A two-cycle cascade refrigeration process schematic diagram. A cascade refrigeration cycle is a multi-stage thermodynamic cycle. An example two-stage process is shown at right. (Bottom on mobile) The cascade cycle is often employed for devices such as ULT freezers. [1]
Vapor-compression refrigeration [6] For comparison, a simple stylized diagram of a heat pump's vapor-compression refrigeration cycle: 1) condenser, 2) expansion valve, 3) evaporator, 4) compressor (Note that this diagram is flipped vertically and horizontally compared to the previous one) [7] Temperature–entropy diagram of the vapor-compression cycle.
P 2 and V 2 the initial pressure and volume of the other cylinder and P 3 is the equilibrium pressure. An example could be a 100-litre (internal volume) cylinder (V 1) pressurised to 200 bar (P 1) filling a 10-litre (internal volume) cylinder (V 2) which was unpressurised (P 2 = 1 bar) (resulting in both cylinder equalising to approximately 180 ...
A representative pressure–volume diagram for a refrigeration cycle. Vapour-compression refrigeration or vapor-compression refrigeration system (VCRS), [1] in which the refrigerant undergoes phase changes, is one of the many refrigeration cycles and is the most widely used method for air conditioning of buildings and automobiles.
The compressor is specifically designed to run at different motor speeds to modulate cooling output. Variable speed operation requires an appropriate compressor for full speed operation and a special compressor lubrication system. Proper oil management is a critical requirement to ensure compressor lifetime.

From the IS4S Salute to Veterans Bowl on Dec. 14 to the College Football Playoff National Championship Game on Jan. 20, 82 teams will play in at least one postseason game.
Fig.5 Schematic diagram of a GM-cooler. V l and V h are buffer volumes of the compressor. The compression heat is removed by the cooling water of the compressor via a heat exchanger. The rotary valves alternatingly connect the cooler to the high- and the low-pressure sides of the compressor and runs synchronous with the displacer.
