Humidification Chambers

HumidiRcation Chambers The air-cooled heat exchanger is provided with humidification chambers in which the air is cooled to a close approach to the wet-bulb temperature before entering the finned-tube bundle of the heat exchanger. 

Approach temperature. The approach temperature, which is the difference between the process-fluid outlet temperature and the design dry-bulb air temperature, has a practical minimum of 8 to 14°C (15 to 25°F). When a lower process-fluid outlet teiTperature is required, an air-humidification chamber can be providea to reduce the inlet air temperature toward the wet-bulb temperature. A 5.6°C (10°F) approach is feasible. Since typical summer wet-bulb design temperatures in the United States are 8.3°C (15°F) lower than diy-bulb temperatures, the outlet process-fliiid temperature can be 3°C (5°F) below the dry-bulb temperature. 

Humid air with 02 is prepared for a gluconic acid fermentation. The humid air has been prepared by a special humidification chamber where 1.5 1/h of liquid water enters at the same... 

A typical biofilter setup consists of a blower, humidification chamber and a biofilter unit, and an additional pohshing unit (optional) such as granular activated carbon backup. The biofilter is composed of microbial communities supported on a packing surface material such as wet peat. 

The tapa was flattened by placing in a humidification chamber constructed of polyethylene over a work table. Moisture was introduced by misting within the chamber. The tapa was placed face down on blotters with weights at the edges to keep the piece under slight tension. Flattening took less than 2 hours. 

Funding for disposables, such as ventilator tubing, humidification chambers, suction catheters, etc. must be considered. It is helpful to list all ongoing disposable items to pass on to the general practitioner and community care team in order to ensure that everybody involved has adequate information as to who is responsible for these items, prior to discharge. This will prevent the patient from running out of basic equipment. 

C02 and l%Ar with 5-7.8% water subsequently added by bubbling the gas through a humidification chamber held at constant temperature. 

The honeycomb and seal samples were assembled and secured on the T-section carrier, as described earlier. Prior to the introduction of samples, furnaces were heated to the appropriate test temperature and the whole system left to equilibrate. Before entering the reaction tube, the test gas was first bubbled through a humidification chamber controlled at 40°C. Heated supply lines connected the humidifier to the reaction tube inlet in order to avoid water condensation. The correct flow rate was established and the specimen assembly slid into the reaction chamber normally, the samples took about 30 min. to reach the test temperature. In a similar manner, after the samples had been exposed for the required period, they were slowly removed from the furnace (again taking about 30 min.) and cooled to room temperature in laboratory air before desiccation and re-weighing. 

As soon as all of the spots are glistening, remove the slide from the humidification chamber and snap-dry it face-up on a 80"C heating block. This should only take a few seconds. A wave of evaporation flash across the surface should be seen. As soon as all the spots are dry, remove the microarray. Do not leave the array on the heating block for more than 6-8 seconds. Several arrays can be rehydrated simultaneously.
