A laminated heat exchanger comprising a plurality of laminated plates, in which a plurality of heat transfer tubes bent into a zigzag form are arranged in contact with each surface of each of said plates, and said plates are laminated so that the heat transfer tubes on one of adjacent plates intersect with the heat transfer tubes on the other of the adjacent plates.
A refrigeration cycle having a primary loop in which a primary refrigerant circulates through a compressor, an outdoor heat exchanger, an expansion valve, and an intermediate heat exchanger and a secondary loop in which a secondary refrigerant circulates through said intermediate heat exchanger, a pump, and an indoor heat exchanger,
- wherein said intermediate heat exchanger has a plurality of plates and a plurality of heat transfer tubes which are bent into a zigzag form and are arranged in contact with each surface of each of said plates, said plates being laminated so that the heat transfer tubes on one of adjacent plates intersect with the heat transfer tubes on one of the adjacent plates.
A laminated heat exchanger comprising a plurality of laminated plates, in which a plurality of heat transfer tubes bent into a zigzag form are arranged in contact with each surface of each of said plates, and said plates are laminated so that the heat transfer tubes in contact with one surface of each of the plates intersect with the heat transfer tubes in contact with the other surface of each of the plates.
