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 no on-site combustion 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.
