Description
Technical field
The present invention relates to a kind of environmental test equipment field, relate in particular to a kind of Combined drawer type chamber of variable volume independence air-blower control.
Background technology
Chamber usually designs, makes by certain volume, and after chamber was produced, volume also just can not change, and can cause two puzzlements for the client like this:
1, by the large volume chamber of existing large sample size buying.If follow-up small size, the multiple batches of sample of occurring, there will be small sample to take the situation of large volume chamber, cause the chamber utilization rate not high, the power consumption, and multiple batches of sample can not add in chamber midway, off-test before can only waiting for successively just can be tested, the quantity that perhaps increases chamber solves the test problem of multiple batches of sample, causes increasing considerably of test period prolongation or equipment purchase cost.
2, by the little volume chamber of existing small sample size buying.If the large-sized sample of follow-up appearance, can cause sample can not put into chamber, face and need to again purchase the situation of large volume chamber, cause leaving unused of existing equipment and increasing considerably of purchase cost.
Summary of the invention
But the purpose of this invention is to provide the Combined drawer type chamber of a kind of flexible combination volume size, with low cost, energy-conservation, the intelligent and variable volume independence air-blower control that is easy to apply.
to achieve these goals, technical scheme of the present invention is: a kind of Combined drawer type chamber of variable volume independence air-blower control is provided, described chamber is mainly by the test casing, heat-insulation layer, door and sealing thermal insulation baffle plate form the space of a sealing, described enclosure space bottom is provided with the gas treatment passage, gas treatment passage top is provided with the pilot region of some layerings by dismountable thermal-insulation baffle plate, the both sides of pilot region are equipped with independent air door and with two inwalls of casing, form respectively air-out passage and return air channel, pilot region air outlet one side is equipped with independently air exhauster and corresponding fan, the gas treatment passage is provided with the air outlet baffle plate over against the air-out passage place, the gas treatment passage is provided with the air inlet baffle plate over against the return air channel place, air outlet baffle plate and air inlet baffle plate are provided with air vent.
The chamber internal volume, by increasing or reduce the quantity of dismountable thermal-insulation baffle plate, can be realized the variation from little volume to large volume.
Described gas treatment passage is equipped with at least one group of heater.
Described gas treatment passage is equipped with at least one group of evaporimeter, and evaporimeter is positioned at air inlet one side of heater.

The specific embodiment
Illustrate that by Fig. 1 an embodiment of the invention are as follows.
With reference now to accompanying drawing 1, describe embodiments of the invention, in accompanying drawing, identical element numbers represents similar element.As mentioned above, as shown in Figure 1, the Combined drawer type chamber 50 of variable volume independence air-blower control provided by the invention, 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, the dismountable thermal-insulation baffle plate 21 of each pilot region both sides air door 11 and up and down, 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 was high on the one hand, gas or steam can be via air-pressure balancing device 19 pressure releases to extraneous; Also the condensate water that refluxes 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 one lateral movement of 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, enter finally 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, the humidification amount of humidifier is carried out PID regulates, and as required to refrigerating capacity or add heat and carry out PID and regulate, 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 variable volume independence air-blower control provided by the invention, all realized the automatic adjusting of controller due to intensification, constant temperature, cooling, damp heat test, so, as long as will need the setting parameter of testing good in use, chamber just can move by the parameter that sets, 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 the preferred embodiments of the present invention, certainly can not limit with this interest field of the present invention, and the equivalent variations of therefore according to the present patent application the scope of the claims, doing, still belong to the scope that the present invention is contained.
