The specific embodiment
See that Fig. 1, a kind of environmental simulation composite cabin are with low temperature control system; Composite cabin comprises Laboratory Module 1 and surge bunker 2; Low temperature control system includes refrigeration system and air treatment system in the cabin; Refrigeration system includes evaporimeter, condenser and the compressor that circulation connects in the cabin, and second cooling cycle system that first cycle refrigeration system that Laboratory Module is formed through first evaporimeter 3, first condenser 6 and one group of piston type compressed unit 9 of unit and first evaporimeter 4, second condenser 7 and one group of two-diameter piston formula compressor bank 10 are formed is to freezing in the cabin; The 3rd cooling cycle system that the buffering cabin is formed through the 3rd evaporimeter 5, the 3rd condenser 8 and two-diameter piston formula compressor bank 10 is to freezing in the cabin.
Air treatment system includes air cleaner 11, dehumidifier 12, orifice flowmeter 13, gas-gas displacer and the water-gas displacer 16 that connects successively; Gas-gas displacer comprises first gas-gas displacer 14 and second gas-gas displacer 15, and first gas-gas displacer 14 all is connected with orifice flowmeter 13, water-gas displacer 16 with second gas-gas displacer 15; Water-gas displacer 16 is connected through cooling tower 17, pond 18 and water pump 19 inlet with the three groups of condensers 6,7,8 that are interconnected successively.
See Fig. 2, Fig. 3; Sidewall, ceiling board and Ceiling are provided with finishing layer 20 along the cabin in Laboratory Module 1 and the surge bunker 2; Form air channel 21 between finishing layer and the cabin inwall; The top of Laboratory Module 1 and surge bunker 2 is respectively arranged with through muffler 22 (see figure 1)s and first gas-gas displacer 14, air inlet 23 that second gas-gas displacer 15 is communicated with, is provided with fresh air inlet 24 on the finishing layer at Laboratory Module 1 and surge bunker 2 tops, is respectively arranged with six and three centrifugal blowers 25 in the air channel at top; Be respectively arranged with eight and four air outlets 26 on the finishing layer of sidepiece, air outlet 26 all is communicated with the air channel 21 of corresponding cabin body bottom.
See Fig. 1, the operation principle of air treatment system is:
(1), the fresh air that will enter the cabin is through air cleaner 11, filters out airborne impurity, improves air purity;
(2), air gets into dehumidifier 12; In dehumidifier 12, dehumidify: carry out freeze drying earlier; Airborne most of moisture is separated, the air dew point temperature is reduced to about 4 ℃, air also is cooled to about 4 ℃ simultaneously; And then carry out the absorption type dehumidifying, the dew-point temperature of air is reduced to about-50 ℃;
(3), dried air (being new wind) is passed through the first gas-gas displacer 14 at Laboratory Module 1 top and the second gas-gas displacer 15 at surge bunker 2 tops; Get into Laboratory Module 1 and surge bunker 2 through air inlet 23, fresh air inlet 24 then; Mix with the Cryogenic air in the body of cabin gas one, the temperature of mixed gas one is lower than the temperature of new wind;
