CHAPTER 3: HEA T PUMP STh1ULATION MODEL 72 All of the above fitted equations are reasonable fittings, 'x' being the common denominator for the discharge pressure. From all of the above generated polynomial equations the mass flow through the system and the compressor efficiency can be described in terms of evaporating pressure and discharge pressure. All the polynomial equations can now be combined into two final equations - one equation describing the mass flow in terms of evaporating pressure and discharge pressure and the other describing the compressor efficiency in terms of evaporating pressure and discharge pressure. The two formulas attained are as follows: m (-2.l646xlO-9 .Pdi/ +4.2438xlO-5 ·Pdi• 2.0742xlO-1)+ • 122 8 (2.3263 xl 0- • P dis 4.7418 x10- • P dis + 2.6913xl0-4)· P suc + 162 11 82 (-5.6907xl0- • PdiS +1.0683X 10- • Pdfs 4.147xl0- ).
