Small-sized energy-saving ventilator

Abstract

The invention provides a small-sized energy-saving ventilator which comprises a shell body composed of a top plate, a bottom plate, two long-edge side plates and two short-edge side plates. An intermediate partition plate for being connected with the top plate, the bottom plate and the two long-edge side plates is arranged inside the shell body, the intermediate partition plate is used for dividing the interior of a machine shell into two areas, one area is a heat exchanging area, and the other area is an exhausting area. A heat exchanger which is vertically placed is arranged in the heat exchanging area, two horizontally-rotating volute blowers are arranged in the exhausting area, and the two volute blowers are vertically stacked and are driven by the same double-shaft motor to rotate. In the small-sized energy-saving ventilator, the total stacked height of the two volute blowers is smaller than that of the heat exchanger, therefore, the whole height of the small-sized energy-saving ventilator depends on the height of the heat exchanger, therefore, under the premise that the ventilation requirement is ensured, the size of the small-sized energy-saving ventilator is reduced, and the small-sized energy-saving ventilator is suitable for being used in the house with the small installation space.

Description

technical field [0001] The invention relates to a small ventilation device, which belongs to the technical field of heat exchange. Background technique [0002] Along with the popularization and popularization of miniaturized houses, the demand for the use of small ventilation devices is increasingly strong. [0003] In the prior art, there are various designs of miniaturized ventilation devices. Among them, the thinnest ventilation device should be the ventilation device disclosed in the Chinese invention patent with the patent number ZL200510131429.5. The ventilation equipment includes: a fan device, a heat exchange unit and a casing, the casing has a first cavity and a second cavity, the heat exchange unit is placed in the first cavity, the fan device is placed in the second cavity, and the second cavity The cavity communicates with the first cavity. The casing of the ventilator has a thin and wide flat rectangular box shape, and the thickness of the casing is substant...

AI Technical Summary

Problems solved by technology

In the above design, the ventilation equipment is designed to be very thin, and the space between the air inlet of the fan and the box wall is very small, which will cause a very large resistance, resulting in a significant reduction in the air volume of the fan. Therefore, the actual air volume in use will be far less than 100CMH. In other words, in actual use, the above-mentioned thin models simply cannot meet the requirements of 33m 2 The ventilation requirements of the left and right single rooms

Because the actual residential area in China is much larger than 33m2 2 Therefore, the air volume generated by the ventilation system using the above-mentioned fans will be far from meeting the requirements of domestic houses. Therefore, the market versatility and transformability of the above-mentioned models have not been good.
