一种双冷源气悬浮离心热泵装置A kind of double cold source air suspension centrifugal heat pump device

技术领域technical field

本发明涉及一种双冷源气悬浮离心热泵装置。The invention relates to a centrifugal heat pump device with double cold source air suspension.

背景技术Background technique

目前市场上的大型冷水热泵装置都是螺杆式和离心式的产品,螺杆式压缩机都采用油润滑转子和轴承,离心式压缩机大部分采用油润滑轴承,一小部分采用的是磁悬浮式轴承。传统含有压缩机给系统带来了很多可靠性的隐患,如压缩机卡死,电机烧毁等,并且油带入系统后导致机组的性能下降,换热器的传热系数降低。同时对于磁悬浮式压缩机因为可靠性低,同时维护成本极高。现在的大型热泵装置的实现形式分为两种:一种是采用水系统切换方式,采用水式热泵机组;另一种是采用风冷式,通过四通阀切换制冷热的方式。水式热泵由于不能氟侧切换,因此要实现制冷热必须要通过复杂的水管路系统实现。而风冷式热泵只能单独实现制冷热,在进行热回收功能时只能满足某一个功能需求。At present, the large-scale cold water heat pump devices on the market are screw and centrifugal products. Screw compressors all use oil-lubricated rotors and bearings. Most of the centrifugal compressors use oil-lubricated bearings, and a small part uses magnetic suspension bearings. . Traditionally containing compressors brought many hidden dangers to the system, such as compressor stuck, motor burnout, etc., and the performance of the unit and the heat transfer coefficient of the heat exchanger decreased after the oil was brought into the system. At the same time, the magnetic suspension compressor has low reliability and high maintenance cost. The realization form of the current large-scale heat pump device is divided into two types: one is to use the water system switching method, using a water-type heat pump unit; Since the water heat pump cannot switch the fluorine side, the cooling and heat must be realized through a complex water pipeline system. The air-cooled heat pump can only achieve cooling and heat alone, and can only meet a certain functional requirement when performing the heat recovery function.
