Refrigerant is the working medium in the refrigerator. It is called refrigerant or refrigerant. It circulates in the refrigeration system. In the circulation flow, the refrigeration exchanges energy with the outside world through the change of its own thermal state, so as to achieve control. Refrige... read more
Optimizing refrigerant charge has always been a key part of designing cooling systems and balancing their efficiency, reliability, performance, and cost. But recently, that balance has shifted, and refrigeration engineers are once again looking at refrigerant as a key piece of the puzzle. There are ... read more
Evacuation is often called “vacuum” or “pulling a vacuum,” and it’s one of the most important parts of the HVACR installation and repair process where the refrigerant circuit is involved. Our goal should be to keep the closed refrigeration circuit clean, dry, and tight — just like I was taught since... read more
Refrigerant costs seem unlikely to fall in the near future. Supplies of traditional refrigerants are being reduced, and new alternatives being developed will likely carry the price premium that comes with having limited suppliers and competition. But it is not only the increase in prices that is an ... read more
Why do we need to evacuate an air conditioning system or a refrigeration system? All the refrigeration system are designed to run without moisture and non-condensable gases else it may not work as designed and is likely to fail prematurely. Presence of moisture in the air conditioning system may lea... read more
