Capacity control of heat pump type air conditioner

Abstract

Abstract PURPOSE: To shorten the rising time of the heating temperature at the time of heating operation of the heat pump type air conditioner by a method wherein not only the room temperature but also the wall temperature are constantly detected and even when the room temperature exceeds a target room temperature value, the heating operation is continued to thereby heat the inner wall of the room. CONSTITUTION: An auxiliary adjuster 15 gives to a main adjuster 14a value higher than the target room temperature value θ 1 as a newly set temperature value θ 2 for a period from the initiation of the heating operation up to a time T 3 because the difference between the wall temperature and the target value θ 1 is higher than a preset value (Δθ). Therefore, even when the room temperature reaches the original target value θ 1 , the air conditioner continues its heating operation so that heat meeting the heat capacity of the inner wall of the room is radiated into the room to thereby guarantee the heat radiation from the wall. Next, when the time T 3 is reached, the inner wall of the room is heated sufficently so that the difference between the wall temperature and the target room temperature θ 1 becomes equal to the set value Δθ. Accordingly, the auxiliary adjuster 15a varies the set value θ 2 to give the main adjuster 14a the target value θ 1 and as a matter of course, the room temperature becomes higher than the target value θ 1 to thereby stop the heating operation of the air conditioner.
