Description

Method for controlling integrated operation of complex cooling and heating air conditioner

The present invention relates to a comprehensive operation control method for a complex air conditioning and air conditioning apparatus, and more particularly, radiation for solving the disadvantages of the air-conditioning system dualized by convective cooling and radiant heating of existing residential buildings and the convection air-conditioning system of commercial buildings. The present invention relates to a general operation control method for a combined air conditioning and air conditioning system for optimizing operation control of a cooling and heating air conditioning system in which a system and a dehumidification air conditioning system are combined.

Conventionally, in domestic houses, heating uses radiant ondol floors, and cooling uses convection type air conditioners.

The convection type air conditioner induces air sickness and adversely affects the human body, causing a temperature imbalance phenomenon that feels cold at a short distance and hot at a long distance, and the temperature difference between the upper and lower parts of the indoor space is large, resulting in poor comfort. have.

Recently, as the interest in improving the comfort and energy saving of residents has been heightened, various technically supplemented products are being released. In order to solve the problems of the conventional air conditioners, studies on radiant heating and cooling systems have been conducted in foreign countries. In particular, research is being actively conducted in Europe, and radiative heating and heating systems are applied to real life.

However, in Korea, there are differences in environmental factors, living patterns, and perceptions compared to other countries, which makes it difficult to apply these radiative heating and cooling systems to real life. Therefore, the development of radiant heating and heating system and its control method should be developed for the domestic environment. Such research is the reality of applying experiments at the research institutes of domestic companies and universities.

However, there are limitations to the control methods that have been announced so far to create a stable, maximum efficiency and pleasant environment under domestic environmental conditions, and specific control methods have not been introduced. We did not present an effective solution to prevent the occurrence of the problem, but presented the abstract combined operation of the radiative heating and heating system and the dehumidification and air conditioning system. The conventional technology has a practical difficulty in applying to the current residential environment due to the lack of cooling capacity. .

In addition, if the humidity rises rapidly, such as when cooking food in a kitchen due to the characteristics of domestic residential facilities, there is a risk that the condensation will be reduced and condensation may occur instantaneously with condensation on the ceiling of the kitchen. In order to supply the temperature of the water supply to each room above the temperature at which there is a risk of dew condensation, it is difficult to adjust the room temperature to the set temperature due to low cooling ability. Deterioration of the safety, problems such as deterioration of the finish due to condensation may occur.

The biggest problem in the operation of the radiative cooling system is the occurrence of condensation due to the increase in temperature and humidity in the summer, and when the supply water is supplied at a temperature such that no condensation occurs, the cooling capacity is reduced as described above.

Korean Patent No. 10-0680305 discloses a control method of a cooling and heating system using an ondol and an air system as an example of the prior art for solving such a problem. In the case of the invention disclosed in the prior art, it provides a condensation control method using an air conditioning system at the same time to supply the cold water above the dew point to prevent condensation when cooling the floor radiation, this is to consider the safety for preventing the risk of condensation in the room There is a problem that the cooling performance of the radiation panel is lowered because the temperature of the remaining cold water is increased.

In addition, the prior art does not show the detailed interlocking method of the ventilation system or the air conditioning system applied to the existing multi-family house or commercial building, and stable numerical control of the equipment control, and is a system that can be applied only to cooling the floor radiation of the domestic multi-family house. There is no information on how to control the characteristics of cooling ceiling radiation.

In addition, there is no proposed solution to the problem that the ability to respond to the sudden rise in humidity according to the environmental changes in the room of the prior art, the situation is only discussed for the interlocking operation of the indoor dehumidifier.

On the other hand, the conventional radiation system receives the signal values such as temperature and relative humidity according to the change of the indoor environment of each room, and performs the control operation of the temperature of the water supply and the dehumidification air conditioning based on the environment of the room having the worst condition among them. However, the actual living environment has different load characteristics in each room, and various variables can occur.

Therefore, the technology that can control the radiant air-conditioning system for each room is needed for the change of dew point according to the change of environment of each room. However, the existing domestic and foreign systems cannot provide such control technology and refer to the environment of the room with the worst condition. The operation control method is selected.

However, in case of condensation risk due to sudden change of indoor environment in one room, this system recognizes the environment of the room as a new representative value and performs the whole operation of the copying system. There is a problem that decreases the heating and cooling efficiency, reducing the comfort of the occupants and unnecessary energy waste.

The present invention has been made to solve the above problems, the optimum temperature control and dehumidification air conditioning apparatus for supplying water to perform the maximum control of the heating and cooling capabilities of the radiation system while at the same time performing the safety control function for each dew condensation In addition, the integrated exhaust control system installed in residential buildings must be integrated and controlled to respond quickly to various environmental risk variables such as sudden increase in indoor humidity, and through detailed control methods to create stable environmental conditions, providing optimal and stable indoor environment.

In addition, in order to determine the supply water temperature that is safe for the indoor dew point and to obtain the maximum cooling and heating capability, the optimum supply water must be determined according to the final surface temperature of the actual radiation panel 190. Accordingly, the heat transfer and the finishing material of the radiation panel 190 are determined. Correction according to the material of 185 is necessary. Therefore, the coefficient and the coefficient value according to the type and material of the radiation panel 190 and the finish material 185 is included in the formula, and the coefficient value (K) thereof is an experimental coefficient value according to the thickness of the floor structure 180 as shown in Table 3 below.

Safety values (K, K ') applied when calculating the supply water temperature of the supply water as described above are due to the difference in the structure of the floor and the ceiling of the room, the following describes the difference between the installation structure of the floor and ceiling of the room do.

4 is a view showing an installation example of the (a) floor type radiation system and (b) ceiling type radiation system according to the present invention, as shown in Figure 4 (a) the floor structure 180 is a concrete slab 181 , 210mm thick), radiation panel (182, 20mm thick), lightweight foam concrete (183, 45mm thick), finishing mortar (184, 45mm thick) and finish (185, 10mm thick), the supply water can be circulated The water pipe 186 to be formed may be embedded in the floor structure 180. In addition, the condensation sensor 191 for detecting whether condensation occurs on the indoor floor may be configured to be installed together with the heat conduction plate 192 at a corner of the floor structure 180.

Figure 4 (b) shows the installation state of the ceiling radiation system, the water pipe 186 is installed on the ceiling of each room via the radiation panel 190, the finishing material 185 on the bottom surface of the radiation panel 190. The condensation sensor 191 is a heat sink (not shown) in which the supply water inlet side or the water pipe 186 of the water pipe 186 passing through the radiation panel 190 is installed. It may be configured to be provided in the). This is to accurately detect the initial supply temperature of the feed water when the condensation sensor 191 is installed on the feed water inlet side of the feed pipe 186 because the radiant heat transfer is made in the course of the feed water via the water pipe 186. .

On the other hand, in the case of floor radiation cooling of the control method of the radiation system, the supply water temperature (Tsupply) of the supply water, the floor structure ( 180) The larger of the floor surface temperature (SL) subtracted from the correction factor (K = CF + MF) taking into account the experimental coefficient value (CF) according to the thickness and the experimental coefficient value (MF) according to the material of the finishing material 185. It is preferable to determine the temperature of, which is the same as Equation 6 and Equation 7 below. In this case, the bottom surface temperature (Swater) may be applied to 19 ℃.

When controlling the surface temperature of the floor for the comfort of the human body, it is not possible to cope with the change of dew point due to the change of the indoor environment, and the risk of condensation may occur.

Therefore, in addition to surface temperature control for human comfort, an additional safety control method for dew point change is required, and the final control method determines the maximum value MAX of the calculated values of each room derived by the above formula as the final feed water temperature. To drive.

In order to examine the stability of the safety factor, a virtual simulation was carried out according to various conditions, and the values are shown in Table 6 below. The bottom surface temperature can be seen to vary from 3 to 5 ℃.

This is a matter that must be reviewed for optimal control for human comfort and safety during floor radiant heating and heating control.In accordance with the above formula, the floor surface temperature does not fall below the human comfort temperature during operation and when the dew point increases due to the change of indoor environment. In addition, the maximum surface control is applied to increase the floor surface temperature to maintain the safety of the dew point.

However, the above results indicate that the indoor load is a condition value within 30W, and the surface temperature in the actual residential environment will appear mostly above the experimental value. In addition to the adjustment of the water temperature, it is necessary to suppress the increase in humidity by operating the dehumidification and air conditioning apparatus 200.

Therefore, it is necessary to control and maintain the safe surface temperature by measuring and calculating the condensation risk condition. Therefore, the above-mentioned method for controlling the comfort water temperature to supply cold water to the room at the safest temperature among the calculated values is derived and applied. In addition, a comprehensive control method that satisfies the safety and cooling performance is required by the operation control of the dehumidifier 210 and the combined operation control of the ventilation device 220 and the exhaust device 240 to start and operate in a priority step to the indoor humidity change. .

Figure 5 shows the basic conceptual diagram of the dew point control device of the radiation system according to the present invention, the signal detected by the feed water temperature sensor 160, the flow sensor 170 and the carbon dioxide detection sensor 223, and the condensation sensor 191 ) And a signal detected by the room temperature sensor 311 and the indoor humidity sensor 312 and input through the room controller 310 of each room are transmitted to the main controller 300, and the main controller 300 receives the input of each room. Based on the environmental conditions, the dehumidifier 210, the ventilator 220 and the exhaust device 240 is controlled, and the opening rate of the three-way mixing valve 130 for adjusting the supply water temperature of the supply water is controlled. .

In this case, in order to achieve the indoor environment set by the user in combination with the control step of the radiation system 100, the dehumidification and air conditioning apparatus supplied to the room to cope with various changes in the indoor load by first executing the indoor humidity control operation. Derivation of a control method for controlling the air supply temperature of 200 is required, and the air supply temperature of the dehumidification and air conditioning apparatus 200 is expressed by Equation 8 below.

Here, calculation (AHU) is the supply temperature of the air supplied from the dehumidification air conditioner 200, Rsetpoint is the indoor set temperature, ΔT is the operating temperature range of the dehumidification air conditioner, K is the set margin (coefficient value) according to the characteristics of the indoor environment : 0 ~ 1) It shows the value that can be adjusted by setting variable in the field after actual site installation.

6 to 7, a comprehensive operation control method for a complex air conditioning and air conditioning apparatus according to the present invention will be described.

Referring to FIG. 6, power is supplied to the system (S601), and the user operates the room controller 310 of each room to set the room temperature and simultaneously selects an operation mode of the ventilation device 220 as a manual or automatic mode. (S602). When the ventilation device 220 is operated, the damper of the ventilation device 200 is opened and at the same time, the ventilation function is performed by the rotation of the blower fan (S603 to S605), and the indoor ventilation is performed to detect the carbon dioxide sensor 223. When the carbon dioxide concentration in the indoor air satisfies a condition below the set concentration, the operation of the ventilation device 220 is stopped (S606).

Along with this, the condensation sensor 191 constantly detects whether condensation has occurred in the room (S607), and in the room where the risk of condensation is detected, the dehumidification and air conditioning apparatus 200 stops the operation of the copying system 100. ) To perform dehumidification of the room (S608, S609), and after the risk of condensation is removed, the detection of the condensation sensor 191 is released (S610).

When radiant cooling the room, the indoor temperature is compared with the set temperature (S611), and if the room temperature is higher than the set temperature, the indoor dew point is calculated (S612). When the surface temperature of the radiation panels 182 and 190 installed in each room is lower than the indoor dew point, it is determined that there is a risk of condensation. When the surface temperature of the radiation panels 182 and 190 is higher than the indoor dew point, It is judged that there is no risk of condensation.

When the indoor environment is in a safe state without the risk of condensation, the dehumidification and air conditioning apparatus 200 and the radiation system 100 are operated together, and when the indoor environment is at risk of condensation, only the dehumidification and air conditioning apparatus 100 is operated. In order to lower the temperature of the room by the cooling function of the dehumidification and air conditioning apparatus 100 together with the dehumidification of the room (S613, S614).

And comparing the room temperature and the set temperature again (S615), when the room temperature is lower than the set temperature, the operation of the dehumidification air conditioner 200 and the radiation system 100 is stopped (S616).

If the indoor environment changes over time (S617), the indoor temperature and the set temperature are again compared (S618), and if the room temperature is higher than the set temperature, the dew point is calculated (S619), and the indoor environment causes condensation. If there is a risk, the dehumidification and air conditioning apparatus 200 is operated first, and if the indoor environment is in a safe state without the risk of condensation, by comparing the deviation between the indoor temperature and the set temperature (S620), the set temperature deviation (ΔT) If larger, the dehumidification and air conditioning apparatus 200 and the radiation system 100 are operated together. If the temperature is smaller than the set temperature deviation ΔT, only the radiation system 100 is operated (S621, S622).

When the room temperature becomes lower than the set temperature, the operation of the dehumidification and air conditioning apparatus 200 and the radiation system 100 is stopped (S623 and S624).

The operation control method of the dehumidification and air conditioning apparatus 200 will be described in more detail with reference to FIG. 7. By comparing the set humidity with the measured indoor humidity (S701), when the indoor humidity is higher than the set humidity, the room humidity is compared with the value obtained by adding the set humidity (ΔH = 3%) to the set humidity (S702).

As a result of the comparison, when the indoor humidity is higher than the set humidity plus the humidity deviation, the operation of the exhaust device 240 and the dehumidification air conditioner 200 is performed at the same time, and the room humidity is higher than the set humidity plus the humidity deviation. If small, only the dehumidification and air conditioning apparatus 200 is operated (S703, S706). If the room humidity becomes lower than the set humidity plus the humidity deviation, the operation of the exhaust device 240 is stopped (S704, S705), and if the room humidity becomes lower than the value obtained by subtracting the humidity deviation from the set humidity, The operation of the dehumidification and air conditioning apparatus 200 is stopped (S707 and S708).

On the other hand, by comparing the set humidity and the measured indoor humidity (S701), when the indoor humidity is lower than the set humidity, by comparing the set temperature and the room temperature (S709), when the room temperature is higher than the set temperature, the dehumidification and air conditioning apparatus In operation S710, the set temperature is compared with the room temperature again (S711), and when the room temperature is lower than the set temperature, the operation of the dehumidification and air conditioning apparatus 200 is stopped (S708).

Referring to Figures 8 to 10, the operation sequence of the radiation system will be described, calculate the dew point in the room of each room (S801), and operates the supply water distributor 150 to supply the supply water to the room without risk (S802) In addition, the circulation pump 140 is operated (S803), and the flow sensor 170 detects whether the supply water flows at the set flow rate (S804). In parallel with this operation, the supply water temperature sensor 160 senses the temperature of the supply water (S805), calculates the supply water temperature according to the above-described formula (S806), and the three-way mixing valve so that the supply water is the calculated supply water temperature. The supply water is circulated and supplied to the water pipe 186 installed on the floor or the ceiling of the room while adjusting the opening degree of the 130 (S807). And comparing the set temperature and the room temperature (S808), when the room temperature is lower than the set temperature, the operation of the copying system 100 is stopped (S809).

Referring to Figure 9, based on the room temperature and room humidity measured in each room (room 1, room 2, room n) compared to the set temperature and detection temperature for each room, indoor dew point temperature calculation, supply water temperature determination, three-way mixing Valve control, feed water distributor control and supply of feed water are controlled separately.

Referring to FIG. 10, (a) shows a direction in which supply water is supplied and returned through a supply line 111 and a return line 112 between the copying system 100 and the supply water distributor 150 during a normal operation. , (b) is a part of the supply water returned through the return line 112 by adjusting the opening rate of the three-way mixing valve 130 is branched to the supply line 111 through the bypass line 113 supply line ( 111) shows the action of raising the temperature of the feed water by mixing with the feed water supplied through. For example, when the temperature of the supply water at the point A returned to the radiation system 100 is 19.5 ° C, and the initial temperature of the supply water at the point B supplied from the radiation system 100 is 16.5 ° C, By mixing a portion of the supply water to be supplied to the feed water distributor 150, the temperature of the supply water at the point C can be raised to 18 ℃. In this way, by controlling the supply temperature of the supply water by mixing a part of the supply water to be returned and the supply water supplied, it is possible to cool by supplying cold water at a safe calculated temperature at the dew point.

11 is a view showing a combined operation of the radiation system 100 and the dehumidification air conditioner 200 according to the present invention, the operating range (Diff2) of the radiation system (100, RAD) is the room temperature +2 than the set temperature When the temperature rises, the operation is started and the operation may be set to be stopped when the temperature falls -1 ° C below the set temperature, and the operating range Diff1 of the dehumidification and air conditioning apparatus 200 (AHU) is + When the temperature rises by 3 ° C., the operation may be started and the operation may be stopped when the temperature is + 2 ° C. higher than the set temperature. The dehumidification and air conditioning apparatus 200 performs an auxiliary cooling function together with an indoor dehumidification action.

The operation of the radiation system 100 and the dehumidification and air conditioning apparatus 200 shown in FIG. 11 is controlled in a range in which the room temperature satisfies the set temperature ranges Diff1 and Diff2 based on the set temperature, and the characteristic environment of each room. According to the present invention, the auxiliary cooling may be controlled to represent a room having the largest range among the environments of each detected room including the margin coefficient value.

Accordingly, the maximum load operation in which the radiation system 100 and the dehumidification air conditioner 200 are operated simultaneously and the partial load operation in which the radiation system 100 and the dehumidification air conditioner 200 are partially operated may be performed according to each room environment. Can be.

The set temperature ranges Diff1 and Diff2 in which the radiation system 100 and the dehumidification and air conditioning apparatus 200 are operated apply a range of values calculated by repeated experiments, and set the values according to the environment (0.5 to 3 ° C.), and can be operated by adjusting the set value again when the environment characteristic is out of the range.

Referring to FIG. 12, the dehumidification and air conditioning apparatus 200 performs a combination of a dehumidification function, an auxiliary cooling function, a ventilation function, and an exhaust function.

The dehumidification function enables the indoor stable state to be realized through indoor humidity measurement and dew point temperature control. The auxiliary cooling function realizes the indoor set temperature by measuring indoor temperature and comparing with the set temperature. Measurement and comparison with the reference setting value to reach the appropriate environment, and the exhaust function is to operate the exhaust device to increase the indoor air to the appropriate environment when the indoor carbon dioxide concentration increases.

On the other hand, as a control step for coping with the additional variable environment in addition to the above-described technical control step, in consideration of the conditions that can be generated from the inside or outside to affect the indoor environment of the dehumidifying device 210 and the exhaust device 240 Interlocking control can be performed.

13 is an explanatory view showing a control operation range of the dehumidifier according to the present invention, and FIG. 14 is an explanatory view showing a control operation range of the dehumidifier and the exhaust device according to the present invention.

According to the conditions of the indoor environment, the basic operating conditions of the dehumidifying apparatus 210 may be operated at a relative humidity X (%), which is a high humidity state, based on the set humidity as shown in FIG. Operation stops at (%).

Further, interlocking control of the exhaust device 240 in the room is driven in the range shown in FIG. 14 in order to cope with a large increase in the humidity of the room and a sudden increase in the room humidity even after the operation of the dehumidifier 210.

The exhaust device 240 is not limited to the exhaust fan, but may be any exhaust device installed indoors such as a kitchen hood or a toilet exhaust fan in the room.

In the present invention, the surface dew condensation of the radiation panel 190 and the optimum operating range with the humidity control device are derived based on the derived result of the indoor floor or ceiling surface temperature as the room temperature and the humidity increase. The optimum range of Y (%) is based on controlling the operation in the range of ± 3%.

In addition, the range of interlocking control between the dehumidifier 210 and the exhaust device 240 must be activated within a safe range for the surface condensation of the radiation panel 190 installed indoors, and thus the operation (ON) and stop of the exhaust device 240 are performed. The control ranges of (OFF) EO (%) and EC (%) may be set to be operated in a range of ± 2% based on X (%) which is the start time of operation of the dehumidifier 210.

Operation control of the dehumidifier 210 is performed on the basis of the priority of indoor dehumidification, and the ventilation device by sensing the carbon dioxide concentration in the general room with the partial load operation of the dehumidifier 210 and the radiation system 100 in the room. By performing the operation of the 220 in parallel, in response to a sudden increase in humidity in the room, it is integrated with the exhaust device 240 that is already installed, thereby comprehensively controlling operation.

15 is a conceptual diagram of a comprehensive interlocking control of the main controller according to the present invention. The main controller 300 collectively controls the radiation system 100, the dehumidification air conditioning apparatus 200, and the exhaust system 240. In addition, the above-mentioned overall operation control is the damper (231, 232, 233) control operation function (see Fig. 18) of the air conditioning distributor 230 to control this, the control of the supply valve (V1 ~ V7) of the feed water and the three-way mixing valve ( Basically, operations such as proportional control by adjusting the opening degree of 130) are basically included.

The overall operation of the dehumidifying device 210, the ventilation device 220 and the exhaust device 240 as described above can be sequentially controlled to the environmental change of the indoor humidity, but the indoor humidity in the case of a specific situation in which the humidity rapidly rises indoors Dehumidifier 210 does not operate as shown in FIG. 16 even if the humidity increases until the relative humidity of the room detected by the sensor 312 reaches a range of the set humidity + 3%, which is a general control range. .

Therefore, in addition to the control method of general humidity, a control method for preventing the risk of condensation by detecting a sudden rise in humidity and preventing indoor diffusion and rise of humidity in advance is required. Conditional expression for starting the operation of the dehumidification and air conditioning apparatus 200 is shown.

Here, Calculation (AHU) represents the operation start condition of the dehumidification and air conditioning apparatus 200, H1 represents a measured value of indoor humidity at the reference point, H2 represents a measured value of indoor humidity measured 5 seconds after the reference point, and % Represents the set rate of humidity change.

In the room where the humidity is measured in units of a set time (5 seconds) according to the above formula, and the change in the indoor humidity measured by the unit of time is equal to or greater than the set humidity change rate (2%), the radiation system 100 At the same time, the operation of the dehumidification and air conditioning apparatus 200 is operated in a forced dehumidification mode that performs only dehumidification and ventilation and auxiliary cooling functions.

Here, the forced dehumidification mode refers to the control to operate only the dehumidification air conditioner 200 and cut off the supply water supplied from the radiation system 100 in the room in which the humidity is detected to rise rapidly, and the indoor load generated at this time is the dehumidification air conditioning. The device 200 takes charge of the operation.

The indoor humidity is measured in units of a set time (1 second) during the operation of the forced dehumidification mode, and there is no increase in the indoor humidity as a result of the measurement of the indoor humidity, and the indoor humidity is set higher than the indoor humidity measured when the forced dehumidification mode is executed. When the humidity decreases below the rate of change (-2%), the dehumidification mode is changed from the forced dehumidification mode to the normal dehumidification mode. In this case, when the dew point calculation determines that the safety state is free from the risk of dew condensation, the radiant cooling of the copy system 100 is performed. Operation is performed in parallel with the operation of the dehumidification and air conditioning apparatus 200.

Referring to the graph of FIG. 16, when the general humidity is increased, the humidity can be controlled within a range of approximately ± 2% from the set humidity value. However, when the humidity rapidly rises under the set humidity, the humidity rises by about 6% or more. Only dehumidifier 210 can be seen to operate. Therefore, it is necessary to detect the prediction of the sudden rise of humidity, and to this end, the maximum range of humidity increase according to the detection time of the indoor humidity sensor 312 is determined and recognized as a forced dehumidification mode in addition to the general dehumidification mode, so that the dehumidification and air conditioning apparatus 200 operates. If possible, additional control method is configured.

Through several empirical experiments, the range of humidity increase within the detection time of the indoor humidity sensor 312 was derived as 2% per 5 seconds as the safety range, and the control logic for this immediately detects the increase of humidity in addition to the general humidity control logic. It is configured to give priority control to operate.

That is, in the general situation, the maximum humidity change was 0.8% per 5 seconds, and if the humidity rises by 2% or more per 5 seconds, it should be regarded as the occurrence of external humidity, and corresponding operation is necessary. Therefore, the additional humidity control logic as described above is an emergency operation rather than a control in a general situation, it is possible to immediately and safely control to implement the environment set by the user in any environment change.

FIG. 17 schematically shows the equipment to which the radiation system 100 and the dehumidification air conditioner 200 are supplied to each room, and FIG. 18 is supplied to each room from the air conditioning distributor 230 connected to the ventilator 220. The installation structure of the dampers (231, 232, 233) to control the flow of air independently of each other, the present invention is characterized in that the radiation cooling and heating and dehumidification air conditioning action using the radiation system 100 in response to the environmental changes of each room is individually controlled It is done.

Conventionally, the radiation system receives the signal value according to the change of the indoor environment of each room and performs the supply water temperature and the dehumidification and air conditioning control operation based on the maximum value, but the actual living environment has different load characteristics and various variables occur in each room. Can be.

Therefore, there is a need for a device that can control the dew point according to each room environment change, but the existing system does not suggest such a method, and chooses a method of operation control based on the environment of the room having the worst condition. Doing. However, such a conventional system has a problem in that when a risk of condensation occurs due to a sudden change in the indoor environment in one room, the room is recognized as a representative value and the driving is performed to affect the other rooms together.

In order to solve this problem, the present invention solved this problem by installing a dew point control device in each room as a double safety device to more stably solve the problem of condensation that may occur in each of the independent rooms.

The dew point control device is composed of an indoor humidity sensor 312 and an analog data communication board. The indoor humidity sensor 312 is installed on the radiation panel of the condensation occurrence area in the room to detect whether dew point is generated, and the analog data communication board detects the analog (4-20 mA) signal detected by the indoor humidity sensor 312. This is converted to RS485 communication, the converted signal is transmitted to the main controller 300 through the room controller 310 installed in each room.

In a small room, it can be controlled by one condensation sensor 191, but when the size of the room is large or there are several multifunctional devices in one space such as a living room, it is necessary to subdivide the area to measure humidity and condensation sensor. It is necessary to install 191.

The condensation according to the detection method of the condensation sensor 191 may be classified into 1) a humidity sensing method and 2) a mechanical contact method.

1) The humidity detection method detects the actual humidity generated in the space where the condensation sensor 191 is installed, and if the detected humidity is equal to or higher than the set humidity, the analog signal is directly transmitted to the main controller 300 or analog data communication is performed. As a method of converting and transmitting to RS485 communication through the board, the installation position of the condensation sensor 191 is an area or humidity in which the ceiling or the corner of the room and the ventilation that can be different from the humidity in the indoor air is not properly made It is desirable to adopt a position where it can rise rapidly, and by applying the humidity sensing method, it is possible to perform a function to prevent the risk of condensation due to the increase in humidity.

2) The mechanical contact method is a switch method of dry contact in which no voltage is applied to an electric circuit in general. When the condensation sensor 191 is attached to the radiation panel 190, radiation is generated by heat conduction. The surface temperature of the panel 190 and the surface temperature of the dew condensation sensor 191 are formed at a similar temperature, and even when minute condensation occurs on the surface of the dew condensation sensor 191 according to the change of humidity around the panel 190, it is detected with high accuracy. As a method of transmitting a signal to the controller, it is possible to prevent condensation due to an error of the moisture detection control method of the humidity sensing method in advance, and to prevent unexpected condensation that may occur in the set safety humidity range in advance. Performs a double failsafe function.

The set humidity range of the humidity detection method among the detection methods of the condensation sensor 191 refers to a value derived through a plurality of experiments, and in the present invention, the set humidity range is controlled based on a relative humidity of 70%. As a result of measuring the surface temperature and humidity change value of the radiation panel 190 according to the supply of water in the summer summer environment, when the relative humidity is 70% or more, the risk of condensation or fine condensation is generated. It is basically based on controlling the dew point signal within the range of ± 3%. The range of ± 3% set here can be set to 1 to 5% variably depending on the application site, and the exemplary value is designated as ± 3% in the present invention.

In addition, the mechanical contact method of the condensation sensor 191 performs the function of sending an immediate signal when the actual condensation occurs, even after the condensation risk environment is released, the continuous signal is affected by the number of condensation generated in the condensation sensor 191 Since the transmission is maintained, the mechanical contact method is considered to be suitable for the main purpose of the double safety device. Therefore, it is optimal to apply the two contact types in combination except where the independent use is necessary. It is preferable to prevent condensation.

In the present invention, if it is detected that there is a risk of condensation from the condensation sensor installed in any one of the condensation sensor 191 installed in each room in the normal dew point control operation state, without immediately controlling the temperature of the main feed water, Implement the primary control to cut off only the water supply to the room where there is a risk of condensation, and start the dehumidification and air conditioning device 200 to lower the increased temperature or humidity in the room where the danger occurs. Create under normal safe environmental conditions. For this control, the dehumidification ventilation function is performed in each room by independently controlling the opening and closing of the dampers 231, 232, and 233 provided in the air conditioning distributor 230 installed at the front end of the diffuser 225 in each room.

Through the comprehensive control of the above-mentioned equipment, it is possible to provide a comfortable indoor environment while maintaining the temperature environment set by the occupants, and to operate only the equipment necessary for indoors by the optimal control operation, and to provide cooling and heating by radiant heat of the radiation system. By performing the energy consumption can be reduced, it is possible to maximize the cooling and heating and air conditioning efficiency by the interlocking operation of the existing equipment installed indoors.
