<p>PROBLEM TO BE SOLVED: To reduce the total bulk relatively by arranging an air-current direction type first refrigerant path block through which passes air with a larger velocity and a counter air-current direction type second refrigerant path block through which passes air with a smaller velocity in combination. SOLUTION: In a first refrigerant path block 70, first-third refrigerant path inflow sections 61, 62 and 63 are installed on the side in the direction of an air current at the upper end of a heat exchanger 60 where air with a larger velocity passes. First- third refrigerant path outflow sections 61a, 62a and 63a are installed on the side in the counter direction of the air current at the upper end of the heat exchanger 60. In a second refrigerant path block 80, fourth and fifth refrigerant path inflow sections 64 and 65 are installed on the side in the counter direction of the air current at the lower end of the heat exchanger 60 where air with a smaller velocity passes. Fourth and fifth refrigerant path outflow sections 64a and 65a are installed on the side in the direction of the air current at the lower end of the heat exchanger 60. Thus, when the heat exchanger 60 combining an air-current direction type and a counter air-current direction type is applied for an evaporator and a condenser, the size thereof can be reduced considerably.</p> |
