Mechanical Refrigeration Works

The mechanical refrigeration system operates on the principle of compressing and expanding gases. This process allows the system to absorb heat from the environment

  1. The compresor
  1. Condenser
  1. Expansion valve

The expansion valve reduces the pressure

The compresor compresses the refrigeration gas, raising its pressure and temperature

The condenser then cools the gas allowing it to condense into a liquid

Mechanical refrigeration systems are wideky used in various application from household refrigerator and air conditioning units to industrial chillers and comercial freezer

1.Heat absorption mechanism

  1. Cycle of refrigeration
  1. Efficientcy and performance

The cooling effect in mechanical refrigeration is achieved through heat

The refrigeration cycle consist of four main processes. Compression, condensation, expansion, and evaporation.

The efficiency of a mechanical refrigeration system is often measured by its coefficient

Future trends in refrigeration technology

  1. Advancemen in refrigerants
  1. Integration with renewable energy.
  1. Smart refrigeration system

There is growing trend towards using more environmentally friendly refrigerant in mechanical refrigetaion system

The incorporation of smart technology into mechanical refrigeration system is on the rise

Future mechanical refrigeration system are expected to integrate more with renewable enerygy

In simplest terms, the mechanical components in an AC are all the parts that move. For example, it's the fan that blows air, and the compressor for the refrigerant. Think of them as wheels and pedals on a bicycle! The electrical component of your air conditioner is what powers it.

The similarities are they all use a sealed system that operates in the same way, by transferring heat from one place to another. An air conditioner transfers heat to the outside of the room. A refrigerator transfers heat from inside the box to outside of the box.

4 similarities of mechanical and electrical refrigeration.

An air conditioner transfers heat to the outside of the room.

A refrigerator transfers heat from inside the box to outside of the box.

A freezer transfers more heat from inside the the box to outside the box.

An air conditioner will use the most energy. It has to cool an entire room or maybe even a whole house.

4 differences of mechanical and electrical refrigeration

Mechanical refrigeration relies on a compressor and refrigerant for cooling.

Electrical refrigeration uses thermoelectric modules to transfer heat.

Mechanical systems are more efficient for large-scale applications.

Electrical systems are less efficient but require minimal maintenance.

Basic Principle of Electrical Refrigeration

fans

power supply

heat sink

thermoelectric

These solid-state devices use the Peltier effect to create a temperature difference when electric current flows through them, providing the cooling effect.

Provides the necessary electrical energy to the thermoelectric modules for operation.

Used to enhance heat dissipation by improving airflow over the heat sink and the cooled surfaces.

A crucial component that dissipates the heat generated by the thermoelectric module to maintain cooling efficiency.

The basic principle of electrical refrigeration relies on the Peltier effect, where an electric current flows through two different types of conductors, creating a heat transfer. One side of a thermoelectric module absorbs heat and becomes cold, while the other side releases heat. By continuously passing electricity through the system, heat is transferred away from the cooled area, resulting in refrigeration without the need for moving parts or refrigerants.
