The settable maximum heating supply set temperature TmaxW is set to "70 to 90 ° C" and the settable maximum heating indoor set temperature TmaxR is set to "35 to 45 ° C".

Reference numeral 11 denotes an arithmetic unit provided in the control device 1, 4 denotes a flame detection device, 5 denotes a blowing fan drive device, 6 denotes a gas supply drive device, and 9 denotes an indoor temperature detection sensor.

The operation and effect of the method of the present invention having the above steps will be described as follows.

First, in the boiler control device 1 to which the method of the present invention is applied, the output signal of the temperature regulating device 7 or the like is continuously input, and if the heating operation enters the "on" mode, (S1) through a circulation pump (not shown) to circulate the heating water into the heating pipe.

If the ignition condition according to the general heating is satisfied (for example, the heating supply temperature Tout or the room temperature is lower than the heating supply set temperature TsetW), it is determined whether or not the ignition condition according to the general heating is satisfied (S2) (S3), the blower fan driving device (5) and the gas supply driving device (7) are driven and the igniter is operated to perform the heating combustion (S3) The room temperature detected by the indoor temperature detecting sensor 8 with respect to the heating set temperature TsetW is compared and the general heating operation is performed (S4).

Thereafter, the control device 1 determines whether the user has turned on the heating rapid operation switch 71 provided in the temperature control device 7 (S5) It is determined whether the heating operation mode desired by the user is the heating water temperature control mode in order to check whether the heating operation control mode is the heating water temperature control mode or the indoor temperature detection mode (S6 ).

As a result of checking the heating operation mode desired by the user, if the heating water temperature control mode is selected, the heating supply set temperature TsetW already determined in the normal heating operation is supplied to the storage device 12 in the control device 1 as the initial heating supply set temperature TsetWS (S7) as well as changing the heating supply set temperature TsetW to a settable maximum heating supply set temperature TmaxW (for example, "70 to 90 deg. C") so as to control the calorie quantity according to the maximum rapid heating operation (S8).

The control device 1 determines whether or not the predetermined maximum rapid heating operation operation time A has elapsed (S9), and if the maximum rapid heating operation operation (S9) If the time A has not elapsed, it is determined whether the heating supply temperature Tout is higher than or equal to the value of the heating supply set temperature TsetW × the first multiple T1.

Here, the maximum rapid heating operation operation time (A) is set to "20 to 30 minutes", which depends on the atmospheric temperature and the heat insulating performance of a space requiring heating, If the maximum rapid heating operation operation time (A) is set to be shorter than 20 minutes, the user can not cancel the operation until the temperature is changed. The performance of the rapid heating operation is deteriorated. If it is set longer than "30 minutes ", unnecessary heating supply occurs such that the temperature of the space requiring the heating rises excessively, and the digestion time becomes long, The maximum rapid heating operation operation time (A) is set to "20 to 30 minutes" in the present invention.

In addition, the first drainage T1 is set to a ratio of 0.8 to 0.9 in proportion to the amount of heating according to the heating operation, that is, a multiple of the heating supply set temperature for confirming that the temperature is close to the heating supply set temperature TsetW. If the first drainage T1 is set to less than 0.8, the heating water temperature may be stabilized before proceeding to the next step, so that it may be extinguished before reaching the heating supply set point temperature, If it is set to more than "0.9", it is not possible to maintain a state in which it is impossible to proceed to the next step when the temperature is controlled to be lower than the heating supply set temperature according to the characteristic of the heat quantity control system. In the present invention, Is set to "0.8 to 0.9 ".

On the other hand, when the controller 1 determines whether the heating supply temperature Tout is higher than or equal to the heating supply set temperature TsetW × the first multiple T1, the heating supply temperature Tout is lower than the heating supply temperature Tout (TsetW) - the heating return temperature (Tin) to determine whether the heating pipe is sufficiently circulated and becomes thermal equilibrium if the heating supply set temperature (TsetW) is higher than or equal to the first set value (T1) ) Is determined to be lower than or equal to the predetermined temperature difference? T for a predetermined second time B or more (S11).

Here, the determined temperature difference? T is set to "15 to 25 占 폚" as the limit temperature difference between the heating supply set temperature TsetW and the heating return temperature Tin, 15 ° C ", even though the supply of the heating water is sufficient, the condition of heating is not satisfied due to the influence of the minimum amount of heat of the boiler and the circulation flow rate of heating, so that the heating supply temperature rises and there is a possibility of high cut or overheating If it is set at a high temperature exceeding "25 DEG C ", it can be easily satisfied at a low minimum heating supply set temperature. As a result, the heating performance may be lowered due to extinguishing in a state where the heating is not sufficiently supplied at the initial stage. The limit temperature difference? T between the heating supply set temperature TsetW and the heating return temperature Tin is set to 15 to 25 占 폚.

The predetermined second time (B) is a time for determining the temperature stabilization by circulating the entirety of the heating pipe two to three times. It is determined by the number of distributors and the number of distributors If the second time (B) is set to be less than "5 minutes", it is set to "5 ~ 15 minutes" It may be extinguished before reaching the heating supply set temperature (TsetW), resulting in deterioration of the heating performance, and if it is set to exceed "15 minutes", transfer to the next step, (B) is set to "5 to 15 minutes" in the present invention.

On the other hand, if the controller 1 determines that the value of the heating supply set temperature TsetW - the heating return temperature Tin is lower than or equal to the determined temperature difference T for a predetermined second time B or more (S11), if the value of the heating supply set temperature (TsetW) - the heating return temperature (Tin) is lower than or equal to the predetermined temperature difference (T) for a second predetermined time (B) or more, It is determined that the heat is sufficiently circulated and the heat balance is performed, and it is determined whether the current heat amount is smaller than or equal to the boundary heat amount Q (S12).

If it is determined that the current heat quantity is less than or equal to the boundary heat quantity Q as a result of S12, if it is determined that the current heat quantity is smaller than or equal to the boundary heat quantity Q, it is determined that the heating is sufficient and the rapid heating operation is canceled ).

Further, in the control device 1, after the rapid heating operation is canceled because the current heat quantity is smaller than or equal to the boundary heat quantity Q, the control device 1 judges again whether it is the heating water temperature control mode (S14) The heating supply control temperature TsetW is changed to the first heating supply control temperature TsetWS previously stored in the storage device 12 in step S15 and if the heating water temperature control mode is not set The heating indoor set temperature TsetR is changed to the initial heating indoor set temperature TsetRS previously stored in the storage device 12 (S16), and then the heating operation is controlled to the general heating operation mode S17).

On the other hand, if it is determined that the ignition condition according to the general heating is satisfied in the controller 1 (S2), if the ignition condition according to the general heating is not satisfied (No in S2, for example, (S18) and then enters the heating standby mode (S19). Then, the user sets the heating mode of the heating device (7) It is determined whether the rapid operation switch 71 is turned " on "(S20).

As a result of checking the state of the heating rapid operation switch 71, if the heating rapid operation switch 71 is in the "off" state, the process returns to the step S2 of determining whether the ignition condition according to the normal heating is satisfied, (S22), the heating water is circulated to the heating pipe (S22), and the heating water temperature control mode is determined (S6 ), And repeats the subsequent steps.

If it is determined in step S6 that the controller 1 is in the heating water temperature control mode in the initial stage of heating operation, the controller 1 determines that the heating water temperature control mode is not the heating water temperature control mode (No in S6) Stores the previous heating indoor temperature set value TsetRS stored in the heating indoor temperature set value TsetRS as the heating indoor temperature set value TsetR at step S23 and sets the heating indoor temperature setting TsetR at the highest heating indoor temperature setting temperature TmaxR 35 to 45 占 폚) (S24) and changes the heating supply set temperature TsetW to the settable maximum heating supply set temperature TmaxW (S25).

Subsequently, it is judged whether the heating room temperature Troom is lower than the heating room set temperature TsetR (S26). If the heating room temperature Troom is lower than the heating room set temperature TsetR, the determined maximum rapid heating driving operation time (A) has elapsed (S9), and repeats the subsequent steps.

However, if the heating room temperature Troom is equal to or higher than the heating indoor set temperature TsetR, it is recognized that the heating is sufficiently performed and extinguished (S27), the operation of the circulating pump is stopped (S28) When it is determined that the heating operation time A has elapsed, the process returns to the step S13 to release the rapid heating operation as in the case where the maximum rapid heating operation operation time A has elapsed (Yes in S9).

On the other hand, as described above in the control device 1, when the value of the heating supply set temperature TsetW - the heating return temperature Tin is lower than or equal to the predetermined temperature difference? If it is determined that the value of the heating supply set temperature TsetW -The heating return temperature Tin is lower than or equal to the predetermined temperature difference T as a result of the determination at step S11, (S12). If the current heat quantity is higher than the boundary heat quantity Q (No in S12), it is determined that the heating supply temperature Tout is lower than or equal to the heating supply set temperature (TsetW) times the second multiple (T2) (S29).

Here, the second drainage T2 is set to 1.1 to 1.3 as a multiple of the heating supply set temperature TsetW for determining the high cut. At this time, the second drainage T2 is set to be less than 1.1 The heating performance may be deteriorated before the heating is smoothly supplied, and if it exceeds "1.3", unnecessary combustion may occur at a temperature higher than the heating supply set temperature (TsetW) or the product may be overheated In the present invention, the second multiple T2 is set to "1.1 to 1.3 ".

It is determined whether the heating supply temperature Tout is higher than or equal to the heating supply set temperature TsetW times the second multiple T2 in the control device 1 as described above. ) Is higher than or equal to a value obtained by multiplying the heating supply set temperature (TsetW) by a second multiple (T2), it is recognized that the heating is sufficiently performed by the user at the desired temperature in the space, the operation of the circulating pump is maintained, (S30).

In the control device 1 in which the burner is extinguished (S30), the heating supply temperature Tout and the heat return temperature Tin are set to the heating supply set temperature TsetW × the third multiple T3, (S31). If any of the heating supply temperature (Tout) or the heating water return temperature (Tin) is lower than the heating supply set temperature (TsetW) multiplied by the third multiple (T3) (No in S31), the heating combustion is performed again (S32).

However, if both the heating supply temperature Tout and the heating return temperature Tin are higher than or equal to the heating supply set temperature TsetW times the third heating cycle T3 (Yes in S31) It is determined whether or not the third time (C) required for three cycles of circulation has elapsed (S33).

Whether or not the third time C has elapsed after the heating supply temperature Tout and the heat return temperature Tin are both higher than or equal to the value of the heating supply set temperature TsetW times the third multiple T3 (S33). If the third time C has not elapsed (No in S33), it is determined whether the predetermined maximum rapid heating operation operation time A has elapsed (S34) and the maximum rapid heating operation operation time A (No in S34), it is judged whether the heating supply temperature Tout and the heat return temperature Tin are higher than or equal to the values of the heating supply set temperature TsetW and the third multiple T3 S31) and repeats the subsequent steps.

However, if the third time C elapses (Yes in S33) or the maximum rapid heating operation operation time A has elapsed (Yes in S34), the operation of the circulation pump is also stopped (S35), and the rapid heating operation is terminated The process returns to step S13 to complete the heating operation completely.

In this case, the third drainage T3 is set to a value of "0.5 to 0.7" which is a multiple for determining the heating water temperature for preventing premature fire extinguishing. This should be set in consideration of the minimum consumption amount of the boiler, T3) is set to less than "0.5", it is possible to prevent premature fire extinguishment after re-ignition, but the time for supplying the heating of the space requiring the heating is delayed, resulting in deterioration of the heating performance. There is a problem that the durability of the boiler deteriorates due to frequent premature fire extinguishment. In the present invention, the third drainage T3 is set to "0.5 to 0.7".

The third time (C) is a time required for heat exchange between the heating water column and the heating pipe in order to circulate the heating pipe two to three times in total to prevent repeated digestion. 5 to 15 minutes "in consideration of the fact that the length of piping per unit length of the distributor and the distributor is maximum 150 m depending on the maximum heating value of the boiler, and the third time (C) is shortened to less than" 5 minutes " There is a problem that the heating performance is deteriorated due to insufficient heating in a space requiring heating, and when the heating time is set to a time exceeding "15 minutes" dmf, the temperature rises in a space requiring heating, There is a problem that unnecessary energy loss and noise are generated by continuously operating the circulation pump in a state where the temperature of the heating water of the piping does not fall. In the present invention, It is set to (C) in "5 ~ 15 minutes".

On the other hand, when the control device 1 determines whether the heating supply temperature Tout is higher than or equal to the heating supply set temperature TsetW × the first multiple T1, The heating supply temperature Tout is lower than the heating supply set temperature TsetW by the first multiple T1 or the heating supply temperature Tout is lower than the heating supply set temperature TsetW by the second multiple T2 (S29), it is determined that the heating supply temperature Tout is lower than the value obtained by the heating supply set temperature TsetW times the second multiple T2 (No in S29) After the heating combustion is performed (S32) because the temperature Tout or the heating return temperature Tin is lower than the value obtained by the heating supply set temperature TsetW times the third multiple T3, (S36).

As a result of judging again whether or not the control device 1 is in the heating water temperature control mode (S36), if it is judged in the heating water temperature control mode (Yes in S36), it is judged whether or not the maximum rapid heating operation operation time If the heating room temperature Troom is not the heating water temperature control mode (No at S36; that is, if it is the indoor temperature detection mode), the heating indoor temperature setting TsetR (S26), and repeats the steps thereafter.

When the method of the present invention is applied to a boiler, it is possible to rapidly raise the temperature of the heating space where the temperature is greatly reduced at the initial stage of heating, so that the heating can be performed in an optimal state, If the temperature is saturated due to the rapid heating, it can be switched to the general heating, so that it is possible to prevent waste of energy due to unnecessary heating and also to greatly improve the reliability of the boiler itself due to its rapid heating control.
