| PROBLEM TO BE SOLVED: To improve reliability by removing a foreign matter, such as wear powder, in a refrigerating cycle, in a refrigerating cycle when especially an HFC refrigerant is used. SOLUTION: Connection pipings 1 are arranged at the front and the rear of the throttle part 2 of a refrigerating cycle. The connection pipe 1 has a curvature, a fine tube 3 is extended from the outermost part of the curvature, and the fine tube 3 is coupled to a capturing part 4 to capture a foreign matter in the refrigerating cycle. The foreign matter in the refrigerant is separated from the refrigerant by a centrifugal force and captured by the capturing part 4. Further, by disposing a magnetic substance 5 in the capturing part 4, the capture effect of the foreign matter is improved. COPYRIGHT: (C)1997,JPO | ||||||

| PROBLEM TO BE SOLVED: To enable corrosion at a capillary tube or clogged state caused by adhesion of sludge to be reduced. SOLUTION: Since an inner surface of a capillary tube 5 is formed by a coating film 5M of anti-wear material, even in the case that mixed refrigerant, in particular, refrigerant of HFC system is used, it is possible to reduce friction or wear caused by corrosion at the capillary tube 5. In addition, owing to a presence of the coating film 5M of the anti-wear material, the sludge is hardly adhered to the tube and its clogging is reduced. | ||||||

| PURPOSE: To provide a freezer in which adhering and accumulated substances having as a major substance wax are not generated at an inner wall of a capillary tube by a method wherein the capillary tube connected to a cycle tube is heated and the other end of the capillary tube is connected to an evaporator. CONSTITUTION: As refrigerant is heated within a compressor 7, wax mixed in a freezing cycle is melted. This melted wax is circulated in sequence together with the refrigerant through a condensor 8, a cycle tube 3 and a capillary tube 1. A part near a connected part between the capillary tube 1 and an evaporator 2 shows a quite low temperature, so that the wax at its melted state is adhered and accumulated within the capillary tube 1 and a clogged state occurs at the capillary tube. In this case, if the capillary tube 1 is heated with a ribbon heater 4, for example, the wax adhered and accumulated within the capillary tube 1 can be melted and then removed to the evaporator together with the refrigerant. | ||||||

| PURPOSE: To execute automatic cleaning of a filter which is used for taking in outside air that cools a condenser, by detecting clogged state of the filter. CONSTITUTION: In an condensing unit for executing forced cleaning of a condenser 1 by sending outside air through a filter 3 by means of a cooling fan 2, pressure drop caused by clogging of the filter 3 is detected by a pressure sensor 5 which is mounted just behind the filter 3 and when the pressure drop reached to the predetermined level, the filter 3 is made to slide by a motor 4, between air passage surfaces 3a and 3b of the filter 3, one surface that has not been used being set to usage status and clogged surface of them being subjected to blow of cleaning water which is ejected from pump devices 6 or 7.
