Refrigeration cycle vs heat pump cycle
WebThe liquid, having been cooled through expansion, returns to the outdoor evaporator coils to resume the cycle. The quality of a heat pump is judged by how much energy is transferred by heat into the warm space ( Q h Q h) compared with how much input work (W) is required. Teacher Support. WebDec 3, 2024 · The compressor compresses the water vapor, causing it to heat up. Meanwhile, the heat pump inside your home contains refrigerant mixture inside a loop, much like the loops of your fridge. The heat exchanger helps transfer heat from the hot, compressed vapor from the ground loops to the relatively cool refrigerant mixture at room …
