摘要:
To a refrigerant circuit of an air conditioner as a refrigerating apparatus, a plurality of outdoor units are connected. In an operation state where the first outdoor unit is operated with the second outdoor unit stopped, the air conditioner performs refrigerant collection operation for collecting and retaining surplus refrigerant to and in a second outdoor heat exchanger of the second outdoor unit. During the refrigerant collection operation, a second outdoor expansion valve is closed fully, and a second outdoor fan is operated. Part of refrigerant discharged from a first compressor flows into the second outdoor heat exchanger during the refrigerant collection operation. The refrigerant flowing in the second outdoor heat exchanger dissipates heat to outdoor air to be condensed. Since the second outdoor expansion valve is closed fully, the condensed refrigerant is retained in the second outdoor heat exchanger.

An outdoor unit (20) including a compressor (21) and an outdoor heat exchanger (22) and an indoor unit (30) including an indoor heat exchanger (31) are provided. The outdoor unit (20) and the indoor unit (30) constitute a main circuit (43) of a refrigerant circuit (40). A sub-circuit (70) whose one end is connected to a liquid line (4a) of the main circuit (43) and another end is connected to a low-pressure gas line (4b) of the main circuit (43), and which stores refrigerant in the main circuit (43) is also provided. The sub-circuit (70) is located on a sub-passageway (71), and includes: a refrigerant regulator (72) for storing refrigerant in the main circuit (43); and a switch mechanism (73) for establishing and blocking communication between the refrigerant regulator (72) and each of the liquid line (4a) and the low-pressure gas line (4b). When the amount of refrigerant in the main circuit (43) is excessive, redundant refrigerant in the main circuit (43) is stored in the refrigerant regulator (72).

To a refrigerant circuit (20) of an air conditioner (10) as a refrigerating apparatus, a plurality of outdoor units (30, 40) are connected. In an operation state where the first outdoor unit (30) is operated with the second outdoor unit (40) stopped, the air conditioner (10) performs refrigerant collection operation for collecting and retaining surplus refrigerant to and in a second outdoor heat exchanger (42) of the second outdoor unit (40). During the refrigerant collection operation, a second outdoor expansion valve (43) is closed fully, and a second outdoor fan (46) is operated. Part of refrigerant discharged from a first compressor (31) flows into the second outdoor heat exchanger (42) during the refrigerant collection operation. The refrigerant flowing in the second outdoor heat exchanger (42) dissipates heat to outdoor air to be condensed. Since the second outdoor expansion valve (43) is closed fully, the condensed refrigerant is retained in the second outdoor heat exchanger (42).

The present invention provides a heat source unit capable of being used in either an air conditioner for switchable cooling and heating operation or an air conditioner for simultaneous cooling and heating operation. An air conditioner principally includes one heat source unit, a plurality of utilization units, and a connecting unit provided for each utilization unit. The heat source unit uses water as the heat source, and principally includes a compressing means, a main heat exchanger, a first switching means, a main refrigerant switching means, an auxiliary heat exchanger connected in parallel with the main heat exchanger, a second switching means, an auxiliary refrigerant switching means, and a liquid receiver. The auxiliary heat exchanger is capable of switching between functioning as an evaporator and a condenser, by the second switching means.

A system and method for enabling an audio conference server (ACS) to provide an application program with multi-point weight controllable audio conferencing. The ACS manages a plurality of audio conferences, receives audio data from a plurality of audio clients, mixes the audio data to provide distance-based attenuation according to decay characteristics for each sound, and delivers the mixed audio data to a plurality of audio clients. Audio clients include set-top box (STB) audio clients and point source audio (PSA) audio clients. The ACS mixes the audio data by identifying a decay factor. Pre-defined decay factors include an audio big decay factor, an audio small decay factor, an audio medium decay factor, and a constant decay factor. One can also develop a customized decay factor. A weighted value for a source audio client based on the identified decay factor and the distance between the source audio client and a target audio client is determined. A mix table is generated using the weighted values for each source/target audio client pair. Then an actual mix value for each target audio client is calculated using the mix table. The present invention also includes means for refining the actual mix value.

A refrigeration system to increase the subcooling degree of refrigerant flowing through a main refrigerant circuit is provided. The refrigeration system is configured such that a portion of the refrigerant flowing through the main refrigerant circuit can be made to bypass the remainder of the main refrigerant circuit in a bypass refrigerant circuit so as to be returned to the intake side of a compressor and to be used to cool the refrigerant flowing through the main refrigerant circuit to a subcooled state.

An air conditioner is configured by appropriating, existing refrigerant pipes, of an existing air conditioner to update indoor units and an outdoor unit of a refrigerant circuit of the existing air conditioner. The air conditioner is disposed with an updated refrigerant circuit and a mixer disposed in the updated refrigerant circuit. The updated refrigerant circuit is filled with working refrigerant and refrigerating machine oil that include an acid trapping agent that detoxifies acid components remaining in the refrigerant pipes. The mixer mixes the acid components with the acid trapping agent during refrigeration cycle operation of the updated refrigerant circuit

A method for providing 3D animation via a network in a client/server computer system. A 3D model is accessed on the client. The client then receives a series of transform updates for the 3D model via a network. The series of transform updates described for the client the manner in which to update the 3D model to implement the animation. Each of the series of transform updates are applied by the client to the 3D model to render a corresponding series of 3D images. The series of rendered 3D images are then displayed to the user to provide a 3D animation. The transform updates are streamed from the server to the client via the network. Streaming the transform updates across the network is more bandwidth efficient than streaming images. Interactivity is implemented by receiving user commands from the client via the network. In response to the user commands, the server appropriately alters the series of transform updates streamed to the user, thereby providing interactivity to the 3D animation.
