The heating control device 110 is provided with a first damper 111 for adjusting the amount of outside air installed and supplied to the outside air inlet 10, and a second for adjusting the amount of air discharged and installed in the circulating air discharge unit 20. The third damper 113 controls the amount of air passing through the outside air inlet 10 and the circulating air outlet 20 while connecting the damper 112, the outside air inlet 10, and the circulating air outlet 20. Consists of.

The heating control device 110 is the first damper 111 and the second damper 112 while repeatedly circulating the indoor air using hot water introduced through the hot water heater 52 in the state in which the third damper 113 is opened. By opening a small amount of), the room is heated and the room is ventilated.

On the other hand, the heat pipe 121 is installed in the circulating air discharge unit 20 in the configuration as described above, it is possible to additionally configure the laundry drying rack 120 in which the heat medium oil inside the heat pipe 121 is circulated therein.

This configuration can be used to quickly dry the laundry using the hot air discharged from the circulating air discharge unit (20).

In the above configuration, the outer wall and the first partition 22, the second partition 51, and the third partition 61 constituting the air-conditioning installation of the present invention in the wall is 80㎛ on one side, 200 on the other side It is preferable that it is made of 탆 and filled with a foamed urethane flame retardant therein.

In the above configuration, the control of each device may be configured to install a sensor capable of measuring temperature and humidity for each part, and to connect the sensor and the control device to control using a program built in the control device.

An operation example of the four seasons ventilation type air-conditioning facility of the present invention configured as described above will be described with reference to the accompanying drawings.

Looking at the process of supplying air to each room through the indoor air supply unit 80 from the outside air inlet unit 10 during cooling through FIG. 6, the air passing through the first air inlet louver 14 is first pre-filter 11. The dust is removed while passing through), the odor in the air is removed while passing through the carbon filter 12, sterilized while passing through the ultraviolet sterilizer 13, and then subjected to the first damper 111 and then the dehumidifying rotor 30. Will pass.

At this time, the first damper 111 is completely open.

When the first outdoor air temperature is 35 ° C and 95% relative humidity, moisture is removed while passing through the dehumidification rotor 30 to the dehumidification rotor 30 heated by the hot water heater 52 in the adjacent air heating unit 50. As a result, the temperature rises, the temperature is 50 to 60 ° C, and the relative humidity is about 5 to 15%.

In this state, when the outside air passes through the first heat exchanger 60, the temperature is 35 to 40 ° C. and the relative humidity is 20 because the heat is exchanged with the low temperature circulating air supplied to the first heat exchanger 60 after circulating the room. ~ 25% or so.

Then, the second heat exchanger 71 adjacent to the first heat exchanger 60 passes through the second heat exchanger 71. Since the second heat exchanger 71 is supplied with a constant of 1 to 18 ° C. in a direction crossing the moving direction, the air temperature is increased. It will fall further, at this time the temperature is about 24 ~ 28 ℃, relative humidity is about 30 to 40%.

delete

At this time, the relative humidity may be about 5 to 10% less than the appropriate humidity in this case, by operating the humidifier 81 is to increase the relative humidity more.

The air passing through the humidifier 81 is supplied to each chamber through the supply fan 82 and the transfer device 83.

In the above process, the air supplied to each chamber has a temperature of about 20 to 28 ° C. and a relative humidity of about 40 to 60%, which is suitable for real life.

In other words, when the temperature is the hottest in the summer, the air with a temperature of 35 ° C and a relative humidity of 95% has a relative temperature of 20-28 ° C by using a supply of cooling water and a supply of hot water without a component that consumes excessive power such as an air conditioner. Humidity is 40 ~ 60% to be economical four seasons cooling equipment.

delete

Meanwhile, referring to FIG. 6, a process of discharging air circulated in the room during cooling is performed, and the air circulated through each chamber is introduced into the circulating air inlet 90 while dust is removed through the second prefilter 91. do.

The air flowing into the circulating air inlet 90 has a temperature of approximately 28 to 29 ° C. and a relative humidity of 60 to 70%. The air exchanges heat with the outside air through the first heat exchanger 60. The temperature rises to about 40 ° C.

Thereafter, the air heating unit 50 passes through the air heating unit 50 and is heated by a hot water heater to increase the temperature to about 70 to 85 ° C., thereby drying the dehumidifying rotor 30.

Air introduced into the circulating air discharge unit 20 through the dehumidification rotor 30 is discharged to the outside air while lowering to about 45 ~ 55 ℃.

In this case, when the heat pipe 121 is installed on the circulating air discharge unit 20 and the clothes dryer 120 is provided, the heat pipe 121 is deprived of heat while passing through the heat pipe 121, and the final discharge is about 35 to 40 ° C. The temperature is discharged to the outside.

Looking at the above process it is possible to maintain the temperature and humidity suitable for indoor living while having a process of continuously accepting the outside air in the summer to discharge the circulated outside air.

In addition, since the high-pressure compressor is not operated, it is possible to prevent excessive power loss due to the use of a conventional air conditioner.

Looking at the heating process using the heating and cooling equipment of the present invention through FIG.

First, when the first damper 111 and the second damper 112 are 80 to 100% closed while the third damper 113 is opened, the hot water heater 52 supplies hot water to the inside through the hot water heater 52. The air heated by) passes through the dehumidification rotor 30 and then passes through the third damper 113 without moving from the circulating air discharge unit 20 to the discharge fan 21 side and then into the external air inlet unit 10. After the flow through the dehumidification rotor 30 again, the first heat exchanger 60, the second heat exchanger 70, and the indoor air supply unit 80 are supplied to the room.

At this time, when the cooling water supply pipe 74 attached to the second heat exchanger 71 is supplied into the chamber without operating, the warm air is supplied to the room.

Here, the first damper 111 and the second damper 112 selectively opens only a small amount when ventilation is required so that ventilation can be achieved.

That is, the air heated by the hot water heater 52 after passing through the circulating air inlet part is mostly circulated through the third damper 113 and only a part of the air is discharged through the second damper 112. Will be.

The four seasons ventilation type air-conditioning equipment of the present invention configured as described above can be installed in office buildings such as apartments as well as apartments, etc., and can effectively perform ventilation and heating without using air conditioners.
