Ventilating and cooling apparatus

Abstract

Ventilating and cooling apparatus for cooking equipment heated by gas, oil, steam or electricity that reclaims radiant heat generated by cooking equipment by heat transfer panels through which cold water is circulated and preheated for use in hot water generating system or other system which can make use of preheated water. Heat transfer panels are positioned between the back edge of the canopy and the top of the cooking equipment and on the interior face of the canopy to collect radiant heat emitted directly and indirectly from the cooking equipment surfaces. An air passage behind the back panels serves to preheat incoming ventilation make-up air which is directed down, under and up along the front of the cooking equipment forming an air curtain and extracting heat from the body of the cooking equipment that is otherwise radiated to cooler bodies in close proximity to the heating surface. The flow of water through the panels is controlled by temperature regulating valves producing optimum temperature rise and flow. A pull down reflective shield positioned on the exterior of the leading edge of the canopy restricts the opening between the top of the cooking equipment and the leading edge of the canopy during prolonged cooking periods, reflecting radiant heat emitted directly and indirectly to the front but below the radiant heat panel on the interior face of the canopy back to the radiant heat panel at the back of the cooking equipment.
