Abstract
Disclosed is an intelligent ammonia leakage-proof refrigerating system for a fruit and vegetable refrigerator. An input end of a compressor (1) is connected with an input pipeline (2), an output end of the compressor (1) is connected with an output pipeline (11), the other end of each of the input pipeline (2) and the output pipeline (11) is respectively connected with an evaporator (3), ammonia detecting sensors (5 and 10) are fixedly mounted on the evaporator (3) and connected with a controller (8), and the controller (8) is respectively connected with an input end valve (4) and an output end valve (9) and connected with alarm devices in a controlled mode. The ammonia detecting sensors fixedly mounted on the evaporator are used for detecting leaked ammonia and capable of cutting off a power source of the compressor by the controller, so that the compressor stops running. Ammonia flow of the input pipeline and the output pipeline can be cut off by controlling the valves by the controller so that leakage of more ammonia is prevented.
Description
Technical field
The utility model relates to a kind of fruits and vegetables freezer refrigerating system, especially a kind of intelligent ammonia Anti-leakage type fruits and vegetables freezer refrigerating system.
Background technology
Evaporimeter is the heat exchanger that cold-producing medium evaporates therein.In refrigeration system, evaporimeter is to produce cool equipment, and refrigerant of low temperature is by evaporimeter, carries out heat exchange with the air in the external world, and the gasification heat absorption reaches the effect of refrigeration.The evaporimeter that freezer is used belongs to recuperative heat exchanger, the heat of evaporimeter is passed to cold-producing medium by tube wall formula wooden partition, and cold-producing medium gasifies at low temperatures, and heat is taken away from evaporimeter, heat exchange takes place with the medium (generally being air) that is cooled in evaporimeter again, thereby reaches the purpose of refrigeration.
Because liquefied ammonia is used as cold-producing medium and is widely used in the freezer refrigerating system, the leakproof of ammonia in the freezer evaporimeter is a topic that quilt is paid close attention to always, because the vapor pressure of liquefied ammonia is very big, if evaporimeter produces pore or crack, ammonia can be revealed rapidly, the fresh fruits and vegetables of storage are exposed in the ammonia environment for a long time in the freezer, very fast the rotting of meeting; And because freezer is the closed area, after ammonia was revealed, the freezer management personnel can not find at once, so some freezers are because the loss that the ammonia leakage causes is very big.
Summary of the invention
At the problems referred to above, the utility model proposes a kind of intelligent ammonia Anti-leakage type fruits and vegetables freezer refrigerating system, by compressor 1, input channel 2, output channel 11, evaporimeter 3, ammonia detecting sensor 5,10, controller 8, input valve 4, output valve 9, alarm lamp 6, alarm 7 and control circuit are formed.
Warning device comprises alarm lamp 6 and/or alarm 7.
The refrigeration system course of work is as follows: compressor is ammonia boil down to liquid ammonia, and ammonia is imported evaporimeter by input channel, and in evaporimeter, the evaporimeter heat is taken away in the liquid ammonia gasification, and the ammonia after the gasification enters compressor once more by output channel and is compressed.Heat exchange takes place in the evaporimeter and the medium (generally being air) that is cooled, thereby reaches the purpose of refrigeration.
When the ammonia detecting sensor on being fixed on the evaporimeter wooden partition detects the ammonia leakage, send signal and give controller, controller sends control signal, cut off compressor power, reduce evaporimeter rapidly, by two by-pass valve controls, cut off the flowing pressure of input channel and output channel ammonia, send alarm signal and remind administrative staff.
Native system has following advantage:
(1) on evaporimeter, fixedly mounts the ammonia detecting sensor, be used to detect the ammonia of leakage; (2) can cut off compressor power by controller, quit work; (3) by the controller by-pass valve control, can cut off input channel and output channel ammonia and flow, prevent to leak more ammonias.

Fig. 1 is the native system structural representation.
Specific embodiment
Intelligent ammonia Anti-leakage type fruits and vegetables freezer refrigerating of the present utility model system, by compressor 1, input channel 2, output channel 11, evaporimeter 3, ammonia detecting sensor 5,10, controller 8, input valve 4, output valve 9, alarm lamp 6, alarm 7 and control circuit are formed.
Warning device comprises alarm lamp 6 and/or alarm 7.
The refrigeration system course of work is as follows: compressor is ammonia boil down to liquid ammonia, and ammonia is imported evaporimeter by input channel, and in evaporimeter, the evaporimeter heat is taken away in the liquid ammonia gasification, and the ammonia after the gasification enters compressor once more by output channel and is compressed.Heat exchange takes place in the evaporimeter and the medium (generally being air) that is cooled, thereby reaches the purpose of refrigeration.
When the ammonia detecting sensor on being fixed on the evaporimeter wooden partition detects the ammonia leakage, send signal and give controller, controller sends control signal, cut off compressor power, reduce evaporimeter rapidly, by two by-pass valve controls, cut off the flowing pressure of input channel and output channel ammonia, send alarm signal and remind administrative staff.
