Description

New Ceiling Type Fresh Air Machine

technical field

The utility model belongs to the field of fresh air fans, and relates to a suspended ceiling type fresh air blower, in particular to a novel suspended ceiling type fresh air blower.

Background technique

The fresh air fan is an effective air purification equipment that can circulate the indoor air. On the one hand, the indoor dirty air is discharged outside, and on the other hand, the fresh outdoor air is sterilized, disinfected, filtered and other measures, and then input into the room. , so that the room is fresh and clean air all the time.

In winter, the outdoor air temperature is low, and when the cold air enters the fresh air fan, due to the large temperature difference with the indoor, it is easy to generate frost in the cabinet. In order to solve this problem, the existing method is to install a heater at the outlet of the fresh air in the casing. Although the problem of frosting of the casing is solved, the frosting of the heat exchange core cannot be avoided, because the cold air first needs to It can be discharged from the fresh air outlet after heat exchange with the indoor air through the heat exchange core. Therefore, frost is also easy to form in the heat exchange core.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art, and provide a new type of ceiling-type fresh air blower that can make the fresh air directly enter the room without heat exchange.

The technical solution adopted by the utility model to solve technical problems is:

A new type of ceiling-mounted fresh air fan, including a casing, a heat exchange core and a fan. The casing is a cuboid, and an indoor air inlet and a fresh air outlet are formed on the left side wall of the casing. The wall is equipped with an indoor air outlet and a fresh air inlet. A hexagonal cross heat exchange heat exchange core is installed in the casing. The hexagons of the heat exchange core are respectively connected to the side walls of the casing through partitions. The inlet, the indoor air outlet, the fresh air inlet and the air inlet outlet are all equipped with filter elements, and a blower fan is respectively installed at the indoor air outlet and the fresh air outlet, and an electric heater is installed outside the fresh air inlet casing.

Moreover, a triple filter element is installed at the indoor air outlet, which are primary filter element, medium effect filter element and high efficiency filter element.

Moreover, an electrostatic precipitator is installed inside the fresh air inlet filter element.

Advantage and positive effect of the present utility model are:

1. The fresh air fan is equipped with an electric heater on the outside of the fresh air inlet casing. The fresh air is preheated before entering the casing, which reduces the temperature difference between the fresh air entering the casing and the indoor air, and not only avoids the temperature difference of the casing. Frosting avoids the frosting of the heat exchange core.

2. This new fan is equipped with triple filter elements at the indoor air outlet, which are primary filter elements, medium effect filter elements and high efficiency filter elements. Compared with traditional fresh air fans, medium-efficiency filter elements and high-efficiency filter elements are added to improve the filtering effect of indoor air, so that the indoor air discharged outdoors will not pollute the atmosphere and protect the environment.

3. An electrostatic precipitator is installed on the inner side of the filter element of the fresh air inlet of the fresh fan. The electrostatic precipitator improves the dust removal efficiency and can remove a wide range of particle sizes, which makes up for the shortage of the filter element.

Description of drawings

Fig. 1 is the structural representation of the utility model.

detailed description

The utility model will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the utility model.

A new type of ceiling-mounted fresh air fan, including a casing 2, a heat exchange core 4 and a fan 10. The casing is a cuboid, and an indoor air inlet 1 and a fresh air outlet 11 are formed on the left side wall of the casing. The right side wall of casing is shaped on indoor air outlet 9 and fresh air inlet 8. A hexagonal cross heat exchange type heat exchange core is installed in the casing, and the hexagons of the heat exchange core are respectively connected to the side walls of the casing through partitions 3 . Filter element 6 is all installed in indoor air inlet, indoor air outlet, fresh air inlet and air inlet outlet, respectively installs a blower fan at indoor air outlet and fresh air outlet.

In order to avoid frosting of the casing and the heat exchange core, an electric heater 7 is installed outside the casing of the fresh air inlet.

Moreover, a triple filter element is installed at the indoor air outlet, which are primary filter element, medium effect filter element and high efficiency filter element.

In order to further improve the dust removal efficiency and make up for the defect of the filter element, an electrostatic precipitator 5 is installed inside the inlet filter element of the fresh air.

What is described above is only the preferred embodiment of the present utility model, and it should be pointed out that for those of ordinary skill in the art, without departing from the premise of the utility model concept, some deformations and improvements can also be made, and these all belong to the present invention. Protection scope of utility model.
