Problems solved by technology

The disadvantages of this method of ventilation are: 1. In the hot summer, when the air conditioner is used indoors, due to the large temperature difference between indoor and outdoor, if an ordinary exhaust fan is directly used to ventilate the room, it will affect the cooling effect of the air conditioner , increase energy consumption; 2. In the cold winter, due to the large temperature difference between indoor and outdoor, it also causes an increase in energy consumption

Embodiment Construction

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] The invention provides a fresh air ventilation system.

[0030] like figure 1 and figure 2 Shown: the fresh air ventilation system of the embodiment of the present invention mainly includes: the peripheral ventilation pipe 2 and the middle ventilation pipe 3, the middle ventilation pipe 3 is arranged in the peripheral ventilation pipe 2, and one end of the two ventilation pipes is provided with a Fan 1 for air supply and exhaust. The inner air suction port of fan 1 can suck indoor exhaust air, and the outer air suction port can send fresh air. The two-way ventilating device that peripheral vent pipe 2 and middle vent pipe 3 are formed, carries out ventilating to each floor. Optionally, the peripheral ventilation pipe 2 and the middle ventilation pipe 3 are equipped with an aperture type air volume regulating valve 9, which can realize...

Abstract

The invention relates to a fresh air ventilation system. The fresh air ventilation system comprises a peripheral ventilation pipe, an intermediate ventilation pipe and fans, wherein the intermediate ventilation pipe is arranged in the peripheral ventilation pipe; and the fans are arranged at one end of the peripheral ventilation pipe and one end of the intermediate ventilation pipe, and are used for blasting air and exhausting the air. By the optimized design and the structure provided by the invention, indoor and outdoor two-way ventilation can be realized; heat exchange can be performed on the blast air and the exhaust air through the wall of the intermediate ventilation pipe; heat recovery can be realized; and energy consumption can be reduced.

Description

technical field [0001] The invention relates to a fresh air ventilation system. Background technique [0002] With the improvement of people's living standards, the requirements for fresh air volume are also constantly increasing, and the increase in fresh air volume leads to an increase in energy consumption of air conditioners. At the same time, most air-conditioning systems do not use any exhaust energy recovery method, resulting in a large amount of low-grade energy wasted. [0003] At present, for ordinary families and offices, indoor pollution is becoming more and more serious, and now people mainly use common exhaust fans to ventilate the room. The disadvantages of this method of ventilation are: 1. In the hot summer, when the air conditioner is used indoors, due to the large temperature difference between indoor and outdoor, if an ordinary exhaust fan is directly used to ventilate the room, it will affect the cooling effect of the air conditioner , increase energy ...
