Title:
空気調和装置
Document Type and Number:
Japanese Patent JP6468300
Kind Code:
B2
Abstract:
An air conditioner capable of displaying sufficient cooling ability in each indoor unit is provided by allowing a sufficient amount of refrigerant to flow into indoor units where cooling ability cannot be displayed.If the refrigerant amount balance control is executed, since degrees of opening of indoor expansion valves 52a, 52b are narrowed in indoor units 5a, 5b whose refrigerant superheating degrees are smaller than an average refrigerant superheating degree, amounts of refrigerant flowing into the indoor expansion valves 52a, 52b are decreased. On the other hand, in the indoor unit 5c where the refrigerant superheating degree is higher than the average refrigerant superheating degree, since refrigerant pressure on a downstream side of the indoor expansion valve 52c is also decreased due to the degrees of opening of the indoor expansion valves 52a, 52b being narrowed, the difference in pressure between the upstream side and the downstream side of the indoor expansion valve 52c increases and an amount of refrigerant flowing into the indoor unit 5s is increased. Accordingly, cooling ability of the indoor unit 5c increases.
