Description

Technical Field

[0001] This utility model relates to the field of air conditioning, specifically a satellite communication cabinet-type split-row air conditioner. Background Technology

[0002] In existing high-precision electronics fields, such as communication cabinets, air conditioning is required for heat dissipation. Existing in-row air conditioners are installed as a whole unit between the cabinet rows to dissipate the heat from the entire row. This large-scale heat exchange results in high overall energy consumption for the air conditioner. Ordinary large-area heat dissipation cannot meet the heat dissipation needs of electronic devices that generate a lot of heat, which can easily affect the performance and lifespan of the device. Summary of the Invention

[0003] This invention provides a simple structure for a satellite communication cabinet split-type in-row air conditioner that can balance efficient heat dissipation and energy consumption control.

[0004] The technical solution adopted by this utility model is: a split-type inter-row air conditioner for satellite communication cabinets, comprising two or more compression refrigeration systems, characterized in that: the compression refrigeration system includes a compressor, first and second air-cooled condensers, a condensing pressure sensor, a filter, a liquid receiver, an electronic expansion valve, an evaporator, an evaporating fan, and a pressure transmitter; the compressor exhaust sequentially passes through the first and second air-cooled condensers, the condensing pressure sensor, the filter, the liquid receiver, the electronic expansion valve, the evaporator, and the pressure transmitter before returning to the compressor; the evaporator is equipped with an evaporating fan; the first air-cooled condensers of the two or more compression refrigeration systems correspond to and share a first condensing fan, and the second air-cooled condensers of the two or more compression refrigeration systems correspond to and share a second condensing fan.

[0005] The two or more sets of compression refrigeration systems are set up in different electronic cabinet rows.

[0006] A split-type in-row air conditioner for satellite communication cabinets includes two or more compression refrigeration systems, characterized in that: the compression refrigeration system includes a compressor, three or more air-cooled condensers, a condensing pressure sensor, a filter, a liquid receiver, an electronic expansion valve, an evaporator, an evaporating fan, and a pressure transmitter; the compressor exhaust sequentially passes through three or more air-cooled condensers, a condensing pressure sensor, a filter, a liquid receiver, an electronic expansion valve, an evaporator, and a pressure transmitter before returning to the compressor; each evaporator is equipped with an evaporating fan; the three or more air-cooled condensers in the two or more compression refrigeration systems are all one-to-one and share a single condensing fan.

[0007] The compressor's exhaust and return air are both connected via vibration-damping hoses.

[0008] The compressor exhaust end is connected to a high / low pressure switch.

[0009] The compressor exhaust end is connected to an oil separator, and the liquid phase of the oil separator is reversed and connected to the compressor return gas end via a valve.

[0010] The two or more compression refrigeration systems share a common air-cooled condenser, and the condenser has multiple condensation processes connected to multiple compression refrigeration systems.

[0011] The beneficial effects of this utility model are:

[0012] 1. Multiple compression refrigeration systems are adopted to address the different heat dissipation needs of different rows within the cabinet or the different heat generation of different electronic devices in the same row. This can meet the targeted cooling and heat dissipation needs of electronic devices in the cabinet, effectively avoiding the high energy consumption and low cooling problems of large-area or single-row overall heat dissipation, ensuring efficient heat dissipation of high-precision electronic devices, while also taking into account cooling energy consumption.

[0013] 2. Each compression refrigeration system employs two or more air-cooled condensers combined with condensing pressure sensors, which can effectively control the condensing pressure and meet the high-precision refrigeration requirements of the evaporator. Simultaneously, it ensures continued operation of the air conditioner even if any air-cooled condenser fails, improving system stability.

[0014] 3. Multiple air-cooled condensers of different compression refrigeration systems share a single condenser fan. The evaporator and evaporator fan of the compression refrigeration system closest to the condenser fan are placed in the row with the highest heat generation or in the part of the same row with the highest heat generation. The evaporator and evaporator fan of the compression refrigeration system furthest from the condenser fan are placed in the row with the lowest heat generation or in the part of the same row with the lowest heat generation. This helps with energy consumption control and targeted, high-precision heat dissipation control. Attached Figure Description

[0017] The following explanation, in conjunction with the accompanying drawings, will provide further details.

[0018] Figure 1The illustrated embodiment provides a split-type in-row air conditioner for satellite communication cabinets, comprising three sets of compression refrigeration systems. Each compression refrigeration system includes a compressor 1. The exhaust gas from compressor 1 passes sequentially through a vibration-damping hose 2, a high / low pressure switch 3, a needle valve 4, an oil separator 5, a check valve 7, a first air-cooled condenser 8, a second air-cooled condenser 9, a condensing pressure sensor 12, a filter 13, a liquid receiver 14, an electronic expansion valve 15, an evaporator 16, a pressure transmitter 18, a needle valve, and a vibration-damping hose to the compressor return gas. The first air-cooled condensers 8 of the three compression refrigeration systems are arranged sequentially, corresponding to the first condensing fan 10, and the second air-cooled condensers 9 of the three compression refrigeration systems are arranged sequentially, corresponding to the second condensing fan 11. In this embodiment, the evaporator and evaporating fan of the compression refrigeration system containing the air-cooled condenser closest to the condensing fan are located at the location of the highest heat generation or the row with the highest heat output.

[0019] In this embodiment, the liquid phase of the oil separator 5 is returned to the compressor return gas end via a needle-type fluorine ball valve 6.

[0020] Based on this embodiment, multiple air-cooled condensers corresponding to one-to-one compression refrigeration systems can share a single condenser, with multiple condensation processes connected to multiple compression refrigeration systems within the condenser.
