What are cyclic devices exactly?

    What are cyclic devices exactly? Are heat pumps and refrigerators both examples of cyclic devices? Also is a heat engine the same as a heat pump?

    A cyclic device is a device that operates by following some set cycle over and over again. Yes, heat pumps and refrigerators are cyclic devices.

    Is a heat engine the same thing as a heat pump?

    Lastly, are engines cyclic devices?

    No, A heat pump is a refrigerator. It uses work to move heat. A heat engine uses heat to produce work. An engine is too broad a term to answer.
