An experimental study of a multi-port vapor injected scroll compressor.

Summary
Previous research indicates that a scroll compressor with multiple vapor injection ports has the potential to significantly improve the energy efficiency and heating capacity of vapor compression heat pumps, particularly at low outdoor temperatures. Based on a tradeoff between cost and benefit, a dual-port vapor injected compressor prototype was chosen for testing to provide experimental validation of the efficiency benefits. The overall performance of a heat pump system employing the compressor prototype was analyzed. Coupling the compressor testing results with a three-stage expansion vapor injection flash tank cycle model, the operating injection pressures were determined for different working conditions. The results showed that injection pressures and corresponding injected mass flow rates decreased with an increase of ratio of discharge to suction pressure. Comparing the COP of the vapor injection cycle with a baseline cycle, the improvement in COP increased with an increase of the pressure ratio and was 19% for cold climate heating conditions with an evaporating temperature of -30°C and a condensing temperature of 43.3°C.
