Startup control apparatus of air conditioner

摘要

An air conditioner performs startup control in which compressor capacity is reduced as measured indoor temperature approaches a set temperature. A desired time of day is set directly or indirectly. A startup control apparatus of the air conditioner measures an inflection point occurrence time from when the air conditioner starts operation until when measured indoor temperature exhibits an inflection point. Alternatively, the startup control apparatus measures a control parameter lowering arrival time from when the air conditioner starts operation until when a control parameter transmitted to the compressor decreases to a prescribed value. A scheduled operation start time of the air conditioner is set as a time of day that is the desired time of day set moved forward by the inflection point occurrence time or the control parameter lowering arrival time. Operation of the air conditioner is started when the scheduled operation start time arrives.

主权项

1. A startup control apparatus of an air conditioner that performs startup control of the air conditioner in which capacity of a compressor is automatically reduced as an indoor temperature approaches a set temperature to bring the indoor temperature close to the set temperature, the startup control apparatus comprising:
a desired time setting unit configured to set a desired time of day directly or indirectly; an indoor temperature measuring unit configured to measure the indoor temperature; an inflection point occurrence time measuring unit configured to measure an inflection point occurrence time, which is a time from when the air conditioner starts operation until when a measured indoor temperature measured by the indoor temperature measuring unit exhibits an inflection point, the inflection point being a first point in which a sign of a slope value of the indoor temperature changes by automatically and gradually reducing the capacity of the compressor in the startup control of the air conditioner as the indoor temperature approaches the set temperature to bring the indoor temperature close to the set temperature; an air conditioning operation scheduled start time determining unit configured to set as a scheduled operation start time of the air conditioner a time of day that is the desired time of day set by the desired time setting unit moved forward by the inflection point occurrence time; and a startup control unit configured to start a subsequent start operation of the air conditioner when the scheduled operation start time set by the air conditioning operation scheduled start time determining unit arrives.
