Usually, a refrigeration system is set up in the computer room to achieve the effect of efficient heat dissipation, ensure the normal temperature of various electronic devices in the computer room, and extend the service life of the computer room and electronic devices.
[0004] Traditional computer room refrigeration systems have many limitations in meeting the current requirements of computer rooms. On the one hand, the degree of intelligence of traditional refrigeration systems is relatively low, and it is difficult to dynamically adjust the refrigeration output according to the actual heat load of the computer room, often resulting in energy waste or insufficient refrigeration. On the other hand, there are deficiencies in the design of key components such as oil separators in traditional refrigeration systems. For example, the number of molecular sieves in the oil separator is small and the diameter is small, which easily leads to incomplete oil separation, and then causes problems such as compressor oil carry-over. At the same time, the design of the oil drain port is unreasonable, with a small diameter and a large number, which easily causes poor oil discharge, increases the pressure of the oil drain pipe, and leads to problems such as cracking, oil leakage, and refrigerant leakage of the oil drain pipe, seriously affecting the normal operation of the computer room, and even causing production reduction and shutdown phenomena.

[0021] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0022] Example: Please refer to the attached Figure 1 - Attachment Figure 3 An embodiment of the present invention provides an uninterrupted refrigeration system for a computer room, including a refrigeration module, which cools the interior of the computer room to achieve the effect of cooling and dissipating heat. The refrigeration module includes a compressor module, which inhales low-temperature and low-pressure refrigerant superheated steam from an evaporator, and compresses it into high-temperature and high-pressure superheated steam, providing power for the entire refrigeration cycle, and transports the compressed high-temperature and high-pressure superheated steam to a condenser module. An oil separator module is connected to the compressor module. When the compressor module transmits to the condenser module, it needs to pass through the oil separator module, and the oil separator module is provided with 5 groups of molecular sieves, and the diameter thereof is changed from DN1000 to 1100, which slows down the flow rate and effectively solves the problem of oil leakage in the compressor. At the same time, the oil separator lower oil port was changed from the original three DN80 diameter oil ports to two DN200 diameter oil ports, and the structure was strengthened, with the wall thickness changed from 10 mm to 16 mm, effectively solving the problems of cracking, oil leakage, and fluorine leakage of the oil separator lower oil pipe, and eliminating the production reduction and shutdown caused by cracking and leakage of the oil separator lower oil pipe. The gas treated by the oil separator is then transported to the condenser module.
[0023] The oil separator module is connected to a condenser module, which receives high-temperature and high-pressure superheated steam from the compressor module, cools and condenses the superheated steam into a supercooled liquid through a cooling medium, releases heat, and transmits the supercooled liquid to the throttle valve module. The condenser module is connected to a throttle valve module, which throttles, cools, and reduces the pressure of the supercooled liquid delivered by the condenser module to convert it into low-temperature and low-pressure wet steam, and delivers the low-temperature and low-pressure wet steam to the evaporator module. The throttle valve module is connected to an evaporator module, which receives the low-temperature and low-pressure wet steam delivered by the throttle valve, evaporates and absorbs heat in the evaporator, reduces the temperature of the medium flowing through the evaporator, and simultaneously converts the completely vaporized refrigerant into low-temperature and low-pressure superheated steam, which is then delivered to the compressor to complete the refrigeration cycle. The evaporator module is connected to the compressor module.
[0024] The specific model of the evaporator module is: HZ7A480, and the process media are ethylene glycol, R507A, and refrigeration oil.
[0025] The refrigeration module is connected to a control system module. The control system module monitors the temperature in the machine room and the pressure parameters of the refrigeration system in real time, analyzes and calculates according to a preset algorithm, and controls the operating states of various devices to ensure the stable and efficient operation of the system. The control system module includes a sensor module. The sensor module includes temperature sensors, which are used to monitor the temperature parameters in the machine room in real time and transmit the collected temperature to the control module. There are multiple groups of temperature sensors to achieve the effect of measuring the temperatures at different positions in the machine room. The sensor module is connected to a control module. The control module is composed of a microprocessor, a memory, and an input / output interface. It receives data from the sensor module, and according to the preset control strategy and the calculation results of the algorithm module, issues control instructions to adjust the operating state of the refrigeration system. The specific control strategies include When the temperature sensors detect that the temperature in the machine room is too high, the control module will calculate according to the algorithm the need to increase the power of the compressor or adjust the opening of the throttle valve, and send control instructions to the corresponding devices; When the temperature sensors detect that the temperature in the machine room is normal, the control module maintains the current operating state of the refrigeration system without making large adjustments. Continuously monitor the temperature change. If there are slight fluctuations in the temperature, fine-tuning can be performed to maintain stability When the temperature sensors detect that the temperature in the machine room is too low, the control module will reduce the power of the compressor and the circulation volume of the refrigerant to reduce the refrigeration effect. At the same time, it is necessary to appropriately reduce the opening of the throttle valve to further reduce the refrigerant flow rate into the evaporator The control module is connected to a communication module. The communication module transmits the operating state information of the refrigeration system to the staff's mobile phones. At the same time, the communication module also receives instructions sent by the remote monitoring system to achieve remote control of the refrigeration system. The control module is connected to an algorithm module. The algorithm module provides optimized control strategies for the control module through precise calculation and dynamic adjustment.
[0026] The algorithm module includes a temperature monitoring and prediction algorithm module. The temperature monitoring and prediction algorithm module is responsible for monitoring the temperature in the machine room in real time, collecting temperature data at different positions through multiple temperature sensors to obtain comprehensive and accurate temperature information of the machine room, and based on historical temperature data and the current temperature change trend, using specific calculation formulas for temperature prediction to anticipate the future temperature changes in the machine room in advance; The calculation formula is: Where: : represents the average temperature in the computer room; , : respectively represent the temperature values measured by n different temperature sensors in the computer room; The temperature monitoring and prediction algorithm module is connected to the refrigeration load calculation algorithm module. The key of the refrigeration load calculation algorithm module is to calculate the current refrigeration load of the computer room, considering multiple factors including the power, heat dissipation characteristics of the equipment in the computer room and environmental factors. As the operating state of the equipment and environmental conditions in the computer room change, the calculation result of the refrigeration load is updated in real time using the calculation formula to ensure that the refrigeration system is adjusted according to the actual demand; The calculation formula is: Where: : represents the predicted temperature value; : represents the currently actually measured temperature value; : represents the previously predicted temperature value; : smoothing coefficient, The value of determines the degree of emphasis on the currently actually measured temperature in the prediction. The larger, the closer the prediction result is to the currently actually measured temperature, and the more sensitive the response to temperature changes. While The smaller, the more the prediction result depends on the previous prediction value, and the relatively more stable the response to temperature changes.
[0027] Considering that it is difficult for a single module to comprehensively and accurately adjust the system parameters: when there is only a temperature monitoring module, although the refrigeration system is adjusted according to the temperature change, the impact of changes in the operating state of the equipment on the refrigeration demand cannot be fully considered. Similarly, relying solely on the refrigeration load calculation module may not be able to respond promptly to sudden temperature changes; Through the combined setting of the temperature monitoring and prediction algorithm module and the refrigeration load calculation algorithm module, more comprehensive and accurate information is provided for the control system, enabling the system to adjust the operating parameters more intelligently. For example, when the temperature monitoring module predicts a temperature rise and the refrigeration load calculation module also shows an increase in the current refrigeration load, the system needs to be more decisive in increasing the refrigeration output to ensure the stability of the computer room temperature and the normal operation of the equipment; A system parameter adjustment module is connected to the refrigeration load calculation algorithm module. The refrigeration load calculation algorithm module sends the conclusion to the system parameter adjustment module for reference and selection of corresponding solutions. The temperature monitoring and prediction algorithm module is connected to the system parameter adjustment module. The temperature monitoring and prediction algorithm module sends the conclusion to the system parameter adjustment module for reference, enabling the system parameter adjustment module to comprehensively consider various factors such as temperature changes and equipment performance for judgment, improving the accuracy and effectiveness of the adjustment solution. The system parameter adjustment module is connected to the control module. The system parameter adjustment module draws a conclusion based on various data and sends the conclusion to the control module.
