Experimental and Numerical Testing of Heat Pump Evaporator

When designing a heat pump evaporator, it is necessary to use correlations that ensure small deviations of the designed and realized process parameters for specific input data. The aim work propose suitable mathematical model physical in tubular evaporator pump. applicability proposed design was evaluated by comparing results obtained from experimental tests with numerical application model. For tests, made 10 measuring points were set up, where measured (temperature pressure drop working media R134a water). Theoretical dividing into control volumes solving corresponding system equations using Runge-Kutta Adams Moulton predictor-corrector method. As an independent parameter, water temperature at inlet varied range °C 18 °C. test show largest deviation calculated +0.41 −0.58 °C, while refrigerant +0.43 + 0.52 thermal capacity based on calculations +9.39% −6.31%. Based results, possible recommend
