What are some types of cooling systems?
Mechanical compression, Absorption, Evaporative, thermoelectric.

Evaporative coolers can drop the air temperature by X if the entering air is dry.
20 degrees Fahrenheit

Evaporative cooling
What is the Peltier Effect?
The principle that makes thermoelectric refrigeration work. When current flows through a thermocouple, one end heats up and the other cools down.
Compression refrigeration cycle operating principles are?
-Heat travels from hot to cold.
-Liquids absorb large amounts of heat when they boil off to a gas.
-Gases release large amounts of heat when they condense to a liquid.
-When something is boiling or condensing, its temperature remains constant.
-The temperature at which a liquid boils is controlled by its pressure.
What is a metering device?
Controls the flow of refrigerant into the evaporator of a refrigeration system.
