Energy-saving type closed-type cooling tower refrigerating system applied to IDC machine room

Abstract

The invention discloses an energy-saving type closed-type cooling tower refrigerating system applied to an IDC machine room. The energy-saving type closed-type cooling tower refrigerating system comprises a closed type cooling tower, a solar absorption refrigeration unit, a cold water tank, a chilled water pump, a cooling water pump, an IDC machine room tail end device, a solar heat collector, a first circulation water pump, a heat collecting water tank, a second circulation water pump, an embedded type control system, a solar absorption type refrigeration unit return water temperature sensor, a closed type cooling tower return water temperature sensor, a closed type cooling tower inlet air dry-wet ball temperature sensor, a closed type cooling tower draught fan frequency changer, a closed type cooling tower circulation water pump frequency changer and electrically-operated valves, wherein the embedded type control system, the solar absorption type refrigeration unit return water temperature sensor, the closed type cooling tower return water temperature sensor, the closed type cooling tower inlet air dry-wet ball temperature sensor, the closed type cooling tower draught fan frequency changer, the closed type cooling tower circulation water pump frequency changer and the electrically-operated valves are electrically connected. According to the energy-saving type closed-type cooling tower refrigerating system, the closed type cooling tower working condition running manner is adopted, and the solar absorption refrigeration unit cannot be opened at night in winter, in transition season and in summer; a closed type cooling tower is used for refrigeration, the solar absorption refrigeration unit is used in the day in summer, solar energy is used for refrigeration, energy saving and electricity saving are achieved, and the energy-saving type closed-type cooling tower refrigerating system is safe, reliable and environment-friendly.

Description

technical field [0001] The invention relates to the field of air conditioning of IDC machine rooms, in particular to an energy-saving closed cooling tower refrigeration system applied to IDC machine rooms. Background technique [0002] In the IDC (Internet Data Center, Internet Data Center) computer room, due to the large heat dissipation of the equipment, in order to ensure the normal operation of the equipment, the temperature of the computer room needs to be controlled at 22°C±2°C all year round. The particularity of the IDC computer room is as follows: (1) The cooling load is used throughout the year, so the refrigeration system needs to be turned on throughout the year and run 24 hours a day; Very high; (3) In order to ensure that the IDC computer room can still operate normally in the case of water failure, it is required to be equipped with a water reservoir. [0003] Due to the expansion of the scale of the existing IDC computer room, more and more systems adopt wat...

AI Technical Summary

Problems solved by technology

The air-cooled natural cooling system has the following disadvantages: (1) It is difficult to guarantee the cleanliness of the IDC computer room; (2) It is difficult to control the humidity in the IDC computer room; (3) The air duct is large, the floor area is large, and the cost is high; (4) ) limited use time, limited energy saving effect

However, when the water-cooled unit is turned on during the day in summer, it still needs to consume a lot of electricity
