HON MING Air-cooled Integrated Rooftop Air-conditioning Unit Successfully Serves Tonghua Railway Station in Jilin Province

Enterprise Introduction

Tonghua Railway Station, located in Changliu Village, Huantong Township, Dongchang District, Tonghua City, Jilin Province, is affiliated to China Railway Shenyang Bureau Group Co., Ltd. It is a comprehensive passenger transport hub integrating high-speed rail, common slow trains, long-distance passenger transport and public transportation.

The new station building has a construction area of 6 platforms and 14 lines. It is equipped with facilities such as smart ticket checking and no-contact face scanning recognition entry. The waiting room can accommodate 1,500 people, and the transportation capacity has increased by 4 times compared to the old station.

Tonghua Railway Station in Jilin Province, a key regional transportation hub in Northeast China, prioritized improving its operating environment and passenger experience. Leveraging its superior air-cooled packaged rooftop air conditioning units, HON MING successfully provided a comprehensive HVAC solution for Tonghua Railway Station, creating a comfortable, year-round waiting environment for passengers traveling north and south. As a large public building with expansive space and fluctuating passenger flow, the station required an air conditioning system with robust heat exchange capabilities, rapid response times, and stable, continuous operation. The HON MING air conditioning team undertook this important task, aiming to create a benchmark project that would stand the test of time.

Breakthrough of Project

The success of the project did not happen overnight. The HON MING team faced many severe challenges and overcame them one by one with their profound technical background.

Difficulty 1: Roof installation and spatial structure limitations

Difficulty 2: Adaptability to complex environments and centralized control

Faced with these challenges, HON MING engineers rose to the occasion. Through extensive testing, comparisons, and on-site surveys, they continuously revised the project plan. After several revisions, they ultimately selected the HON MIGN air-cooled integrated rooftop air conditioning unit for the project. This unit features a highly integrated design, integrating all systems

and is installed directly on the station roof, occupying no available indoor space. During the installation process, the HON MING engineering team conducted precise load calculations and structural assessments, customizing a professional mounting base and windproof fixing solution. The solution seamlessly integrated the unit with the building's roof waterproofing, ensuring a safe, stable, and long-term reliable installation. Thanks to the highly efficient unit, the system's overall operating energy efficiency ratio has been significantly improved, saving the station considerable operating costs and achieving a win-win situation in both economic and social benefits.

The success of the HON MING Air Conditioning Tonghua Railway Station project is more than just a simple application of a product; it demonstrates the technological strength of Made in China in specialized air conditioning. We empower architecture with technology and warm journeys with craftsmanship. In the future, HON MING will continue to uphold the philosophy of "keep improving and pursuing excellence" to provide the highest-quality HVAC solutions for even more challenging environments.

Rooftop air-cooled air conditioning (heat pump) unit

HON MING rooftop air-cooled air-conditioning (heat pump) unit is a large and medium-sized air-conditioning equipment that integrates cooling, heating, air purification and other functions. The compressor, evaporator, condenser and throttling components in the air-conditioning system are assembled in a box. It is an integral structure. Because it is mostly installed on the roof, it is called a "rooftop air conditioner" (referred to as rooftop unit).

Rooftop air-cooled (heat pump) air conditioning units have the characteristics of high efficiency and energy saving, low installation cost, easy use, stable performance and low maintenance cost. They are widely used in various rail transportation and industrial plants.

Features

Safe and reliable:

The unit is rainproof, heat-insulated, and well-sealed, ensuring electrical safety. Power wiring is housed within the electrical control box, eliminating the risk of roof leaks. The unit is equipped with protections for high voltage, low voltage, overload, phase error, phase failure, and overheating, ensuring safe and reliable operation.

Compact structure:

The unit has a reasonable layout and is composed of an evaporation air supply section and a compression condensation section. The unique structural design allows the refrigeration system and the ventilation system to be perfectly combined.

Easy maintenance:

The internal structure of the unit is highly integrated, and operation and maintenance are simple during operation. Faults are easy to troubleshoot, and parts can be easily replaced within the existing space.

Efficient and quiet:

The unit uses direct evaporative cooling, eliminating the need for secondary heat exchange. This system boasts high efficiency and timely and accurate control to match the unit's energy consumption with the room's load, ensuring optimal operation and significantly reducing operating costs. The unit is located outdoors, requiring only indoor ducting, resulting in low noise levels and minimal floor space.

Excellent dehumidification:

The unit adopts direct evaporative cooling with a lower dew point dehumidification function, which is especially suitable for use in low temperature and high humidity environments, so that indoor humidity control can be more stable, such as rainy and high humidity seasons.
