Description

Energy-saving wall-mounted fresh air machine

technical field

The utility model belongs to the field of fresh air fans, and relates to a wall-mounted fresh air fan, in particular to an energy-saving wall-mounted fresh air fan.

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.

Usually, there is a heat exchange core inside the fresh air fan. When the indoor exhaust air and the fresh air flow through the heat exchange core in a positive crossing manner, due to the temperature difference and steam partial pressure difference in the air flow on both sides of the air flow partition, the two air flows The phenomenon of heat and mass transfer occurs when passing through the partition plate, causing a total heat exchange process.

In the existing wall-mounted fresh air fan, the indoor air must exchange heat with the fresh air through the heat exchange core before entering the room. However, this setting is not economical and applicable in some cases, and instead causes waste of energy, it is superfluous. For example, on a hot summer night, the outdoor temperature is lower than the indoor temperature, and people need cool fresh air to enter the room. In this case, if heat exchange is performed, the temperature of the fresh air will be increased instead, which is not only counterproductive, but also a waste of energy. So how to make fresh air directly enter indoor under the suitable situation of temperature is the technical problem to be solved by the utility model.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art, and provide an energy-saving wall-mounted fresh air blower with a scientific and reasonable structural design, which can prevent indoor air from exchanging heat with fresh air.

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

An energy-saving wall-mounted fresh air fan, including a casing, a heat exchange core and a fan. The casing is a cuboid, and a heat exchange core is installed in the casing. The cross section of the heat exchange core is hexagonal , the angle closest to the left side wall of the casing is angle F, and the angle closest to the right side wall of the casing is angle C. On the right side wall of the casing, there are fresh air inlets and indoor air exhaust outlets, which are connected with the fresh air inlets. The fresh air exhaust grill is made on the left side wall of the cabinet and the left part of the front side wall diagonally, and the indoor air inlet grill is made on the left part of the rear side wall of the cabinet diagonally to the indoor air exhaust port , between the upper left corner of the casing and the F angle of the heat exchange core, the left side partition is obliquely connected, and a right side partition is transversely connected between the C corner of the heat exchange core and the right side wall of the casing. Install the fresh air exhaust fan and filter element on the left partition near the fresh air exhaust grid, install the indoor air exhaust fan at the indoor air exhaust outlet, and install the indoor air exhaust fan on the right side of the front wall of the cabinet near the indoor air exhaust outlet. Bypass fan.

Moreover, triple filter elements are installed at the exhaust outlet of the indoor air, which are primary filter elements, medium effect filter elements and high efficiency filter elements.

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

Advantage and positive effect of the present utility model are:

The fresh air fan installs a bypass fan near the indoor air exhaust outlet. After the bypass fan is turned on, the indoor air is directly discharged to the outside without passing through the heat exchange core. There will be heat exchange, and the fresh air will be discharged directly into the room without heat exchange. The wasteful use of the heat exchange core is avoided when the temperature is suitable, the utilization rate of the heat exchange core is improved, and the service life thereof is prolonged.

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.

An energy-saving wall-mounted fresh air fan, comprising a casing 3, a heat exchange core 4 and a fan 9, the casing is a cuboid, and a heat exchange core is installed in the casing, the cross section of the heat exchange core is Hexagonal, the angle closest to the left side wall of the casing is F angle, the closest angle to the right side wall of the casing is C angle, and the fresh air inlet 7 and the indoor air exhaust port are formed on the right side wall of the casing 8. A fresh air exhaust grid 11 is formed on the left side wall of the casing and the left part of the front side wall diagonally to the fresh air inlet, and a fresh air exhaust grid 11 is formed on the left side of the rear side wall of the casing diagonally to the indoor air exhaust port. Indoor air intake grid 1. Between the upper left corner of the casing and the F angle of the heat exchange core, the left partition 2 is obliquely connected, and a right partition 12 is transversely connected between the C corner of the heat exchange core and the right side wall of the casing. Fresh air exhaust fan 9 and filter element 6 are installed on the left side partition near the fresh air exhaust grid, and indoor air exhaust fan 9 is installed at the indoor air exhaust outlet. Multiple filter elements 6 are installed at the fresh air inlet.

The innovation point of the present utility model is:

A bypass fan 10 is installed on the right part of the front side wall of the casing near the indoor air exhaust port. After the bypass fan is turned on, the indoor air is directly exhausted to the outside through the indoor air exhaust port without passing through the heat exchange core, and the fresh air passes through the heat exchanger at the same time. Since the exchange core does not meet the indoor wind, there will be no heat exchange, and the fresh air will be directly discharged into the room without heat exchange.

The fan has three air ducts in total, the first one is the fresh air intake air duct; the second one is the exhaust channel where the indoor air passes through the heat exchange core; the third one is the exhaust air channel where the indoor air does not pass through the heat exchange core .

In order to prevent the indoor air from being exhausted to the outside and causing pollution to the environment, triple filter elements are installed at the exhaust outlet of the indoor air, which are primary filter elements, medium-efficiency filter elements and high-efficiency filter elements.

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

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.
