Abstract

An air conditioning system includes: an air conditioner that includes an outdoor unit including an outside air temperature sensor and an indoor unit including an indoor unit controller to control air conditioning operation and communicable with the outdoor unit; and a remote controller communicable with the indoor unit. The remote controller includes: a schedule storage to store information on an operation schedule of the air conditioner for each date and time, a reference temperature for determining an operation mode of the air conditioner, and an outside air temperature correction value; and an operation mode determiner to select the operation mode from among cooling, blowing, and heating using the information on the operation schedule, a corrected outside air temperature, and the reference temperature. The indoor unit controller controls the air conditioning operation using the reference temperature as a target temperature in the operation mode determined by the operation mode determiner.

First claim

The invention claimed is:

1. An air conditioning system comprising:
an air conditioner that includes an outdoor unit including an outside air temperature sensor to detect an outside air temperature and an indoor unit including an indoor unit controller to control air conditioning operation, the indoor unit being communicable with the outdoor unit; and
a remote controller communicable with the indoor unit,
wherein
the remote controller includes:
a schedule storage to store information on an operation schedule of the air conditioner for each date and time set in advance, a reference temperature for determining an operation mode of the air conditioner, and an outside air temperature correction value for correcting the outside air temperature; and
an operation mode determiner to select the operation mode from among cooling, blowing, and heating using the information on the operation schedule, a corrected outside air temperature obtained through correction of the outside air temperature with the outside air temperature correction value, and the reference temperature,

the indoor unit controller controls the air conditioning operation using the reference temperature as a target temperature in the operation mode determined by the operation mode determiner, and
the operation mode determiner is configured to:
calculate a cooling selection temperature that is the corrected outside air temperature for selecting the cooling as the operation mode by adding the outside air temperature correction value to the outside air temperature and a heating selection temperature that is the corrected outside air temperature for selecting the heating as the operation mode by subtracting the outside air temperature correction value from the outside air temperature;
determine that a first condition is satisfied when the reference temperature is lower than the cooling selection temperature;
determine that a second condition is satisfied when the reference temperature is higher than the heating selection temperature;
select the cooling as the operation mode when the reference temperature satisfies the first condition but does not satisfy the second condition;
select the heating as the operation mode when the reference temperature satisfies the second condition but does not satisfy the first condition; and
select the blowing as the operation mode when the reference temperature satisfies the first condition and the second condition.

2. The air conditioning system according to claim 1 , wherein
the indoor unit includes an indoor temperature sensor to detect an indoor temperature, and
the operation mode determiner determines the operation mode using the information on the operation schedule, the corrected outside air temperature, a temperature difference between the outside air temperature and the indoor temperature, and the reference temperature.

3. The air conditioning system according to claim 1 , wherein:
the remote controller further includes a display configured to display information and conditions required for air conditioning by the air conditioner, and
the remote controller is formed to be a single device.

4. The air conditioning system according to claim 1 , wherein:
the remote controller further includes an operation circuit configured to accept setting operations from a user, and
the remote controller is formed to be a single device.

5. The air conditioning system according to claim 4 , wherein:
the operation circuit further includes one or more operation buttons configured to be pressed by a user to set operational information for the air conditioning system.

6. The air conditioning system according to claim 1 , wherein:
the remote controller further includes a clock function circuit configured to identify at least one of a current day of the week, a current date, and a current time, and
the remote controller is formed to be a single device.

7. The air conditioning system according to claim 1 , wherein:
the cooling selection temperature is set to be equal to the outside air temperature plus the outside aft temperature correction value; and
the heating selection temperature is set to be equal to the outside air temperature minus the outside air temperature correction value.

8. The air conditioning system according to claim 1 , wherein:
the indoor unit further includes an indoor temperature sensor to detect an indoor temperature;
the operation mode determiner is further configured to calculate a temperature difference by subtracting the outside air temperature from the indoor temperature;
the cooling selection temperature is set to be equal to the outside air temperature plus the sum of the outside air temperature correction value and the temperature difference; and
the heating selection temperature is set to be equal to the outside air temperature minus the sum of the outside air temperature correction value and the temperature difference.
