Feature and Benefits

Copeland ZSI Compressor Condensing Unit

Emerson ZSI Compressor for walk in cooler condensing unit

Liquid injection & CoreSense

Copeland ZSI scroll compressor liquid injection controlled by the CoreSense control board, can regulates liquid injection by sensing the discharge line temperature (DLT). This technology not only widens the operating envelop, but also enhances the reliability of the Copeland walk in cooler condensing unit.

Wide evaporating temperature

Wide evaporating temperature range from -30°C to 0°C. The Copeland scroll compressor condensing units perfectly fits medium temperature application and also low temperature application.

High efficiency & energy saving

The COP improvement of ZSI scroll compressor makes the outdoor condensing unit annual electrical savings of 10%–30% or about $100–$500 per year.

High reliability

Emerson Copeland scroll compressor has fewer parts compared to traditional piston compressors, thus making the commercial  condensing unit more reliable.

ZSI Scroll Compressor walk in cooler condensing unit Refrigeration System Diagram

ZSI Scroll Compressor Refrigeration System Diagram

  • ZSI scroll compressor requires a liquid injection circuit from the system’s liquid line to the compressor’s injection fitting.
  • The liquid injection is controlled by Coresense control board. It can regulates the liquid injection by sensing the discharge line temperature (DLT).
  • DLT sensor is discharge line temperature sensor. The function of the DLT sensor is to determine the degree of the expansion valve, thus ensuring proper injection flow rate.
  • EXV is a expansion valve. The function of expansion valve is to remove the pressure from the liquid refrigerant to allow expansion or change of state from a liquid refrigerant to a vapor refrigerant.
Liquid injection technology of ZSI compressor walk in cooler condensing unit

What’s the Functions and Advantages of Liquid Injection of ZSI Scroll Compressors?

  • The function of liquid injection is to protect the compressor from high discharge temperature failure and improve the compressor reliability in low temperature condition.
  • An Injection EXV must be applied when using the ZSI scrolls for liquid injection operation. This valve is approved for all refrigerants in this product range.
  • Liquid injection ZSI scroll compressor has extremely enhanced reliability compared to non-injection scroll compressors at low temp application.
CoreSense of ZSI Scroll Compressor

What is the CoreSense of ZSI Scroll Compressor?

  • CoreSense is a control module or control board. It controls the amount of the liquid injection by measuring the discharge temperature by an DLT sensor mounted on the discharge pipe.
  • The CoreSense can automatically calculates the expansion valve’s opening and commands it to inject the optimized amount of liquid refrigerant into the compressor.
