2.2.12 Pressure Garment Conditioning System2.2.12.1 Pressure Garment Conditioning Station

A. Pressure Suit Conditioning Design Requirements - Design Concept -The IB87189 PGA Drying Station Assembly is an air circulation pumpsystem that forces air from the OWS cabin through a flexible fiber-glass coated hose into the PGA red gas connector and then out the

PGA blue gas connector. As the cabin air flows through the airpump, the air temperature is _ncreased above ambient and feed_into the PGA assembly. As the air travels through the PGA, mois-ture is evaporated and picked up by the air, reducing the air tem-perature to Just e,few degrees above ambient. The air is thenexhausted into the OWS cabin. The output of the air pump is 18

ACFM (.505mS/rain), therefore resulting in an air volume of 10,800 ft.J(303m3) through the PGA durin_ a normal ten-hour drying cycle.After dynamic drying of the PGA, further drying is accompAishedby the addition of two desiccant containers approximately 80in.(203.2cI) in l_ngth. Each desiccant container holds 900 _. of

2.2.12-I


40/523

desiccant [at 270F (132C)] which is capable of absorbin_ a mlnim,Lm of50 gins.of moisture at a relative humidity of iO percent and an airtemperature of 75F (23.8C).i/ Design Requirements

a. The OWS shall provide a mean= of circulating unheatedcabin atmosphere through e pressure suit, using ablcwer vhich is similar to the WMS blower and desiccantbags for moisture removal. Each suit shall be driedsequentially utilizing total blower output for each

-" drying operation. Inflight drying of the desiccantbags shall be provided.

b. The P_A Drying Station Assembly must survive the loadsand environments induced during all preiaunch, launch,boost flight, and orbital operations of Skylab. Asummary of the design requirements is presented below.

Circulate OWS Cabin Air through PGA, Use power module identical to WMS. Maximum air temperature of 120F (_8.8C) at s,Jitinterface. Dry three suits in _8 hours (dyna_ically). Minimum air f_ow to PGA of i0.0 ACFM (.28m3/mln). AP of 3.5 in. (8.89 cm) water maximum rot PGA. Minimum moisture removed during dynamic drying to

be _00 gms. out of _Oo _ns. total.

Provide static 0esiccant cc._ainers (tvo per PGA)to remove a minimum of i00 gms of mo_,ture at i0percent RH at 75F (22.2eC).

Static desiccant containers to maintain air insuit below 55 pez .-nt afte; 50 hours.

Minimum number of drying cycles - 23.B. System Description

i/ Subsystem Configuration - The suit drying equipment con-sisting of a bi_er, hoses and desiccant bags is providedto remove moisture from inside the pressure suit_ after eachsuited operation. Pressure suits are dried at three (3)suit drying stations located in the OWS forward compartment.Drying is accomplished by installing a suit in the dryingstation which consists of the PGA pox'table foot restraints(attached to the forward compartment floor) and a hangerstrap which suspends the suit between the floor _d theva_er ring foot restraints. The b_wer unit forces dryingair _hrough a hose and into the suit. Moisture is rifledbythe air and collected by the desicce,:: bags. The desiccantbags are subsequently dried in the WMC waste processor,caamberz 5 and 6. Figure 2.2.12.1-1 provides an illustra-tion of this suit drying concept.The PGA Drying Station is composed of a s_orage ring Con-tainer Assembly with the following major components:

proposed for use in a semi-closed loop drying system. The: following basic procedure was followed:

The PGA drying system, including the PGA, waf_ installed inan environmental chamber that was controlled to the highes_air dewpoint expected for Skylab habitation area [60F (15.3oc)].The temperature was controlled at 83 .O F20 (28.3 to 29_hC) to testthe thermal characteristics of the Electronic Controller of the Dowermodule. The dry weight of the PGA and desiccant assemblieswas recorded Just prior to the drying test. 500 grms of

water were added to the liner of the PGA and PGA closedimmediately thereafter. During the drying operation, thecontinuous decrease in PGA weight was to be ,ecorded butdata was lost due to the electronic setup. In one case onlywas the continuous decrease in PGA weight obtained. A sum-mary of the results of the six ten-hour drying tests isnoted in Figure 2.2.12.1-2.

5/ Problems and Corrective Actionsa. Problem - During the initial function air flow test, the power

module failed to exhaust a minimum of 5 ACFM (.li_OmJ/min)to the two PGA. Flow rate as measured was below call-bration of the flowmeter.

@ Solution - A rubber duct was added to the powermodule exhaust port and routed to the non-

propulsive vent. At the non-propulslve vent arubber seal was added to prevent air leakage and

P.2.1?-lO


49/523

,_.?.l;_-Ll


50/523

to channel the air into the manifold assembly.After this duct addition, the air flow versus APexceeded the design requirement of 5 ACFM (.lh0mS/min)to each PGA.

b. Problem - During the initial ten-hour functional test wherethe test chamber was controlled at 83 +2o (28.3 to 29.4C), th__O Fpower module electronic controller overheated .

.130 .33 Solution - A small orifice 1.13h in. dia.( ] was cut in335 cm;

the rubber duct previously added and air flow channeledacross the electronic module. This orifice provided 1.3 ACFM

(.036hm3/min) to the electronic module which reduced the tem-perature approximately 12F (-II.IC). To reduce the tem-perature further, another orifice was cut to increasethe air flow but during the test vezification run, thenew orifice did not reduce the temperature any appre-ciable amount. Therefore, all remaining tests (lifecycle) was run with one orifice only. The resulting

i temperature was acceptable to the manufacturer of thepower module.

c. Problem - During a functional drying test performed at MSC/NASA

where approximately 6.85 ACMF (.191m3/min.), [70% 0^/30% N_, and _OF(32.2C) and 60dp (15.550C)], was channeled through the PGA, &pproxl-

mately 75 grams of moisture (water) remained in the suit after 5-1/2hours of drying using an open loop system. The excessivemoisture (75 gins) was considered by MSC/NASA to be not

2.2.12-12


51/523

adequate for control of Fungal contamination resultingin desradation of PGA materials. Solution - Change concept from drying two PCA's at

time to one PGA at a time. Also_ after drying PGAwith air flow power module, place in the PGA asufficient amount of desiccant to absorb the remainingmoisture. A 6-1/2 ft (1.97m) length of ZitexDesiccant Assembly was added to the drying tech-nique. Test data that uses a PGA simulator (i/i0volume of actual PGA) and a desiccant bag m,_nu-factured out of Zitex material and Silica Gel wastested with satisfactory results. Two vacuumdrying tests using the vet desiccant bags resultedin the desiccant being dried completely after tenhours.

6/ Subsystem Conclusionsa. Stuumary of Capabilities Versus Requirements - Based on

the test results and the power module performance afterlife cycles the air flow rate and moisture removal hasbeen demonstrated. Removal of moisture remaining inthe PGA after dynamic drying was also demonstrated.It is concluded from test results that the PGA DryingStation will meet all design requirements for use onthe OWS.

a little, showing that there is not a vacuum. Now whatoccurs in this case is that you don't get a good dryingand you also leak atmosphere out. Not fast and not criti-cally, but enough so that it is noticeable. The ones thatare on the top of these desiccants are the ones that thenext crew should use. And if _hey put them in there, to besure that they check, to make sure that the door has a goodvacuum seal before they wander off, and set the timer andleave. You put it in, close the door and as you move the

lever, listen for a little vacuum sound. Then try the doorand see if it csa_be easily pulled out. If it cannot, you'reokay. So set the timer and go on. If it flunks this, thesound, or the fact that the door will open without a lot ofeffort, then you probably haven't got a good vacuum in thereand you need to go back and do it again. We've got a coupleof desiccant lengths that won't fit and they're marked withred tape. It's probable that there are others around there,but hopefully toe ones that you pick out right at the topof the sacks will be the ones we used and will be acceptable.

E. Conclusions and Recommendations

Suit Drying - Suit drying was accomplished satisfactorily. The

initial suit drying was accomplished for the SAS EVA. Two suits

were dried and 2 desiccants per suit were dried in the processor

chambers No. 5 and 6. The six spare desiccants were removed to

a locker and stowed without drying. The suits were always dried

adequately and there was no evidence of bacterial growth or odor.

The noise level during operation of the bicwer was unobJectionaOle.

Hose lengths were acceptable. There were no other changes in

procedures oz hardware recommended by the flight crew.

The suit drier power module was too hot to touch. This unit was

operated with the ring compartment door closed per procedure.

Crews will be instructed to leave the door open for additional

cooling. There is no present explanation for %he "hot" blower.It was recommended that if the condition recurs_ the crew would

measure the temperature using the digital thermometer.

F. Development History - During the latter period of the waste

management hardware deliveries, the requirement for drying the

pressure garment assemblies (PGA) became apparent and an additional

power module was added to the Workshop to be used for suit drying.

In addition, desiccants used to keep the suit dry were dried in

one of the wast
