Sap must first be collected and boiled down to obtain syrup. Maple syrup is made by boiling between 20 and 50 volumes of sap (depending on its concentration) over an open fire until 1 volume of syrup is obtained, usually at a temperature 4.1 °C (7.4 °F) over the boiling point of water.
A refrigerant needs to have: a boiling point that is somewhat below the target temperature (although boiling point can be adjusted by adjusting the pressure appropriately), a high heat of vaporization, a moderate density in liquid form, a relatively high density in gaseous form (which can also be adjusted by setting pressure appropriately), and ...

When used as a refrigerant, R-114 is classified as a medium pressure refrigerant. The U.S. Navy uses R-114 in its centrifugal chillers in preference to R-11 to avoid air and moisture leakage into the system. While the evaporator of an R-11 charged chiller runs at a vacuum during operation, R-114 yields approximately 0 psig operating pressure in ...
Different zeotropic mixtures have different temperature glides. For example, zeotropic mixture R152a/R245fa has a higher temperature glide than R21/R245fa. [7] A larger gap between the boiling points creates a larger temperature glide between the boiling curve and dew curve at a given mass fraction. [4]
2-Chloro-1,1,1-trifluoroethane, also known as 1,1,1-trifluoro-2-chloroethane or Freon 133a, is an alkyl halide belonging to the category of hydrochlorofluorocarbons, having chemical formula F 3 C-CH 2-Cl.
