Abstract
A ventilating, cooling, and heat reclaiming system for use with cooking equipment such as commercial ranges and grills whereby grease laden exhaust air passes through a grease filter or extractor and then past a cooling coil through which water is circulated so as to improve grease removal and reclaim heat from exhaust air to heat outdoor supply air. The heated water from the coil is supplied to a further coil disposed in the path of outdoor supply air via a three way valve having two outlets and a mixing valve. The mixing valve varies temperature of water in the further coil to maintain constant the temperature of the supply air and water not supplied to the further coil is supplied to a hot water generator by the three way valve.
Claims8
A venting and cooling system for use with cooking equipment comprising:
- first duct means defining a supply passage for supplying fresh air to the vicinity of the equipment,
- second duct means defining an exhaust passage for exhausting air from the vicinity of the equipment,
- filter means disposed in said exhaust passage for removing particulate matter and droplets from the exhausting air,
- a cooling coil disposed in said exhaust passage for cooling the exhausting air to improve removal of said particulate matter and droplets,
- means connected to said cooling coil for supplying a fluid to said cooling coil at a temperature below the temperature of said exhausting air,
- a further coil disposed in said supply passage for changing the temperature of said supply air,
- means connecting said cooling coil to said further coil for supplying the fluid leaving said cooling coil to said further coil, and
- valve means disposed in said connecting means for controlling flow of said fluid from said cooling coil to said further coil.
