Background technique

Air quality is related to the quality of life of people. More and more people pay attention to the quality of air. However, the current large environment cannot fundamentally solve the problem of air purification. Therefore, more and more businesses and consumers choose indoor air purification equipment. There are various air purifiers on the market, but the air purifiers are limited by the volume of air they can purify, so they are not suitable for large-area houses and multi-room houses.

Utility model content

The purpose of this utility model is to provide an indoor air conditioning system suitable for large-area houses, especially houses with multiple rooms, especially a system that can adjust air quality and indoor temperature under different temperature conditions and different weather conditions. A simple, proven system solution.

The technical solution adopted by the utility model is a full-displacement purification fresh air system, which is installed in a residence containing at least one room, including floor-standing fresh air fans, fresh air delivery pipes, indoor air recovery pipes, and outdoor air intake channels; wherein, the The floor-standing fresh air fan includes a fan, a filter combination, a first air inlet, a second air inlet and at least one air distribution outlet; the first air inlet is connected to the outdoor air inlet channel, the second air inlet is connected to the indoor air recovery pipe, and the filter The net combination is arranged above the fan and below the air inlet; the air exhaust port of the fan is connected to the air distribution port, and the air distribution port is connected to the fresh air conveying pipeline; it also includes a control device, which includes a mode setting module, an external circulation module and internal circulation module; start the external circulation module and/or internal circulation module through the mode setting module; the first air inlet and the second air inlet are respectively provided with a first electric air valve and a second electric air valve connected to the control device Electric damper.

By adopting the above scheme, the alternation or switching of internal and external circulation can be realized, which can not only complete the exchange and purification of indoor and outdoor air, but also solve the problem that external circulation is not suitable when the outdoor air is extremely poor.

This system further proposes a purification system that can realize the indoor and outdoor temperature difference is too large, or under low temperature conditions: wherein the control device includes an indoor temperature acquisition module, an outdoor temperature acquisition module and a temperature comparison module; the first electric air valve An air inlet temperature sensor is arranged below the second electric air valve, and the air inlet temperature sensor is connected with the outdoor temperature acquisition module of the above-mentioned control device; an indoor temperature sensor is arranged indoors, and the indoor temperature sensor is connected with the indoor temperature acquisition module of the above-mentioned control device.
