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.
