"Dirt is probably the cheapest and simplest construction material out there, but it's not very strong compared to other choices. Luckily geotechnical engineers have developed a way to strengthen earthen materials with almost no additional effort - Mechanically Stabilized Earth (aka MSE or Reinforced Soil).

In this video we look at chiller types and refrigerant compressor cooling technology within HVAC commercial refrigeration and provide an overview guide on when and where each chiller type is used. This covers air cooled chillers and water cooled chillers, centrifugal compressors, turbocor compressors, screw compressors, scroll compressors, reciprocating compressors, absorption chillers. We look at both vapor compression and vapor absorption chillers. How chillers work and the basic working principle of each.
