In the technical scheme, the fluid is disinfected and sterilized by the CEP module 2 before entering the interior of the shell 1. The CEP technology utilizes a high-pressure ionization technology to generate plasma, the cell walls of bacteria and the proteins of viruses are damaged, the bacteria and the viruses are killed, the particulate debris falls on the CEP module 2, and the particulate debris can be removed by regular cleaning.

Because the size of the inner cavity 11 of the casing 1 of the air conditioner is limited, in some embodiments, the CEP module 2 is fixed outside the casing 1, so that the size of the CEP module 2 can be as large as possible on the premise that the cabin space size meets the installation requirement, the sterilization and disinfection effect is improved, and the installation space inside the casing 1 is saved.

Referring to fig. 3, in some embodiments, CEP module 2 includes a frame (not shown), a filtration layer 21, at least one treatment layer, and a reduction layer 24. The filter layer 21, the treatment layer and the reduction layer 24 are all drawably mounted to the frame. In some embodiments, two process layers are provided as an example: a first treated layer 22, a second treated layer 23. The four layers of the CEP module 2 are in turn: a filter layer 21, a first treated layer 22, a second treated layer 23, and an ozone reducing layer 24.

The first and second treatment layers 22 and 23 each include tungsten filaments and dust collecting plates. The tungsten wire comprises one or more than one wire. The filter layer 21 is provided with an air inlet 211, and the reduction layer 24 is provided with an air outlet 241.

The ozone reducing layer 24 includes a carrier (such as an aluminum honeycomb) and an ozone decomposition catalyst. The ozone decomposition catalyst is coated on the carrier. The ozone decomposition catalyst is contacted with ozone to decompose and reduce the ozone. The aluminum honeycomb is used as a carrier, the contact area of the ozone decomposition catalyst and the ozone is large, the contact is sufficient, and the ozone decomposition efficiency is high.

In some embodiments, the air conditioner further includes a fan 3, a first filter 4, and a heating element 5. The fan 3 is arranged in the inner cavity 11; a first filter element 4 is mounted in the internal cavity 11 and is located between the CEP module 2 and the fan 3. The heating member 5 is installed in the inner cavity 11 to be disposed adjacent to the first filtering member 4 to heat the first filtering member 4. The first filter member 4 employs a high-density filter net. The high-density filter screen is a filter screen with the filtering effect of more than 95 percent.

The heating member 5 is, for example, an electric heating plate. Add heat member 5 and first filter 4 interval setting, specific satisfaction between them: the heating member 5 can heat the temperature of the first filter member 4 to above a set value to ensure a sterilizing effect.

Referring to fig. 1 and 2, in some embodiments, the heating element 5 is located on an upstream side of the first filter element 4.

In some embodiments, the first filter element 4 comprises a HEPA filter. HEPA is an abbreviation for High efficiency particulate air Filter, referred to as High efficiency air Filter. HEPA filters are characterized by air passage but not fine particles; HEPA filters are the most effective filter media for smoke, dust and bacteria, and other contaminants, with an effective rate of 99.7% for filtering particles of sizes greater than 0.1 micron. HEPA can be made of one of the following materials: PP filter paper, glass fiber, composite PPPET filter paper, melt-blown polyester non-woven fabric and melt-blown glass fiber.

Referring to fig. 1, in some embodiments, the air conditioner further includes a temperature measuring element (not shown) disposed in the interior cavity 11, the temperature measuring element being configured to measure the temperature of the first filter element 4. The temperature measuring element is, for example, a bulb. If the temperature of the first filter member 4 measured by the temperature measuring element is higher than a set value, such as 60 ℃, the heating member 5 is maintained in the original working state; if the temperature of the first filter member 4 measured by the temperature measuring element is lower than a set value, for example, 60 c, the heating member 5 needs to increase the heating temperature so that the temperature of the first filter member 4 is not lower than the set value. The temperature of the first filter element 4 is kept above a set value, so that viruses and bacteria can be effectively killed.

The working process of the air conditioner provided by the embodiment of the invention is described below.

Taking the air conditioner for a ship as an example, the air conditioning unit is a marine integral water cooling cabinet machine. An indoor unit 6 is arranged in the casing 1 of the air conditioner, and the indoor unit 6 is positioned in the upper space of the casing 1 of the unit. Refrigerant conveying and distributing are carried out among all refrigeration parts of the air conditioning unit through copper pipes. Heating member 5 passes through panel beating support fixed mounting on indoor set 6, and first filter 4 keeps safe distance with heating member 5, and first filter 4 is located heating member 5 one side towards fan 3. The first filter element 4 is spaced from the heating element 5 such that the temperature of the first filter element 4 can be heated to a predetermined value (e.g. 60 c) or higher, and viruses filtered on the first filter element 4 can be effectively killed in the case of heating for longer than 30 minutes. The CEP module 2 is mounted on the unit side plate and located outside the cabinet 1.

The air conditioning unit can normally realize the original functions of air conditioners such as air supply, refrigeration, dehumidification and the like, and can realize the air purification function. The various modes of operation are described one by one.

After the refrigeration mode is started, the unit applies energy to refrigerant vapor through the compressor to increase the pressure and the temperature of the refrigerant vapor, then the refrigerant vapor is changed into low pressure through the condensation of the shell-and-tube condenser and the throttling process of the thermal expansion valve, low-temperature refrigerant liquid is evaporated into vapor in the evaporator, and heat is obtained from the surrounding environment to reduce the temperature of secondary refrigerant (air), so that the aim of artificial refrigeration is fulfilled.

The air purification mode is described below. The air purification mode is started, the unit indoor fan 3 is started, indoor return air firstly enters the filter layer 21 of the CEP module 2 and then flows into the first treatment layer 22 of the CEP module 2, tungsten wires of the first treatment layer 22 are electrified and corona-generated to generate plasma, electrons and ions in the plasma can charge particles in the air, electrons, active substances, photons and the like in the plasma can sterilize and disinfect various bacteria in the air, and the particles and bacterial remains are collected through the dust collection plate of the first treatment layer 22; then treated again by the second treatment layer 23; the air then passes through the ozone reduction layer 24 to reduce the ozone to oxygen.

The return air leaving the CEP module 2 passes through the indoor unit 6, the heating element 5 and the first filter element 4 in that order. After the return air leaves the CEP module 2, viruses such as new coronavirus and the like in the air cannot be completely killed, the virus transmission mainly depends on droplets (the diameter is more than 5 micrometers) and aerosol (0.5-12 micrometers), and the efficiency of filtering particles with the particle size of more than 0.3 micrometer by the first filtering piece 4 (specifically, for example, a HEPA filtering net) reaches more than 99.95%. Therefore, when bacteria and viruses in the return air pass through the first filter member 4, carriers to which the viruses are attached are intercepted by the first filter member 4, and the viruses cannot be further spread. Meanwhile, because the heating element 5 with high temperature is in an opening state, the heating element 5 heats the first filtering element 4 to more than 60 ℃, and the heating element 5 continuously sterilizes the high-efficiency filter screen at high temperature. Experiments prove that the new coronavirus can die after being heated for more than 30 minutes at the temperature of more than 56 ℃. According to the air conditioning unit provided by the technical scheme, when the first filtering piece 4 is heated, the surface temperature of each area on the first filtering piece 4 can reach more than 60 ℃, so that the sterilization and disinfection effects can be well realized.

The automatic purge mode and the cooling mode described above may be alternated: the air conditioning unit is full of a plurality of hours with the refrigeration mode, and the compressor stops, and fan 3 is with low windscreen operation, and heating member 5 is opened and is heated 4 continuously to first filtration piece, and first filtration piece 4 heats up to more than 56 ℃ rapidly, and the unit is controlled the filter screen temperature range through the temperature sensing package, heats more than 30 minutes after continuously, and heating member 5 stops working. Subsequently, the air conditioning unit is restarted in the cooling mode and the compressor is restarted. That is, the air conditioning unit is switched from the automatic purge mode to the cooling mode.

It should be noted that the heating element 5 of the air conditioning unit may be in a working state when the air conditioning unit is in a heating mode, a dehumidification mode, and an air supply mode. Besides the simultaneous permission mode, the automatic cleaning mode may be alternated with any one of a heating mode, a dehumidification mode and an air supply mode, which is similar to the operation mode of the alternation of the automatic cleaning mode and the cooling mode described above and is not described herein again.
