PMV = 0 when comfort is emphasized using the MV index
The indoor temperature (or operating temperature) is calculated by inversely calculating the PMV formula and used as the indoor temperature set value. When both comfort and energy saving are considered, PMV = ± 0.5 indoor temperature (or operating temperature) In general,) is obtained by inversely calculating the PMV equation and used as the indoor set temperature.

【Example】

(Embodiment 1) FIG. 1 shows the configuration of a temperature setting device for an air conditioner, in which an indoor temperature sensor 1 for measuring the indoor temperature, and a sensation input means 2 for a resident to input a sensation with respect to the indoor temperature at that time. Is installed. The indoor set temperature calculation means 3 calculates the indoor set temperature from the indoor temperature measurement value measured by the indoor temperature sensor 1 and the sensible value input by the sensible feeling input means 2, and transmits it to the air conditioner 4. The air conditioner 4 keeps the indoor temperature at a desired value based on the indoor set temperature transmitted from the indoor set temperature calculation means 3.

FIG. 2 shows an example of the sensation input means 2.
As shown in this figure, there are five types of input buttons, "hot", "slightly hot", "comfortable", "slightly cold", and "cold", which are available to the resident depending on their experience. And press any button. A sensation value dTv is set for each button, and the value is dTv hot <dTv a little hot <0 <dTv a little cold <d
Tv is set to be cold.

A method of calculating the indoor set temperature in the indoor set temperature calculating means 3 in the case where the occupant inputs the sensation from the sensation input means 2 in the above configuration will be described. Using the indoor temperature measurement value Tr measured by the indoor temperature sensor 1 and the sensible value dTv input by the sensation input unit 2, the indoor set temperature TS is calculated using the following equation.

TS = Tr + dTv The TS calculated in this way is determined as the indoor set temperature and transmitted to the air conditioner 4.

As described above, according to the temperature setting device for an air conditioner of the present invention, the occupant can determine an appropriate indoor set temperature only by inputting the sensation, and prevents overcooling and overheating. be able to.

(Embodiment 2) FIG. 4 shows the structure of a temperature setting device for an air conditioner. The same parts as those of the first embodiment are designated by the same reference numerals and detailed description thereof will be omitted.

The indoor set temperature calculating means 3 sends the indoor set temperature calculated from the indoor temperature measured value measured by the indoor temperature sensor 1 and the sensible value input by the sensible input means 2 to the set temperature determining means 5. The set temperature determination means 5 determines the validity of the received indoor set temperature, recalculates the indoor set temperature, and transmits the calculated indoor set temperature to the air conditioner 4. The air conditioner 4 keeps the indoor temperature at a desired value based on the indoor set temperature transmitted from the set temperature determination means 5.

A method of calculating the indoor set temperature in the set temperature determination means 5 in FIG. Here, it is assumed that the indoor set temperature at that time is TSold and the air conditioner controls the indoor temperature. The indoor set temperature TS sent to the set temperature determining means 5 is calculated by the same method as in the first embodiment, and the set temperature determining means 5 determines the validity of the calculated indoor set temperature TS. First, when the indoor set temperature TS exceeds the indoor set temperature upper limit value TSmax, TS = TSmax, and when it is below the indoor set temperature lower limit value TSmin, TS = TSmin. This prevents overcooling and overheating. Indoor setting temperature upper limit value TSmax, indoor setting temperature lower limit value TS
min is preset by the administrator.

Next, the present indoor temperature control state of the air conditioner is in a transient state, and the calculated indoor set temperature T
When S exceeds the current indoor set temperature TSold, that is, when cooling, the following conditions | Tr-TSold |> ΔT and TS <TSold are satisfied. When the condition | Tr-TSold |> ΔT and TS> TSold are satisfied, TS = TSold. ΔT is a constant for determining whether the indoor temperature control is in a transient state, and has a positive numerical value of about 0.5. The TS calculated by the above method is determined as the indoor set temperature and transmitted to the air conditioner 4.

As described above, according to the temperature setting device for an air conditioner of the present invention, the calculated indoor set temperature is appropriately judged in terms of controllability and energy saving, so that the indoor temperature can be set appropriately. It can be carried out.

(Embodiment 3) FIG. 6 shows the structure of a temperature setting device for an air conditioner. The same parts as those of the first embodiment are designated by the same reference numerals and detailed description thereof will be omitted.

The outlet temperature sensor 6 is attached to the outlet of the air conditioner 4, measures the outlet temperature of the air conditioner 4, and sends the measured value to the outlet temperature set value calculating means 7. The air flow sensation input means 8 is installed indoors,
The resident inputs the sensation of the airflow of the air conditioner 4 and transmits the sensation to the airflow temperature set value calculation means 7. The blow-out temperature set value calculation means 7 calculates a new blow-out temperature set value from the inputted blow-out temperature and air flow feeling value, and sends it to the air conditioner 4. The air conditioner 4 keeps the blowing temperature at a desired value based on the blowing temperature set value transmitted from the blowing temperature set value calculation means 7.

The air flow sensation input means 8 inputs the air flow sensation value dTFv using the same interface as the sensation input means 2.

With the above configuration, a method of calculating the blowout temperature set value in the blowout temperature set value calculating means 7 when the occupant inputs a feeling of airflow in FIG. 7 will be described. If the resident is not satisfied with the current blowing temperature,
The air flow sensation input means 8 is used to input the air flow sensation value dTFv for the blowing air flow. Blowout temperature set value calculation means 7
Is the airflow sensation value dT input by the resident to the airflow sensation input means 8.
Fv and the room temperature T measured by the blow-out temperature sensor 6
Using f as an input, the outlet temperature set value TFS is calculated using the following equation.

TFS = Tf + dTFv TFS calculated in this way is used as the outlet temperature set value and transmitted to the air conditioner 4.

As described above, according to the temperature setting device for the air conditioner of the present invention, the occupant can determine the appropriate blowout temperature set value only by inputting the feeling of airflow.

[0029]

As is apparent from the above embodiments, according to the present invention, the occupant can perform the setting operation of the indoor set temperature without being aware of how many times the indoor set temperature is set. The air conditioner that can calculate the indoor set temperature whatever the indoor temperature control of the air conditioner is because the resident's experience of the indoor temperature is used to set the new indoor set temperature based on the measured indoor temperature. It is possible to provide the control device. Moreover, since a comfort index such as a PMV value is not used, it is possible to provide a temperature setting device for an air conditioner that does not require complicated calculation.

Further, according to the present invention, it is possible to provide a temperature setting device for an air conditioner which can prevent wasteful indoor temperature setting by judging controllability and energy saving of the calculated indoor set temperature.

Further, according to the present invention, since the air flow feeling of the occupant with respect to the blowing temperature is used to set a new blowing temperature set value based on the blowing temperature at that time,
It is possible to provide a temperature setting device for an air conditioner that can calculate a blown air temperature set value regardless of the condition of the blowout temperature control of the air conditioner.
