Installation and category introduction of elevator air conditioner

Lead: At present, many commercial elevators are equipped with elevator air conditioners, mainly to make it convenient for people not to feel uncomfortable because of boredom in the elevator, and to improve people's comfort when taking the elevator. What about the installation of elevator air conditioning?

Elevator air conditioning installation is complex and diverse. Many technicians lack working experience and professional knowledge, and have no certain understanding and cognition of the installation procedures of elevator air conditioners, which easily leads to many accidents in their work. Let the professional technicians of Tuba Rabbit popularize the installation and types of elevator air conditioners for everyone.

1. What is elevator air conditioning?

The elevator air conditioner is installed on the car, and it must be solved that there can be no condensed water when the air conditioner works. Therefore, the elevator air conditioner generally adopts the method of secondary evaporation to re-evaporate the condensed water to keep the installation environment dry. In addition, some air-conditioned cars don't have enough power and need to pull the accompanying cables.

Second, the elevator air conditioning installation

The elevator air conditioner is directly placed or hung for measurement. The installation method can occupy the elevator car roof space to the maximum extent and minimize the influence of the air conditioner weight on the elevator. At the same time, the stress cushion is used in the installation, which greatly reduces the influence of elevator vibration on air conditioning.

? 3. What kinds of elevator air conditioners are there? ?

According to the different return air environment, it can be divided into automobile overhead air conditioning system and external unit (shaft) air conditioning system.

1, car roof air-conditioning system: the air-conditioning main unit is directly placed or hung on the cross beam of the elevator car roof, and the air in the car is pumped out by the air conditioner, cooled (heated) and sent back to the car repeatedly, so as to adjust the air temperature in the car.

Advantages: mature technology, rapid refrigeration and energy saving;

Disadvantages: the weight of elevator car increases, the installation and maintenance are more complicated than other methods, and there is condensed water.

2. Air supply and air conditioning system for external machine (hoistway): The air conditioning unit is arranged outside the elevator hoistway or through the central air conditioning system of the building, and the treated air is sent into the elevator hoistway through the air supply pipeline, and then sent into the car by the fan at the top of the car, so as to adjust the air temperature in the car.

Advantages: simple structure, convenient installation and maintenance, and no condensation.

Disadvantages: increasing the number of air duct tuyeres, increasing investment, high energy consumption, and easy to cause abnormal fluctuation of wind pressure in central air conditioning system under high-speed operation of elevators.

produce

Hot summer: During the operation of the elevator car, the temperature inside the car will rise and even reach the state of "steamer" due to external thermal radiation or natural heat dissipation of passengers. The conventional solution is to install a fan in the elevator, but the temperature of the car is often too high;

Winter in the north: When the overall heating is not ideal, the temperature of the elevator car is too low, and passengers feel uncomfortable. In order to improve the comfort of elevator ride, elevator air conditioning came into being.

contrast

Elevator air conditioning is different from conventional air conditioning.

The elevator air conditioner is installed on the car, and it must be solved that there can be no condensed water when the air conditioner works. Therefore, the elevator air conditioner generally adopts the method of secondary evaporation to re-evaporate the condensed water to keep the installation environment dry. In addition, some air-conditioned cars don't have enough power and need to pull the accompanying cables.

function

The more advanced elevator function on the market can realize the setting of switching time, operation mode and constant temperature. In addition, elevator air conditioners have developed into single cooling type, cold and warm type, negative ion disinfection type and other models, and can be customized according to different elevator types.

use

Air conditioning is widely used in various passenger elevators, medical elevators and sightseeing elevators.

This air conditioner is uniquely designed according to the requirements of modern society for human health. It exhausts air from the elevator shaft and delivers fresh air to the car in the form of fresh air. It is especially suitable for high-end hotels, institutions, hospitals, office buildings and other important public places, and can effectively avoid and prevent the air with pathogenic bacteria exhaled by passengers from polluting the elevator or attaching to the dust filter net after being inhaled by air conditioners.

Through the above matters needing attention in elevator air conditioning installation, I hope to help technicians in their work. Due to the different specifications and models of elevator air conditioners, the prices are also different. In terms of price, it is divided into middle and high grades, generally between 3000- 1 10,000 yuan. People are choosing elevator air conditioners, which can be customized according to different elevator types.
