What is the maximum allowable temperature differential between makeup air and the air in the conditioned space in a commercial kitchen?

The maximum allowable temperature differential between makeup air and the air in the conditioned space for a commercial kitchen is primarily driven by the need to maintain comfort, efficiency, and effective ventilation. A temperature differential of 10°F helps ensure that the transitioned makeup air does not significantly disrupt the thermal balance of the kitchen environment.

When fresh air is introduced, especially in a high-activity area such as a commercial kitchen, it is crucial to manage how drastically the incoming air can vary in temperature from the existing conditioned air. A 10°F differential is deemed suitable for preventing discomfort and maintaining optimal indoor air quality. If the differential were too high, it could lead to drafts, heat stress on workers, and inconsistencies in the performance of heating or cooling systems.

This standard aims to balance operational efficiency and comfort by ensuring that the incoming air does not create a stark contrast with the conditioned air, which could adversely affect both equipment function and employee comfort levels while working in a demanding kitchen environment.
