With the energy intensity of commercial kitchens, there are some significant opportunities to recover waste heat, save energy and reduce your carbon footprint. The most obvious area to recover heat is the kitchen exhaust hood. The typical temperature coming off the exhaust collar is approximately 100⁰ F. Recapturing that heat has its challenges since the […]
Why are they different than non-solid fuel cooking operations and what are best practices when used with a Pollution Control System? As the name implies, Solid Fuel cooking operations are any cooking equipment that utilizes solid fuel for cooking the food product as opposed to using solid fuel for flavoring. Gas-operated equipment that uses solid […]
In today’s highly competitive labor market, restaurant owners need to find ways to differentiate themselves to attract and retain top talent to their teams. One way that’s often overlooked is the comfort of the working environment. For restaurants, this translates into improving the comfort of the kitchen. Not only does a hot kitchen drive down […]
What are the Requirements for automatically activating the exhaust ventilation system when the appliances are turned on?
The International Mechanical Code (IMC) provides the answers to the question. Chapter 507.1.1 Operations spells out the requirements for automatic activation of the exhaust system when appliances are turned on. If a kitchen ventilation system has demand ventilation controls, they satisfy the requirements. In the absence of such controls, other means need to be applied. […]
Thermal comfort is typically used when we are discussing how staff and customers feel in a restaurant and is typically evaluated using measures such as the temperature and relative humidity in the space. Indoor air quality is typically used to define how “clean” the air is that the staff and customers are breathing in a […]
A recent article in kitchenventilatio.com explored Food Hall and Mixed-Use Retail property kitchen ventilation design. These designs can be challenging in the best of circumstances and require detailed scope definition to ensure all elements are identified. Another aspect of Food Hall and Mixed-Use systems is that they lend themselves to shared or manifold grease exhaust […]
This article will provide the fundamentals of fan behavior, commonly known as “fan laws” in a system, and how a mechanical engineer selects the proper fan. Most manufacturers of fans have selection software that automates the selection process. The best advice to a Ventilation Engineer is to ensure that they are fully conversant with the […]
How to Manage Kitchen Ventilation in Heritage Buildings or Buildings with Limited Infrastructure space.
What is “Hybrid Recirculation” Kitchen Ventilation? It is a commercial kitchen ventilation system that incorporates recirculated air from an all-electric cooking process plus a conventional system serving gas/solid fuel-fired catering appliances carrying the need to discharge to the atmosphere. This dual approach enables the catering operator to still have the option to include certain items […]
Ok, I’ll admit, I made up the fancy title to pique the interest of the engineering crowd. It has a nice bio-medical ring to it. However, I thought it was somewhat appropriate, given that this article will be discussing the connections and control sequences for commercial kitchen ventilation (CKV) systems. Several components make up a […]
Vendor spaces in Food Halls or Mixed-Use Retail properties have significant logistical and infrastructure challenges. Creating spaces for foodservice operations before the vendor(s) have been identified while maintaining a high degree of infrastructure flexibility would be the goal, but often can fall short. Depending on the Food Halls or Mixed-Use property location, a secondary concern […]
