The purpose of this utility model is achieved in that
A kind of energy-saving constant-temperature constant-moisture case, it is a casing that has door, is provided with in described casing and places grate plate and the blower fan that test specimen is used, and is provided with a cooling tank at described casing top; Outside at casing is provided with temperature and humidity controller; Described box house is separated into operating room and hothouse by horizontal baffle; Side dividing plate with holes is housed in the both sides of described operating room, forms air delivery duct and air-return duct; Be provided with dividing plate with holes and drying agent pallet in the bottom of described hothouse; Be provided with the dividing plate of atresia in the both sides of described hothouse; Near the air outlet of blower fan well heater is set in the air delivery duct, the air inlet of blower fan is connected with hothouse.
Position near the case top in described operating room is provided with a small fan.
Described drying agent pallet can be a plurality of.
Described side dividing plate with holes and the described dividing plate with holes that is arranged on the hothouse bottom that is arranged on the operating room is to dash or the boring corrosion resistant plate; The described horizontal baffle that casing is separated into operating room and hothouse is a corrosion resistant plate.
Described hothouse can be established independently sealed door.
The utility model is simple in structure, make assembling easily, cheap, use in low, the long service life of operating cost, and have higher temperature, humidity control accuracy.The utility model can be applied in the dry shrinkage test of building materials and the test occasion of the strict control of other needs temperature and humidity widely.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model
Embodiment:
Be embodiment of the present utility model with accompanying drawing 1 below, the utility model be further detailed:
Must be placed in the air-conditioned laboratory during the utility model work, breadboard humidity is not limit, and breadboard temperature fluctuates up and down in setting value.Because the utility model does not have heat-insulation layer, but the casing of only making by sheet metal 1 that has door, so the heat of air will be realized heat interchange by casing sheet metal and casing extraneous air in the case.In casing 1 described in the utility model, be provided with and place grate plate 12 and the blower fan 10 that test specimen is used.Because it is essential by air in small fan 3 agitator tanks; make the interior air themperature of case even; air themperature always can be higher than environment temperature in the casing 1; and; also to consider of the influence of the initial temperature of test specimen to the temperature inside the box; therefore be provided with a cooling tank 2 at described casing 1 top; because cooling tank 2 is worn-out mouthful shape; water is evaporation constantly, takes away heat, and the water temperature in the tank 2 of therefore lowering the temperature usually can be than low 3 ℃～5 ℃ of environment temperature; and the position near the case top in described operating room 13 is provided with a small fan 3; small fan should face toward case top, i.e. the bottom blowing wind of tank is so that air cooling-down and make in the case air themperature even in the case.Be provided with temperature and humidity controller 14 in the outside of casing 1; Described casing 1 inside is separated into operating room 13 and hothouse 7 by horizontal baffle 6, and temperature, humidity are not disturbed mutually; Side dividing plate 4 with holes is housed in the both sides of described operating room 13, forms air delivery duct 11 and air-return duct 5; Be provided with bottom of which has holes dividing plate 8 and drying agent pallet 9 in the bottom of described hothouse 7, bottom of which has holes dividing plate 8 plays the effect that forms the bottom air-return duct, also plays the effect of drying agent pallet shelf simultaneously.Be provided with the dividing plate of atresia in the both sides of described hothouse 7, except the air inlet of blower fan; Described well heater 15 is arranged near the air outlet of blower fan 10 in the air delivery duct 11, and the air inlet of blower fan 10 is connected with hothouse 7; Well heater 15 in the air delivery duct 11 is subjected to the control of temperature and humidity controller 14, under the temperature inside the box situation in a single day on the low side automatically to case in air heat, the temperature inside the box is stabilized near the design temperature.Described drying agent pallet 9 can be provided with a plurality of, and drying agent pallet 9 bottoms are porose, guarantees the circulation of air.The side dividing plate 4 with holes of described operating room 13 is to dash or the boring corrosion resistant plate; The described dividing plate with holes 8 that is arranged on hothouse 7 bottoms can adopt sheet materials such as composited aluminum and plastic decking; Described dividing plate 6 should adopt corrosion resistant plate.In order to save drying agent, to prolong the cycle of changing drying agent, described hothouse 7 can be established independently sealed door.
Humidity Control work principle of the present utility model: during owing to the utility model work, the temperature inside the box and environment temperature are very approaching, so under the idle situation of dehumidification system, as long as place a water pond in the operating room, humidity just can reach more than 90% in the case.And the humidity that the building materials detection requires mostly is (43 ± 3) % or (65 ± 5) %, and the moisture content that gives out in the test specimen can make the humidity of air in the case always greater than the desired value of test generally speaking.So do not establish special-purpose damping device in the case, can place water pond in case of necessity increases humidity.When humidity was higher than setting value, 10 runnings of humidity measure and control instrument 14 control blower fans were blown into air delivery duct 11 with the dry air in the hothouse 7, enter in the operating room through side dividing plate 4 with holes again.Soft air in the operating room 13 then hole of the dividing plate with holes 8 by air-return duct 5 and bottom enters hothouse 7, and the humidity until the operating room reaches setting value.Drying agent pallet 9 can be provided with a plurality of, is placed on the base spacer, so that change drying agent in turn again.If adopt discolour silica gel as drying agent, use repeatedly after then the drying agent of Shi Xiaoing can be dried.
