Abstract
<p>In order to suppress the discharge temperature rise of the scroll compressor at the high compression ratio operation in air conditioning systems, it is necessary to apply the injection for cooling gas refrigerant with liquid or two-phase refrigerant. However, the conventional injection has two problems, the ineffective compression loss due to the dead volume and the pressure pulsation at the injection pipe caused by the pressure propagation from the compression chamber. To solve these problems, we developed the new type of injection “Suction chamber injection” cooling the gas refrigerant before compression. In this paper, we report the features of suction chamber injection and the evaluation results of the prototype. The results are as follows: (1) Discharge temperature can be reduced without diluting oil. (2) The pressure pulsation in the injection pipe can be reduced by 77% compared to the compression chamber injection. (3) Compression efficiency is higher than compression chamber injection by suppressing the ineffective compression loss.</p>
