Refrigerated rail cars‚ also known as reefers‚ are insulated boxcars that keep their cargo at a regulated temperature‚ usually around 2 or 3 degrees Celsius. The first reefers relied on ice to cool their load‚ but now diesel-powered refrigeration units have replaced the ice as a more effective way to cool the load. The refrigerated rail car was patented by J.B. Sutherland in Detroit‚ Michigan in 1867. He designed an insulated car with ice at either end. This allowed air to come in from the top‚ pass

Ventilation rates are often expressed as a volume rate per person (L/s per person). The conversion between air changes per hour and ventilation rate per person. The equation to calculate this is L/s = (ACH*D*h)/60 Where L/s is the ventilation rate per person (L/s per person)‚ ACH is the air changes per hour‚ D is the Occupant density (occupants per square foot‚ occupants per square meter) h is the ceiling height (ft. meters) As per Building Regulations 2010‚ Approved Document F‚ every kitchen

Air Conditioner Report The use of concrete blocks in buildings construction decreased natural ventilations in the structures. The situation was worsened by house designs in urban areas where there were small spaces left for air waves. This lack of ventilation and variations n weather patterns necessitated a gadget that would keep rooms at suitable temperatures for human comfort. The air conditioner has a mechanism that absorbs humidity from the air to create a cooling effect inside buildings when
