It’s not everyday you get to buy a new AC unit, I though it would be a good idea to finally take some thermal images of the coils that do all the work in a heat exchanger.
🔵 condenser unit (outdoor), placed near window
📋 Data Sheet ( as per manufacturer ).
-
GREE GSH-12PUV410, 1 Ton.
-
Inverter.
-
12000 BTU.
-
Hot + Cold.
-
Refrigerant Type - R22
-
Operating current : 6.0 Amp
-
Power Consumption : 1250 Watt.
Since I had a amp meter, I did a site reading of the operating currrent. My main’s voltage was 218V, while my amp meter was showing Amin ~ 2.1 and Amax ~ 6.2 Amp.
So it seems my AC unit was consuming ~ 460 Watts while operating at it’s low setting, and 1,351 Watt at full capacity.
Now time to take some thermal images …
🔵 outdoor unit / thermal image ( distant )
🔵 close up of colder coil in unit, temperature difference of ~10°C between coil.
🔵 using red, outdoor temperature is 30°C, hottest coil is at 46°C. ( 16°C differential ).
The images was taken after 2 hours of operation, to give the AC time to fully pass on the gasses into all the coils, it was quite peculiar to see two coils being ~ 6 degree colder than the others, was there some sort of blockage, preventing the gas from reaching ?
I did not expect there to be cold coils in the condenser unit at all, especially since it’s a brand new unit !
I had so many questions, is it normal for condenser coils to have thermal gaps ? especially new units ?
