Abstract

PURPOSE: To make effective use of a heat exchanger even if a thermo-controller is in an OFF state by taking such a measure as drives a variable wind direction louver when the thermo-controller is in an OFF state created by a room temperature controller, and moreover, while the temperature of the heat exchanger exceeds a specified temperature. CONSTITUTION: A centralized air conditioning system 1 drives an air supply motor 7 with a controller 5 during heating operation and turns a movable air direction louver 9 by driving a louver drive motor 8. During this operation, a room temperature controller 12 operates based on a detected signal of a room temperature sensor 11 so that the heating operation may come to a halt temporarily and thereby hold the room temperature to a setting temperature. The room temperature controller monitors the operation of the room temperature controller 12. For example, if the indoor equipment to be used is a thermo- controller in an OFF state, the rotary speed of the air supply motor 7 is reduced so that it may be driven in a weak mode. The controller 5 detects the temperature of a heat exchanger 6 based on a detected signal of a temperature sensor 10. In case when this detection signal is at least a reference temperature, for example, the drive of the movable wind director louver is continued.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will now be described with reference to the drawings.

FIG. 1 shows a schematic configuration diagram of the centralized heating and cooling system. In FIG. 1, for simplification of description, a case where two indoor units are connected to one outdoor unit will be described.

The centralized cooling and heating system 1 is roughly classified into an outdoor unit 2, two indoor units 4A and 4B connected to the outdoor unit 2 via a heat medium pipe 3, and the centralized cooling and heating system 1 as a whole. The control section 5 is provided.

The indoor units 4A and 4B have a heat exchanger 6 for exchanging heat, a blower motor 7 for blowing air, and a variable wind direction louver 9 driven by a louver driving motor 8 for wind direction control.
A temperature sensor 10 that detects the temperature in the vicinity of the heat exchanger 6 and outputs a temperature detection signal S _T ; and a room temperature sensor 11 that detects the temperature of the room in which the indoor unit is installed and outputs a room temperature detection signal S _RT. And a room temperature adjuster 12 that adjusts the room temperature based on the room temperature detection signal S _RT . a) Operation during heating operation Next, the operation during heating operation will be described with reference to the operation flowchart of FIG.

When the heating operation is started (step S1),
The control unit 5 drives the blower motor 7 to start blowing air, and drives the louver driving motor 8 to rotate the variable wind direction louver 9 to perform wind direction control (step S2).

By the way, during the heating operation, the room temperature regulator 12 operates based on the room temperature detection signal S _RT to temporarily stop the heating operation (turn off the thermostat) and maintain the room temperature at the set constant temperature. .

Therefore, the control unit 5 monitors the operation of the room temperature regulator 12 to determine whether or not the corresponding indoor unit is in the thermo-off state (step S3), and when it is in the thermo-on state (when the heating operation is in operation). (Step S3; N
o), the process proceeds to step S2.

If the thermostat is off (step S

For the indoor unit in which the temperature in the vicinity of the heat exchanger or the heat exchanger is lower than the first predetermined temperature, the louver drive means stops the variable air flow louver at a predetermined position. For the indoor unit in the thermo-off state by the room temperature controller during cooling, and the temperature of the heat exchanger or the vicinity of the heat exchanger is equal to or lower than a second predetermined temperature, the louver driving means of the indoor unit. The variable air flow louver is driven by the louver drive means for the indoor unit in which the temperature in the heat exchanger or in the vicinity of the heat exchanger is higher than the second predetermined temperature during the thermo-off state by the room temperature controller. A control device for stopping the variable wind direction louver at a predetermined position according to the above. 6. A plurality of indoor units are connected to one outdoor unit,
A control device for an air conditioner, wherein each of the indoor units is provided with a room temperature controller, a blower fan, a fan drive means for driving the blower fan, a variable wind direction louver, and a louver drive means for driving the variable wind direction louver. A temperature detecting means for detecting the temperature of the heat exchanger of each of the indoor units or the vicinity of the heat exchanger and outputting a temperature detection signal, and based on the temperature detection signal, the room temperature controller by the room temperature controller during heating. For the indoor unit that is in the thermo-off state and the temperature of the heat exchanger or in the vicinity of the heat exchanger is equal to or higher than a first predetermined temperature, the louver driving means of the indoor unit drives the variable wind direction louver. Driving the blower fan by the fan drive means of the indoor unit, while the heat exchanger is in the thermo-off state by the room temperature controller, For the indoor unit in which the temperature near the heat exchanger is lower than the first predetermined temperature, the louver driving means of the indoor unit stops the variable wind direction louver at a predetermined position, and the fan driving means of the indoor unit. The air blower fan is stopped by the above, and during the cooling, the indoor unit is in the thermo-off state by the room temperature controller and the temperature of the heat exchanger or the vicinity of the heat exchanger is the second predetermined temperature or less. Driving the variable airflow direction louver by the louver driving means of the indoor unit, driving the blower fan by the fan driving means of the indoor unit, and heating the fan while the thermostat is off by the room temperature controller. For the indoor unit whose temperature in the vicinity of the exchanger or the heat exchanger is higher than the second predetermined temperature, the louver driving means of the indoor unit is used. Further, the control device for stopping the variable wind direction louver at a predetermined position and for stopping the blower fan by the fan driving device of the indoor unit, is provided.
