3 Ways to Reduce Compression Ratio in a Heat Pump

We’ve talked about compression ratio a lot over the years. Compression ratio is the number you get when you divide the absolute head pressure (PSIG + 14.7) by the absolute suction pressure (PSIG + 14.7). It measures the efficiency of a compressor, and lower numbers indicate that the compressor is moving more refrigerant while consuming […]

Best Practices to Conserve A2L Refrigerants in a Shortage

If you own your HVAC company or are involved in management, you may have realized that our industry is currently facing a shortage of new A2L refrigerants, particularly R-454B and R-32. Our own company has faced limited availability and long lead times, mainly due to supply chain disruptions and the increased demand now that our […]

Wet Bulb and Enthalpy – The Left Side of the Chart

It's incredibly useful to understand wet-bulb temperature and air enthalpy when calculating actual system capacity and human comfort. Dry-bulb temperature is a reading of the average molecular velocity of dry air. However, it does not account for the actual heat content of the air or the evaporative cooling effect of the air. When air is […]
