Abstract

PURPOSE:To determine the advance time and modulate the set room temperature so as to improve the comfortableness and energy consumption by providing a means to count the elapse of the advance time, a means to modulate the set room temperature in relation to the time period up to the set time and a means to regulate the upper limit of the advance time. CONSTITUTION:A correction graph information holding section 4 holds the information regarding the correction graph. A temperature difference information computing section 3 outputs the temperature difference information DELTAt based on the room temperature Tr and the outside air temperature Toa. An advance time determining section 5 determines the advance time and directs the advance operation based on the temperature difference information DELTAt and the information in the correction graph information holding section 4. For heating operation, the set room temperature TRS is first controlled at a level which is lower than the desired room temperature TR by DELTAT7, and is brought near to the desired room temperature TR as the set time ts approaches.

[Problem that the invention seeks to solve]

With conventional air conditioner front-load operation control devices, the set front-load operation time is calculated to be longer than necessary, which not only goes against energy conservation, but also sets a target indoor temperature, which may cause the room to become too warm during heating, especially during sleep. There were also problems from a health and comfort perspective, as the air conditioner would cool down too much.

This invention was made in order to solve these problems.It uses a learning function to limit the upper limit that determines the advance time, and also changes the indoor temperature setting as the advance time elapses, improving comfort and energy saving. The purpose of this invention is to obtain an air conditioner advance operation control device that aims to improve performance.

[Means for solving problems]

The air conditioner front-loading operation control device according to the present invention includes means for measuring the progress of the front-loading time, means for changing the indoor temperature setting according to the time until the set time, and means for specifying an upper limit value for the front-loading time. It has been established.

[Effect]

In this invention, by changing the indoor temperature setting according to the remaining time until the set time, the indoor temperature gradually approaches the indoor target temperature.

〔Example〕

Embodiments of the air conditioner advance operation control device of the present invention will be described below with reference to the drawings. FIG. 1 shows the configuration of an embodiment of the present invention, in which 1-i (i=0.1
...) are a plurality of air conditioners, and 2-i and 2a-i are temperature sensors that detect outside air temperature, indoor temperature, indoor air outlet temperature, etc.

The temperature difference information calculating section 3 and the correction graph information holding section 4 are configured to output to the advance time determining section 5.

On the other hand, 6 is a rise time correction processing section, and the correction graph corrected therein is stored in the corrected correction graph information holding section 7.

The remaining time timer 8 counts the remaining time until the set time, and the indoor temperature setting unit 9 changes the indoor temperature setting based on this remaining time.

FIG. 2 is an example showing how to change the indoor temperature setting TR3 according to the present invention. Further, FIG. 3 is a flowchart showing a processing procedure for carrying out an embodiment of the present invention.

Next, the operation of the present invention will be explained with reference to FIGS. 2 and 3.

The correction graph information holding unit 4 stores information regarding correction graphs, such as the bold line shown in FIG. 6, for example.

In FIG. 6, the horizontal axis represents temperature difference information (described later) Δt according to the present invention, and the vertical axis represents the advance operating time H. The right side from the center in FIG. 6 corresponds to heating control, for example, and the left side from the center corresponds to cooling control. For example, when the temperature difference information Δt is the value X2, the advance operation time H is selected to be the value Y+ and the value Yl
(minutes) earlier to start driving.

The temperature difference information calculation unit 3 shown in FIG. 1 performs step 10.1.
1, for example, based on the indoor target temperatures T, I, the indoor temperature T, and the outside air temperature rom, the temperature difference information Δt is Δ'''' 1 (TI-Tr) + (TF-TOI)
Xβ1...The result of the calculation (1) is output.

However, in Equation (11), β represents a coefficient.

Next, in step 12.13, the advance time determining unit 5 determines, based on the obtained temperature difference information Δt and the contents of the correction graph information holding unit 4, that if the information Δt is, for example, X2, A value Y is determined as the advance operation time H, and a predetermined air conditioner 1-i is instructed to operate in advance.

Next, in step 14.15, the set time T
When the remaining time until s reaches Δte4 and the heating operation is in progress, the indoor set temperature TR3 is controlled at a value ΔT lower than the indoor target temperature Ti (temperature desired by the customer when the set time is reached), and the remaining time Δt, 3. It decreases as Δt, t, Δti+, and as the set time t3 approaches, the indoor set temperature TR3 becomes TI−.
ΔT4,T,l-ΔT3,T,-ΔT4(ΔT,>ΔT
&>ΔT, >ΔT,), the temperature approaches the indoor target temperature TR.

When the remaining time reaches Δt3°, the indoor set temperature TI is controlled using the indoor target temperature T, l.

However, in reality, an error occurs between the result of indexing the correction graph information and the time it takes to actually reach the desired indoor target temperature.

Therefore, in step 15.16, the rise time correction processing unit 6 shown in FIG.
Assuming that the indoor target temperature has been reached, the correction graph information shown in FIG. ′) , (
Rewrite the graph to a graph that passes through X3 Yt ) (step 17). The results are stored in the corrected corrected graph information holding unit 7.

The contents of this holding section 7 are used as the contents of the correction graph information holding section 4 shown in FIG. 1, for example, in the next control.

FIG. 4 is a flowchart showing the operating procedure of another embodiment of the invention. In this FIG. 4, in step 12, Δ
After determining the advance time H based on t and the correction graph, in step 17-a, the advance time H is set to the upper limit of the advance time
If it is smaller, that is, H≦X, proceed to step 13, and if H≦X, proceed to step 17-b, where H=X.
shall be.

The rest shows the same operating procedure as the flowchart in FIG.

The flowchart in FIG. 4 allows the advance time determining unit 5 to
As in steps 17-a and 17-b, the upper limit value X of the advance time is set, and even if the load on the air conditioner is large and the indoor target temperature cannot be reached, the advance time can be prevented from becoming longer. This makes it possible to reduce unnecessary operation and save energy.

Further, in order to obtain a similar effect, an upper limit value of the correction graph may be set in the rise time correction processing unit 6 that corrects the correction graph.

Furthermore, the same effect can be obtained even if the indoor target temperature TI is changed based on the temperature difference information Δt so that the indoor temperature T reaches the room temperature target temperature T8.

〔Effect of the invention〕

As explained above, in this invention, the remaining time Δt.

By changing the indoor temperature setting 'r'ms,
Since the indoor temperature T before reaching the set time t is suppressed, wasteful operation is reduced, energy saving is achieved, and health and comfort are improved.

Furthermore, by setting an upper limit on the advance time, it is possible to maintain the comfort of the user when the indoor temperature T, cannot reach the indoor target temperature T, reduce unnecessary operation, and obtain the same effects as above. .
