Abstract

PURPOSE:To prevent an abnormal increase of a room temperature from occurring when room temperature setting is made erroneously, by a method wherein the upper limit of producible capacity of a compressor is controlled by providing a controller controlling a speed of the compressor variably when a room temperature is continued for more than a fixed period of time under a state wherein the room temperature is more than a fixed level. CONSTITUTION:During the operation of an air conditioner in the lapse of a fixed period of time tc after a temperature of an indoor unit 7 exceeded a fixed level, a signal through which a speed of a compressor 4 is made into n1 is signaled to an inverter by a control circuit 24. The compressor 4, consequently, is operated until its speed reaches to the n1, the maximum capacity of the compressor 4 is increased up to Q1 and heating capacity of the air conditioner can be controlled. Next to the above, when the temperature of the indoor unit 7 becomes lower than the fixed temperature Tc during the operation of the air conditioner under the speed n1, instructions commanding the inverter 21 that the maximum speed is to be made into n2 is given to the inverter 21 again by the controll circuit 24 and the maximum producible capacity of the compressor becomes operatable up to Q2.

INDUSTRIAL APPLICATION FIELD The present invention relates to a method for controlling the capacity of an air conditioner. Conventional configurations and their problems In general, Y-type air conditioners are used for indoor
A refrigeration cycle is constructed by connecting a pressure reducing device 3 and a compressor 4 to the heat exchanger 1 and the outdoor heat exchanger 2, and furthermore, a fan 5.6 is connected to the indoor heat exchanger 1 and the outdoor heat exchanger 2.
are provided opposite to each other, and the indoor unit 7 is provided with a temperature sensor 8 for detecting the degree of suction air. Reference numeral 9 indicates a control circuit, 10 indicates an outdoor unit, and 11 indicates a commercial power supply.By the way, the operation when the air conditioner having the above configuration is operated for heating will be explained with reference to FIG. The difference between the suction temperature in the room 7 detected by 8 and the temperature preset in the control 1111 circuit 9 is detected, and if the latter temperature is higher than the latter, the control circuit 9 outputs an ON signal. As a result, the compressor 4 is operated in synchronization with the commercial power supply 11 (/? power supply frequency. In this case, the outdoor cornit 10
The relationship between the temperature T and the heating capacity of the 11 air reading machines shown in Figure 1 is as shown in Figure 3. ..
As shown by characteristic A in FIG. 3, the relationship between outside air temperature and heating capacity when operating under relatively low air pollution tends to increase as outside air temperature rises. tt,'+"l'-
k C is the air conditioning load curve of indoor unit 7, and Shiki reading method 1
Contrary to the heating capacity of a single unit, it tends to decrease as the outside temperature rises. Here is the air conditioning load of the indoor UNISO 1-7! In the case shown by item C, the outside temperature is T. At the time of t;J, the heating capacity of the conventional air conditioner has a capacity adapted to the air conditioning load of the indoor unit. As the outside temperature rises, the difference between the air conditioning load of the indoor unit 7 and the heating capacity of the air conditioner increases, and the room temperature is adjusted by turning on and off the compressor according to the air conditioning load. . The following is a summary of the operation of the conventional nitrogen air conditioner 71]. If a person who is not familiar with the situation unnecessarily and erroneously sets the temperature in the control circuit 9 that exceeds the capacity required for the 91 load of the indoor unit 7, as mentioned above, the There is a tendency that the heating capacity of the indoor unit 7 increases as the outside temperature rises, and conversely, the 212 control load decreases as the outside temperature rises. The temperature is high at 19+'f. This will result in continuous rotation. In the flaming state -5, the user of the nitrogen air control fl1 machine (
Not only does it give a sense of waste and ash, but it also poses a problem in terms of energy conservation. However, conventionally, no measures have been taken to deal with this problem, and some kind of countermeasure is required. Day 1 of the Invention The present invention solves the above-mentioned conventional problems, which occur when the room temperature is set incorrectly. This is to prevent an abnormal rise in room temperature and the associated waste of 1IH4 energy. In order to achieve this objective, the present invention reduces the number of rotations of the compressor.

The temperature of unit 7 in the notification IJ recording room is a certain constant temperature Tc -
I-1! In the case of J, the control circuit 24 is [11 and 11
A command to set the maximum rotational speed of the compressor 4 to n2 is given to the J-book 21, and as a result, the compressor 4 is operated at its maximum output capacity up to Q2. The second operation is not shown in FIG. 3 and will be explained using characteristics B and D. At temperatures above Tc where the outside air temperature is relatively low, the H

g) The maximum ability of 1 Iso 4 is limited to 4. Below, in the case where the outside temperature is lower than To, the maximum rotational speed of the compressor 4 is similarly controlled.
In particular, it is possible to reduce the heating capacity of one air conditioner to one unit. Therefore, 4. +1' An elderly person who is unaccustomed to operating an air conditioner or a small child mistakenly sets the melting point during heating, causing the room temperature to rise to an abnormal 7! 1, the upper limit of the maximum capacity of the compressor 4 is limited by the inverter 21, so that the user does not feel uncomfortable due to an abnormal rise in room temperature.
In addition, it is possible to reliably prevent energy from being wasted or wasted unnecessarily. Effects of the Invention As is clear from the above embodiments, the method for controlling the capacity of an air conditioner according to the present invention provides a compressor constituting a refrigerating cycle with a bactericidal device that controls the rotation speed of the compressor. It is designed to limit the maximum capacity of the compressor by controlling the rotational speed of the machine, and this occurs when the air conditioner is operated with the indoor temperature set incorrectly during heating. By limiting the maximum ability of the compressor to handle an abnormal rise in room temperature, the user of the air conditioner can be prevented from feeling discomfort due to abnormal temperature. 1 In addition, it has the advantages of FL, including the fact that it has a great effect on energy conservation.
