Condenser side application: 1 cooling tower water cooling condensate 2 sea water, river water or well water cooling condensate 3 ethylene glycol cooling condensate 4 short circuit refrigeration unit system 5 underground water cooling / heat source system 6 heat recovery system condensate side heat exchanger can play the following roles: to protect the condenser from pollution Scaling and corrosion can replace the condenser to bear the side pressure of cooling water, can not operate the refrigeration unit when the season permits, can realize heat recovery, save expensive additives, cooling tower water, cooling condensate Application of evaporation side: 1 pressure relay system 2 separation of cooling circulating water (no pressure relay function) 3 ice storage system 4 area cooling system 5 ceiling cooling system evaporator side heat exchanger can play the following roles: avoid The refrigeration unit bears high pressure (pressure relay system) to reduce the consumption of expensive and inefficient additives and separate the cooling water system to ensure high cleanliness of local system (production of electronic components) and reduce the damage caused by leakage
