The air conditioner may be installed indoors and communicate with the outdoor air passages 12 and the outdoor ducts, or may be installed outdoors and communicate with the indoor air passages 11 and the indoors ducts, windows or walls. It is also possible to be installed to penetrate through the indoor air flow path 11 communicates with the indoor and the outdoor air flow path 12 communicates with the outside.

The air conditioner is preferably installed outdoors in consideration of noise and indoor space utilization of the compressor 21 of the refrigerating cycle 4, the indoor blower 30, and the outdoor blower 40, which will be described later. In addition, an indoor suction duct 13 is connected to the case 2 to guide the indoor air to the indoor air passage 11, and guides the air passing through the indoor air passage 11 to the case 2 to the interior. It will be described that the indoor discharge duct 14 is connected.

The case 2 has a dehumidification and cooling in the indoor air flow path 11 through which the indoor air intake port 15 in which the indoor intake duct 13 communicates and in which the indoor air I is sucked, and the indoor discharge duct 14 communicate. The indoor air discharge port 16 through which the compressed air is discharged is formed.

 The case 2 includes an outdoor air inlet 17 through which the outdoor air O is sucked into the outdoor air passage 12, and outdoor air through which the outdoor air O passing through the outdoor air passage 12 is discharged to the outside. The discharge port 18 is formed.

The case 2 is formed with a barrier 19 for partitioning the outdoor air passage 11 and the outdoor air passage 12.

The case 2 is formed in a rectangular shape as a whole, and the barrier 19 is arranged long in the longitudinal direction of the case 2.

The barrier 19 prevents the indoor air I passing through the outdoor air flow passage 11 and the outdoor air O passing through the outdoor air flow passage 12 from mixing with the case 2. ) And a kind of air guide for forming the outdoor air passage 12, the inside of the case 2 and the first space in which the evaporator 24, etc. are installed;

The second space formed between (2) and the barrier 19 will be described as constituting the outdoor air flow path 12 through the outdoor air intake port 17 and the outdoor air discharge port 18.

The refrigeration cycle 4 includes a compressor 21, a condenser 22, an expansion mechanism 23, and an evaporator 24, in which refrigerant is supplied with a compressor 21, a condenser 22, and an expansion mechanism. The heat is dissipated in the condenser 22 while circulating the 23 and the evaporator 24, and is absorbed by the evaporator 24.

In the refrigerating cycle 4, the compressor 21, the condenser 22, the expansion mechanism 23, and the evaporator 24 are installed in the case 2.

The compressor 21 compresses the refrigerant evaporated in the evaporator 24 and discharges the compressed refrigerant to the condenser 22. When the compressor 21 is installed in the indoor air flow path 11, the compressor 21 is heated by heat radiated from the compressor 21. Since the air I may be heated up, it is preferable to be installed in the outdoor air flow passage 12 or in a machine room partitioned apart from the indoor air flow passage 11 and the outdoor air flow passage 12 in the case.

 The condenser 22 is installed in the outdoor air passage 12 so that the outdoor air O is heated while passing therethrough.

The condenser 22 is disposed between the dehumidifying rotor 6 and the outdoor air inlet 17 so that outdoor air O heated by the condenser 22 regenerates the dehumidifying rotor 6 while passing through the dehumidifying rotor 6. Is installed.

The expansion mechanism 23 is expanded before the refrigerant condensed in the condenser 22 is compressed by the compressor 21, and may be installed in the indoor air passage 11 or the outdoor air passage 12, and the case 2 It is also possible to be installed in the machine room partitioned separately from the indoor air passage 11 and the outdoor air passage (12) inside.

The evaporator 24 is installed in the indoor air passage 11 so that the indoor air I passes through and is cooled.

The evaporator 24 is installed to be located between the dehumidifying rotor 6 and the indoor air outlet 16 so that the dehumidified indoor air O is cooled by the evaporator 24 while passing through the dehumidifying rotor 6.

On the other hand, the dehumidification rotor 6 is a desiccant 7 that absorbs moisture of the indoor air I while the indoor air I sucked into the indoor air inlet 15 passes, and the air is absorbed while passing through the air. And a desiccant rotation mechanism 8 for rotating the desiccant 7.

The desiccant (7) is wound around the ceramic fiber flat paper and corrugated paper alternately in a cylindrical shape, the pores and the surface area is very developed, excellent hygroscopic properties and regenerating, that is, meso silica that can remove moisture even at a low temperature of about 60 ℃ or less ( Meso-Silica (SiO 2)).

Here, meso silica is meso-porous silica, and the spherical silica particles having a particle diameter of 10 to 1000 nm and the silica precursor and the surfactant are reacted in a solvent to grow a cell portion composed of silica and a surfactant component on the surface of the spherical silica particles. When the resultant in which the shell portion is formed is heat-treated to remove the surfactant component of the shell portion, a silica shell portion having pores having a predetermined diameter is formed at the position where the surfactant is removed.

Such meso silica has a pore size of 2 nm to 50 nm.

TABLE 1

sample Hygroscopicity (mL / g) Regeneration temperature (℃) Surface Area BET Zeolite 0.37 153 780 Alumina 0.47 80 327 Meso silica 0.63 48 609

Table 1 shows the results of testing the regenerating region of the desiccant. As a result of comparing meso silica having a size of 200 nm and a pore of 2 nm to 50 nm with zeolite and alumina, as shown in Table 1, In the case of zeolite or alumina, the moisture absorption amount per 1g of the sample is higher, so the dehumidification ability is relatively high, and the regeneration temperature is relatively low, so that the regeneration can be performed with relatively low hot air.

The desiccant 7 is disposed so that a portion of the desiccant 7 is positioned in the indoor air passage 11 and the rest of the desiccant 7 is positioned in the indoor air passage 12. The portion adsorbed is moved to the outdoor air passage 12 and regenerated by the outdoor air O.

That is, the desiccant 7 is disposed over the indoor air flow path 11 and the outdoor air flow path 12, and a portion (hereinafter, referred to as an 'adsorption portion') where moisture is adsorbed while the indoor air I passes therethrough. Moisture is adsorbed / evaporated as parts of the water evaporated while the outdoor air O passes (hereinafter, referred to as “regeneration parts”) are alternately changed.

The desiccant rotating mechanism 8 may be made of a motor in which a rotating shaft is formed at the center of rotation of the desiccant 7, or may be made of a belt wound around the outer circumferential surface of the desiccant 7, and a motor for rotating the belt. .

 On the other hand, the air conditioner as described above is the indoor air blower (30) for sucking the indoor air (I) through the indoor air intake port (15) to pass through the indoor air flow path 11 and discharge through the indoor air discharge port (16), The air blower 40 further includes an indoor blower 40 that sucks the outdoor air O into the outdoor air inlet 17, passes the outdoor air flow path 12, and then discharges the outdoor air O through the outdoor air discharge port 18.

The indoor blower 30 and the outdoor blower 40 may be rotated together by one drive source, may be rotated by each drive source, and each will be described below as having a drive source.

The indoor blower 30 is disposed in the indoor air flow path 11, and includes an indoor fan 32 and an indoor fan motor 34 for rotating the indoor fan 32.

The outdoor blower 40 is disposed in the outdoor air passage 12 and includes an outdoor fan 42 and an outdoor fan motor 44 that rotates the outdoor fan 42.

On the other hand, in the refrigerating cycle, since the heat dissipation of the condenser 22 is greater than the endothermic heat of the evaporator 24, the size of the condenser 22 is larger than that of the evaporator 24, and the outdoor air blown to the condenser 22 ( The indoor fan motor 34 and the outdoor fan motor 44 are driven so that the blowing amount of O) is larger than the blowing amount of the indoor air I blown by the evaporator 24.

The desiccant 7 needs to be the same or similar, without having to greatly differ in the blowing amount of the indoor air I passing through the adsorption unit and the blowing amount of the outdoor air O passing through the regeneration unit.

On the other hand, in the air conditioner according to the present embodiment, when all of the outdoor air O passing through the condenser 22 passes through the regeneration unit of the desiccant 7, power consumption of the outdoor fan motor 44 is increased. Since the pressure loss caused by the regeneration unit of the desiccant 7 and the noise thereof are increased, only a part O ′ sufficient for regeneration of the desiccant 7 of the outdoor air I passing through the condenser 22 is increased. Pass (7), the rest (O ") is made of a structure that does not pass through the desiccant (7).

For example, when the air blower of the indoor blower 30 is 8CMM and the air blower of the outdoor blower 40 is 24CMM, only 8CMM which is a part of the air blown through the condenser 22 is blown to the desiccant 7, If 16CMMs are exhausted without passing through the desiccant 7, the power consumption of the outdoor fan motor 44 is reduced when all 24CMMs pass through the desiccant 7, and the desiccant 7 passes through all the 24CMMs. This results in less pressure loss and less noise.

In the outdoor air passage 12, only a part O ′ of the outdoor air O passing through the condenser 22 flows to the dehumidification rotor 6, in particular the desiccant 7, and the rest O ″ is the dehumidification rotor ( 6) In particular, it is formed to be exhausted to the outside without flowing to the desiccant 7.

For the structure as described above, the outdoor air flow path 12 is formed with a plurality of dispersion flow path portions 50, 60 in which the outdoor air (O) is dispersed between the condenser 22 and the outdoor air discharge port 18, When the dehumidifying rotor 6 is disposed only in any one of the plurality of dispersion flow path parts 50 and 60, part of the outdoor air O may be dehumidified in the dehumidifying rotor 6, in particular, desiccant ( After passing through the distribution flow path part 50 in which the 7 is disposed, it is discharged to the outdoor air discharge port 18, and the rest O ″ of the outdoor air O is the distribution flow path part (without the dehumidification rotor 6 disposed) After passing through the 60, it is discharged to the outdoor air outlet (18).

Here, the plurality of dispersion flow path parts 50 and 60 may include a regeneration flow path part 50 through which the outdoor air O ′ passing through the condenser 22 flows to flow to the dehumidification rotor 6, in particular the desiccant 7. ) And an exhaust passage 60 through which the outdoor air O ″ passing through the condenser 22 does not flow into the dehumidifying rotor 6, in particular the desiccant 7.

In the dehumidification rotor 6, the desiccant 7 is disposed over the indoor air flow path 11 and the regeneration flow path part 50 so that the indoor air I of the indoor air flow path 11 receives the desiccant 7. It dehumidifies while passing, and the desiccant 7 is regenerated by the outdoor air O passing through the regeneration flow path part 50.

Here, the regeneration flow path unit 50 is formed such that one end communicates with the inside of the case 2 and the other end communicates with the outdoor air outlet 18.

Here, the exhaust passage portion 60 is a bypass portion for bypassing the dehumidification rotor (6), in particular the desiccant (7), the rest of the outdoor air heated in the condenser 22, which does not flow into the regeneration passage portion (50) As one end, one end communicates with the inside of the case 2 and the other end communicates with the outdoor air outlet 18.

In particular, the outdoor air flow path 12 and the heat absorbing flow path 84 may be installed so as to allow the outdoor air of the outdoor air flow path 12 to be sucked into the heat absorbing flow path 84. Hereinafter, the heat absorbing flow path suction path 87A is provided. It will be described that the outdoor air passage 12 and the endothermic passage 84 is installed to communicate.
