Abstract

An air conditioner with a radiant temperature control comprises a refrigeration cycle for air-conditioning a room to be air conditioned at a desired temperature, a temperature setting section for generating set data for setting the desired temperature as a target value, a first temperature sensor section for detecting a room temperature of the room to be air-conditioned, a second temperature sensor section for detecting a radiant temperature of the room to be air-conditioned, a control section for receiving the set data from the temperature setting section and detection data from the first temperature sensor section and for generating an operation control signal to the refrigeration cycle in accordance with the difference therebetween, and a correcting section for receiving the set data from the temperature setting section and detection data from the second temperature sensor section and, when the difference therebetween deviates from a predetermined value, correcting the set data from the temperature setting section in accordance with the deviation of the difference between the set data and the detection data from the predetermined value.

Claims

1. An air conditioner with a radiant temperature control comprising:

a refrigeration cycle for air-conditioning a room at a desired temperature;

temperature setting means for setting the desired temperature at a target value;

first temperature sensor means for detecting an air temperature of the room;

second temperature sensor means for detecting a radiant temperature of the room;

control means for receiving the target value from said temperature setting means and the air temperature from said first temperature sensor means and for outputting an operation control signal to said refrigeration cycle in accordance with a difference between said target value and said air temperature; and

correcting means for receiving the target value from said temperature setting means and the radiant temperature from said second temperature sensor means, and when a difference therebetween deviates from a predetermined value, correcting the target value from said temperature setting means in accordance with a deviation of the difference between the target value and the radiant temperature from the predetermined value.

2. An air conditioner according to claim 1, wherein the predetermined value is selected such that a temperature deviation is not perceived by a person within the room.

3. An air conditioner according to claim 1, wherein said correcting means corrects the target value from said temperature setting means by shifting the target value to a new target value which is a predetermined number of shift steps from said target value, each shift step corresponding to a predetermined temperature increment.

4. An air conditioner with a radiant temperature control comprising:

a heat exchange cycle for air-conditioning a room at a desired temperature in a cooling or heating mode;

operating means for setting said heat exchange cycle in the cooling or the heating mode and for setting the desired temperature at a target value;

first temperature sensor means for detecting an air temperature of the room;

second temperature sensor means for detecting a radiant temperature of the room;

control means for receiving the target value from said operating means and the air temperature from said first temperature sensor means and for outputting an operation control signal to said heat exchange cycle in accordance with a difference between said target value and said air temperature; and

correcting means for receiving the target value from said operating means and the radiant temperature from said second temperature sensor means and, when a difference therebetween deviates from a predetermined value, correcting the target value from said operating means in accordance with a deviation of the difference betwen the target value and the radiant temperature from the predetermined value and in accordance with the cooling or heating mode set in said heat exchange cycle.

5. An air conditioner according to claim 4, wherein said first and second temperature sensors are arranged so as to cancel adverse influences of heat generated by said control means.
