Rotary compressors are commonly used to power _______ refrigerated appliances such as window air conditioners, package terminal air conditioners and heat pumps up to 5 tons.

• A. Large
• B. Medium
• C. Extra large
• D. Small

Answer: (D)

Rotary compressors are a compact, cost-effective choice for smaller cooling loads. Their simple, positive-displacement design fits well in smaller refrigerated appliances, where space, weight, and cost matter. That’s why you’ll commonly find them powering window air conditioners, package terminal units, and compact heat pumps up to about 5 tons. For larger central systems, other compressor types are preferred because they handle higher capacities and efficiency demands better.
