Assembly type light steel passive house with near zero energy consumption

Abstract

The invention relates to an assembly type light steel passive house with near zero energy consumption, comprising a house body composed of an indoor floor, walls and a roof; and the walls comprise a plurality of inner walls and a plurality of outer walls and are used for isolating a plurality of indoor spaces. The passive house further comprises a fresh air total heat exchange system, a heat exchanger communicates with the outside of the house body through an air supply inlet pipeline, and the heat exchanger communicates with each indoor space through an air supply outlet pipeline. The heat exchanger also communicates with each indoor space through an air exhaust inlet pipeline, and communicates with the outside of the house body through an air exhaust outlet pipeline. During use, outdoorfresh gas is introduced into the air supply inlet pipeline, enters the air supply outlet pipeline through the heat exchanger, and then enters the corresponding indoor space through the air supply outlet pipeline, and meanwhile, foul gas in the indoor space is introduced into the heat exchanger through the air exhaust inlet pipeline and is exhausted through the air exhaust outlet pipeline, so thatfresh gas and the foul gas are subjected to heat exchange.

Description

technical field [0001] The invention relates to the technical field of energy-saving buildings, in particular to an assembled light-steel passive house with nearly zero energy consumption. Background technique [0002] Under the background of global warming and energy shortage, energy-saving buildings with high energy efficiency and low emission as the core are playing a vital role in realizing national energy security and sustainable development. Passive house is a combination of various passive energy-saving means such as natural ventilation, natural lighting, solar radiation heat gain and indoor heat gain from non-heating sources, and high-efficiency energy-saving technologies for building envelopes. On the premise of ensuring the comfort of the indoor environment, through Significantly reduce building heating / cooling loads and get rid of dependence on active mechanical heating and cooling systems to the greatest extent, thereby reducing building heating and cooling energ...

AI Technical Summary

Problems solved by technology

According to the latest passive house building standards, the indoor temperature must not exceed 26°C in summer and not lower than 20°C in winter, and the frequency of indoor air replacement should not be lower than 0.6 times per hour, but the existing light steel structure integration Most of the building exterior walls of the house have high thermal conductivity, poor thermal insulation effect, poor air tightness, large amount of indoor and outdoor exchange of hot and cold air, and cannot guarantee the temperature inside the house. It is hot in summer and cold in winter, which cannot meet the above requirements, and the comfort is poor.
