The air outlet place of said heat interchanger is provided with the dehumidifying curtain, below heat interchanger, is provided with water collector, and water collector is connected with the draining ball valve through metal tube, and the draining ball valve is connected through the outfall of metal tube with cabin body bottom;
Described intrinsic safety electric source is connected with the ventilation blower fan.
Be provided with high pressure gauge at described pressure reducer towards a side of stop valve, be provided with low-pressure meter towards a side of bus-bar at pressure reducer.
Described water collector be shaped as bowl-type, or be back taper.
The present invention compares with prior art has following beneficial effect.
One, through water collector is set, can effectively reduce the humidity of survival capsule below heat interchanger with collecting and discharge outside the survival capsule at the condensed water that heat-exchanger surface forms in the cold-producing medium temperature-fall period through outfall;
Through air outlet the dehumidifying curtain is set, can further dehumidifies, guarantee that the wind that blows in the survival capsule is dry air at heat interchanger.
Two, through towards a side of stop valve high pressure gauge being set at pressure reducer; Towards a side of bus-bar low-pressure meter is set at pressure reducer; Can in time detect, adjust pressure; Make high-pressure refrigerant through the decompression back low pressure entering bus-bar that confluxes,, effectively guaranteed the application life of each pipe fitting in each pipe fitting mesolow work.
Description of drawings
Below in conjunction with accompanying drawing the present invention is further described.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is that the A of Fig. 1 is to partial schematic diagram.
Among the figure, 1 cabin for survival, 2 is the refrigerant outlet pressure meter, and 3 is heat interchanger, and 4 are the ventilation blower fan; 5 is water collector, and 6 is outfall, and 7 are the draining ball valve, and 8 is air intake, and 9 is refrigerant cylinder; 10 is equipment compartment, and 11 is intrinsic safety electric source, and 12 is the high-pressure metal flexible pipe, and 13 is low-pressure meter, and 14 is high pressure gauge; 15 is bus-bar, and 16 is pressure reducer, and 17 is stop valve, and 18 is the cold-producing medium ball valve, and 19 are the ventilation fan switch; 20 is the refrigerant inlet pressure meter, and 21 is the cold-producing medium outlet opening, and 22 is air outlet, and 23 are the dehumidifying curtain.
