Rooftop Package Unit, 18kW-360kW

Rooftop packaged units are large-scale air conditioning equipment that integrate cooling, heating, and air purification. The design of rooftop packaged units is relatively simple, usually including one or more compressors, each responsible for an independent refrigeration circuit.

These separate systems can operate independently, allowing selective activation of certain systems when the air conditioning load is not high, to achieve effective energy control and reduce operating costs. Typically, rooftop packaged units encapsulate all necessary components, including compressors, condensers, evaporators, throttling components, gas-liquid separators, fans, and electrical control boxes, in a sealed box. During installation, only the ductwork needs to be connected to the box.

Due to its compact design, wide range of cooling capacity, flexible adjustability, quick installation process, and economical operating costs, rooftop air conditioning units have been widely used in the field of air conditioning. Especially in areas with scarce water resources, unsuitable for installing cooling towers, requiring air-cooled condensers, and difficult to maintain, such as the Americas and the Middle East, this equipment is very popular. It is widely used in various places such as supermarkets, banks, hotels, office buildings, factories, hospitals, and airport terminals.

Rooftop package units have the following features:

1. Multi-functionality: It adopts an integrated design, integrating cooling, heating, air supply, air purification, electrical control and other functions to provide comprehensive climate control.

2. Intelligent control: Equipped with standard RS485 communication interfaces and ModBus protocol, it can be connected to building automation control systems for intelligent control, reducing air conditioning operating costs.

3. High-efficiency compressors: Use high-efficiency scroll compressors from well-known brands, characterized by low noise and long life.

4. Eco-friendly design: Use R410A refrigerant, which is environmentally friendly.

5. Quiet and comfortable: The unit is placed outdoors, only ductwork is needed indoors, making the indoor environment quieter and more comfortable.

6. Cost-saving: No need for machine rooms and supporting equipment such as pumps, cooling towers, etc., saving space and initial investment.

7. Operational safety: Equipped with multiple protection functions, such as high pressure, low pressure, overload, short circuit, etc., to ensure safe operation.

8. Easy maintenance: Easy to inspect and maintain, convenient for regular inspection and maintenance.

9. Flexible air supply and return methods: Depending on the installation environment, different air supply and return methods can be chosen, such as bottom supply and return, side supply and return, top supply and return, etc.

10. Auxiliary heating: For systems with high heating demand in winter, electric auxiliary heating can be added to increase heating capacity.

11. Energy-saving and air quality improvement: Adjust the amount of fresh air based on the enthalpy difference between indoors and outdoors, achieving energy saving and improving indoor air quality during the transitional season.

12. Durability: The unit has a neat appearance, flexible structure, and is made of anti-corrosion materials and high-quality parts, with a long service life suitable for various climatic conditions.

13. High reliability: Factory pre-assembly, leak testing, vacuuming, and internal wiring, each unit is fully tested before delivery to ensure immediate use.

14. Precise throttling: Use electronic expansion valves for throttling, precisely controlling the superheat of refrigerant in the evaporator to maintain high cooling output.

15. Strong environmental adaptability: Rooftop packaged units are suitable for water-scarce areas because they do not require cooling towers or cooling water systems.

16. Comprehensive product range: The new generation of rooftop packaged units offers a variety of base models to meet the cooling and air processing needs in different scenarios.

These advantages make rooftop packaged units widely used in commercial and industrial buildings.
