Design and energy consumption

unlike a full-sized refrigerators operating on a compression refrigerating machine, mini-bars are usually equipped with absorption cooling machine. As the refrigerant is ammonia which reacts with the absorbent — water, transferring the heat of the refrigeration circuit. Such refrigeration equipment operates silently that allows you to use frigobar in hotel rooms, offices and even bedrooms. They are often used in bars or trading rooms of restaurants.

Absorption chillers operating on electricity, less effective than compression, which are used in conventional small refrigerators. Therefore, frigobar typically consume more power than compression refrigerators of similar capacity. Following the General trend of increasing efficiency, manufacturers of mini-bars strive to reduce energy consumption. Some modern frigobar spend her several times smaller than conventional models.
