What are the differences between condenser drying and heat pump drying?

Please refer to the following information about the differences between condenser drying and heat pump drying:
1. Condenser dryers work by absorbing moisture from wet clothes and converting it into water inside the machine. Unlike traditional dryers that vent hot, humid air outdoors, they cool the humid air inside the drum, causing water vapor to condense into liquid water, which is then collected or discharged. This method requires no external vents, operates at a temperature of approximately 60-70 °C, is less gentle on sensitive fabrics, and is less frequent; therefore, condenser dryers are preferred.
2. Heat pump dryers achieve air heating and dehumidification through a refrigerant compression, condensation, expansion, and evaporation cycle. The compressor heats the air before it enters the drum, causing the moisture in the clothes to evaporate. The humid air is then cooled and dehumidified, and the dry air is recycled. Heat energy is continuously recovered and not released outdoors. The drying temperature is approximately 40-60 °C, which is gentler on clothes and saves about 40-50% more energy than condenser dryers. For frequent clothes drying, heat pump dryers are the preferred choice.
