摘要: A refrigeration apparatus is provided in which compression efficiency can be improved and the heating of water for a hot water supply can be made more efficient. The refrigeration apparatus is a water heater (1) for treating water in a water circuit (910) having a water inlet tube (901) for leading water supplied from the exterior to a water branching point (W), heat source water tubes (902, 903) and intermediate water tubes (904, 905) extending from the water branching point (W), and a water outlet tube (906) leading to the exterior from a convergent point (Z) where the heat source water tubes (902, 903) and the intermediate water tubes (904, 905) converge; wherein an intercooler (7) performs heat exchange between refrigerant passing through an intermediate refrigerant tube (22) leading from a low-stage side to a high-stage side, and water flowing through the intermediate water tubes (904, 905). A heat source-side heat exchanger (4) subjects refrigerant passing through a connecting tube (72) for connecting a discharge side of a high-stage compression element (2d) and an expansion mechanism (5) to heat exchange with water flowing through the heat source water tubes (902, 903) without subjecting the refrigerant to heat exchange with water flowing through the water inlet tube (901).

摘要: The present invention relates to compressors including a compression mechanism whose volume can be changed by partially ejecting, through a bypass passage, refrigerant in a compression chamber.
The area of an opening of the bypass passage formed in a compression chamber is sufficiently ensured.
A compressor (20) includes a low-stage side compression mechanism (40a) having a low-stage side cylinder (41a) and a low-stage side piston (47a) and configured to compress refrigerant in the low-stage side cylinder (42a). The low-stage side compression mechanism (40a) is provided with a bypass passage (66) whose upstream end is opened to a low-stage side cylinder chamber (42a) and through which refrigerant is partially ejected from the low-stage side cylinder chamber (42a) so as to be returned to a suction side of the low-stage side compression mechanism (40a). The cross section of the upstream end of the bypass passage (66) is elongated circumferentially about a rotational axis (X).摘要翻译: 本发明涉及包括压缩机构的压缩机,该压缩机构的体积可通过旁通通道部分地喷射压缩室中的制冷剂而改变。 充分确保形成于压缩室的旁通通路的开口面积。 压缩机20具备低级侧压缩机构40a,该低级侧压缩机构40a具有低级侧缸体41a和低级侧活塞47a,并构成为对低级侧缸体42a内的制冷剂进行压缩 )。 低级侧压缩机构40a设置有上游端向低级侧汽缸室42a开口并且从低级侧汽缸室42a部分地喷出制冷剂的旁路通路66, (42a)以便返回到低级侧压缩机构(40a)的吸入侧。 旁路通路66的上游端的横截面围绕旋转轴线X周向延伸。

摘要: There is the problem that, since the operation condition of an air-conditioning apparatus is determined based on an existing database, a target space cannot be brought sufficiently close to a desired environment state. The air-conditioning control system (1) performs air-conditioning of a target space using an air-conditioning apparatus (10). The air-conditioning control system (1) includes a generation unit (34), a prediction unit (33), an evaluation unit (35), an extraction unit (36), and an air-conditioning controller (19). The generation unit (34) generates a plurality of candidates for an air-conditioning setting value of the air-conditioning apparatus (10). The prediction unit (33) predicts an environment state using an NN model (41). The NN model (41) predicts the environment state of the target space based on the air-conditioning setting value. The evaluation unit (35) evaluates the environment state corresponding to the air-conditioning setting value. The extraction unit (36) extracts an air-conditioning setting value having the highest evaluation by the evaluation unit (35) from among the plurality of candidates for the air-conditioning setting value. The air-conditioning controller (19) controls the air-conditioning apparatus (10) with the air-conditioning setting value extracted by the extraction unit (36).

摘要: In order to increase the evaporation capacity of a use-side heat exchanger regardless of operating conditions, a suction injection pipe (61) and a subcooling heat exchanger (62) are provided at a main refrigerant circuit (20) in which a main refrigerant circulates. Further, a sub-refrigerant circuit (80) that differs from the main refrigerant circuit (20) and in which a sub-refrigerant circulates is provided. A control unit (9) performs control for switching between a cooling action of the subcooling heat-exchanger that cools the main refrigerant that is sent to a main use-side heat exchanger (72a, 72b) by using the suction injection pipe (61) and the subcooling heat exchanger (62), and a cooling action of the sub-refrigerant-circuit that cools the main refrigerant that is sent to the main use-side heat exchanger (72a, 72b) by using the sub-refrigerant circuit 80.

摘要: In two compression units (41, 51) of a compressor, phases of respective pistons (45, 55) are configured to be opposite to each other. The piston (45, 55) has a non-circular outer peripheral surface, whereas a cylinder chamber (60, 70) has an inner peripheral surface of which shape is determined based on an envelope of the outer peripheral surface of the piston (45, 55) in rotation. The compressor includes an introduction section (67, 68, 163a, 164a) configured to introduce an intermediate-pressure refrigerant into a compression chamber (75) of the compression unit (41, 51).
