my question is, why do people in US are so behind in HVAC industry? like you guys seem to live in early 2000s in terms of HVAC.

How do we measure subcool on a vrv

@RomanBaugh Ай бұрын

Depends on the series and mode but we should be measuring subcool using the coil temp leaving the heat exchanger. Not leaving the outdoor unit. Remember the subcooler on the unit will throw this measurement off.

Sorry I’m confused is discharge superheat calculated by taking Discharge line temp-Discharge sat temp or Discharge line temp-Liquid sat temp?

@RomanBaugh Ай бұрын

Discharge, liquid, hotgas, suction, it all doesnt matter. What matters is pressure converted to saturation temp. So call it whatever you want but DSH is leaving compressor temp minus pressure converted to saturation temperature at that same spot. So yes Discharge temp - head pressure converted to saturation temp or Tc.

@jorgevalladares179 7 ай бұрын

Are the examples shown, reflect a system running on heat?

@RomanBaugh 6 ай бұрын

Heat, Cooling, heat recovery it’s all relevant as long as you know the correct locations of where to measure these temperatures.

@garypoplin4599 8 ай бұрын

1:34 - Where do you put your probes to get the numbers for calculating discharge superheat? My understanding of the discharge superheat calculation is discharge line temperature less liquid line pressure (converted to temperature). Is that right?

@RomanBaugh 6 ай бұрын

Discharge superheat is measured using discharge line temperature 6” down stream of compressor then subtracting it from liquid line temp converted to saturation temp. 180-110 = 70 DSH.

Do you know the process of Daikin minisplit, how do they calculate evaporating temp and condensing temp. Since they do not have pressure transmitters. Only discharge probe, ev probe and condensing probes, and air thermistor probes. Do they calculate evaporating and condensing temperatures via the compressor load ampere, and also take into account the heatexchanger probes? Its bugging me for real. Hope you have somewhat of an answer.=)

@ryanbrown7134 9 ай бұрын

Short answer is they don’t. Thermistor data is all that is used to control the motor speeds and valve pulses. At least that’s what is taught in the mini split class.

@guuuuustaf 9 ай бұрын

@@ryanbrown7134 Then how can they get correct sh and sc? Its been bugging me how are they actually know how to adjust the eev. Some of the data needed for correct sh, sc is unknown. They must use ampere drawn by the compressor too trying to get somewhat of correct ev pressure and condensing pressure... 😁

@ryanbrown7134 9 ай бұрын

@@guuuuustaf It bothered me too when I first started working on them. They don’t monitor superheat or subcooling. They may have an algorithm that determines wet operation with compressor current and discharge temp but I doubt it. Even if they did, they wouldn’t tell us anyways. Other than the logic, mini splits are very simple units.

@guuuuustaf 9 ай бұрын

Haha okeey thank you for the answer=). may be therefore they often have two accumulator tanks beside compressor. Cause the sh cant always be 100%.They are indeed very simple. The logic as you say is the more tricky part. @@ryanbrown7134

@Jonathan-li1xh 9 ай бұрын

If the units don’t have the pressure sensor , it should have thermistor at the evap and at the condenser coil . These temperature will be used for evap temperature and condensation temperature instead pressure reading converted into sat temperature.

I’ve got a total of 9 systems of 4X heat recovery units. We have had multiple issues and lost compressors. Your video made me dive deep into these systems. One system in particular is running a high DSH 90-100. SSH is within range no higher that 32 sometimes drops less in five. Subcool is within range. I did an oil differential across the suction line and was getting 7F then jumped up to almost 40F. Do you have any more info. Also where did you get the 30 modes local Daikin rep doesn’t have it.

@RomanBaugh 11 ай бұрын

Sounds like oil traps within the building. High DSH levels with normal range SSH and Subcooling means your compressors are low on oil. Sounds like piping errors or discrepancies. Meaning there are piping rules broken causing oil to become trapped in the system. Your local Daikin Rep will not have that list, as I translated it from Japanese. Daikin Japan is the only one with the list prior to now.

@RomanBaugh 11 ай бұрын

System never runs the compressor over half speed causing velocity to be low not allowing refrigerant to bring oil back from the indoor units. Couple that with liquid flood back then compounds the issue removing any remaining oil from the compressor.
