Definitions

  • the present invention relates to a control device for an air conditioning system concurrently using an air conditioner and a blower such as an electric fan.
  • a conventional control device for an air conditioning system concurrently using an air conditioner and a blower is provided with a switch for changing a target temperature of the air conditioner, as shown in Japanese Patent Application Examined Publication No.S60-29855.
  • the switch raises the target temperature by a given degree, and simultaneously a driving switch of an electric fan is turned on in synchronization with the switch.
  • a driving switch of an electric fan is turned on in synchronization with the switch.
  • the target temperature of the air conditioner is shifted to be a given amount higher. Therefore, there is a problem that comfortableness of the air condition may be impaired.
  • An object of the present invention is to provide a control device for an air conditioning system that can always and compatibly provide comfortableness and energy saving by shifting a target temperature of an air conditioner by an optimal shift amount responsive to a room temperature and operation-condition-settings for the air conditioner and a blower, during a concurrent operation of the air conditioner and the blower.
  • a control device in accordance with the present invention comprises the following elements:
  • the target temperature shifting means determines the shift amount of the target temperature to be smaller with higher target temperature. Thus, even when the target temperature set by a user changes, coolness feeling can be kept constant.
  • the target temperature shifting means determines the shift amount of the target temperature to be larger with larger wind quantity of the blower.
  • the control device in accordance with the invention further has a room temperature detecting means.
  • the target temperature shifting means shifts the target temperature to be higher after the room temperature reaches the proximity of the target temperature.
  • the target temperature is not shifted to be higher until the room temperature reaches the proximity of the target temperature, and therefore, the user can feel comfortable in a short time.
  • the control device in accordance with the first invention further has an air-conditioner wind quantity setting means for setting wind quantity of the air conditioner, and the target temperature shifting means does not shift the target temperature when the wind quantity of the air conditioner is larger than a given value and the wind quantity of the blower is smaller than a given value.
  • the target temperature is not shifted to be higher when coolness felt by the user is not improved with the operation of the blower.
  • Fig. 1 shows a block diagram of a control device for an air conditioning system in accordance with the present invention.
  • operating means 1 comprises the following elements:
  • Operation selecting means 2 has respective switches for turning on or off of the air conditioner and turning on or off of the blower such as an electric fan or a ceiling fan, and is used for selecting a single operation of either the air conditioner or the blower or a concurrent operation of the air conditioner and the blower.
  • Air-conditioner temperature setting means 3 is to feed and set a target temperature of the air conditioner
  • air-conditioner wind quantity setting means 4 is used by the user to feed and set a wind quantity of the air conditioner
  • blower wind quantity setting means 5 is to feed and set a wind quantity of the blower.
  • Room temperature detecting means 6 has a room temperature sensor at an air-conditioning inlet and detects a room temperature.
  • Target temperature shifting means 7 - installed in the air conditioner - determines a shift amount by which the target temperature is shifted based on each operation condition setting information of operation selecting means 2, air-conditioner temperature setting means 3, air-conditioner wind quantity setting means 4, and blower wind quantity setting means 5. The information discussed above is transmitted from operating means 1. In addition to that information, the room temperature information from the room temperature detecting means 6 is also used for determining the shift amount. Further, the means 7 changes the target temperature set by air-conditioner temperature setting means 3 by shifting it by the determined shift amount.
  • Air-conditioner capacity control means 8 is used for controlling capacity of the air conditioner so that the room temperature detected by room temperature detecting means 6 is equal to the target temperature set by air-conditioner temperature setting means 3 and target temperature shifting means 7.
  • Air-conditioner wind quantity control means 9 controls number of revolutions of a fan-motor of the air conditioner to control wind quantity of the air conditioner to be equal to the wind quantity set by air-conditioner wind quantity setting means 4.
  • Blower wind quantity control means 10 controls number of revolutions of a fan-motor of the blower to control wind quantity of the blower to be equal to the wind quantity set by blower wind quantity setting means 5.
  • Fig.2 is a time-based diagram showing a control operation during cooling in accordance with the embodiment.
  • air-conditioner capacity control means 8 controls the capacity of the air conditioner so that the room temperature detected by room temperature detecting means 6 equals to target temperature Ts1 fed by air-conditioner temperature setting means 3.
  • the wind quantity of the air conditioner is controlled by air-conditioner wind quantity control means 9 so as to equal to wind quantity setting Va2 fed by air-conditioner wind quantity setting means 4.
  • the room temperature before an operation of the air conditioner drops time-dependently and stabilizes at target temperature Ts1.
  • the blower is turned on with operation selecting means 2, and thereby the air conditioner and the blower are concurrently operated.
  • the wind quantity of the blower is controlled by blower wind quantity control means 10 so as to equal to wind quantity Vf3 fed by blower wind quantity setting means 5.
  • target temperature Ts1 during the single operation of the air conditioner is shifted to be + ⁇ T2°C higher, i.e. the target temperature is changed to Ts1+ ⁇ T2 for the concurrent operation with the blower, by target temperature shifting means 7.
  • Target temperature shifting means 7 determines the shift amount of the target temperature, based on a prerecorded relation of optimal shift amount of the target temperature to the blower wind quantity setting, in which the shift amount of the target temperature increases at the greater blower wind quantity setting. In other words, wind speed for the user becomes higher with larger wind quantity of the blower, and this increases coolness feeling. Therefor, the user feels the same coolness even when the target temperature is set higher. Thus, regardless of a level of the blower wind quantity setting during the concurrent operation with the blower, comfortable coolness feeling equivalent to that during the single operation of the air conditioner can be always maintained.
  • the shift amount of the target temperature is set at 0°C by target temperature shifting means 7, in other words, the target temperature setting is returned to target temperature Ts1 during the single operation of the air conditioner and is prevented from being shifted. This is based on a rule that the shift amount of the target temperature is set at 0°C when the air-conditioner wind quantity setting is larger than a preset value Va3 and the blower wind quantity setting is smaller than a preset value Vf1.
  • Fig.4 is a time-based diagram showing another example of control operations during cooling in accordance with the embodiment.
  • air-conditioner capacity control means 8 controls the capacity of the air conditioner so that the room temperature detected by room temperature detecting means 6 equals to target temperature Ts3 fed by air-conditioner temperature setting means 3.
  • the wind quantity of the air conditioner is controlled by air-conditioner wind quantity control means 9 so as to equal to wind quantity setting Va2 fed by air-conditioner wind quantity setting means 4.
  • the wind quantity of the blower is controlled by blower wind quantity control means 10 so as to equal to wind quantity setting Vf3 fed by blower wind quantity setting means 5.
  • target temperature shifting means 7 sets the shift amount of the target temperature at null i.e. not to shift target temperature setting Ts3 during the single operation of the air conditioner and keep the setting until the room temperature reaches target temperature setting Ts3 and stabilizes.
  • target temperature Ts3 is shifted to be + ⁇ T3°C higher, i.e. the target temperature is changed to Ts3+ ⁇ T3, by target temperature shifting means 7.
  • the target temperature is not shifted higher until the room temperature approaches the target temperature and stabilizes, and comfortableness can be prevented from being impaired in starting the operation, because a high priority is given to more rapidly providing the user with sufficient coolness feeling.
  • the user is assumed to turn off the blower with operation selecting means 2, and simultaneously increase the target temperature setting from Ts3 to Ts4 with air-conditioner temperature setting means 3.
  • the shift amount of the target temperature setting is set at null by target temperature shifting means 7, and target temperature is changed from Ts3+ ⁇ T3 to Ts4.
  • the shift amount of the target temperature is set at + ⁇ T4 by target temperature shifting means 7, and target temperature is changed from Ts4 during the single operation of the air conditioner to Ts4+ ⁇ T4 during the concurrent operation with the blower. Comparing the present target temperature Ts4 during the single operation of the air conditioner with the previous target temperature Ts3, Ts3 is lower than Ts4, and therefore the shift amount of the target temperature is set so that + ⁇ T3 is larger than + ⁇ T4.
  • target temperature shifting means 7 determines the shift amount of the target temperature based on a prerecorded relation of the shift amount of the target temperature during the concurrent operation with the blower to the target temperature during the single operation of the air conditioner, in which the shift amount of the target temperature during the concurrent operation with the blower is smaller with larger target temperature during the single operation of the air conditioner.
  • This relation is based on human's sensing characteristic for temperature that effect for increasing the coolness feeling is smaller with higher room temperature even for same wind speed increment. Therefore, during the concurrent operation with the blower, an optimal shift amount of the target temperature according to levels of the target temperature is set, and comfortable coolness feeling can be always maintained.
  • a control device of the present invention for an air conditioning system can always and compatibly provide comfortableness and energy saving by shifting the target temperature of the air conditioner by the optimal shift amount responsive to a room temperature and operation condition settings for the air conditioner and the blower, during the concurrent operation of the air conditioner and the blower.
