摘要： This refrigeration system is an orifice-tube system constituting a refrigeration cycle in which a refrigerant passes through a compressor 1, a condenser 10, an orifice-tube 3, an evaporator 4, and an accumulator 5 in this order and then returns to the compressor 1. The condenser 10 is constituted by the so-called multi-flow type heat exchanger having a plurality of passes P1-P3. The intermediate pass P2 is constituted as a decompression pass for decompressing the refrigerant. After condensing the refrigerant by the first pass P1, the condensed refrigerant is decompressed and evaporated by the decompression pass P2, and then the evaporated refrigerant is re-condensed by the third pass P3. This refrigeration system is excellent in response characteristic to thermal load fluctuations and in refrigeration performance.

摘要： A fluorescence correlation spectroscopy analyzer 1 is equipped with an excitation light illuminating optical system 21, a fluorescence imaging optical system 22, a CCD camera 15, and a data analyzer 16. The excitation light illuminating optical system 21 illuminates excitation light onto a predetermined region of a measured sample S. The fluorescence imaging optical system 22 images the fluorescence generated at the measured sample S onto the photodetection surface of the CCD camera 15. The CCD camera 15 performs photoelectric conversion of the fluorescence made incident onto the photodetection surface in accordance with the respective pixels and outputs the charges generated by the photoelectric conversion as detection signals from an output terminal. The data analyzer 16 inputs the detection signals based on the charges generated at the pixels, and computes autocorrelation functions of the input detection signals according to each pixel.

摘要： A condenser includes a refrigerant inlet, a refrigerant outlet, a core portion having a refrigerant passage for introducing refrigerant from the refrigerant inlet to the refrigerant outlet while condensing the refrigerant, and decompressing means provided at a part of the refrigerant passage, the decompressing means decompressing a refrigerant pressure. The refrigerant passage located at an upstream side of the decompressing means condensates at least a part of high-pressure gaseous refrigerant into a liquified refrigerant. The decompressing means decompresses the liquified refrigerant into a low-pressure gaseous refrigerant. The refrigerant passage located at a downstream side of the decompressing means re-condensates the low-pressure gaseous refrigerant.
