Poorly designed replacement air can create airflow disturbances and affect hood performance.<\/p>\n<h3 dir=\"auto\" data-section-id=\"f84isv\" data-start=\"19044\" data-end=\"19095\">Does a commercial kitchen need air conditioning?<\/h3>\n<p dir=\"auto\" data-start=\"19097\" data-end=\"19251\">The requirement depends on the application and climate, but cooling should be evaluated together with cooking heat, ventilation and replacement-air loads.<\/p>\n<h3 dir=\"auto\" data-section-id=\"ehep9h\" data-start=\"19253\" data-end=\"19313\">What is the difference between fresh air and make-up air?<\/h3>\n<p dir=\"auto\" data-start=\"19315\" data-end=\"19555\">Fresh air generally refers to outdoor air introduced for ventilation, while make-up air specifically refers to replacement air introduced to compensate for exhausted or consumed air. The two functions can overlap depending on system design.<\/p>\n<h3 dir=\"auto\" data-section-id=\"a7lthp\" data-start=\"19557\" data-end=\"19616\">What type of exhaust fan is used in commercial kitchens?<\/h3>\n<p dir=\"auto\" data-start=\"19618\" data-end=\"19894\">Centrifugal and axial exhaust fans are among the options used, with selection depending on airflow, pressure, temperature, ductwork and application. VIPUL lists both centrifugal and axial exhaust fans in its kitchen exhaust solutions.<\/p>\n<h3 dir=\"auto\" data-section-id=\"1a9ovs8\" data-start=\"19896\" data-end=\"19941\">How is kitchen exhaust airflow calculated?<\/h3>\n<p dir=\"auto\" data-start=\"19943\" data-end=\"20165\">The required airflow depends on factors including hood type, cooking appliances, cooking process and applicable design criteria. It should be determined through proper engineering rather than a simple kitchen-area formula.<\/p>\n<h3 dir=\"auto\" data-section-id=\"15wm88w\" data-start=\"20167\" data-end=\"20212\">Can kitchen exhaust be connected with BMS?<\/h3>\n<p dir=\"auto\" data-start=\"20214\" data-end=\"20344\">Yes.
