Comfortable energy-saving fresh air ventilator and regulating method thereof

Abstract

The invention provides a comfortable energy-saving fresh air ventilator and a regulating method thereof. The comfortable energy-saving fresh air ventilator comprises a casing, an old air exhaust system, a fresh air system and a heat exchanger, wherein the old air exhaust system and the fresh air system are arranged in the casing; the heat exchanger is arranged between the old air exhaust system and the fresh air system; the old air exhaust system comprises an old air suction area and an old air exhaust area which are arranged independently; the fresh air system comprises a fresh air suction area and a fresh air exhaust area which are arranged independently; and a valve linkage mechanism is arranged among the heat exchanger, the old air suction area and the fresh air exhaust area. The valvelinkage mechanism is selectively controlled according to the outdoor temperature, so that indoor air is only circulated indoors or is dually circulated indoors and outdoors. The invention further comprises a regulating method of the comfortable energy-saving fresh air ventilator. The comfortable energy-saving fresh air ventilator and the regulating method have the advantages that on one hand, thehabitant comfortability can be greatly improved, the energy-saving effect is remarkable, the operation modes are diversified, and the function is multiple; and on the other hand, the structure is greatly simplified, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a comfortable and energy-saving fresh fan and its adjustment method. Background technique [0002] Existing indoors generally purify the air in the room by installing a fresh air blower. When the fresh air blower works, the outdoor fresh air can be sucked into the room, and the old indoor air can be discharged to the outside. Due to the different temperatures in spring, summer, autumn and winter, especially the large temperature difference between summer and winter, it is an urgent technical problem to meet the indoor temperature suitability. [0003] In order to solve the above problems, the existing fresh air fans usually set up a bypass area. In summer and winter, the bypass valve in the bypass area is disconnected, and the fresh air must pass through the heat exchanger for cooling or heating; In spring and autumn, the bypass valve is automatically opened, and the fr...

AI Technical Summary

Problems solved by technology

But in winter and summer, even if the outdoor air enters the room through the heat exchanger, it will have a great impact on the indoor temperature, which cannot improve the living comfort.

[0004] Among the existing fresh air fans, there are still multiple independent valves set in different areas to control the flow or blockage of different channels respectively, but this does not solve the problem that the indoor temperature is greatly affected in winter and summer, and multiple independent valves The valves need to be set separately, not only the structure is complicated, but also multiple areas for placing the valves may be set, which takes up a lot of space

[0005] Moreover, the valve linkage mechanism of the existing fresh air blower is located in the chamber, which occupies a large area, and due to unreasonable layout, such as two vertical valves, the overall volume of the fresh air blower is very large, and some are even divided into two parts. A body, resulting in a larger footprint and less compact structure
