Simple and energy-saving fresh air ventilator

Abstract

A simple and energy-saving fresh air ventilator comprises an enclosure, an old air exhaust system, a fresh air system and a heat exchanger, wherein the old air exhaust system and the fresh air systemare arranged in the enclosure; 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 fresh air draught fan and atleast one high-efficiency filter are arranged in the fresh air exhaust area; the old air suction area comprises an air exhaust inlet arranged on the side face of the enclosure; a valve buckle is arranged among the heat exchanger, the air exhaust inlet and the fresh air exhaust area, a valve plate and louvers are arranged in the valve buckle and the valve plate and the louvers are arranged on the same plane; and a valve linkage mechanism is connected between the valve plate and the louvers and connected with a power device, and the louvers can be opened or closed while the valve linkage mechanism drives the valve plate to rotate. On one hand, the dwelling comfort level can be improved, the energy saving effect is remarkable, and the operating mode is diversified; and on the other hand, theutilization rate of space is greatly improved, and the structure is simplified.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a simple energy-saving fresh fan. 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 fresh air in the fresh air suction ar...

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

In some new fans, the valve is set in a cavity. The cavity itself takes up space, and the vertical arrangement between the two valves takes up even more space. Therefore, the position arrangement between the components and the structural design of the valve It is very important to the space utilization rate, and on the basis of simple structure and rational use of space, it is even more difficult to realize multiple operating modes
