The invention discloses a cleaning refrigerating
system, and relates to the related technical field of refrigerating systems. A solution
heat exchanger is included. The outer side of the solution heatexchanger is fixedly connected with a
refrigeration pipeline. One end of the
refrigeration pipeline is fixedly connected with one end of a condenser, and the other end of the
refrigeration pipeline is fixedly connected with one end of an
evaporator. The other end of the condenser is fixedly connected with one side of a first seal piece, and the other end of the
evaporator is fixedly connected with one side of a second seal piece. The invention further discloses a method of the cleaning refrigerating
system. The method comprises the steps that A, the refrigeration
system is stopped; B, a
dry ice machine is started, and a corresponding valve is opened; C, a high-pressure water tank and a corresponding valve are opened; and D, a cleaning water tank and a corresponding valve are opened. The
dry ice machine can be used for manufacturing
dry ice, after dry ice particles make contact with lubricating oil films and
dirt in heat exchange pipes and between various shell pipes, the phenomenon ofembrittlement explosion can happen, accordingly, the lubricating oil films and the
dirt can contract and loosen, and then instant gasification and swelling of dry ice particles happen.
