6.5 HP air conditioning system

: 7bit
Some time back someone asked about one of my system here in my home in the tropics in Queensland Australia.
So here is some data I logged today.
I was actually charging the unit after repairing a leak (darn O rings !) So while charging it up I logged some data
We have had a few weeks of day maximums of around 34 c temperatures (around 93 f). Humidity 55 to 60 % so the house is fairly hot, being a brick home.
We are approaching the wet season and so the weather will get a bit hotter and more humid.
The system is a Carrier 06DA818 compressor (6.5 hp) with a slightly oversized condenser to keep the head pressure low.
The fan coil unit is sold as a 4 to 6 ton unit. Both the condenser and the fan coil units were made here in Australia, so quoting model numbers would be a waste of time.
So today I ran these tests, it was a bit slow in cooling down the are conditioned area as I was charging it at the time.
The refrigerant is R22.
In the lounge there is a 6 foot x 2 feet x 2 foot aquarium which the water in it was about 33 c (about 90 f) which means it radiated heat to be removed by the air conditioning unit.
The cooling was set for 25 c (about 77 f) the original temperature in the lounge and kitchen that are service by this system was 32 c (around 89 f) and 70% RH. It took around one and half hours to cool down to the set temperature. Both the lounge are and the kitchen area are large rooms.
OK the readings were.
Outside air 34 c (around 93 f)
Humidity outside Around 65 % RH
Suction pressure 75 PSI Discharge pressure 240 PSI Oil pressure 20 PSI
Current draw on the compressor was around 9 amps per phase (415 volt, 50 cycles)
I estimate the cooling capacity of this system to be around 75, 000 BTUs, (around 6.25 tons) based on the compressor capacity
The condenser has 2 x 3 phase fans motors on it and I have set them up to run on star and also delta giving head pressure control the star being slower and delta faster, there are 4 pressure switches to say which fan runs how. The condenser is a bit oversized to keep the head pressure down.
The duck work is pretty generously sized to give reasonable air quantities and quiet air flows.
I had to put a larger evaporator fan motor in to get the right amount of air.
My business used to make our own fan coil units but alas I sold off all the gear years ago before installing this system.
Hey I had to get the system going so we would have a cool area for Christmas dinner, enjoy yours.
