This invention provides a refrigerator. It includes a cabinet, a door, a refrigeration system, and a heat source. The refrigeration system includes a cabinet side portion, a door side portion, a first connecting pipe, and a second connecting pipe. The cabinet side portion is installed in the cabinet and has a compressor. The door side portion is installed in the door and has a first throttling device and a first evaporator. The inlet of the first evaporator is connected to the outlet of the first throttling device. One end of the first connecting pipe and one end of the second connecting pipe are respectively connected to the cabinet side portion at two locations on the cabinet side portion. The other end of the first connecting pipe is connected to the inlet of the first throttling device, and the other end of the second connecting pipe is connected to the outlet of the first evaporator. The heat source is configured to heat part or all of the first connecting pipe. Heating the first connecting pipe with the heat source reduces the risk of condensation on the exposed portions of the high / low pressure connecting hoses.
