HVACR service technicians find themselves at the forefront of the refrigerant transition in AC and commercial refrigeration. As hydrofluorocarbon (HFC) refrigerants with high-global warming potential (GWP) are being phased down, mildly flammable A2L refrigerants have been identified as potential lower-GWP alternatives. But information about A2L servicing requirements is largely unknown in the U.S., which raises many questions within the technician community. If you’re an HVACR technician, the chances of soon encountering A2Ls is very likely. It’s important to gain a better understanding of A2Ls to maximize safety and assist your customers with installation and service calls.
For heating and cooling your home, the compressor is one of the most important parts of your HVAC system. To maintain the optimal balance of temperature, humidity, and air quality levels, there is no better solution for your home’s comfort than an HVAC system powered by a scroll compressor.
With the transition to lower GWP refrigerants, you may wonder what this means for both your existing systems and for systems purchased ahead of the transition. We’ve outlined a few of the main differences between refrigerants along with some additional guidance on why selecting the correct refrigerant for the desired application matters.
To protect against floodbacks on systems vulnerable to liquid refrigerant damage such as heat pumps, the accumulator’s function is to intercept the liquid refrigerant before it can reach the compressor.
