| Abstract |
The paper gives results of an investigation of the performance of refrigerants R-407C and R-22 with and without a suction line heat exchanger. The cyclic and steady state performances of both refrigerants were investigated in an air conditioner/heat pump. The combined impact of cyclic and steady state performances was evaluated through the cooling and heating seasonal performance, depending on the climate. The steady state tests indicate that there is no benefit from using a suction line heat exchanger for either fluid. However, R-22 and R-407C benefit from the suction line heat exchanger during cycling tests. Utilizing the suction line heat exchanger reduces the performance, degradation associated with cyclic operation by 5.5 and 8.1% for R-22 and R-407C, respectively. |
