Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning equipment, and particularly relates to an integrated equipment for fresh air purification of multi-parameter air conditioners for residential use. Background Art

[0002] At present, most residences in China are in the form of apartments, with an average living area of about 120 m² per household. Indoor environmental control mainly relies on air conditioning systems. Common air conditioning forms include split units, multi-connected units, small water chillers, etc. The indoor temperature and humidity are controlled by the operation of air conditioning equipment, and the indoor air quality is adjusted by using fresh air units.

[0003] Generally, split units can only control the indoor heating and cooling environment, and the indoor air quality is poor, which does not meet the requirements of a "good house" for health and comfort.

[0004] For other common household central air conditioning systems, the form of indoor fan coil units + fresh air units is mostly adopted. Two sets of equipment need to be installed to separately handle the indoor temperature and humidity and air quality. The equipment cost is high, the system pipelines are numerous and the structure is complex, the maintenance is troublesome, the coordination is poor, and the comprehensive requirements of comfort and energy saving cannot be achieved simultaneously. Summary of the Invention

[0005] In view of the above technical problems existing in the existing air conditioning forms, the purpose of the present invention is to provide an integrated equipment for fresh air purification of multi-parameter air conditioners for residential use. In this solution, the functions of air conditioning, fresh air and purification are integrated into one equipment, and a switchable air flow channel is provided inside, which can adjust the air flow path according to the monitoring data and energy saving requirements.

[0006] To achieve the above purpose, the integrated equipment for fresh air purification of multi-parameter air conditioners for residential use provided by the present invention includes a housing and a fresh air module, a supply air module, an exhaust air module, a return air module and a control module arranged inside the housing. The housing internally defines a fresh air cavity, a return air cavity and a supply air cavity. The fresh air module is used to introduce outdoor fresh air into the supply air cavity through the fresh air cavity. The return air module is used to introduce indoor air into the supply air cavity through the return air cavity. The supply air module is used to send the gas in the supply air cavity to the indoor space.

[0007] The fresh air cavity and the supply air cavity are connected through a first valve. The fresh air cavity and the return air cavity are connected through a second valve. A third valve is arranged between the return air cavity and the supply air cavity.

[0008] A particulate matter purification module is arranged in the fresh air cavity on one side of the first valve. When the gas enters the supply air cavity through the first valve, it can be processed by the particulate matter purification module.

[0009] The fresh air cavity is provided with a fresh air quality sensor capable of collecting fresh air PM2.5 concentration data, and the return air cavity is provided with a return air quality sensor capable of collecting indoor air PM2.5 concentration data.

[0010] The discharge module is used to discharge the air in the housing and the odor air in the toilet to the outside. The control module can collect indoor environmental parameters and control the fresh air module, the air supply module, the exhaust module, and the return air module based on the collected data.

[0011] The control module sets a PM2.5 concentration threshold internally and processes the data detected by the fresh air quality sensor and the return air quality sensor through edge computing. The control module is configured to compare the threshold with the PM2.5 values of the fresh / return air monitored by the fresh air quality sensor and the return air quality sensor and form corresponding control signals based on the comparison results to control the opening and closing of the first valve, the second valve, and the third valve accordingly, so as to dynamically switch the air flow paths of outdoor fresh air and indoor return air leading to the air supply cavity.

[0012] Further, when the PM2.5 value monitored by the fresh air quality sensor is lower than the set threshold and the return air quality sensor is higher than the set threshold, the control module forms a fresh air purifying return air signal, the control module controls the first valve to close, the second valve to open, and the third valve to open. The fresh air enters the return air cavity through the second valve to dilute the return air in the return air cavity, and they jointly enter the air supply cavity through the third valve.

[0013] When the PM2.5 value monitored by the fresh air quality sensor is higher than the set threshold and the value of the return air quality sensor is lower than the set threshold, the control module forms a fresh air purifying signal and controls the first valve to open, the second valve to close, and the third valve to open. The outdoor fresh air is purified by the particulate matter purification module and then enters the air supply cavity through the first valve, and the return air enters the air supply cavity directly through the third valve without purification.

[0014] When the PM2.5 values monitored by the fresh air quality sensor and the return air quality sensor are both higher than the set threshold, the control module forms a fresh air and return air purifying signal and controls both the first valve and the second valve to open, and the third valve to close. The indoor air enters the fresh air cavity through the second valve, so that both the outdoor fresh air and the indoor air are purified by the particulate matter purification module and then enter the air supply cavity through the first valve.

[0015] When the PM2.5 values monitored by the fresh air quality sensor and the return air quality sensor are both lower than the set threshold, the control module forms a signal indicating no need for purification and controls the first valve to close, the second valve to open, and the third valve to open. The fresh air directly enters the return air cavity through the second valve and mixes with the return air and they jointly enter the air supply cavity through the third valve.

[0016] Furthermore, a fresh air placement bin for placing a fresh air module and a blowing air placement bin for placing a blowing air module are provided inside the housing;

[0017] A fresh air cavity is defined inside the fresh air placement bin, and a placement space for the blowing air module is defined inside the blowing air placement bin. A third valve is connected between the fresh air placement bin and the blowing air placement bin. The third valve divides the internal cavity of the housing into a blowing air cavity and a return air cavity.

[0018] Furthermore, the fresh air module includes a fresh air regulating valve. The fresh air regulating valve is arranged in the fresh air cavity, located at one end of the fresh air placement bin and communicated with the outside. The fresh air regulating valve is used to introduce outside fresh air into the fresh air cavity. A first valve is provided at the other end of the fresh air placement bin. The first valve is communicated with the blowing air cavity. A second valve is provided between the fresh air regulating valve and the first valve in the fresh air cavity. The second valve is communicated with the return air cavity. A fresh air quality sensor and a dehumidification / auxiliary heating and cooling module are sequentially arranged between the fresh air regulating valve and the second valve in the fresh air cavity. A particulate matter purification module is provided between the second valve and the first valve.

[0019] Furthermore, the return air module includes a return air valve and a return air quality sensor. The return air valve is arranged on the housing. The inlet and outlet of the return air valve are respectively communicated with the return air cavity and the room, so that indoor air enters the return air cavity through the return air valve. The return air quality sensor is arranged in the return air cavity.

[0020] Furthermore, the blowing air module includes a blower, an air outlet, and a main refrigeration / heating module. The blower, the air outlet, and the main refrigeration / heating module are all arranged in the blowing air placement space inside the blowing air placement bin.

[0021] The blower is arranged in the blowing air placement space, and its inlet and outlet are respectively communicated with the blowing air cavity and the blowing air placement space.

[0022] The air outlet is arranged on the housing, and its inlet and outlet are respectively communicated with the blowing air placement space and the room. The main refrigeration / heating module is arranged between the air outlet and the blower. The blower introduces the air in the blowing air cavity into the blowing air placement space, and after the temperature and humidity are processed by the main refrigeration / heating module, it is sent to the indoor space through the air outlet.

[0023] Furthermore, the exhaust air module is composed of an exhaust fan, an exhaust air check valve, a fresh air return air exhaust port, a toilet exhaust port, and an exhaust air placement bin.

[0024] The exhaust air placement bin is arranged in the return air cavity. The exhaust fan, the exhaust air check valve, the fresh air return air exhaust port, and the toilet exhaust port are all arranged in the exhaust air placement bin.

[0025] The inlet and outlet of the fresh air return air exhaust port are respectively connected to the inside of the return air cavity and the exhaust air installation bin, the inlet and outlet of the toilet exhaust port are respectively connected to the indoor toilet and the inside of the exhaust air installation bin, the inlet and outlet of the exhaust air check valve are respectively connected to the inside of the exhaust air installation bin and the outside, and the outlet of the exhaust fan faces the exhaust air check valve.

[0026] Furthermore, the control module includes a strong electricity unit, an edge computing unit, a weak electricity unit, an indoor environment multi-parameter detector, and a human body perception sensor.

[0027] The strong electricity unit is used to transmit energy to the fresh air module, the air supply module, the exhaust air module, and the return air module, while the weak electricity unit is mainly used for signal transmission and control between the fresh air module, the air supply module, the exhaust air module, and the return air module.

[0028] The indoor environment multi-parameter detector detects indoor environment parameters.

[0029] The human body perception sensor is arranged at the bottom of the housing and is used to detect human activities.

[0030] The edge computing unit processes the signals collected by the indoor environment multi-parameter detector, the human body perception sensor, the fresh air quality sensor, and the return air quality sensor, and controls the fresh air module, the air supply module, the exhaust air module, and the return air module.

[0031] Furthermore, a pretreatment module is provided in the fresh air cavity and located between the fresh air regulating valve and the dehumidification / auxiliary heating and cooling module. The pretreatment module includes a constant temperature electric heater and a primary filter, and is used to pre-treat the fresh air from the outside before it is processed by the dehumidification / auxiliary heating and cooling module.

[0032] Furthermore, a guide plate is provided in the air supply cavity. The direction of the first valve is perpendicular to the direction of the air supply fan. The guide plate is arranged between the first valve and the air supply fan.

It can adjust the air flow path according to the monitoring data and energy-saving requirements, specifically by comparing the PM2.5 content of the fresh air with the PM2.5 content of the indoor air, so as to adjust the air flow path to achieve the purpose of reducing energy consumption.

[0034] And in this solution, the data is processed by the edge computing method in the control module. The edge computing unit is directly arranged inside the housing and is located at the source of data generation, so that the processing efficiency and reliability of the entire device can be greatly improved.

Specific embodiments

[0041] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further elaborated below in conjunction with specific illustrations.

[0042] Refer to Figure 1 , which shows a schematic structural diagram of the multi-parameter air conditioner fresh air purification integrated device for residential use provided by the present invention.

[0043] It can be seen from the illustration that the multi-parameter air conditioner fresh air purification integrated device for residential use provided by the present invention includes six components: housing 100, fresh air module 200, air supply module 300, exhaust module 400, return air module 500, and control module 600.

[0044] Among them, the housing 100 is the structural main body for carrying other components. The fresh air module 200, the air supply module 300, the exhaust module 400, the return air module 500, and the control module 600 are all arranged inside the housing 100.

[0045] Furthermore, a fresh air cavity 111, a return air cavity 150, and an air supply cavity 140 are defined inside the housing 100. The fresh air module 200 is used to introduce outdoor fresh air into the air supply cavity 140 through the fresh air cavity 111. The return air module 500 is used to introduce indoor air into the air supply cavity 140 through the return air cavity 150. The air supply module 300 is used to send the gas in the air supply cavity 140 to the indoor space.

[0046] The fresh air cavity 111 and the air supply cavity 140 are connected through a first valve 160. The fresh air cavity 111 and the return air cavity 150 are connected through a second valve 170. A third valve 130 is arranged between the return air cavity 150 and the air supply cavity 140 for connection.

[0047] A particulate matter purification module 240 is arranged inside the fresh air cavity 111 and on one side of the first valve 160. When the gas enters the air supply cavity 140 through the first valve 160, it can be processed by the particulate matter purification module 240.

[0048] Furthermore, the fresh air cavity 111 is provided with a fresh air quality sensor 220 capable of collecting fresh air PM2.5 concentration data, and the return air cavity 150 is provided with a return air quality sensor 520 capable of collecting indoor air PM2.5 concentration data.

[0049] The control module 600 sets a PM2.5 concentration threshold internally and processes the data detected by the fresh air quality sensor 220 and the return air quality sensor 520 through edge computing. The control module 600 is configured to compare the threshold with the PM2.5 values of the fresh / return air monitored by the fresh air quality sensor 220 and the return air quality sensor 520 and form corresponding control signals based on the comparison results to control the corresponding opening and closing of the first valve 160, the second valve 170, and the third valve 130, so as to dynamically switch the air flow paths of outdoor fresh air and indoor return air leading to the air supply cavity 140.

[0050] The exhaust module is used to exhaust the air inside the housing 100 and the odor air in the toilet to the outside. The control module 600 can collect indoor environmental parameters and control the fresh air module 200, the air supply module 300, the exhaust module 400, and the return air module 500 based on the collected data.

[0051] Furthermore, the following specifically describes the dynamic switching of the air flow paths among fresh air, return air, and supply air by the control module 600 through control signals.

[0052] When the PM2.5 value detected by the fresh air quality sensor 220 is lower than the set threshold and the return air quality sensor 520 is higher than the set threshold, the control module 600 forms a fresh air purification return air signal, and the control module 600 controls the first valve 160 to close, the second valve 170 to open, and the third valve 130 to open. The fresh air enters the return air cavity 150 through the second valve 170 to dilute the return air in the return air cavity 150, and they jointly enter the air supply cavity 150 through the third valve 130;

[0053] When the PM2.5 value detected by the fresh air quality sensor 220 is higher than the set threshold and the value of the return air quality sensor 520 is lower than the set threshold, the control module 600 forms a fresh air purification signal and controls the first valve 160 to open, the second valve 170 to close, and the third valve 130 to open. The outdoor fresh air is purified by the particulate matter purification module 240 and then enters the air supply cavity 150 through the first valve 160, and the return air enters the air supply cavity 150 directly without purification through the third valve 130;

[0054] When the PM2.5 values detected by both the fresh air quality sensor 220 and the return air quality sensor 520 are higher than the set threshold, the control module 600 forms a fresh air and return air purification signal and controls both the first valve 160 and the second valve 170 to open, and the third valve 130 to close. The indoor air enters the fresh air cavity 111 through the second valve 170, so that both the outdoor fresh air and the indoor air are purified by the particulate matter purification module 240 and then enter the air supply cavity 150 through the first valve 160;

[0055] When the PM2.5 values detected by both the fresh air quality sensor 220 and the return air quality sensor 520 are less than or equal to the set threshold, the control module 600 forms a signal indicating no need for purification and controls the first valve 160 to close, the second valve 170 to open, and the third valve 130 to open. The fresh air directly enters the return air cavity 150 through the second valve 170 and combines with the return air and they jointly enter the air supply cavity 150 through the third valve 130;

[0056] This solution integrates the functions of air conditioning, fresh air and purification into one device, and there are switchable air flow channels inside. It can adjust the air flow path according to the monitoring data and energy-saving requirements, and can enter the room directly without purification when the air quality meets the requirements, thus avoiding energy waste.

[0057] This solution specifically compares the PM2.5 content of the fresh air, the PM2.5 content of the indoor air with the set threshold, so as to adjust the air flow path to achieve the purpose of reducing energy consumption.

[0058] This solution does not limit the set threshold, which can be determined according to actual needs.

[0059] The following specifically describes each module in this solution in conjunction with the accompanying drawings.

[0060] Specifically, the housing 100 is specifically a rectangular housing, with a cavity formed inside for accommodating each module.

[0061] Inside the housing 100, there is a fresh air placement bin 110 for accommodating the fresh air module 200 and a air supply placement bin 120 for accommodating the air supply module 300;

[0062] Inside the fresh air placement bin 110, a fresh air cavity 111 is defined, and inside the air supply placement bin 120, an air supply module placement space 121 is defined. A third valve 130 is connected between the fresh air placement bin 110 and the air supply placement bin 120. The third valve 130 divides the internal cavity of the housing 100 into an air supply cavity 140 and a return air cavity 150;

[0063] Furthermore, in this embodiment, the fresh air volume range of the fresh air module 200 is preferably 150 - 250 m³ / h,

[0064] The fresh air module 200 includes a fresh air regulating valve 210. The fresh air regulating valve 210 is arranged in the fresh air cavity 111, located at one end of the fresh air placement bin 110 and communicating with the outside. The fresh air regulating valve 210 is used to introduce outside fresh air into the fresh air cavity 111. At the other end of the fresh air placement bin 110, there is a first valve 160, which communicates with the air supply cavity 140. Between the fresh air regulating valve 210 and the first valve 160 in the fresh air cavity 111, there is a second valve 170, which communicates with the return air cavity 150. Between the fresh air regulating valve 210 and the second valve 170 in the fresh air cavity 111, there are successively arranged a fresh air quality sensor 220, a dehumidification / auxiliary heating and cooling module 230. Between the second valve 170 and the first valve 160, there is a particulate matter purification module 240. The fresh air quality sensor 220 is used to collect fresh air quality data, and the dehumidification / auxiliary heating and cooling module 230 is used to process and adjust the temperature and humidity of the fresh air.

[0065] This solution does not limit the detection range of the fresh air quality sensor 220. By way of example, the fresh air quality sensor 220 can detect the temperature, humidity and PM2.5 concentration data of the fresh air.

[0066] When the fresh air module 200 with such a structure is actually applied, when the quality of the fresh air is high, at this time, the fresh air does not need to be purified. The second valve 170 is opened and the first valve 160 is closed. The fresh air enters the fresh air cavity 111 from the fresh air regulating valve 210, and then successively passes through the fresh air quality sensor 220 and the dehumidification / auxiliary heating and cooling module 230, and then enters the return air cavity 150 from the second valve 170;

[0067] When the quality of the fresh air is poor, the fresh air needs to be purified. At this time, the second valve 170 is closed and the first valve 160 is opened. The fresh air enters the fresh air cavity 111 from the fresh air regulating valve 210, then passes through the fresh air quality sensor 220, the dehumidification / auxiliary heating and cooling module 230, and is also purified by the particulate matter purification module 240. Finally, it enters the air supply cavity 140 from the first valve 160.

[0068] Furthermore, the return air module 500 cooperates with the fresh air module 200. The return air module 500 includes a return air valve 510 and a return air quality sensor 520. The return air valve 510 is arranged on the housing 100. The inlet and outlet of the return air valve 510 are respectively communicated with the return air cavity 150 and the room, so that the indoor air enters the return air cavity 150 through the return air valve 510. The return air quality sensor 520 is arranged in the return air cavity 150 and is used to detect the quality of the indoor air entering the return air cavity 150 through the return air valve 510.

[0069] The detection range of the return air module 500 in this solution is not limited. By way of example, the return air module 500 can detect the PM2.5 concentration value, temperature and humidity of the indoor return air.

[0070] Furthermore, the air supply module 300 is used to send the air in the air supply cavity 140 into the room. The air supply module 300 specifically includes a blower 310, an air supply port 320, and a main refrigeration / heating module 330. The blower 310, the air supply port 320, and the main refrigeration / heating module 330 are all arranged in the air supply placement space 121 in the air supply placement bin 120.

[0071] The blower 310 is arranged in the air supply placement space 121 and its inlet and outlet are respectively communicated with the air supply cavity 150 and the air supply placement space 121.

[0072] The air supply port 320 is arranged on the housing 100 and its inlet and outlet are respectively communicated with the air supply placement space 121 and the room. The main refrigeration / heating module 330 is arranged between the air supply port 320 and the blower 310. The blower 310 introduces the air in the air supply cavity 150 into the air supply placement space 121, and after the temperature and humidity treatment by the main refrigeration / heating module 330, it is sent to the indoor space through the air supply port 320. The range of the air supply volume is preferably 1000 - 150 m3 / h.

[0073] Furthermore, the exhaust air module 400 is composed of an exhaust fan 410, an exhaust check valve 420, a fresh air return air exhaust port 430, a bathroom exhaust port 440, and an exhaust placement bin 450.

[0074] The exhaust air installation chamber 450 is arranged in the return air cavity 150. The exhaust fan 410, the exhaust check valve 420, the fresh air return air outlet 430, and the toilet exhaust air outlet 440 are all arranged in the exhaust air installation chamber 450;

[0075] The inlet and outlet of the fresh air return air outlet 430 are respectively communicated with the inside of the return air cavity 150 and the exhaust air installation chamber 150. The inlet and outlet of the toilet exhaust air outlet 440 are respectively communicated with the indoor toilet and the inside of the exhaust air installation chamber 150. The inlet and outlet of the exhaust check valve 450 are respectively communicated with the inside of the exhaust air installation chamber 150 and the outside. The outlet of the exhaust fan 410 faces the exhaust check valve 450. In such a structure, the fresh air return air outlet 430 introduces part of the fresh air and the return air in the return air cavity 150 into the inside of the exhaust air installation chamber 450. The toilet exhaust air outlet 440 introduces the odor in the toilet into the inside of the exhaust air installation chamber 450. The exhaust fan 410 pumps the gas inside the exhaust air installation chamber 450 to the exhaust check valve 420, and the gas is discharged from the exhaust check valve 420 to the outside.

[0076] The range of the exhaust air volume of the exhaust fan 410 is preferably 50 - 150 m³ / h. By exhausting part of the fresh air and part of the return air in the return air cavity 150 to the outside, the micro-positive pressure of the indoor space can be maintained, and the amount discharged to the outside is controlled by the operating frequency of the exhaust fan 410.

[0077] Furthermore, the control module 600 includes a strong electricity unit 610, an edge computing unit 620, a weak electricity unit 630, an indoor environment multi-parameter detector 640, and a human body perception sensor 650;

[0078] The strong electricity unit 610 is used to transmit energy to the fresh air module 200, the air supply module 300, the exhaust air module 400, and the return air module 500. The weak electricity unit 620 is mainly used for signal transmission and control between the fresh air module 200, the air supply module 300, the exhaust air module 400, and the return air module 500;

[0079] The indoor environment multi-parameter detector 640 detects environmental parameters such as indoor temperature and humidity, PM2.5, CO2, illumination, and noise;

[0080] By arranging the edge computing unit 620 in the housing 100, the detected data can be directly processed without uploading to the outside, which can greatly improve the data processing efficiency and reliability.

[0081] Such as Figure 2 , the human body perception sensor 650 is arranged at the bottom of the housing 100 and is used to detect human activities;

[0082] The edge computing unit 620 processes the signals collected by the indoor environment multi-parameter detector 640, the human body perception sensor 650, the fresh air quality sensor 220, and the return air quality sensor 520, and controls the fresh air module 200, the air supply module 300, the exhaust module 400, and the return air module 500.

[0083] As an example, when the operating noise of the unit is greater than 45 dB(A), if the human body perception sensor 650 detects that there are people moving in the bathroom, the operating frequency of the air supply fan 310 is temporarily reduced to avoid causing discomfort to people.

[0084] Furthermore, in order to further improve the reliability and effect of this integrated device, a pretreatment module 250 is provided in the fresh air cavity 111 and located between the fresh air regulating valve 210 and the dehumidification / auxiliary heating and cooling module 230. The pretreatment module 250 includes a constant temperature electric heater 251 and a primary filter 252, which are used to pre-treat the outside fresh air before it is processed by the dehumidification / auxiliary heating and cooling module 230.

[0085] Furthermore, in order to improve the comfort of the integrated device during actual application, a wet film humidification and fragrance release module 260 is provided in the fresh air cavity 111 and located between the particulate matter purification module 240 and the first valve 160. The wet film humidification and fragrance release module 260 can release fragrance into the air and release it into the air supply cavity 140 through the first valve 160.

[0086] Furthermore, in order to improve the air supply efficiency of the air supply module 300, a flow guide plate 700 is provided in the air supply cavity 140. In this embodiment, the wind direction of the first valve 160 is perpendicular to the wind direction of the air supply fan 310, and the flow guide plate 700 is arranged between the two. The specific surface of the flow guide plate is arc-shaped, which is used to guide the air coming out of the first valve 160 to the air supply fan 310.

[0087] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
