HVAC Buddy® GridBuddy|商業線上App不用買-HotApp4Game

HVAC Buddy® GridBuddy is a tool for professional technicians to differentiate themselves from the "Gas and Go" crowd. By utilizing standard measurements and observations that should be recorded on any service ticket GridBuddy helps assess refrigerant charge, coil characteristics, total electrical demand, and total cooling capacity. Calculate baseline and incremental operating costs before, during, and after servicing. Send a summary email report of results.If you are looking for a superheat, subcooling, and airflow app see HVAC Buddy. GridBuddy literally has 10 times the functionality of HVAC Buddy but more complexity. As one reviewer noted this app takes some time to learn and is not for the novice.Downloading this app ONLY gets you R11 and R12. Up to 95 additional refrigerants and the ability to change entering air wet bulb are available as in-app purchases.The following are calculated:SuperheatSuperheat Target TempSubcoolingSubcooling Target TempAirflow (ETD)Airflow TargetCFM per TonSensible Heat RatioApparatus Dew Point TempCoil Bypass FactorCondenser Compressor EnergyCondenser Fan EnergyLiquid Saturation TempCooling TonsCondensing Temp over AmbientCFM Per TonCoil Latent EnergyCoil Sensible EnergyCoil Total BtuHEvap Enthalpy DeltaEvap Entering Air Mass Flow RateEvap Entering Air EnthalpyEvap Entering Air Specific VolumeEvap Fan EnergyEvap Leaving Air Mass Flow RateEvap Leaving Air EnthalpyEvap Leaving Air Specific VolumeVapor Saturation TempEvaporator Temp DeltaEvap Entering Air Rel HumEvap Leaving Air Rel HumUnit Total EnergySEER Annual Cooling CostsEEREER Annual Cooling CostsFocus on what the numbers are indicating and not on trying to remember the chronology of what's been done and calculating values.BaseliningDuring the course of diagnosis, repair, and re-evaluation copy and save as many sets of data as needed. Establish a baseline and annotate each one (i.e. "added 2lbs refrigerant") so you have a trail of actions and results. Select any two of these for your operating report.Side By Side CompareThe Comparison View shows any two selected sets of measurements side by side complete with every input and calculated value. The comparison shows absolute and percent differences.Cost SavingsEmail an invoice style summary presentation of the data collected on system performance. For maximum value enter the electricity cost per kilowatt hour, annual cooling degree days, and hours per day for your area to get annual cooling costs. Show annual savings by upgrading to a higher SEER by pressing "copy unit" and changing the SEER value on the new unit. Use comparison to show cost savings as a result of servicing (i.e. clean coil, proper charge, etc.).In App PurchaseAll calculations and features in GridBuddy are fully functional for a return air wet bulb temperature of 63 degrees Fahrenheit and refrigerants R-11 and R-12. This means GridBuddy is an excellent training tool to learn pressure temperature relationships, airflow, energy efficiency, and various psychrometric properties of moist air streams.In-App refrigerant purchases are grouped as follows:1) All less than R4002) R400 and greater3) All refrigerantsPurchasing options one and two are the same as option three which is discounted. Any refrigerant purchase opens up the list of available entering air temperatures.About:HVAC GridBuddy is part of the GridBuddy Suite of applications for the HVAC/R industry.
