Maintaining the correct vapor-liquid refrigerant balance is crucial for air conditioning and refrigeration system performance. Longer line sets hold more refrigerant, which increases the risk of liquid accumulating in the suction line or entering the compressor during off-cycles. Heat pumps are one common application that requires additional measures. Refrigerant flow reverses during heating, turning the […]

An important rating on motors is the AMBIENT  temperature rating that the motor can operate at. This rating refers to the temperature of the air around the motor, not the temperature of the motor itself or even the temperature of the outdoor air—since the motor is often in a condenser air stream that is higher […]
