Description
Technical Field
[0001] This utility model belongs to the field of aviation electromechanical systems and relates to a refrigeration component with a water filter device. Background Technology
[0002] The refrigeration unit is the core refrigeration unit of an aircraft's air conditioning system. It processes the high-temperature, high-pressure gas introduced into the bleed air system, ensuring that the gas pressure, temperature, and humidity reach the specified states. Furthermore, the refrigeration unit also dehumidifies the bleed air, removing free water from the system. The water vapor mixture discharged from the refrigeration unit's water separator drain nozzle can reduce the airflow supplied to the cabin and cockpit. Simultaneously, particulate impurities in the water vapor mixture can easily clog water supply pipes and atomizing nozzles, severely reducing the refrigeration unit's cooling efficiency. Utility Model Content
[0003] To address the aforementioned issues, this invention provides a refrigeration assembly with a water filter device, which effectively prevents blockage of the water supply pipe and atomizing nozzle structure, thus ensuring the refrigeration effect of the refrigeration assembly.
[0004] The technical solution of this utility model is as follows: A refrigeration assembly with a water filter includes a first heat exchanger, a second heat exchanger, an air circulator, a condenser, a water separator, and a water filter. The first and second heat exchangers are located in an engine nacelle. The first heat exchanger is connected to an air intake inlet, and its outlet is connected to the compressor inlet of the air circulator. The compressor outlet of the air circulator is connected to the inlet of the second heat exchanger, and its outlet is connected to the first inlet of the condenser. The first outlet of the condenser is connected to the inlet of the water separator, the air outlet of the water separator is connected to the turbine inlet of the air circulator, the turbine outlet of the air circulator is connected to the second inlet of the condenser, and the water outlet of the water separator is connected to the inlet of the water filter.
[0005] Furthermore, the second outlet of the condenser supplies air to the aircraft's air conditioning system; wherein the first inlet of the condenser is connected to the first outlet but not to the second outlet, the second inlet of the condenser is connected to the second outlet but not to the first outlet, and the channel between the first inlet and the first outlet of the condenser and the channel between the second inlet and the second outlet exchange heat with each other.
[0006] Furthermore, the outlet of the water filter is located inside the engine nacelle.
[0007] Furthermore, the outlet of the water filter is equipped with an atomizing nozzle, which is directed toward the first heat exchanger and the second heat exchanger.
[0008] Furthermore, the fan section of the air circulator is located inside the engine nacelle.
[0009] Furthermore, within the engine nacelle, along the airflow from upstream to downstream, an air circulator, a water filter outlet, a second heat exchanger, and a first heat exchanger are sequentially arranged.
[0010] The beneficial effects of this utility model are as follows: This utility model provides a design for a refrigeration component with a water filter device. The water filter has a structure that impedes the fluid and separates impurities, filtering the water-vapor mixture discharged from the drain nozzle of the water separator. This effectively ensures that the atomizing nozzle will not become clogged. At the same time, the resistance loss of the water filter can effectively slow down the flow rate of the water-vapor mixture, reduce the air leakage loss of the refrigeration component, and reduce the adverse effects caused by air leakage in small-flow air conditioning refrigeration components.

[0016] Example 1: A refrigeration assembly with a water filter includes a first heat exchanger, a second heat exchanger, an air circulator (ACM), a condenser (CON), a water separator (WE), and a water filter (FIL). The first and second heat exchangers are located within an engine nacelle. The first heat exchanger is connected to an air intake inlet. The outlet of the first heat exchanger is connected to the compressor inlet of the air circulator (ACM). The compressor outlet of the air circulator (ACM) is connected to the inlet of the second heat exchanger. The outlet of the second heat exchanger is connected to the first inlet of the condenser (CON). The first outlet of the condenser (CON) is connected to the inlet of the water separator (WE). The air outlet of the water separator (WE) is connected to the turbine inlet of the air circulator (ACM). The turbine outlet of the air circulator (ACM) is connected to the second inlet of the condenser (CON). The water outlet of the water separator (WE) is connected to the inlet of the water filter (FIL).
[0017] The second outlet of the condenser CON supplies air to the aircraft's air conditioning system; wherein the first inlet of the condenser CON is connected to the first outlet but not to the second outlet, the second inlet of the condenser CON is connected to the second outlet but not to the first outlet, and the channel between the first inlet and the first outlet of the condenser CON and the channel between the second inlet and the second outlet exchange heat with each other.
[0018] The outlet of the water filter (FIL) is located inside the engine nacelle.
[0019] The outlet of the water filter FIL is equipped with an atomizing nozzle WS, which faces the first heat exchanger and the second heat exchanger.
[0020] The fan section of the air circulator (ACM) is located inside the engine nacelle.
[0021] Inside the engine nacelle, along the airflow from upstream to downstream, the air circulator (ACM), the outlet of the water filter (FIL), the second heat exchanger, and the first heat exchanger are installed in sequence.
[0022] Example 2: See Figure 1This application provides a refrigeration component design with a water filter device, including a heat exchanger, an air circulator, a condenser, a water separator, a water filter, and an atomizing nozzle.
[0023] The refrigeration components adopt a three-wheel high-pressure dehydration air circulation system configuration.
[0024] The high-temperature, high-pressure air drawn out by the induced draft system is first cooled in the first heat exchanger, and then pressurized and heated, expanded and cooled in the air circulator (ACM) to perform work.
[0025] The refrigeration system also includes a condenser CON, which condenses most of the water vapor in the hot air cooled by the heat exchanger into free water. It also includes a water separator WE, which separates the free water condensed in the system, thereby improving the performance of the refrigeration system.
[0026] The main structural material of each product in the refrigeration component is aluminum alloy.
[0027] The various components of the refrigeration system are connected via air ducts, clamps, etc.
[0028] When the refrigeration unit is in operation, the air cooled by the second heat exchanger enters the condenser, where further cooling produces more free water. Subsequently, the gas carrying a large amount of free water enters the water separator to separate the free water. The separated free water passes through the drain nozzle and then enters the water filter FIL. After impurities are filtered in the water filter, the separated free water enters the atomizing nozzle WS, where it is atomized.
[0029] See Figure 2 The water filter device structure provided in this application includes a base 1, a filter screen 2, a sealing ring 3, a frame 4, an end cap 5, and a housing 6, wherein: It should be noted that the water filter consists of a housing and a filter element, which includes a base, filter screen, frame, end caps and sealing rings.
[0030] It should be noted that the frame is the support structure for the filter screen and is divided into upper and lower parts.
[0031] The shell material is 06Cr19Ni10 stainless steel, and the surface treatment is passivation.
[0032] The base is made of aluminum alloy 2A12-T4, and the surface treatment is colorless anodizing.
[0033] When the water filter is in use, the fluid enters the water filter from the housing 6. After the fluid is split at the end cap 5, it passes through the filter screen 2 to filter impurities, and then flows to the next stage through the base 1 channel.
[0034] In summary, this application provides a refrigeration component design with a water filter device, including a heat exchanger 1 for heat exchange, an air circulator 2 for pressurization and heating, expansion and cooling and external work, a condensation mixing chamber 3 for condensing free water and exchanging heat, a water separator 4 for separating free water, a water filter 5 for reducing leakage and filtering impurities, and an atomizing nozzle 6 for atomizing free water. The design employs a barrier structure and filter cartridge filtration method to filter impurities in the free water separated by the water separator and reduce air leakage caused by drainage.
