摘要： A method and apparatus for determining the sufficiency of refrigerant charge in an air conditioning system by the use of only two temperature measurements. The temperature of the liquid refrigerant leaving the condenser coil is sensed and the temperature of the condenser coil itself is sensed and the difference between these two measurements is calculated to provide an indication of the adequacy of refrigerant charge in the system. This process is refined by steps taken to eliminate measurements during transient operations and by filtering signals to eliminate undesirable noise. A permitted threshold of deviation is calculated by using probability theory.

摘要： The sufficiency of refrigerant charge in an air conditioning system is determined by a comparison of two sensed temperatures in the system, one being the liquid line temperature and the other being either the outdoor temperature or the condenser coil temperature. In one embodiment the two sensed temperatures are displayed on respective thermochromic strips which are so calibrated and juxtaposed as to provide a visual indication, by the relative positions of the two displayed sensed temperatures, as to whether the refrigerant charge is adequate. In another embodiment, the sensed liquid line temperature is displayed by way of a plurality of LEDs and the other temperature is displayed by way of a marker on a temperature scale. If the two displayed temperatures are aligned, then the refrigerant charge is optimized, and if they are not aligned, the system is undercharged or overcharged.

摘要： A braze-free connector for attaching a flow line to an operating unit of a flow system. The connector has a central passage into which the flow line is inserted through a tapered entranceway. The entranceway opens into a radially expanded cavity that surrounds a section of the flow line. The cavity is filled with a pressure activated adhesive. A ferrule is mounted in the entranceway and is rotatably mounted upon a threaded nut which mates with a male thread on the connector body. As the nut is advanced, the ferrule moves axially into the cavity to activate the adhesive, and at the same time, is forced radially into tight sealing contact with the flow line.
