Description
Technical field
The utility model relates to a kind of refrigeration system cleaning device, particularly a kind of chemically-cleaning device of freezing water system of central air conditioner pipeline.
Background technology
At present, the freezing water system of central air conditioner circulating line all will carry out chemistry or water and clean after installation before the driving, and its purpose is exactly the antirust oil that eliminating equipment and pipeline upper surface scribble, the welding slag in the installation, silt, dirt.While circulating frozen water system is after the water flushing, and the carbon steel pipes inner surface can produce floating rust, only has they are processed totally, makes the metal surface cleaning just can finish next step work.
The method of the flushing of tradition water or Chemical cleaning as shown in Figure 1, open water intaking valve 1, with the water injected system, open chilled water pump 2, make water circular flow in system take chilled water pump as power, then from water supplement port rinse water or Chemical cleaning medicament are injected the chilled water circulatory system by water injecting pump 11 by the water intaking valve 1 of opening from water supply tank 10.Clean after 12 hours, open blowoff valve 9, rinse water or Chemical cleaning medicament are drained.The hidden danger of the method maximum is the dirt in the refrigeration plant 8, impurity, greasy dirt, corrosion thing 16 is washed in the water by rinse water or Chemical cleaning medicament, under in the finned coil 15 of the slow air processor of flow velocity or fan coil 7, being detained, cause cooling effect not good, hot-spot, do not reach the expection cleaning performance, more seriously under deposit to finned coil corrosion phenomenon, a large amount of corrosion products 16 can stop up the finned coil 15 of air processor or fan coil 7, and Air-conditioning Engineering workmen will spend a large amount of manpowers, material resources, financial resources solve this problem.
The utility model content
The utility model provides a kind of chemically-cleaning device of freezing water system of central air conditioner pipeline, this system is by adopting secondary cleaning, with Impurity removal, solved the phenomenon that is trapped in air processor or the fan coil finned coil, improved system's running quality.
For achieving the above object, the technical solution adopted in the utility model provides a kind of chemically-cleaning device of freezing water system of central air conditioner pipeline, and this device includes the pipeline that is in turn connected to form with water intaking valve, chilled water pump, check-valves, the first control valve, the second control valve, air processor or fan coil, the 3rd control valve, refrigeration plant; Wherein: with pipeline that described the second control valve, air processor or fan coil, the 3rd control valve link to each other on a pipeline in parallel use the short circuit arm for cleaning, this cleaning is to connect the second stop valve by the first stop valve by pipeline to form with the short circuit arm.
The short circuit arm that effect utilization of the present utility model increases and two stop valves carry out the cleaning first time with air processor or fan coil disconnection, when containing a large amount of dirts, impurity, greasy dirt, corrosion thing in the cleaning fluid, cleaning fluid is drained from the blowoff valve of refrigeration plant, and secondary cleaning is carried out in water filling again.Disconnect the short circuit arm this moment, and cleaning fluid is flow through from air processor or fan coil, entering refrigeration plant, finish secondary cleaning work, at this moment a large amount of impurity in the system are removed, and can not be trapped in the finned coil of air processor or fan coil, have improved system's running quality.
Description of drawings
Fig. 1 is the freezing water system of central air conditioner tube cleaning arrangement structural representation of original technology.
Fig. 2 is freezing water system of central air conditioner tube cleaning arrangement structural representation of the present utility model.
Among the figure: 1 water intaking valve; 2 chilled water pumps; 3 check-valves; 4 first control valves; 5 second control valves; 6 the 3rd control valves; 7 air processors or fan coil; 8 refrigeration plants; 8 blowoff valves; 10 water supply tanks; 11 water injecting pumps; 12 first stop valves; 13 second stop valves; 14 short circuit arms; 15 finned coils; 16 dirts, impurity, greasy dirt, corrosion thing.
The specific embodiment
Reaching by reference to the accompanying drawings example describes the structure of the chemically-cleaning device of freezing water system of central air conditioner pipeline of the present utility model.
The basic thought of the chemically-cleaning device of freezing water system of central air conditioner pipeline of the present utility model is in existing closed cycle cooling water pipeline system, increase by one section short circuit arm and two stop valves, disconnect air processor first or fan coil cleans, to drain with the cleaning fluid of a large amount of floating rust, dirt, impurity, connect air processor again or fan coil cleans, original once cleaning is divided into twice carries out, effectively stop refrigeration plant and ducted corrosion thing to enter among air processor or the fan coil.
As shown in Figure 2, the chemically-cleaning device structure of freezing water system of central air conditioner pipeline of the present utility model is that this device includes the pipeline that is in turn connected to form with water intaking valve 1, chilled water pump 2, check-valves 3, the first control valve 4, the second control valve 5, air processor or fan coil 7, the 3rd control valve 6, refrigeration plant 8; Wherein: with pipeline that described the second control valve 5, air processor or fan coil 7, the 3rd control valve 6 link to each other on a pipeline in parallel for cleaning with short circuit arm 14, this cleaning is to connect the second stop valve 13 by the first stop valve 12 by pipeline to form with short circuit arm 14.
The chemically-cleaning device of freezing water system of central air conditioner pipeline of the present utility model is achieved in that
Air processor in existing closed cycle cooling water pipeline system or the two ends of fan coil 7, the loop that namely the second control valve 5, the 3rd control valve 6 front and back increase in parallel the first stop valve 12, the second stop valve 13 and cleaning is connected to form with short circuit arm 14.When carrying out Chemical cleaning for the first time, open water intaking valve 1, open simultaneously water injecting pump 11, from water supply tank 10, extract out rinse water or Chemical cleaning medicament in the injected system, close water intaking valve 1 after filling with water or medicament, ON cycle chilled water pump 2, make system's operation with pressure, rinse water or with the water of Chemical cleaning medicament by circulating frozen water pump 2 by check-valves 3, the first control valve 4, the first stop valve 12, the second stop valve 13 and cleaning flow into refrigeration plants 8 with short circuit arm 14, finish a circulation by pipeline, so circular flow corrosion to the system, dirt, after greasy dirt is cleaned, rest in the refrigeration plant 8, open the blowoff valve 9 of refrigeration plant 8, will be with corrosion, dirt, the sewer emptying of greasy dirt, air processor or fan coil 7 is unimpeded when guaranteeing to carry out secondary cleaning.
Then close the first stop valve 12, the second stop valve 13, make to clean with short circuit arm 14 to disconnect, open the second control valve 5, the 3rd control valve 6, make it to become the complete loops with air processor or fan coil 7.At this moment carry out secondary cleaning, open water intaking valve 1, open simultaneously water injecting pump 11, from water supply tank 10, extract out rinse water or Chemical cleaning medicament in the injected system, close water intaking valve 1 after filling with water or medicament, ON cycle chilled water pump 2, make system's operation with pressure, a large amount of foreign material in service, corrosion, dirt, greasy dirt 16 has been removed, in secondary cleaning, surface and oil contaminant in scavenging air processor or the fan coil can not cause the obstruction of the finned coil 15 of air processor or fan coil 7, cleans the blowoff valve 9 of opening refrigeration plant 8 after complete, secondary cleaning liquid is drained, finish cleaning of the present utility model, the method makes neither dam greasy dirt in the refrigeration plant of the finned coil 15 of air processor or fan coil 7, corrosion product 16 is again can cleaning performance very good.
