When installing a ceiling cooling fan for cold storage refrigerator ceiling air cooler before installation matters shall be checked

Core clew: 1. In the cold storage cooling fan apart after the outer packing should look for loose parts, such as loose should be retightened; 2. Check the shaft wind flow blades installed on the motor shaft is strong, the wind leaf and protection

1. After cold storage cooling fan apart the outer packing should look for loose parts, such as loose should be retightened;

2. Check the shaft wind flow blades installed on the motor shaft is strong, the wind leaf and guard is touching one another;

3. Such as the cooling fan with damage caused by transportation or deformation, should be repaired before hoisting;

4. Air cooler are nitrogen pressure before they go out, capillary sealing. Before installation to remove the sealing capillary, faintly as LiuSheng said to evaporation air cooler tube sealing is good, can be at ease use. If there is no air said evaporator pipe leaking, should check the installation.


5. Type D condole type air cooler on the rolls of roof bolt assembly, pitch reference cooling fan specifications;

6. Condole type air cooler install and metope distance (fan diameter 400 mm or less than 400 mm) should keep 250-300 mm, the wind so cold air circulating in the cold storage and maintenance;

7. After installation condole type air cooler should guarantee level;

8. Cooling fan of the drain pipe due to the cold storage outside certain slope, the defrosting water be smoothly outbound outside, outside the library of connecting pipe should be dome into U, keep a certain liquid seal, in order to prevent a lot of hot air from outside the library into the cold storage;

9. Outside the drain pipe with insulation in cold storage, library temperature below 20 ℃ condition should be added in order to prevent electric heating tube drainage pipe defrosting water freezes in the drainage process;

10. When installing a expansion valve, temperature sensing package must be tied tightly on the upper level back to the trachea and ensure good contact with the muffler, outside the muffler shall be moisturizing, in order to prevent the heat pack is affected by temperature library;

11. Air cooler exports should avoid open beam or column, lest affect supply range.


12. D freon condole type air cooler electrical wiring box design, in the top left of the cooling fan positive junction box points two types of specifications ㎡ small power less than 22 defrosting terminal electric heating tube, the second specification more than 30 ㎡ cooling fan defrosting the heat pipe type terminal adopts Y connection, due to the three-phase unbalanced load electric heating tube, so the user terminal must be connected to the neutral line, another one thousand have a burn of the overheating of electric heating tube is not in the other two phase electric heat pipe overload;

13. When the defrosting on electric heating tube, fan when the power supply must be disconnected to prevent defrosting blowing hot air into the Treasury;

14. Defrost cycle to adjust for every day and night by frost defrosting 1-4 times, each time the frost time according to the frost thickness frozen to adjust;

15. Defrost apparatus should be delay function, when the end of the defrosting cooling fan fan does not start immediately to prevent the electrical heating tube heat blow into the Treasury, make high temperature heating, affect the rolls items;

16. Regularly check, cleaning the fin dust, ensure that the refrigeration effect.
