Modular Air Cooled Chiller

Operating principle

Cooling mode: The compressor compresses the low-temperature and low-pressure refrigerant gas into high-temperature and high-pressure gas, which is condensed into liquid in the air-side heat exchanger. After being depressurized by the throttling device, it enters the water-side heat exchanger, absorbs heat and evaporates, lowering the water temperature to provide cold air.

Heating mode: The high-temperature and high-pressure gas discharged from the compressor exhaust port enters the evaporator through the four-way reversing valve, absorbs heat from the air and becomes low-temperature and low-pressure gas, which is then compressed by the compressor back to a high-temperature and high-pressure state, completing the heating cycle.

Structural design

Modularity: It is composed of multiple independent modules, which can be flexibly combined according to the cooling demand, making it easy to expand or reduce the system scale.

Air-cooled condenser: It usually adopts finned heat exchanger and is equipped with low-speed large-leaf axial flow fan, which has the advantages of compact structure, high heat exchange efficiency and low operating noise.

Unit advantages

1. High efficiency and energy saving

- Adopting high-efficiency compressor and optimized refrigeration cycle design, the energy efficiency ratio (COP) is high.

- Supporting variable frequency technology, the operating frequency can be dynamically adjusted according to the actual load to further improve energy efficiency.

2. Flexible configuration and expansion

- The modular design allows users to increase or decrease the number of modules according to actual needs, realizing flexible configuration and expansion.

- Suitable for various scenarios from small to large.

3. Easy installation

- The assembly and commissioning are completed before leaving the factory, and only the power supply needs to be connected on site to operate.

- Save the installation cost and space of traditional cooling towers and cooling water circulation systems.

4. Easy maintenance

- The modular design makes it easier for each module unit to operate and maintain independently.

- Equipped with an intelligent fault diagnosis system to quickly locate problems and provide solutions.

5. Strong adaptability

- Applicable to a variety of working conditions (such as high temperature conditions, low load operation), meeting the needs of different scenarios.

- The cooling and heating modes can be flexibly switched according to the needs of different seasons.

6. Low noise

- With sound insulation design and high-efficiency compressor, the operating noise is low, suitable for places with high environmental noise requirements (such as hospitals and office buildings).

Comparison with traditional units

As a highly efficient and flexible refrigeration equipment, modular air-cooled hot and cold water units have been widely used in commercial buildings, industrial production, residential buildings, etc. Its high efficiency and energy saving, flexible configuration and convenient installation make it an ideal choice for many scenarios.
