Clearly understand main equipment in refrigeration system help you easily identify problems during use. Each part has its own role and cannot be replaced. The following article by Tan Long will compile information about the device and how it works for your reference.
Uses of industrial refrigeration systems
Refrigeration system Industrial refrigeration has high applicability in refrigeration, chemical, and food preservation industries. It helps cool and preserve products for a long time without damage, especially effective for large areas and large quantities of goods.
Nowadays, there are many types industrial refrigeration system with diverse capacities to meet user needs. The product has high durability and stable operation, suitable for many different devices.
Main equipment in refrigeration system (Function, structure, Operation)
Refrigeration system includes many important devices, each device has its own role to help the system operate stably:
Evaporator and evaporator fan
- Function:
Condenser is one of main equipment in refrigeration system, has the task of absorbing heat from the air inside the space, converting hot air into cold air. This is where the heat exchange process mainly takes place, helping to reduce the temperature of the space that needs to be cooled.
- Structure:
Consists of copper gas pipes running alternately with aluminum fins to optimize heat conduction. These aluminum fins are designed with many gaps to enhance the heat exchange capacity between the refrigerant and the air.
- Work:
Hot air from the space to be cooled is drawn through the evaporator fan. Refrigerant The inside of the copper tube absorbs heat from the air, lowering the air temperature before blowing it back into the space that needs cooling. This process occurs continuously, ensuring that the air in the space is always maintained at a lower temperature.
Condenser and condenser fan
- Function:
The condenser is responsible for releasing the absorbed heat from the space to the outside environment. This is where the refrigerant releases heat after taking heat from the air inside the space.
- Structure:
Similar to the evaporator, the condenser also includes copper pipes and aluminum fins, but the design of the condenser focuses on optimizing heat dissipation to the outside environment.
- Work:
The refrigerant that has absorbed heat is compressed and transferred to the condenser. Here, the condenser fan blows air through the aluminum fins, cooling the refrigerant and releasing the heat to the outside environment. This process helps the refrigerant return to a cold state, ready for the next cycle.
Gas pipe
- Function: Transport refrigerant between the condenser and evaporator.
- Structure: Pipes are usually made of copper to withstand pressure and temperature, size varies depending on system capacity.
- Operation: Refrigerant is transported from the evaporator to the condenser through pipes, and vice versa.
Compressor
- Function: Compressor is one of main equipment in refrigeration system has the function of sucking gaseous refrigerant from condenser and compressor They are converted into liquid form to circulate in the system.
- Structure: Consists of a piston or compression scroll to perform the compression process.
- Work: The compressor creates high pressure, which helps push the refrigerant through the condenser to release heat.
Throttle valve
- Function: Regulates the pressure and temperature of the refrigerant as it moves from the condenser to the evaporator.
- Structure: There is a small hole that regulates the amount of refrigerant passing through.
- Work: The refrigerant passing through the valve will expand and decrease in temperature, creating low pressure mist to cool the evaporator.
Capacitors and thermal relays
- Function: Protects the compressor from overheating.
- Structure: The capacitor helps start the compressor, the thermal relay cuts off the power when the compressor overheats.
- Work: Relay monitors compressor temperature, cuts power when needed to protect motor.
Starter device
- Function: Helps the compressor start when the system is powered.
- Structure: Consists of coils and contacts to open and close the electric current.
- Work: Close the circuit when there is power, start the compressor.
Temperature sensor
- Function: Measure and control system temperature.
- Structure: Sensors mounted on the evaporator and gas pipe.
- Work: The sensor shuts down the system when the temperature reaches the required level and restarts it when needed.
Ice Discharger
- Function: Prevents the evaporator from freezing, ensuring efficient system operation.
- Structure: Consists of heating rods or mechanical parts to remove ice.
- Work: Defrost when the temperature is too low, ensuring that the performance of the condenser is not affected.
Control Panel
- Function: Manage the operation of the refrigeration system.
- Structure: Includes control buttons and temperature display.
- Work: Set and monitor temperature, adjust system as required.
Main equipment in refrigeration system plays an important role in maintaining the performance and prolonging the life of the system. Regular inspection and maintenance helps to detect problems early and maintain the efficiency of the system.
