  • Apparatus and method for evaluating the performance of a heat exchanger
    Patent number: 4479727
    Abstract: A method and apparatus for evaluting the performance of a heat exchanger are described. Water is supplied to the heat exchanger at a known mass flow rate and temperature. The water is directed to traverse a flow path of the heat exchanger. The water is then heated and redirected into another flow path of the heat exchanger in heat exchange relation with the first flow path. The temperature change of the water over a flow path is measured to determine the performance of the heat exchange. The water flow rate and incoming water temperature may be fixed to make a single discharge temperature measurement sufficient to calculate heat exchager performance.

  • Expansion device with adjustable refrigerant throttling
    Patent number: 4263787
    Abstract: An expansion device having a piston sliding between first and second positions within a valve body. In the first position the piston meters refrigerant flow therethrough and in the second position the piston allows refrigerant to flow unrestricted through the device. Means are disclosed for adjusting the throttling of the refrigerant through the device when it is acting as an expansion device.
