背景技术
相关技术中的双缸压缩机指在曲轴的轴向上设置两个气缸，两个气缸内均能实现冷媒的吸入、压缩及排气过程，并经不同的出气通道排出壳体，实现压缩机的双压力排气。
但目前的双缸压缩机考虑加工便捷性、组装简易性等因素，双缸压缩机各缸的排量是相等，而在压缩机具有双排气压力的需求下，对应不同压比的冷凝器温度不同，进出口焓差不同，对应的流量也不同，压缩机等排量的排气实际上并不能充分利用双排气的优势，无法实现最佳的效果。
发明内容

具体实施方式
为了能够更清楚地理解本申请的上述目的、特征和优点，下面结合附图和具体实施方式对本申请进行进一步的详细描述。需要说明的是，在不冲突的情况下，本申请的实施例及实施例中的特征可以相互组合。
在下面的描述中阐述了很多具体细节以便于充分理解本申请，但是，本申请还可以采用其他不同于在此描述的其他方式来实施，因此，本申请的保护范围并不受下面公开的具体实施例的限制。
下面参照图1至图12描述根据本申请一些实施例的压缩机及制冷设备。
实施例一：
一种压缩机，如图1所示，包括壳体140，第一气缸100、第一活塞110、第二气缸120和第二活塞130。壳体140上设有互不连通的第一出气端口142和第二出气端口144；第一气缸100被加工成型有容纳腔，第一活塞110偏心设置在第一容纳腔内，第二气缸120同样被加工成型有容纳腔，第二活塞130偏心设置在第二容纳腔内，第一活塞110能够在第一容纳腔内做往复运动，使得第一活塞110通过改变第一工作腔的容积而实现吸气、压缩空气和排气过程，其中，第一工作腔属于第一容纳腔的一部分，被第一活塞110的外周面、第一滑片组件280及第一气缸100的内表面围合而成；第二活塞130能够在第二容纳腔内做往复运动，使得第二活塞130通过改变第二工作腔的容积而实现吸气、压缩空气和排气过程，其中，第二工作腔属于第二容纳腔的一部分，被第二活塞130的外周面、第二滑片组件290及第二气缸120的内表面围合而成。第一气缸100经第一出气端口142排气，第二气缸120经第二出气端口144排气。通过设置两个气缸以及两个活塞而实现了双排气功能，第一气缸100和第二气缸120均能实现对冷媒的吸入、压缩和排气过程，这种设置方式避免了相关技术中设置多台压缩机来实现双排气功能而造成的成本高的问题，本申请中的一个压 缩机就能实现相关技术中两个压缩机所能实现的功能，降低了加工成本，降低压缩机的占用空间，而且有利于提高对压缩机安装过程的便利性。
另外，本申请中进一步限定第一气缸100和第二气缸120的排气压力不同，不同的排气压力能够使得冷媒到达预定温度的时间以及所需要的能量均是不同的，能够理解的是，根据压缩机的不同使用需求，第一气缸100和第二气缸120实现不同的排气压力，从而使得对应于第一气缸100和第二气缸120的冷凝器能够高效地实现冷凝功能，避免对能源造成浪费，充分利用双缸压缩机的双排气优势，显著提升压缩机的能效。
进一步地，本实施例中限定P1<P2，0.6≤(e1×(D1-e1)×H1)÷(e2×(D2-e2)×H2)≤1.9。具体地，(e1×(D1-e1)×H1)÷(e2×(D2-e2)×H2)的取值可以为0.8，1.05，1.85。其中，P1为第一气缸100的排气压力，D1为第一气缸100的内径，e1为第一活塞110相对于第一气缸100的偏心距，H1为第一气缸100的高度，P2为第二气缸120的排气压力，D2为第二气缸120的内径，e2为第二活塞130相对于第二气缸120的偏心距，H2为第二气缸120的高度。e1×(D1-e1)×H1与e2×(D2-e2)×H2的比值大小代表第一气缸100的排量与第二气缸120的排量的比值大小。
结合图1和图12所示，本申请限定P1<P2，达到第一气缸100和第二气缸120排出压力不同的目的，通过限定第一气缸100的内径不同于第二气缸120的内径、第一活塞110相对于第一容纳腔的偏心距不同于第二活塞130相对于第二容纳腔的偏心距、第一气缸100的高度不同于第二气缸120的高度，且具体范围为0.6≤(e1×(D1-e1)×H1)÷(e2×(D2-e2)×H2)≤1.9，可在实现第一气缸100的排气压力不同于第二气缸120的排气压力的同时，实现了第一气缸100的排量不同于第二气缸120的排量，从而使得对应于第一气缸100和第二气缸120的冷凝器能够高效地实现冷凝功能，避免对能源造成浪费。
图12示出的是不同排量比下，随排量比变化而发生变化的能效变化曲线，从图12中可知，随着排量比增大，能效呈现先增大后减小的趋势，由此可见，充分利用双缸压缩机的双排气优势，能够显著提升压缩机及引用该压缩机的制冷设备的能效。
需要说明的是，本申请的第一活塞110相对于第一容纳腔的偏心距，默认为第一活塞110相对于第一容纳腔的中心线的偏心距，该中心线的延伸方向与曲轴260的轴向同向。第二活塞130相对于第二容纳腔的偏心距，默认为第二活塞130相对于第二容纳腔的中心线的偏心距，该中心线的延伸方向与曲轴260的轴向同向。第一容纳腔呈圆柱状或大致呈圆柱状，第二容纳腔呈圆柱状或大致呈圆柱状。
另外，相关技术中的双缸压缩机因其作用对象、加工便捷性、组装简易性各种因素影响，双缸压缩机各缸排气相等，而在本申请中，由于第一气缸100和第二气缸120的排气压力不同，对应不同压比的冷凝器温度不同，进出口焓差不同，对应的流量也不同，从而能够充分利用双排气的优势，实现最佳的效果。
实施例二：
结合图1、图4和图6所示，在实施例一的基础上，进一步限定压缩机还包括：第一轴承150、第二轴承160、隔板组件170、第一排气出口180、第二排气出口190、第一滑片组件280和第二滑片组件290。

隔板组件170设置于第一气缸100和第二气缸120之间，第一气缸100和第二气缸120还设置在第一轴承150和第二轴承160之间，实现了第一轴承150和隔板组件170封堵位于两者之间的第一气缸100的第一容纳腔，第二轴承160和隔板组件170封堵位于两者之间的第二气缸120的第二容纳腔。
第一滑片组件280、第一活塞110的外周面和第一气缸100的内表面围成第一工作腔，第二滑片组件290、第二活塞130的外周面和第二气缸120的内表面围成第二工作腔，第一活塞110移动能够改变第一工作腔的容积从而压缩气体，第二活塞130移动能够改变第二工作腔的容积从而压缩气体。压缩机还包括第一排气出口180和第二排气出口190，使第一排 气出口180连通第一工作腔和第一出气端口142，使第二排气出口190连通第二工作腔和第二出气端口144，实现压缩机的双压力排气功能。
进一步地，第一轴承150及隔板组件170与第一气缸100相抵接，第二轴承160及隔板组件170与第二气缸120相抵接。第一工作腔经第一排气出口180连通第一出气端口142，第二工作腔经第二排气出口190连通第二出气端口144。
进一步地，第一排气出口180设置在第一气缸100或第一轴承150或隔板组件170上；第二排气出口190设置在第二气缸120或第二轴承160或隔板组件170上；第一排气出口180经壳体140的内腔连通第一出气端口142，或第二排气出口190经壳体140的内腔连通第二出气端口144。
在一个具体的实施例中，第一排气出口180设置在第一气缸100上，使得第一工作腔内的压缩气体通过第一排气出口180排出，将第二排气出口190设置在第二气缸120上，使得第二工作腔内的压缩气体通过第二排气出口190排出，方便第一工作腔和第二工作腔的排气。
在另一个具体的实施例中，第一排气出口180和第二排气出口190还可以分别设置在第一轴承150和第二轴承160上。
如图1所示，在一个具体实施例中，在第一轴承150上设有第一排气出口180，使得第一工作腔内的压缩空气经第一轴承150上的第一排气出口180。在第二轴承160上设置第二排气出口190，使得第二工作腔内的压缩空气经过第二轴承160上的第二排气出口190，由于第一轴承150和第二轴承160位于两个气缸的两侧，相互远离，有效避免第一气缸100和第二气缸120的排气过程相互影响，实现压缩机的双压力排气功能。
如图2所示，在另一个具体实施例中，隔板组件170包括第一隔板172和第二隔板174，第一隔板172和第二隔板174围成空腔，从而可在第二隔板174上设置第二排气出口190，使得第二工作腔内的压缩空气能够通过第二排气出口190排出至隔板组件170的空腔内，再通过第二出气通道210将压缩空气排出至第二出气端口144，此时，第一轴承150上设有第一排气出口180，第一工作腔内的压缩空气能够通过第一排气出口180排至第一出气端口142，保证了第一气缸100和第二气缸120能够实现相互独 立的排气功能，实现了压缩机的双压力排气功能。
