Abstract

In the present invention, the thermoelectric exchanger and the heating/cooling device are manufactured in an integrated form, enabling simultaneous provision of cooling/heating/ventilation functions with a single device, thereby increasing convenience of use and freedom of ventilation equipment, and providing heat transfer to the upper part of the heating/cooling device embedded in the ceiling. At the same time as installing the exchanger, the total heat exchanger sucks in the exhaust air and discharges it to the outside, but supplies the incoming outside air to the air conditioning/heating device to generate cold/heat using the outside air without recycling the indoor polluted exhaust air, thereby improving indoor air quality. Cleanliness, comfort, and quarantine efficiency can be improved, and ventilation efficiency can be improved by configuring the indoor airflow to form a vertical direction. In addition, indoor polluted air can be quickly discharged to the outside, preventing the spread of infectious diseases such as viruses. It can maximize quarantine efficiency by effectively preventing airflow, and can dramatically solve the problem of high virus infection rates due to conventional indoor airflow being formed in a horizontal direction, and by moving the air discharge location as far upward as possible from the human body's breathing height. This relates to a vertical airflow type cooling and heating system that can further improve quarantine efficiency and reduce air pollution by preventing nearby people from coming into contact with the released internal air.

Description

{Cooling-heating system type vertical air current for enhancing disinfection efficiency with total heat exchanger}

The present invention relates to a vertical airflow type cooling and heating system equipped with a total heat exchanger with improved quarantine efficiency. Specifically, the cooling/heating equipment and ventilation equipment are manufactured as an integrated unit, so that at least one of cold/hot air and outdoor air flows into the room from the top. At the same time, it is configured to suck in air from the bottom, then move the sucked air to the top and discharge it, making it possible to simultaneously provide cooling, heating and ventilation with a single device, which not only increases convenience of use and freedom of ventilation equipment, but also improves indoor airflow. By directing it in the vertical direction, the airflow of the conventional air conditioning or ventilation device rotates horizontally, which can dramatically solve the problem of high infection rates such as viruses. In the past, the internal polluted air is cooled/heated to remove the cold/heated air in the indoor space. This relates to a vertical airflow type cooling and heating system equipped with a total heat exchanger that can solve the problem of a significant decrease in air cleanliness, comfort, and quarantine efficiency as hot air is recycled.

Recently, as the industry and urban centers have developed, the time spent living in indoor spaces has increased exponentially compared to the past, and cooling circulation, such as air conditioners and air conditioners, has been used to air cool air into indoor spaces. The penetration rate of air-conditioning devices that supply air or heating devices that supply hot air to indoor spaces has increased exponentially.

Typically, a cooling and heating system usually includes a refrigeration or heating cycle of a compressor, condenser, expansion valve, and evaporator. After inhaling air, the sucked air is cooled or heated using a refrigeration cycle or heating cycle and supplied indoors. It is operated in various ways and is classified into ceiling type, wall-mounted type, and stand type depending on the installation method.

Accordingly, the conventional cooling and heating system recycles low-quality air even if the indoor air is polluted or the air quality is poor, so indoor cleanliness and comfort are significantly reduced, and ventilation is required to solve this problem. Devices or air purifiers, etc. are purchased and used separately, but in this method, each device is an independent device, which makes control cumbersome and reduces convenience of use. In addition, it is difficult to use the heat exchanger as a heat exchanger for the cooling/heating means. Therefore, it has structural limitations that cannot solve the essential problems.

Meanwhile, recently, cases such as Corona 19, Middle East Respiratory Syndrome (MERS), Severe Acute Respiratory Syndrome (SARS), and Avian Influenza (AI) have been transmitted through humans or livestock. As a variety of infectious diseases appear, interest in quarantine systems to prevent the spread of infectious diseases is rapidly increasing.

These infectious diseases are spread to surrounding people through various infection routes, but the main route is respiratory infection.

In particular, in environments where many people are crowded in limited places such as call centers and offices, the spread of the virus and the occurrence of many confirmed infections are common.

However, in the conventional cooling and heating system, 1) when it is a ceiling type, the discharge port that supplies cold air/heat is placed at the top, but the intake ports that suck in air are also placed at the top, so the cold air/heat supplied through the discharge port descends and then flows horizontally. It has the characteristic of being sucked into the intake port by moving and rotating in one direction and rising and falling. 2) When it is a stand type or wall-mounted type, the discharge port and intake port that supply cold air/heat are placed on the side, so the inflow cold air/heat is supplied through the discharge port. It has the characteristic of moving and rotating in the horizontal direction indoors and then being sucked in through the intake port. Accordingly, when a conventional air conditioner is in operation, viruses and internally contaminated air spread horizontally along the indoor airflow, which actually increases the infection rate. And the problem of increased transmission rate occurs.

Figure 1 (a) is an example for explaining indoor airflow when a conventional ceiling-type cooling and heating system is installed, and (b) is an example for explaining indoor airflow when a conventional stand-type cooling and heating system is installed. It's a degree.

As shown in Figure 1 (a), the conventional ceiling-type cooling and heating system 910 is installed embedded in the ceiling forming the indoor space (S).

In addition, the conventional cooling and heating system 910 has a suction part 911 that absorbs air in the center of the front cover, and supplies cold/heat to the indoor space (S) outside the suction part 911 of the front cover. A discharge portion 913 is formed.

This conventional ceiling-type cooling/heating system 910 has the advantage of high cooling/heating efficiency as cold/hot air is supplied from the top.

The conventional stand-type cooling and heating system 920 is installed on the floor of the indoor space (S), as shown in (b) of FIG. 1.

In addition, the conventional cooling and heating system 920 has a discharge part 923 that supplies cold/hot air at the top of the front cover, and a suction part 921 that absorbs air is formed in the front cover or side cover.

This conventional heating and cooling system 910 has the advantage of being simple to install and inspect, making it suitable for narrow spaces.

However, in the conventional heating/cooling system 910, a discharge unit 913 for supplying cold/hot air is installed on the ceiling, but as a suction unit 911 for sucking air is installed on the ceiling, the air supplied through the discharge unit 913 is installed. Cold/hot air descends and then moves and rotates in the horizontal direction, rising and falling, and has an airflow characteristic of being sucked into the suction part 911. The conventional cooling/heating system 920 has an outlet 923 and an inlet for supplying cold/hot air. As (921) is disposed on the side, the cold/hot air supplied through the discharge port (923) moves and rotates horizontally in the room and then is sucked in through the intake port (921).

That is, regardless of the type of the conventional cooling and heating systems 910 and 920, an internal air current with a horizontal motion vector is formed, so when a virus is present in the internal air, the virus spreads due to horizontal movement and rotating air currents. Problems are spreading significantly.

In particular, when infectious diseases such as the highly contagious coronavirus spread as recently, the exhaled air of occupants is shared due to the horizontal internal air current formed by the heating and cooling system, resulting in group infection.

In addition, conventional heating and cooling systems 910 and 920 have the problem that indoor cleanliness and comfort are significantly reduced because they recycle low-quality air back into cold/hot air even if the indoor air is polluted or the air quality is poor. Occurs.

FIG. 14 is a perspective view showing the cover of FIG. 10, FIG. 15 is a cross-sectional view of FIG. 14, and FIG. 16 is an exemplary diagram for explaining the operation process of the cover of FIG. 14.

As shown in FIGS. 14 and 15, the cover body 720 is formed in the shape of a hollow pipe whose inner diameter is the same as the outer diameter of the inner pipe body 710, but whose length is longer than the opening 711 of the inner pipe body 710, It is coupled to the outside of the inner tube body 710, and is coupled to the inner tube body 710 so that it can move up and down in a straight line and rotate.

Additionally, a linear sliding groove 721 is formed on the inner peripheral surface of the cover body 720, extending outward from the inner peripheral surface to the upper and lower ends. At this time, the guide protrusion 713 of the inner tube body 710 is inserted into the sliding groove 721, so that the cover body 720 can move in a straight direction along the guide protrusion 713.

In addition, the length of the sliding groove 721 of the cover body 720 is formed to be a predetermined length larger than the gap between the guide protrusion 712 and the fixing protrusion 713 of the inner tube body 710.

In addition, a fixing groove 722 is formed on the inner peripheral surface adjacent to the upper end of the cover body 720 and extends in an arc direction while being formed outward on the inner peripheral surface. The end of the fixing groove 722 is connected to the sliding groove 721.

When the cover body 720 is rotated in this state, as shown in (d) of FIG. 16, the fixing protrusion 713 of the inner tube body 710 is inserted into the fixing groove 722 of the cover body 720 to cover the cover. The sieve 720 can be fixed.

That is, the user can fix the cover body 720 by moving the cover body 720 upward and then rotating it, and in this state, the filter unit ( 20) can be replaced and inspected quickly and conveniently.

Additionally, the filter installation unit 70 of the present invention has the features shown in FIG. 17 below.

FIG. 17 is an exemplary view for explaining the inner peripheral surface of the cover body and the inclined surface of the inner tube body of FIG. 10.

The outer peripheral surface of the inner tube body 710 of the filter installation unit 70 of the present invention from the point where the flange 714 is installed to the upper end is inclined so that the outer diameter becomes slightly smaller as it moves from the bottom to the top.

At this time, the inner diameter of the cover body 720 is configured to be the same size as the outer diameter of the inner tube body 710 when moved to the lowest position and seated on the flange 714, as shown in (a) of Figure 17. .

That is, as shown in (b) of FIG. 17, when the cover body 720 receives an upward force while seated on the flange 714, the inner peripheral surface is spaced apart from the outer peripheral surface of the inner tube body 710 and is horizontal. The movement is carried out smoothly, and it is fixed by the fixing protrusion 713 to maintain the upwardly moved state without free falling.

In addition, when the cover body 720 moves downward and moves the inner tube body 710 in which the opening 711 is formed, the gap between the inner peripheral surface and the outer peripheral surface of the inner tube body 710 gradually narrows, and in the lowest section, the inner peripheral surface is the inner tube body. By contacting the outer peripheral surface of the 710 and moving downward in an interference fit manner, the opening of the inner tube body 710 is sealed and sealed by the cover body 720, and thus the contaminated air in the room moving upward leaks to the outside. It does not work and moves thoroughly to the suction pipe (11).

By being configured to do so, not only can ventilation efficiency be increased, but indoor polluted air can be quickly discharged to the outside to effectively prevent the spread of infectious diseases such as viruses, thereby maximizing quarantine efficiency. Conventionally, indoor airflow is formed in a horizontal direction. This will dramatically solve the problem of high virus transmission rates.

In addition, the vertical airflow type cooling and heating system (1) of the present invention is installed vertically inside the indoor space (S) and includes vertical-moving pipes whose lower ends are connected to horizontal suction pipes, and whose upper ends penetrate the ceiling and are connected to the suction pipes. By doing so, the discharge location of the vent is spaced upward as much as possible from the human body's breathing height to prevent surrounding people from coming into contact with the released internal air, further improving quarantine efficiency and reducing air pollution.

In addition, the vertical airflow type cooling and heating system (1) of the present invention has suction holes penetrating the inner and outer surfaces of the horizontal suction pipe repeatedly formed in the longitudinal direction, so that the internal contaminated air (intake) is more quickly and thoroughly transported to the outside through the suction holes. By discharging, ventilation and quarantine efficiency can be further improved.

In addition, the vertical airflow type cooling and heating system (1) of the present invention has a filter installation part formed on one side of the vertical-moving pipe, and at the same time, the filter part is detachably coupled to the filter installation part of the vertical-moving pipe, so that the filter can be replaced without using a separate fastening means. This allows filter replacement to be performed conveniently and quickly.

In addition, the vertical airflow type cooling and heating system (1) of the present invention includes a vertical-moving pipe in which a filter installation portion has an opening formed on the outer peripheral surface, and a cover body installed to surround the outer periphery of the vertical-moving pipe, and the cover body is attached to the vertical-moving pipe. By being coupled to enable horizontal movement and rotation, the opening is opened or closed according to the horizontal movement of the cover body, thereby further improving the ease of assembly and disassembly of the filter unit and the convenience of operation.

In addition, the vertical airflow type cooling and heating system (1) of the present invention uses horizontal-suction pipes not only on the floor of the indoor space (S) but also on the desks when in an environment where a large number of desks are crowded inside the indoor space (S), such as a call center or office. By placing it at the rear end of the support plate, the vertical airflow phenomenon can be further activated to effectively prevent virus transmission among occupants, further improving quarantine efficiency.
