Problems solved by technology

[0005] The technical problem to be solved by the present invention is to solve the problem of high energy consumption for heating in passive buildings, and rely on technologies such as tunnel ventilation, fresh air heat recovery, and direct evaporative cooling without using mechanical heating or cooling. The requirement of indoor temperature of 25°C for buildings in winter and summer can achieve indoor thermal comfort and save a lot of building heating or cooling energy consumption; the shallow geothermal application technology of passive buildings is based on passive buildings, using shallow tunnels to The outdoor fresh air is introduced into the tunnel, absorbs the geothermal heat in the shallow soil to heat the fresh air, and sends the preheated fresh air into the building

Embodiment Construction

[0021] The principles and features of the present invention are described below, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0022] Provide a shallow geothermal application technology for passive buildings. This technology includes two application directions: preheating and cooling. The preheating process mainly occurs in winter, and the cooling process mainly occurs in summer:

[0023] The main flow of the indoor input air preheating process in winter is as follows: the first step, the outdoor cold air is collected into the air intake duct in the passive building, preheated in the first stage, and passed through two stages of coarse-efficiency filtration and medium-efficiency filtration. In the process of filtration, the cold air is filtered; the coarse-effect filter is to filter the large particles in the air, and the fiber material is used to minimize the resistance to the air duri...

Abstract

The invention discloses a shallow geothermal application technology of a passive building. The shallow geothermal application technology mainly includes preheating application and cooling application. A preheating process and a cooling process mainly include three steps: firstly, collecting outer air into an air inlet channel in the passive building, and filtering the collected air in the air inlet channel; secondly, transmitting the treated air into the passive building, and deeply burying the transmitted air into an underground ventilation pipeline, and preheating or cooling the air by the aid of formation depth and air temperature difference; thirdly, transmitting the treated air into an air supply pipeline distributed in the passive building, arranging a hot water heating coil or a direct evaporative cooler to treat the air again. According to the shallow geothermal application technology, structure is simple, the air in rooms is exchanged, the temperature of fresh air is adjusted, energy consumption is reduced, and the application technology has the advantages of low cost and energy consumption, wide application and the like in the use process.

Description

technical field [0001] The invention relates to the technical field of buildings, in particular to the shallow geothermal application technology of passive buildings. Background technique [0002] Xinjiang is a severely cold region, with a heating period of up to 6 months in winter (October 10 to April 10), while a cooling period of only 2 months in summer. As far as conventional buildings in severe cold areas are concerned, their heating energy consumption in winter (including fresh air energy consumption) is seven times that of summer cooling energy consumption, and fresh air energy consumption in winter accounts for 60% of the total heating energy consumption. [0003] Passive buildings, also known as passive low-energy buildings or passive houses, are currently the only state-of-the-art building energy-saving model that has been widely recognized by the government and the people. The heat transfer coefficient of the system, while adopting zero thermal bridge and high-pe...
