Embodiment
Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
As depicted in figs. 1 and 2, according to electric heater component control method of the present invention, electric heater component comprises organizes heater more, and the method comprises: step S1: the leaving air temp detecting electric heater component; Step S2: leaving air temp and preset temperature condition are contrasted; Step S3: when leaving air temp does not meet preset temperature condition, controls the open and-shut mode of the part group heater in many group heaters.The present invention organizes heater by making electric heater component comprise more, and when leaving air temp does not meet preset temperature condition, the open and-shut mode of the part group heater in many group heaters is controlled, improve the stability of leaving air temp, avoid standard-sized sheet or complete shut-down in prior art to cause leaving air temp sometimes hot and sometimes cold, improve and heat comfort level.
Particularly, preset temperature condition comprises protection temperature and recovery temperature, when leaving air temp is greater than protection temperature, closes the part group heater in many group heaters, namely when temperature is higher than protection temperature, starts packet protection, prevents temperature from suddenly reducing; When leaving air temp is less than recovery temperature, opens the part group heater in many group heaters, namely when temperature is lower than recovery temperature, start packet recovery, prevent temperature from suddenly raising, thus prevent leaving air temp sometimes hot and sometimes cold.As required, each one group of heater of opening or closing in many group heaters can be adopted, namely regulate by group, certainly, also can Primary regulation several groups, as 2 groups, 3 groups etc.
Further; when leaving air temp does not meet preset temperature condition; after the open and-shut mode of the part group heater in many group heaters is controlled; requirement is reached in order to ensure leaving air temp; also need to repeat above-mentioned steps S1 to S3; until the leaving air temp detected meets preset temperature condition; or institute's having heaters standard-sized sheet or complete shut-down are (namely when leaving air temp is greater than protection temperature; and each group heater cuts out all in many group heaters; or; when leaving air temp is less than recovery temperature, and in many group heaters, each group heater is opened all).
Preferably, control method of the present invention also comprises delaying step, namely when leaving air temp does not meet preset temperature condition, after the open and-shut mode of the part group heater in many group heaters is controlled, and before repeating above-mentioned steps S1 to S3, wait for and preset delay time, also after namely often closing or opening a part of heater, time delay Preset Time, Deng leaving air temp stable after, carry out next step again to regulate, the regulating error preventing leaving air temp instability from causing, guarantees the reliability regulated.
More specifically, in order to ensure leaving air temp stability, prevent frequent adjustment, protection temperature comprises protection and starts temperature T1 and protect to stop temperature T2, wherein, and T1 >=T2.Shown in composition graphs 1, when leaving air temp is greater than protection beginning temperature T1, and circulation closes heater by group, until the leaving air temp detected is less than or equal to protection stop temperature T2, or all closes in institute's having heaters.
Similarly, recovery temperature comprises recovery beginning temperature T3 and recovers to stop temperature T4; Wherein, T3≤T4.Shown in composition graphs 2, when leaving air temp is less than recovery beginning temperature T3, open the part group heater in many group heaters; And the heater by group that circulates, recover to stop temperature T4 until the leaving air temp detected is more than or equal to; Or each group heater is opened all in many group heaters.
Particularly, composition graphs 1 and Fig. 2 illustrate the adjustment process of control method of the present invention.
As shown in Figure 1, when leaving air temp exceedes protection beginning temperature T1, air-conditioner controller is action before thermal protector, and controller first cuts out wherein one group of heater, makes always to heat power drop, thus reduces leaving air temp.If now leaving air temp still exceedes protection stopping temperature T2, after time delay t1, then controller cuts out next group heater again, stops temperature T2 or institute's having heaters to close until leaving air temp is less than protection.
Further, as shown in Figure 2, when the outside cause causing leaving air temp too high is eliminated, when causing leaving air temp to start temperature T3 lower than recovery, controller first starts wherein one group of heater, and gross power is increased, thus improves leaving air temp.If now leaving air temp is still less than recovery stopping temperature T4, after time delay t2, then next group heater restarted by controller, recovers to stop temperature T4 or all electric heating to open until leaving air temp is greater than or equal to.Time delay t1 and time delay t2 can be equal, also can not wait.
Present invention also offers a kind of electric heater component control device corresponding with preceding method, electric heater component comprises organizes heater more, and device comprises: detection module, for detecting the leaving air temp of electric heater component; Comparison module, contrasts leaving air temp and preset temperature condition; Control module, for when leaving air temp does not meet preset temperature condition, controls the open and-shut mode of the part group heater in many group heaters.Namely organize heater by making electric heater component comprise more, and when leaving air temp does not meet preset temperature condition, the open and-shut mode of the part group heater in many group heaters is controlled, improve the stability of leaving air temp, avoid standard-sized sheet or complete shut-down in prior art to cause leaving air temp sometimes hot and sometimes cold, improve and heat comfort level.
Preferably, preset temperature condition comprises protection temperature and recovery temperature; Control module comprises: the first submodule, during for being greater than protection temperature when leaving air temp, closes the part group heater in many group heaters; Second submodule, for when leaving air temp is less than recovery temperature, opens the part group heater in many group heaters.Namely the first submodule realizes temperature protection, and the second submodule realizes stable recovery.
Further; control device also comprises; judge module is used for when leaving air temp does not meet preset temperature condition; after the open and-shut mode of the part group heater in many group heaters is controlled; the open and-shut mode of circulation to the part group heater in many group heaters controls; until the leaving air temp detected meets preset temperature condition; or; when leaving air temp is greater than protection temperature; and each group heater cuts out all in many group heaters; or when leaving air temp is less than recovery temperature, and each group heater is opened all in many group heaters.
Preferably, control device also comprises time delay module, time delay module is used for when leaving air temp does not meet preset temperature condition, after the open and-shut mode of the part group heater in many group heaters is controlled, before the open and-shut mode of circulation to the part group heater in many group heaters controls, wait for and preset delay time.I.e. every circulation primary, waits for and presets delay time, wait leaving air temp stable after start again to detect judgement next time.
As can be seen from the above description, the above embodiments of the present invention achieve following technique effect:
According to electric heater component control method of the present invention and control device, comprise by making electric heater component and organize heater more, and when leaving air temp does not meet preset temperature condition, the open and-shut mode of the part group heater in many group heaters is controlled, improve the stability of leaving air temp, avoid standard-sized sheet or complete shut-down in prior art to cause leaving air temp sometimes hot and sometimes cold, improve and heat comfort level.
