Evaporator efficiency issues
The boiling point should be as high as possible to maintain the evaporator efficiency. Using a large evaporator reaches this, but in addition:
- the air cooler, direct expansion fin block must be always free from dirt and slime, and adequately thawed if necessary;
- pipes in shell & tube evaporator must be cleaned in order to prevent fouling and corrosion (water, you may need treatment to reduce such problems);
