Air curtain principle of selection: a hot air curtain air curtain design parameters of the supply air temperature. Generally determined by calculation. For the production of a wide public buildings and houses outside the door, the air curtain air temperature is less than 50 ℃; for the tall outer door, air temperature is less than 70 ℃. Outlet air curtain wind. Generally determined by calculation. For residential and commercial buildings, and its outlet velocity can be 4 ~ 9m / s; for industrial buildings, outlet velocity can be 8 ~ 24m / s, not more than 2Sm / s. 2. Non-heated air curtain (isothermal air curtain) Scope ① civil air-conditioning system and door entrance foyer in the trunk. ② require higher operating counter commercial buildings. ③ some sporadic Park fog, different ignorant, odor room door. ④ distribute gas and dust in the opening process equipment. 3. When the hot air curtain range applicable ① heating outdoor design temperature is equal to or lower than the region -20 ℃, when the shop door opened frequently the main channel, bucket or front room door is not set, and the class time more than 40min. ② regardless of the level of heating outdoor design temperature and the length of time the door opened, when production requirements are not allowed to reduce the indoor temperature, but can not be set before the door bucket or room. ③ heating outdoor design temperature is higher than the 200e area heated air curtain, when reasonable technical and economic indicators. ④ large number of scattered wet room or near the outer door, there is a fixed job for civil and industrial construction entrance foyer and doors in the trunk. Air Curtain Applications: air curtain installed in refrigeration, air conditioning, dust, insulation of shopping malls, theaters, hotels, restaurants, conference rooms, cold storage, and other home theater and the air above the door curtain, start the machine vertical Air curtains, indoor and outdoor air can apart, played only accessible, but also to prevent the exchange of indoor and outdoor hot and cold air at the same time, with dust, pollution prevention, anti-mosquito effect. Widely used in electronics, instrumentation, pharmaceutical, food, precision machining, chemical, footwear, and services, business, etc. industries. Air Curtain Features: The air curtain air curtain air stream generated speed parameter, divided into two separate indoor and outdoor temperature zones create a comfortable indoor environment, keep indoor air-conditioning and air purification effect, while saving energy and making the air circulation effectively isolate dust, fumes, odors and insects and other microorganisms. Prevent cold (warm) air outflow, saving electricity continuously formed air door, can effectively prevent the cold (warm) air leakage, saving electricity, the interior is divided into two separate temperature zones, long-term operation of the air conditioner, the assisted circulation adjust the temperature, to achieve energy savings to improve the environment. When the effect of air circulation in the gym, cinema, entertainment, etc. due to the large space conditioning energy produced uneven distribution of the air circulation system features air curtain to reach room temperature equilibrium.
