The heat transferring unit includes a plurality heat transfer tubes. The canopy member includes at least one lateral side portion extending laterally outwardly and downwardly from a position above the refrigerant distribution assembly. The lateral side portion has a free end disposed laterally further from a vertical plane than the refrigerant distribution assembly, and lower than an upper edge of the outermost lateral end of the refrigerant distribution assembly.
