Remarks:1. The cooling capacity in the table calibration conditions: chilled water inlet temperature +12 ℃, water temperature +7 ℃, evaporation temperature +2 ℃, condensing temperature +40 ℃, cooling water inlet temperature +30 ℃, the export temperature of +35 ℃ to derive; 2. When the outside ambient temperature is lower than +2 ℃ or long-term not in use, you should drain the machine of water to prevent the copper tube frost expansion; 3. Specification and performance will be due to the product improvement has changed.No notice.
