Double-fan double-air-path pipeline-free system

Abstract

The invention discloses a double-fan double-air-path pipeline-free system which comprises a front-end main machine, a front panel is arranged between a rear cavity shell and a front cavity shell, a center partition plate is used for dividing the rear cavity shell into an air inlet path and an air outlet path, an air inlet fan module is arranged in the air inlet path, and an exhaust fan module is arranged on the air outlet path. An external air outlet and an external air inlet are formed in the bottom of the rear cavity shell, an internal air outlet, an internal air inlet and an air valve control module are arranged on the front panel, an internal air outlet valve is arranged on the internal air outlet, an internal air inlet valve is arranged on the internal air inlet, and the air inlet fan module communicates with the internal air inlet valve. The exhaust fan module communicates with the internal air outlet valve, indoor air inlets and air outlets are formed in the two sides of the front cavity shell, a heat exchange chamber is arranged on the inner side of the front cavity shell and connected with the internal air outlet valve and the internal air inlet valve, and a heat exchange body is arranged in the heat exchange chamber. According to the double-fan double-air-path pipeline-free system, the purposes of intelligence, easy use and energy saving are achieved, and it is ensured that the indoor environment air quality is good.

Description

technical field [0001] The invention relates to the field of fresh air ventilation, and more specifically relates to a ductless system with two blowers and two air passages. Background technique [0002] Most of the current fresh air systems are pipe installation systems, which are divided into one-way flow, two-way flow, and two-way flow systems with heat exchange according to the ventilation method; when installing, it is necessary to lay pipes indoors, and when laying on the top, the room needs to be of sufficient height. If it is laid with ground air supply flat pipes, it will also reduce the height of the room, and it must be completed before the decoration construction. Moreover, due to the small cross-sectional area of ​​the flat tube for air supply, the air supply effect cannot achieve good air quality. Many European markets use special fans with high static pressure. When the traditional full heat exchange of fresh air works in the northern region, although heat a...
