In a closed room, where does the heat go?
Dehumidifiers and air conditioners condense moisture using the same principle, but they handle the recovered heat differently.
🌀 Dehumidifier No outdoor unit
Indoor air intake
↓
Moisture condensation at the evaporator
↓
Condenser releases refrigerant heat
↓
Returns directly into the room
❄️ Air conditioner Has an outdoor unit
Indoor air intake
↓
Moisture condensation at the evaporator
↓
Refrigerant travels through pipes to the outdoor unit
↓
Released into the outdoor atmosphere
A dehumidifier's power consumption is about 300~400Wh per hour — all of this power turns into heat and remains in the room. It generates heat similar to having a small electric heater turned on.
