An air-conditioning device including multiple outdoor units and an indoor unit through a pipe includes a control section that obtains a degree of subcooling at an outlet of a subcooling circuit of each outdoor unit based on a temperature detected by a temperature sensor that detects the temperature of refrigerant having passed through the subcooling circuit of each outdoor unit, obtain a target value of the degree of subcooling based on the obtained multiple degrees of subcooling, and perform the control of increasing the rotation speed of a compressor of an outdoor unit having a higher degree of subcooling than the target value and decreasing the rotation speed of a compressor of an outdoor unit having a lower degree of subcooling than the target value such that a difference in the degree of subcooling at the outlet of the subcooling circuit of each outdoor unit is decreased.

Air-conditioning device

To achieve higher efficiency at a low-load region and to enable power saving throughout a year. The refrigeration cycle apparatusincludes a compressorthat has a flow in/out portthrough which a refrigerant is capable of flowing out and flowing in, in fluid communication with a compression room; pipesdisposed at a suction side of the compressor; a pipeconnected to the flow in/out portof the compressor; a pipethat has one end connected to the pipeand an opposite end connected to the pipe; and a second solenoid valvefor opening and closing a fluid passage of the pipe

Refrigeration cycle apparatus

An air conditioner is provided, which is capable of accurately determining appropriateness of a refrigerant amount in a refrigerating cycle. A control apparatus is configured to: stop a cooling operation; set an expansion valve to a fully-closed state and, at the same time, switch the selector valve to change the direction, in which a refrigerant flows, to an opposite direction; operate a compressor to perform a refrigerant recovery operation, in which a refrigerant contained in an outdoor heat exchanger is recovered by an indoor heat exchanger; and determine the appropriateness of a refrigerant amount in a refrigerating cycle, based on at least one of a time required for recovering the refrigerant, a pressure change in a refrigerant suctioned by the compressor, and temperature of the refrigerant discharged from the compressor during the refrigerant recovery operation.

Air conditioner

The air conditioner has: an outdoor heat exchanger that exchanges heat between the air and a refrigerant flowing in the interior of this heat exchanger; an outdoor fan that blows air into the outdoor heat exchanger; an outdoor fan motor that rotationally drives the outdoor fan; an outdoor fan inverter that supplies a desired current to the outdoor fan motor; a current detector that detects the current flowing in the outdoor fan motor; and a control unit that controls the outdoor fan inverter such that the rotational frequency of the outdoor fan motor reaches a target rotational frequency. The control unit starts a defrosting operation of the outdoor heat exchanger on the basis of a detection value from the current detector during the heating operation.

A sterile composition which comprises a protein and an aliphatic polyester containing the protein and is sterilized with radiation. In this sterile composition, the structure and function (activity) of the protein are retained.

Sterile composition

An object to be achieved by the invention is to provide a biodegradable low-charging fiber. The prevent inventors have found that when a specific amount of a specific phospholipid that is not known to have antistatic properties is added to a biodegradable polymer, and the resulting mixture is formed into a fiber having a smooth surface, low-charging properties are developed. The invention has thus been accomplished. The invention is a fiber having an average surface porosity of less than 3% and made of a biodegradable polymer that contains a specific amount of a specific phospholipid.

Low-charging fiber and method for producing the same
