Abstract

The invention relates to the technical field of building ventilation, in particular to a fresh air ventilation system with the function of switching ventilation modes; it includes a fresh air fan installed outdoors, an original air intake pipe connecting the air inlet of a room with the air supply port of the fresh air fan, and The air outlet of the connected room is connected with the original air outlet pipe of the air inlet of the new fan, the original air intake pipe is connected with a bypass air inlet pipe, and the original air outlet pipe is connected with a bypass air outlet pipe; the bypass air inlet pipe is connected with The junction of the original air inlet pipe is provided with an inlet pipe bypass valve, and the junction of the bypass air outlet pipe and the original outlet pipe is provided with an outlet pipe bypass valve; the inlet pipe bypass valve and the outlet The bypass valves of the trachea are all provided with control switches; the bypass valves are used to solve the technical problems in the prior art of energy waste caused by completely ventilating with fresh fans and the use of doors and windows with poor ventilation and no filtering function.

Description

technical field [0001] The invention relates to the technical field of building ventilation, in particular to a fresh air ventilation and ventilation system with the function of changing ventilation modes. Background technique [0002] At present, the commonly used fresh air system has only one ventilation mode. The fresh air ventilator discharges the indoor air and sends the outdoor air into the room. Due to the nationwide decline in air quality, most of the fresh air ventilators currently have air filtration functions, and a few have heat exchange functions. When the air quality is poor, it is necessary to use a fresh air ventilator for indoor and outdoor ventilation. However, when the outdoor air quality is good or under normal circumstances, the use of fresh air ventilators for ventilation results in a waste of energy, and the use of doors and windows for ventilation usually cannot achieve a good ventilation effect. [0003] Therefore, in view of the above problems, th...
