Summary:

Tests were conducted with a laminate evaporator for an automotive application. The tests were conducted with HFO-1234yf as the working fluid on an AC system bench. A laminate evaporator from MY 2008 medium-sized sedan was used for this investigation. Flow boiling heat transfer coefficients were experimentally determined for HFO-1234yf for this laminate evaporator. Heat transfer coefficients have also been computed from standard correlations available from the open literature. The experimentally obtained heat transfer coefficients are within ±20% of the simulated data based on standard correlation (Kandlikar, 1990). Pressure gradients for these two fluids calculated from Lockhart and Martinelli (1949) correlation shows that the pressure gradients for HFO-1234yf are lower by 15%. Detailed results have been presented in this paper
