What is a primary concern when refrigerants leak into the building space?

When refrigerants leak into the building space, a primary concern is the potential health hazards they pose to occupants. Many refrigerants can be toxic or harmful if inhaled, and exposure can lead to various health issues, including respiratory problems and other serious health effects. In enclosed spaces, even small leaks might elevate the concentration of dangerous substances to levels that could be detrimental to human health.

While increased operational costs, reduced cooling efficiency, and increased energy consumption are valid concerns related to refrigerant leaks, they are secondary to the immediate risks posed to health and safety. Addressing health hazards is crucial in ensuring a safe environment for occupants, making it the most pressing concern in this scenario.
