摘要： PROBLEM TO BE SOLVED: To provide an air conditioner capable of performing operation of another indoor unit without causing dew condensation, freezing or leak of a heat exchanger even if the power supply to a part of indoor units is interrupted. SOLUTION: The air conditioner comprises a transmission line power source 16 connected to a transmission line 5 to supply power to each indoor unit 2 or 3; refrigerant circuit interrupting means 21 and 41 for adjusting or interrupting the refrigerant quantity carried into and carried out of each indoor unit; service interruption detection means 30 and 50 for detecting the interruption of power supply to each indoor unit; transmission line power receiving means 29 and 49 for receiving the power capable of ensuring at least the communicating function by the transmission line and the driving function of the refrigerant circuit interrupting means even if the power supply to the indoor units is interrupted; refrigerant circuit interruption control means 34 and 54 for operating the refrigerant circuit interrupting means, when the power supply interruption is detected by the service interruption detection means, to interrupt the inflow of the refrigerant to the indoor units or the outflow of the refrigerant from the indoor units; and an operation control means 10 for continuing the operation of an outdoor unit even when the power supply interruption of a part of the indoor units is detected.

摘要： PROBLEM TO BE SOLVED: To solve the problem of a current refrigeration cycle system that performance thereof is lowered by a pressure loss by the liquid head in the case of installation in a multistory building having a large height difference. SOLUTION: This refrigeration cycle system is provided with a first refrigeration cycle having high-pressure piping and low-pressure piping in a direction crossing floors of the multistory building and a second refrigeration cycle having gas pipes and liquid pipes in the floor-direction of the predetermined story. This refrigeration cycle system also has a first intermediate heat exchanger provided in a piping, which is annularly connected to the high-pressure piping, to exchange the heat between the first refrigeration cycle and the second refrigeration cycle during the warm-up operation, and a second intermediate heat exchanger provided in a piping, which is annularly connected to the low-pressure piping, to exchange the heat between the first refrigeration cycle and the second refrigeration cycle during the cooling operation.

IPC分类号： F24F11/02
摘要： PROBLEM TO BE SOLVED: To solve a problem of a conventional air conditioner when a trouble occurs that a user resets only a problematic parameter without comprehensively resetting other influenced parameters, thereby the air conditioner is not always suitable to the use environment. SOLUTION: A remote centralized controller generates suitable control parameters based on setting condition data input by the user after installing the air conditioner. A heat source, and a control program included in an indoor unit operate according to the control parameters. COPYRIGHT: (C)2004,JPO

IPC分类号： F24F11/02
摘要： PROBLEM TO BE SOLVED: To provide an air-conditioner enabling to perform good communication without detecting a transmission signal in error even when a great induction load occurs between transmission lines. SOLUTION: The air-conditioner for performing AMI-system communication comprises a transmission means 22 for transmitting a AMI-system pulse signal to a transmission path, and a transmission backswing cancel pulse output means for outputting a pulse current having polarity the reverse of the pulse signal after the transmission means 22 transmits the pulse signal.
