Abstract
The invention discloses an oil-containing refrigerant and a production process thereof and relates to maintenance of refrigeration equipment. The oil-containing refrigerant mainly comprises a pressure container and a mixture of the refrigerant and lubricating oil, and the mixture is sealed in the pressure container. As for air conditioning, refrigeration and other equipment with mechanical compression mechanisms, when leakage failure occurs, the lubricating oil can also leak along with the refrigerant, thereby causing the loss of the lubricating oil in a refrigeration pipeline system. After a repairman repairs the failure, the refrigerant has to be emptied due to the process need of supplementing and adding the lubricating oil, the inside of the refrigeration pipeline system needs to achieve a certain degree of vacuum, and then the lubricating oil can be conveniently supplemented and added, thereby causing the waste of the refrigerant and the lubricating oil and further exacerbating the environmental pollution. The invention aims at directly supplementing and adding the refrigerant and the lubricating oil without using the vacuum-pumping maintenance process flow under the situation that the refrigerant is arranged in the refrigeration pipeline system, simplifying the maintenance process, reducing the maintenance cost and further reducing the environmental pollution.
Description
Technical field
The present invention relates to the refrigeration plant maintenance.
Background technology
Artificial atmosphere, refrigeration waits these to have the equipment of mechanically compress mechanism, be used for refrigerating refrigeration agent and the lubricating oil that is used for compressor lubrication, all be in the piping system of a sealing and circulate, lubricating oil and refrigeration agent have certain mutual solubility, when the seepage fault appears in the piping system of sealing, in the refrigeration agent seepage, lubricating oil is also along with refrigeration agent seepage together, cause lubricating oil disappearance in the refrigeration pipe system, cause compressor lubrication bad, influence the work-ing life of compressor or directly make compressor produce fault, also make refrigerating efficiency decline, particularly automotive air-conditioning system, because the compressor power input shaft end is in the dynamic seal state, because working condition is abominable relatively, more be easy to generate such seepage fault again.The repairman is after repairing this class fault, because replenish the arts demand that adds lubricating oil, necessary flare refrigerant, with the refrigeration pipe system pumping with exhaust blower, make the vacuum that reaches certain in the refrigeration pipe system, could conveniently replenish then and add lubricating oil, like this, make the interior remaining cold-producing medium of refrigeration pipe system comprise that its interior lubricating oil of dissolving all is discharged into (because of the cost recovery height) in the environment, except wasting cold-producing medium and lubricating oil, increase maintenance cost, also aggravates environmental pollution.Purpose of the present invention, be in order to overcome the deficiencies in the prior art, a kind of refrigerating agent containing oil and production technique thereof have been invented, in refrigeration pipe system, have under the situation of refrigeration agent, need not to use the maintenance process flow process that vacuumizes, just can directly replenish and add refrigeration agent and lubricating oil, simplified maintenance process, reduce maintenance cost, also reduced environmental pollution.
Summary of the invention
The objective of the invention is in order to overcome the defective of above-mentioned prior art, a kind of refrigerating agent containing oil and production technique thereof are provided, can solve the waste refrigeration agent of above-mentioned existence and lubricating oil, increase maintenance cost reliably, problems such as aggravation environmental pollution, simplified maintenance process, reduce maintenance cost, also reduced environmental pollution.
Technical scheme of the present invention is: a kind of refrigerating agent containing oil, mainly form by the mixture of sealed refrigerant and lubricating oil in pressurized vessel and the pressurized vessel.
Described pressurized vessel is the pressurized vessel of the general corresponding refrigeration agent of can, the refrigeration agent difference of institute's can, and the requirement of withstand voltage of pressurized vessel is just different, must meet the requirement of relevant pressurized vessel corresponding standard.
Described refrigeration agent claims refrigeration working medium again, is the working medium of refrigeration cycle, utilizes the phase transformation of refrigeration agent to transmit heat, heat absorption when both refrigeration agent is vaporized in vaporizer, heat release when condensing in condenser.Current energy has kind more than 80 as the material of cold-producing medium, and the most frequently used is ammonia, fluorine Lyons class, water and minority hydrocarbon etc., to the whole CFC classes of R11, R12, R113, R114, R115, R502 and the R22 etc. in fluorine Lyons and carbon tetrachloride (CCL
4), methyl chloroform (C

2F
4) be widely used in the automotive air-conditioning system at present.
Described lubricating oil, it is refrigerator oil, corresponding refrigeration agent composition difference, the corresponding difference of the composition of lubricating oil, the lubricating oil that is used for refrigeration compressor, in ISO 6743/3B classification,, refrigerator oil is divided into DRA, DRB, DRC and DRD kind according to the component characteristic of refrigerator oil, the service temperature of vaporizer and the type of used refrigeration agent.The refrigerator oil of the GB/T 16630 of China's promulgation in 1996 is divided into two big class: L-DRA, L-DRB/B.At present, adopt in the system of R134a cold-producing medium, lubricating oil can adopt polyether oil, and polyether oil is with oxirane (C
