Apparatus and method for exhaust gas dispersion and condensate removal for gas engine driven heat pumps

A gas engine driven heat pump system including an apparatus and method for exhaust gas dispersion and condensate removal which disperses and mixes exhaust gases more effectively to prevent local icing, inhibit frosting of outdoor heat exchangers, reduce engine noise, and mask exhaust odors, and which removes and treats condensate to further inhibit frosting and corrosion. Dispersion and condensate removal are achieved with exhaust gas distribution and condensate draining features incorporated into the exhaust system of the present invention, and with a fan compartment structure which promotes more complete mixing of exhaust gases and ambient air, while housing both the exhaust system and the outdoor heat exchanger.

Exhaust gas treatment device

Exhaust emission control device

An exhaust emission control device includes a single filter assembly composed of a pair of side plates respectively formed in an L-letter shape in cross-section and integrally assembled in a square framework having inlet and outlet openings, and a plurality of ceramic filter elements aligned in parallel within the square framework and clamped by the side plates. The filter elements are each made of porous ceramic material and have a thin-walled cellular structure square in cross-section formed with a plurality of axially extending passages separated from each other by thin partition walls, wherein a first group of the passages are closed at their one ends in a checked pattern and opened at their other ends to introduce therein exhaust gases to be purified, while a second group of the passages are opened at their one ends to discharge purified gases therefrom and closed at their other ends in a checked pattern.
