November 2, 2015
The Q-Sync Smart Synchronous Motor represents a new class of energy efficient motors that are designed to reduce energy consumption while improving the power quality and reliability of fan motors, according to the manufacturer, QM Power.
We all know the refrigeration industry isn’t an easy one. There’s competition, pressure from customers, challenges finding good people, and much more. At such times, it’s important to not lose sight of how far the refrigeration industry has come.
It’s easy in the HVACR business to get caught up in and maybe even a little overwhelmed by all the technology and regulations and rapid-fire changes — especially in the refrigeration sector. It’s important, however, not to let all the pandemonium make you lose sight of the human side of the business.
If refrigerant migration occurs in a system that has a crankcase heater, the vapor will be forced away from the crankcase and end up in the suction line. This refrigerant may condense in the suction line and cause slugging in the compressor’s cylinders on startup.
Thinking in temperature in-stead of pressure can help make the crossover to a new refrigerant much easier. The next time you’re faced with determining the correct operating evaporator or condensing pressure, think in terms of temperature and then convert it to pressure.
A new report has found that the environmental challenge caused by booming global demand for refrigeration could be far greater than previously thought. Due to changing demographics, particularly in Asia, the number of refrigerated vehicles on the road could feasibly reach 15.5 million by 2025, up from less than 3 million in 2013.
