Electronic expansion valve and driver kit

What is an electronic expansion valve?

The electronic expansion valve, which is one of the important components of the refrigeration cycle, is a mechanism to control the flow rate of refrigerant in refrigeration systems.

In the past, in order to create coolness in the evaporator in the refrigeration cycle, the high-pressure liquid refrigerant was suddenly expanded by mechanical equipment.

These mechanical devices included a capillary tube or a thermostatic expansion valve.

Why is the electronic expansion valve used?

Today, the following factors have caused HVAC engineers to use electronic expansion valves more and more.

Better feeding of the evaporator

Decreased super heat average

quick response

Increased stability

consistent behavior

No need for periodic adjustments

More adaptation to changes in cooling load

behavior according to the function of the control unit

 

Equipping the cooling cycle of air conditioning and refrigeration devices with the electronic expansion valve of CAREL Italy reduces the amount of energy consumption and their optimal performance.

CAREL electronic expansion valve

CARELs electronic expansion valve is capable of meeting cooling needs up to 2000 kW in air conditioning and refrigeration cycles. This equipment works best in the whole flow control process, even in low flows.

CAREL expansion valves have three main functions:

 

  • Reliability over time: The standard design process used for CAREL expansion valves includes lifetime testing. It also guarantees domestic and international standards. Compliance with these standards guarantees the maximum quality of the product and the production process and a continuous commitment to improving the environment.

 

  • Accurate control: electronic controllers, especially through optimization of air conditioning and refrigeration systems management, also guarantee energy savings. In addition, very precise control also guarantees the moving elements with a special shape and controls the flow in an Equal Percentage way. It also guarantees movement during the stroke, using stainless steel bearings and the use of high-precision mechanical parts.

 

  • Complete closure of the refrigerant flow path: in the CAREL electronic expansion valve, the moving element is non-rotating despite the rotation of the motor. This is done using a high-quality Teflon “water seal”. This sealing on the valve prevents any leakage.  To improve the sealing of the expansion valve CAREL Company has installed a flexible steel spring.
