Project Overview

案例概述

Solareast Heat Pump Zero-Carbon Laboratory Building (2023–present), with a total floor area of 32,000 m² across four stories, is strictly designed around the core concept of a "Zero-carbon Building." As the centerpiece of the zero-carbon park, it serves as a key platform for clean power generation, cooling, and heating, as well as a critical node for load regulation and energy optimization.

日出东方热泵零碳实验楼（2023年至今）总建筑面积32000平方米，共4层，严格遵循“零碳建筑”核心理念。作为零碳园区的核心，它是清洁发电、供冷供热的关键载体，也是负荷调节与能源优化的重要节点。

The southern and western facades are equipped with customized black monocrystalline silicon heterojunction (HJT) photovoltaic modules that integrate power generation with architectural aesthetics. The rooftop distributed PV system has a total capacity of 765 kWp, generating approximately 1.07 million kWh annually—enough to meet the building’s daily electricity demand. An 800 kW / 1,720 kWh lithium battery energy storage system is also installed to enhance self-consumption of solar power and deeply integrate photovoltaic, storage, and building functions.

建筑南、西立面采用定制化黑色单晶硅异质结（HJT）光伏组件，兼具发电与装饰功能；屋顶分布式光伏总容量达765kWp，年发电约107万kWh，满足日常用电需求。配套800kW/1720kWh锂电池储能系统，提升光伏自发自用率，实现光-储-建深度融合。

For heating and cooling, the building uses a 1,082 kW high-efficiency magnetically levitated ground-source heat pump (with a seasonal COP of 6.6) supported by 168×120-meter-deep ground heat exchangers, along with seven 181 kW variable-frequency air-source heat pumps. A 1,000 m³ stratified thermal storage tank (with a cooling capacity of 7.3 MWh) is intelligently controlled to optimize energy charging/discharging strategies, increase photovoltaic consumption, improve system efficiency, and significantly reduce operational costs.

冷热供应采用1082kW高效磁悬浮地源热泵（COP达6.6）及168口120米深地埋管换热井，并辅以7台181kW变频空气源热泵。1000m³分层蓄能钢罐（蓄冷量7.3MWh）通过智能算法优化储热/冷策略，提升光伏消纳与系统能效，显著降低用能成本。

Project Implementation

项目实施

1. Design Concept: To achieve the "zero-carbon" goal, the project strictly follows the core concept of "zero-carbon building" in design. While the building envelope meets thermal insulation performance requirements, it fully taps into the potential of renewable energy around the building. The clean power supply consists of curtain wall BIPV + rooftop PV + energy storage system, and the clean cooling and heating supply consists of air-source heat pump + ground-source heat pump + stratified thermal storage steel tank.

设计理念：为实现“零碳”目标，项目在设计上严格遵循“零碳建筑”核心理念，建筑本体围护结构满足保温、隔热性能的同时，充分挖掘建筑周边可再生能源应用潜力，清洁电力能源供给由幕墙BIPV+屋顶光伏+储能系统组成，清洁冷热供给由空气源热泵+地源热泵+分层蓄能钢罐组成。

2. Envelope Optimization: Cooperated with Lianyungang Architectural Design Institute, adopted leading domestic building insulation technologies and materials to reduce building air conditioning load.

围护结构优化：与连云港建筑设计院合作，引用国内领先的建筑保温技术和材料，降低建筑空调负荷。

3. PV Curtain Wall Innovation: Innovatively adopted crystalline silicon modules instead of traditional thin-film modules, achieving higher power generation efficiency.

光伏幕墙创新：创新性引用晶硅组件而非传统薄膜组件，发电效率更高。

4. Energy-Saving Technology Selection: Selected ground-source heat pump + air-source heat pump + cold and heat storage steel tank. Cooperated with China Academy of Building Research to model and simulate hourly temperature, humidity, radiation and other parameters in Lianyungang area for 8760 hours a year, combined with heat load simulation software, to optimize the building envelope and reduce building cooling and heating load.

节能技术选用：选用地源热泵+空气源热泵+储冷储热钢罐。与中国建筑科学研究院合作，针对连云港地区全年8760个小时逐时的温度、湿度、辐照等参数，结合热负荷仿真软件建模仿真，优化建筑围护结构，降低建筑冷热负荷。

5. Challenge Overcoming: Heating and cooling energy consumption accounts for about 60% of building energy consumption. To reduce carbon emissions from cooling and heating energy consumption, the building innovatively adopts the industry's most energy-efficient magnetic levitation heat pump + ground-source heat pump + cold and heat storage steel tank. This system not only has an operating energy consumption about 30% lower than conventional air conditioning systems, but also the heat storage steel tank can shift daytime load to night, making full use of valley electricity for heat storage and greatly reducing operating costs.

挑战克服：供冷供热在建筑运行过程中的能耗是建筑能耗的主要组成部分，约占建筑能耗的60%左右。为降低冷热能耗带来的碳排放，本建筑创新性采用行业内能效最高的磁悬浮热泵+地源热泵+储冷储热钢罐。该系统不仅运行能耗比常规空调系统低30%左右，同时储热钢罐可将白天的负荷转移至夜晚，充分利用谷电蓄热，大幅降低运行费用。

6. Before-and-After Comparison: Before the project, traditional buildings relied on fossil energy and conventional air conditioning systems, with high energy consumption and carbon emissions, and poor energy utilization efficiency. After the implementation of the project, the building achieves zero-carbon operation through clean energy supply and intelligent energy management, with significantly reduced energy consumption and carbon emissions, and greatly improved energy utilization efficiency, setting an example for the zero-carbon transformation of similar buildings.

实施前后对比：项目实施前，传统建筑依赖化石能源和常规空调系统，能耗高、碳排放量大，能源利用率低；项目实施后，通过清洁能源供给与智能能源管理，建筑实现零碳运行，能耗和碳排放量显著降低，能源利用率大幅提升，为同类建筑的零碳转型树立了典范。
