DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thermal environment control device for controlling an air conditioner by detecting a thermal sensation of a human body in an air-conditioned space.

[0002]

2. Description of the Related Art Conventionally, a thermal environment control apparatus 1 of this type comprises a thermal detection section 2 comprising a thermal detection element 3 and a control section 4, and a signal generation section 9, as shown in FIG. The heat detecting element 3 is formed by an outer shell 11 which is determined by heat generated by a heating element 12 which is an electric resistor provided inside the outer shell 11 and a heat balance between the ambient temperature, airflow and radiant heat through the outer shell 11. The control unit 4 includes a temperature detector 13 such as a thermistor that detects an internal temperature, and the controller 4 performs power transmission corresponding to the amount of heat released by a human body through a power supply line 14 connected to the heat generator 12 and transmits the power to the temperature detector 13. In this configuration, the temperature of the thermal detection element 3 is detected through the connected signal line 15 and an output equivalent to the thermal sensation of the human body is generated. The signal generator 9 generates a signal for controlling the air conditioner 10 based on a difference between an output of the controller 4 and a predetermined set value.

[0003]

However, in the above-described configuration, when the thermal sensation rapidly rises from an environmental state in which the thermal sensation is out of an allowable value, such as when the air conditioner is started to operate, the thermal detection unit is not used. Although the output has a time delay in response, the output also changes according to changes in environmental conditions, whereas the human body has a delay in physiological responses such as acclimation, so the thermal output which is the output of the thermal detection unit There is a difference between the amount of sensation and the amount of sensation actually felt by the human body. In particular, there has been a problem that when the amount of change in the environmental state is large, the change becomes large.

The present invention has been made to solve such a conventional problem, and takes into account a delay in physiological responses such as acclimation of the human body when the human body rapidly rises from an environmental state in which the thermal sensation is out of an allowable value. An object is to obtain, as an output, a thermal sensation amount that matches the sensation amount felt by the human body.

[0005]

In order to solve the above-mentioned problems, a thermal environment control device according to the present invention comprises: a determination unit for determining whether a signal from a thermal detection unit is within an allowable value or outside; A storage unit that stores the signal, a calculation unit that calculates the amount of change of the signal of the thermal detection unit from the value of the storage unit when the signal of the determination unit is out of the allowable value, A correction unit that corrects and outputs a value and a signal generation unit that generates a signal for controlling the air conditioner from outputs from the thermal detection unit and the correction unit are provided.

[0006]

According to the present invention, when the determination section determines that the signal from the thermal detection section is outside the allowable value, the calculation section calculates the amount of change in the signal of the thermal detection section from the value of the recording section. Since the correction unit corrects and outputs the value of the thermal detection unit according to the value, even if the environmental condition changes rapidly, the human body takes into account the delay of the physiological response such as acclimation of the human body. The amount of thermal sensation that matches the amount of sensation felt by the user can be obtained as an output.

[0007]

An embodiment of the present invention will be described below with reference to FIG.

In FIG. 1, a thermal environment controller 1 detects a thermal environment state of an air-conditioned space and outputs a thermal sensation amount of a human body, and a signal from the thermal detector 2 is allowed. A judgment unit 6 for judging whether or not the value is within a value; a storage unit 5 for storing a signal of the heat detection unit 2; A calculation unit 7 for calculating the amount of change in the signal; a correction unit 8 for correcting and outputting the value of the heat detection unit 2 in accordance with the value of the calculation unit 7; Harmonic machine 10
And a signal generator 9 for generating a signal for controlling The heat detecting section 2 is the same as the conventional example, and includes a heat detecting element 3 and a control section 4.

In the above configuration, the thermal detector 2 installed in the air-conditioned space uses the power supply line 14 from the controller 4.
The temperature inside the outer shell 11 determined by the amount of heat generated by the electric power corresponding to the amount of heat released from the human body supplied to the heating element 12 through the outer shell 11 and the heat balance of the ambient temperature, airflow and radiant heat through the outer shell 11 is detected. It is detected by the body 13 and sent to the control section 4 through a signal line 15 connected to the temperature detecting body 13 to generate an output equivalent to the thermal sensation of the human body.

When the judgment unit 6 judges that the output from the heat detection unit 2 is within a predetermined allowable value, the output from the heat detection unit 2 is sent to the signal generation unit 9 as it is, and when the output deviates from the allowable value, The arithmetic unit 7 calculates the amount of change in the signal from the value of the thermal detection unit 2 stored in the storage unit 5, and the correction unit 8 corrects the value of the thermal detection unit 2 according to the value to generate a signal. Is output to In the signal generator 9,
A signal for controlling the air conditioner 10 is generated based on a difference between the obtained signal and a predetermined set value.

As described above, according to the thermal environment control apparatus 1 of the embodiment of the present invention, the determination section 6 determines whether or not the output from the thermal detection section 2 is within a predetermined value. If the value deviates, the arithmetic unit 7 calculates the amount of change in the signal from the value of the thermal detection unit 2 stored in the storage unit 5, and the correction unit 8 corrects the value of the thermal detection unit 2 according to the value. Thus, even when the environmental condition changes rapidly, the amount of thermal sensation that matches the amount of sensation felt by the human body is obtained as an output even in the case where the environmental condition changes rapidly, taking into account the delay in physiological responses such as acclimation of the human body. The effect is that you can do things.

[0012]

As described above, in the thermal environment control apparatus of the present invention, it is determined whether or not the output from the thermal detector is within a predetermined value. The amount of change in the signal is calculated from the value of the heat detection unit, and the value of the heat detection unit is corrected according to that value and output to the signal generation unit. In addition, there is an effect that a thermal sensation amount corresponding to the sensation amount felt by the human body can be obtained as an output, taking into account the delay of physiological responses such as acclimation of the human body.
