Description

Technical Field

[0001] This utility model belongs to the field of air conditioning system technology, specifically relating to a combined refrigerant pump air conditioning unit that simultaneously produces cold air and cold water. Background Technology

[0002] With the rapid development of technology, especially in the fields of high-performance computing and electronic devices, the power density of components is gradually increasing, leading to a significant increase in heat load. This growing demand has prompted the development of more efficient cooling technologies, particularly in critical applications such as servers, supercomputers, electric vehicles, and 5G communication equipment.

[0003] Traditional air-cooling technology relies on ambient air for heat dissipation, making its efficiency limited by ambient temperature. In compact or enclosed spaces, air-cooling struggles to handle high heat output. While liquid cooling can offer higher heat dissipation efficiency, it incurs higher initial investment and maintenance costs, involving complex piping and pumping systems.

[0004] Traditional mechanical refrigeration systems use energy-intensive components such as compressors and condensers. Because they cannot fully utilize natural cooling sources, these systems consume a considerable amount of electricity throughout the year, making it difficult to achieve high energy efficiency. Furthermore, mechanical refrigeration systems also face problems such as high maintenance costs and high noise levels, which increases the difficulty of managing and maintaining data centers.

[0097] (1) When in winter

[0098] exist Figure 3 and Figure 4 In the unit shown, compressor 9 and surface cooler I7 are turned off. When compressor 9 stops running, bypass valve I29 is closed and bypass valve II30 is opened to realize the refrigerant pump circulation.

[0100] (2) During the transition season

[0101] exist Figure 5 In the unit shown, compressor 9 and surface cooler I7 are turned off. When compressor 9 stops running, bypass valve I29 is closed and bypass valve II30 is opened to realize refrigerant pump circulation. Evaporator 3 and wet film 4 in the refrigerant pump circulation can be used to cool the air input through exhaust duct 38. Adjustable air valve 13 can be opened to control the ratio of fresh air and return air. After mixing, the air passes through wet film 4 and evaporator 3 in sequence for cooling, and then the fan I2 delivers air to the data center through air supply duct 37.

[0102] Air enters the chiller unit's surface cooler 54 through the fresh air inlet 11 for pre-cooling, and then enters the direct evaporative cooling chiller unit I 46 to produce chilled water through the direct evaporative cooling principle. The produced chilled water is pressurized by water pump II 20 and transported to the water distribution unit III 23. Outside air exits the direct evaporative cooling chiller unit I 46 and then enters the direct evaporative cooling chiller unit II 47 to produce chilled water again. The chilled water is then transported to the CDU module 28 and the chiller unit's surface cooler 54 through water pump III 21. Finally, the outside air is discharged outdoors through the exhaust vent 26.

[0103] (3) During the summer

[0104] exist Figure 6 In the unit shown, the refrigerant pump 12 and valve II 30 are turned off. When the compressor 9 is running, the bypass valve I 29 is opened and the bypass valve II 30 is closed to realize the mechanical refrigeration system. The evaporator 3 and wet film 4 in the refrigerant pump cycle can be used to cool the air input through the exhaust duct 38. The adjustable air valve 13 is closed to prevent fresh air from entering. The return air passes through the surface cooler I 7, wet film 4 and evaporator 3 in sequence to be cooled, and then the fan I 2 delivers air to the data center through the air supply duct 37.

[0105] Meanwhile, other work processes are the same as those during the transition season. Finally, the direct evaporative cooling chiller unit II 47 produces chilled water and delivers it to the CDU module 28, chiller surface cooler 54, and surface cooler I 7 via water pump III 21.
