    • PROBLEM TO BE SOLVED: To provide a binary refrigeration cycle apparatus capable of shortening a defrosting period, and having high efficiency of operation.SOLUTION: A refrigeration cycle apparatus includes a low temperature-side refrigeration cycle 110, a high temperature-side refrigeration cycle 120, and detects frost-formed state of a low temperature-side evaporator 114 of the low temperature-side refrigeration cycle 110. When an operation should be shifted to a defrosting operation for thawing frost of the low temperature-side evaporator 114, an operation of the low temperature-side compressor 111 of the low temperature-side refrigeration cycle 110 is continued, an operation of the high temperature-side compressor 121 of the high temperature-side refrigeration cycle 120 is only stopped, and the operation is shifted to the defrosting operation. When the operation is shifted to the defrosting operation, heat-accumulated high temperature low temperature-side refrigerant is supplied to the low temperature-side evaporator 114 to defrost. Accordingly, it is possible to shorten the defrosting time and to enhance the efficiency of operation of a refrigeration cycle.
    • 解决问题:提供能够缩短除霜期间并且具有高效率的二元制冷循环装置。 解决方案:一种制冷循环装置,包括低温侧制冷循环110,高温侧制冷循环120,并且检测低温侧制冷循环的低温侧蒸发器114的结霜状态 当将低温侧蒸发器114的霜冻的操作切换到解冻操作时,低温侧制冷循环110的低温侧压缩机111的运转继续进行, 高温侧制冷循环120的高温侧压缩机121仅停止,操作转移到除霜运转。 当操作转换到除霜操作时,将蓄热的高温低温侧制冷剂供给到低温侧蒸发器114以进行除霜。 因此,能够缩短除霜时间,提高制冷循环的运转效率。 版权所有(C)2013,JPO&INPIT

    • PROBLEM TO BE SOLVED: To promote the stabilization of an operation restoration temperature at a cancellation time of defrosting in a thermostat having a defrosting push button or the like that controls the inside temperature of a storage room of a refrigerator or the like.
      SOLUTION: On the end face on a differential lever 37, because a round hole 37d is formed which is larger than a differential pin stem 38 but smaller than a differential pin stepped part 38a, and there is a clearance between the differential pin 38 stem and the differential lever 37, the frictional force of a penetrating hole 32 that penetrates the differential pin 38 and a cam 33 is made difficult to be added to the differential lever 37 engaged with the differential pin 38, so that a stable defrosting restoration temperature can be obtained in which temperature variations are reduced. Furthermore, after inserting the differential pin 38 through the differential lever round hole 37d, a cap 38d is mounted on the differential pin lower end 38c, or the differential pin lower end 38c is molded to form a constitution having a larger diameter than that of the round hole 37d of the differential lever 33, so that the differential pin can be incorporated easily without using a special kind of a jig or the like, and that an inexpensive thermostat can be supplied in which the numbers of assembling man-hours is reduced.

    • 要解决的问题:为了促进在具有控制冰箱等的储藏室的内部温度的除霜按钮等的恒温器的除霜的取消时间的操作恢复温度的稳定化。 解决方案:在差速器杆37的端面上,由于形成圆孔37d,其大于差动销杆38但小于差动销脚阶部38a,并且差动销 38杆和差速器杆37,穿过差动销38和凸轮33的穿透孔32的摩擦力难以被添加到与差动销38接合的差动杆37上,使得稳定的除霜恢复 可以获得温度变化降低的温度。 此外,在通过差动杆圆孔37d插入差速销38之后,在差动销下端38c上安装盖38d,或者将差动销下端38c模制成具有比直径大的构件 差速器杆33的圆孔37d,使得差分销可以容易地结合,而不使用特殊的夹具等,并且可以提供廉价的恒温器,其中组装工时的数量减少。 版权所有(C)2006,JPO&NCIPI
