In that they use a compressor, dehumidifiers work the same way as air conditioners. As a result, they both use roughly the same amount of electricity, so your energy bill won’t be much different between them. However, it would be best to decide which one you want based on the environment you are trying to control. A dehumidifier is not a good idea if you live in very humid areas.

Air conditioners dehumidifiers
A dehumidifier can be used to remove humidity from a house. They are especially useful after heavy rains or in homes with little natural ventilation. They are more cost-effective than air conditioning systems, which require you to run a separate unit. Adding a dehumidifier to your home’s air conditioning system can help you save money on energy bills and increase comfort.
A dehumidifier draws water from the air and places it in a tank. Most dehumidifiers have a drain hose and an auto shut-off feature to prevent any spillages.
They work in the same way
Both air conditioners and dehumidifiers have the exact primary mechanism: they use a liquid or gas to move heat energy in and out of space. They also use the same method to remove humidity from a space. In both systems, the liquid or gas flows through a coil that draws moisture from the air.
Air conditioners use a condenser and evaporator to cool the air below the dew point. The heat is then released to the outside. Dehumidifiers, however, don’t need to use the condenser system. They pull the moistened air from the air and pump the air back inside. This also raises indoor temperature slightly.
They remove moisture from the atmosphere
A dehumidifier is an air conditioner that removes moisture from the air. The process of dehumidification involves using desiccant material that releases moisture when heated. The desiccant material is placed inside of a large drum that rotates and is made up of flat and corrugated sheets. A condenser is a large piece of plastic that condenses warm moist air. There are also disposable desiccants, or moisture adsorbers, which work well in smaller rooms.
A dehumidifier works with an air conditioner to reduce the amount of moisture in the air. This helps prevent the cooling system from working too hard and wasting too much energy. This can be used to make your home warmer or as an alternative to an air conditioner.
