Abstract
A method of supplying tempered makeup air to a room in conjunction with a grease extraction ventilator disposed above cooking equipment in the room and having removal means for removing grease and smoke particles and the like from air mixed with products of cooking, which includes removing heated air and the remaining products of cooking, after passage through the removal means, through a discharge duct; tempering fresh air in a heat exchanger and discharging the tempered fresh air into the room; passing incoming air to the discharge duct in a manner which automatically regulates the amount of exhaust and makeup air required to remove and replace the minimal amount of outside air to eliminate heat, odors, smoke, gases, grease and dirt as the cooking load changes; and causing incoming air, which is not passed to the discharge duct, to become a portion of the tempered air for discharge into said room. The removal means may be water contact means and there may be heat exchange, at least indirectly, between water from the water contact means with at least a portion of the fresh air. Control of the passage of incoming air to the exhaust duct may be inversely in accordance with the temperature of the heated air and products of cooking, such as measured adjacent the entrance of the exhaust duct and/or the entrance of the grease extraction ventilator. The apparatus corresponds to the method, but may further include an inlet duct for fresh air and a bypass duct between a fresh air plenum chamber and the exhaust duct.
