Refrigerants can be divided into three categories: single working fluid refrigerants, non-azeotropic mixed refrigerants, and azeotropic mixed refrigerants. No matter whether the single-working-substance refrigerant is gaseous or liquid, its composition will not change, so it can be charged into gase... read more
Analysis of physical properties and advantages and disadvantages of R410A R410A is a HFCs refrigerant mixed with two working fluids of R32 and R125 at a mass fraction of 50% and 50%. R410a refrigerant is non-flammable, ODP is 0, and global warming coefficient value GWP is 2340, so R410a is not a tru... read more
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
