The differences between elevator air conditioners and household air conditioners

     Overall, the working principles of elevator-specific air conditioners and household air conditioners are basically similar, but there are indeed some differences between the two, as follows:

     In terms of positioning: Household air conditioners are designed for family residences, usually used in bedrooms and living rooms, with a relatively large usable space. Elevator air conditioners, on the other hand, are specifically designed for elevator cars and are applicable to much smaller Spaces.

     2. In terms of the structure of the external system: Household air conditioners are usually one-to-one, meaning one outdoor unit corresponds to one indoor unit, such as split units and floor-standing units, etc. However, the elevator air conditioner has only one main unit (i.e., an integrated air conditioner), and all components are installed in one main unit.

     3. In terms of capacity: Household air conditioners usually come in various specifications and models of different sizes, such as small 1-horsepower, 1-horsepower, 1.5-horsepower, 2-horsepower, 2.5-horsepower, 3-horsepower and above, which can be used from small rooms to large living rooms. However, elevator air conditioners are generally only available in small-sized models such as 1 horsepower, 1 horsepower, and 1.5 horsepower, with limited usable space.

4. In terms of installation: In addition to installing the indoor unit of a household air conditioner, it is also necessary to drill holes in the wall to lay pipes for the installation of the outdoor unit. This will damage the overall structure of the house and affect the aesthetic appeal of the architectural decoration. The elevator air conditioner is installed on the car and requires a dedicated cable for use. Generally, it is connected to the air inlet and outlet and the panel, and the installation is relatively simple.

     5. In terms of functions and features: Household air conditioners are relatively expensive, but they have a large cooling capacity and air supply volume, low noise, and are available in both fixed-speed and inverter types. There are also many energy-saving and low-carbon function designs that can be freely chosen, making them suitable for both large and small rooms. Elevator air conditioners are relatively inexpensive, but they have smaller cooling capacity and air supply volume, produce more noise, usually only have constant speed, and have few functions, making them suitable for smaller Spaces.

     6. From the perspective of environmental protection technology: The air volume circulation of household air conditioners is only for the indoor air circulation, and very few use the function of exchanging fresh air. The elevator air conditioner, while lowering the indoor air temperature, also ensures the exchange of fresh air with the air inside the car by drawing in fresh air from outside, thus preventing users from suffering from "air conditioning illness". This design of the fresh air exchange duct will prevent the indoor temperature from dropping too low.

     7. In terms of warranty and usage time: Household air conditioners are generally guaranteed for 5 years. They are usually only used for 3 to 4 months in summer each year, with 5 to 8 hours of use every day. They can be used for about 5 to 10 years. Some with proper maintenance can be used for up to 15 years. Elevator air conditioners are generally guaranteed for one year. However, due to their poor usage environment and the high temperature outside the elevator car, especially in sightseeing elevators where the temperature can reach over 60 degrees Celsius, the temperature difference is too large. Moreover, they are used 24 hours a day throughout the year. Such usage environment and frequency will greatly affect the service life of elevator air conditioners. Generally, they can be used for about 2 to 3 years. If the daily maintenance is appropriate and the usage environment is slightly better, it can still be used for 3 to 5 years.
