When we walk into the elevator, we always think of a problem, that is, the elevator is a fairly closed space. How does it keep the air flowing? I think most people have never thought about it, nor understand it. Most air conditioners work similarly. Of course, it is easy to see that some elevators have exhaust fans, but that is only a small part. The main route for elevator ventilation is air conditioning. Don't think that only indoor rooms can be installed with air conditioners. In fact, the elevators also have matching air conditioners to ensure the air circulation inside the elevators. Here is a brief introduction to the functions of the elevator air conditioner and what is the use of elevator air conditioners! So that you don't know nothing when you use it later.
Elevator air conditioning principle
Elevator-specific air conditioners can not directly discharge condensate into the elevator shaft, plus some restrictions such as installation space, so the structure and layout of elevator air conditioners have their own characteristics. At present, elevator air conditioners mostly use strong body machines. In fact, its working principle is similar to that of household air conditioners, which are composed of refrigeration compressors, condensers, capillary tubes and evaporators, and auxiliary equipment. The refrigeration method used is also steam compression refrigeration. The compressor can compress the low-pressure refrigerant vapor into high-temperature and high-pressure steam, and then send it to the fin-and-tube condenser for cooling, while the outdoor-side axial fan continuously forces air to flow through the condenser and puts the air in the condenser. The heat is taken away. After the high-pressure steam is condensed into a high-pressure liquid by the condenser, it will be depressurized by capillary throttling. After the anti-pressure treatment, it will enter the fin-and-tube evaporator to vaporize. It is known that the vaporization heat absorption and vaporization of the physical action After that, it can flow through the evaporator under the action of the centrifugal fan, and the air can be cooled. The cold air is blown into the room by the centrifugal fan, so as to achieve the purpose of cooling the indoor air under the action of continuous circulation.
Elevator air conditioning is different from conventional air conditioning
The elevator air conditioner is installed on the car. It must be solved when there is no condensed water in the air conditioner work. Therefore, the elevator air conditioner generally uses the secondary evaporation method to re-evaporate the condensed water to keep the installation environment dry. In addition, there is not enough power supply on some of the air-conditioned cars, and it is necessary to pull the accompanying cable.
What are the functions of elevator air conditioning?
1. It can be ventilated, dedusted and dehumidified to purify the air and avoid infection.
2, can also heat, and has an environmentally friendly refrigerant, sterilization and other optional features.
3, installation and maintenance is more convenient, can be selected according to different types of elevators, can fully meet the different needs of users.
4, can effectively eliminate the blind zone of central air-conditioning, to achieve the same level as other indoor air-conditioning, improve its building grade.
5, can achieve cooling in the summer, the effect of heating in the winter, bring people a comfortable environment.
What is the use of elevator air conditioning?
Air conditioning brand: cold and warm TCL air conditioning
TCL titanium elevator air conditioner uses anti-corrosion materials, which are light in weight and small in size. The condensed water is subjected to multiple gasification treatments without overflowing. The TCI air conditioner has low noise and provides a quiet and comfortable environment when used. While the elevator is running normally, TCL's independent power supply design ensures that the elevator air conditioner has no effect on the elevator operation. In addition, the installation of TCL is relatively simple and convenient, and the operation is strong. If there is abnormal operating condition, please check with the professional in time. It is recommended to clean the filter regularly, once in the last month.
Air conditioning brand: Yueli elevator air conditioner
Specialized waterless treatment design with outstanding features such as strong cooling, low noise and low power consumption. The elevator has strong overall stability and high energy efficiency ratio. It is also an independent power supply design, does not interfere with the elevator system and lighting system, and also has a power-off protection function. Installation and operation is simple, cleaning and maintenance are also very convenient, and will not affect the maintenance and maintenance of the elevator. In addition, the unique arc-shaped tuyere design can make full use of the original air outlet of the car top to achieve the rapid change of air. It is used in large hotels in Guangzhou, Shenzhen, Zhongshan, Dongguan and other places, and the evaluation is good.
Air conditioning brand: small snowman elevator air conditioning
The design, production, installation and after-sales of the small snowman elevator air conditioner are very good guarantees. In the use of elevator air conditioners, the most important thing is to require no overflow, low noise, safety and reliability. "Small Snowman Air Conditioning" is the earliest elevator-specific air conditioner that appears on the market. The design and manufacture are carried out in accordance with industrial-grade standards. Compared with the general household air-conditioning retrofits, the quality is still guaranteed.
In addition, there are many elevator air conditioner brands on the market: Mitsubishi, Schindler, Otis, Hitachi, Toshiba, Fuji, Thyssen, KONE, etc. Nowadays, the air-conditioning elevator air conditioner is generally used, which is suitable for both winter and summer. Many domestic brand elevator air conditioner manufacturers are constantly improving in terms of quality and after-sales, and consumers can choose more and more brands.
