Heat pump dryers are recent crossovers from the European to the North American market. They're energy-efficient, compact and ...

The heat pump dryer then uses a second loop to cool the air, condensing the water out so the it can reheat the air and start the whole cycle over again. Where does the water go? Depends.

“This heat pump concept is effective with water as ... The system uses a compression refrigeration cycle that moves hot compressed gas from the compressor to the condenser, which then releases ...

Heat pump heating technology is ... first person on record to demonstrate artificial refrigeration. The power needed to run the compressor pump and control gear is usually electrically derived ...

The novel heat pump system relies on a thermal sensor based on an adsorbent-coated sensor layout developed by Vaillant in ...
