Introduction

Electric drinking water coolers are widely used appliances that provide instant access to chilled water. They operate by utilizing electrical energy to remove heat from the water, cooling it to a desirable temperature. Understanding their operation involves exploring the refrigeration principles and the components involved.

Principles of Operation

The primary principle behind an electric drinking water cooler is refrigeration, which is achieved through the use of a vapor-compression cycle. This cycle involves the evaporation and condensation of a refrigerant to absorb and dissipate heat.

Key Components of an Electric Drinking Water Cooler

1. Compressor: Compresses the refrigerant, increasing its pressure and temperature.
2. Condenser Coil: A series of pipes where the refrigerant dissipates heat to the surroundings and condenses into a liquid.
3. Expansion Valve: Reduces the pressure and temperature of the refrigerant, allowing it to enter the evaporator.
4. Evaporator Coil: The area where the refrigerant absorbs heat from the water, cooling it effectively.
5. Cooling Reservoir: Stores the chilled water, maintaining its low temperature until dispensed.

Cooling Cycle Process Explained

During the cooling cycle, the compressor compresses the refrigerant, pushing it through the condenser coil where heat is released. The now-liquid refrigerant passes through the expansion valve, reducing its pressure and temperature. Entering the evaporator coil, it absorbs heat from the water, cooling the water and evaporating the refrigerant back into a gas, which is then cycled back to the compressor.

Performance Parameters and Analysis

Performance of an electric water cooler is typically measured via its cooling capacity and efficiency. The average cooling capacity is between 8-10 liters per hour, with energy consumption varying from 75-100 watts. Energy efficiency is critical, often calculated using the ratio of cooling capacity to power input (COP - Coefficient of Performance).
