The programs are of use for thermodynamic, hydraulic (pressure drops) and dimensions computation of heat exchangers. Other group of the programs are intended for computation the work characteristics of refrigeration machine components. It is not necessary to input thermophysical properties of refrigerant, water, air and several secondary coolants, because they will be calculated in the same programmes.
The programmes have many possibilities: they comprise heat exchangers (condensers and evaporators) with plain and finned tubes, different arrangement of tubes (in_line and in_stagger), many kind of refrigerants and secondary coolants. Ozone friendly refrigerants like R134a, R404A, R407C, R410A and natural refrigerants R290 (Methane) and R717 (Ammonia) are included too.
