4: ammonia condense
5: pressure balance pipe
6: liquid ammonia pipe
7: evaporator (inside cabinet)
8: ammonia gas pipe
9: absorber (water absorbs ammonia)

Basic Principles

Absorption cooling uses heat to create a cooling effect. It relies on a refrigerant and an absorbent. The refrigerant evaporates, absorbing heat and creating a cooling effect through absorption refrigeration technology and the absorption process with ammonia.

The absorbent then absorbs the refrigerant vapor. This process removes the heat from the system. Heat sources for this process can include gas burners or solar energy, featuring absorption refrigeration technology and ammonia.

Components Involved

An absorption cooling system consists of several key components:

  • Generator
  • Condenser
  • Evaporator
  • Absorber

In the generator, heat is applied to the absorbent-refrigerant mixture in absorption refrigeration technology involving the absorption process with ammonia. This causes the refrigerant, such as ammonia, to vaporize and separate from the absorbent in absorption refrigeration systems and absorption minibars.

The vapor then moves to the condenser, where it cools and turns back into liquid in absorption refrigeration using ammonia. This liquid refrigerant flows into the evaporator.

Function in Minibars

Absorption minibars use these principles to keep items cool. They are common in hotel rooms due to their quiet operation and reliability, ensuring a peaceful stay for guests with minimal noise.

When the liquid refrigerant enters the evaporator, it absorbs heat from inside the absorption minibars in hotel rooms for guests using ammonia refrigeration. This evaporation process cools down the minibar’s contents.

The resulting refrigerant vapor is absorbed by the absorbent in the absorber section of the absorption minibar in absorption refrigeration using ammonia without noise. Then, it returns to the generator, completing the cycle.

Energy Efficiency

Absorption cooling systems using ammonia are often more energy-efficient and produce less noise than traditional compression systems. They use waste heat or low-grade thermal energy as their primary source in rooms for guests, reducing noise and ammonia.

This efficiency makes absorption minibar options environmentally friendly for hotels looking to reduce energy consumption and noise for guests.

Practical Applications

Hotels benefit from using absorption minibars because they are silent, efficient, and do not disturb guests with noise or ammonia. They do not have moving parts like compressors found in traditional refrigerators or a hotel mini fridge, such as an absorption minibar, reducing noise for guests and using ammonia.

This lack of moving parts reduces maintenance needs, minimizes noise, and prolongs lifespan, making it ideal for guests using an absorption minibar. They operate without electricity, making them ideal for locations with unreliable power supplies, such as an absorption minibar for guests that minimizes noise.
