Fresh air device for house and production method of fresh air device

Abstract

The invention discloses a fresh air device for a house and a production method of the fresh air device, belongs to the technical field of construction engineering, and particularly relates to a ventilation technology and equipment of the house. The fresh air device comprises an outer exhaust outlet, an outer air inlet, an inner exhaust outlet, an inner air inlet, an outer air duct wall, an inner air duct wall, spiral air inlet duct fins, an air-conditioning regulator, an outer wall of a house exterior wall, an inner wall of the house exterior wall and an indoor floor. The air specific weight difference is used as power or mechanical and electrical auxiliary power; the spiral air inlet duct is adopted for increasing the heat exchange area and efficiently recovering waste heat, so that a good energy-saving effect is realized, and further fresh air with optimum temperature is provided for the indoor of the house; in addition, the fresh air device has the advantages of simplicity in manufacturing, convenience in mounting and low construction and maintenance cost; and the device is arranged in the exterior wall of the house in a concealed way, so that the space is saved, and excessively adverse influence on viewing of an outer facade and an inner facade is avoided. The fresh air device is particularly suitable for exchanging fresh air of the house under the conditions of cold climate in the north and other great indoor and outdoor temperature difference.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to house ventilation technology and equipment, in particular to a house fresh air device and a manufacturing method thereof. Background technique [0002] 1. A low-energy indoor fresh air replacement device (201420224678.3), in which more than one fan is installed in the outdoor unit, and the fresh air flows into a stainless steel corrugated pipe exchanger containing fins through an arc-shaped channel diversion interface. The other end of the corrugated pipe exchanger is connected to the indoor unit, which is characterized in that: the outdoor unit is equipped with a dirty air fan and a fresh air fan, and there is a shunt box inside the outdoor unit, which is connected to the shunt interface of the corrugated pipe exchanger, and the air inlet and outlet are isolated , the inner and outer tubes of the corrugated pipe exchanger are both corrugated tubes, a...
