日本Nry／k司研制的热交换Z，具有可变导热系数的特性，称为“热控墙”．热技培主要靠一个双态温差环境系统工作，利用室内外冷热空气的温差将热量从室内传递到室外．双态温度环流系统由两个热交换器和一个连接它们的环形制冷管及低温气化制冷剂组成。因此，热控墙具有利用室外 Japan Nry / k Division developed heat exchange Z, with a variable thermal conductivity characteristics, known as the “thermal wall.” Thermal technology mainly rely on a dual-mode temperature and temperature environment system work, the use of indoor and outdoor temperature difference between hot and cold air will pass the heat from the room to the outdoors. The bimodal temperature circulation system consists of two heat exchangers and a ring-shaped refrigeration pipe and a cryogenic gasification refrigerant connecting them. Therefore, the thermal wall has the use of outdoor
