Description

DETAILED DESCRIPTION OF THE INVENTION The present invention sends air in rooms such as hospital rooms and sterile work rooms to a water spray cooling cyclone to remove dust, bacteria, etc., and turns the air into low-temperature and humid air, which is heated and regulated. A dust removing bacteria air conditioning system that sends air to a humid cyclone to raise the temperature to an appropriate level and lower the relative humidity to the optimum condition, and is equipped with a heat exchanger that uses heat radiation from a refrigerator to raise the temperature of the air. Regarding equipment.

Generally, in an air conditioner, in order to obtain the desired temperature and humidity, the temperature of the water sprayed by a water spray cyclone is set at 0℃ to 90℃, and by spraying any water between 0% to 90%. Air with near saturated humidity can be obtained. If this air is sent to a temperature regulating cyclone and heated, the humidity will decrease as the temperature rises.
By cooling, the air can be brought to a desired temperature with saturated humidity. Therefore, as long as you calculate the desired temperature and humidity in advance and determine the temperature of the sprayed water and the temperature in the temperature control cyclone, you can easily maintain the desired constant temperature and humidity of the air. However, such an air conditioner has already been disclosed.

The purpose of the present invention is to further increase the thermal efficiency of the air conditioner as described above by utilizing the heat dissipation of the refrigerator that is used to cool the air and then using that amount of heat to heat the air. An object of the present invention is to provide an air conditioner equipped with an exchanger.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the dust removal and bacteria air conditioning system according to the present invention will be described in detail below with reference to the drawings. 1 is a room such as an operating room, a sterile work room, a fresh food processing area, a fresh food storage room, and a hospital room. The chamber 1 is provided with an air intake port 8 for taking in fresh, sterile air and an air exhaust port 7 for exhausting room air. Reference numeral 2 denotes a water spray cooling cyclone that sprays water onto the air from inside the room 1 and cools it. Inside the cyclone 2, a water pipe 10 having a large number of spray ports 9 and a cooling spiral pipe 11 through which refrigerant from a refrigerator flows are arranged. The chamber 1 and the water spray cooling cyclone 2 are connected by a conduit 12, and a fan F is installed in the middle of the conduit 12.
and a surplus air exhaust port 13 are provided. 3 is a water droplet removing cyclone, which is connected to the cyclone 2 by a conduit 14. 4 is a cyclone for heating and humidity control; the cyclone 4 is connected to the cyclone 3 through a conduit 15;
It is connected to room 1 by. A heating hot water spiral pipe 17 and a water jet pipe 18 are arranged in the cyclone 4 . 5 is a heat exchanger, and the heat exchanger 5 is provided with a heating hot water spiral pipe 21, a submersible pump P ₁ , a water injection pipe 22, a heater 23, a ventilation fan 24, and an air intake port 25. Heating hot water spiral pipes 17 and 2
1 by conduits 19 and 20,
Water is circulated inside by actuation of pump _P2 . 6 is a refrigerator, and water heated by the heat radiation of the refrigerator 6 is circulated between the heat exchanger 5 and the refrigerator 6 through conduits 26 and 27. The refrigerant of the refrigerator 6 circulates through the cooling spiral tube 11 in the cyclone 2 through conduits 28 and 29. In the figure, 30, 31, 3
2, 33, and 34 are valves. A indicates the air flow direction, B indicates the coolant flow direction, C indicates the water flow direction, and D indicates the water flow direction.

Next, the operation of the dust removing bacteria air conditioner according to the present invention will be explained. The air in the chamber 1 is drawn out by the fan F and blown tangentially through the conduit 12 into the water spray cooling cyclone 2. In some cases, surplus air can be exhausted from the surplus air exhaust port 13 by opening the valve 30. Furthermore, if necessary, a sterilizing cyclone (not shown) is provided in the middle of the conduit 12, which can sterilize the air by jetting out steam. The air blown into the water spray cooling cyclone 2 passes through the water pipe 10 and is removed from dust and bacteria by the water sprayed from the spray port 9, and further comes into contact with the cooling spiral pipe 11, so that the temperature of the air reaches, for example, 2. °C, humidity
Cooled and humidified to 100%. The cooled and humidified air is then fed through the conduit 14 to the water droplet removal cyclone 3 to completely remove the water droplets contained in the air. Air from which water droplets have been removed, for example, at a temperature of 2° C. and a humidity of 100%, is blown into the heating and humidity controlling cyclone 4 through the conduit 15 in a tangential direction thereof. Here, the air comes in contact with the heating hot water conduit 17 and is heated, for example, to a temperature of 15° C., and the relative humidity is reduced to about 60%. The heating and humidity control cyclone 4 is provided with water jetting pipes 18 for cleaning at the upper and lower parts thereof, so that cleaning water can be jetted into the spiral pipe 17 toward the inner surface of the cyclone body and the outer surface of the air discharge pipe. There is. Valve 31,3
2 and 33 are provided at the bottom of each cyclone 2, 3, and 4, and are used to drain the cleaning water inside the main body, the drain,
Dust, etc. can be discharged. Air whose temperature and humidity have been controlled by the temperature and humidity control cyclone 4 is sent into the chamber 1 through a conduit 16. The air is then circulated through the above path.

Next, to explain the water flowing through the heating hot water spiral pipe 17 in the cyclone 4, water that is sufficiently heated while flowing through the heating hot water spiral pipe 21 arranged in the heat exchanger 5 is pumped by the pump _P2 . It is sent through a conduit 19 to a heating hot water spiral tube 17 in the cyclone 4 . In cyclone 4, the air blown in (approximately 1
℃, relative humidity of about 100%) is heated by the hot water flowing through the spiral tube 17 (for example, about 15℃, relative humidity of about 100%).
60%), that is, the hot water is cooled by heat exchange with air, and is returned to the heating hot water conduit 21 in the heat exchanger 5 through the conduit 20. In this way the water is circulated and the air can be heated.
The water flowing through the spiral tube 21 is heated as follows. Water is heated using the heat radiation of the refrigerator 6. The heated water is pumped through conduit 27 to submersible pump _P1 . Hot water is injected into the heat exchanger 5 from the water injection pipe 22 by the submersible pump _P1 . The injected hot water contacts the heating hot water spiral tube 21 and heats the water flowing therein. That is, the injected hot water exchanges heat with the water in the spiral tube 21. The water that has undergone heat exchange with the water in the spiral tube 21 is returned to the refrigerator 6 through a conduit 26 to be heated again. The water is thus circulated and serves the purpose of heat exchange. If necessary, for example, when heating by heat radiation from the refrigerator 6 is insufficient, the heater 23 can be operated to heat the water. In addition, if the inside of the heat exchanger 5 becomes too heated, the ventilation fan 24 is operated to take in atmospheric air from the atmospheric intake port 25.
It is also possible to adjust the desired temperature conditions by ventilation.

With the above configuration, the temperature and humidity of the air in the room 1 can be adjusted very easily with preferable thermal efficiency. In other words, it is extremely easy to adjust the air to, for example, about 2°C and 100% relative humidity, and if the air in that state is heated to, for example, about 15°C, the relative humidity will inevitably change. Humidity drops to about 60%. Therefore, it is naturally possible to heat and humidify the air to approximately 15°C and humidity to approximately 60%. Moreover, since the heat exchanger 5 is used in the present invention, the heating of the air can be adjusted very easily, and the heat dissipated from the refrigerator used to cool the room air is used to humidify the air. It is highly thermally efficient and energy saving. In other words, it is possible to utilize waste heat.
