摘要： An air conditioner control apparatus measures coolant temperatures and pressures at both inlet side and outlet side of a compressor, or detects a electric capacity of the coolant and the like in order to determine the kind of coolant. For example, when a CPU 31 detects that the coolant R22 is used, the apparatus selects a data item of a fluorocarbone-based coolant R22 stored in a data selection means 35 storing pressure-temperature data items, and calculates a super-heated rate or a super-cooled rate according to the ability of a compressor 1 so that the room temperature reaches the predetermined one set by the operator and setting a calculation result.

摘要： An air conditioner employs a non-azeotropic refrigerant mixture without deteriorating the heat-exchange efficiency and air-conditioning capability of an indoor heat exchanger of the air conditioner. The indoor heat exchanger (3) has a fin on which a first path (33), a second path (34), and a third path (35) for passing the refrigerant mixture are arranged. The first path passes the refrigerant mixture from the leeward side toward the windward side of an air flow produced by an indoor fan (7), to form a counterflow of the refrigerant mixture against the air flow. The second path passes the refrigerant mixture from the windward side toward the leeward side of the air flow. Although the second path forms a parallel flow of the refrigerant mixture with respect to the air flow, it achieves moderate heat-exchange efficiency because the number of rows of piping on the leeward side is greater than that on the windward side and because the rows of piping do not overlap one another with respect to the air flow. The third path passes the refrigerant mixture from the windward side toward the leeward side and again from the windward side toward the leeward side of the air flow, to partly realize a counterflow of the refrigerant mixture against the air flow, to thereby improve the heat-exchange efficiency.

摘要： An air conditioner having a compressor, an outdoor fan, and two indoor heat exchangers which are connected by an electric expansion valve. During a dehumidifying operation, the opening of the electric expansion valve is decreased, thereby decompressing the refrigerant flowing from the first indoor heat exchange into the second indoor exchanger. The first and second heat exchangers thereby function as a reheater and an evaporator, respectively. The second indoor heat exchanger cools and dehumidifies the indoor air, and the first indoor heat exchanger heats the indoor air again. The indoor air, first cooled, then dehumidified, and finally re-heated, is supplied into the room. During the dehumidifying operation, a deviation (T) of the indoor temperature (Ta) from a preset indoor temperature (Ts), and a change (.DELTA.T) in the deviation (T) are detected, and the deviation (H) of the indoor humidity (Ha) from a preset indoor humidity (Hs), and a change (.DELTA.H) are also detected. Fuzzy inference is performed based on the deviation (T), the change (.DELTA.T), the deviation (H) and the change (.DELTA.H), thereby calculating an adjustment value (.DELTA.F) and an adjustment value (.DELTA.N). The value (.DELTA.F) adjusts the drive frequency of the compressor, and the value (.DELTA.N) adjusts the rotational speed (N) of the outdoor fan.
