The specific embodiment
Illustrate that by Fig. 1 an embodiment of the present utility model is as follows.
With reference now to accompanying drawing 1, describe embodiment of the present utility model, in accompanying drawing, identical element numbers represents similar element.As mentioned above, as shown in Figure 1, the Combined drawer type chamber 50 of the variable volume independence air-blower control that the utility model provides, it comprises:
As shown in Figure 1, chamber mainly forms a large enclosure space by the test chamber door of testing casing 10, heat-insulation layer 10a and do not indicate in the drawings.
In the sealing large space, an air inlet baffle plate 13a and an air outlet baffle plate 13b are installed, a series of independent pilot regions 12 of common composition and a gas treatment passage 20a, return air channel 20b, an air-out passage 20c between air inlet baffle plate 13a, air outlet baffle plate 13b, each pilot region both sides air door 11 and upper and lower dismountable thermal-insulation baffle plate 21, cabinet wall, test chamber door, sealing thermal insulation plate.
Air inlet baffle plate 13a and air outlet baffle plate 13b are respectively arranged with air vent.
The bottom of gas treatment passage 20a is equipped with at least one group of humidification system 18, and humidification system 18 is positioned at air inlet one side of evaporimeter 17, when guaranteeing that gas needs humidification, be all pretreated through humidification system 18 before being driven into air-out passage 20c via fan 14.
On the casing of gas treatment passage 20a right side, at least one air-pressure balancing device 19 is installed, when the guard box internal gas pressure is high on the one hand, gas or steam can be via air-pressure balancing device 19 pressure releases to extraneous; Also the condensate water of backflow can be drained in humidification basin 18a on the other hand.
The top of air outlet baffle plate 13b is equipped with at least one group of temperature-humidity sensor.
During the chamber operation, controller drives air exhauster 15 runnings, air exhauster 15 drives fan 14 and rotates, fan 14 drives past return air passage 20b mono-lateral movement of the gas in pilot region 12, cause thus the malleation of fan 14 air outlet one sides and the negative pressure of air inlet one side, under the acting in conjunction of fan 14 air outlet one side malleations and air inlet one side negative pressure, pilot region gas flows into return air channel 20b through air door 11, enter gas treatment passage 20a via the air vent on air inlet baffle plate 13a again, and respectively through humidification system 18, after evaporimeter 17 or heater 16 pretreatment, air vent on air outlet baffle plate 13b enters air-out passage 20c, enter each pilot region 12 by air door 11 again, regulate the temperature field of each pilot region 12, moisture field, finally enter return air channel 20b, enter next gas treatment circulation.The gas treatment circulation is a continuous process.In process of the test, can close separately as required air door 11 and the corresponding air exhauster 15 of some or several pilot regions 12 both sides, open drawer, change test specimen, carry out the test of next batch sample.Temperature value, humidity value that temperature, humidity and the air outlet baffle plate 13b air outlet one side temperature-humidity sensor that controller is set according to chamber detects, humidification amount to humidifier is carried out the PID adjusting, and as required to refrigerating capacity or add heat and carry out the PID adjusting, thereby realize pilot region 12 temperature field, moisture field evenly, stable.
When intensification or high temperature and humidity test are done in chamber, if the case internal pressure is higher than external atmospheric pressure, by air-pressure balancing device 19 pressure releases, until the case external and internal pressure reaches poised state.
The Combined drawer type chamber 50 of the variable volume independence air-blower control that the utility model provides, because intensification, constant temperature, cooling, damp heat test have all been realized the automatic adjusting of controller, so, as long as will need the setting parameter of test good in use, chamber just can move by the parameter set, thereby realizes intelligentized control; Simultaneously, controller can be regulated the size that adds heat output, humidification output quantity, refrigeration output quantity automatically according to the size of chamber load, thereby realizes Energy Saving Control.
Above disclosed is only preferred embodiment of the present utility model, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim, still belong to the scope that the utility model is contained.
