Heat exchange energy-saving system for house building

Abstract

The invention discloses a heat exchange energy-saving system for a house building. The heat exchange energy-saving system comprises a temperature difference induction mechanism and a heat exchange ventilation mechanism which are arranged in a wall body, the heat exchange mechanism comprises a heat exchanger, and an outer side ventilation opening is formed in the end, close to the outer side of the wall body, of the heat exchanger; an inner side ventilation opening is formed in one end close to the inner side of the wall body, and a flow control unit is arranged at the inner side ventilation opening and adjusts the flow passing through the inner side ventilation opening according to the temperature difference between the inner side and the outer side of the wall body. The ventilation efficiency inside and outside the house can be controlled according to the temperature difference inside and outside the house, when the temperature difference is large, the ventilation efficiency is reduced, the heat exchange time is prolonged, external air enters the house after sufficient heat exchange, heat preservation and energy conservation of the house are more emphasized when air circulation is guaranteed, and meanwhile the comfort of people is improved; when the temperature difference is small, the air exchange efficiency is improved, rapid air exchange is carried out, the house can be rapidly ventilated, and fresh indoor air is guaranteed.

Description

technical field [0001] The invention belongs to the field of house construction engineering, and specifically relates to a heat exchange energy-saving system for house construction. Background technique [0002] Houses are places where people live and shelter them from wind and rain. When the temperature difference between the outside environment and the house is large, people hope that the house has a good thermal insulation function so that people can live comfortably in the house; but because people Living in a house, people have the need to breathe fresh air, so people also hope that the house has good ventilation, which is contradictory to a certain extent. At present, people use the air-conditioning fresh air system to solve the problem of heat preservation and ventilation, but this will greatly increase the load of the air-conditioning fresh air system and increase energy consumption when the temperature difference between the inside and outside of Fengwu is large.
