High-airtightness passive house and construction process thereof

Abstract

The invention discloses a high-airtightness passive house and a construction process thereof. The high-airtightness passive house comprises a wall body, wherein a roof is mounted at the top end of the wall body, a solar panel is mounted at the top end of the roof, a fresh air assembly is mounted at the top of the wall body, and an air exchange chamber is formed in the middle of the top of the wall body. According to the high-airtightness passive house, by arranging the air exchange chamber, an inner air cavity, an outer air cavity, an air conveying groove, an upper air hole, an arc-shaped baffle, a lower air hole, an air inlet pipe and an air inlet hole, the lower air hole is opened, and air enters the air conveying groove, the outer air cavity, a connecting air pipe and the inner air cavity from the lower air hole; and finally 2, by arranging the connecting air pipe, an exhaust pipe and an exhaust baffle, cold air in the air exchange chamber is preheated through waste heat of hot air passing through the inner air cavity and the outer air cavity, the preheated air enters a room through the air inlet hole, the temperature difference between outdoor air and indoor air is reduced, fresh air can enter the room during refrigerating and heating, thus the indoor air is fresher, and the environment is more comfortable.

Description

technical field [0001] The invention relates to the technical field of passive houses, in particular to a highly airtight passive house and its construction technology. Background technique [0002] The passive house is a master of various technical products. By making full use of renewable energy, the sum of all the primary energy consumed does not exceed 120 kW·h / (square meter. year). Such a low energy consumption standard is achieved through high Heat insulation and sound insulation, strong airtight building exterior walls and renewable energy can be realized. "Passive house" is a new energy-saving building concept advocated abroad, and it is also an important opportunity and platform for my country to promote building energy conservation; [0003] However, the currently constructed passive houses cannot allow the fresh air to enter the room well during cooling and heating, and do not make full use of the exhausted gases, resulting in rapid heat loss when the passive house...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a highly air-tight passive house and its construction technology, which can effectively solve the problem that the currently constructed passive house in the above-mentioned background technology cannot pass fresh air into the room during cooling and heating, and the exhausted gas Insufficient utilization leads to rapid heat loss during heating in passive houses, reduced air tightness, poor cooling effect during cooling, and low resource utilization efficiency
