When it comes to diagnosing internal component failures in EEVs, we need to be able to bypass the PCB and manually actuate the valves. The EEVMate has the same EEV drivers as those boards, allowing us to see how that valve is operating. In our latest video, Roman shows how to test EEVs in mini-splits and VRF systems using the EEVMate. You can watch it on our website at https://buff.ly/SJRrRAO. You can also go to https://buff.ly/174VDMX to look up product information for the EEVMate and its acces

🔧 What does an EEV do in HVAC systems? This little device, known as the electronic stepper motor, EEV (Electronic Expansion Valve), or electronic metering device, controls how much liquid refrigerant moves through the system. The liquid line comes in, gets metered, flows into the distributor and tubes, passes through the coil, and returns to the suction side before heading back to the compressor. So, an EEV is a type of electronic metering device, which more precisely controls the refrigerant f

This simulation demonstrates a multi-stage waveform generator built using op-amps, producing triangle, sine, and square waves simultaneously. The first op-amp stage acts as an integrator, converting a square wave into a linear ramp, creating the triangle waveform. The second stage shapes the triangle wave into a clean sine wave using filtering and amplitude control. Another stage generates a square wave by comparing the sine or triangle waveform against a threshold, resulting in sharp transition

This simulation shows a sine wave generator built using a Wien-bridge oscillator configuration. The two 1 kΩ resistors and two 1 µF capacitors form the Wien-bridge network, which determines the oscillation frequency—around 159 Hz, matching the oscilloscope reading. The op-amp provides the necessary gain to sustain oscillations, while the 48 Ω and 100 Ω resistors control loop stability and amplitude. As the circuit starts, noise is amplified and shaped into a stable sinusoidal waveform. The oscil

Eev mate, a way to check electronic expansion valves. 1st is the magnets manually controlling and the second is an electronic controller. This is not sponsored in any way. I have not personally used those in the field. What do you think? What do you use ? #hvac #hvacr #hvactools | Ty Branaman

An Electronic Expansion Valve (EEV) regulates refrigerant flow in HVAC systems, improving efficiency and performance. It uses electronic sensors to monitor pressure and temperature, adjusting the valve opening accordingly. This precise control enhances system responsiveness, energy efficiency, and comfort. EEVs are commonly found in modern air conditioning and refrigeration applications. #ElectronicExpansionValve, #HVAC, #Refrigeration, #EnergyEfficiency, #CoolingSystems, #ClimateControl, #Smart
