Portable Unit

A dehumidifier is generally a household appliance which reduces the level of humidity in the air, usually for health or comfort reasons, or to eliminate dank smells.

Dehumidifier

A heat pump is an air conditioner that contains a valve that lets it switch between "air conditioner" and "heater “. When the valve is switched one way, the heat pump acts like an air conditioner, and when it is switched the other way, it reverses the flow of the liquid inside the heat pump and acts like a heater.
