Q:

How does an absorption chiller work ?

A:

Quick Answer

An absorption chiller works by using a compressor to boil vapor out of a solution of water and lithium bromide. The refrigerant vapor is then compressed to a higher pressure.

Full Answer

The chiller relies on the compressor to complete all the processes. In the process of cooling, two fluids are used: an absorbent and a refrigerant. Water is usually used as the refrigerant and can change into water or vapor easily in the system at different stages. The chiller also depends on heat to run the process. Water boils at a lower temperature and pressure due to its high affinity for the absorbent, usually ammonia or lithium bromide.

    How does a blast chiller work?

    A:

    Blast chillers rapidly cool food by circulating cold air through the unit until temperatures fall to safe levels. They are designed to lower the temperature of cooked foods quickly enough to minimize bacterial growth, ensuring the food is out of the 40 to 140 degree Fahrenheit danger zone within 90 minutes, rather than the hours it can take when foods are stored in a refrigerator.

    How does an air compressor unloader valve work?

    A:

    Air compressor unloader valves work by releasing air that is trapped in the compressor's pipe and piston once the pressure switch trips the power supply to turn the compressor off. By releasing the trapped air in the piston, the compressor motor is able to start properly. If the trapped air is not released, the compressor's piston remains under pressure, making it difficult for the motor to start.

    How does a refrigerator relay work?

    A:

    A refrigerator relay, or start relay, jump-starts the refrigerator's compressor. Without the relay, no electrical charge is delivered to the compressor and the refrigerator does not cool. Relays usually make a loud clicking noise when they are in need of repair or replacement.
