The cooking zones of restaurant kitchens are bad heat traps, where the temperatures surrounding a busy grill reach as high as 105° to 110° Fahrenheit. The kitchen space needs to have a system in place to combat this sweltering heat. The best way is to merge ventilation, air circulation, and hydration. An appropriate HVAC offers a good foundation.
LG duct split system allows zoning flexibility, which can also be a good way to reduce the heat strain of kitchen staff and refrigeration system.
Exhaust venting system
Kitchen fumes, smoke, heat, and particulates get sucked inside the exhaust hood, exit through the vents, and get blown outdoors through fan system. An equal percentage of make-up or replacement air from outdoors gets drawn inside the kitchen via make-up air vents.
This makes the air conditioning system to work at optimum level. Correct venting system keeps you in compliance with strict local, state, or federal standards. Consider ventilation fans with variable speeds to reduce power consumption, when time is less busy.
Kitchen air that exhausts outside gets replaced with make-up air from dining room, properly screened open doors, or windows. Screens help to prevent pests and insects from plaguing food preparation zones.
If the kitchen is exposed to direct sun then install shutter or shade on the windows to reduce heat level. To allow cool fresh air flow inside the kitchen keep doors open later after sunset and early morning.
Keep HVAC clean
To maintain the performance of your HVAC system, it needs to be kept clean always. In addition, the coolness level will be compliant with fire safety and health department regulations.
Replace filters and ducts as required. Keep check of dust, grease or grime buildup through entire system. Monitor room temperatures and if any unusual number gets flashed then it is a sign of developing issue.
Ductless for extra kitchen cooling
Ductless system is just like the central system with two units’ compressor/condenser for outdoors and air handling unit installed in zones to be kept cool. Both units are linked with a conduit that comprises of refrigerant tubing, power cable, condensate drain, and suction tubing. The advantage of Mitashi ductless split system over central cooling system is –
- Easy installation
- Zoning and design versatility
- Functions silently
- No ductwork
- Eliminates the issue of cool air loss through lengthy ductwork
Duct split systems are costly but make sure to select the proper sized unit and position it properly to take advantage of its cooling potential.
Auxiliary fans will not hinder with the functions of exhaust fans. The fans need to be aimed away from the hot food pick up areas and even the prep tables because blowing air can scatter lighter food items. Window fans faced in to bring cool breeze or out to eliminate hot air can be helpful but ensure to keep boxes, fan-guards, and the blades free from dust.
Educate staff to avoid dehydration
Let them get familiar with signs of illness related to heat like dizziness, nausea, and headache along with ways to avoid it. Encourage the kitchen staff to drink lots of water to hydrate and not dehydrating caffeine beverages. A wilting staff member can visit the walk-in-cooler for two minutes and revive.
