From Rooftop to Radiators: Smart Heating for 60,000 m² 2025-11-25

Project Overview

Project Name: Community Central Heating Project
Building Area: 60,000 m²
Heating Method: Air Source Heat Pump
This project focuses on providing sustainable and efficient heating for a large residential community by adopting advanced dual-system low ambient air source heat pump units.
Project Requirements & Design
To ensure reliable heating performance in cold climates, the project utilizes screw-type low ambient air source heat pump units. Each unit is equipped with two screw compressors, operating in a dual-system dual-circuit design to enhance safety and redundancy.

Type	Building Area	Winter Indoor Temperature	Heating Load	Terminal Type
Residential Community	60,000 m²	18 ~ 22℃	3000KW	Floor Heating

The system allows outlet water temperature adjustment between 30℃ and 55℃, providing flexibility according to seasonal heating demands. With its split structure design, the compressor and condenser are installed indoors, while the air-cooled fins are placed on the rooftop, reducing outdoor noise and optimizing building integration.
System Configuration
• Dual-System Heat Pump Units with screw compressors
• Split Design: indoor compressors & condensers, rooftop air-cooled fins
• PLC Intelligent Control with remote cloud-based monitoring
• EC Fans ensuring energy savings and low noise

Equipment Name	Heating Capacity	Heating Power	Hot Water Supply and Return Temperature	Quantity
Screw-Type Low Ambient Air Source Heat Pump	1000KW	356 kW	45℃/40℃	3 sets

Advantages of the Project

1. Eco-Friendly: No boiler room required; zero on-site emissions.
2. High Efficiency: Consumes 1 kWh of electricity to deliver 2.5–3.5 kWh of heat.
3. Flexible Operation: Adjustable water temperature and operation time to suit user demand.
4. Smart Control: Fully automated PLC with cloud monitoring—no dedicated operator needed.
5. Low Noise & Low Energy Fans: EC fans provide quieter, more efficient operation.
6. Split Design Benefits:
o Reduced rooftop load
o Indoor compressor placement minimizes outdoor noise
o Key components indoors extend system lifespan
