Description
Technical field
The utility model belongs to technical field of refrigeration equipment, and specifically a kind of adjustable speed fan and refrigeration system are controlled the temperature inside the box simultaneouslySystem with relative humidity.
Background technology
Along with the fast development of China's economy, science and technology and medical and health care system, it is dark that new edition GSP applies in ChinaEnter, medical cold chain industry is more and more higher to the quality requirement of medical commodity, the temperature of the environment that GSP preserves medicine and relatively wetThe requirement of degree is also more and more stricter, and the storage box that can simultaneously control in the market temperature and relative humidity exists following two kinds of fraudsEnd: the one, because circulating fan in case is not to work always, the temperature homogeneity meeting in the time that circulating fan quits work in case in caseVariation, and then the quality of impact medicine preservation. The 2nd, for refrigerating box, in the time of compressor operating, on evaporimeter, be one constantlyThe process of frosting, can accelerate evaporimeter frosting when circulating fan quits work in case in addition, and long-play can make evaporimeter continuousFrosting and cause storage box normally not move.
Utility model content
The purpose of this utility model is to provide a kind of temperature and humidity control system reliably, by refrigeration system cool-down dehumidification, pass throughControlling magnetic valve opens and closes heat in case, make the temperature inside the box more even by adjustable speed fan humidification or dehumidifying simultaneously.
To achieve these goals, the technical solution adopted in the utility model is:
Be applied to a control system of controlling temperature and relative humidity in storage box, comprise refrigeration heating module, adjustable speed fan andMicrocomputer controlling module, described refrigeration heating module comprises compressor and magnetic valve, described microcomputer controlling module comprises that humidity passesSensor, temperature sensor and message handler; Described humidity sensor is connected with message handler, described temperature sensor and letterBreath processor is connected, and described compressor is connected with message handler, and described adjustable speed fan is connected with message handler, described electromagnetismValve is connected with message handler.
Preferably, described refrigeration heating module also comprises evaporimeter, condenser, case inner condenser, case external condenser and capillary,Refrigeration heating module comprises two pipeline refrigeration systems, a pipeline refrigeration system successively cascade evaporation device, compressor, condenser, magnetic valve,Case external condenser and capillary, another pipeline refrigeration system is cold in cascade evaporation device, compressor, condenser, magnetic valve, case successivelyCondenser and capillary. Described case inner condenser heats storage box. Described adjustable speed fan rotating speed can be according to relative humidity in caseRegulate.
In the time preserving the temperature inside the box or humidity higher than normal range (NR), feed back to message handler by Temperature Humidity Sensor, information placeReason device control compressor starts shooting to reduce the temperature inside the box and relative humidity, simultaneously according to high humidity minor adjustment adjustable speed fan in storage boxRotating speed, if in the time of compressor operating in case humidity higher than normal value, increase adjustable speed fan rotating speed, if in compressor shutdownTime case in humidity reduce adjustable speed fan rotating speed higher than normal value.
When humidity in storage box needs compressor start dehumidifying higher than normal value, if now the temperature inside the box is lower than normal value, informationProcessor by the temperature signal control magnetic valve that feeds back to open in case, heat to make up because of refrigeration produce unnecessaryCold, avoids the temperature inside the box lower than normal value.
When preserving the temperature inside the box lower than normal range (NR), message handler is by the temperature signal control compressor operating feeding back to,Magnetic valve is opened heating in storage box. The operation principle of heating is can discharge when the partial condensation heat of magnetic valve action post-condenserTo the interior refrigeration duty in order to balancing evaporator of case. Case external condenser is in parallel by magnetic valve with case inner condenser, the effect of magnetic valveBe that the action by magnetic valve makes cold-producing medium only be entered capillary or only be passed through outside case by case inner condenser in the time of compressor operatingCondenser enters capillary. When humidity in case is during lower than normal range (NR), whether compressor start-stop all increases adjustable speed fan rotating speed.
The beneficial effect that the utility model is obtained is:
Process and adjustable speed fan speed governing that process of refrigerastion, magnetic valve are opened heating are the processes of a constantly mutual co-ordination, noWith case in the corresponding different adjustable speed fan rotating speed of humidity, by continuous cooperating and then control the humiture in storage box repeatedly,Simultaneously due in case always the state in air blast cooling improved temperature homogeneity in storage box and suppressed the frosting of evaporimeterProcess, makes storage box operation steady in a long-term.
The utility model by refrigeration system cool-down dehumidification, by control magnetic valve open and close heating, pass through speed-regulating wind in caseMachine humidification or dehumidifying make the temperature inside the box more even simultaneously, prevent that humidity is too high or too low in case, simultaneously due to adjustable speed fan alwaysWork has suppressed the frosting trend of evaporimeter, and then ensures humiture in storage box.
Brief description of the drawings
Fig. 1 is applied to the structural representation of controlling the control system of temperature and relative humidity in storage box.
Fig. 2 is the structural representation of refrigeration heating module.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
In conjunction with Fig. 1, a kind of control system of controlling temperature and relative humidity in storage box that is applied to, comprise refrigeration heating module,Adjustable speed fan and microcomputer controlling module, described refrigeration heating module comprises evaporimeter, compressor, condenser, magnetic valve, caseInner condenser, case external condenser and capillary, described microcomputer controlling module comprises humidity sensor, temperature sensor and informationProcessor; Described humidity sensor is connected with message handler, and described temperature sensor is connected with message handler, described compressionMachine is connected with message handler, and described adjustable speed fan is connected with message handler, and described magnetic valve is connected with message handler.
In conjunction with Fig. 2, in refrigeration heating module, comprise two pipeline refrigeration systems, a pipeline refrigeration system is in series with evaporimeter, compression successivelyMachine, condenser, magnetic valve, case external condenser and capillary, another pipeline refrigeration system be in series with successively evaporimeter, compressor,Condenser, magnetic valve, case inner condenser and capillary.
In the time preserving the temperature inside the box or humidity higher than normal range (NR), feed back to message handler by Temperature Humidity Sensor, information placeReason device control compressor starts shooting to reduce the temperature inside the box and relative humidity, simultaneously according to high humidity minor adjustment adjustable speed fan in storage boxRotating speed, if in the time of compressor operating in case humidity higher than normal value, increase adjustable speed fan rotating speed, if in compressor shutdownTime case in humidity reduce adjustable speed fan rotating speed higher than normal value.
When humidity in storage box needs compressor start dehumidifying higher than normal value, if now the temperature inside the box is lower than normal value, informationProcessor by the temperature signal control magnetic valve that feeds back to open in case, heat to make up because of refrigeration produce unnecessaryCold, avoids the temperature inside the box lower than normal value.
