Kitchen air supplement method and system

Abstract

The invention discloses a kitchen air supplement method. Fresh air is independently introduced from outdoors and directly sent to the two sides of an extractor hood, and the fresh air is not mixed with airflow in other spaces; cooking hot smoke plume is effectively protected by controlling air supplement on the two sides of the extractor hood, and the efficient trapping performance of the extractor hood is guaranteed; the micro negative pressure of the kitchen space is maintained to reduce the dissipation of cooking oil fume to the kitchen space, and the oil fume trapping effect of the extractor hood is improved; the air supplement speed is controlled to be 0.5 m / s or below; and the air supplement amount is controlled to be 50%-80% of the air exhaust amount. The introduced outdoor low-temperature fresh air is heated to avoid condensation in pipelines, and the damage of the outdoor low-temperature fresh air to the kitchen thermal environment is relieved. The invention further disclosesa kitchen air supplement system for realizing the method. According to the kitchen air supplement method and system, kitchen air supplement is organized, the problem that cooking oil fume escapes anddiffuses due to unorganized kitchen air supplementation is solved, and the trapping efficiency of the extractor hood is improved; and meanwhile, the air quality of a human body breathing area and thethermal comfort of cookers are improved.

Description

technical field [0001] The invention belongs to the technical field of indoor air conditioning, and relates to air replenishment technology, in particular to a method and system for replenishing air in a kitchen. Background technique [0002] Kitchen fume contains a large amount of pollutants. In addition to the irritating smell that can damage human mucous membranes and skin, a large number of toxic and harmful substances are "invisible killers" of human health. Research has found that cooking fume is associated with a higher incidence of lung cancer among non-smoking Chinese women. High is directly related. The health problems caused by kitchen fumes cannot be ignored. Kitchen fume pollution is mainly controlled by range hoods. However, in the early days, people paid too much attention to the exhaust air volume of range hoods, and did not guide the way of supplementing air, resulting in poor control of kitchen fumes and vicious competition in the air volume of range hoods...
