PROBLEM TO BE SOLVED: To make it possible for there to be a heat pump type hot-water supplier which has no dead space, is compact, and effects heat exchange with good efficiency. SOLUTION: A plate type heat exchanger 16 comprises water-passageway plates 11, refrigerant-passageway plates 12, and partition plates 13 which are all uniformly shaped and laid one plate over another alternately. The plate surface can be made use of effectively and a long flow passageway can be formed thereon so that lessening of dead space and compactness of the plates themselves enable achieving considerable structural compactness and improvement of the heat exchange efficiency. |
