  • Patent number: 10563893
    Abstract: Apparatuses, methods, and systems for adjusting scale(s) of a refrigerant recovery system (RRS) are described. The RRS can determine pressure and weight measurements of content within a refrigerant storage tank. The RRS can determine weight measurements of content within oil storage containers. The RRS can compare the pressure and weight measurements to thresholds to determine whether the scale(s) require adjusting, whether the RRS should be locked to prevent further use of the RRS until after servicing of the RRS, or whether additional functions of an operating state of the RRS should be performed. The RRS can comprise a processor to automatically adjust the scales, determine the pressure and weight measurements, and compare pressure and weight measurements to the thresholds. Locking the RRS can prevent the RRS from recovering refrigerant from a cooling system, such as an air conditioning system in a vehicle.

  • Patent number: 10551094
    Abstract: An absorber or desorber contains one or more micro-channels that have a 3-D structured heat-exchanging surface and a membrane on the microchannel situated distal to the 3-D structured heat-exchanging surface, where the membrane is permeable to a solvent of a solution employed in the absorber or desorber. The 3-D structured surface promotes mixing of hot and cold solution between the 3-D structured heat-exchanging surface and a vapor-exchanging surface proximal to the membrane. The mixing reduces the differences in concentration and temperature of the bulk solution and the solution at the vapor-exchanging surface to enhance the efficiency and rate of absorption or desorption of the solvent.
