Large-power UPS (uninterrupted power supply) special air-conditioner battery cabinet and method for adjusting and controlling working temperature of storage battery

Abstract

The invention discloses a large-power UPS (uninterrupted power supply) special air-conditioner battery cabinet and a method for adjusting and controlling the working temperature of a storage battery, aiming at solving the problems of refrigeration when the mains power is abnormal and the storage battery discharges to generate a large amount of heat and high energy consumption of the precise air conditioner of the existing storage battery room. The large-power UPS special air-conditioner battery cabinet comprises a phase-change air conditioner and a constant-temperature battery box, wherein the phase-change air conditioner comprises a phase-change material box, a heat exchanger and a control box, and also comprises a fan, an air duct and an evaporator in the constant-temperature battery box; the phase-change material box is filled with a phase-change material and is provided with fin tubes, another evaporator and a temperature sensor; the control box is connected with the phase-change material box and is internally provided with a water pump, a condenser, a controller, a compressor and an uninterrupted power supply. The large-power UPS special air-conditioner battery cabinet and the method for adjusting and controlling the working temperature of the storage battery disclosed by the invention are applicable to protection of storage batteries in a large-power UPS in a machine room and have the advantages that the temperature in the constant-temperature battery box can be still controlled in the optimum working temperature of the storage batteries with large refrigerating capacity and long time after the power fails, the reliability of the storage batteries is improved, the service life of the storage batteries is prolonged, the purposes of energy conservation and environmental protection are achieved and the reliability is high.

Description

technical field [0001] The invention relates to the field of air-conditioning equipment, in particular to a special air-conditioning battery cabinet for high-power UPS and a method for regulating and controlling the working temperature of the storage battery. Background technique [0002] Large and medium-sized data centers and communication equipment rooms usually have more server equipment. In order to ensure the normal operation of the server equipment after a power failure, it is usually necessary to configure a high-power UPS and a large number of batteries for the UPS. When the mains power is normal, the battery configured by the high-power UPS stores electric energy through chemical reactions. At this time, the battery is in a floating charge state with little heat generation; when the mains power is abnormal, the battery releases the stored energy through chemical reactions to supply power for server equipment , to ensure the uninterrupted operation of the server equ...

Problems solved by technology

[0003] In order to overcome the abnormality of the mains power, the cooling problem when the battery discharges a large amount of heat, and the lack of high energy consumption of the existing precision air conditioner in the battery room, to achieve the purpose of controlling the working temperature of the battery for a long time and with a large cooling capacity, according to the battery in the mains When it is normal, it is in the state of floating charge, and the calorific value is small. When the commercial power is abnormal, it is in the discharge state, and the calorific value is extremely large. Under normal conditions, the cooling capacity is stored by the phase change material in the phase change air conditioner. When the mains power is abnormal, the stored cooling capacity is released. Regardless of whether the mains power is normal or not, the temperature of the battery can be controlled at the optimum temperature of 20°C-25°C. Within the working temperature range, this solution uses the compressor to cool the phase change material to store the cooling capacity. The cooling capacity is large and the cooling time is long. Reliability of the battery, prolonging the service life of the battery, and at the same time, the temperature of the machine room can be raised to 35°C, which can significantly save the energy consumption of the precision air conditioner in the machine room
