制冷是一个热力学过程，包括降低或维持空间或物体的温度。该过程包括从冷源中提取热量并将其传递给热源。冷却液是用来输送能量的。

最广泛的制冷系统是制冷循环系统。该系统遵循经典的压缩周期。

压缩：压缩机将电能转化为热能，并将其传递给制冷剂液体，提高其压力和温度。
冷凝：制冷剂在冷凝器中由气态变为液态，向热源放出热量。
膨胀：液体膨胀成气体，冷却下来。
蒸发：从冷源中吸收热量并传递给制冷剂。

吸收式制冷系统也是利用制冷剂的蒸发来吸收热量，但不使用压缩机。在这个循环中，通过向制冷剂和另一种物质（通常是水）的混合物提供热量，使其吸收热量，从而实现压差。制冷剂通常是氨或溴化锂。

热电制冷系统是利用佩尔帖效应工作的。Peltier加热器是一种固态热泵，通过对立温度梯度和消耗电能，将热量从设备的一侧转移到另一侧。

涡旋制冷机由于效率低，是最不普及的制冷机。将压缩空气切向引入湍流室，在湍流中心形成冷气流，同时外层被加热。抽出的冷气，可以用来制冷。

制冷系统存在于任何传统的冷藏室或冷冻室中，或在较高温度环境中的封闭空间内需要低温的其他应用。
