The present invention relates to a method for assembling a laundry dryer (32) including a heat pump system with a closed refrigerant circuit, said method comprises the steps of: providing components (12, 14, 16, 18) for the refrigerant circuit, wherein at least two components (12, 14, 16, 18) are coupleable by interconnecting a first end piece (26) and a second end piece (28) of refrigerant pipes (22); enlarging the first end piece (26) of the refrigerant pipe (22), so that the inner diameter of the first end piece (26) is marginally bigger than the outer diameter of the second end piece (28); deforming the enlarged portion of the first end piece (26) from the outer side, so that the second end piece (28) is coaxially insertable into the first end piece (28); inserting the second end piece (28) into the first end piece (28); and welding together the first end piece (26) and the second end piece (28). Further, the present invention relates to a laundry dryer (32) including a heat pump system with a closed refrigerant circuit. Moreover, the present invention relates to a heat pump system with a closed refrigerant circuit for a laundry dryer (32). |
