The anemometer measures air velocity that needs to be averaged over the area of the leak. You went directly to CFM. Did I miss something? The temperature of any air bypassing the evaporator also matters on a real job.

@measureQuick 7 күн бұрын
Then let’s teach them all the calculations. Superheat and subcooling are only a subset. We need to also be able to calculate what the gauge pressure should be before we hook up the gauges, what the temperature split should be before we measure it, what the target superheat should be before we compare it to the actual, etc. We should even do the same with capacity. 90% of the industry can’t do the calculations above.

I’m not an HVAC technician. I just repair and maintain my own HVAC equipment. There’s nothing wrong with using automated tools, especially when they produce better results. I’ve never even used an analog manifold gauge set. My Testo Smart Probes are more accurate and not subject to the arithmetic errors people tend to make. I’m also lazy and would prefer not to have to continuously monitor two pairs of measurements and do subtraction in my head. However, I do own a set of analog manifold gauges and thermocouples in case something ever happens to my Smart Probes. My issue with this as an industry outsider is I don’t think someone who is incapable of calculating superheat and subcooling has a good enough grasp of HVAC fundamentals to be out in the field working on jobs alone. Someone who can enter numbers into TurboTax and produce a correct tax return but doesn’t understand accounting principles isn’t an accountant and shouldn't represent themselves as an accountant. Someone who can use measurement equipment but doesn’t understand what the measurements mean isn’t an HVAC technician. It's a bit ironic that an industry notorious for insisting DIYers are too incompetent to go anywhere near HVAC equipment apparently has technicians working within it who would be lost without a cell phone app to do the thinking for them. I’d be pretty irritated if I called for an HVAC technician, and the contractor charged me $100+ per hour for someone so incompetent they have to call tech support to figure out their probes are swapped. But don’t get me wrong. If a cell phone app can be made foolproof enough that someone who doesn’t understand HVAC fundamentals can use it to diagnose problems as well as a competent technician, I’m all for it. As a consumer, I like the idea of paying mechanic prices for technician results. For the individual doing the work, it’s a bit sad they are deprived of the joy of understanding, but that’s not my problem. Great video, by the way. I enjoy listening to these kinds of discussions between people well practiced in their field. I've learned a lot from both of you.

The HVAC Profession has advanced 1000 fold with MQ which continues to get better and better. My techs are much more productive with MQ. The best feature we all like is the NON invasive mode. It has been a game changer reducing refrigerant loss when connecting gauges during PMs. The use of probes instead of hose to gauge also greatly reduce loss. The EPA should recognize MQ in this regards. Reduce weight of tools on RTUs is another note worthy benefit. We just need a tablet that is direct sun readable for us old folks

13:47 - What are the steps from starting MQ to get to this screen? I’ve gone different routes with the same response. The “gauges” displayed on _my_ screen shows TXV/Superheat on the left and CFM/Air Flow on the right. How can I get the PSIG suction and liquid to show from my connected Fieldpiece probes? I’ve tried Quick charge, start a new project, make a saved project active, as well as other things after opening the MQ app but with the same result. What is the required information that needs to be entered before I can see the pressures from the connected probes displayed. Am I missing a requirement? I have the following probes mapped: liquid pressure, suction pressure, liquid line temperature, suction line temperature, discharge line temperature, outdoor air temperature, return air temperature, supply air temperature, return static, and supply static as well as the iDVM550. The all the probe’s readings are accurately displayed in other parts of the app. For me to see the current pressures, I have to open the toolbox and go to the connected Fieldpiece probes list.

Superheat and subcooling are simple, agreed. But can your techs tell you what the pressures should be before they hook up the gauges? If so do you think they are taking the time to do so? Can they tell you the normalized capacity or airflow? Are they calculating the target temperature split across the evaporator or the target superheat on a fixed orifice system? Are they able to get the measurements fast enough to compensate for the changes in load? Where does it start and where does it end? You can deploy nine probes and by the time the system is stable have an accurate diagnostic and realtime capacity. Technology makes things exponentially easier, faster and far more accurate.

Depends on the port design and length. Some flow more than others. A typical condenser port can flow up to 14 CFM at atmospheric pressure. The port of a FP pump flows about 6 CFM at atmospheric pressure. Some are 1/8” id and some 3/16” that small change in diameter makes a large flow change.
