Abstract

PURPOSE:To make it possible to select an operational mode adapted to the body feeling of a user by operating switching means when the user felt that the condition of indoor air is comfortable to store the temperature and humidity at that point in time, and determining the zone sorting threshold value in the case of next operation on the basis of these stored values. CONSTITUTION:When the user manipulates switching means 3 when he felt most comfortable during the operation, the detected value TM of a temperature sensor 1 and the detected value HM of a humidity sensor 2 are stored in memory means 4. Next, when the operation is stopped and again started, zone setting means 5 determines the zone sorting threshold value in the case of next operation on the basis of detected values TM and HM stored in memory means 4, and selects the operational mode in accordance with the operation starting temperature and the zone to which the operational mode is selected, so that the operational mode matching for the body feeling of the user can be selected.

Description

Detailed Description of the Invention [Technical Field of the Invention] The present invention divides at least the temperature fluctuation range of the temperature and humidity in a room where air conditioning is performed into a plurality of zones, and adjusts the temperature at the start of operation, or The present invention relates to a control method for an air conditioner that selects an operation mode according to the zone in which temperature and humidity belong.

[Technical background of the invention and its problems]

To keep the indoor air in a comfortable condition, the amount of heat that must be provided per unit time by air conditioning is called the heating load, the amount of heat that must be removed is called the cooling load, and the amount of cooking required for humidification or dehumidification is called the air conditioning load. . This air conditioning system can be roughly determined by detecting the indoor temperature and humidity.

On the other hand, the air conditioner detects temperature and humidity, and selects an operation mode such as cooling, heating, dehumidification, or ventilation depending on the air conditioning load at the start of operation. Operation continues in the selected mode. This will be explained using FIG. 3.

First, there are four temperatures T1 that serve as standards for the indoor temperature fluctuation range.
．． T2. T3 and T4 (T1>T2>
T3>T4), while setting 21ii! Relative humidity (hereinafter simply referred to as humidity) is 75%, which is the standard for the fluctuation range of Maro.
].

Next, use these set values as thresholds and set the temperature and humidity range to 8, 8. Divided into four zones, C and D. That is, zone A is higher than temperature T1, zone B is a combination of a range that is lower than temperature T1 and higher than temperature T2, and a range that is lower than temperature T2 and higher than temperature T3, and the humidity exceeds 75 [%], and zone B is higher than temperature T2. C zone, temperature T4J, which includes a range that is low and higher than temperature T3 and has a humidity of 75% or less, and a range that is lower than temperature T3 and higher than temperature T4:
It appears in the low D zone.

In addition, in the operation of the air conditioner, the control target temperature T, which is left to the user's selection, is the temperature T2 or the temperature T2 mentioned above.
3 or close to it.

According to these zone classifications, for example, if the detected values of temperature and humidity at the start of operation belong to the Δ zone, the control target is the set temperature TS, and if the cooling operation targets the set temperature T, if it belongs to the B zone, the set temperature T, Dehumidification operation is performed with the control target and η. Further, if the detected values of temperature and humidity at the start of operation indicate that the vehicle belongs to the C zone, a ventilation operation is performed in which only blowing lice is performed, and if the vehicle belongs to the D zone, a heating operation is performed.

In addition, in this operation mode selection, ventilation operation is selected at the start of operation, and after that, when moving to zone B or zone D, the operation shifts to dehumidification operation or heating operation, respectively, but if an operation mode other than this is selected at the start of operation. In this case, the vehicle will continue to be operated in the same mode.

Here, the temperature and humidity that serve as the basis for zoning are determined based on the average person's experience, and since these values are fixed, the problem is that it is not possible to select a driving mode that suits the individual's experience. was there.

[Purpose of the invention]

The present invention has been made to solve the above-mentioned problems, and aims to provide a control method for an air conditioner that allows a user to select an operating mode that suits his/her personal experience.

[Summary of the invention]

In order to achieve this object, the present invention provides a switch means that can be operated at a desired time, and a storage means that stores detected values of indoor temperature or temperature and humidity in response to the operation of this switch means. In preparation, when the user feels that the indoor air condition is comfortable, the user operates the switch means to store the current temperature or temperature and humidity in the storage means, and uses the stored value as the basis for the next operation. This determines the threshold for zoning when

[Embodiments of the invention]

FIG. 1 is a block diagram showing an example of the configuration of a device for implementing the present invention, which includes a temperature sensor 1 and a humidity sensor 2 that detect indoor temperature and humidity, respectively, and a humidity sensor 2 that is operated at a desired time. T! When the switch means 3 such as a push button switch is operated, the storage means 4 stores the detected value TH of the temperature sensor 1 and the detected value HH of the humidity sensor 2, respectively. and zone setting means 5 for setting a zone for selecting an operation mode based on the stored value of No. 4.

° The operation of the air conditioner configured as described above will be explained below with reference to FIG. 2 as well.

First, temperature and humidity values that are considered optimal for installation are stored in a storage means (not shown), and based on these stored values, the zone setting means 5 sets the zone similar to that shown in FIG. 3, for example. Let's do it. The control target temperature at this time is “SH”
Then, the detected values of temperature and humidity at the start of operation are A~
The operation mode is determined depending on which zone in the back of D it belongs to, and from then on, operation is continued in substantially the same mode with the target temperature TS)l.

During this operation, when the switch means 3 is operated when the user feels most comfortable, the detected value TH of the temperature
, the detected value H of the humidity sensor 2, and udon are stored in the storage means 4. These detected values THJ'5 and HH are stored as they are even after the operation is stopped.

Next, when the operation is stopped and restarted, the zone setting means 5 sets the J: Una zone shown in FIG. That is, the detected temperature value TH stored in the storage means 4
TH-2,4C lower by 2 (“C) than this based on
TH-4, which is lower by 5 (℃), and TH-5, which is lower by 5 (℃), are calculated, and the detected humidity value H stored in the storage means 4 is calculated.
Calculate t-+, +1S which is 15 [%] larger than H. These are the temperatures T, , T2 . T3. Corresponds to T4 and humidity 75 [%].

Subsequently, the zone setting means 5 sets these detected values TH and calculated values TH-2, TH-4, T, -s, 1l-
Zoning is performed as shown in FIG. 2 using IH+15 as a threshold value.

Then, the operation mode is determined depending on which zone from △ to D the temperature and humidity at the start of operation belong to, and from then on,
Driving can be continued in almost the same mode with the target of 4 degrees and 3M.

Thus, when the user feels that the indoor air condition is comfortable, the user operates the switch means 3 to set the zone and select the driving mode according to the user's experience.

Although the above embodiment describes an air conditioner that detects both indoor temperature and humidity and selects an operation mode, the present invention divides only the range of temperature fluctuation into multiple zones regardless of humidity fluctuation. The present invention can also be applied to an air conditioner that selects an operation mode depending on the zone to which the temperature at the start of operation belongs.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, the temperature or temperature and humidity at which each individual user feels comfortable is memorized, and based on this memorized value, zone division is performed when driving next time. The operating mode is selected according to the temperature at which operation starts, or the zone to which the detected temperature and humidity values belong, so that the operating mode that matches the experience of each individual user is selected. effective.
