Passenger elevator (passenger elevator) is an important means of transportation in modern buildings. The design of facilities in the car is directly related to the passenger's riding experience and comfort. A well-designed car should not only have basic safety performance, but also provide a series of humanized facilities to maximize passenger comfort.

1. Lighting and ventilation facilities
Lighting and ventilation facilities play a vital role in the passenger elevator car. They not only affect the comfort of passengers, but are also directly related to the use effect and overall image of the elevator. The lighting design in the car needs to be both bright and soft to ensure that passengers can have a comfortable and clear visual experience when entering the car at any time. Common lighting facilities include ceiling lights and wall lights, which usually use high-efficiency and energy-saving light sources such as LEDs to ensure brightness and reduce energy consumption. In addition, the layout of lighting facilities must also be reasonable to avoid glare or shadows and ensure that passengers can receive uniform lighting in every corner of the car. Ventilation is equally important. As a relatively closed space, the car can easily produce odor and discomfort if the ventilation is poor. Therefore, ventilation fans or exhaust vents are usually installed in the car to ensure air circulation. These ventilation facilities can effectively remove the dirty air in the car and introduce fresh air to keep the air in the car fresh. At the same time, the design of ventilation facilities must also take into account noise and energy consumption issues to ensure that while providing good ventilation effects, it will not cause interference to passengers or increase additional energy consumption.

2. Safety facilities
The safety facilities in the passenger elevator car are the prerequisite for ensuring passenger comfort. The emergency call button is one of the most common safety facilities in the car. Passengers can use this button to contact the outside world and seek help in case of emergency. In addition, emergency lighting is installed in the car to ensure that in the event of a power outage or other emergency, there is still enough lighting in the car for passengers to use. The car is also equipped with safety handrails to provide passengers with additional support and stability, especially when the elevator starts, stops or encounters an emergency.

3. Control and display facilities
The control panel is the main interface for passengers to interact with the elevator. The control panel of modern elevators usually adopts a touch or button design, with a simple and clear interface and easy operation. There are not only floor selection buttons on the panel, but also auxiliary function buttons such as opening the door, closing the door, and emergency stop. Display facilities include floor displays and operating status indicators. The floor display can display the elevator's current floor and the upcoming floor in real time, helping passengers understand the elevator's operating status. The running status indicator light indicates the current status of the elevator through different colors or flashing patterns, such as normal operation, stop, fault, etc.

4. Comfort facilities
In order to improve the comfort of passengers, modern elevator cars are often equipped with comfort facilities such as music playback systems, air conditioning or temperature adjustment devices, and interior decoration. The music playback system can play soft background music to create a relaxing and pleasant riding environment for passengers. The air conditioner or temperature adjustment device can automatically adjust according to the temperature in the car, ensuring that passengers can enjoy a comfortable temperature in all seasons. In terms of interior decoration, the car is usually made of non-slip, wear-resistant and easy-to-clean materials, which not only ensures the safety of passengers but also facilitates cleaning. At the same time, the color matching and decoration style in the car will also be carefully designed according to the overall style and usage scenarios of the building to create a harmonious and beautiful visual effect.

The design of facilities in the passenger elevator car covers many aspects such as lighting, ventilation, safety, control and display, and comfort. The rational configuration and optimized design of these facilities can not only improve passenger comfort, but also improve the efficiency and safety of elevators. With the continuous development of technology, the facilities in the elevator car will continue to be upgraded and improved in the future, bringing passengers a more convenient and comfortable riding experience.
