Abstract

PURPOSE:To make the reduction of decreasing of an indoor temperature possible when a thermostat is turned off by a method wherein the detecting error of a detected indoor temperature is corrected and thermostat-ON operation is effected upon heating operation thermostat is turned off. CONSTITUTION:An air-conditioning machine 1 is divided into an indoor side and an outdoor side. An indoor control unit 2 in the indoor side is connected to an indoor temperature detecting unit 3 to detect an indoor temperature by the indoor temperature detecting unit 3 while the indoor control unit 2 sets the indoor temperature by a signal from an indoor temperature setter 4. On the other hand, the indoor control unit 2 sends signals to an indoor fan 5 and an outdoor control unit 6 based on the indoor temperature detecting signal and the indoor temperature setting signal to control a compressor 7 and an outdoor fan 8 and turns a thermostat on/off. The detecting error of the detected indoor temperature, detected by the indoor temperature detector 3, is corrected when a heating operation thermostat is off and thermostat-ON operation is effected. By this method, the reduction of the indoor temperature when the thermostat is turned off is restricted and comfortability for inhabitants can be improved.

According to the above-mentioned conventional technique, the thermostat is turned on and off based on the indoor temperature detected by the indoor temperature detecting means to maintain the indoor temperature at the set temperature. To do. Here, when the thermostat is normally OFF, the compressor is stopped, so the indoor blower is stopped or operated at a very low rotational speed to prevent the occupants from feeling a cold wind. For this reason, the heat inside the thermostat is accumulated near the indoor temperature detecting means, and the indoor temperature cannot be accurately detected. Therefore, even though the room temperature is actually lower than the set temperature during the thermo-off, the room detected temperature detected by the room temperature detecting means becomes a value higher than the set temperature, and the thermo-ON is not performed. After that, as the indoor temperature further decreases, the indoor detected temperature detected by the indoor temperature detecting means becomes a value lower than the set temperature, and the thermostat is finally turned on. As described above, the room temperature during the thermo-OFF is lower than the set temperature, which causes discomfort to the occupants. The present invention has been made in order to solve the problems of the prior art, and is a control for correcting the indoor detected temperature detected by the indoor temperature detecting means and turning on the thermostat based on the correction.

During the heating operation, the indoor detected temperature T 1 detected by the indoor temperature detector 3 is preset to the indoor temperature setting device 4 in advance.
When the indoor set temperature T 2 set by the above exceeds T 2 ′ obtained in consideration of the differential amount, the compressor 7 and the indoor blower 6 are stopped and the thermostat is turned off. After that, the indoor temperature T 0 begins to decrease, but the indoor detected temperature T 1 detected by the indoor temperature detector 3 at this time becomes a higher value than the actual indoor temperature T 0 due to the effect of accumulated heat. This value is corrected and used for thermo ON determination. One of the modifications is, as shown in Fig. 2, the time after the thermostat is turned off.
After the elapse of t, the actual indoor temperature T 0 is equal to the indoor set temperature T 2
This is a method of forcibly turning on the thermostat regardless of the value of the indoor detected temperature T 1 detected by the indoor temperature detector 3 presumed to have fallen to some extent. Where time △
It is appropriate to control the value of t to a value that takes into consideration the change in the room temperature according to the size of the room, the indoor set temperature, the outside air temperature, and the like. However, even if the temperature is set to a constant value, it is possible to prevent a decrease in the room temperature when the thermostat is turned off, as compared with the conventional technique shown in FIG. 2, under most conditions in which the heating operation is actually performed. If the control of the present embodiment is carried out as it is, the thermostat is forcibly carried out even if the actual room temperature T 0 is higher than the indoor set temperature T 2 , but in this case,
Once the thermostat is turned on, the thermostat is turned off after continuing the heating operation for at least 3 minutes to protect the compressor 7 normally. Therefore, by repeating this operation, the indoor temperature T 0 is significantly higher than the indoor set temperature T 2. Will end up. Therefore, in order to prevent this, when the indoor detected temperature T 1 detected by the indoor temperature detector 3 when the thermostat is turned off is 1 to 2 ° C. higher than the indoor set temperature T 2 , It is necessary not to execute this control.
