The specific embodiment
As shown in Figure 1, the utility model is achieved like this,
It comprises evaporimeter 1, humiture transducer I 2, electric expansion valve 3, visor 4, device for drying and filtering 5, liquid reservoir 6, check valve 7, air-cooled condenser 8, PTC electric heater 9, humiture transducer II 10, blower fan 11, touch display screen 12, PLC controller 13, electric water adjustable valve 14, water-cooled condenser 15, electric three passes flow control valve 16, hot gas bypass solenoid valve 17, frequency-changeable compressor 18, hot-gas bypass electric expansion valve 19 and gas-liquid separator 20.
In use, in touch display screen 12, input required air-out dry-bulb temperature and relative humidity, in PLC controller 13, have dew-point temperature and calculate program, the digital quantity of dry-bulb temperature and relative humidity is transfused to calculation procedure, calculates setting dew-point temperature by calculation procedure.Simultaneously, when temperature-adjustable dehumidifier dehumidifying, air stream is through humiture transducer I 2, humiture transducer I 2 gathers dry-bulb temperature and rh value, and export dry-bulb temperature and the relative humidity signal electric current of 4~20mA, this electric current is sent into the collection of simulant signal unit of PLC controller 13 and is converted into corresponding digital quantity, calculates now airborne actual dew-point temperature too by the dew-point temperature calculating program in PLC controller 13.
When being greater than to set in dew-point temperature, actual dew-point temperature prescribes a time limit, PLC controller 13 provides signal to frequency-changeable compressor 18, tune up frequency-changeable compressor 18 capacities, when being less than to set under dew-point temperature, actual dew-point temperature prescribes a time limit, PLC controller 13 provides signal to frequency-changeable compressor 18, turns frequency-changeable compressor 18 capacities down.In actual dew-point temperature is being set dew-point temperature control range time, frequency-changeable compressor 18 capacities are constant.
When frequency-changeable compressor 18 loads are down to minimum load, actual dew-point temperature is still less than the lower limit of setting dew-point temperature, PLC controller 13 provides unblanking hot gas bypass solenoid valve 17, when opening after hot gas bypass solenoid valve 17, start to regulate the aperture of hot-gas bypass electric expansion valve 19, still be less than and set under dew-point temperature in limited time when recording dew-point temperature, continue to tune up the aperture of hot-gas bypass electric expansion valve 19, when recording dew-point temperature in dew-point temperature accuracy rating time, maintain this aperture constant, be greater than and set in dew-point temperature in limited time when recording dew-point temperature, turn the aperture of hot-gas bypass electric expansion valve 19 down, until after the aperture minimum of hot-gas bypass electric expansion valve 19, still be greater than to set in dew-point temperature and prescribe a time limit, now, close hot gas bypass solenoid valve 17, frequency-changeable compressor 18 is adjusted and carried.
The actual leaving air temp detecting by humiture transducer II 10 is sent to PLC controller 13, PLC controller 13 is set leaving air temp by actual leaving air temp and user and is compared, export the aperture (proportional integral valve) that a controlling value regulates electric stream adjustable valve 14, this controlling value is the standard analog signal of 4~20mA, when leaving air temp is higher than set temperature value, the aperture of electric stream adjustable valve 14 strengthens.Otherwise the aperture of electric stream adjustable valve 14 reduces, until leaving air temp and design temperature error are between ± 1 ℃.If the aperture of electric stream adjustable valve 14 is opened to maximum, return air temperature is still greater than 1 ℃ with design temperature difference, PLC controller 13 starts to regulate electric three passes flow control valve 16 by program, the cold medium flux that is communicated with air-cooled condenser 8 branch roads is turned down gradually, and the cold medium flux that is communicated with device for drying and filtering 5 branch roads strengthens gradually, leaving air temp is met and set requirement.If the aperture of electric stream adjustable valve 14 is opened to minimum, return air temperature is still less than 1 ℃ with design temperature difference, PLC controller 13 starts to regulate electric three passes flow control valve 16 by program, the cold medium flux that is communicated with air-cooled condenser 8 branch roads is tuned up gradually, and the cold medium flux that is communicated with device for drying and filtering 5 branch roads reduces gradually, leaving air temp is met and set requirement.
In the time that electric stream adjustable valve 14 apertures reduce to minimum and open to maximum towards the electric three passes flow valve 16 of air-cooled condenser 8 branch roads, and electric stream adjustable valve 14 apertures reduce to after minimum (10%), if the actual leaving air temp that humiture transducer II 10 detects is less than setting leaving air temp, open PTC electric heater 9; Set leaving air temp and electric stream adjustable valve 14 >=15% if the actual leaving air temp that humiture transducer II 10 detects is greater than, close PTC electric heater 9.
Utilize the variable frequency adjustment of frequency-changeable compressor 18 and the adjusting of electric expansion valve 3 to match, under the each operating mode of exact matching, the required moisture removal of reality, makes to meet the needed relative humidity requirement of user.Utilize electric stream adjustable valve 14 to regulate the start and stop of cooling water flow, electric three passes flow control valve 16 and PTC electric heater 9 to carry out cold (or heat) actual required under the each operating mode of exact matching, make to meet the required temperature requirement of user.Temperature control and humidity control are carried out simultaneously, until environment temperature and relative humidity all meet user's requirement.
