摘要： PROBLEM TO BE SOLVED: To ensure reliability over a long period of time by eliminating from the refrigerating system extraneous matter such as dust, metal powder, machine oil, and carboxylate. SOLUTION: The number 12 in diagram indicates a capillary tube which seizes extraneous matter such as dust, metal powder, machine oil, and carboxylate. First and second copper pipes 13, 14 are connected to the capillary tube 12, the one on the side of a dryer 6 and the other on the side of an indoor heat exchanger 9 respectively. The first and second copper pipes 13, 14 are connected respectively to a system piping 15 on the side of the dryer 6 and to a piping 16 on the side of the indoor heat exchanger 9 in a manner of being detachable and replaceable. Moreover, first and second valves 18, 19 which each can stop a flow of refrigerant are set, the first valve in the system piping 15 on the side of the dryer 6 and close to the first copper pipe 13 and the second valve in the system piping on the side of a four-wave valve 3 for the indoor heat exchanger 9. This constitution permits the capillary tube 12 to be replaced in a simple manner and enables obtaining an air conditioner which ensures reliability over a long period of time.

摘要： PROBLEM TO BE SOLVED: To secure stability of the performance of a refrigerating cycle over a long period of time in the case where use is made of a refrigerant containing hydrofluorocarbon and a refrigerating machine oil of polyol ester as working mediums by disposing a mechanism for scavenging organic acids and free metallic ions. SOLUTION: A mechanism for scavenging organic acids and free metallic ions is disposed in a refrigerating cycle. To put it in detail, the mechanism has a structure combining a moisture absorbent, a weakly basic ion exchange resin, and a chelating resin, that is, for example, the moisture absorbent 7 in beads, the ion exchange resin 8 in beads, and the chelating resin 9 in beads are stuck in a mesh 10 and placed in a container 11 which permits the passage of working fluid. In a refrigerating cycle having a refrigerating compressor, condenser, expansion mechanism, and evaporator each equipped with such a scavenging mechanism 12 for organic acids and free metallic ions the performance can be stabilized over a lond period of time.

摘要： PROBLEM TO BE SOLVED: To eliminate dissolved gas in a refrigerator with a high efficiency by foaming dissolved gas in refrigerating machine oil by bringing the refrigerating machine oil into contact with a material having needle shaped or projection shaped structure while carrying out vacuum-exhaust in a refrigerating compressor in which the refrigerating machine oil is filled. SOLUTION: In the case adapted to a compressor of a vertical scroll type, a needle or projection shaped structure 10 is arranged below a liquid surface of a refrigerating machine oil 12 filled in the compressor. The refrigerating machine oil 12 and the structure 10 are brought into contact with each other while carrying out vacuum- exhaust in the compressor filled with the refrigerating machine oil 12, and small bubbles made of dissolved gas in the refrigerating machine oil 12 are generated following with change of pressure condition in the refrigerating machine oil 12, and are generated at an interface between the refrigerating machine oil 12 and the structure 10 according to a contact surface area. The small bubbles are absorbed each other, and are grown so as to accelerate foaming of dissolved gas in the refrigerating machine oil 12. It is thus possible to eliminate dissolved gas with good efficiency so as to carry out deaeration.

摘要： PROBLEM TO BE SOLVED: To prevent jams of a capillary tube and a filter, and generation of copper plating phenomenon in a compressor by using a sintered metal raw material in one part or all parts of a constituting element having a surface which is brought into contact with a refrigerating machine oil at the time of non-operation, in the compressor. SOLUTION: A sintered metal raw material is used in one part or all parts of a surface of a constituting element of a compressor such as a scroll type and the like having a surface which is brought into contact with a refrigerating machine oil. Air remaining in an opening air hole made of the sintered metal raw material is deaerated by passing into the refrigerating machine oil. The air to be deaerated is treated in such a way that the air is delivered outside the refrigerating machine oil following with moisture and oxygen which are dissolved in the refrigerating machine oil. Therefore, the moisture rate and the oxygen rate in the refrigerating machine oil are reduced more than that of a prior art, and jams of a capillary tube and a filter and the like are prevented in the case where a substitutive refrigerating machine oil such as substitutive refrigerant, ester oil, ether oil, carbonate oil, and the like is used.

摘要： PROBLEM TO BE SOLVED: To exchange oil, absorbing a moisture content entering a refrigerating cycle during a site installation work and maintenance, with new oil without releasing a system. SOLUTION: An oil container 14 to perform exchange of oil 17 in an air- conditioner is removably connected through three-way valves 12 and 13 to the middle of an oil return piping 11 through which the oil reservoir part of an oil separator 2 is coupled to a piping 10 on the suction side of a compressor 1 through a throttle 9. After completion of arrangement or maintenance, cooling continuous operation or heating continuous operation is carried out as a trial run and thereafter, by switching the three-way valves 12 and 13, an oil 17 absorbing a moisture content in a refrigerating system is replaced with a new oil 17 in the oil container 14. This constitution improves reliability of an air- conditioner.
