devices like capillary tubes and thermostatic expansion valves. The electronic expansion devices are usually provided with an automatic controller that is responsible for determining the valve opening that keeps the superheat at the outlet of the evaporator within the desired limits. Most of these controllers permit only the adjustment of the desired superheat‚ the proportional‚ the integral and the derivative gains. After being adjusted for one operating point‚ these parameters do not suffer any

fed into the sugar house. The sap is poured into an evaporator‚ the maple sugar evaporators are specifically designed to boil off hundreds of gallons of water quickly so the sap is concentrated into maple syrup. This is called boiling down‚ the evaporator works by heating the sap so it is almost boiling‚ as the water boils off and the sugar becomes more concentrated the sap moves to the pan. The pan is located in the rear part of the evaporator. In the pan the sap actually becomes syrup‚ once it’s

The Refrigeration Process Refrigeration has probably been around longer than you think. In 1823‚ Michael Faraday discovered that certain gases under constant pressure will condense when they cool. In 1875‚ Raoul Picet used sulfur dioxide as a refrigerant and in 1931 Refrigerant R-12 was developed by Thomas Midgley and C. F. Kettering. The Kelvinator refrigeration unit‚ ice cream units‚ and Semi-hermetic compressors were introduced at the beginning of the 20th century. In this
