"Refrigerant System With Control To Address Flooded Compressor Operation"
Abstract: A suction modulation valve is throttled when conditions in a retngerant system indicate that an undesirable amount of liquid refrigerant might otherwise be delivered to the compressor. As an example, the throttling would occur at startup, among other conditions. Throttling the suction modulation valve reduces the amount of refrigerant reaching the compressor and thus ensures that any liquid refrigerant would be likely "boiled off' before raising any problems in the compressor. Other control steps can also be performed to alleviate flooded compressor operation with liquid refrigerant. Such steps , for example, can consist of: actuating heaters, discharge valve throttling, by-passing refrigerant from intermediate compression point back to suction, controlling the speed of the condenser fan can be performed independently or in combination including the suction modulation valve throttling.
