Cooling and heating are the four parts of the Cpmpressor, Condensor, Expansion, and Evaporator using the refrigerating device. The cooling goal is achieved, and the heat is generated by generating heat in the evaporator by reversing the gas cycle in the reverse cycle of the heat pump.

Cooling and heating using the pulti effect is based on the principle that when a direct current is applied to a thermoelectric semiconductor, an endothermic phenomenon occurs on one side and an exothermic phenomenon on the other side.

The filtering system includes HEPA filter, medium filter, carbon filter, electrostatic filter, etc., and it removes dust due to the difference in quality of the material, removes odor with the material of the material, and when DC current flows to the electrode plate, By using the principle of adsorption, dust can be removed.

Germicidal lamps are typical of ultraviolet germicidal lamps. They can produce good germicidal effects by selecting the size of the ultraviolet rays.

Ozone sterilization can produce sterilization (viruses, fungi, bacteria) as O _3. There are various methods of generating ozone, such as corona discharge, ceramic, and UV.

Air supply harmless to human body

Air sterilization of the area inside the equipment

Clean room supply to pressure vessels for clean air

Control of refrigeration and air conditioning equipment according to various fluctuations in the amount of air flowing inside the enclosed space (liquid breakage may occur due to liquid bag phenomenon).

Solve Supply Line Contamination Problem-No air cleaning effect if supply is contaminated.

Treatment of condensate at high pressures-Bacteria control required on equipment.

The present invention is a system for supplying clean air by using an air pressure increasing device by installing a fine dust removal device, a constant temperature and humidity device, an air sterilization system, an oxygen supply device, etc. in a pressure vessel to suck 100% outside air into sterile clean air. As a equipment to make, it is a supply of products that allow the human body to individually cool and heat through the air belt while breathing the clean air supplied through the air supply mask.

The outside air is filtered by the air filter 1, and the introduced air is introduced into the first process by raising the pressure using the pressure increasing device 2. The air introduced into the first process is humidified by the humidifier 28 when the humidification is required by the temperature / humidity sensor 16, and the secondary filtering is performed by the medium filter 5. The air introduced into the second process is first sterilized by the sterilizing lamp 21-1 at a wavelength determined by the sterilizing lamp 21-1, and cooling and heating are performed while passing through the cooling coil 6 and the heating coil 7. At this time, cooling is performed by a freezing device. The refrigeration cycle is briefly described. Compressor (24) compresses refrigerant gas and flows into condenser (26-1) coil in the hot gas state, and heat exchange is performed by condenser (26) motor to make the refrigerant into liquid state. The temperature is lowered to achieve the purpose of freezing in the evaporator (6). The heat pump cycle is formed by using the four sides 24-1. At this time, heat is generated in the evaporator (kcal / h), and in the condenser, endothermic (kcal / h). In large sizes, the heat source of the heating coil 7 provides a system to be supplied with hot water or steam from electricity or an oil boiler. 12 is a heating heat source control valve. 16 temperature signals were received to operate proportionally. The air cooled or heated in step 3 is once again sterilized by a sterilizing lamp of the sterilizing lamp 21-2. It is necessary for re-sterilization and the presence of condensed water because of the growth of various germs such as viruses in a humid place at stop. The sterilized air flows into 4 processes, and UV sterilization effect inactivates the energy of ultraviolet rays by destroying the DNA and RNA of microorganisms so that they cannot be metabolized or proliferated forever. The bactericidal effect of ultraviolet rays is mainly caused by the UVC region between 200 nm and 280 nm in the ultraviolet wavelength range. The highest sterilizing effect is 265 nm. The wavelength of 254nm emitted by the low pressure or high output low pressure amalgam lamp also has very high UV sterilization effect, but because it emits only 254nm wavelength due to the characteristics of the lamp, it is known that the wavelength has the highest effect. Having is a proven fact. The germicidal mechanism of ultraviolet light is that the DNA absorbs photons with ultraviolet energy so that no further genetic replication occurs. The most effective ultraviolet wavelength for this action is 263 nm to 275 nm, depending on the target microorganism. Ultraviolet disinfection by this mechanism is unlikely to produce immune microorganisms, unlike disinfection by other chemical methods. Recently, the effects of short wavelength ultraviolet rays on the killing of microorganisms have been studied in depth. This is because the short wavelength ultraviolet rays, which have much higher energy than the ultraviolet rays having long wavelengths around 265 nm, causes the microbial cell membranes to be traumatized. Do not let the osmotic pressure can be controlled by using the point to kill. In the case of a medium-pressure UV lamp that emits ultraviolet light in a wide wavelength range, the above two effects can be simultaneously applied to remove microorganisms very efficiently. The fine filter 8 or fine dust (ultra-high filter) as needed is removed. In the 4th step, high-clean air is combined with oxygen from the oxygen generator and exits to the supply pipe 19. If condensate flows through the air in the supply pipe 19 with moisture or the like, water condensation may occur and water hammer may occur. There is a difficulty in being discharged out by the condensate discharge system 17.

The principle of the condensate discharge system 17 is to discharge the condensate at a high internal pressure, so that the specific gravity of water is greater than that of air, that is, to operate as follows. Condensate treatment process is shown in [1] and [4], the condensate discharge system (9, 17) is a ball (9-1) also rises by buoyancy when the condensate rises to a certain height and the ball (9-1) When the condensate is discharged by air pressure, the valve 9-2 connected to the valve 9-2 is opened, and the condensate level is lowered, and the ball 9-1 is also lowered to close the valve 9-2 connected to the ball 9-1. After the condensate removal device 17 of the supply pipe 19, a high-performance pipe filter was installed to remove foreign substances in the pipe, and the controller 102 was used at the pressure of the supply pipe 19 to enter FIG. 100 and FIG. High purity air is breathed in by a person.

Although air conditioning including sterilization is performed from 1 to 101, when the equipment is stopped, the sterilization system exists from 1 to 4 processes, but there is water in the supply pipe and the sterilization system exists from 1 to 4 processes, but the supply pipe is moisture. The presence and presence of less than four steps in the maintenance process, so the problem of supply pipe sterilization needs to be dealt with deeply. Therefore, the present invention provides a sterilization system using the ozone generator 10.

  Ozone is a molecule in which oxygen molecules are decomposed and recombined into three atoms, and various methods of generating ozone have been developed, such as air-cooled method (no-load system), ceramic method, UV method, ozone lamp method, plasma method, corona discharge method. Etc. have been developed. Ozone has strong oxidizing power, so it can be sterilized and inactivated against a wide range of microorganisms including viruses. It is relatively easy to repair and manage, and has various advantages such as deodorization, decolorization, and purification.

By supplying the required amount (ppm) to the ozone generator 10 while supplying air to the pressure increasing device 2 before and after operation with the operation system, the ozone flows through the process and supply pipes so that ozone sterilizes the inside of the supply pipes. I'm trying to. At this time, the ozone amount adjustment is controlled by the ozone sensor 20. When the operation of the ozone disinfection system is completed, the signal is received from the ozone sensor 20 and when the human body permits (ppm), the alarm is stopped and normal operation is provided, thereby providing safe use from ozone. In case of alarm, the solenoid valve 20-1 is repeatedly turned ON and OFF, so that the air supply is unnatural and difficult to wear when the user wears the air supply mask 101 due to the shaking of the air in the supply pipe. System provision.

The differential pressure gauge 22 allows the medium filter efficiency to be visually monitored, and the pressure increasing device 2 is controlled by a signal of the pressure sensor and the control device 29 so as to maintain a constant pressure.

Poor workplace-Individual air-feeding at sites such as scented leather factories, injectors that do not have proper heating and cooling, work environments inside oil tanks that lack oxygen, paint workplaces, dusty workplaces, workplaces in sewers, and coal workshops The mask allows clean air breathing and heating and cooling of the individual body for each individual, thus solving the problem of hot, cold and odorous field work and providing local air cleaning and aseptic facilities.
