Electronic Expansion Valve In Chiller

There are three commonly used types of expansion valve used on a chiller. An expansion valve or expansion device controls the amount of refrigerant that passes between the condenser and evaporator.

We at Maximus Chillers have a comprehensive range of expansion valves on the shelf in our stores at Head Office in Droylsden Manchester.

Electronic expansion valve in chiller. What it does. They are much more sophisticated and allow the refrigeration system to operate much more accurately and efficiently. They work by using a stepper motor that precisely regulates the.

The adjustment range of the liquid. It works to vary the flow based on the change in the cooling load. MOD0188E Module Expansion Valve used on Trane RTAA RTAB RTAD RTHA RTHB RTHC Chiller Models.

Youll usually see electronic expansion valves listed with the acronym of either EEV or EXV. Electronic Expansion Valve Chiller. Carel electronic expansion valves are designed to meet any cooling capacity requirements up to 2000 kW in air-conditioning and refrigeration applications and stand out above all for their excellent flow control even at lower flow-rates.

This is a simple design of a solenoid coil lifting a solenoid valve and opening the diaphragm in the expansion valve. Minimizes required packaging space. This allows the refrigerant to pass from the high.

The EXV can provide a shut-off function as well as accurate proportional refrigerant flow by using a needle valve in accordance to the pressure temperature sensor. A wide variety of electronic expansion valve for chiller options are available to you such as local service location structure and applicable industries.

The electronic expansion valve uses the electrical signal generated by the adjusted parameter to control the voltage or current applied to the expansion valve to achieve the purpose of adjusting the liquid supply. Carel expansion valves have three main strengths. Its purpose is to expand the refrigerant reducing its pressure and increase its volume which will allow it to pick up the unwanted heat in the evaporator.

EXV Chiller Assembly. The expansion valve is located between the condenser and the evaporator. Full range of Stack Plate Refrigerant Chillers from 2 kW to 11 kW.

Assembly leakage checked before shipping. Alternatively the electronic expansion valve EXV is another solution for this application. Electronic expansion valves are an evolution on the thermal expansion valve.

The stepper motor is coupled with a shaft that is connected to a thread. RTA on ChillerPartsae. In this video were going to cover the basic working principles for how an electronic expansion valve wo.

How does an electronic expansion valve work EEV EXV. Electronic expansion valves - Stators cables accessories. Matched performance between EXV and Chiller.

When energised the shaft pushes the thread and then the needle onto the valve seat. There are many different types of expansion valve the most common at the thermal expansion vale the pilot operated thermal expansion valve. Otherwise the pull-down capacity might be insufficient.

For low temperature applications it is recommended to size the electronic expansion valve at 50-60. For low-temperature requirements ask about electronic expansion valves EEVs to give you tight superheat control. From the point of view of the accuracy of the control reducer type electronic expansion valve fully open pulse number of 2000 pls and 1400 pls two the adjustment is extremely accurate while the direct-acting electronic expansion valve generally maximum open degree of 500 pls the adjustment is not as accurate as of the reducer type but generally can meet the needs of our chiller system.
