Abstract
The present invention discloses a measurement method for the content of water and oil in recycled refrigerant, aiming to provide a measurement method which can effectively judge the content of water and oil in recycled refrigerant and is beneficial to solve the problems in actual operation. The present invention comprises the following steps that: the weight of a drying filter is measured and recorded as G1; the drying filter is filled with recycled refrigerant and then has the weight measured and recorded as G2; the refrigerant is kept liquid and is fully absorbed by the drying filter, then the refrigerant liquid in the filter is exhausted, and the drying filter is measured and recorded as G3; the emptied filter is put into a drying box, and after the filter is fully dried, the filter is measured and recorded as G4; G2 minus G1 is the weight of the refrigerant poured into the drying filer; G3 minus G1 is the weight of water and oil in the recycled refrigerant; G3 minus G4 is the weight of the water in the recycled refrigerant; G4 minus G1 is the weight of the oil in the recycled refrigerant. The method of the present invention is simple, economical and reliable.
Description
Technical field
The present invention relates to a kind of measuring method, more particularly relate to a kind of measuring method that reclaims moisture and oleaginousness in the refrigeration of calculating.
Background technology
Be environmental protection and others requirement, the cold-producing medium that reclaims in the various refrigeration systems is necessary.In service in refrigeration system owing to sealing and reason such as lubricated, must contain moisture and lubricating oil in the cold-producing medium of recovery.If the cold-producing medium that is reclaimed is carried out recycling, or utilize the cold-producing medium that reclaims to judge the operation of refrigeration system, just must measure moisture and oily water cut in the cold-producing medium that reclaims.But moisture in the cold-producing medium of how determining to reclaim and oleaginousness be the feasible method of neither one simple economy also.
Summary of the invention
The present invention is in order to overcome weak point of the prior art, and moisture and oleaginousness in a kind of cold-producing medium that can judge recovery effectively are provided, and helps solving the measuring method of moisture and oil content in the cold-producing medium of recovery of the problem in the real operation.
The present invention is achieved through the following technical solutions:
The measuring method of moisture and oil content is characterized in that in a kind of cold-producing medium of recovery, comprises the steps:
(1) weight of weighing device for drying and filtering and be recorded as G1;
(2) in device for drying and filtering, be full of the cold-producing medium of recovery, weigh and be recorded as G2;
(3) make cold-producing medium keep liquid, after the drying filtrator fully absorbed, the refrigerant liquid in the emptying filtrator was weighed and is recorded as G3;
(4) filtrator after the emptying is put into drying box, after the abundant drying of device to be filtered, weigh and be recorded as G4;
(5) the weight G1 that deducts in the step 1 with the weight G2 in the step 2 is the refrigerant amount that is charged in the device for drying and filtering; The weight G1 that deducts in the step 1 with the weight G3 in the step 3 is moisture and an oily weight in the cold-producing medium that reclaims; The weight G4 that deducts in the step 4 with the weight G3 in the step 3 is the weight of moisture in the cold-producing medium that reclaims; The weight G1 that deducts in the step 1 with the weight G4 in the step 4 is the weight of oil in the cold-producing medium that reclaims.
Environment temperature in the wherein said step 3 generally is higher than the temperature of solidification of cold-producing medium, is lower than the freezing temperature of water.The temperature of drying box in the step 4 generally is higher than normal temperature, is lower than the temperature of the fierce volatilization of oil.
The present invention has following technique effect:
Use measuring method of the present invention can judge moisture and oleaginousness in the cold-producing medium of recovery effectively, help the cold-producing medium that reclaims is carried out recycling, and moisture and the oily operation conditions of judging refrigeration system by being contained in the cold-producing medium that reclaims, help solving the problem in the real operation.And method is simple, economical, reliable.
Description of drawings
Fig. 1 is the process flow diagram of the measuring method of moisture and oil content in the cold-producing medium of the present invention's recovery.
Embodiment
Below in conjunction with accompanying drawing, and to reclaim cold-producing medium with R22 be that specific embodiment is to the detailed description of the invention.
Fig. 1 is the process flow diagram of the measuring method of moisture and oil content in the cold-producing medium of the present invention's recovery, and the measuring method of moisture and oil content comprises the steps: in the cold-producing medium that the present invention reclaims
(1) at first select a kind of with recovery cold-producing medium to be measured the small-sized device for drying and filtering of corresponding use, present embodiment has been selected the special-purpose small-sized device for drying and filtering of R22z, and retaining valve is housed at the filtrator two ends, weighing up at this moment with the high precision Libra, the weight record of device for drying and filtering is G1.
(2) open the retaining valve at two ends, charge the cold-producing medium of recovery,, at this moment shut the retaining valve at filtrator two ends, weigh and be recorded as G2 with the high precision Libra up to cold-producing medium from the retaining valve trickle of the other end from device for drying and filtering one end.
(3) put in-10 ℃ of environment being full of the filtrator that reclaims cold-producing medium, after 48 hours, take out filtrator, make device for drying and filtering fully absorb the cold-producing medium of recovery after, open retaining valve, refrigerant liquid in the emptying filtrator is weighed and is recorded as G3 with the high precision Libra.
(4) filtrator of opening the two ends retaining valve is put in the drying box, temperature is 35 ℃, takes out filtrator after 30 minutes, weighs and is recorded as G4 with the high precision Libra.
Utilize said method claim weight calculate: the weight G3 in the step 3 deduct weight G4 in the step 4 for containing the weight of moisture in the cold-producing medium, the weight G1 that weight G4 in the step 4 deducts in the step 1 is the weight that contains oil in the cold-producing medium, weight G2 in the step 2 deducts the weight that weight G1 in the step 1 is the recovery cold-producing medium that charges, and the weight G3 in the step 3 deducts weight G1 in the step 1 for reclaiming the moisture that contains in the cold-producing medium and the total amount of oil.
