Refrigeration Cycle: Direct Expansion Refrigeration System

June 30th, 2026

A direct expansion, or DX, refrigeration system is the simplest of the refrigeration cycles. In a DX system high pressure liquid is supplied through an expansion device, directly into the evaporator, hence the name “direct expansion”. As the refrigerant absorbs heat in the evaporator, it boils as it transitions from a liquid to a vapor. […]

Refrigeration Cycle: Building a Vapor Compression System

June 16th, 2026

Imagine there was a container with an infinite amount of saturated refrigerant, and this refrigerant was both non-toxic and environmentally friendly. Connecting this container to a compressor inlet would allow pressure control inside the container to a desired setpoint. Since the refrigerant is saturated, adjusting the pressure also changes the refrigerant’s boiling temperature. This allows […]

Refrigeration Cycle: Changing the Boiling Point

June 2nd, 2026

Opening a thermodynamics textbook, it is stated that the purpose of a refrigeration system is to maintain a cold region at a temperature below the temperature of its surroundings. This can be accomplished by employing a vapor compression refrigeration system. To understand how a vapor compression refrigeration system works, let’s start with a familiar substance…“water”. […]
