Question 56Refrigeration & AC - 1st Asst/Chief

The correct answer is D) 0.91 kg (2 lbs) of refrigerant. According to the EPA Regulations Section 608, a "Type I" small refrigeration appliance is defined as a system that is manufactured and hermetically sealed, with a capacity of 2 pounds (0.91 kg) or less of refrigerant. This is the key criteria that distinguishes a Type I appliance from the other types of refrigeration systems mentioned in the answer choices. The other options are incorrect because they do not accurately define the specific refrigerant capacity that characterizes a Type I appliance under the EPA regulations.
