摘要： PROBLEM TO BE SOLVED: To provide a compressor and an air conditioner capable of preventing a piston from being locked by a frozen material in a cylinder. SOLUTION: In a compressor operation control part 18 of a control device 12, a piston 2 is stopped in a high temperature region HR in which the temperature is relatively high to resist generation of frost or ice on the inner peripheral surface of the cylinder 1. By so doing, no frozen material is generated between the high temperature region HR of the inner peripheral surface of the cylinder 1 and the piston 2 so as to prevent the piston from being locked by the frozen material.

摘要： PROBLEM TO BE SOLVED: To provide an air conditioner and its control method for properly controlling a temperature even when an actual opening of an electrically operated expansion valve and an opening recognized by a control part controlling the electrically operated expansion valve are separated from each other.
SOLUTION: This air conditioner comprising a refrigerant circuit successively connecting a compressor, an outdoor heat exchanger, the electrically operated expansion valve and an indoor heat exchanger, further comprises a discharge temperature sensor and the control part. The discharge temperature sensor detects the discharge temperature at a discharge side of the compressor. The control part changes the opening of the electrically operated expansion valve on the basis of a first limit value UL1 to make the discharge temperature approximate a target value, and further changes the opening of the electrically operated expansion valve on the basis of a second limit value UL2 over the first limit value, when the discharge temperature does not approximate the target value, though the opening of the electrically operated expansion valve reaches the first limit value UL1.

摘要： PROBLEM TO BE SOLVED: To provide a compressor and an air conditioner preventing a piston from being locked in a cylinder by a freezing body. SOLUTION: A compressor operation control part 18 of a control device 20 stops the piston 2 in a high temperature region HR where temperature is relatively high and frost or ice is not easily formed on an inner circumference surface of the cylinder 1. Consequently, the piston 2 is prevented from being locked by the freezing body since the freezing body is not formed between the piston 2 and the high temperature region HR of the cylinder 1.

摘要： PROBLEM TO BE SOLVED: To provide an air conditioner having a humidifying function in which a humidifier can be provided and also a trap for treating water in humid air conveying piping can be readily provided without making large the floor area for an outdoor unit. SOLUTION: A humidifier 2 for desorbing outdoor moisture adsorbed by an adsorption material and for supplying the desorbed moisture to an indoor unit 1, is arranged at an upper portion of the outdoor unit 1. A humidifying rotor 5 serving as the adsorption material is disposed in the humidifier 2 so that an axis 6 is substantially positioned along the vertical direction to reduce the height of the humidifier 2. Humid air conveying piping 4 for conveying humid air from the humidifier 2 to an outdoor unit 3, is extended downward from the humidifier 2 along a side surface 1a of the indoor unit 1, and further extended upward from the lower portion of the side surface 1a of the indoor unit 1 so as to be connected to the outdoor unit 3.

摘要： PROBLEM TO BE SOLVED: To provide an air conditioner which can raise the comfortableness of indoor space, by suppressing the breeding of a variety of bacteria inside an indoor machine. SOLUTION: In a heat pump system of air conditioner which is capable of air conditioning operation, being equipped with an indoor machine 3 and an outdoor machine 2, the indoor heat exchanger 7 of the indoor machine 3 is made to function as a condenser so as to execute a sterilizing mode which keeps a certain temperature (60 deg.C) above the temperature where the bacteria such as mold, ticks, etc., can grow for a specified time (six minutes). This annihilates a variety of bacteria within the indoor machine 3 to reduce the number, and also accelerates the evaporation of the moisture inside the indoor machine 3.

摘要： PROBLEM TO BE SOLVED: To reduce the sound of a shock at the time of switching by a method wherein when a low noise is required, a control means makes a stopping period of time for a compressor at least at one of the times when the operation is switched from a heating to a defrosting, or from the defrosting to the heating, longer than normal. SOLUTION: When there is no requirement for a low noise by a control means, a compressor is driven by a normal frequency, and in the meantime, when is a requirement for a defrosting at a time t1 , the compressor stops extending to a period of time T1 , and a switching is performed at a time of t3 , and the compressor is re-started, and a defrosting operation is performed, and from a time t2 , when the frosting is dissolved, extending to a period of time T2 , the compressor is stopped again, and is re-started again at a time t4 , and the operation is returned to a heating operation. When there is a requirement for a low noise, the compressor is driven by a limited frequency, and in the meantime, when there is a requirement for a deforesting at a time t1 , the compressor is stopped extending to a period of time T1 which is about twice longer than a normal time, and is re-started at a time t3 , and performs a defrosting operation, and is stopped again from a time t2 when the defrosting is dissolved, extending to a period of time T2 which is about 1.5 times longer than the time of a normal operation, and is reset at a time t4 , and is re-started again, and is returned to a heating operation.
