Abstract

PURPOSE:To eliminate large loss of comfortableness even if a user inputs for an excess temperature feel by inputting a PMV (predicted mean hot or cold feeling report) value after being corrected and a control target value, and so controlling cooling and heating means that the PMV value is stabilized at a control target value. CONSTITUTION:When a user feels discomfort due to his favorite, operating amount change, etc., for a PMV value obtained by PMV value calculating means 1, an optimum temperature feeling input is input by temperature feel input means 8. Temperature feel input memory means 11 stores a temperature feeling input value with relation with a cause such as a room temperature, an atmospheric temperature at that time, and the PMV value obtained by the means 1 is corrected by PMV value correcting means 12 in response to an input of the means 8. Simultaneously, when similar environmental conditions are obtained at the time of next operation, the PMV value is automatically corrected in response to the input stored in the means 11, and the corrected PMV value is so limited by PMV value correction control means 12 as not to exceed it at a predetermined range. Accordingly, even if excess temperature feed input is erroneously input, comfortableness is not largely impaired.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner for automatically controlling an indoor environment so that a occupant can feel comfortable.

[0002]

2. Description of the Related Art A conventional air conditioner is controlled to keep room temperature within a certain temperature range, but it should be designed so as to keep the thermal sensation of a person inhabiting the room comfortable. In order to realize such comfort, a comfort index called PMV has been proposed, and Japanese Patent Application Laid-Open No. 2-242037 discloses that the air conditioner is controlled based on this index. PMV (Predicted Mean Bot)
e) is translated as an average expected thermal sensation report, which is one index for evaluating the comfort of thermal environment, and was proposed by Professor Whanger of the Technical University of Denmark, and in 1984 ISO-
7730 has been internationally standardized.

The PMV is a function of environmental factors such as temperature, humidity, radiation temperature and air velocity, and human factors such as the amount of activity and the amount of clothing. From these values, the ISO-7 can be obtained.
It can be obtained by the formula described in 730. The PMV value of 0 is neutral and comfortable, 3 is hot, 2 is warm, 1 is slightly warm, -3 is cold, and -2.
Is defined as cool and -1 as slightly cool. Also, −
90% of people are comfortable in the range of 0.5 <PMV value <0.5, and this range is defined as the comfortable range. The description of the formula and the calculation method will be omitted.

Japanese Unexamined Patent Publication No. 2-242037 discloses that a detection means for detecting temperature, humidity and radiation temperature is installed in a living area,
PM from setting means for setting air flow velocity, activity amount and clothing amount
The V value is calculated, various air conditioners are cooperatively controlled so that the PMV value becomes neutral, and the control target value set in the comfortable range is corrected by the temperature sensation input of "hot" and "cold". .

[0005]

However, in the conventional method, although the control target value is corrected by the temperature sensation input, the optimum temperature sensation input depending on the degree to which the user feels hot or cold cannot be performed, or the excessive temperature sensation cannot be obtained. Comfort is impaired by various warm feeling inputs, and there is the inconvenience that frequent warm feeling input operations are required each time the vehicle is driven. It had a defect such as.

The present invention solves the above-mentioned problems of the prior art, and enables optimum temperature sensation input according to the degree to which the user feels hot or cold, and comfort even if excessive temperature sensation is input. It is an object of the present invention to provide an air conditioner that does not significantly impair the performance of the air conditioner and that eliminates the inconvenience caused by the complexity of repeating the same operation every time the vehicle is driven.

[0007]

In order to achieve this object, an air conditioner of the present invention comprises a cooling / heating means for cooling or heating an interior of a room, and a PMV value calculation means for sequentially calculating a PMV value of a living area. When the user feels it is hot or cold, the temperature sensation input means can input cool or warm in multiple stages according to the degree, and the cool side and warm side have multiple stages respectively and one-stage display in the center The temperature sensation input display means configured to display the temperature sensation input means in response to the input of the temperature sensation input means, and to leave the display of the input at the center to leave the display of one step at a certain time, and the temperature sensation input at room temperature at that time. Temperature input storage means for storing in association with factors such as temperature and outside temperature, and the P input according to the input of the temperature input means and the temperature input stored by the temperature input storage means.
PM for correcting the PMV value obtained by the MV value calculation means
V value correcting means, PMV value correction limiting means for limiting the corrected PMV value so as not to exceed a predetermined range, control target value specifying means for specifying a control target value within the comfortable range of PMV, and after correction A cooling / heating control means for inputting the PMV value and the control target value and controlling the cooling / heating means so that the PMV value becomes stable at the control target value is provided.

Further, in the air conditioner of the present invention, the temperature sensation input in the transition period is determined by the transition period determination means for determining whether the PMV value is in the transition period toward the control target value and the input from the transition period determination means. The temperature sensation input storage means which does not memorize is provided.

[0009]

According to the present invention, with the above-described structure, it is possible to input the optimum temperature sensation according to the degree to which the user feels hot or cold, and even if the excessive temperature sensation is input, the PMV value falls within the predetermined range. Since the correction value is limited so as not to exceed, comfort will not be greatly impaired.

Further, since the temperature sensation input is stored in association with factors such as the room temperature and the outside temperature at that time and carried over at the next driving, it is not necessary to repeat the same temperature sensation input operation every time the vehicle is driven. .

In addition, since the temperature sensation input that is input during the transition period of the PMV value toward the control target value is not stored as a special case, it is possible to store unnecessary input and not to impair comfort. .

Since the system is provided with the cooling / heating control means 16 for controlling the cooling / heating means 14 so that the value becomes stable at the control target value, it is possible to input the optimum temperature sensation according to the degree to which the user feels hot or cold. Moreover, since the correction value is limited so that the PMV value does not exceed the predetermined range even if an excessive temperature sensation is input, comfort is not significantly impaired.

Further, since the temperature sensation input is stored in association with the factors such as the room temperature and the outside temperature at that time and carried over to the next operation, it is not necessary to repeat the same temperature sensation input operation every time the vehicle is operated. .

A second embodiment of the present invention will be described below with reference to the drawings. FIG. 3 is a block diagram of the air conditioner of this embodiment. Detailed description of the same parts as those in the first embodiment shown in FIG. 1 will be omitted. Reference numeral 26 is a transition period determining means for determining whether or not the PMV value is in a transition period toward the control target value based on signals from the PMV value correcting means 12 and the control target value designating means 15. The temperature sensation input during the transition period is not stored by the input from the transition period determination means 26.

The operation of the air conditioner having the above configuration will be described. In FIG. 3, the transition period determining means 26 determines whether or not the PMV value is in the transition period toward the control target value, that is, within ± 0.5 (a range where 90% of people feel comfortable). When the temperature sensation is input during the transition period, the work load of the user temporarily changes, and if this temperature sensation input is stored and the PMV value is automatically corrected during the next operation, the work load differs from the previous day. This in turn results in a loss of comfort. Therefore, when it is determined to be in the transition period, the warm sensation input storage unit 11 'does not store the warm sensation input. Since it is memorized and learned only when it is not in the transitional period, the steady temperature sensation input is stored and the sudden temperature sensation input is not stored.

As described above, the air conditioner of this embodiment is the first
The air conditioner of the embodiment is provided with a transition period determination means 26 for determining whether the PMV value is in the transition period toward the control target value, and the temperature sensation input storage means 11 ′ is input by the transition period determination means 26. Since the temperature sensation input during the transition period is not stored, the temperature sensation input during the transition period when the PMV value is toward the control target value is not stored as a special case, so unnecessary inputs are stored instead. It doesn't hurt your comfort.
