[0024] Embodiment 1 like Figure 1 As shown, the present invention provides a variable temperature air supply ceiling system for an operating room, including a different temperature air supply purification air conditioning unit, the different temperature air supply purification air conditioning unit is connected to the air supply laminar ceiling through a supply and return air duct module, the different temperature air supply purification air conditioning unit, the supply and return air duct system and the air supply laminar ceiling are all electrically connected to an intelligent control module located in the operating room, and the working states of other modules can be automatically and reasonably adjusted through the intelligent control module. The intelligent control module includes a temperature sensor, a humidity sensor and a cleanliness sensor arranged in the operating room, and detects the environmental data in the operating room in real time. Each sensor transmits the collected data to the main control unit for signal processing, and the main control unit includes a temperature adjustment subunit and a level adjustment subunit, which respectively make corresponding active controls according to the preset control strategy and the received environmental data. Since the intelligent control modules all adopt the relatively mature existing technologies, no more details will be given here.

[0025] In this embodiment, a return air inlet 26 and a fresh air inlet 21 are respectively provided on the air inlet side of the differential temperature air supply and purification air-conditioning unit. The return air inlet 26 inputs circulating air into the interior of the differential temperature air supply and purification air-conditioning unit through the return air duct module, and the fresh air inlet 21 blows fresh air from the outside into the interior of the differential temperature air supply and purification air-conditioning unit to ensure that fresh air always flows into the operating room.

[0026] The interior of the temperature-controlled air supply and purification air conditioning unit is provided with a medium-efficiency filter 9, a hot and cold water coil 8, a deep dehumidification evaporator 10 and a deep dehumidification condenser 7 in sequence along the airflow direction, which are used to adjust the temperature and humidity of the air entering the operating room. A humidification nozzle 5 is installed behind the deep dehumidification condenser. If the air temperature is relatively dry, the humidity of the air can be increased through the humidification nozzle 5. A sterilization lamp is also installed inside the temperature-controlled air supply and purification air conditioning unit, which can effectively eliminate the germs in the air and ensure the cleanliness of the air input into the operating room.

[0027] A main air outlet 27 and a secondary air outlet 28 are respectively provided on the air outlet side of the different-temperature air supply and purification air conditioning unit. Both the main air outlet 27 and the secondary air outlet 28 are connected to the supply and return air duct module, and each forms a path connected to the air supply laminar flow ceiling.

[0028] Among them, a first electric reheater 6 is installed at the main air outlet 27, and a second electric reheater 11 is installed at the secondary air outlet 28, both of which are used to reheat the air to ensure that the temperature of the air entering the operating room can reach a preset value.

[0029] The air supply laminar ceiling includes a middle laminar hood 18 located in the middle and two side laminar hoods 17 located on both sides, which are used to blow air into the operating room respectively, so that the air can enter more evenly. The air supply and return duct module includes a middle laminar hood air supply duct 3, two side laminar hood air supply ducts 2, a return air duct 12 and an exhaust duct 25. Among them, the air inlet side of the middle laminar hood air supply duct 3 is connected to the main air outlet 27, and the air outlet side is connected to the middle laminar hood 18.

[0030] The air inlet side of the laminar flow hood air supply duct 2 on both sides is connected to the secondary air outlet 28, and the air outlet side is connected to the laminar flow hoods 17 on both sides. The laminar flow hood air supply duct 2 on both sides is provided with a first electric valve 4 and a constant air volume valve 1 for controlling the on-off state of the laminar flow hood air supply duct 2 on both sides.

[0031] The air inlet side of the return air duct 12 is connected to the return air ports 24 respectively arranged on both sides of the operating room, and the air outlet side is connected to the return air inlet 26, which is used to input part of the circulating air into the different temperature air supply purification air conditioning unit for recycling, which is beneficial to ensure the temperature and humidity, and is also beneficial to saving energy and improving resource utilization. Figure 1As shown, in this embodiment, five return air ports 24 are respectively arranged on the left and right sides of the operating room, and the left return air ports 24 are alternately installed with left electric valves 15, and the right return air ports 24 are alternately installed with right electric valves 16, which are used to adjust the return air rate of the return air duct 12. The return air duct 12 connected to the left return air ports 24 is installed with a second electric valve 13, and the return air duct 12 connected to the right return air ports 24 is installed with a third electric valve 14, which is used to control the on-off state of the corresponding return air duct 12, thereby adjusting the return air volume.

[0032] The air inlet side of the exhaust duct 25 is connected to the first exhaust port 20 arranged on the top of the operating room, and the air outlet side is connected to the second exhaust port 23, which is used to discharge part of the air in the operating room to the outside. Among them, a silent exhaust fan 22 is arranged on the exhaust duct 25, which can effectively accelerate the exhaust of air and is used to adjust the exhaust rate.

[0033] In use, the operating conditions of the air supply ceiling system in this embodiment can be divided into five-level (hundred-level) operating conditions and seven-level (ten thousand-level) operating conditions, as follows: Level 5 (100) operating conditions: 8100m³ / h of return air in the operating room is mixed with 900m³ / h of treated fresh air through the return air duct 12, totaling 9000m³ / h, and is processed by the medium efficiency filter 9, the hot and cold water coil 8, and the deep dehumidification evaporator 10. A part of the air (3700m³ / h) is sent from the secondary air outlet 28 through the second electric reheater 11, the first electric valve 4, the constant air volume valve 1 and the laminar flow hood air supply duct 2 on both sides to the laminar flow hood 17 on both sides; the other part of the air (5300m³ / h) is sent through the deep dehumidification condenser 7 and the first An electric reheater 6 is sent from the main air outlet 27 to the intermediate laminar hood 18 through the intermediate laminar hood air supply duct 3. The two parts of air can control the temperature according to the specific personnel and actual conditions. After the 9000m³ / h mixed air processes the heat of the operating room, 8100m³ / h returns to the different temperature air supply purification air conditioning unit through 10 return air outlets 24 and the return air duct 12, 500m³ / h is discharged to the outside through the exhaust outlet 20, the exhaust duct 25, the silent exhaust fan 22 and the second exhaust outlet 23, and 400m³ / h remains in the operating room as positive pressure air. In this way, the first air purification process of the five-level (hundred-level) operating room is completed.

[0034] During the switching process between the fifth-level (hundred-level) operating room and the seventh-level (ten thousand-level) operating room, the first electric valve 4 is closed by adjusting the intelligent control module, and the laminar flow hood air supply ducts 2 on both sides are closed. The left electric valve 15 and the right electric valve 16 are closed to close part of the return air outlet, and the variable frequency adjustment air volume of the temperature-differential air supply purification air conditioning unit becomes 3000m³ / h to complete the switching between the fifth-level (hundred-level) and the seventh-level (ten thousand-level) operating room.

[0035] Level 7 (10,000) operating conditions: 2100m³ / h return air in the operating room is mixed with 900m³ / h treated fresh air through the return air duct 12, totaling 3000m³ / h, and then processed through the medium efficiency filter 9, hot and cold water coil 8, and deep dehumidification evaporator 10. The 3000m³ / h mixed air is sent to the intermediate laminar flow hood 18 through the main air outlet 27 through the intermediate laminar flow hood air supply duct 3 through the deep dehumidification condenser 7 and the first electric reheater 6. After the 3000m³ / h mixed air processes the heat of the operating room, 2100m³ / h is returned to the different temperature air supply purification air conditioning unit through the four return air outlets 24 and the return air duct 12. 500m³ / h is discharged to the outside through the exhaust outlet 20, the exhaust duct 25, the silent exhaust fan 22, and the second exhaust outlet 23. 400m³ / h is left in the operating room as positive pressure wind. This completes the first air purification process of the level 7 (10,000) operating room.

[0036] Therefore, the present invention adopts the above-mentioned variable temperature air supply ceiling system for an operating room, which can realize the zoned temperature control and variable adjustment of the cleanliness level of an operating room, improve the air supply effect and air quality, and help improve the adaptability and flexibility of the system.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
