The refrigerant is discharged through the discharge line (the smaller line) and the temp is raised due to high pressure. The outdoor fan passes over the condenser coil witch turns the high temp, high pressure vapor in to a lower temp, liquid (same psi). The liquid is then further ''sub-cooled" to ensure the refrigerant is fully condensed before flashing off through the metering device where it is turned into an even lower temp, and the pressure drops aswell into a saturated mixture.. RSI student. hope that helps you buddy. The refrigerant is super heated before entering the compressor to ensure no liquid is entering the compressor, witch will ultimately destroy it.

CAN U PLS SUGGEST A CUCLE WHICH DOES NOT USE A COMPRESSOR AS WORK INPUT BUT STILL HELPS TO COOL DOWN THE PRODUCT.PLS REPLY .....ITS URGENT.....

All new and interesting to me. I need to learn as much as possible to keep my job and work efficiently to keep my budget low and prove my worth at my job. This is very good information and anything else you have would be greatly appreciated. I am currently enrolled online Ashworth hvac course. All new and interesting to me.

For as many times as I've looked at the refrigeration cycle it never seems to sink in. One thing struck me with JD asking about superheat, in that superheat does not equal super "hot". It just refers to the fact that the refrigerant has absorbed enough heat to make it a gas and then absorbed a little more before leaving the evaporator. I believe this is more obvious when you are looking at a P-T diagram. Keep up the good work. Great explanation Dave.

And it was stated on the tools page normal operating conditions in Florida are 250 high side 70 low side , im guessing this is for R-22 is it different for R-410a ? At which points in the cycle does the refrigerant become superheated and subcooled ?
