Ammonia Refrigeration Plant Operator Interview Questions and Answers

Refrigeration is a process of removing heat from a space or substance to lower its temperature. Compressors are used to increase the pressure of refrigerant gas.

• Refrigeration is the process of removing heat from a space or substance to lower its temperature.

• Compressors are used to increase the pressure of refrigerant gas, which then flows through the system to absorb heat and cool the space.

• There are different types of compressors used in refrigeration systems, such as recipr...read more

Refrigeration gas works by absorbing heat from the surroundings, lowering the temperature, and then releasing the heat elsewhere.

• Refrigeration gas is compressed to increase its temperature and pressure.

• The hot gas then flows through a condenser where it releases heat and condenses into a liquid.

• The liquid refrigerant passes through an expansion valve, reducing its pressure and temperature.

• The cold liquid then absorbs heat from the surroundings, such as air or water, causing i...read more
