- Successful Application Examples
Hotel Occupancy Rate Changes in Thailand
The occupancy rate of a certain hotel in Thailand shows significant fluctuations throughout the day and between peak and off-peak seasons, with large variations in cooling load. Chillerone provided an 80-ton inverter chiller, which automatically adjusts the compressor speed according to actual demand, avoiding frequent start-stop of fixed-speed units at low loads. After the customer compared inverter chillers with non-inverter ones, they believed that the variable-frequency solution was more suitable for occupancy rate changes. After the equipment was put into use, during periods of low occupancy, it no longer operated at full speed, ensuring stable cooling.
Daily Load Curve of an Office Building in Singapore
The cooling load of a certain office building in Singapore is concentrated from 6:00 to 22:00, and drops significantly at night. Chillerone provides a 120-ton inverter scroll chiller, which continuously adjusts the output according to the building’s load curve and remains highly efficient even under partial load conditions. When the client was evaluating the price of inverter chillers, they included the operating electricity cost in the full life cycle comparison. After the system was put into use, the cooling supply during the day and at night automatically matched, making the management more convenient.
Production Start and Stop at a Rubber Factory in Pakistan
A number of production lines at a rubber factory in Pakistan were started and stopped according to the plan. The cooling load fluctuated rapidly between 25 and 60 tons. Chillerone provided a 60-ton inverter chiller. The compressor speed was adjusted according to the production rhythm to avoid frequent start-stop operation of traditional fixed-frequency units. When the customer was making inquiries, they focused on the inverter chiller price in Pakistan. Eventually, they chose the variable frequency solution. After the equipment was put into use, it operated more stably at partial loads, and the cooling output was closer to the process requirements.
Cleanroom of a Canadian Pharmaceutical Factory
The cleanroom of a certain pharmaceutical factory in Canada needs to maintain stable temperature and humidity throughout the year. The cooling load varies with the outdoor temperature and the number of people in the room. Chillerone provided a 90-ton inverter chiller to supply chilled water to the facility’s HVAC system. The compressor speed adjusts according to cooling demand, helping maintain the required chilled-water supply temperature during varying loads. Room temperature and humidity are managed through the integrated air-handling and humidity-control systems. The variable-speed configuration was selected to support more efficient operation during partial-load periods.

What Is An Inverter Chiller?
ChillerOne inverter chiller is a refrigeration device that uses a frequency converter to intelligently adjust the speed of the compressor. It is different from traditional fixed-frequency machines that only have two states: on and off. Instead, it can automatically adjust the cooling output power according to your actual cooling load requirements.
This cooling method based on your needs not only achieves precise temperature control but also effectively avoids energy waste, which ultimately helps you achieve significant energy conservation and consumption reduction as well as more stable and reliable operation.
Working Principles of Inverter Chillers
The core working principle of an inverter chiller is to change the frequency of the power supply to the compressor in real time through a frequency converter, thereby precisely controlling the speed of the compressor and the cooling output power.
- Step 1: The temperature sensor continuously monitors the return water temperature of the chilled water.
- Step 2: The intelligent controller compares the return water temperature with the user-set temperature to calculate the cooling capacity requirement.
- Step 3: If the return water temperature is higher than the set value, it indicates insufficient cooling capacity. The controller will instruct the frequency converter to increase the output frequency to drive the compressor to accelerate operation and enhance the cooling capacity. If the return water temperature approaches or equals the set value, it indicates that the supply and demand of cooling capacity are balanced. The controller will instruct the frequency converter to reduce the frequency, allowing the compressor to run at a low speed and only maintaining the necessary cooling capacity.
- Step 4: When the cooling load is extremely low, the compressor can maintain an extremely low rotational speed far below the rated power, saving you energy.
Features and Advantages of Inverter Chillers
Intelligent Variable Frequency Drive
Our inverter chiller is equipped with a frequency converter, which can steplessly adjust the motor speed of the compressor by changing the power supply frequency. This enables the refrigeration output of our unit to be adjusted within a wide range, achieving a precise match between the refrigeration capacity and the actual cooling load from the outside.
Significant Energy Conservation
As our compressors mostly operate at medium and low speeds that match actual demands, this avoids energy waste caused by frequent starts and stops. Therefore, they have extremely high energy efficiency under partial load conditions, and their overall operating energy consumption is usually 20% to 40% lower than that of fixed-frequency units, significantly reducing your operating costs.
Strong Stability
By fine-tuning the compressor speed in real time, our inverter chiller is able to control the outlet or return water temperature of chilled water within an extremely precise range. This excellent stability is crucial for ensuring the quality of your precision manufacturing or high-end process.
Long Service Life
When our inverter chiller starts and stops, the smooth acceleration and deceleration processes are achieved through the frequency converter, which reduces the electrical and physical shock to the motor and mechanical transmission components. In addition, smooth continuous operation avoids the fatal wear and tear on the compressor caused by frequent starts and stops. These features significantly reduce the failure rate and extend the service life of your entire machine system.
Low Noise
When the load demand is low, both our compressors and fans operate at a lower rotational speed, and the mechanical noise and airflow noise they generate are significantly reduced. This makes our inverter chiller more suitable for places that require a quiet environment.
Strong Adaptability
Thanks to the application of frequency converters, our inverter chillers can operate stably within a wide range from as low as 30% of the rated load to as high as over 100%. The compressor can be maintained at a low speed for a long time, which avoids the limitation of traditional chillers that must be shut down when demand is low, and greatly expands its applicable working condition range.
The specific energy-saving effect varies depending on the operating duration and load rate. According to the data results, the average energy-saving rate is between 20% and 40%. We can help you analyze energy consumption and calculate the expected energy savings based on your specific working conditions.
Our inverter chillers adopt advanced frequency converters and intelligent control systems. At partial load, the compressor will reduce its rotational speed to match your cooling capacity requirements, and at this time, the energy efficiency ratio is actually higher. Meanwhile, smooth and low-speed operation avoids the impact caused by frequent starts and stops, making it more stable and reliable compared to fixed-frequency units.
Absolutely fine. Even in the cold winter, our inverter chiller can smoothly reduce the frequency to regulate the cooling output, ensuring the stable operation of the compressor under low load and low ambient temperature.
Our frequency converter itself incurs approximately 2% to 4% power loss, but this part of the loss is very small compared to the energy saved by the compressor due to frequency conversion regulation. The net energy-saving benefits brought by frequency conversion technology are very significant.
To deal with extremely rare emergencies, our control system has been designed with a complete emergency response mechanism. Some of our models support automatic switching to fixed-frequency mode operation, ensuring that the cooling system will not be interrupted and meeting the process requirements of your project that cannot be shut down. Meanwhile, we have a stock of commonly used frequency converters in stock, which can quickly respond to your needs and replace them.
