From "Green Prescriptions" to "Green Investments" : Grundfos Powers "Green Engine" in Healthcare Company

Project Background

The renovation project of Shanghai Xinya Pharmaceuticals Co., Ltd. is located at the factory site at 978 Chuansha Road, Pudong District, Shanghai, covering an area of 69,534 square meters. In recent years, the original air conditioning system has suffered from high energy consumption and outdated equipment. With the growing urgency in the healthcare industry for green and low-carbon demand, the company has decided to upgrade its existing air conditioning system.

Challenges

  • Outdated and Inefficient Original Air Conditioning System with High Operating Costs
    The air conditioning system at Xinya Pharmaceutical's plant was designed with traditional methods, where the energy consumption of the pump system accounted for over 40% of the total energy consumption of the air conditioning system. The pump system was unable to adjust its output based on actual demand, resulting in significant energy waste, which contradicts the current "Dual Carbon" goals being promoted.

  • Challenges in Remote Monitoring and Maintenance
    The effectiveness of remote maintenance was suboptimal, especially during system failures. The inability to perform timely preventive maintenance could lead to longer downtime and higher repair costs.

  • Complex Hydraulic Balance Adjustment
    In multi-pump systems, improper hydraulic balance can cause certain areas to overheat or overcool, affecting the overall performance of the air conditioning system. In traditional systems, manually adjusting hydraulic balance is not only time-consuming but also difficult to achieve the desired state.

  • Short Project Timeline
    The client imposed strict requirements on the service management capabilities for project implementation, allowing only 2 months for preparation and execution. Grundfos needed to complete the design, production, and delivery of all equipment within this tight timeframe.

Grundfos Solution

  • The prefabricated and modular design not only optimizes pump efficiency control but also significantly reduces on-site construction time.
  • The distributed pumping ensures demand-driven supply, achieving flow balance and improving operational efficiency.
  • Intelligent data collection enables remote system status monitoring and preventive maintenance, allowing for unattended operation of the equipment room.
  • Chilled water system achieves over 60% energy savings compared to the original system.
  • The overall efficiency of the equipment room has improved by more than 40%.
  • COP Value reaches above 4.5.

Efficient Air Conditioning Water Distribution System Solution Drives Energy-Saving Renovation of High-Efficiency Equipment Rooms

  • The chilled water system of the equipment room adopts a constant pressure difference control method to supply water to the terminal units, while the cooling water system utilizes temperature control. Through the DELTA prefabricated pump module solution, optimal pump efficiency control is achieved, significantly reducing the energy consumption of the pumping system.
  • For terminal air conditioning equipment, based on energy demand, different zones are equipped with MAGNA3, Grundfos intelligent circulators, which supply water on demand and achieve hydraulic balance at the terminal units, further enhancing the energy efficiency of chilled water distribution.
  • Grundfos iSOLUTIONS Suite supports smart operation and maintenance of the intelligent pump units in the air conditioning system and the MAGNA3 circulators at the terminal units. It enables remote monitoring of system status, allowing for unattended operation of the equipment room.

Implementation of Complex Projects that Ensures Project Delivery and Commissioning

By replacing traditional on-site installation with prefabricated pump module, construction quality issues are resolved. Additionally, the overall performance can be tested in the factory through parallel simulation of multiple pumps, simplifying on-site installation and shortening the construction timeline.

Grundfos' sales team, service team, and internal factory support team collaborated closely to successfully provide valuable management experience for systematic energy-saving renovation projects. This optimized end-to-end efficient collaboration and accelerated the rapid development of systematic energy-saving renovation services.

"Grundfos has taken the healthcare industry as a representative case for energy-saving renovations and smart upgrades. This breakthrough will also have a substantial impact on energy conservation and carbon reduction in advanced manufacturing, various public buildings, and residential buildings across China.
