An outdoor heat exchanger includes tube-outside heat transfer coefficient adjusting means configured to adjust a heat transfer coefficient αo of the outside of a heat transfer tube through which a refrigerant flows, tube-inside heat transfer coefficient adjusting means configured to adjust a heat transfer coefficient αi of the inside of the heat transfer tube through which the refrigerant flows, and heat transfer area adjusting means configured to adjust a heat transfer area A where the refrigerant exchanges heat with a heat medium. A controller controls the heat transfer coefficient αo of the outside of the heat transfer tube, the heat transfer coefficient αi of the inside thereof, and the heat transfer area A to control a heat exchange amount of the outdoor heat exchanger.

An outdoor heat exchanger includes a fan configured to adjust a heat transfer coefficient ao of the outside of a heat transfer tube through which a refrigerant flows, a bypass passage and flow rate control valve configured to adjust a heat transfer coefficient αi of the inside of the heat transfer tube through which the refrigerant flows, and an on-off valve configured to adjust a heat transfer area A where the refrigerant exchanges heat with a heat medium. A controller controls the heat transfer coefficient αo of the outside of the heat transfer tube, the heat transfer coefficient αi of the inside thereof, and the heat transfer area A to control a heat exchange amount of the outdoor heat exchanger.
摘要:
An air-conditioning apparatus includes a heat-source-unit-side heat exchanger, a plurality of use-side heat exchangers, and a relay unit provided between the heat-source-unit-side heat exchanger and the plurality of use-side heat exchangers. The relay unit is configured to switch part of the plurality of use-side heat exchangers to a cooling operation side to switch part of the plurality of use-side heat exchangers to a heating operation side, and simultaneously performs a cooling and heating simultaneous operation by switching each of the plurality of use-side heat exchangers to the cooling operation side or the heating operation side in accordance with a control instruction.

A target condensing temperature and a target evaporating temperature are changed in accordance with a load of each load side unit obtained by using load detection means, and an operating frequency of a compressor and a rotation speed of a fan are controlled such that a condensing temperature obtained by using temperature detection means coincides with the target condensing temperature and an evaporating temperature obtained by using the temperature detection means coincides with the target evaporating temperature.
摘要:
A method and system for determining an array sequence of processing operations to maximize the efficiency of steel plate processing. Between two processing operations, a first sequence constraint based on a first attribute of each processing operation and a second sequence constraint based on a second attribute of each processing operation are defined. A system selects, as a cluster, at least one of processing operations having a common attribute value of the first attribute, and arranged in a sequence satisfying the second sequence constraint. The system regards the first sequence constraint as a sequence constraint between a plurality of clusters, and arranges the plurality of clusters in a sequence maximizing the efficiency of processing.

摘要:
A consumable electrode for the production of Nb-Ti alloy is disclosed which is capable of obtaining homogeneous titanium alloy without segregation which contains substantially equal amounts of niobium and titanium. The consumable electrode consists essentially of a compact formed by compressing a uniform mixture of niobium chips and sponge titanium.
摘要:
Apparatus, program and method for receiving input and specifying a plurality of junctions on a map, specifying an editing object range, and specifying a predetermined block of a road by inputting modifying data items, in order to modify road attribute data items within a predetermined extent. Coordinates of a starting point and a terminal point on a map are input. Additionally, coordinates of relay points can be input. Junctions closest to the starting point and the terminal point are searched, and identified. A search for a route is performed using the junction data items, and road data items of the editing object block are specified. From the junction data items included in the editing object block, the data items of a road connected to the junction within a predetermined extent are specified, and, at the same time, made to be an editing object. Modification data is received, and road attribute data items of the road that is the modifying object are updated based on the modification data.
