空压机热回收与溴化锂联合制冷制热系统
技术领域
本发明涉及制冷制热设备，具体地说是一种空压机热回收与溴化锂联合制冷制热系统。
背景技术
压缩机运行时产生的余热，可引起电机高温及排气高温，不仅影响压缩机的使用寿命，而且影响压缩空气的质量。传统的方法是采用风冷或水冷，将这部分热量散发到大气环境，不仅造成热量的浪费，而且对环境造成了热污染。另一方面，溴化锂制冷机组工作的动力可通过燃烧油、煤、气提供，也可由蒸汽、热水提供，这些都需要消耗能源。如能将这两者有机的结合起来，将达到节能减排及减缓全球气候变暖速度的目的。
发明内容
针对上述问题，申请人经过研究改进，提供一种空压机热回收与溴化锂联合制冷制热系统。
本发明的技术方案如下：
一种空压机热回收与溴化锂联合制冷制热系统，包括顺序连接的空压机热回收装置、热回收水箱和保温水箱，所述空压机热回收装置与热回收水箱之间、热回收水箱与保温水箱之间均通过双向对流管路联通，所述保温水箱的出水口通过管路分别连接溴化锂制冷机组、风机盘管和组合式空调机的供水口，所述溴化锂制冷机组的出水口也通过管路分别连接风机盘管和组合式空调机的供水口，所述风机盘管和组合式空调机的出水口通过管路连接热回收水箱的回水口，同时通过管路连接溴化锂制冷机组的回水口。
其进一步的技术方案为：还包括太阳能热水器，所述太阳能热水器与热回收水箱之间通过双向对流管路联通。
以及，其进一步的技术方案为：还包括燃气锅炉和热交换器，所述燃气锅炉与热交换器之间通过双向对流管路联通，所述热交换器与热回收水箱之间通过双向对流管路联通。
本发明的有益技术效果是：
本发明采用空压机热能回收装置，一方面可回收空压机运行产生的废热，另一方面也避免了热量的损失。同时，将热回收提供的热能用来驱动溴化锂制冷机组，一方面可达到节能减排的目的，另一方面为企业节约了开支，为社会解决了电荒这一大难题。
本发明的优点将在下面具体实施方式部分的描述中给出，部分将从下面的描述中变得明显，或通过本发明的实践了解到。
附图说明
图1是本发明的总体结构框图。
具体实施方式
下面结合附图对本发明的具体实施方式做进一步说明。
如图1所示，本发明由空压机热回收装置1、热回收水箱2、保温水箱3、溴化锂制冷机组4、风机盘管5、组合式空调机6、太阳能热水器7、燃气锅炉8、热交换器9、连接上述单元的管路以及安装在管路上的水泵组成。
空压机热回收装置1、热回收水箱2和保温水箱3顺序连接。空压机热回收装置1与热回收水箱2之间、热回收水箱2与保温水箱3之间均通过双向对流管路联通。可选配太阳能热水器7，太阳能热水器7与热回收水箱2之间通过双向对流管路联通。可选配燃气锅炉8和热交换器9，燃气锅炉8与热交换器9之间通过双向对流管路联通，热交换器9与热回收水箱2之间通过双向对流管路联通。
保温水箱3的出水口通过管路分别连接溴化锂制冷机组4、风机盘管5和组合式空调机6的供水口，溴化锂制冷机组4的出水口也通过管路分别连接风机盘管5和组合式空调机6的供水口。风机盘管5和组合式空调机6的出水口通过管路连接热回收水箱2的回水口，同时通过管路连接溴化锂制冷机组4的回水口。
本发明的工作方式如下：
(1)热回收水箱
热回收水箱2中的水主要依靠空压机热回收装置1加热，当空压机热回收装置1回收的热量不能使热回收水箱2的温度达到要求时，可通过太阳能热水器7来辅助加热，或者开启燃气锅炉8通过热交换器9将热量传递给热回收水箱2。
(2)保温水箱
当热回收水箱2达到设计温度(70～100℃)后，水泵启动，热水由热回收水箱2送到保温水箱3内，当保温水箱3内达到设定的高水位时，水泵关闭，然后检测热回收水箱2的水位，补水至水满。当保温水箱3用水后，水位低于设定水位后，水泵启动进行补水。
另外，当保温水箱3由于箱体散热，使保温水箱3与热回收水箱2之间水的温差大于5℃时，通过水泵、阀门的动作，使水在保温水箱3与热回收水箱2之间循环加热，使保温水箱3维持设定温度。
制热时：保温水箱3的水进入风机盘管5或组合式空调机6，将热量传给室内空气，使室温提高，降温后的回水返回热回收水箱2继续加热。
制冷时：保温水箱3的热水进入溴化锂制冷机组4的发生器，使溴化锂制冷机组4工作，制得的冷媒水进入风机盘管5或组合式空调机6，将冷量传给室内空气，使室温降低，冷媒水回水返回溴化锂制冷机组4。
以上所述的仅是本发明的优选实施方式，本发明不限于以上实施例。可以理解，本领域技术人员在不脱离本发明的基本构思的前提下直接导出或联想到的其他改进和变化，均应认为包含在本发明的保护范围之内。
