How a dryer works

How a dryer dries depends largely on the type of dryer. Condenser dryers and air-dryers use an electric heating element combined with centrifugation – in which the dryer’s drum spins very quickly to squeeze moisture out of the laundry. Heat pump dryers have a heat pump and a refrigerant instead of the heating element. The heat pump converts the liquid refrigerant into gas form. This releases warm air, which heats the drum and your laundry. This method is a lot more energy efficient, making heat pump dryers cheaper to operate. However, the drying temperature remains relatively low, so it takes a little longer for your laundry to dry with a heat pump dryer. In addition, like the other types of dryers, a heat pump dryer also uses spin while drying.
