PROBLEM TO BE SOLVED: To eliminate drain left in a drain pan, improve a drain characteristic, shorten a defrosting time and prevent a deformation of the drain pan caused by a freezing of residual drain. SOLUTION: A bottom plate 31 of a drain pan 30 is provided with ridge portions 34 and groove portions 35 extending in a longitudinal direction of the bottom plate 31 so as to cause drain to be collected at the groove portions 35. Then, the valley portions 35 are formed with drain pan heaters 21 extending in a longitudinal direction of the bottom plate 31. The drain pan heaters 21 are formed by heat transfer pipes and gaseous refrigerant of high temperature flowed from a compressor may flow in the pipes. The end section in the bottom plate 31 in a longitudinal direction is provided with a drain discharging hole 33 so as to cause drain flowed along each of the groove portions 35 to be discharged out of the drain discharging hole 33. |
