Humidification method:
Be to guarantee the humidification amount quick and precisely in the humidification; Cut off of the influence of wet source simultaneously to air humidity in the case; Electrode humidifler air wetting process in to casing of the outer configuration of said casing is to regulate the voltage between the two poles of the earth in the electrode humidifler through temperature and humidity control system PID in the said casing, water vapor is sprayed into through humidification air jet pipe in flexible pipe, electric T-shaped valve and the casing rapidly and accurately handle in the wind, when humidity reaches required value in the case in the casing; The electrode humidifler electric three passes valve events simultaneously that quits work; Close and lead to a side in the casing, open by-pass valve, drain into unnecessary water vapor outdoor; Also cut off in the electrode humidifler being connected of humidification air jet pipe in the water source and case after this action is accomplished, can avoid of the influence of the interior water source of electrode humidifler air humidity in the casing.
Cooling method:
Said casing disposes handpiece Water Chilling Units outward; The chilled water temperature of setting is higher than the dewpoint temperature of set point of temperature air in the case; Only under this condition; In the time of could guaranteeing that cooling coil feeds the chilled water cooling during air cooling-down in to casing, can only be to air cooling-down in the casing and the phenomenon of dewfall dehumidifying can not appear in cooling coil, control system starting electrode formula humidifier is humidification again; Water-flowing amount is regulated through electric T-shaped valve PID by temperature and humidity control system in the casing, realizes the accurate control to air themperature in the casing.
Dehumidification mode:
Air themperature state stable in the casing is not caused influence of fluctuations for guaranteeing in the dehumidification process; Eliminate residual moisture on the dehumidifier evaporator simultaneously as far as possible and after dehumidifier stops to dehumidify, evaporate back the phenomenon that causes dehumidification rate to reduce in the casing again; A high-power dehumidifier of configuration and a miniwatt dehumidifier in the said casing; What adopt is the mode of freon refrigeration dehumidifying; Its evaporator and condenser are combined into one type back-to-back, when dehumidifier to casing in during air dewetting, the air in the case gets into from freon evaporator one side of low temperature; Airborne moisture is condensed on the evaporator and splashes into drip tray to drain into casing outer and remove moisture and the air that is cooled, lowers the temperature gets into the high temperature condenser of freon at once; Reheat room temperature, avoided the interior air themperature of casing to be lowered, keep the stable of the interior air themperature of casing because of dehumidifying.The freon evaporator of low temperature leaves remaining moisture and can't get rid of outside the casing; When dehumidifier quit work, the freon evaporator temperature can rise to the temperature inside the box gradually, and in this temperature-rise period; The water that has been condensed can't drain into outside the casing; Residual water branch is evaporated in the air in the casing very soon, has reduced the dehumidifying precision, has also consumed dehumidification rate.The moisture of the big more remnants of the surface area of freon evaporator is just many more, and is just big more to the influence of dehumidifying precision, and this part water to be dehumidifier all can't remove forever.Adopt a high-power and low power dehumidifier, segmentation dehumidifying gets final product head it off, can dehumidify fast and miniwatt dehumidifier capable of using is removed the residual moisture on the high-power dehumidifier.
The homogeneity of humiture in the case:
For each point aerial temperature and humidity in the guard box is put very even at one time; Handle wind uniform distribution air-line system and many circulating fan decisive role in the said casing; Space, return air passageway is divided into two relatively independent parts in the casing; One of which is the air-treatment section, and it two is the mixed ventilation section.Humidification air jet pipe in the said casing, high or low power dehumidifier, cooling coil, electric heating tube, processing centrifugal blower are installed in the air-treatment section and distribute air-line system.Suck through handling centrifugal blower that casing interior section air heats up during work, cooling, humidification, dehumidification treatments; Air after being processed is by handling blower fan through distributing even, the stable porch of delivering to each circulating fan of mixed ventilation section of air-line system; With other casings in send into each point in the casing after the air mixed; Because every circulating fan is accepted identical processing air, it is very good that all deliver to the humiture homogeneity of wind of each point.
Therefore the utility model has following beneficial effect with present compared with techniques:
Casing is by original boxly changing the formula of stepping into into, having solved the little problem of box medicine parking space; The utility model has improved aerial temperature and humidity homogeneity in the case; Existing humiture of stepping into bulk treatment recirculating air in the formula constant temperature and humidity experimental box employing return air passageway.Cooling coil, electric heating tube, electrical heating humidification water tank, dehumidifying coil pipe; All install in the return air folder, horizontal storied placement, length is long; Volume is excessive; And the humiture of each processing unit itself is also inhomogeneous, circles round the space and causes effectively fully mixing of air in the whole case when many circulation pressure fans suctions of evenly arranging can be divided into several relatively independent air-flows virtually when seeing off, has influenced the homogeneity of aerial temperature and humidity.The utility model circulating fan, return air flame plate air port and air-out air grille are identical substantially with prior art in the layout in return air passageway; But in the return air passageway, separated an airtight processing wind section; Heating, humidification, cooling, each functional part that dehumidifies are installed in this; A part of wind sucks in the processing section through after heating, humidification, cooling, the dehumidification treatments in casing; By handling centrifugal blower through delivering to the porch of each circulating fan of mixed ventilation section with handling wind uniform distribution air-line system stable and uniform; Again with other casings in air mixed send into space in the casing because many circulating fans are accepted the air after the identical processing, so the wind-warm syndrome humidity uniformity of seeing off is very good.
The utility model compared with prior art has the advantage that small investment, processing accuracy are high, energy consumption is low aspect the processing of air cooling, humidification, dehumidifying.
The type of cooling:
The direct vaporation-type cooling coil of freon that present technological employing can not PID be regulated is lowered the temperature; Because the direct evaporating temperature of freon is very low; The evaporator surface temperature is usually below 10 ℃, and is lower than air dew point temperature in the case, so the refrigeration system moisture that related handle is in the acceptability limit to air cooling-down the time has also been removed a part; Cause the qualified back of temperature and humidity is on the low side, can only start the humidification function raising humidity of going to keep the skin wet once more.Owing to can not regulate cooling by PID, because of evaporator temperature is too low, still has very big inertia to continue cooling after the shutdown and cause air themperature near defective district simultaneously, system starts heating function again, has increased energy consumption.
And the utility model adopts the chilled water cooling, confirms that at first the constant temperature and humidity of api request in the case is put pairing air dew point temperature value, the chilled water temperature of the handpiece Water Chilling Units of the outer configuration of said casing is set in to be lower than 1 ℃ ~ 2 ℃ of this dew point temperature value then.Control system only need can reduce the temperature in the range of control through the water yield that PID regulates electric T-shaped valve control chilled water fast and accurately when needing cooling; The chilled water that near desired temperature upper limit process, feeds can reduce gradually; The cooling coil bulk temperature rises near the temperature of air in the casing gradually; Electric T-shaped valve is closed when arriving desired temperature, this moment cooling coil with the temperature inside the box basically identical, this cooling method neither influences the influence that humidity has also been got rid of the inertia of lowering the temperature.
Humidification method:
What at present technology adopted is in a water tank, electric heating tube to be installed, and is heated to ejection steam to water through heating tube, is used for humidifying air, and this mode can not be regulated by PID.Control system is connected electric heating tube heating with full power water temperature when the needs humidification, and water temperature rises in the time of can spraying steam, and air humidity begins to rise; When being raised to required value, control system is closed electric heating tube, and this moment, water temperature was still very high; Inertia effect still has steam and is brought in the case; Cause humidity to exceed standard, control system can only start refrigerated dehumidification again, has increased energy consumption.
But and the electrode humidifler that the utility model adopts PID to regulate, the humidifier gas outlet links to each other through humidification air jet pipe in flexible pipe and a three-way solenoid valve and the casing, when needing humidification; Temperature and humidity control system starting electrode formula humidifier is opened T-valve simultaneously and is led to a side in the case; PID regulates the voltage between two electrodes in the electrode humidifler water tank, water vapor is sprayed into through humidification air jet pipe in flexible pipe, electric T-shaped valve and the casing rapidly and accurately handle in the wind, when humidity reaches required value in the case in the casing; The electrode humidifler electric three passes valve events simultaneously that quits work; Close and lead to a side in the casing, open bypass, drain into unnecessary water vapor outdoor; Being connected of humidification air jet pipe in the water source and case cut off in the electrode humidifler in this action, can avoid the influence of the interior water source of electrode humidifler to air humidity in the casing.
Dehumidification mode:
What technology adopted at present is with a freon evaporator condensation dehumidifying, and when control system order dehumidifying, refrigeration compressor starts; Low temperature freon gets into evaporator and begins cool-down dehumidification, and because of compensating the temperature of reduction, this moment, electric heating tube also will start to keep air themperature in an interval of acceptance air by cool-down dehumidification in the case; When humidity reaches setting value, stop refrigeration, but electric heating tube to be opened still and goes back up to the temperature inside the box until the evaporator bulk temperature and no longer descend; Defective of refrigerated dehumidification is the evaporator surface residual a lot of moisture of meeting forever, and these moisture can not form big water droplet, splash into drip tray; Outside the outflow casing, so when the evaporator surface temperature recovery, be evaporated to again in the interior air of case; Improved the humidity of air in the case; Reduce dehumidification rate (reducing by 50% dehumidification rate) on the one hand, reduced the control accuracy of humidity on the one hand again, increased energy consumption.
The utility model does not cause influence of fluctuations to air themperature state stable in the casing for guaranteeing in dehumidification process; Eliminate residual moisture on the dehumidifier evaporator simultaneously as far as possible and after dehumidifier stops to dehumidify, evaporate back the phenomenon that causes dehumidification rate to reduce in the casing again; A high-power dehumidifier of configuration and a miniwatt dehumidifier in the said casing, employing be the mode of freon refrigeration dehumidifying, its evaporator and condenser are combined into one type back-to-back; When dehumidifier to casing in during air dewetting; Air in the case gets into from freon evaporator one side of low temperature, and airborne moisture is condensed on the evaporator and splashes into drip tray and drains into outside the casing, and air also is cooled removing moisture simultaneously; The air of being lowered the temperature gets into the freon high temperature condenser that is installed in the same airtight casing at once; Reheat room temperature, avoided the interior air themperature of casing to be lowered, kept the stable of the interior air themperature of casing because of dehumidifying.When air humidity during near setting value, high-power dehumidifier is shut down, and the miniwatt dehumidifier continues operation; Be used to remove the residual moisture that reaches on the high-power dehumidifier evaporator on the drip tray; The miniwatt dehumidifier quits work when reaching setting value, and because of the miniwatt evaporator surface is long-pending little, residual moisture also seldom; Influence to air humidity in the case is just very limited, has basically no interference.
Stepping into the medicine of putting in the formula stability of drug products constant temperature and humidity experimental box self all will pack; So itself can not produce cold and hot humidity load; Get rid of the box sealing leakage problem theoretically; Personnel's turnover and new medicine are put into these disturbing factors, and air is after the primary cooling of process, intensification, humidification, dehumidification treatments in the case, and air humidity will remain on needs once more humidification or dehumidifying never on the fixing horizontal.And heating only needs to offset casing itself and the heat conducting refrigeration duty of outside air, and cooling only needs to offset the thermal load that casing itself and outside air heat conduction and recirculating air unit produce.
The processing mode of the intensification adopted of technology at present, cooling, humidification, dehumidifying is that to move each time be for remedying the new warm and humid imbalance that last time, action was produced basically, is the balance that in a kind of dynamic mode of energy consumption, reaches humiture.
For example: air themperature height in the case and humidity is qualified
Refrigeration cool-down → temperature is qualified; Open simultaneously heating offset refrigeration inertia → cause temperature to lower limit → humidification → humidity qualified → humidification inertia causes humidity qualified near the upper limit → dehumidifying → humidity; To open heating simultaneously and offset refrigeration duty → stop dehumidifying → evaporator temperature, the interior moisture of residual moisture and drip tray is evaporated in the air again → and cause humidity near the upper limit → dehumidifying ... Move in circles.
The processing mode of the intensification that the utility model adopted, cooling, humidification, dehumidifying has been eliminated the above-mentioned defective of prior art fully.
For example:
1, temperature the qualified startup cooling → air themperature of humidity is qualified near the upper limit → stop the cooling.
2, humidity the qualified startup dehumidifying → air themperature of temperature is qualified near the upper limit → stop high-power dehumidifier → stop miniwatt dehumidifier.
3, humidity the qualified startup humidification → air humidity of temperature is qualified near lower limit → stop humidification.
4, temperature the qualified startup heating → air themperature of humidity is qualified near lower limit → stop the heating.
Not only simply but also do not have the phase mutual interference, control accuracy was high for each function treatment, and energy consumption is very low.
More than technical scheme that the utility model embodiment is provided carried out detailed introduction; Used concrete example among this paper principle and the embodiment of the utility model embodiment are set forth, the explanation of above embodiment only is applicable to the principle that helps to understand the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, the part that on embodiment and range of application, all can change, in sum, this description should not be construed as the restriction to the utility model.
