Plastic Injection Molding Magnet Component in Electronic Expansion Valve for Air-condition

Plastic Injection Molding Magnet Component in Electronic Expansion Valve for Air-condition

Features and benefits of injection molded NdFeB
* Injection molded magnets can be of very complex shapes with high precision, typically, tolerance is+/-0.005mm, it is suitable for high precision parts
* It is a new technology to achieve adjustable magnetic properties, composite molding, elastic magnetization and high mechanical strength
* By doing insert molding, magnetic material can be directly molded into or onto other assembly components without further assembly process
* Magnetic powder is neodymium-iron-boron (NdFeB), either isotropic or anisotropic. And Polymer binders utilized are PA6, PA12 and PPS
* Anisotropic NdFeB powder achieves the highest magnetic force as injection molded magnet. And it is possible to achieve BHmax 17GMOe, and can replace some of sintered products
Applications
(Super) Compact Motor, Actuator, Compact Sensor, Motor, etc.

How do Electronic Expansion Valves work? In this article we’ll be discussing how electronic expansion valves work, covering the basic working principle, where to locate them in a refrigeration system and why you should use them. This covers a simplified version to help you learn HVAC basics.

All HVAC/R systems can benefit from the most comprehensive series of electronic expansion valves on the market. The Danfoss portfolio makes it possible to keep up with increasing environmental concerns and tighter CO2 emission regulations, while enabling significant energy savings and cost reductions.

Electronic Expansion valves are used in refrigeration systems to precisely control the flow of refrigerant into the evaporator. You can find these on everything including
VRF units
Inverter mini splits
Heat pumps
Chillers
AHU coils
Etc.

We previously covered how thermal expansion valves work, these are very common in refrigeration systems but they are no where near as efficient or precise as an electronic expansion valve.

Thermal expansion valve vs electronic expansion valve
Electronic expansion valves are an evolution on the thermal expansion valve. They are much more sophisticated and allow the refrigeration system to operate much more accurately and efficiently. You’ll usually see electronic expansion valves listed with the acronym of either EEV or EXV. They both mean the same thing it just varies by manufacturer.

Benefits of using an electronic expansion valve
There are many benefits to using an electronic expansion valve and I’ve listed some of the main ones on screen now. The focus though is usually that by using these expansion valves you’re going to reduce energy consumption from the refrigeration system and well as gaining better performance.

Precise control
Fast and accurate response to load change
Wider part load variation than TXV
Maintains maximum capacity control even at part loads
Injects exactly the right amount of refrigerant
Energy savings ~15%
