Generally, district heating system differs from individual heating system in which the user who supplies the collective energy supplies the collective energy through piping for heating and hot water supply to a large number of individual users.

In other words, district heating does not have individual heating facilities such as houses, commercial buildings, offices, schools, hospitals, factories, etc. in a single city or a certain area, and a large-scale heat production facility, that is, a cogeneration power plant, (80 ~ 120 ℃), which is needed to supply electricity to the customers through the heat transfer pipe.

On the other hand, dehumidification cooling system using hot water of district heating was developed.

Here, the heat source (1) is any one of a cogeneration power plant, a heat-only boiler, a micro turbine, a small gas engine, and a small gas turbine so that hot water of a large-scale district heating or a small district heating can be used. Here, it is preferable that the heat source 1 is provided with a heat storage tank for storing hot water.

The heat exchanger (3) exchanges hot water produced from the heat source (1) with heat.

Further, the circulation pump 5 circulates hot water heat-exchanged in the heat exchanger 3.

In addition, the heat pipe 7 is connected to the circulation pump 5 to transport and recover the hot water to the region A to be heated.

On the other hand, the user heat exchanger 9 is installed in a management room or the like of the region A for heat supply and is connected to the heat pipe 5 to transmit the hot water of the heat pipe 5 to the heat supply region A.

The dehumidifying cooling device 100 is connected to the hot water pipe P connected to the user heat exchanger 9 and is installed in each household of the heat supply area A and is connected to the hot water pipe P1 The hot water supplied is used to remove the moisture in the air to treat the latent heat load, and the water is evaporated in the dehumidified air to cool the air by lowering the air temperature. Here, the dehumidifying cooling apparatus 100 performs cooling by using a regenerative evaporative cooler (REC), in which a part of the air passing through the dry channel is repeatedly regenerated by the dry channel and the wet channel, Channel, the water is evaporated from the wet channel surface to cool, and the air passing through the dry channel is cooled to a maximum dew point temperature without increasing humidity by absorbing heat from the air of the relatively hot dry channel .

On the other hand, the dehumidification cooling apparatus is filed and published by the present applicant in Korean Patent Registration No. 10-0773434 (dehumidification cooling apparatus for district heating).

2, the local heating dehumidification cooling apparatus 100 includes a case 110, a first filter 120, a sensible heat exchanger 130, a heating coil 140, a dehumidifying wheel 150 An exhaust air blower 160, a second filter 170, an air blower 180, a regenerative evaporative cooler 190, and a direct evaporative cooler 200.

First, the case 110 is formed in the shape of a rectangular metal enclosure, and a partition wall 119 is provided to partition the wet channel 111 and the dry channel 115, and the outside air is exhausted to one end of the wet channel 111 An outside air intake port 113 is formed at the other end of the wetting channel 111 to suck outside air and an air conditioned space CS is circulated at one end of the dry channel 115 A circulation air intake port 116 is formed so that the air is sucked and a supply mechanism 117 is formed at the other end of the dry channel 115 to supply cooling air in the air conditioning space CS. Here, the dry channel 115 of the case 110 is further provided with a cooler exhaust port 118 for exhausting hot air generated during the secondary cooling in the regenerative evaporative cooler 190 to be described later. Here, the circulating air sucked into the circulating air intake port 116 is mixed at a ratio of 70%: 30% so that the inside of the case 110 is kept at atmospheric pressure.

The first filter 120 removes foreign substances and odors contained in the intake air that is installed between the outside air intake port 113 and the sensible heat exchanger 130 in the wet channel 111 of the case 110. Here, the first filter 120 is an antibacterial filter and is preferably installed in the case 110 so as to be easily replaced.

The sensible heat exchanger 130 is formed in a disk shape so as to rotate in the wet channel 111 and the dry channel 115 of the case 110 by a rotation shaft 131 installed in the same direction as the partition wall 119, Exchanges heat between the outside air flowing into the wetting channel (111) and the circulating air flowing into the dry channel (115) through the intake port (113). Here, the sensible heat exchanger 130 is a disk type in which a thin plate of aluminum or the like is formed in a honeycomb shape so as to perform primary heat exchange in order to lower the temperature of the dehumidified circulating air while passing through the dehumidifying wheel 150 to be described later, A separate motor and belt (not shown) for rotating the sensible heat exchanger 130 are provided.

The heating coil 140 is installed between the rear end of the sensible heat exchanger 130 and the exhaust port 112 in the wetting channel 111 of the case 110, To a high temperature. Here, the hot water supplied to the heating coil 140 is hot water generated from any one of a cogeneration power plant, a heat exclusive boiler, a micro turbine, a small gas engine, a small gas turbine, a gas boiler and an oil boiler, 60 to 120 ° C.

The dehumidifying wheel 150 is formed in a disk shape so as to be rotated in the wet channel 111 and the dry channel 115 of the case 110 by a rotating shaft 151 installed in the same direction as the partition wall 119, And is disposed at the rear end of the coil 140 to adsorb and dehumidify the moisture of the circulating air in the dry channel 115 and regenerate the moisture adsorbed by the high temperature outside air of the wet channel 111 by evaporation. The dehumidifying wheel 150 is in the form of a honeycomb disk in which an adsorbent such as silica gel or zeolite is supported to adsorb moisture in the circulating air by a dry adsorption method, 150 and a belt (not shown).

The exhaust blower 160 is installed between the dehumidifying wheel 150 and the exhaust port 112 of the wetting channel 111 of the case 110 to forcibly exhaust the outside air in the wetting channel 111 to the exhaust port 112.

The second filter 170 is installed between the circulating air inlet port 116 and the dehumidifying wheel 150 in the key channel 115 of the case 110 to remove foreign substances and odors contained in the circulating air. Here, the second filter 170 is an antibacterial filter, and is preferably installed in the case 110 so as to be easily replaced.

The air supply blower 180 is installed between the dehumidifying wheel 150 and the sensible heat exchanger 130 in the case 110 of the case 110 to circulate the circulating air in the dry channel 115 to the circulating air supply mechanism 117, .

Here, the amount of hot air exhausted to the cooler exhaust port 118 is 30% of the circulated air. Here again, the recuperative evaporative cooler 190 is constructed such that a portion of the air that has passed through the dry channel in an iterative structure of separate dry and wet channels is configured to pass through the wet channel, Because it is evaporated and cooled, it absorbs heat from the air of the relatively hot, dry channel, so the air passing through the dry channel cools to the maximum dew point temperature without increasing humidity.

The direct evaporative cooler 10 is installed in the upstream side of the regenerative evaporative cooler 190 in the dry channel 115 of the case 110 so as to circulate the circulated air supplied from the regenerative evaporative cooler 190 to 2 Cooled to cool the air in the air conditioning space CS through the air supply mechanism 117 of the case 110.

In Korea, new apartment buildings require ventilation system. Therefore, it is common to install ventilation system on the ceiling of the evacuation space or the balcony (veranda), so that independent control is possible through the air conditioner such as the existing electric air conditioner and the separate controller to be.

Therefore, in order to use an electric air conditioner or other type of air conditioner, an additional air conditioner must be installed separately from the ventilation device. Also, since the indoor unit and the outdoor unit must be installed separately, there is a problem that the installation is troublesome and the installation space is occupied by the complexity of the refrigerant pipe, the drain pipe, and the electric wire.

In addition, since such a conventional air conditioner only serves as a cooling device, there is a problem that it is impossible to humidify and heat the air conditioner in the fall and winter, which is low temperature and low humidity, and in order to solve such a problem, -0102493 (air conditioner), and Korean Patent Laid-Open No. 10-2002-0032617 (unpaid air humidifying device).

However, such a device has a problem in that the volume is relatively increased due to a configuration in which a separate configuration is added to the inside of the main body, and the manufacturing cost is increased.
