Humidity often needs to be removed from the conditioned air in the _______________ mode.

The removal of humidity from conditioned air is primarily associated with the cooling mode in HVAC systems. When air conditioning systems run in cooling mode, they not only lower the temperature of the indoor air but also dehumidify it. This process occurs because as warm air passes over the cold evaporator coils of the air conditioning unit, moisture in the air condenses on the coils. This condensation effectively removes humidity, ensuring that the indoor environment is comfortable and free of excess moisture, which can lead to problems such as mold growth and discomfort.

During the heating mode, while some moisture may still condense depending on the conditions, the primary goal is to raise the air temperature rather than actively remove humidity. The ventilating mode focuses on bringing in or circulating air but does not specifically target humidity levels. Lastly, the humidifying mode emphasizes adding moisture to the air, which is the opposite of what is needed for humidity removal.
