What is typically not covered by the EPA’s definition of an appliance?

The EPA's definition of an appliance generally encompasses equipment used for cooling and refrigeration in residential and commercial settings, such as air conditioning systems and refrigeration units. However, devices designed exclusively for military use fall outside of this definition. This is primarily because military devices often have specialized applications and stringent requirements that cater to unique circumstances, which are significantly different from standard appliances used in civilian life. Thus, they do not fall under the general guidelines or regulations set by the EPA for typical household or commercial appliances.

In contrast, air conditioning systems, refrigeration units for home use, and commercial chillers are all included in the EPA's definition because they are widely used for temperature control and refrigerant management in everyday environments. These categories of appliances must adhere to specific environmental regulations concerning refrigerant management and emissions, highlighting their relevance within the EPA's framework.
