Acheng District Xiaoling Nursing Home 200+300KW Electromagnetic Boiler Heating Project
Project Overview
Located at Xiaoling Nursing Home in Acheng District, Harbin City, this project is a clean heating renovation initiative designed for elderly care facilities. The project adopts a 200KW + 300KW dual-unit parallel configuration combined with intelligent linkage control technology to provide winter heating and year-round domestic hot water for the nursing home. The system operates silently, stably, and with zero emissions, fully meeting the high standards of elderly care institutions for safety, comfort, and uninterrupted heating.
Key Parameters
- Project Location: Xiaoling Nursing Home, Acheng District, Harbin City
- Installed Capacity: 200KW + 300KW dual-unit parallel
- Equipment Type: Electromagnetic boiler (dual-unit linked control)
- Application Scenario: Nursing facility heating + domestic hot water
- Heating Season: 2025-2026
Customer Pain Points
Elderly care institutions are extremely sensitive to the stability, safety, and quietness of heating systems. The original coal-fired and small gas-fired boilers had the following shortcomings:
- Heating output was affected by coal quality and furnace conditions, causing large nighttime temperature fluctuations and making elderly residents susceptible to cold;
- Combustion noise and dust impacted the living environment;
- Aging equipment resulted in high maintenance frequency, posing gas and carbon monoxide safety hazards;
- Operation required dedicated on-site personnel, increasing the logistical management burden on the nursing home.
Solution
Jingyu Thermal Energy tailored a 200KW + 300KW dual-unit linked control solution for Xiaoling Nursing Home. The units are installed side by side in a dedicated equipment room and operate in coordination through a PLC intelligent control cabinet. The system automatically adjusts start/stop and power output based on outdoor temperature and actual load, enabling full-power operation during extreme cold weather and efficient low-load operation during early and late cold periods.
Unit Configuration
- Core Units: One 200KW and one 300KW electromagnetic boiler, each with thermal efficiency ≥98%;
- Linked Control Logic: Master-slave alternation + load following, ensuring overall heating supply is unaffected by single-unit failure;
- Terminal Forms: Hybrid system combining underfloor heating, radiators, and fan coil units, with flexible zone-based control;
- Hot Water Supply: Independent year-round domestic hot water circuit, prioritizing the use of off-peak residual heat.
Core Technology and Highlights
- Water-Electricity Separation Design: Completely eliminates the combustion and leakage risks of traditional boilers, meeting the safety requirements of elderly care scenarios;
- Dual-Unit Linked Control Technology: Intelligently adjusts output power based on load, balancing energy savings and comfort;
- Cloud IoT Monitoring: Temperature, pressure, and flow data uploaded to the cloud in real time, supporting remote inspection and alarms;
- Ultra-Silent Operation: No combustion and no high-frequency mechanical vibration, ensuring a quiet and comfortable living environment for elderly residents.
Implementation and Timeline
The project was completed from site entry to commissioning in a single phase. The equipment room layout fully considered maintenance space and pipeline routing. The control cabinet integrates a touchscreen interface, allowing operations staff to independently perform daily switching and fault reset after brief training.
Operating Results
- Indoor temperature remained stable within a comfortable range throughout the entire heating season, significantly improving the living experience for elderly residents;
- No visible smoke or combustion odors, enhancing the overall environmental quality of the nursing home;
- The cloud platform supports 7×24-hour remote monitoring, substantially reducing operations and maintenance manpower;
- Dual-unit alternating operation extends equipment lifespan, resulting in more favorable life-cycle costs.
Customer Value
This project establishes a green, comfortable, and safe clean energy renovation benchmark for elderly care institutions in Acheng District, demonstrating significant value in promoting the low-carbon upgrade of regional elderly care infrastructure.
