Figure 1

What is Vapour Injection?

  • As shown in Figure1, the liquid out of the condenser is separated into two parts. A smaller part of the liquid is expanded through an additional expansion valve, and then flows into a counter-flow plate heat exchanger (HX).
  • The main part of the liquid out of the condenser, is then cooled down through the economizer while evaporating and superheating the injection mass flow.
  • This additional plate heat exchanger, more generally called economizer, acts therefore as a subcooler for the main mass flow and as an evaporator for the injection mass flow.
  • Superheated vapour is then injected into the intermediate vapour injection port in the scroll compressor.

Copeland ZFI Scroll Compressor Condensing Unit Diagram

  • Emerson Copeland ZFI scroll compressor requires a a plate heat exchanger as an subcooler, generally called economizier.
  • The vapor injection refrigeration cycle offers the advantages of more cooling delivered and a better COP than with a conventional cycle.
  • The cooling provided by vapor injection allows the operation of the compressor over a larger envelop compared with a conventional single-stage model, providing higher cooling capacity at low evaporating temperatures.
