Abstract

PURPOSE:To realize efficient optimum operation by a method wherein the load characteristics of the day is estimated from the load characteristics measured over the past few days in order to obtain necessary hours for precooling or preheating operation. CONSTITUTION:Signals from a temperature sensitive unit 1 equipped with a active element 3 issuing the output in proportion to room temperature by means of a temperature sensitive element 2 and resistors are converted at an A/D converter 4 into digital signals and inputted to a calculating unit 6 in order to be stored in a memory element 7, to which starting times for use of air-conditioned rooms, set room temperatures, operating temperature rises on the first day and the like are also inputted from a key switch group 5. Necessary preheating hours t=aXDELTAtheta, which is corresponding to the difference DELTAtheta between room temperature and the set room temperature, are determined as loading characteristics on the previous day based upon the stored values just mentioned above. When the difference DELTAtheta between the room temperature of the day and the set room temperature is obtained, the necessary preheating hours (t) are calculated at the calculating unit 6 based upon the loading characteristics of the previous day in order to control an outdoor fan 9, an indoor fan 10, a compressor 11 and a four- way valve 12. Furthermore, an oscillator unit 8 controls the calculating unit 6 on time.

Description

DETAILED DESCRIPTION OF THE INVENTION When the present invention starts using an air conditioning room, the precooling and preheating operations are redistributed in a separate I:9 air conditioner that performs precooling and preheating operations to reach a predetermined set temperature. Optimal time C: This is to prevent wasteful operation and incomplete air conditioning by selecting the optimum time.

Conventional, pre-cooling and pre-heating operation! The method for determining the start time is to use a timer to set the start time of precooling or heating operation, or the administrator of the air conditioner arbitrarily determines the start time of precooling or preheating operation, but the former. In the case of 9rJ, the optimum time to start operation is determined.In other words, if the start time is early≦2, the set temperature value is reached before the air conditioning room starts to be used, resulting in unnecessary operationC.
Two. Moreover, the larger the air-wafer type equipment, the greater the waste of energy consumption. In addition, if the operation start time is late, even when the air conditioning room starts using the set temperature range, it may not reach the set temperature range and feel uncomfortable. Precooling and preheating operation start times can be set arbitrarily based on room temperature changes, etc.
Decisions were made based on the predictions and judgments made by one person.

Control of the air conditioner of the present invention] The device precools the air conditioning room Y to reach a separately determined set temperature C;

In an air conditioner that performs preheating operation, the temperature sensing element that senses the room temperature of the air conditioning room and the temperature change characteristics of the temperature sensing element during precooling and preheating operation are measured as the load characteristics of the air conditioning room from the previous day to the past several days. , a calculation unit that calculates the precooling and preheating operation start time of the day from the stored value of the storage unit, and an oscillator unit that sequentially outputs calculation signals to the calculation unit, and from the calculation unit Since the precooling and thermal operation is started by comparing the predicted precooling and preheating operation start time with the current time, the above-mentioned problems are solved and the optimal precooling and preheating operation start time is determined to provide efficient and comfortable air. -It is something that performs sum.

An embodiment of the present invention will be described below based on the diagram (2).

Below, the operation of the control at 1M direct of the air conditioner according to the present invention will be explained for the case of preheating operation during heating operation. Set room temperature at the start of operation (θ
BET), initial operating temperature rise value (an), etc. are input using the t-dice 11 group (5) and stored in the memory element (7).

Based on this memorized value, the room temperature value (#
) and the required preheating time of the air-conditioning room for the temperature (θam and !l(Δ-)). memorize to.

t-1×Δθ ・(11 In Figure 6, when Δθ is determined, the required preheating time (tl
is determined, and the preheating start time is determined in accordance with the start time of use.

This series of operations to determine the preheating start time is performed one after another at regular intervals (for example, 1 minute) from a predetermined time (for example, 4 hours) before the start time of the air conditioning room, and the preheating start time and The preheating operation is started from the time when the two times match or the current time has overtaken the preheating start time Mtl. After this, the operating temperature increase value (K1)', which is determined from the increase in the silkworm temperature measured by the preheating operation feeling 2!
'The preheating start time after the 28th cycle is automatically determined in the same way as above by extracting the load characteristics after the 28th cycle as a reference.

In other words, the first day's operation will be explained based on the load characteristics shown in Fig. 6 and the measured room temperature values shown in Fig. 4. If the air conditioning room's use start time (Topmst) is '4t9 o'clock, then the generator section (
8; outputs a signal at regular intervals from time (To) (5 o'clock) to control the operation section (6). From this signal 6: the calculation unit (6) calculates the room temperature from the temperature sensing element (211 = temperature sensing unit 11).
1. The set room temperature (#3) is input via A/D conversion (4).
Difference from recommendation (j#1) Y, roughness (: Required preheating time (

Determine preheating start time (T2) v1! Enter. Similarly, preheating start time (T5), (T4) is determined every time (Δt) passes. At the same time, preheating is started from calculation section +6)C. Compare the time with the current time and find out whether the preheating start time and the current time match or the current time has overtaken the preheating start time (T
At 4), operation signals for the outdoor fan (9), indoor fan θG compressor 1υ are output from the calculation unit (6), and preheating operation is started.

After this, the time required for the room temperature to rise during the preheating operation and reach the set room temperature is calculated by the calculation unit (61 (= actual measurement on the first day))
: Calculate the operating room temperature rise value (lL117) and calculate the average value of the operating room temperature rise value (K0) obtained on the previous day by calculating the 26th operating room temperature rise value tlLl'2. ).

The $2nd IC; determines the preheating start time from the operation 42 of the calculation unit (6) similar to the first day based on the operating temperature rise value (town) stored in the storage unit (71), and starts the preheating operation. Similarly, the 28th actually measured operating temperature increase value (12)V is calculated and the load characteristic is stored in the storage section (7).
