The specific embodiment
Referring to Fig. 1: the utility model comprises fog room 5 and humiture automatic control device 1 two large divisions thereof.Be provided with support 6 in the fog room 5, be used to place test specimen 7.Humiture automatic control device 1 has two kinds of versions.
Example one
Humiture automatic control device 1 comprises damp and hot aqueous medium generator 4 (employing steam generator), refrigeration compressor 3 and automatic controller 2; The shower 11 of steam generator 4 and the refrigerator pipes 10 of refrigeration compressor are arranged in the fog room 5, on the steam shower 11 shower nozzle are arranged.Steam generator 4 is used for humidification, heats, and refrigeration compressor 3 is used for cooling.
Referring to accompanying drawing 2, Fig. 3: steam generator 4 is made up of water tank 17 and electric heater wherein, has water inlet 12, steam outlet 15, heating terminal box 16 on the water tank 17.Another characteristics of the present utility model are to adopt finned electric heater, and heating 13 is arranged in the fin 14.Because fin 14 heat transfer areas are big, thermal capacitance is little, and it is fast to conduct heat, and steam generation is rapid during energising; Cooled off rapidly during power failure, stop immediately steaming.This steam generator 4 is used for automatic regulating system, and lag time is short, and response speed is fast, just can guarantee degree of regulation.
Automatic controller 2 adopts WSK type electronic digital to show temperature, humidity controller, this instrument is commercially available approved product, have supporting temperature sensor 8, humidity sensor 9, measured signal digital display screen and correspondent control circuits, satisfy needs of the present utility model fully.The type selecting parameter of automatic controller 2:
Temperature measurement range 0-60 ℃; Moisture measurement scope 0-98%.
Control accuracy temperature ± 2 ℃; Humidity ± 5%RH.
Example two
Referring to Fig. 4: with example one difference be, damp and hot aqueous medium generator 4 adopts hot water generators, and it comprises water tank 20 and electric heater 19 wherein, and water tank 20 is provided with water inlet 18, hot water rear pump 21, terminal box 22.Water temperature in the water tank 20 is controlled to be steady state value by automaton, and this steady state value is answered>20 ℃, promptly is higher than 20 ℃ of curing temperature setting values.Hot water is by pump 21 outputs, and the atomizer on shower 11 forms water smoke, supplies wet, heat supply to fog room 5.All the other are identical with example one.
When the utility model uses, should set controlled parameter according to the maintenance standard earlier, set value and be: 20 ℃ of temperature; Relative humidity>95%RH.Its course of work is as follows:
In the winter time, temperature is low, the air drying, temperature is lower than 20 ℃ in fog room 5, or relative humidity is when being lower than 95%RH, damp and hot aqueous medium generator 4 starts, input wet-hot steam/water smoke in fog room 5 is in this process, when humidity reaches setting value 95%RH and temperature and still is lower than 20 ℃ of definite values, damp and hot aqueous medium generator 4 continues for wet-hot steam/water smoke, when temperature also reached setting value, damp and hot aqueous medium generator 4 stopped, at this moment, humidity will be greater than 95%RH, but this standard permission just, requires.Otherwise, when temperature reaches setting value and humidity when still being lower than definite value, damp and hot aqueous medium generator 4 continues also to reach setting value for wet-hot steam/water smoke up to humidity, obviously, this will cause temperature to be higher than setting value, rise so reach the moment of setting value when temperature, refrigeration compressor 3 also starts, cooling in fog room 5, when temperature, humidity all reached setting value, damp and hot aqueous medium generator 4, refrigeration compressor 3 all stopped.
In summer, the temperature height, there was dampness in the air, and humidity satisfies setting value>95%RH in fog room 5, and temperature is when being higher than 20 ℃, and refrigeration compressor 3 starts, and cooling in fog room 5 drops to when setting value to temperature, and refrigeration compressor 3 stops.When humidity in the fog room 5 is lower than setting value and temperature is higher than setting value 20 ℃ the time, damp and hot aqueous medium generator 4, refrigeration compressor 3 start simultaneously, confession wet-hot steam/water smoke, cooling in fog room 5.In this process, when moisturt register reached setting value, damp and hot aqueous medium generator 4 stopped, and refrigeration compressor 3 works on, and reduced to setting value up to temperature and just stopped.When temperature drops to setting value and humidity still is lower than when setting value, damp and hot aqueous medium generator 4, refrigeration compressor 3 can not stop, and when temperature, humidity all reached setting value, damp and hot aqueous medium generator 4, refrigeration compressor 3 stopped simultaneously.
