In ancient times, if someone offered to preserve food for days and return it back in fresh condition (frozen food like peas or corn) they would’ve been accused of witchery. But in reality, it’s just science and that in fact is magical.
Taking the example of a refrigerator, it is a thermal system that works on heat (thermal energy) transfer. A refrigerator transfers heat from inside of itself to outside in order to provide a preserving state for food.
Refrigerator has key components like compressor, evaporator, condenser and expansion valve which help in pumping the refrigerant through the system, absorbing heat and condensing or releasing it outside through the valves.
Thermal systems are engineered structures or big devices designed to control and transfer heat energy. They are crucial as they produce power, manufacture and help with HVAC (heating, ventilation, and air conditioning) and refrigeration.
Some common types of thermal systems are furnaces, heat pumps (heating systems), air conditioners, refrigerators (cooling systems), steam turbines, gas turbines (power generating systems), combined heat and power systems (heat recovery systems), etc.
Thermal systems are essential for a wide range of activities and crucial in industrial places. It could even be considered a vital component of an industrial body due to its ability to manipulate thermal energy in various ways. They help in reducing environmental harm that an industrial body could cause.
