Adopt after technique scheme, the utility model compared with prior art has following beneficial effect:
Structure of the present utility model forms forced convertion in making in the controlled environment chamber, forced convertion and free convection are switched, no matter make to test starting stage indoor temperature and humidity under which kind of environmental condition and all can meet default steady state, thereby the primary condition that guarantees formal frost test is consistent, make frost experiment there is repeatability.
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: floor drain-9, drip tray-8, return air orifice plate-72, air-out orifice plate-71, culturing rack-6, body of wall-52, right side, body of wall-51, left side, phjytotron-5, humidifier-4, blower fan-3, air-return duct-22, air inlet duct-21, evaporimeter-1
The specific embodiment
As shown in Figure 1, the utility model is a kind of frost phjytotron, and its frost forms device and comprises blower fan 3, humidifier 4, is positioned at described artificial climate indoor evaporimeter 1 and circulation air path; Described humidifier 4 and described phjytotron 5 internal communication; Described circulation air path comprises air inlet duct 21 and air-return duct 22, described air inlet duct 21 and air-return duct 22 in the controlled environment chamber 5 interior culturing rack 6 both sides are oppositely arranged, there is air inlet air inlet duct 21 upper ends, there is return air inlet (air inlet and return air inlet are not shown in the drawings) air-return duct 22 upper ends, air inlet duct 21 and air-return duct 22 lower ends are all sealed, and described evaporimeter 1 is between described air inlet and return air inlet; Described blower fan 3 is positioned at air inlet duct 21, on the opposite side of air inlet duct 21 and air-return duct 22, is provided with corresponding wind hole (not shown).
The principle of this structure is: the cold air that evaporimeter produces is by blower fan inspiration air inlet duct 21, wind hole by air inlet duct 21 sides blows out again, after the cold wind blowing out and culturing rack 6 ambient air heat exchanges, enter in air-return duct 22, by the above-mentioned circulation again of return air inlet Returning evaporimeter.Repeatedly after circulation, the temperature of phjytotron just can reach predetermined initial temperature, humidifier 4 humidifications, and final artificial climate is indoor reaches predetermined initial humiture, and this is the process of a forced convertion; After reaching predetermined initial humiture, finish forced convertion, switch to free convection, realize frost.The switchable frost phjytotron of forced convertion and free convection, no matter make to test starting stage indoor temperature and humidity under which kind of environmental condition and all can meet default steady state, thereby the primary condition that guarantees formal frost test is consistent, make frost experiment there is repeatability.
With reference to Fig. 1, as a kind of preferred version, described air inlet duct 21 by the body of wall (left side body of wall 51) of described phjytotron and be positioned at this side wall body inner side on establish wind hole air-out orifice plate 71 form; Described air-return duct 22 by the body of wall (right side body of wall 52) of described phjytotron and be positioned at this side wall body inner side on establish wind hole return air orifice plate 72 form.The heat exchange scope of wind large (being substantially positioned at the space of the relative both sides of phjytotron body of wall) like this, thus can be fully for phjytotron be lowered the temperature, and by body of wall as the side that forms air channel, saved the use of sheet material, reduced cost.
Wind hole on described air-out orifice plate 71 and return air orifice plate 72 is for percent opening is little above, below the large distributed architecture of percent opening.Can guarantee that like this air, in the circulation of the bottom of air inlet duct 21 and air-return duct 22, prevents air flow shortcircuit, good cooling effect.Certainly, other branch's forms also can.
Refer again to Fig. 1, preferably below described evaporimeter 1, be provided with a drip tray 8.
Described drip tray 8 is obliquely installed, and below the culturing rack 6 of described phjytotron bottom, is provided with discharge outlet, and discharge outlet place fills a floor drain 9.Thereby guarantee the indoor environmental requirement of frost phjytotron.
Preferably, described humidifier 4 is ultrasonic humidifier.Ultrasonic humidifier can effectively improve the atomizing humidifying performance performance of equipment, and the energy consumption index that can reach micron number magnitude atomization (atomizing particle is evenly 5 microns of left and right) ，Shi unit's humidification amount is down to minimum.Humidification efficiency is high, adds wet strength large, and the droplet of generation is little and even, in the unit interval, can meet the requirements of rapidly relative humidity, and humidification speed is fast, saves water source; 2, the energy consumption index of unit humidification amount is low, and the energy consumption of ultrasonic humidifier only has 0.05kW/ (kg.h), is only equivalent to 1/15～1/10 of other humidification method, and day operation expense is low; Humidification is even.
Can also on described frost phjytotron, an observation window be set, be convenient at any time situation in observation ward.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
