Abstract

The utility model provides a central air conditioning total heat exchange fresh air device, belongs to civilian central air conditioning new trend equipment field, including casing, filter, and the business turn over wind gap, the casing install in house furred ceiling top, be located between indoor suspended ceiling and the roof, the filter install in the casing, the filter cross sectional shape be the hexagon, the business turn over wind gap install in the casing both sides, inlet air channel in the casing and air -out path connection respectively have and to reduce the casing height under the prerequisite of guaranteeing filter area and reducing the heat loss, avoid the indoor suspended ceiling position to descend characteristics that the interior space that leads to the fact reduces.

Description

A kind of central air-conditioning Total heat exchange aeration device

Technical field

This utility model belongs to civilian central air-conditioning new wind devices field, particularly to a kind of central air-conditioning Total heat exchange aeration device.

Background technology

In order to adapt to central air-conditioning while regulation indoor temperature, the fresh of room air can be kept, in central air conditioner system, often add aeration device, in order to keep indoor temperature mostly to use Total heat exchange aeration device, such as Fig. 1, this device includes housing, filter, inlet and outlet, housing is used to support and install each functional part, filter is to ensure that the cleannes entering indoor air, and inlet and outlet is connected with blower fan and ventilation shaft；Fresh air enters in housing by air inlet, the opposite side of filter is entered by filter, entering indoor intake stack by air outlet and enter indoor, room air enters housing from indoor by air inlet from room ventilation pipeline side, through filter from air outlet discharge chamber；In order to reduce the heat loss of indoor, filter often uses the material of heat conductivility difference to make, in order to ensure filter effect, need certain filter area, have a disadvantage in that, existing filter cross-section is shaped as rectangle, its mounting means is as shown in Figure 1, owing to central air-conditioning Total heat exchange aeration device is arranged on above indoor suspended ceiling mostly, owing to the cross sectional shape of existing mounting means and filter determines, it is accomplished by reducing the bottom surface of indoor suspended ceiling, increase furred ceiling and can ensure the installation of central air-conditioning Total heat exchange aeration device to the distance on roof, indoor, therefore, owing to furred ceiling reduces, reduce the interior space, the sensation constrained to people.

Summary of the invention

The problem existed in an installation for existing central air-conditioning Total heat exchange aeration device, the utility model proposes a kind of central air-conditioning Total heat exchange aeration device, it is characterised in that: include housing, filter, inlet and outlet；Described housing is arranged on above house furred ceiling, between indoor suspended ceiling and roof；Described filter is arranged in housing；Described filter cross-section is shaped as hexagon；Described inlet and outlet is arranged on housing both sides, and air intake passage and air-out passage in housing connect.

Beneficial effect

The beneficial effects of the utility model are, it is possible on the premise of ensureing filter area and reducing heat loss, reduce body height, it is to avoid indoor suspended ceiling position declines the interior space caused and reduces.

Accompanying drawing explanation

Fig. 1 is the structural representation of existing central air-conditioning Total heat exchange aeration device

1. housing, 2. filter, 3. inlet and outlet.

Fig. 2 is structural representation of the present utility model

1. housing, 2. filter, 3. inlet and outlet.

Detailed description of the invention

In order to further illustrate the technical solution of the utility model, in conjunction with accompanying drawing, the detailed description of the invention that this use is detailed is described；Such as Fig. 2, according to installation method generally in the art, housing 1 is installed in the ventilation shaft of central air-conditioning, selecting cross sectional shape in this example is that filter that hexagonal and existing filtering material is identical is as filter 2, method generally in the art is installed be installed in housing 1 by filter 2, select inlet and outlet generally in the art as inlet and outlet 3, inlet and outlet 3 is arranged on the two ends of housing 1, just completes enforcement of the present utility model；Owing to have employed the filter 2 of hexagonal cross-section, reduce the setting height(from bottom) of housing 1；Such as Fig. 1, in this example as a example by the central air-conditioning Total heat exchange aeration device that height is 300 millimeters of existing filter 1, existing cross section be the setting height(from bottom) of foursquare filter 2 be 300 millimeters, its square length of side is 210 millimeters, single layer filter area is 48405 square millimeters, as used the cross section of same filter area to be, hexagonal setting height(from bottom) is less than 250 millimeters, in the case of ensureing that filter area is constant, greatly reduce the setting height(from bottom) of filter 2, so that the height of housing 1 reduces accordingly, the most just reduce the space requirement to house furred ceiling to top, house, the interior space will not be reduced.

Claims

1. a central air-conditioning Total heat exchange aeration device, it is characterised in that: include housing, filter, inlet and outlet；Described housing is arranged on above house furred ceiling, between indoor suspended ceiling and roof；Described filter is arranged in housing；Described filter cross-section is shaped as hexagon；Described inlet and outlet is arranged on housing both sides, and air intake passage and air-out passage in housing connect.
