Title:
ONE-WAY FLOW MICRO-POSITIVE PRESSURE TEMPERATURE-ADJUSTING FRESH AIR INDOOR UNIT, AND SYSTEM AND OPERATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/051803
Kind Code:
A1
Abstract:
The present invention relates to the technical field of indoor fresh air temperature adjustment, and provides a one-way flow micro-positive pressure temperature-adjusting fresh air indoor unit, and a system and an operation method therefor. The fresh air indoor unit comprises a casing, a PM2.5 filter, a humidifier, a carbon dioxide concentration sensor, a heat exchanger, and a controller. An outdoor air inlet communicated with an inlet of the PM2.5 filter is provided on the back of the casing, and an outlet of the PM2.5 filter is communicated with an inlet of the heat exchanger; an outlet of the heat exchanger is connected to a silent fan mounted on top of the casing, and an air outlet of the silent fan is arranged upward or downward or horizontally. In the present invention, the fresh air temperature is adjusted to a set temperature by the heat exchanger, the fresh air is then pressed into an indoor space by the low-noise fan, and a one-way flow micro-positive pressure is maintained indoors by adjusting the air volume of the low-noise fan; when the indoor carbon dioxide concentration is higher than a health standard, the air supply amount is adjusted, so that the indoor space has a fresh air supply rate for ensuring human health, and the purposes of health, comfort, environment friendliness and energy saving are achieved.
