The utility model will be further described below in conjunction with accompanying drawing.Fig. 1 is the utility model structural representation.Be to realize the principle of work of the present utility model and the course of work below:
When 1) winter, control was heated, double throw switch is pushed the winter use the E-F shelves, the E-F conducting, when the fog room room temperature was lower than design temperature 20 and spends, the resistance when thermistor resistance value ratio temperature controller circuit design temperature 20 is spent was big, the temperature controller circuit turn-on, relay J gets electric, and relay normally open point is closed, and A.C. contactor C1 coil is got, C1 normal opened contact closure, heating tube R gets the electrician and does the heating of the water in the water tank, and water temperature rises, and distributes water vapor the fog room temperature is risen, when rising to 20 when spending, when the thermistor resistance drops to the contrast resistance that equals to set 20 circuit when spending, temperature controller circuit stop conducting, relay J dead electricity, relay normally open contact disconnects, A.C. contactor C1 coil losing electricity, the C1 normal opened contact disconnects, the heating tube dead electricity, quit work, water tank is not heated.When room temperature is lower than design temperature 20 once more and spends, resistance when the thermistor resistance is spent than temperature controller circuit design temperature 20 again is big, the conducting once more of temperature controller circuit, relay J gets electronic work, and relay normally open point is closed, A.C. contactor C1 coil is got, C1 normal opened contact closure, heating tube R gets electric work, again the water in the water tank is heated, circuit repeats said process, finishes the next work period.After finishing a work period, the relay J dead electricity, relay normally open contact disconnects, when the normally closed contact of relay is closed, because of pushing the winter, double throw switch uses the E-F shelves, not conducting of E-D, so A.C. contactor C2 coil can't form the loop, the C2 normal opened contact is not closed, refrigeration air conditioner is not worked, because of after the heating a large amount of water vapor being arranged, relative humidity has reached 90%, so winter, heating need not spray.
When 2) summer, control was freezed, double throw switch is pushed the winter use the E-D shelves, the E-D conducting, resistance when thermistor resistance value ratio temperature controller circuit design temperature 20 is spent when the fog room room temperature is higher than design temperature 20 and spends is little, the not conducting of temperature controller circuit, relay J must not, contact is failure to actuate, the normally closed point of relay is closed, A.C. contactor C2 coil is got, C2 normal opened contact closure, when room temperature drops to 20 when spending, when the thermistor resistance rises to the contrast resistance that equals to set 20 circuit when spending, relay J gets electric adhesive, relay normally closed contact disconnects, make A.C. contactor C2 coil losing electricity, the C2 normally closed contact disconnects, the refrigeration air conditioner dead electricity, quit work, spend when room temperature is higher than design temperature 20 once more, the thermistor resistance is littler than temperature controller circuit contrast resistance value again, and the relay J dead electricity discharges, the relay normally closed contact closure, make A.C. contactor C2 coil once more electric, the C2 normal opened contact is closed again, refrigeration air conditioner gets the electric refrigeration of working once more, circuit repeats said process, finishes the next work period.After finishing a work period, relay J gets electric, and relay normally closed contact disconnects, when the normal opened contact of relay is closed, because of double throw switch pushes summer grade E-D shelves, not conducting of E-F, so A.C. contactor C1 coil can't form the loop, the C1 normal opened contact is not closed, and heating tube is not worked.Be attempted by refrigeration air-conditioner control circuit on because of solenoid valve this moment, and the control spray starts automatically automatically, makes fog room humidity reach standard state.Automatically control spray circuit limit switch is installed on the door of concrete test block maintenance chamber, and the mechanical contact of limit switch opens, close with the unlatching of door, close synchronously, and controls spray system, reaches to open the door that spray system is in closed condition when getting test block.
