Abstract
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.
Claims13
An air-ventilator comprising:
- a main housing, having first and second air-compartments along which first and second air streams respectively flow;
- first and second air-moving devices for moving said first and second air streams respectively along said first and second air-compartments;
- a thermal exchanger providing thermal exchange between said first and second air streams without mixing of said air streams;
- an air filter disposed at the upstream end of one of said air-compartments;
- and
- an additional air-moving device disposed in series with one of said air moving devices and intermediate said thermal exchanger and said air filter, to provide additional power to move air from said air filter towards said thermal exchanger.
An air-ventilator comprising:
- a main housing having first and second enclosed air-compartments along which first and second air streams respectively flow;
- first and second air-moving devices for moving said first and second air streams respectively in said first and second air-compartments;
- a thermal exchanger providing means for thermal exchange between said first and second air streams without mixing of said air streams;
- an air filter disposed at the upstream end of one of said air-compartments;
- an additional air-moving device disposed in said first air-compartment in series between said air filter and said first air-moving device, said additional air-moving device including means to substantially change the direction of the air-stream moving through it.
