Air conditioner having a variable speed indoor side blower and flaps being control based on outside air temperature and indoor heat exchanger temperature

摘要

There is disclosed an air conditioner which can realize appropriate air conditioning control in a situation closer to a feeling temperature even in a case where a floor surface of a room to be conditioned is low. The air conditioner which blows air subjected to heat exchange between the air and a user side heat exchanger into a room to be conditioned by an indoor side blower comprises a user side controller which controls a revolution speed of the indoor side blower based on the present temperature in the room and a set temperature, and this controller raises the revolution speed of the indoor side blower in a case where an outside air temperature is not higher than a predetermined revolution speed rise temperature during a heating operation.

主权项

1. An air conditioner which blows air subjected to heat exchange between the air and an indoor side heat exchanger into a room to be conditioned by an indoor side blower, comprising:
a controller which controls a revolution speed of the indoor side blower based on the present temperature of the room to be conditioned and a set temperature, wherein the controller raises the revolution speed of the indoor side blower in a case where an outside air temperature is not higher than a predetermined revolution speed rise temperature during a heating operation, wherein the controller sets a revolution speed rise amount of the indoor side blower to a maximum value in a case where the outside air is not higher than a predetermined maximum rise temperature, which is lower than the predetermined revolution speed rise temperature, and the controller lowers the revolution speed rise amount of the indoor side blower as the outside air temperature rises to the predetermined revolution speed rise temperature, in a case where the outside air temperature is higher than the predetermined maximum rise temperature, wherein the controller corrects the set revolution speed rise amount of the indoor side blower determined based on the outside air temperature in such a direction as to lower the revolution speed rise amount in a case where a temperature of the indoor side heat exchanger is not higher than a predetermined hot air compensation temperature, and wherein the controller sets the revolution speed rise amount of the indoor side blower to zero in a case where the temperature of the indoor side heat exchanger is not higher than a predetermined cold air limitation canceling temperature which is lower than the predetermined hot air compensation temperature, and the controller decreases correction of the revolution speed rise amount of the indoor side blower as the temperature of the indoor side heat exchanger rises to the predetermined hot air compensation temperature, in a case where the temperature of the indoor side heat exchanger is higher than the predetermined cold air limitation canceling temperature.
