摘要： A method and apparatus for determining the sufficiency of refrigerant charge in an air conditioning system using a single temperature sensor for sensing three different temperatures within the system to compute a condenser approach temperature difference, which in then compared with a predetermined optimal condenser approach temperature difference to indicate the charge condition of the system. The device includes an absorbent pad for sensing wet bulb temperatures, and is formed as a clamshell that can be clamped onto the condenser liquid line. A microprocessor is included to make the comparison and to appropriately display the result as a visual indication of charge adequacy.

摘要： A method and apparatus for determining the sufficiency of the refrigerant charge in an air conditioning system by use of temperature measurements. The temperature of the liquid refrigerant leaving the condenser coil and the outdoor temperature are sensed and representative electrical signals are generated. The electrical signals are converted to digital values that are than compared to predetermined optimal values to determine whether the system is properly charged with refrigerant. An appropriate LED is lighted to indicate that the system is undercharged, overcharged or properly charged. For non-TXV/EXV systems a third parameter i.e. the return air wet bulb temperature is also sensed and a representative digital value thereof is included in the comparison with the predetermined known values to determine if the charge is proper.

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.
摘要翻译：空调系统中制冷剂充注的充足性取决于系统中两个感测温度的比较，一个是液体管线温度，另一个是室外温度或冷凝器盘管温度。在一个实施例中，两个感测到的温度显示在相应的热变色条上，这些条带被如此校准并且并置，以通过两个显示的感测温度的相对位置提供关于制冷剂充注量是否足够的可视指示。在另一个实施例中，通过多个LED显示感测到的液体线温度，另一个温度通过温度标度的标记来显示。如果两个显示的温度对齐，则制冷剂充量被优化，如果它们不对准，则系统的充电不足或过充电。

摘要： An air conditioning system includes a plurality of sensors for sensing temperature and/or pressure conditions of the system which collectively indicate the actual refrigerant charge level in the system. This level is then compared with optimum level values that are stored in memory, and the difference between the two is used to indicate whether the system is properly charged. If not, the difference is applied to open a charge valve or a purge valve to automatically install additional refrigerant or to remove refrigerant so as to establish an optimum volume of refrigerant in the system.

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： A braze-free connector for joining a pair of flow lines in leak tight manner. The connector has a tubular body with entranceways at each end face of the body that converge inwardly and open into the central passage of the body. A flow line is inserted into the body through each entranceway so that the lines meet in abutting contact at about the midsection of the body. A collapsible metal ferrule surrounds each of the lines and is at least partially housed within each entranceway. Members having internal threads that are mated with external threads on the body are arranged to advance the ferrules into the entranceway whereupon the ferrules are forces radially into metal to metal sealing contact with the tubes by the converging wall surfaces of the entranceways.
