The working principle of chiller is to circulate the coolant through the mold to absorb heat, then cool it in the evaporator of the chiller and then circulate it.

The chiller is an important component of the die casting process, ensuring that the molten metal solidifies quickly and evenly.

Understanding the Working principle of chiller is essential to optimizing die casting operations.

Components of a Chiller System

A typical chiller system consists of:

• Compressor: compresses the refrigerant, raising its temperature and pressure.
• Condenser: hot, high-pressure refrigerant gas cools here and condenses into a liquid.
• Expansion valve: liquid refrigerant passes through this valve, where its pressure and temperature decrease, turning into a cold, low-pressure liquid.
• Evaporator: the cold refrigerant absorbs heat from the mold, cooling it. The refrigerant then evaporates back into a gas.
• Circulating pump: this pump circulates the coolant (usually water or a special liquid) through the mold, absorbing heat and then being cooled by the evaporator.

Working principle of chiller

The main function of a water chiller is to cool the die casting mold quickly and efficiently. Here is how a water chiller works.

1.Coolant Circulation: The chiller circulates a coolant (usually water or a special liquid) through the die casting mold. This coolant absorbs heat from the mold.

2.Heat Absorption: As the coolant flows through the channels in the mold, it absorbs heat, helping to quickly cool the molten metal inside the mold.

3.Return to the Chiller: The heated coolant then returns to the chiller, where it passes through the evaporator.

4.Refrigeration Cycle: Inside the chiller, the refrigeration cycle involves the coolant giving up heat to the refrigerant. The refrigerant then evaporates, absorbing the coolant’s heat and cooling it down.

5.Compressor and Condenser: The refrigerant gas carrying the absorbed heat is compressed by the compressor, raising its temperature and pressure.

The hot, high-pressure refrigerant gas then flows to the condenser, where it cools and condenses back into a liquid.

6.Expansion and Recirculation: They reduce the pressure and temperature of the liquid refrigerant by passing it through an expansion valve, turning it into a cold, low-pressure liquid. This cold refrigerant then returns to the evaporator to repeat the cycle.

7.Working Principle of Chiller – Efficient Cooling: They pump the cooled coolant back into the mold, continuing the circulation and maintaining a controlled temperature crucial for casting quality and consistency.
