- About RLA | HVAC-Talk: Heating, Air Refrigeration Discussion
What mean RLA? I know that literally mean Rated Load Amperage, but my question is what really means Example: a compressor nameplate say RLA=16, but an ammeter say amperage values are 8 3, 8 3, 8 6 (is a three phase motor) when the unit is running, and pressure is fine, sight glass is full
- rla lra | HVAC-Talk: Heating, Air Refrigeration Discussion
whats the differance in these two? i know they are run load amps and load run amps but there is a big differance in the numbers my understanding is that rla is the amps being drawn while running but what is lra?

At ARI Standard 320-86 rating conditions of 80F dry bulb 67F wet bulb entering air and water entering at 85F and leaving at 95F when cooling, and 70F dry bulb entering air and water entering at 70F when heating
- RTHDs oil loss Capacity Limited By Low. . . - HVAC-Talk
12 degree approach @ 40% RLA is a problem for me, either you have some really fouled evap tubes, extremely low flow or your refrigerant is saturated with oil, you say the machine has failed many times on loss of oil, have any idea how much oil has been added to the machine?
- For a system carries receiver, no liquid found in the. . .
I checked the both coil were clean, the fans are both running, the compressor amps (14 amps) is lower than RLA (17 amps) is any possible has a restriction in the system? thank you! PS: For a system carries receiver, no liquid found in the sight glass, is this normal or abnormal?

We experienced major hail damage to our commercial building and 4 older Carrier RTU's, 10, 15, 15 and 25 ton The units have been maintained with PM 4x per year Even after attempted combing by our Tech one (15T) failed a month after the storm We could not wait for an entire prepackaged

- Air conditioning Unit start problem - HVAC-Talk
Compare amps to listed RLA Of course you're changing the pot relay with capacitor change Is old relay still operational, or did the points weld? Do caps have bleed resistors? I think that you may have an extremely short cycle killing these caps perhaps during a night cooling call? Any more than 6 cph will allow heat buildup in start
