4. For the user and installer the TVP maybe considered as a classical refrigeration system where gas is compressed and cooled to induce condensation to a liquid The liquefied gas is then passed through a metering device orifice causing a pressure drop and subsequent evaporation within a closed volume cryo coil producing a cooling effect The system differs from a conventional system in that it has several different gases and a complex array of heat exchange surfaces are used to achieve the cryogenic temperature required The TVP uses the auto cascade principle which achieves low temperatures in a single compressive step This is different from many other low temperature refrigeration systems which achieve low temperatures by linking together two or more compressive refrigeration steps to form a classical cascade system Further background information on auto cascade systems can be obtained from Telemark i H20 m 2 gt 1 Compressor 2 Condenser 3 Evaporator Diagram 21 Simple refrigeration cycle Page 61 of 61 TVP Manual full March 2007 CE rev 03 doc Low pressure trip Oil return line Return line Service port PT COMP Compressor Oil separator Service port DTI z Discharge line Defrost line Defrost hand Water out Valve ba High ondensor pressure trip Water in a System drier Pi val I I l Heat exchange array I T Cool h
