Definitions

  • the present invention relates to a ventilation system for use in a food preparation area such as a commercial kitchen, and more particularly to a ventilation system in which hot air from cooking appliances is treated and returned to the food preparation area or to another area of the building where the food preparation area is located.
  • a commercial kitchen (such as a kitchen in a restaurant) normally includes an electric (or gas) cooking line, with several cooking appliances (such as ovens, griddles, burners, fryers and the like). These heat the air, introduce cooking odours into the air, and, particularly in the case of fryers, contaminate it with smoke, droplets of oil and grease, and the like. This heated and contaminated air needs to be removed in order for the kitchen to remain an acceptable working environment. Similar issues arise with other food preparation areas, such as bakeries.
  • hoods Removal of the heated and contaminated air is routinely carried out by means of purpose-made canopies or hoods above the appliances.
  • These hoods are normally provided with grease filters, and are connected to accessible ducts, usually located above the hood and running through the ceiling space to a dedicated fan set, which is normally positioned on the roof of the building in which the kitchen is located.
  • the fan is operated to discharge air from the ducts to the outside of the building, and this creates a lower pressure in the ducts which in turn helps evacuate the heated and contaminated air collected in the hoods.
  • a further problem with discharging the air to the atmosphere outside is that if all of the air sucked into the hoods were to be discharged in this way, this would result in a considerable fresh air make-up requirement to replace the discharged air. Further, heat in the discharged ⁇ ir is wasted, and the need to add heat to the make-up air in order to maintain a comfortable environment for the kitchen staff increases running costs. Normally, a small amount of the air (around 20 percent) is discharged, and the remainder is combined with make-up air / replacement air taken from the atmosphere, filtered, heated and returned to the kitchen; however, this still leads to wasted heat and increased running costs.
  • the need to provide ductwork to discharge air to atmosphere causes further problems.
  • the ducts will need to be located in risers, which imposes limitations on the possible layouts of the ductwork.
  • the ductwork in the riser will need to be made fireproof, increasing costs.
  • a ventilation system for cleaning contaminated heated air generated by cooking appliances in a food preparation area comprising: an inlet for contaminated heated air located in the food preparation area; a treatment part for cleaning contaminated heated air; and an outlet for the heated air; wherein the heated air is used as a heat source to heat the building in which the food preparation area is located.
  • the heated air can be used as a heat source in any suitable manner.
  • the outlet for the heated air is located in a region of the building which it is desired to heat.
  • the outlet for the heated air is located in a dining area associated with the food preparation area, and the heated air is used to heat the dining area.
  • Heated air generated by a food preparation area can be discharged from the outlet into the dining area to heat it, and there can be multiple outlets for the heated air to provide a more uniform heating effect.
  • Discharge can, in certain locations, take place at floor level.
  • the treatment part may be provided with means for cooling the air.
  • the temperature of the discharged air can be lower than the temperature of the air entering the inlet, to maintain acceptable comfort levels.
  • the hot air can be cooled in a direct exchange or chilled water cooling coil, connected to suitable heat injection equipment at roof level, before being discharged from the unit.
  • Air can be made to move through the treatment part in any suitable manner.
  • one or more fans are provided in the treatment part for creating a current of air from the inlet to the outlet.
  • the air can be cleaned in any suitable manner. However, it is preferred for the treatment part to clean the contaminated air by filtering it. Filtration is a well known method of cleaning air, and the filter or filters used can be tailored to the particular requirements of the installation.
  • a series of filters are used. This allows better tailoring of the filtration to the requirements of the installation, rather than relying on a single filter.
  • the ventilation system includes a monitoring system which monitors the state of the filters.
  • the installed life of the filters can be extended, as they will only be replaced when such replacement is actually necessary, rather than being replaced at specific times in accordance with a preset schedule.
  • the monitoring system includes transducers for measuring the pressure drop across the filters. As the filters become clogged, the pressure drop across them increases, and so the pressure drop across the filters allows the filter lifespan to be accurately determined.
  • the monitoring system can control the speed of the fan depending on the state of the filters. For example, if the monitoring system has noted that a filter is becoming clogged with contaminants and will soon need to be replaced, the speed of the fan can be changed (for example, increased to maintain a predetermined air flow) until such time as the filter is replaced.
  • the monitoring system may be connected to a display panel on the treatment part, and can switch on lights (such as an amber or red light), to indicate that a filter should be or must be replaced.
  • lights such as an amber or red light
  • the monitoring system can send wireless alerts depending on the state of the filters. This allows a person in charge of maintenance of the system to be alerted to the need to change a filter, even if the person is not near the treatment part at the time.
  • the monitoring system is accessible remotely. This allows a single maintenance operative to check on the state of the filters in several different installations from a single location, such as a central office.
  • the treatment part also includes means for removing odours from the contaminated air.
  • These can take any suitable form, but preferably include activated charcoal.
  • the treatment part is located in a room separate from the food preparation area.
  • the amount of space required in the food preparation area itself can be reduced.
  • maintenance of the treatment part may require the use of materials which should, ideally, be kept separate from food to prevent possible contamination of the food. Locating the treatment part in a room separated from the food preparation area allows maintenance to be carried out without the risk of such contamination, and without disturbing operations in the food preparation area.

  • the treatment part 200 of the ventilation system 10 includes a fan 210, which is operated to draw air through the treatment part from an inlet 220 to an outlet 230.
  • Figure 1 shows that the inlet 220 of the treatment part 200 is connected to ductwork 50 extending from the kitchen 20 through the wall 40 into the adjacent room 30, and this ductwork 50 in turn has one or more inlets 52 positioned above the cooking appliances 22, so that heated and contaminated air can be drawn into the ductwork 50 when the fan 210 is operated.
  • the outlet 230 of the treatment part 200 is connected to further ductwork 60 which extends away from the treatment part 200. All of the air entering the inlets 52 of the ductwork 50 above the cooking appliances 22 is drawn into the treatment part 200 by the fan 210, treated in the treatment part 200 (as will be described in detail later), and then passes through the further ductwork 60.
  • This further ductwork can be connected to an outlet in an area in the building that requires heating, so that the cleaned heated air can heat that area. There is thus no need for a route to the outside of the building, as would be required with a conventional system.

  • Each of the filters 242, 244, 246 can be replaced independently of the other two.
  • the first filter 242 will normally need to be replaced more frequently than the second filter, which in turn will need to be replaced more frequently than the third filter (for example, the first filter may need to replaced every month, the second filter may need to be replaced every three months, and the third filter may need to be replaced every six months.)
  • the first and second filters 242, 244 remove grease from the air which passes through them, and this grease will accumulate on the filters. If the design of the filter allows it, it may be possible to remove the accumulated grease and convert it into bio-fuel.
  • a monitoring system 250 (shown very schematically in the Figures) is provided to monitor the state of each filter 242, 244, 246, so that an alert can be sent to a user of the system when (oi:, more preferably, just before) each filter requires replacement.
  • the system may use pressure transducers to determine the pressure drop across the filters, as this pressure drop will vary depending on the state of the filter.
