Further efficiencies are gained by using a process called Liquid Injection or Superheat Supression. This process de-superheats the compressor discharge temperature by 50K (100F) or more before it enters the condensers. One of many applications to save natural resources is eliminating the build up of scale in water cooled condensers, as the discharge temperature entering the condenser is below the temperature at which scale forms, maintaining peak efficiencies. Other applications are de superheating evaporative condensers to reduce drift loss or water evaporation. Most often these losses contain chemicals which are harmful to the environment Recently, de super-heating Co2 compressor discharge temperatures have found to improve cascade condenser efficiencies and improve compression ratios .
