A compact air-ventilator with high efficiency thermal exchanger and air filter in which the thermal exchanger utilise a light-weight assembly of parallelly stacked thin metallic plates with pre-formed spaces. The high efficiency air filter includes a combination of filter elements including a mesh grid, an activated carbon layer and a HEPA filter. This air-ventilator can be built-in as part of an air-conditioner or as a stand alone unit to provide additional air circulating to conventional air-conditioners to improve indoor air quality. The thermal exchanger as well as the filters can be made with modular design to allow for easy periodic maintenance and replacement.

1. Field of the Invention
The present invention relates to an air-ventilating device, apparatus, system and/or installation. More particularly, this invention relates to an air-ventilating device, apparatus, system and installation having a thermal exchanger and an air filter. More specifically, this invention relates to an air-ventilating device, apparatus, system and/or installation which can be used in or with residential and commercial heating, cooling and air-conditioning systems or installations. This invention also relates to air conditioners having a built-in thermal exchanger and a high efficiency air filter.
A preferred embodiment of the present invention will now be explained by way of example and with reference to the accompanying drawings, in which:
FIG. 1 shows a schematic diagram of a preferred embodiment of an air-ventilator of the present invention with different arrows showing the different directions of air flow.
FIG. 2 is a top view of the air-ventilator of FIG. 1,
Referring to FIGS. 1-4, there is illustrated a preferred embodiment of an air-ventilator of the present invention. In the Figures, different arrows indicate the different directions of air flow within the air-ventilator. The air-ventilator (1) includes a main housing (2) inside which there are formed a first (10) and a second (20) enclosed air compartments or air chambers which respectively define a first and a second separated air-passageway. In this preferred embodiment, the first air-passageway (10) (illustrated by solid arrows) provides a “fresh air” path for outside air to enter the enclosed indoor space through the air-ventilator. The second air-passageway (20) (illustrated by broken arrows) provides an exit path (“exhaust air path”) for the indoor air to leave the enclosed space through the air-ventilator (1).
A thermal exchanger (30) is provided on the air-ventilator (1) at a position at which both air-passageways intersect without mixing. The thermal exchanger (30) provides means for transferring thermal energy between the incoming and the out-going air streams so that the total energy requirement for conditioning the air supply to the indoor space can be reduced.
Many types of heat exchangers are known. For example, the plate-type, the corrugated board type, the fin and tube-type and shell and tube-type heat exchangers. Plate-type heat exchangers are generally less complicated and more easily made and are therefore used in the present preferred embodiment for illustration purpose. Of course, other suitable types of heat exchangers can be used with suitable modifications and adaptations. The in-coming and out-going air streams are brought into thermal contact at the thermal exchanger to bring about thermal energy transfer between the two air streams before the indoor air leaves the enclosed space and the outside air enters the enclosed space.
