2. Compressed air dryer - Wikipedia

   en.wikipedia.org/wiki/Compressed_air_dryer

   Refrigerated dryers employ two heat exchangers, one for air-to-air and one for air-to-refrigeration. However, there is also a single TRISAB heat exchanger that combines both functions. The compressors used in this type of dryer are usually of the hermetic type and the most common gas used is R-134a and R-410a for smaller air dryers up to 100 cfm.

3. Fan (machine) - Wikipedia

   en.wikipedia.org/wiki/Fan_(machine)

   The cross-flow or tangential fan, sometimes known as a tubular fan, was patented in 1893 by Lionel Hightower, [17] [18] and is used extensively in heating, ventilation, and air conditioning (HVAC), especially in ductless split air conditioners. The fan is usually long relative to its diameter, so the flow remains approximately two-dimensional ...

4. Refrigeration - Wikipedia

   en.wikipedia.org/wiki/Refrigeration

   Other methods of refrigeration include the air cycle machine used in aircraft; the vortex tube used for spot cooling, when compressed air is available; and thermoacoustic refrigeration using sound waves in a pressurized gas to drive heat transfer and heat exchange; steam jet cooling popular in the early 1930s for air conditioning large ...

5. Heating, ventilation, and air conditioning - Wikipedia

   en.wikipedia.org/wiki/Heating,_ventilation,_and...

   Air handling unit, used for heating, cooling, and filtering the air. Air cleaning and filtration removes particles, contaminants, vapors and gases from the air. The filtered and cleaned air then is used in heating, ventilation, and air conditioning. Air cleaning and filtration should be taken in account when protecting our building environments ...

6. Rotary-screw compressor - Wikipedia

   en.wikipedia.org/wiki/Rotary-screw_compressor

   Refrigerated compressed air dryers with internal cold coalescing filters are rated to remove more oil and water than coalescing filters that are downstream of air dryers, because after the air is cooled and the moisture is removed, the cold air is used to pre-cool the hot entering air, which warms the exiting air. In other applications, this is ...

7. Refrigerator car - Wikipedia

   en.wikipedia.org/wiki/Refrigerator_car

   A mechanical refrigeration unit was installed at each end of the car, where sheet metal ducting forced cool air into the cargo compartments. The units, rated at 100 short tons (91 t; 89 long tons) capacity (more than twice that of the largest conventional refrigerator car of the day) were economical to load and unload, as no secondary packaging ...

8. Propane refrigeration - Wikipedia

   en.wikipedia.org/wiki/Propane_refrigeration

   Propane refrigeration is a type of compression refrigeration. Propane (R290) has been used successfully in industrial refrigeration for many years, and is emerging as an increasingly viable alternative for homes and businesses. Propane's operating pressures and temperatures are well suited for use in air conditioning equipment, but because of ...
