PURPOSE:To assure uniform air temperature distribution and reduce pressure loss by installing two each of adjoining inlet and outlet headers, arranging alternately refrigerant pipes starting out and terminating at respective headers and setting the center of the inlet and outlet of an evaporator on a same axis. CONSTITUTION:Refrigerant pipes 18 in an evaporator 9 are divided into a refrigerant pipe 18 starting from a refrigerant inlet header 201 and terminating at an adjoining refrigerant outlet header 211 and a refrigerant pipe starting from a refrigerant inlet header 202 and terminating at an adjoining refrigerant outlet header 212. An arrangement of the refrigerant pipes as described herein makes the temperature of air as a whole uniform, which was put through heat exchange with each refrigerant pipe. Next, the centers C1, C0 of the inlet and outlet openings of the evaporator 9 are adjusted to be on a same axis. The pressure loss arising from the construction of a casing 14 here becomes smaller as compared with the pressure loss in a case where the center C1 of an inlet opening 22 and the center C0 of an outlet opening 23 are not on a same axis. |
