Functional Characteristics of the Refrigerant Circuit
 Depending on operating condition, the refrigerant compressor 1 compresses the vaporous refrigerant from the
inlet pressure of approximately 210kPa (=2,1bar) to the condensation pressure of 800-1700kPa (=8-17bar).
 The vaporous refrigerant is liquefied by cooling in the subsequent refrigerant condenser 2. The fluid refrigerant
is passed through the refrigerant dryer 2 to the flue damper 4.
 The fluid refrigerant is expanded by the flue damper 4 from high pressure (condensation pressure) 1100kPa to
low pressure (evaporation pressure) 210kPa. This expanded and fluid refrigerant flows through the heat-
exchanger pipes 6 of the evaporator 5. By energy input of the exchangeable heat-exchanger 7 the fluid
refrigerant evaporates and cools down the passed through sample gas to a temperature of +3°C. Over the liquid
separator 10 the refrigerant compressor 1 sucks again the vaporous refrigerant.
 Over the power regulator 9 the sample gas conditioner performs a self-adjustment to alternating gas flows,
inlet temperatures and dew points. With a by-pass from the pressure- to the suction-site the pressure-controlled
power regulator 9 keeps the sample gas chilling temperature constant to +3°C.
 The temperature control unit 12 monitors the dew point temperature and accesses the power regulation. It
provides an alarm at unacceptable exceeding or undercut of temperature.
