Detailed Description
According to a first aspect, the present invention relates to a mobile plasma air cleaning device 1 arranged to treat aerosol particles present in an air flow through the device.
Preferably, the device 1 according to the present invention is intended for air purification. By "air purification" is meant obtaining good quality ambient air. Good ambient air quality can be assessed on the basis of several parameters, such as the concentration of Volatile Organic Compounds (VOCs), the concentration of fine particles, such as the concentration of fine particles (PM 10) having a diameter of less than 10 μm, and/or the concentration of fine particles having a diameter of less than 5 μm, and/or the concentration of fine particles having a diameter of less than 2.5 μm (PM 2.5), and/or the concentration of particles having a diameter of less than 1 μm, and/or the concentration of particles having a diameter of less than 0.5 μm, etc.
Such a device 1 comprises at least one power supply chosen in a known manner so as to be able to provide sufficient power to allow the operation of all these components, as well as to provide the ionizer with sufficient voltage to generate a plasma.
The device 1 according to the present invention further comprises an ionizer 2 connected to the power supply and positioned so as to receive the air flow F.
Preferably, such an ionizer 2 comprised in the device 1 according to the present invention may take the form of at least one corona plasma unit comprising a substantially needle-shaped polar electrode and a ground electrode placed opposite to the polar electrode, the corona plasma unit comprising a cylinder substantially centred on the polar electrode and a substantially flat porous membrane perpendicular to the polar electrode. Such an ionizer 2 is therefore capable of generating a plasma through which the air flow will pass, thereby discharging the particles present in the air, so that the latter remain in the at least one electrostatic filter. Such an ionizer 2 is well known to those skilled in the art. Such an ionizer is described, by way of example, in french patent FR 3065615.
The device 1 according to the invention comprises a first filter 3, preferably an electrostatic filter, located downstream of the ionizer 2, this first filter 3 being made of mineral material, such as glass or ceramic, and particularly preferably glass fibers. Advantageously, such a first filter 3 through which the air flow F passes is able to retain the particles discharged by the ionizer 2.
The device according to the present invention further comprises an air overpressure device 4 to allow the setting of an air flow F within the device 1. "providing an air flow within the device" means suction of air to be purified, passing of air through various elements of the device 1, such as the ionizer 2, the various filters 3, 9 and the cooling device 5, and exhausting of air out of the device 1. Advantageously, such air overpressure means 4 may take the form of a fan or a turbine. Preferably, such air overpressure means 4 is a turbine. Such an air overpressure device 4 is advantageously connected to an electric power source. Preferably, the air overpressure means 4 will allow air at 100 to 1700m3Flow rates between/h are sucked in, circulated and blown out. More preferably, the air overpressure means 4 will not allow air at more than 1700m3The flow rate/h is sucked in, circulated and blown out in order to limit the risk of condensation water being carried in the air circuit.
According to a particular embodiment, the device 1 according to the invention also comprises at least one second filter 9 located upstream of the ionizer 2. Preferably, the at least one second filter 9, located upstream of the ionizer 2, is a mechanical filter, suitable for allowing air to enter the device 1 according to the present invention, while retaining large particles. Such at least one second filter 9, located upstream of the ionizer 2, may be made of a flexible foam-like material such as polyether or fabric.
According to another particular embodiment, the device 1 according to the present invention also comprises at least one catalyst 10 located downstream of the ionizer 2, this catalyst 10 allowing for the decomposition of ozone. In fact, the ionizer with the plasma cell generates ozone, the oxidizing power of which enhances the removal of the residual contaminants after passing through the plasma cell. Now, the ozone generated by the ionizer 2 must be removed from the air flow before it leaves the device 1 according to the present invention, which is advantageously made possible by the catalyst 10 contained in the device 1 according to the present invention. Such catalyst 10 may be selected from activated carbon, zeolite or manganese oxide (MnO2) which are suitable for the rapid decomposition of ozone and nitrogen oxides at room temperature. Such catalyst 10 preferably takes the form of a honeycomb substrate (e.g. of aluminium) coated with manganese oxide. Advantageously, such honeycomb substrate should be at least 10 millimeters thick to sufficiently effectively neutralize ozone.
Particularly advantageously, the device 1 according to the invention comprises at least one cooling device 5 suitable for cooling the air flow F to the desired temperature. The cooling device 5 is positioned so as to receive the air flow F upstream of the ionizer 2.
According to a first embodiment, the cooling device 5, 5' of the device according to the invention is a refrigerating device 5. "refrigeration device" or freezing device refers to a mechanical device for refrigeration by a thermodynamic cycle based on compression and expansion of a refrigerant and removal of heat in a heat exchanger (plate condenser).
In detail, the refrigeration device of the device according to the present invention may comprise a refrigeration circuit comprising an evaporator suitable for ensuring the transfer of heat from the air flow to be cooled to the refrigerant, a compressor suitable for ensuring the compression of the refrigerant and discharging it to the condenser, a condenser for transferring heat from the refrigerant to the secondary circuit and an expansion valve suitable for injecting the refrigerant into the evaporator. Generally, the refrigeration device may take the form of an air/water heat pump including a variable power compressor. According to a preferred embodiment, the secondary circuit that allows refrigerant heat to be removed from the system is a water circuit, which water comes from a sanitary water network and is discharged to a sewer.
Such a secondary circuit advantageously comprises a pressure switch valve which allows to regulate the circuit water flow rate for the condensation pressure, thus limiting the water consumption of the plant to a strict minimum. Thus, the water flow in the secondary circuit varies according to the compressor power. For example, the water consumption of the secondary circuit of the refrigeration device of the device according to the invention will be: for the compressor power of 0.5kW, the water consumption is 60L/h; for the power of 0.9kW, the water consumption is 100L/h; for a power of 1.4kW, the water consumption is 160L/h. Alternatively, the secondary circuit may be connected to an ice-water circuit connected to a "water cooler" type refrigeration device.
Finally, the refrigeration circuit of the refrigeration device 5 of the device 1 according to the present invention can also comprise any type of sensor for monitoring various parameters (for example the pressure or the temperature of the refrigerant).
This configuration advantageously allows the use of the mobile device 1 of the invention without having to connect the latter to an ice-water pipe network, thereby limiting the installation costs.
According to a second particular embodiment, the cooling device of the device according to the invention is an air/water exchanger 5 'connected to an external cold water circuit 7, wherein the cooling device comprises a water inlet and a water outlet to connect the air/water exchanger 5' to the external cold water (preferably ice water) circuit 7. By "air/water exchanger" is meant any heat exchanger suitable for allowing cooling of the air stream by means of water transferring heat from the air stream to a cold water (preferably ice water) circuit. Such cold water circuits or ice water pipe networks are common in hospitals. As an example, the temperature of the water present in such a cold water circuit may be between 5 ℃ and 10 ℃. Preferably, the air/water exchanger 5' is connected to the cold water circuit 7 by a circuit comprising a regulating valve 11, the regulating valve 11 being adapted to regulate the flow of cold water through the exchanger. The flow rate of cold water through the exchanger will depend on the amount of refrigeration required. For example, a cold (7 ℃) water flow rate of 300L/h would provide 1.5kW of refrigeration, a flow rate of 500L/h would provide 2.2kW of refrigeration, a flow rate of 800L/h would provide 3.9kW of refrigeration and a flow rate of 1200L/h would provide 6kW of refrigeration.
This configuration advantageously makes it possible to limit the noise level during operation of the device 1 according to the invention, compared to a configuration with a refrigerating device 5. Moreover, this configuration allows to reduce the intrinsic power consumption of the device 1 according to the invention during operation.
The cooling device 5 of the device 1 according to the present invention further comprises a condensate tank 8. Such a condensate tank 8 is adapted to recover condensate water produced by an evaporator, an air/water exchanger or a condenser depending on the configuration of the cooling device 5 during air cooling. Preferably, the condensed water tank 8 is made of stainless steel.
Preferably, the condensate tank 8 of the cooling device 5 of the device 1 according to the invention is associated with a level sensor and a condensate pump 8' for evacuation of the condensate tank. As an example, such a level sensor may be an optical sensor adapted to trigger the emptying of the condensate tank by means of a condensate pump. The condensed water is preferably discharged into a waste water system. Such emptying may advantageously limit the hygienic risk of water stagnation in the condensate tank 8.
The device 1 according to the invention also comprises at least two temperature sensors 6, 6' arranged relatively upstream and downstream of the cooling device 5. Advantageously, at least two temperature sensors 6, 6 'are positioned so as to determine the temperature of the air flow F at the inlet and outlet of the cooling device 5, 5'.
The device 1 according to the invention also comprises at least one microcontroller or central processing unit. Such at least one microcontroller of the device 1 according to the invention is advantageously connected to all the electronic components of the device 1, in particular to the temperature sensors 6, 6' arranged upstream and downstream of the cooling means 5, 5', to the at least one cooling means 5, 5' and to the at least one ionizer 2. Such at least one microcontroller of the device 1 according to the invention makes it possible to adjust at least one cooling device 5, 5' according to its upstream measured temperature value (intake air temperature) and downstream measured temperature value (blowing air temperature) in order to obtain the desired temperature value (set temperature) of the air flow F exiting the device 1.
In detail, the microcontroller will calculate the difference between the measured intake air temperature upstream of the cooling device and the set temperature, and will then control (or not control) the operation of the cooling device 5, 5'. The operating parameters of the cooling means 5, 5' can be varied according to the temperature difference calculated by the microcontroller.
As an example, if the at least one cooling device is a refrigerating device 5, the microcontroller may control the speed of the compressor, depending on the thermal load and the set temperature, in order to obtain a temperature of the air flow downstream of the cooling device (blowing air temperature) substantially equal to the set temperature. The speed of the compressor may vary, for example from 12 revolutions per second to 90 revolutions per second.
Still by way of example, if at least one cooling device is an air/water exchanger 5 'connected to a cold water circuit 7, the microcontroller can control the cold water flow rate in this air/water exchanger 5', depending on the characteristics of the cold water circuit and the set temperature, in order to obtain a temperature of the downstream air flow of the cooling device (blowing air temperature) substantially equal to the set temperature. The cold water flow rate in the air/water exchanger may vary, for example from 200L/h to 1500L/h.
Preferably, the device 1 according to the invention will also comprise at least one user interface, preferably in the form of a touch screen, connected to the microcontroller. Such a user interface allows a user to visually monitor the operating parameters of the device according to the invention. As an example, the user interface may display the flow rate of the air flow processed by the device 1, an operating flag of the cooling device 5, 5', the intake air temperature measured upstream of the cooling device 5, 5', the desired set temperature at the outlet of the device 1. Advantageously, the user interface of the device 1 according to the invention allows the user to configure the operating parameters of the device 1 through a touch screen or navigation buttons. As an example, the user interface may allow the user to set a desired temperature of the airflow F exiting the device and a flow rate of the airflow to be processed by the device 1.
According to a particular embodiment, the cooling means 5, 5' of the device 1 of the present invention are advantageously contained in a movable drawer 12. A movable drawer refers to a frame that can be placed in a compartment of the device 1 according to the invention. Such a movable drawer 12 advantageously facilitates the access and removal of the cooling device 5, 5 'to allow maintenance of the cooling device 5, 5', for example.
Other advantages of the invention will become apparent from reading the non-limiting examples given below.
