Electronic Expansion Valves
Description
Electronic expansion valves (EEV) are used in a range of refrigeration systems such as commercial cool rooms and walk-in freezers to precisely control the flow of refrigerant into the evaporator. They are an evolution of conventional thermostatic expansion valves (TEV) that use springs, bellows, and pushrods to control the amount of refrigerant released into the evaporator and hold a constant evaporator superheat. The electronic expansion valves is a more sophisticated design and operates with greater precision and efficiency. Electronic expansion valves control the flow of refrigerant entering a direct expansion evaporator in response to signals sent by an electronic controller. This allows the refrigeration system to operate much more accurately and efficiently.

Benefits
(1)More Precise Control
Electronic expansion valves precisely control the amount of refrigerant that flows into your evaporator. As opposed to thermal expansion valves, Electronic expansion valves know far more accurately how much refrigerant flow to increase or decrease based on the information it's receiving. With an electronic expansion valve, superheat is always under control, never fluctuating too high or too low.
(2)Faster Response
Once the order is sent from the controller to the electronic expansion valve about a load change, the response time is significantly faster than through a thermostatic expansion valve.
(3)Higher Visibility and Connectivity
With remote monitoring, operators can see superheat levels, as well as how much refrigerant is flowing without the need to be in the walk-in freezer or cooler. This information can be monitored directly between the electronic expansion valve and the controller.
(4)Flexibility
Electronic expansion valves can also operate with more types of refrigerants than thermal expansion valves, as well as a wider range of capacities and evaporating temperatures.
(5)Energy Savings
With smarter monitoring and accurate control, electronic expansion valves allow refrigeration control systems to operate at optimal levels, without wasting energy through unnecessary defrost cycles and avoiding large temperature fluctuations. All of this leads to a reduction in energy costs.

Uses
(1)Household Air Conditioning Field
The electronic expansion valve can automatically adjust the flow of refrigerant according to the change of indoor air temperature, so that the indoor air temperature is always kept within the set temperature range. Since the flow of refrigerant can be automatically adjusted, the electronic expansion valve can not only make the air conditioner run more efficiently, but also reduce energy consumption and extend the service life of the air conditioner.
(2)Commercial Air Conditioning Field
Commercial air conditioners usually have a large area and require multiple indoor and outdoor units, so the flow of refrigerant needs to be more accurately controlled. The electronic expansion valve can adjust the flow of refrigerant according to the needs of different indoor units to meet the air conditioning needs in different rooms and ensure the best cooling effect of the entire shopping mall, supermarket or office building.
(3)Refrigeration Equipment Field
Refrigeration equipment usually needs to work at extremely low temperatures, and the flow of refrigerant needs to be extremely accurately controlled. The electronic expansion valve has good control accuracy and stability, and can accurately control the flow of refrigerant, thereby ensuring the reliability and stability of the refrigeration equipment.

Pressure Sensor
Description
A pressure sensor is a device or instrument that can measure the pressure in gases or liquids.
