold air of the fresh air system, so as to realize the cooling and heating needs in the building. , the solar energy can also be stored in the phase-change heat accumulator for use when the solar intensity is not enough. By setting solar power generation, the energy required for cooling can be realized. The invention also sets an air filter, which can ensure the fresh air system air the quality of.

Description

technical field [0001] The invention belongs to the bidirectional technical field, and in particular relates to a fresh air system for cooling and heating of a building. Background technique [0002] The fresh air system is based on the principle that fresh air is sent to the room with special equipment in a closed room, and a "fresh air flow field" will be formed indoors to meet the needs of indoor fresh air ventilation. The current fresh air system generally only can achieve the needs of ventilation. However, with the rapid development of my country's economy, the contradiction between energy and development has become a common concern of all sectors of society. As the world's largest construction market, my country's energy consumption per unit building area is more than 2 to 3 times that of developed countries. According to the research and practice of the energy industry in the past 30 years, it is generally believed that building energy conservation is the most potenti...
