摘要

· Preliminary results from a thermal/flow analysis of the PCPA indicate that the pump performance (mass flow rate) is enhanced via cooling of the housing and lowering of the inlet vapor quality. · Under a nominal operational profile (25% duty cycle or less), atthe maximum motor dissipation, it appears that the peristaltic tubing temperature will still remain significantly below the expected UPA condenser temperature (78°F max versus ~105°F in the condenser) permitting condensation in the pump head.
