Electronic Expansion Valve In Chiller
This is a simple design of a solenoid coil lifting a solenoid valve and opening the diaphragm in the expansion valve. 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 Valves The Basics
An expansion valve or expansion device controls the amount of refrigerant that passes between the condenser and evaporator.
Electronic expansion valve in chiller. For low temperature applications it is recommended to size the electronic expansion valve at 50-60. Carel expansion valves have three main strengths. Electronic expansion valves - Stators cables accessories.
In this video were going to cover the basic working principles for how an electronic expansion valve wo. When energised the shaft pushes the thread and then the needle onto the valve seat. EXV Chiller Assembly.
Minimizes required packaging space. 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. There are many different types of expansion valve the most common at the thermal expansion vale the pilot operated thermal expansion valve.
What it does. 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. Otherwise the pull-down capacity might be insufficient. Electronic expansion valves are an evolution on the thermal expansion valve.

Full range of Stack Plate Refrigerant Chillers from 2 kW to 11 kW. This allows the refrigerant to pass from the high. Matched performance between EXV and Chiller.
A wide variety of electronic expansion valve for chiller options are available to you such as local service location structure and applicable industries. The adjustment range of the liquid. The stepper motor is coupled with a shaft that is connected to a thread.
They work by using a stepper motor that precisely regulates the. 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. 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.
They are much more sophisticated and allow the refrigeration system to operate much more accurately and efficiently. 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. 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.
The expansion valve is located between the condenser and the evaporator. Alternatively the electronic expansion valve EXV is another solution for this application. There are three commonly used types of expansion valve used on a chiller.
Assembly leakage checked before shipping. For low-temperature requirements ask about electronic expansion valves EEVs to give you tight superheat control. How does an electronic expansion valve work EEV EXV.
