  • Patent number: 11965701
    Abstract: In a heat exchanger, an outer diameter of a plurality of heat transfer pipes is defined as Do, a wall thickness is defined as tP, an area represented by a numerical expression of a row pitch L1×a step pitch L2 is defined as A, and an area represented by a numerical expression of ((Do?2×tP)/2)2×? is defined as B, a relation of Do<5.5 mm, a relation of (0.2076×tP2?0.1480×tP+0.0545)×Do{circumflex over (?)}(?0.0021×tP2?0.0528×tP+0.0164)?B/A?(0.0219×tP2?0.0185×tP+0.0043)×ln (Do)+(1.6950×tP2+1.8455×tP+1.5416), and a relation of B/A<0.0076×tP2?0.0417×tP+0.0574 are satisfied.

  • Publication number: 20240118040
    Abstract: A heat exchanger includes: a first heat exchanger configured to transfer heat between air and refrigerant; and a second heat exchanger provided in series with the first heat exchanger in a first direction that is a flow direction of the air, and configured to transfer heat between the air and the refrigerant. The first heat exchanger includes first heat transfer tubes through which the refrigerant flows, which are spaced apart from each other in a second direction intersecting the first direction, and each of which has a tube axis extending in a third direction intersecting the first and second directions. The second heat exchanger includes: second heat transfer tubes though which the refrigerant flows, which are spaced apart from each other in the second direction, and each of which has a tube axis extending in the third direction; and a corrugated fin provided between the second heat transfer tubes.

  • Publication number: 20230105361
    Abstract: A combination weighing device includes: a storage unit that stores time-series measurement values sequentially acquired by the measurement hoppers; a time measurement unit that measures an elapsed time from a timing corresponding to supply of the products to the measurement hoppers until a timing at which the time-series measurement values enter a region considered to be stabilized when the time-series measurement values stored in the storage unit converge to the region considered to be stabilized as a stabilization time until the measurement values become stabilized; and a selection unit that acquires the stabilization times by the time measurement unit over a plurality of cycles and can select a recommended stabilization time that is the stabilization time in which a predetermined measurement accuracy can be maintained based on a standard deviation of the acquired stabilization times for the plurality of cycles.

  • Publication number: 20230101971
    Abstract: A management system (1) manages a production line (2) including a processing apparatus (20) and an inspection apparatus (40). The management system (1) includes: a control unit (61) that estimates a processing time at which a defective food is processed by the processing apparatus (20) based on a time at which the defective food determined as a defective product by inspection by the inspection apparatus (40) is inspected; and a storage unit (62) that stores processing information of the processing apparatus (20) related to the processing time estimated by the control unit (61) such that the processing information can be output.
