The main difference between hot air and cold air curtains is their working principles and application scenarios.
The hot karate, also known as the hot curtain, is a device that forms thermal air flow through heating indoor air, thereby preventing the cold air from entering the room.It usually contains heating elements, such as electric heaters or hot water tray, which is used to heat cold air.This device is mainly used for winter. A warm "air wall" can be formed at the door, reducing the inflow of cold air, maintaining indoor temperature, and avoiding the energy waste of heating.
The cold air curtain, also known as the cold curtain, is to inhale outdoor air and refrigerate to form the hot air in the airflow isolation indoors.It does not need heating elements, but to form a barrier by air flow generated by high -speed fans.This device is mainly used in summer, and a cool "air wall" can be formed at the door to reduce indoor temperature and isolate outdoor noise and dust.
In general, the main difference between hot air and cold air curtains is their working principles and application scenarios.The hot air screen is mainly used for warmth in winter, while the cold air screen is mainly used for summer cooling.They are effective air treatment equipment that can improve the comfort and energy saving effect of the indoor environment.
