How a Heat Pump Works

A home-tech infographic explaining how a heat pump heats and cools a house, drawn as a looping refrigerant cycle between an outdoor and indoor unit. Labeled stages - evaporator, compressor, condenser, expansion valve - carry colored arrows (blue for cold, red for warm) around the loop, with a summer/winter toggle showing reversed flow. Clean flat illustration, a cool-and-warm split palette of teal and coral on off-white. Bold rounded title 'How a Heat Pump Works' at the top, numbered steps, a small efficiency (COP) badge.

一张家居科技信息图,讲解热泵如何为房屋供暖与制冷,画成室外机与室内机之间循环的制冷剂回路。带标注的各阶段——蒸发器、压缩机、冷凝器、膨胀阀——用彩色箭头(蓝为冷,红为热)绕回路流动,并有一个夏季/冬季切换显示流向反转。干净的扁平插画,冷暖分色配色,青与珊瑚色,米白底。顶部粗体圆角标题「热泵的工作原理」,编号步骤,一个小的能效(COP)标签。
