[Conventional technology]

For example, the conventional device scans the temperature 7J [No.
Further, past data is modified 1'i[, a predicted tune is calculated by a computer, and the precooling/preheating time is determined based on this predicted curve.

[Problem to be solved by the invention]

The above-mentioned conventional RI technique had problems because it did not take into consideration the following points.

(1) Temperature acclimatization elements installed in each air conditioned space are usually installed inside the indoor unit body of an air conditioner and/or installed inside a controller for remote worship. There is something. Therefore, a predicted curved edge is created using representative temperatures of at most two points. However, there are many different forms of air-conditioned spaces. 1! The temperature distribution across the air can vary greatly depending on its form and the position at the base of the air conditioner. Therefore, with conventional technology that does not take this point into consideration, even if a certain part of the air-conditioned air system reaches the appropriate temperature at a predetermined time after the end of the pre-cooling and pre-heating time, other parts may not reach the appropriate temperature. The problem is that things can happen.

(2) In the conventional technology, the predicted ms is corrected using past data, but there is no past data at the time of installation. Therefore, it has a semi-standard form. The pre-cooling pre-S time is set according to the size of the large air space. Therefore, the form of mouth air A4 air view. Depending on the size, 1 @ is not necessarily at the specified time at the beginning! ! There was a problem that I didn't have enough time.

The purpose of the present invention is to provide g! From the beginning of the establishment of the air-conditioned space, the size, shape, and construction of the air-conditioned space were determined. To provide an air conditioner capable of keeping a living space at an appropriate temperature regardless of the installation position of the air conditioner.

[Means for solving the problem] In order to achieve the above purpose, non-invention is required.511'! j

an input means for inputting information at the time of installation of the Japanese machine; a means for semi-permanently storing the installation environment information; and a means for storing the installation environment information semi-permanently in the non-volatile storage means; 1tlJ# means was added to the air conditioner to control the air-conditioned space using an algorithm based on the 4-environment information and other operating control information such as temperature extracted from the temperature control 4IX.

[Effect]

Due to the environmental compensation recorded in the non-emission storage means, the control means performs the following control according to a predetermined algorithm, making it possible to maintain the entire living space at an appropriate temperature from the time of installation. It becomes dryable.

(1) Depending on the size and form of the IN air-conditioned space and the installation position of the air conditioner, the air may be directed towards the center of the air-conditioned space, or the wind direction angle may be changed up, down, or to the left, and the entire living space may be temperature distribution can be made more uniform.

Also, air coverage w4g! In between, g due to gentleness! Due to the difference in the air ratio of 1, there will be a temperature difference between the top and bottom, but depending on the installation environment information, the temperature thrown into the air conditioner itself! [Since the height of the detection element above the floor is known, it is possible to correct the temperature difference between the upper and lower sides of the living space and to keep the living space at an appropriate temperature.

(23 11g! Since the heat load can be calculated from the installation environment information such as the size of the controlled space and the thickness of the wall, it is possible to set an accurate pre-cooling and pre-heating time from the beginning of installation.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 8.

FIG. 1 is a block diagram expressing the present invention by means of functional implementation means. The input hand Rl is composed of an input unit IA and an input circuit section IB. Rather than input means,
The installation environment information and driving control algorithm suitable for the installation environment are input. As for the driving control algorithm, various types of algorithms may be built into the Air Shinwashin's fugitive memory hand R2, but normally,
Since the calculation + stage 3A and non-volatile storage means 2 built into the air conditioner are a microcomputer and P-ROM, it is difficult to store the algorithms that are not used in the environment. Since there are major disadvantages in terms of both cost and cost, we have decided to include information on the installation environment and the number of people involved. FIG. 7 shows details of an example of an input unit. Form of air-conditioned space! 2! Tablet digitizer for inputting the installation position of the air conditioner

The thickness of the wall between.・Enter the information on the quality of the equipment and the area where it will be installed using the keyboard of the personal computer. Specific heat of each A1 capsule material. heat transfer i
Physical property data such as l ratio. Meteorological data for each region where it is installed is stored in the floppy disk lAc, and based on this information, the personal computer 1λa is able to measure the temperature of the air-conditioned space. Calculate the heating load, combine this with information on the shape of the air-conditioned space and the installation location of the air conditioner, and select the most compatible algorithm from the algorithms for each tank stored on the floppy disk IAc. Write in sexual memory 10th step 2.

The input unit IA may be used as part of the air conditioner, but it must be used only once during installation, and the price is low. Since there is a disadvantage in terms of space, removable connection terminals IAe and IBb are provided between the input circuit IBa and the input circuit IBa so that they can be removed from the air conditioner. As a result, the human unit only needs to be kept by Tosha, which installs the air conditioner.

Therefore, the addition of this function does not increase the economic burden of each of the 4Is of the air conditioner.

Figures 2 to 6. According to Figure 8, the installation environment standard JC
The driving control algorithm based on this will be explained. Figure 2 is. Air-conditioned space with a rectangular plane j
This shows an example of wind and wind control based on different installation positions. Person, B, and C are each air! 4 Shows the paving position of Waiso. In part A, the air blows out toward the front of the air conditioner, and in part B, the air blows out while the wind direction angle is constantly changing from side to side. In cs, when looking at the air i4 Qishin, the left side is the same, and the T that comes out next is the same as the center of the air space.

Figure 1X3 shows a column installed in a mechanical fitting with a non-rectangular plane. In this case as well, as with B in Fig. 42, it is suitable to constantly change the direction and angle of the wind from side to side and blow out the air at 71, but depending on the blowing direction, the direction of the air in the air-conditioned space may vary. # Since the amount is different, the speed of change in the wind direction is not constant, and if the blowing time for each arrow direction is t1a"le"@T, then 1
,＞． 1, ) It is suitable to control the power so that it becomes 1K.

FIG. 4 shows control based on differences in the installation height of the air conditioner from the floor surface. Generally, in a heavily air-conditioned space, it is inevitable that the air will have an i-5 degree distribution in the upward and downward directions due to the difference in air pressure.

g! When the air conditioning* has the internal elements of air conditioning, the temperature of the living space within the space covered by air, lft. In order to maintain a moderate temperature, it is necessary to correct the temperature difference caused by the height of the air conditioner above the floor. D and B indicate the installation position of the air conditioner, respectively, and the height from the floor is indicated by doves and doves. When the temperature of the living space is 'o' (this t0 differs depending on whether it is used as a Japanese or Western room), the height of the bow is 'Im, and the height of the pigeon is t1.

Therefore, the air conditioners installed in section D or B@ can adjust the living space appropriately by correcting and controlling the temperature of t1-"e m"@t6, respectively. .

Figures 5 and 6 are the average of the air-conditioned space at the start of m room!
This shows the characteristics of plexus and time.

Even if the same air conditioner is operated at the same outside temperature, if the size of the air-conditioned space changes, the IPI ill will come true. Also, even if the size is the same, if the thickness of the pot changes, the time it takes to reach the pot will differ. According to the present invention, I! Based on information such as the so-called space size and wall thickness, the estimated S time can be estimated at approximately 1, 1, 1●, respectively, from the beginning of installation. T? It is possible to do something like this.

FIG. 8 is a refrigeration cycle system diagram of one embodiment of the present invention. This is a multi-room air conditioner, with outdoor unit 13
and a plurality of N-yen units 14. It is composed of 15. Note that a plurality of indoor units can be connected to the refrigerant distributor 16, but these are omitted in this figure. These M
Circle unit 14. 15 has various uses. size. Although it is installed in an air-conditioned space of the same type, at the time of factory construction, they were the same. The maximum power of the air conditioner is determined by the pressure generator 13 built into the outdoor unit 13 and the outdoor heat exchanger 6.

The product specifications of each indoor unit are determined by the iA rotation control algorithm input by one person from the input unit shown in FIG. 7 at the time of installation. For example, a slightly larger cover such as living noreme! If installed in a controlled space, increase the rotation of the indoor air blower 8A to cool the room. The heating capacity is increased. In addition, air space Il4g is used for applications such as washrooms, which are small and used only for a very short time, but need to reach a predetermined temperature in a short time! If the indoor unit is installed between
A control algorithm is included.

In addition, precooling may vary depending on the installation location of the indoor unit and the size of the air-conditioned space. The preheating time is controlled by IN2 diagram to 6th diagram.
This is as explained in the figure.

Regarding pre-cooling and pre-heating times, since the user is usually absent, control is performed that is appropriate for the installation environment, regardless of the wind direction set by the user. This is in accordance with the following.

In addition, in automatic operation mode, the wind direction etc. are pre-cooled. Control is performed in the same way as the preheating time.

Also, if the load does not match during installation, you will know right away.
This also has the effect of eliminating the risk of trouble later on.

〔Effect of the invention〕

According to the present invention, there are the following effects.

(1) Air coverage! Accurate cooling in 4 spaces. By knowing the heating load characteristics, you can accurately pre-cool from the beginning of installation. Pre-M driving is possible.

<2) '4 Thickness of air-conditioned space. Depending on the configuration, wind direction control and the installation height of the air conditioner. It becomes possible to correct the difference in the lower temperature It, and it is possible to make the @sho space an appropriate temperature.

(3) Since the control method of the air conditioner can be inputted according to the purpose and size at the time of installation, it is possible to standardize factory production and reduce distribution inventory by 6U.
