Description

Technical Field

[0001] This invention relates to the field of container environmental control systems, and particularly to a container with a distributed environmental control system. Background Technology

[0002] As military equipment becomes increasingly integrated, mobile shelters not only perform functions such as equipment control, intelligence processing, and reporting, but also provide space for the installation of electronic equipment. Therefore, the environmental control system of the mobile shelter must simultaneously address the environmental control issues for personnel and the heat dissipation issues for electronic equipment.

[0003] Military container air conditioning systems are widely used in container environmental control systems. Under low-heat conditions, these systems can simultaneously meet the needs of personnel environmental control and electronic equipment cooling. However, with the increasing heat consumption of electronic equipment within the container, these air conditioning systems are increasingly unable to meet the new demands of electronic equipment containers. The performance parameters of military container air conditioning systems are based on the design specifications of comfort air conditioners, characterized by low airflow, large temperature differences, and the ability to only heat but not cool in low-temperature conditions. In contrast, electronic equipment requires high airflow, small enthalpy differences, and cooling across the entire temperature range. The airflow provided by military container air conditioning systems is significantly less than the cooling requirements of electronic equipment, and the lack of cooling functionality in low-temperature conditions prevents heat from being dissipated to the external environment, often leading to new problems such as overheating of electronic equipment. Summary of the Invention

[0004] Purpose of the invention: The purpose of this invention is to provide a container with a distributed environmental control system that can meet the heat dissipation requirements of electronic equipment and has scalability, while also taking into account the environmental control requirements of personnel.

[0005] Technical solution: The container with a distributed environmental control system according to the present invention includes a container body, which is divided into a personnel operation room and an equipment room by a partition wall. An air duct is provided on the top of the container body along the axial direction of the container body, which runs through the operation room and the equipment room. The air inlet of the air duct is connected to an environmental control fan coil unit installed on the top of the equipment room, and the air return outlet of the air duct is located on the top of the partition wall and communicates with the operation room.

[0006] The equipment cabinets in the equipment room are equipped with plug-in cooling fan coil units, which together with the heat sinks of the electronic equipment in the equipment cabinets form a closed-loop air-cooling heat dissipation system.

[0007] A liquid cooling source is installed on the outer wall of the cabin where the equipment room is located. The liquid cooling source adopts a modular design and includes a liquid supply control unit and a cooling and heat dissipation unit. The two are connected by pipes and cables. The liquid cooling source provides low-temperature coolant to the environmental control fan coil and the cooling fan coil through an environmental control liquid cooling pipe network, and dissipates the heat carried by the coolant into the atmospheric environment outside the cabin.

[0008] Preferably, the partition wall is equipped with a sliding door that facilitates personnel access to the operating room and equipment room. The partition wall and the sliding door adopt a sandwich design that combines honeycomb aluminum and thermal insulation cotton structure.

[0009] Preferably, the environmental control fan coil unit is configured with three operating conditions based on the difference between the detected return air temperature and the set temperature: cooling condition, heating condition, and ventilation condition.

[0010] When the environmental control fan coil unit is in cooling mode, once the fan starts, based on the difference between the return air temperature detected by the return air temperature sensor and the set temperature, the opening of the proportional regulating valve is automatically adjusted through the program set by the control module to control the flow rate of coolant entering the air-cooled radiator of the environmental control fan coil unit, thereby regulating the cooling capacity and ensuring that the difference between the return air temperature and the set value is within the design range.

[0011] When the environmental control fan coil unit is in heating mode, once the fan starts, the electric heating is turned on, the passage of coolant into the air-cooled radiator through the proportional regulating valve is completely closed, and all coolant is bypassed back to the liquid cooling source.

[0012] When the environmental control fan coil unit is in ventilation mode, once the fan is turned on, the passage for coolant to enter the air-cooled radiator through the proportional regulating valve is completely closed, and all coolant is bypassed back to the liquid cooling source.

[0013] Preferably, the cooling fan coil unit compares the return air temperature detected by the return air temperature sensor with the set value, and automatically adjusts the opening of the proportional regulating valve to control the flow rate of coolant entering the air-cooled radiator of the cooling fan coil unit, thereby regulating the cooling energy and ensuring that the difference between the return air temperature and the set value is within the design range. This avoids the condensation problem caused by the excessively low supply air temperature under low heat consumption conditions of the equipment cabinet.

[0014] Preferably, the environmentally controlled liquid cooling pipeline is equipped with insulation equipment to prevent condensation caused by low pipeline temperature.

[0015] Preferably, the liquid cooling source simultaneously supplies coolant to the environmental control fan coil unit and the cooling fan coil unit in each equipment cabinet. The environmental control fan coil unit and the cooling fan coil unit automatically adjust the coolant flow rate through their respective air-cooled radiators according to their respective return air set temperatures, thereby achieving adaptive adjustment of the heat dissipation of the environmental control fan coil unit and the cooling fan coil unit.

[0016] Preferably, the refrigeration and heat dissipation unit includes a compression refrigeration system, a radiator, a second fan, and a solenoid valve. The compression refrigeration system includes a compressor, a condenser, an evaporator, and a throttling valve. The radiator and condenser share the same fan. The refrigeration and heat dissipation unit automatically switches between a high-temperature operating mode and a normal-temperature operating mode based on the ambient temperature and the liquid supply temperature.

[0017] Preferably, in the high-temperature operating mode, the refrigeration and heat dissipation unit operates in compression refrigeration mode. The solenoid valve switches the flow of high-temperature coolant to the evaporator. When the coolant flows through the evaporator, it transfers heat to the Freon, and the coolant temperature decreases. When the Freon passes through the compressor and transfers the heat it carries to the condenser, the heat is dissipated into the atmosphere through heat exchange between the fan and the condenser.

[0018] Preferably, in the normal temperature operating mode, the solenoid valve switches the flow of high-temperature coolant to the radiator, and the heat is dissipated into the atmosphere through heat exchange between the fan and the radiator.

[0019] Preferably, the liquid supply control unit includes a liquid supply module and a control module;

[0020] The liquid supply module includes a liquid supply pump, an expansion tank, an electric heating element, and a liquid replenishment tank. The liquid supply pump provides clean coolant with stable pressure and flow rate to the environmental control fan coil unit and the cooling fan coil unit.

[0021] The control module includes high-voltage components that control the operation of the fan, liquid supply pump, compressor, and electric heater, as well as low-voltage equipment that detects flow rate, pressure, temperature, and differential pressure sensors. It controls the start and stop of the fan, liquid supply pump, compressor, and electric heater within the liquid cooling source, and completes the monitoring of operating parameters and the uploading of fault information.

[0022] Beneficial effects:

[0023] (1) The sandwich design of the partition wall in this application plays a role in sound insulation and heat insulation, reducing the impact of the heat and noise of the equipment in the equipment room on the personnel operating room.

[0024] (2) The cooling fan coil units in this application are flexibly arranged in a distributed manner according to the number and layout of the equipment cabinets, and have the characteristics of strong modularity and easy expansion.

[0025] (3) In this application, the cooling fan coil and the electronic equipment heat sink form a closed-loop air supply and heat dissipation in the equipment cabinet; this air supply method close to the heat source improves the uniformity of the air supply temperature in the cabinet, shortens the air supply distance, reduces the energy consumption of the transmission, and the cleanliness of the circulating air is easy to ensure, thus improving the reliability of the electronic equipment.

[0026] (4) In this application, the cooling fan coil unit automatically adjusts the heat dissipation according to the return air temperature, and the heat dissipation of the cooling fan coil unit is adaptively matched with the heat of electronic equipment, thereby reducing operating energy consumption.

[0027] (5) In this application, cooling fan coil units and environmental control fan coil units with different parameters and performance can be set according to the different heat dissipation needs of operators and electronic equipment, so as to realize the environmental control function of operators and the heat dissipation function of electronic equipment.

[0028] (6) The liquid cooling source in this application adopts a combination design of high-temperature compression refrigeration and low-temperature conventional heat dissipation, so that heat dissipation function can be realized in the entire temperature range.

[0029] (7) In this application, the cabin environmental control function and the electronic equipment heat dissipation function share the liquid cooling source as the final heat dissipation device, and at the same time provide the environmental control fan coil and the cooling fan coil with the same low temperature coolant, which simplifies the amount of external environmental control equipment and makes the environmental control system more integrated.

[0037] The present invention will be further described clearly and completely below with reference to specific embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit this application.

[0038] like Figure 1-3 The diagram shows the layout of the mobile cabin environmental control system of the present invention. In this embodiment, the system includes a mobile cabin 1, which is divided into a personnel operating room 2 and an equipment room 3 by a partition wall 10. A duct 7 is provided on the top of the mobile cabin 1 along the axial direction of the mobile cabin 1, which connects the operating room 2 and the equipment room 3. The air inlet of the duct 7 is connected to the environmental control fan coil unit 6 located on the top of the equipment room 3. The environmental control fan coil unit 6 delivers air radially toward the mobile cabin 1 through the duct 7. The return air outlet of the duct 7 is located on the top of the partition wall 10 and communicates with the operating room 2.

[0039] In this embodiment, the cooling fan coil unit 11 inside the equipment cabinet 4 is installed in the equipment cabinet 4 as a plug-in, and at the same time, it is connected in parallel to provide closed-loop air circulation control for several electronic devices 12 inside the equipment cabinet 4.

[0040] In this embodiment, the liquid cooling source 5 is installed near the outer wall of the equipment room 3. It adopts a modular design and is divided into two parts: a liquid supply control module 9 and a cooling and heat dissipation module 8, which are interconnected by pipes and cables. The liquid cooling source 5 provides low-temperature coolant to the environmentally controlled fan coil unit 6 and each cooling fan coil unit 11 in the equipment cabinet 4 through an environmentally controlled liquid cooling pipe network including a liquid supply pipe 13 and a liquid return pipe 14. Insulation equipment is installed on the outer wall of the environmentally controlled liquid cooling pipe network to prevent condensation caused by low temperature in the pipes.

[0041] In this embodiment, the partition wall 10 is provided with a sliding door to facilitate personnel to enter and exit the operating room 2 and the equipment room 3. The partition wall 10 and the sliding door adopt a sandwich design that combines honeycomb aluminum and thermal insulation cotton structure.

[0042] like Figure 3-4The diagram shows the layout of the cooling fan coil unit and electronic equipment, as well as the internal structure of the cooling fan coil unit. The cooling fan coil unit 11 inside the equipment cabinet 4 provides cooling air for heat exchange with the air-cooled radiator of the electronic equipment 12, transferring heat from the electronic equipment to the circulating cooling air, thus increasing the air temperature. The high-temperature cooling air is then drawn back into the cooling fan coil unit 11 by the fan 15, where it exchanges heat with the coolant in the liquid-cooled radiator 16, transferring heat to the coolant, increasing the coolant temperature, and decreasing the cooling air temperature, thus continuously circulating. A return air temperature sensor 19 and a humidity sensor 20 are installed at the return air inlet of the cooling fan coil unit 11, and a proportional regulating valve 17 is installed between the supply pipe 13 and the return pipe 14. The control board 18 compares the return air temperature detected by the return air temperature sensor 19 with the set temperature and adjusts the opening of the proportional regulating valve 17 to regulate the flow rate of coolant entering the liquid-cooled radiator 16, thereby achieving automatic adjustment of the heat dissipation of the cooling fan coil unit 11 inside the equipment cabinet 4. The cooling fan coil units 11 in the equipment cabinet 4 are all connected in parallel to supply air to each electronic device 12. The supply air temperature is the same, and there is no problem of heat accumulation due to series air supply.

[0043] like Figure 5 The diagram shows the internal structure of the environmental control fan coil unit. The environmental control fan coil unit has three operating modes: cooling mode, heating mode, and ventilation mode. When the environmental control fan coil unit is in cooling mode: fan 23 is turned on, and the air temperature rises after heat exchange with the environment and personnel in the control room 2. The high-temperature air is then drawn back into the environmental control fan coil unit 6 by fan 23, where it exchanges heat with the coolant in the air-cooled radiator 21, transferring heat to the coolant. The coolant temperature rises, and the air temperature decreases, thus continuously cycling. A supply air temperature sensor 25 and a supply air pressure sensor 26 are installed at the air outlet of the environmental control fan coil unit 6 to monitor the supply air temperature and supply air pressure of the environmental control fan coil unit 6, respectively. A return air temperature sensor 46 and a humidity sensor 47 are installed at the return air inlet of the environmental control fan coil unit 6. A proportional regulating valve 17 is installed between the liquid supply pipe 13 and the liquid return pipe 14. The control board 24 compares the return air temperature detected by the return air temperature sensor 46 with the set temperature and adjusts the opening of the proportional regulating valve 17 to regulate the flow rate of coolant entering the liquid-cooled radiator 21, thereby realizing the automatic adjustment of the cooling capacity of the environmental control fan coil unit 6.

[0044] When the environmental control fan coil unit 6 is in heating mode: Fan 1 23 is turned on, and the control board 24 starts the electric heater 22 in groups according to the difference between the return air temperature detected by the return air temperature sensor 2 46 and the set value; the proportional regulating valve 17 adjusts the coolant so that it does not pass through the air-cooled radiator 21, and all of it flows back to the liquid cooling source 5.

[0045] When the environmental control fan coil unit 6 is in ventilation mode: fan 23 is turned on, and the proportional regulating valve 17 regulates the coolant so that it does not pass through the air-cooled radiator 21, but flows back to the liquid cooling source 5.

[0046] like Figure 6 The diagram shows the internal structure of the liquid cooling source. The high-temperature coolant carried by the fan coil unit 6 and the cooling fan coil unit 12 in the equipment cabinet 4 returns to the supply module of the liquid supply control unit 8 in the liquid cooling source 5 via the return pipe 14. A return pressure sensor 37, a return temperature sensor 38, and a flow sensor 39 are installed on the return pipe to detect the return pressure, temperature, and flow rate of the coolant, respectively. Then, the coolant passes through the pipe heater 40, which heats the coolant under low-temperature conditions, reducing its viscosity and facilitating the low-temperature start-up of the supply pump 43. Finally, the coolant passes through the expansion tank 41 and the replenishment tank 42. The expansion tank 41 functions to adjust the coolant temperature when the ambient temperature changes. This provides stable pressure for the closed-loop coolant circulation system; the replenishment tank 42 automatically replenishes coolant when it is low; then, after being sucked in by the supply pump 43, the supply pressure increases, providing resistance to the flow of coolant on the coolant side of the evaporator 30, condenser 28, supply pipe 13, return pipe 14, environmental control fan coil 6, and cooling fan coil 11; after being pressurized, the coolant enters the refrigeration unit 9, and based on the coolant temperature detected by the supply temperature sensor 35, the ambient temperature detected by the ambient temperature sensor 44, and their respective set values, it automatically selects whether to switch the solenoid valve 32 to the conventional heat exchange path or the compression refrigeration path.

[0047] After entering the conventional heat exchange path, the refrigeration and heat dissipation unit switches to the normal temperature working mode. At this time, the coolant enters the conventional radiator 27 and transfers heat to the air through forced convection heat exchange between the fan 2 33 and the conventional radiator 27. The coolant temperature decreases and passes through the filter 34 to filter out system impurities. Then, the coolant temperature and pressure information at the outlet are detected by the supply temperature sensor 35 and the supply pressure sensor 36, and it is sent again to the environmental control fan coil unit 6 and the cooling fan coil unit 11 of each equipment cabinet 4.

[0048] After entering the compression refrigeration circuit, the refrigeration and heat dissipation unit switches to high-temperature operating mode. At this time, the high-temperature coolant enters the evaporator 30 and exchanges heat with the refrigerant side in the evaporator 30, transferring heat to the refrigerant. After the coolant temperature decreases, it flows through the filter 34, the liquid supply temperature sensor 35, and the liquid supply pressure sensor 36, and enters the environmental control fan coil unit 6 and the cooling fan coil units 11 in each equipment cabinet 4. The refrigerant absorbs heat from the coolant in the evaporator 30 and evaporates into gas. It is then drawn into the compressor 29 and compressed into a high-temperature, high-pressure gas, which enters the condenser 28. Through forced convection heat exchange between the fan 23 and the condenser 28, the heat of the refrigerant is transferred to the air, and the refrigerant forms a low-temperature, high-pressure liquid. After passing through the throttling valve 31, it becomes a low-temperature, low-pressure liquid and is evaporated again in the evaporator 30, completing the refrigerant system cycle.

[0049] The liquid cooling source 5 has heat dissipation function in both high-temperature and normal-temperature operating modes.

[0050] The control box 45 in the control module of the liquid supply control unit contains high-voltage control equipment for controlling the start and stop of the liquid supply pump 43, the second fan 33 and the compressor 29; and collects status information from the liquid supply temperature sensor 38, the liquid supply pressure sensor 36, the return liquid temperature sensor 35, the return liquid pressure sensor 37, the flow sensor 39, etc., and uploads it through network communication.
