Abstract
According to the present disclosure, it is determined whether or not the room is heated according to a temperature difference between a room temperature Tp and a set temperature Ts, and even when there is little or no heating load due to the temperature difference between the room temperature Tp and the set temperature Ts, the floor heating is performed by determining a temperature difference between the room temperature Tp and a floor temperature Tb.
Claims20
A control method of a ceiling type indoor unit including a case which is installed to be suspended to a ceiling of a room, includes a suction port formed on a bottom surface, and includes a first discharge port and a third discharge port disposed to face each other based on the suction port and a second discharge port and a fourth discharge port disposed to face each other based on the suction port,
- a first vane module which is disposed in the first discharge port, constitutes one of a first discharge pair, and discharges air in a first discharge direction,
- a second vane module which is disposed in the second discharge port, constitutes one of a second discharge pair, and discharges air in a second discharge direction,
- a third vane module which is disposed in the third discharge port, constitutes the other one of the first discharge pair, and discharges air in a third discharge direction, and
- a fourth vane module which is disposed in the fourth discharge port, constitutes the other one of the second discharge pair, and discharges air in a fourth discharge direction,
- the control method comprising:
- a step S10 of turning on a cooling mode;
- a temperature setting step S12 of, after Step S10, sensing a room temperature Tp and a floor temperature Tb and receiving a set temperature Ts;
- a step S14 of, after Step S12, comparing the room temperature Tp and the set temperature with each other;
- a step S20 of, in a case where the room temperature Tp is less than the set temperature Ts, operating at least on of the first discharge pair and the second discharge pair at one inclination angle;
- a step S32 of, after Step S20, comparing a temperature difference between the room temperature Tp and the floor temperature Tb with a first reference value A;
- a step S34 of, in a case where the temperature difference exceeds the first reference value A after Step S32, operating at least one of the first discharge pair and the second discharge pair at another inclination angle;
- a step S100 of, after Step S34, determining whether or not the heating mode is turned off;
- and
- a step of, in a case where Step S100 is satisfied, ending the heating mode, and
- in a case where the room temperature Tp is equal to or more than the set temperature Ts after Step S14, the step proceeds to Step S32, and another inclination angle is disposed more vertically in an up-down direction than the one inclination angle.
