Abstract
This paper has investigated the PT equation of state for the new environmental-friendly refrigerant R600a, and on this basis, the mathematical model of heat pump with regenerator internal heat exchanger is constructed. After systematical calculating and analyzing the cycle performance of the heat pump charged with R600a and several types under standard operating condition and variable operating conditions, the results show that the coefficient of performance charged with R600a is better than R22, thus R600a can be regarded as a promising alternative of refrigerant heat pump.
