A thermoelectric enhanced hybrid heat pump system is provided herein. The compressor increases the pressure of the refrigerant in the pipeline. The first heat exchanger is downstream of the compressor and changes the enthalpy of the first fluid flow by heat exchange with the refrigerant. The second heat exchanger changes the enthalpy of the second fluid flow by heat exchange with the refrigerant. A thermoelectric device is downstream of the first heat exchanger and reduces the refrigerant temperature. An expansion valve is located downstream of the thermoelectric device and the first heat exchanger, on a first side and a second side of the thermoelectric device, respectively, and expands the refrigerant and reduces the refrigerant pressure while preserving the enthalpy of the refrigerant. The at least one valve reverses refrigerant flow within the conduit without changing compressor operation. The control system controls the thermoelectric device and the at least one valve to switch the heat pump system from the heating mode to the cooling mode and from the cooling mode to the heating mode.
本文中提供了热电增强混合热泵系统。压缩机增加管路内制冷剂的压力。第一热交换器在压缩机的下游并且通过与制冷剂的热交换来改变第一流体流的焓。第二热交换器通过与制冷剂的热交换来改变第二流体流的焓。热电装置在第一热交换器的下游并且降低制冷剂温度。膨胀阀位于热电装置和第一热交换器的下游,分别位于热电装置的第一侧和第二侧上,并且使制冷剂膨胀并且降低制冷剂压力,同时保存制冷剂的焓。至少一个阀在不改变压缩机操作的情况下使管路内的制冷剂流反向。控制系统控制热电装置和至少一个阀,以将热泵系统从加热模式切换到冷却模式,以及从冷却模式切换到加热模式。
