We all know by elevator that there will be self-contained air conditioners above the elevators. So, have you ever understood the air conditioners above the elevators, how does it work, and what are the advantages and disadvantages? Let's take a look at how to choose elevator air conditioners with the Escalator Company .
First, the type of elevator air conditioner
According to the environment of returning the wind, it can be divided into a car top air conditioning system and an external unit (hoistway) air supply air conditioning system.
Car top air conditioning system: The air conditioner main unit is directly placed or suspended on the top beam of the elevator car. The air conditioner extracts the air in the car and sends it back to the car after cooling (heating), and then re-starts to adjust the car. The purpose of the internal temperature.
External unit (hoistway) air supply and air conditioning system: air conditioning unit is installed outside the elevator shaft or through the central air conditioning system of the building, the treated air is sent into the elevator shaft by the air supply duct, and then the fan at the top of the car is sent into the sedan. The box realizes the adjustment of the air temperature in the car.
Second, the advantages and disadvantages of each air conditioning system
(1) Advantages and disadvantages of the car roof air conditioning system
Advantages: mature technology, rapid cooling, saving energy consumption;
Disadvantages: Increase the weight of the elevator car, installation and maintenance is more complicated than other methods, there is condensed water phenomenon.
(2) External unit (hoistway) air supply and air conditioning system
Advantages: simple structure, convenient installation and maintenance, no condensation.
Disadvantages: increase the number of duct outlets, increase investment, and high energy consumption. The elevators may cause abnormal fluctuations in wind pressure of the central air-conditioning system under high-speed operation.
Third, the elevator air conditioning system selection:
The car top air conditioning system is the preferred air conditioning system because of its mature technology and low investment. In the market, most projects use a car-top air conditioning system. In addition, for the problem of condensed water, the current air conditioner for car topping has been treated by multiple atomization evaporation of condensed water to achieve a non-drainage target, thus solving the problem of condensed water.
Fourth, the setting of the air conditioning air outlet in the car
The arrangement of the air outlet and return air inlet in the car is mainly considered from the aspects of avoiding the generation of condensed water and avoiding the formation of small airflow in the ceiling of the car. In order to avoid the generation of condensed water, generally use wood or plastic material outlet, it will not accumulate condensation water; in order to avoid the formation of small air circulation in the car roof, affecting the cooling effect, can increase the between the air outlet and the return air inlet The plane distance is generally greater than 500mm, and the air outlet is not allowed to be placed in the inner space of the ceiling.
