Air cooled screw chiller Advantages :

1, do not need to occupy a special machine room, and do not need to install cooling tower and pump room, convenient operation, without professional maintenance;

2. Air cooled unit has no cooling water system, saving urban water; (The floating water loss of water cooling tower of water cooling unit is 5‰ per hour)

3. Lower maintenance cost than water cooling unit;

4, energy-saving operation (according to the actual load refrigeration load 12.5% to 100% stepless adjustment)

Disadvantages of air-cooled screw chiller;

1, generally installed in the outdoor, the operation environment is relatively harsh, in the maintenance and reliability are not as convenient as water cooled chiller;

2. The high condensing temperature reduces the operating efficiency of the refrigeration unit;

3. The high temperature refrigeration effect is poor in summer;
