Description

Environmental control system Technical Field

[0001] This invention belongs to the field of medical air conditioning, and specifically relates to an environmental control system. Background Technology

[0002] The operation of the power supply and distribution system and its environmental control system in a hospital operating room is crucial to the smooth conduct of surgery and the safety of patients. The "environmental control system" refers to the system that regulates at least the air temperature in the operating room (such as air conditioning).

[0003] The prior art, document CN110425707A, discloses a "multifunctional environmental control system for operating rooms". This technical solution includes a control module, sensor components, a fresh air circulation system, a noise reduction mechanism, and an operating room lighting system. The input terminal of the control module is electrically connected to the output terminal of the data processing module, the input terminal of the data processing module is electrically connected to the output terminal of the data analysis module, the input terminal of the data analysis module is electrically connected to the output terminal of the data storage module, the input terminal of the data storage module is electrically connected to the output terminal of the data receiving module, and the input terminal of the data receiving module is electrically connected to the output terminal of the data acquisition system.

[0004] However, the above-mentioned "multifunctional environmental control system for operating rooms" has the following drawbacks:

[0005] The "Multifunctional Environmental Control System for Operating Rooms" is powered by the operating room's power supply. Like other equipment in the operating room, it is susceptible to unexpected power outages, resulting in the loss of environmental control functions after such an outage. Therefore, this system still cannot meet the needs of emergency power outage scenarios.

[0006] Based on this, the applicant is considering designing an environmental control system that can better meet the needs of emergency power outage scenarios. Summary of the Invention

[0007] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is: how to provide an environmental control system that can better meet the needs of emergency power outage scenarios.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0009] An environmental control system includes a controller, a temperature sensor module, and an air conditioning module for regulating the temperature of the surrounding space, wherein the temperature sensor module and the air conditioning module are each electrically connected to a corresponding interface on the controller; characterized in that:

[0010] It also includes a housing and an uninterruptible power supply, with casters fixedly installed around the bottom of the housing;

[0011] The uninterruptible power supply, controller, sensor module and air conditioning module are fixedly installed on the enclosure. The uninterruptible power supply is used to power the controller, sensor module and air conditioning module.

[0012] Compared with the prior art, the environmental control system of the present invention has the following advantages:

[0013] 1. Easy to transfer and flexible deployment.

[0014] The entire system is mounted on a box with casters at the bottom, making it easy to move the box to the space where it is needed (such as a ward or operating room). This makes the environmental control system easier to deploy quickly and can be reused in multiple spaces that are not used at the same time, thereby helping to reduce the deployment and usage costs in multiple spaces that are not used at the same time.

[0015] 2. Reliable power supply, capable of meeting the needs of emergency power outage scenarios.

[0016] The enclosure is equipped with an uninterruptible power supply (UPS), which can quickly (within milliseconds) switch to the battery pack inside the UPS when external power is lost, thereby meeting the environmental control requirements in emergency power outage scenarios.

[0017] 3. More flexible to use

[0018] The environmental control system involved in this technical solution is more suitable for spaces that require temporary use (such as inflatable modular units) because it is an independent and easily relocatable structure. It is also suitable for supplementing existing hospital operating rooms with installed environmental control devices, improving the reliability of operating room environmental control, better meeting the environmental control needs in extreme power outage scenarios, and improving the reliability of the medical system's treatment environment.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] In practice: as shown in Figures 1 to 7.

[0031] An environmental control system includes a controller, a temperature sensor module, and an air conditioning module for regulating the temperature of the surrounding space. The temperature sensor module and the air conditioning module are each electrically connected to a corresponding interface on the controller.

[0032] It also includes a housing and an uninterruptible power supply, with casters fixedly installed around the bottom of the housing;

[0033] The uninterruptible power supply, controller, sensor module and air conditioning module are fixedly installed on the enclosure. The uninterruptible power supply is used to power the controller, sensor module and air conditioning module.

[0034] Uninterruptible power supplies (UPS) are existing technology. Those skilled in the art should be familiar with UPS systems. A UPS includes a rectifier, filter, battery bank, inverter, charger, and monitor. The working principle of a UPS is as follows: the rectifier and filter convert AC mains power into DC power, which then powers the battery bank via the charger. When the monitor detects a power outage, it automatically and quickly switches to powering the inverter via the battery bank. The inverter then outputs power, ensuring uninterrupted power supply and improving power reliability.

[0035] The environmental control system also includes a space volume measurement unit installed on the enclosure. The space volume measurement unit includes a single-line lidar, which includes a laser emitter, a laser receiver, a signal processing unit, and an electrically controlled rotation mechanism.

[0036] The electrically controlled rotating mechanism is fixedly installed on the top outer side of the housing, and the laser emitter and laser receiver are fixedly installed on the rotating part of the electrically controlled rotating mechanism and are electrically connected to the signal processing unit respectively.

[0037] The output interface of the signal processing unit is electrically connected to the corresponding input interface on the controller via a cable.

[0038] During implementation, the laser emitted by the laser emitter is invisible to the human body. Preferably, the single-line lidar is a KRLIDAR S30 lidar (manufactured by KRLIDAR (Nanjing) Technology Co., Ltd.); or a single-line scanning lidar of the 01A series (manufactured by Shenzhen Guowei Sensing Technology Co., Ltd.).

[0039] In practice, the principle of using single-line lidar to calculate the volume of space is as follows: the length (L) and width (W) of the horizontal plane are measured by single-line lidar, and the height (H) of the space is a default preset value (such as taking the space height as 3 meters according to the operating room design standard); thus, the volume of space V = L × W × H.

[0040] By employing the aforementioned space volume measurement unit, a wider range of air conditioning control modes can be achieved. For example, the volume of the space where the environmental control system is located can be calculated, allowing for comprehensive adjustment of the ambient temperature based on the space volume and the actual detected temperature. Furthermore, by measuring the space volume and adjusting the airflow of the air conditioning module, slow (over 15 minutes), medium (5-15 minutes), and fast (less than 5 minutes) air conditioning can be implemented. In addition, it can better balance and achieve a smooth and comfortable air conditioning rhythm, as well as lower energy consumption, thus extending the operating time of the environmental control system when powered by the battery pack.

[0041] The environmental control system also includes an emergency oxygen generation module mounted on the enclosure. The emergency oxygen generation module includes an oxygen generation shell, a fan, and a fan controller, all fixedly installed inside the enclosure. The oxygen generation shell has a sealed inner cavity, and its outer surface is provided with an inlet and an outlet that are sealed and connected to the sealed inner cavity. The inlet is connected to the atmosphere and used for drawing in air. The outer surface of the enclosure is provided with an emergency oxygen generation output connector that protrudes outward and is sealed and connected to the outlet on its inner side.

[0042] An oxygen-generating lithium-based molecular sieve plate is fixedly installed in the sealed inner cavity between the input and output sides; the fan is used to adsorb and transport the airflow from the input port to the output port.

[0043] The fan controller is electrically connected to the uninterruptible power supply, and the control button of the fan controller is located on the outer surface of the housing.

[0044] In practice, it is preferable to hang an oxygen mask on the outside of the box, and the air inlet of the oxygen mask is sealed to the emergency oxygen output connector through a hose.

[0045] In practice, it is preferable to provide an LED light on the outer side of the housing with the irradiation surface facing downwards and capable of illuminating the oxygen mask.

[0046] After adopting the above emergency oxygen generation module, oxygen can be generated for patients in a timely manner in emergency situations.

[0047] The box is divided by partitions to form an air-conditioning space with an overall L-shaped structure and a heat dissipation space with a column-shaped structure.

[0048] The air conditioning module includes a primary filter and a secondary filter arranged side by side from the outside to the inside in a horizontal channel at the bottom of the air conditioning space. The secondary filter is a medium-efficiency filter or a high-efficiency filter. An air conditioning air intake hole is provided on the housing directly opposite the outer end of the horizontal channel.

[0049] The air conditioning module also includes an air conditioning controller, an air conditioning fan, a cooling fan, and a compressor, evaporator, and condenser connected in a loop via pipes; the air conditioning controller is electrically connected to the controller and the uninterruptible power supply, and the air conditioning controller is electrically connected to the air conditioning fan, the cooling fan, and the compressor;

[0050] The air conditioning fan is fixedly installed at the top of the vertical channel of the air-conditioned space, and the outer side of the housing is provided with an air conditioning outlet that connects to the air outlet of the air conditioning fan; the compressor is fixedly installed at the bottom of the vertical channel of the air-conditioned space; the evaporator is fixedly installed in the space between the primary filter and the secondary filter; the condenser and the cooling fan are fixedly installed in the heat dissipation space, and the top outer side of the housing is provided with a heat dissipation exhaust port that is sealed and connected to the exhaust port of the cooling fan.

[0051] In practice, those skilled in the art should know that in order for the enclosure to be able to move and work smoothly in an indoor space, it should be connected to the heat dissipation and exhaust interface using a flexible or corrugated hose, so that the enclosure can be moved and used smoothly indoors.

[0052] By adopting the above-mentioned cabinet and air conditioning module structure, the cabinet structure can maintain its compact characteristics, while the air conditioning module can make full use of the internal space of the cabinet for layout. Furthermore, the air intake of the air conditioner can be filtered and purified through two-stage filters, which better protects the air quality of the operating room and better ensures the smooth progress of the operation.

[0053] A water receiving tank is also provided at the bottom of the box body. A water hole is vertically provided through the bottom surface of the horizontal channel of the L-shaped structure of the air-conditioned space to communicate with the water receiving tank. A liquid level sensor electrically connected to the controller is provided inside the water receiving tank. A liquid level indication mechanism electrically connected to the controller is provided on the outside of the box body. A drain pipe with a control valve is provided on the outside of the bottom of the box body, which is sealed and connected to the bottom of the water receiving tank.

[0054] The interior of the water tank is configured as a cavity for fixing and installing the battery pack of the uninterruptible power supply, and the battery pack is a waterproof battery pack with an external waterproof casing.

[0055] The above-mentioned water tank design facilitates the collection of condensate. At the same time, the level sensor and level indicator mechanism provide timely information on the water level in the tank, preventing malfunctions caused by excessively high water levels.

[0056] Placing the battery pack inside the water tank not only lowers the overall center of gravity of the enclosure, making it more stable to move, but also allows for water cooling by utilizing the condensate in the tank, which is used as the coolant for the battery pack, thus better ensuring the safety and reliability of the battery pack during long-term operation, since the battery generates heat when charging or providing emergency power.

[0057] In practice, the liquid level indicator mechanism can be a liquid level indicator light or an electronic screen.

[0058] Above the air-conditioned space where the primary filter, evaporator and secondary filter are located is an interlayer space. The partition between the interlayer space and the heat dissipation space is provided with air holes for heat fusion. A sealing limit cover made of engineering plastic material is also fixedly installed in the interlayer space. The sealing limit cover has a pair of downward protruding connecting parts that are sleeved on the upper inner sides of the primary filter and the secondary filter.

[0059] The lower surface between the pair of protruding connecting parts is spaced apart from the top of the evaporator and has a through-hole; an air inlet is fixedly provided on the upper surface of the sealing and limiting cover, and the side wall of the air inlet adjacent to the upper surface of the sealing and limiting cover has a through-hole that communicates laterally with the surrounding outside; the air inlet is sealed and connected to the input port on the oxygen generating shell through a connecting hose.

[0060] In specific implementation, it is preferable that the upper surface of the sealing and limiting cover is provided with multiple reinforcing ribs radiating outwards from the root of the air intake connection nozzle.

[0061] With the above structure, the mezzanine space can form a unique flow channel structure and a unique airflow, specifically:

[0062] The interlayer space is connected to the air-conditioning space between the two filters and above the evaporator through perforations. The interlayer space is connected to the heat dissipation space through a vent for hot and cold fusion. In this way, the vent for hot and cold fusion not only allows a small amount of cold air from the air-conditioning space to enter and achieve better cooling and heat dissipation of the condenser, but also allows a small amount of hot air from the heat dissipation space to enter the interlayer space to heat the air temperature in the interlayer space. This results in the air temperature in the interlayer space being in the range between the air conditioner outlet temperature and the heat dissipation space temperature, which is usually 30-39 degrees Celsius.

[0063] Therefore, by connecting the air inlet of the emergency oxygen generation module to the air outlet in the interlayer space, the temperature of the generated oxygen can be kept at 30-39 degrees Celsius, which makes the oxygen temperature closer to the human body temperature, preventing patients from inhaling cold oxygen and irritating their respiratory tract, thus providing better protection.

[0064] The lower end of the vertical channel of the L-shaped structure of the air-conditioned space has an opening that communicates with the water receiving tank. An ultrasonic atomizing module is fixedly installed inside the water receiving tank directly below the opening, and the ultrasonic atomizing module is electrically connected to the controller.

[0065] Once powered on, the ultrasonic atomizing module can atomize liquid water using its own ultrasonic atomizing sheet. Combined with its positioning, the mist can be quickly blown out along the vertical channel of the L-shaped structure of the air conditioning duct with the airflow, thus simultaneously achieving the functions of temperature regulation and humidification.

[0066] The air outlet of the air conditioning module can rotate horizontally, and the angle between the axis of the air outlet and the horizontal plane is 10 to 40 degrees.

[0067] The air outlet of the air conditioning module not only avoids the feeling of no wind when the air blows directly on the body, but also makes full use of the characteristic that the air conditioning air descends faster after humidification, so that the air conditioning air blown out can descend more quickly from the air above the area where the person is located and change the air environment of the space where the person is located, thus obtaining a better air conditioning effect.

[0068] The temperature sensor includes an external temperature sensor for detecting the ambient temperature of the space where the enclosure is located and a temperature sensor for detecting the air outlet temperature of the air conditioning module on the enclosure.

[0069] The external temperature sensor is a spectral thermal imaging temperature measurement pan-tilt camera that is fixedly installed on the outside of the top of the enclosure;

[0070] The air outlet of the air conditioning module is an electronically controlled rotary air outlet.

[0071] In this way, the location of a human body in the space can be located by a spectral thermal imaging temperature measurement pan-tilt camera, and the location can be transmitted to the controller. The controller can then control the electronically controlled rotating air outlet to precisely regulate the environmental parameters around the human body, thereby achieving a more energy-efficient and effective environmental control effect.

[0072] In practice, the spectral thermal imaging temperature measurement PTZ camera can be an IRS-PT264-T thermal imaging dual-spectrum intelligent lightweight PTZ camera (manufactured by Yantai IRay Optoelectronics Technology Co., Ltd.).

[0073] The above are merely preferred embodiments of the present invention. It should be noted that any modifications and improvements made by those skilled in the art without departing from the present technical solution should also be considered to fall within the scope of protection claimed in this claim.
