A dispenser with compressor cooling is a device that is used to dispense cold water or other beverages. It typically consists of a compressor-based cooling system that chills the water or beverage to a desired temperature and a dispenser mechanism that dispenses the liquid.

The compressor cooling system works by compressing a refrigerant gas, which causes it to become hot. The hot gas then flows through a series of coils, where it releases its heat and condenses into a liquid. The liquid then flows through an expansion valve, which causes it to evaporate and become cold. This cold gas then flows through a second set of coils, where it absorbs heat from the water or beverage, cooling it to the desired temperature.

Dispensers with compressor cooling are often used in homes, offices, and public spaces such as gyms or schools. They can be connected directly to a water supply, or they may have a reservoir that needs to be refilled periodically. They are generally more expensive than other types of dispensers, such as those with thermoelectric cooling, but they are also more efficient and can provide colder water more quickly.
