Description
Technical Field
The utility model relates to an air conditioner, concretely relates to air conditioner for building room, this air conditioner includes: a heat exchanger; a filter device having at least one filter; a fan for generating an air flow through the heat exchanger and the filter; a device housing having a housing opening for sucking air and blowing air; and a control device for controlling the air conditioner, the heat exchanger being realized for cooling air and comprising a cooling device arranged in an air flow, the cooling device being formed by a tube through which a gaseous and/or liquid cooling medium can flow and which has fins arranged thereon, through which fins the air flow to be cooled can flow, the air conditioner comprising a disinfection device for the heat exchanger, which disinfection device comprises a heating device with at least one electric heating element, which is arranged in the cooling device, by means of which a surface temperature of the tube and the fins of at least 50 ℃ can be generated, the fan and the cooling device being able to be switched off by means of the control device, and the heating element being able to be switched on when the fan and the cooling device are switched off.
Background
Air conditioners for air conditioning rooms are well known. Typically, the air in the room is cooled by arranging a heat exchanger with cooling means in the supply air stream. The air flow is generated by a ventilator or fan, which may be arranged adjacent to the heat exchanger or at another location. Heat exchangers for cooling an air flow are usually formed by an arrangement of tubes which extend parallel with respect to each other, at a distance of a few centimeters and in the form of coils. In the region of the parallel tubes or tube sections, fins are arranged on the tube sections to achieve good heat transfer from the cooling medium circulating in the coil to the air flow. The cooling means implemented in this way may comprise a liquid, such as water, or a coolant as a cooling medium, which may be fluid or gaseous. The air conditioner may comprise control means for controlling or regulating the temperature of the air flow, by means of which control means the fan speed and the temperature of the cooling medium, and thus the temperature of the air flow, may be regulated.
Air conditioners are a potential source of dispersal of bioaerosols, as condensate can accumulate on heat exchangers having cooling devices. The very humid environment associated with the heat exchanger promotes the growth of microorganisms such as fungi, bacteria and viruses. At the same time, the relevant instructions specify that the air conditioner is unable to supply air to the room that is of poorer quality than the air drawn in by the air conditioner or heating, ventilation and air conditioning (HVAC) system. This is why the air conditioner itself cannot be a source of pollution. Thus, the air conditioner is regularly maintained and cleaned, for example, by performing chlorination. However, this cleaning process always results in costs and is often complicated by the fact that the air conditioners are arranged in a room in a place that is difficult to reach, for example in the ceiling of the room. Especially when a building is equipped with so-called decentralized air conditioners, one air conditioner is located in each of a plurality of rooms, resulting in a very complicated regular cleaning by a person.
SUMMERY OF THE UTILITY MODEL
Therefore, the present invention is directed to an air conditioner for preventing the emission of bio-aerosol.
This object is achieved by an air conditioner having the features of one aspect of the present application.
According to the utility model discloses an air conditioner, especially the air conditioner who is used for building room includes: a heat exchanger; a filter device having at least one filter; a fan for generating an air flow through the heat exchanger and the filter; a device housing having a housing opening for sucking air and blowing air; and a control device for controlling the air conditioner, the heat exchanger being realized for cooling air and comprising cooling means arranged in the air flow, the cooling device is formed by a tube through which a gaseous and/or liquid cooling medium can flow, and the tubes having fins arranged thereon through which an air flow to be cooled can flow, the air conditioner comprising a disinfection device for the heat exchanger, the disinfection apparatus comprises a heating device with at least one electric heating element, which is arranged in a cooling device, the surface temperature of the tubes and fins, which is at least 50 c, can be generated by means of the heating element, the fan and the cooling means can be switched off by means of the control means, and the heating element can be switched on when the fan and the cooling device are switched off, the air conditioner comprising purification means for the air.
The sterilization of heat exchangers that may be contaminated with bacteria due to condensate accumulation caused by cooling is achieved by increasing the surface temperature of the tubes and fins that may be occupied by fungi, bacteria and/or viruses to at least 50 ℃. At a temperature of 50 ℃ on the surface of the tubes and fins, a large number of various bacterial strains can be killed. It is important that the respective temperatures on the surfaces of the tubes and fins are generated for a sufficiently long period of time to at least reduce the amount of bacteria located on the surfaces. At least one electric heating element is provided for generating the surface temperature, since the high temperature can be generated quickly by one electric heating element without effort. The electric heating element can also heat the surfaces of the tubes and fins particularly effectively, because the electric heating element is arranged in the cooling device of the heat exchanger.
Furthermore, during the heating of the tube and fin surfaces by the heating element, the fan generating the air flow is switched off. Otherwise, the surface and the heating element will be cooled by the air flow and the air-conditioned room will likely be supplied with hot air in an undesired manner. The heating element and the fan are switched on and off by means of a control device. The control means may then also switch off the cooling means or prevent a cooling medium from circulating through the pipe when the heating means is switched on. In this case, the control means are thus realized to initiate the switching off of the fan in the cooling means when the control means switch on the electric heating element and to initiate the switching on of the fan in the cooling means when the control means switch off the electric heating element. This enables sterilization of the air conditioner to be particularly effective. In summary, then, the sterilization of the air conditioner or the heat exchanger no longer needs to be performed by a person, but can be initiated by the control device without much effort and without direct access to the heat exchanger.
The disinfection device, the purification device, the filter device, the fan and the heat exchanger may be arranged in a device housing. In this case, the air conditioner can be realized in a particularly compact manner. The device housing may be realized in the form of a cartridge in which the respective components are arranged. The device housing may also be provided with a housing cover or an openable cover via which the inner space of the device housing is accessible. The cover may extend over the entire side of the device housing or housing opening.
The purification device may comprise an irradiation device with at least one ultraviolet lamp capable of emitting UV-C radiation within the device housing. UV-C radiation can inactivate, for example, mold spores, bacteria (e.coli, listeria) and viruses (influenza, coronavirus). For example, the ultraviolet lamp may be formed as a tube and may be disposed at an appropriate position in the inner space of the device case.
Preferably, the uv lamp may be arranged in the air flow, the uv lamp being arranged between the filter and the fan or between the filter and the heat exchanger. By arranging the ultraviolet lamp in the air flow, microorganisms such as fungi, bacteria and viruses carried by the air flow may be killed while still in the air flow. When the ultraviolet lamp is arranged between the filter and the fan or between the filter and the heat exchanger in the inner space of the device housing, microorganisms adhering to the filter, the fan and/or the heat exchanger can also be irradiated with UV-C radiation and safely killed.
Alternatively, a plurality of uv lamps may be arranged in the air flow, wherein the uv lamps may be arranged between the first filter and the heat exchanger and between the second filter and the fan. For example, the air conditioner may be designed such that two filters are arranged in the device housing, for example, on a housing opening for supplying air and a housing opening for discharging air. In this case, the fan and the heat exchanger may be arranged between two filters in the inner space of the device housing, so that one or several ultraviolet lamps may be arranged in each space between the first filter and the heat exchanger and between the second filter and the fan. Furthermore, an additional uv lamp may be arranged between the fan and the heat exchanger. In this way, UV-C radiation can be applied to almost the entire interior space of the device housing, in particular to the air flow guided through the device housing and to the surfaces of the interior space of the device housing exposed to the ultraviolet lamp.
The purification device may comprise a catalytic device having at least one catalytic converter arranged in the air space. In this case, since the catalytic converter is arranged in the air flow, the air which is guided through the device housing can be treated or purified by means of the catalytic converter. In particular, the chemical reaction or the catalytic process can be started by means of a catalytic converter, via which microorganisms and/or undesired molecules located in the air stream are removed.
The catalytic converter may be arranged between the fan and the heat exchanger or between the filter and the heat exchanger in the inner space of the device housing. In this case, therefore, the air flow can be guided through the catalytic converter anyway.
The catalytic converter may be realized such that the odor-generating substance is neutralized in the air flow by means of the catalytic converter. Neutralization can be carried out, for example, by adding an adjuvant via a catalytic converter. For example, the odorous molecules of air may be encapsulated or broken down by cationic hydrocarbons. The cationic hydrocarbon is conditionally attached to molecules that may generate odors due to its charge. These molecules can also be decomposed by oxidation. In summary, it is thus possible to remove unpleasant odours from the ambient air or to suitably purify the air stream supplied by the air conditioner.
The filter may be at least a HEPA filter of filter grade H14. This makes it possible to filter very small particles or microorganisms, such as viruses and pollen, from the air stream.
The surface temperature of the tubes and fins of at least 60 c, preferably at least 80 c, can be generated by means of heating elements. When the surface temperature is at least 60 ℃, substantially known bacteria that may occupy the heat exchanger can be killed. A surface temperature of at least 80 c may ensure that the heat exchanger is likely to be bacteria-free after sterilization.
The heating element can be switched on by means of the control device when the fan and the cooling device are switched off. In this case, the heating element can be used particularly effectively because the heating element and the surfaces of the tubes and fins cannot be cooled by the fan and the cooling device.
After the surface temperature has been generated, the electric heating element can be switched off and the fan and the cooling device can be switched on by means of the control device. When the surface temperature has been generated within a specific period of time, possible bacteria can be killed, which is then why the disinfection can be terminated by switching off the electric heating element again. In order to prevent warm air from blowing into the room to be air-conditioned, the cooling device may first be switched on, thereby lowering the surface temperature of the tubes and fins, and then the fan may then be switched on again, thereby supplying the room with cooled air during normal operation of the air conditioner.
It is advantageous to keep the surface temperature constant for a period of at least three minutes, preferably five minutes. This ensures that any bacteria that may be present are killed.
The surface temperature may be generated at intervals of at least 24 hours. In this case, the control means may comprise a time controller which initiates a regular repeated disinfection of the air conditioner. For example, for an air conditioner installed above a console, sterilization may be performed at intervals of, for example, 24 hours, so that microorganisms emitted via the air conditioner may be excluded altogether.
The surface temperature may be generated in an interval manner according to the operation time of the cooling device. Furthermore, in this case, the time controller of the control device may sum the operating times of the fans and the cooling device, or also the operating times for certain air conditioner modes, in order to then initiate a disinfection of the heat exchanger according to the operating time, for example after a number of operating hours, during which condensate may have accumulated. In this case, the sterilization may be performed as many times as necessary.
The surface temperature may be generated during a standby mode other than an operation cycle of the air conditioner. During the operating period, cooling of the room may be performed by operating the cooling means of the fan, and during the standby mode the air conditioner and in particular the fan and the cooling means may be substantially switched off. For example, the control device may include a time controller that controls the air conditioner based on a specified time to switch between the standby mode and the operation cycle.
For example, during periods when air conditioning of a room is not normally required, the air conditioner may be operated in a standby mode. During the standby mode, the sterilization can be performed by increasing the surface temperature, so that it is not necessary to interrupt the normal operation of the air conditioner for generating the cooling air.
Further, when the control device receives a turn-off signal for turning off the air conditioner, the surface temperature may be generated before the air conditioner is turned off. When the air conditioner and in particular the cooling device is switched off, condensation often occurs on the tubes and fins of the cooling device, since there is no longer an air flow. Then, when the sterilization is performed by raising the surface temperature, it is ensured that the surface is prevented from being occupied with bacteria. After the sterilization is performed, the air conditioner is finally turned off, and the air conditioner can also be changed to the standby mode.
The heating device may comprise a plurality of heating elements extending parallel to the tubes, and the plurality of heating elements may be arranged between the tubes. In this way, the heat exchanger may further comprise a plurality of tubes, which are arranged in a parallel manner and which together form a coil. In this case, the heating elements may be arranged between the tubes such that the heating elements are arranged substantially uniformly between the tubes. Thus, the heating of the tubes and fins by means of the plurality of heating elements can also be performed uniformly. Since electric heating elements are available at particularly favourable prices, a cost reduction can be achieved very quickly.
The heating element may be a heating rod, a heating tape, an infrared heater, and/or a heating hose. In particular, the heating rods are available at a favourable price and can be easily plugged or inserted between the tubes or fins in the cooling device. The infrared heater may also be an infrared lamp aimed at the tube and fins. Furthermore, different types of heating elements may be used to form and implement the heating device.
The heating element may be realized such that the maximum temperature of the heating element is limited to 100 deg.c, preferably to 80 deg.c. Since a comparatively high temperature is not necessary for the sterilization, the maximum temperature of the heating element can be limited, for example, by means of a temperature switch arranged on the heating element. Furthermore, the following heating elements may also be used: the heating element, due to its design, increases the electrical resistance when a defined temperature is reached and can therefore limit its temperature.
Furthermore, the tank of the heat exchanger for collecting condensate of the heat exchanger can be heated by means of the heating device to a surface temperature of the tank of at least 50 ℃. Since the grooves may be filled with condensate, microorganisms may easily become lodged therein, which is why it is advantageous to sterilize the grooves and the tubes and fins by increasing the surface temperature of the grooves. In this case, in particular, it is also possible to generate a surface temperature of the groove of at least 60 ℃, preferably at least 80 ℃.
The device housing and/or the heat exchanger may comprise a coating comprising silver ions. The coating can be applied to all relevant surfaces of the inside of the device housing and/or of the heat exchanger over which the air flow flows. The coating containing silver ions can preventively prevent the inner space of the device case from being occupied by microorganisms or bacteria.
The air conditioner may be implemented as a separate device or as an integrated device, preferably for ceiling mounting and/or use in an operator's compartment. The device housing of the air conditioner may for example be closed and realized for mounting in or on the ceiling of a room. Since it is possible to disinfect and purify the air in the air stream by means of the heating device, special accessibility of the heat exchanger arranged in the device housing must be taken into account.

Detailed Description
The combination of fig. 1 to 3 shows an air conditioner 10 with a heat exchanger 11, which air conditioner 10 is realized for cooling air. In particular, a filter device 13 having filters 14 and 15, a fan 16, and a heat exchanger 11 are arranged in a device housing 12 of the air conditioner 10. The suction and blowing of air takes place via the housing opening 17 and the filters 14 and 15. The suction, marked by the arrow 34, for the air flow takes place in this case via the filter 14, and the blow-out, marked by the arrow 35, for the air flow takes place in this case via the filter 15. The device housing 12 also includes a housing cover 18, where the housing cover 18 is illustrated as open. The heat exchanger comprises cooling means 19 formed by tubes 20 through which tubes 20 a gaseous and/or liquid cooling medium can flow, and the tubes 20 have fins 21 arranged thereon. The tubes 20 are mounted together with fins 21 on a frame 22 of the heat exchanger 11. The heat exchanger 11 also comprises a heating device 23 formed by heating rods 24, the heating rods 24 being inserted in the frame 22 and the fins 21 in openings 25, and the heating rods 24 being arranged in this way parallel with respect to the tubes 22 inside the cooling device 19. The heating rod 24 is connected to a control device (not shown) of the air conditioner 10 via a connection line 26. For the disinfection of the air conditioner 10 or the heat exchanger 11, the fan 16 and the cooling device 19 are switched off by means of the control device, and the heating rods 24 are switched on such that the heating rods 24 produce a surface temperature of the tubes 20 and the fins 21 of at least 50 ℃, preferably 60 ℃, particularly preferably 80 ℃. Thus, the heating device 23 forms a sterilizing device 27 of the air conditioner 10.
The air conditioner 10 further includes a purification device 28 disposed within the device housing 12. The purification device 28 comprises an irradiation device 29 with two ultraviolet lamps 30. The ultraviolet lamp 30 emits UV-C radiation within the device housing 12. One of the ultraviolet lamps 30 is disposed between the filter 15 and the fan 16 or the heat exchanger 11 30. A further ultraviolet lamp 30 is arranged between the filter 14 and the heat exchanger 11 such that UV-C radiation can be applied to substantially the entire inner space 31 of the device housing 12. It is thus also possible to apply UV-C radiation to the air flow guided through the interior space 31 and in this way eliminate bioaerosols or microorganisms such as fungi, bacteria and viruses which are located in the interior space 31.
The purification device 28 further comprises a catalytic device 32, the catalytic device 32 having a catalytic converter 33 arranged in the air flow. The catalytic converter 33 is arranged between the fan 16 and the heat exchanger 11 such that the air flow guided through the device housing 12 is supplied through the catalytic converter 33. The odour-generating substances are substantially neutralized in the air stream by means of the catalytic converter.
