In standard vapor-compression refrigeration cycles, vapor leaving the evaporator is slightly superheated (by $5^\circ\text{C}$ to $10^\circ\text{C}$) before entering the suction port of the compressor. This prevents liquid slugging, protects compressor valves, and ensures dry compression.

A spray cooling pond is an open water basin equipped with a network of elevated spray nozzles that atomize hot condenser water into the air. It has no complex internal packing, no mechanical fans, and minimal maintenance, making it the simplest of all industrial evaporative cooling methods.

Electrical energy consumption audit in dairy plants:

• $10\text{ to }20\%$ covers processing pumps, separators, and lighting.
• $20\text{ to }30\%$ is the electrical share in non-refrigerated dry manufacturing.
• $30\text{ to }40\%$ is below the average peak share for market milk plants.
• In a typical composite dairy processing plant, refrigeration (compressor motors, condenser fans, chilled water pumps, and cold store air handling units) constitutes the single largest electrical power consumer, accounting for approximately $40\text{ to }50\%$ of the total plant connected electrical load.

Nomenclature of halocarbon refrigerants (ASHRAE numbering system):

• Monochloro-monofluoromethane is $CH_2ClF$ (R-31).
• Freon 22 (R-22, Chlorodifluoromethane) has the chemical formula $CHClF_2$, representing monochloro-difluoro methane.
• Dichlorodifluoromethane ($CCl_2F_2$) is Freon 12 (R-12).
• Dichloromonofluoromethane ($CHCl_2F$) is Freon 21 (R-21).
