Introduction

David N Shaw is a notable inventor based in Manlius, NY (US), recognized for his contributions to the field of refrigeration technology. With a total of 9 patents to his name, Shaw has made significant advancements that enhance the efficiency and functionality of refrigeration systems. His work primarily focuses on improving compressor operations and oil management in refrigeration applications.

Latest Patents

One of Shaw's latest patents is the electronic slide valve block, which addresses the issue of oil loss in screw compressors during low capacity operation. This innovation compares the apparent suction temperature to the temperature of the water exiting the evaporator to determine the apparent superheat. When the apparent superheat reaches a predetermined level, the loading is increased, and an electronic slide valve block is initiated to prevent further unloading. This allows for loading to be initiated in a fixed amount, incrementally, or on a pulsed basis.

Another significant patent is the oil separator, which supplies oil-laden refrigerant tangentially into an oil separator for primary oil removal, followed by a coalescer for secondary oil removal. The flow between the oil separator and coalescer is controlled by a valve to ensure a rapid build-up of pressure in the sump, which is crucial for adequate lubrication of the compressor.
