Use the material of the character that disproportionated reaction occurs as cold-producing medium with taking any measure, be not then only the possibility to become different materials
And no longer playing the effect of cold-producing medium, it is also possible to the pressure drastically owing to causing because of heating rises, and pipe arrangement rupture etc. occurs
Accident.This disproportionated reaction is particularly susceptible and occurs to there is the adjacent material of liquid and two-phase state etc. distance each other very near
The place of the material of liquid condition, but under gaseous state, if applying strong energy, then also there is disproportionated reaction.Therefore, in order to
Make cold-producing medium, need to try every possible means to prevent disproportionated reaction.The disproportionated reaction of cold-producing medium is owing to making cold-producing medium touch with structure
Hit or make current flow through the external energies such as cold-producing medium and occur.
[compressor 10]
Compressor 10 uses closed-type compressor.For example, High Pressure Shell formula or low-pressure shell formula, rotary compression are used
Machine or scroll compressor.Fig. 5 is the skeleton diagram of the structure of the compressor 10 of embodiments of the present invention 1.Fig. 5 is to see from side
Examine the side view of compressor 10.Compressor 10 shown in Fig. 5 is the rotary compressor of High Pressure Shell formula.Compressor 10 possesses:
The 42nd, the effuser that the 41st, pipe make cold-producing medium flow out from compressor 10 that flows into making cold-producing medium be flowed into compressor 10 compresses cold-producing medium
Compression unit the 43rd, as the motor 44 in driving source of compressor 10 and covering compression unit 43 and the closed container of motor 44 be
Compressor housing 45.Motor 44 configures the top at compression unit 43.
Motor 44 possesses stator 48 and rotor 49.Stator 48 is fixed on compressor housing 45.Rotor 49 configures at stator 48
Inner side, be linked to axle 50.Compression unit 43 possesses rotary plunger 51.Rotary plunger 51 is fixed in axle 50 as rotor 49,
The rotation of rotor 49 is passed to rotary plunger 51.Rotary plunger 51 is installed on axle 50 prejudicially.
In Figure 5.Solid arrow represents the direction that cold-producing medium flows.Cold-producing medium is flowed into compressor 10 from flowing into pipe 41,
The discharge chambe 47 being flowed into compression unit 43 via suction inlet 46.Discharge chambe 47 is being installed on the rotary plunger 51 of axle 50 prejudicially
Effect under, the volume accordingly of the rotation with rotary plunger 51 changes, to flow into cold-producing medium be compressed.Through overcompression
And the gas refrigerant of HTHP that pressure raises from discharge chambe 47 to compressor housing 45 in ejection, around motor 44
Flowing, flows out compressor 10 from effuser 42.
Here, the species of closed-type compressor has above-mentioned High Pressure Shell formula and low-pressure shell formula.Low-pressure shell formula is compressed
Machine 10 has compression unit 43 and motor 44 in the compressor housing 45 as closed container.It is inhaled into the compression of low-pressure shell formula
The cold-producing medium of machine 10 flows in compressor housing 45, becomes low pressure refrigerant environment in compressor housing 45.Compression unit 43
Discharge chambe 47 is for sucking the cold-producing medium in compressor housing 45 and compressing, after compression completes, from compression unit 43 to compressor
Housing 45 is outer discharges.In low-pressure shell formula compressor 10, such as compression unit 43 configures on top, and motor 44 configures in bottom.
In this low-pressure shell formula compressor 10, if making two phase refrigerant flow into compressor 10, then the liquid in two phase refrigerant becomes
Divided before being inhaled into discharge chambe 47, separated in the moment being flowed into compressor housing 45, under being configured at compression unit 43
Surrounding's flowing of the motor 44 in portion, drops to the bottom of compressor 10.Owing to the short liquid refrigerant of intermolecular distance is at motor
Surrounding's flowing of 44, therefore, is susceptible to disproportionated reaction, is in easily in the compressor housing 45 of low-pressure shell formula compressor 10
There is the state of the disproportionated reaction of cold-producing medium.
In addition, High Pressure Shell formula compressor 10 is constituted as previously described.Therefore, at discharge chambe 47 by compression
Become the gas refrigerant of high temperature, be discharged in the space i.e. compressor housing 45 that motor 44 exposes.The disproportionation of cold-producing medium is anti-
Should be susceptible under short liquid and two-phase state intermolecular, but disproportionated reaction is chemical reaction, it is commonly known that temperature
Spending higher, chemical reaction more easily carries out (reaction speed quickening).Therefore, even if cold-producing medium is gaseous state, as long as temperature is got over
Height, being more susceptible to disproportionated reaction, being in (although being less than low pressure shell in the compressor housing 45 of High Pressure Shell formula compressor 10
The degree of body formula compressor) it is susceptible to the state of the disproportionated reaction of cold-producing medium.
As described above, in the compressor housing 45 of low-pressure shell formula compressor 10, the short liquid refrigerating of intermolecular distance
Agent flowing around motor 44.In addition, be full of the gas of high temperature in the compressor housing 45 of High Pressure Shell formula compressor 10
Cold-producing medium.Therefore, no matter which kind of compressor 10 in the case of, all in the disproportionation being susceptible to cold-producing medium in compressor housing 45
The state of reaction.
In the compressor 10 as closed-type compressor, motor 44 is exposed to the refrigerant environment of low pressure or the system of high pressure
Cryogen environment.For stator 48 and the rotor 49 of motor 44, owing to there being electric current to flow, it is therefore desirable to carry out insulation processing.If no
Insulate motor 44, then electric current flows through the cold-producing medium of surrounding, does not only has the danger of electric leakage, it is also possible to because of electric current
Energy and make cold-producing medium generation disproportionated reaction.
As the insulating materials of motor 44, being preferably used will not physical because of cold-producing medium or chemically denaturation thing
Matter, particularly preferably uses the material with solvent resistance, resistance to extractibility, heat and chemical stability, resistance to foaminess.As motor 44
Insulating materials, have the insulating coating material of the winding of stator 48, insulation film, the insulator of holding winding, insulation tube etc., all
Resin material can be used.
Specifically, the insulating coating material of the winding of stator 48 uses polyvinyl formal, polyester, THEIC modified
One or more materials in polyester, polyamide, polyamidoimide, polyesterimide, imide.In addition, also
Coat of paint more than 120 DEG C for the vitrification point can be used.
In addition, the insulation film of stator 48 uses polyethylene terephthalate (PET), poly-naphthalenedicarboxylic acid ethylene glycol
One or more materials in ester, polyphenylene sulfide (PPS), polybutylene terephthalate (PBT) (PBT).Insulators etc. keep winding
Insulating materials use from polyether-ether-ketone (PEEK), liquid crystal polymer (LCP) selection one or more materials.Paint uses ring
Epoxy resins.Further, the insulation tube of stator 48 uses from polytetrafluoroethylene (PTFE) (PTFE), hexafluoropropylene (HFP)/tetrafluoroethylene (TFE) copolymer resins
(FEP) one or more materials selecting in.
Additionally, as previously described, even if cold-producing medium is gaseous state, as long as temperature raises, then compression case
It is at being susceptible to the state of disproportionated reaction in body 45.Disproportionated reaction is that temperature is higher, and reaction more easily carries out (reaction speed
Accelerate), especially more than 50 DEG C at a temperature of, be susceptible to the disproportionated reaction as chemical reaction.There is High Pressure Shell
In the refrigerating circulatory device of formula compressor 10, when the temperature of the cold-producing medium in the compressor housing 45 of compressor 10 is except starting
Outside transition state, in most cases, it is all temperature more than 50 DEG C.But, in this condition, as long as carrying out above-mentioned
The insulation of the motor 44 of such compressor 10, it is also possible to the disproportionated reaction of suppression cold-producing medium.Additionally, in the state of 80 DEG C,
It is easier to disproportionated reaction.
Here, consider would indicate that having the refrigerator oil of intersolubility with cold-producing medium is used in kind of refrigeration cycle.Cold-producing medium phase
For the solubility of refrigerator oil of intersolubility under the conditions of uniform pressure, temperature is lower, and solubility is bigger, in identical temperature strip
Under part, pressure is higher, and solubility is bigger.If cold-producing medium is dissolved in refrigerator oil, then the molecular melting of refrigerator oil being present in
Between the molecule of cold-producing medium and molecule.That is, if cold-producing medium is big relative to the solubility of refrigerator oil, then refrigerator oil can be present in
Between the molecule of more cold-producing medium and molecule.The disproportionated reaction of cold-producing medium is showing of reacting with each other of the molecule of adjacent cold-producing medium
As with cold-producing medium there is the refrigerator oil of intersolubility if using, then there is refrigerator oil between the molecule of cold-producing medium and molecule
Molecule, therefore, the disproportionated reaction of cold-producing medium becomes more difficult to occur.
In order to suppress the disproportionated reaction of cold-producing medium, cold-producing medium is bigger relative to the solubility of refrigerator oil, and effect is better.?
In practicality, in the case that cold-producing medium is liquid condition or two-phase state, if cold-producing medium is relative to the dissolving of refrigerator oil
Degree is more than 50wt% (weight %), then more cold-producing medium is dissolved in refrigerator oil, therefore, it is possible to suppression disproportionated reaction.Cause
This, in the case of using low-pressure shell formula compressor 10 as compressor 10, such as the cold-producing medium in compressor housing 45
In the state of the temperature that temperature is 0 DEG C and pressure is cold-producing medium is saturation pressure when 0 DEG C, if cold-producing medium is relative to refrigerator
The solubility of oil is more than 50wt% (weight %), even then two phase refrigerant flows into, it is also possible to fully suppress cold-producing medium
Disproportionated reaction.
Additionally, as described above, in the case that cold-producing medium is liquid condition or two-phase state, be easiest to occur disproportionation anti-
Should.Even if in addition, cold-producing medium is gaseous state, in the state of temperature height, the shape of especially more than 50 DEG C and then more than 80 DEG C
It under state, is susceptible to the disproportionated reaction as chemical reaction, but in the case that cold-producing medium is liquid condition or two-phase state, more
It is susceptible to disproportionated reaction.Although the cold-producing medium of gaseous state is also dissolved in the refrigerator oil of intersolubility, but is used for suppressing high temperature
The solubility required for disproportionated reaction of gaseous state can be less than the value of liquid condition or two-phase state.In practicality,
In the case that cold-producing medium is gaseous state, if solubility is more than 10wt% (weight %), then can fully suppress high temperature
The disproportionated reaction of cold-producing medium of gaseous state.Therefore, the situation as compressor 10 for the High Pressure Shell formula compressor 10 is being used
Under, such as the temperature that the temperature of the cold-producing medium in compressor housing 45 is 80 DEG C and pressure is cold-producing medium is saturation pressure when 50 DEG C
In the state of power, if cold-producing medium is more than 10wt% (weight %) relative to the solubility of refrigerator oil, then can fully press down
The disproportionated reaction of cold-producing medium processed.
In addition, the refrigerator oil of present embodiment uses the bigger refrigerator oil of specific insulation.For example, refrigerator oil
Specific insulation be 2 × 10 when 20 DEG C10More than Ω m.Therefore, if using the oil that dissolves each other as refrigerator oil, then compressor
Cold-producing medium in the compressor housing 45 of 10 is of a relatively high value with the specific insulation of the fluid-mixing of refrigerator oil.Cause
This, in compressor 10, fewer from the leakage current of motor 44 leakage, it is more difficult to the disproportionated reaction of cold-producing medium occurs.
Additionally, as refrigerator oil, use with any composition in polyol ester and polyvinylether as main component is cold
Freeze machine oil.Polyol ester and polyvinylether be all that specific insulation is higher, have easily to be dissolved in and have in the molecular structure
The refrigerator oil of the intersolubility of the cold-producing medium of one double bond.
In addition, in the present embodiment, with in the compressor housing 45 at compressor 10, compression unit 43 be positioned at lower section, electricity
It is illustrated in case of machine 44 is above, but be not limited to this.Also can be that compression unit 43 is above, motor
44 are positioned at lower section.Either High Pressure Shell formula compressor or low-pressure shell formula compressor, this point is just as.
It in addition, be illustrated in case of compressor 10 is rotary compressor, but is not limited to this, it is possible to
To use the compressor of any mode such as scroll compressor or screw compressor, identical effect can be obtained.
