Project Overview
Project Name: Ross Empire Goods Distribution Center Heating Project
Heating Area: 40,000 square meters
Initial Heating Method: Central heating by the city's large network
Reconstruction Purpose: Improve heating quality and reduce operating costs
Project Requirements
Category Area | Indoor Temperature in Winter | Heating Time | Heating Load
Shopping Center | 40,000m² | 15 ~ 18 ℃ | 8h/day | 1800kw
Project Overview
The project is located in Heilongjiang Province, which has a continental monsoon climate with an average winter temperature of -20°C. The heating period lasts from mid-October to mid-April, requiring heating for half the year. The project, the Ross Empire Goods Distribution Center, primarily deals with goods imported from Russia; the plaza has a construction area of 40,000 square meters. Initially, the plaza used the city's large network for central heating, and heating costs became the highest operating cost of the plaza. At the same time, the city heating system had the following issues:
(1) Unstable water supply temperature, causing significant fluctuations in indoor temperature;
(2) Users cannot adjust the temperature according to their preferences;
(3) The city’s long piping network resulted in high heat loss and high costs;
(4) Inadequate water supply pressure and quantity for users at remote locations.
Design
The project uses a high-efficiency water source heat pump unit, designed with two screw compressors and a double circuit system to ensure safe heating. The unit can adjust the output water temperature as needed, ranging from 40°C to 55°C. To optimize the water source and minimize water waste, the unit uses flooded evaporator equipment with an output water temperature designed at 3.5℃, maximizing the use of groundwater and improving the energy efficiency ratio of the unit.
Project Configuration
Equipment Name | Heating Capacity | Heating Power | Hot Water Supply and Return Water Temperature | Groundwater Supply Temperature
High-efficiency water source heat pump unit | 1895kw | 403kw | 45 ℃ / 40 ℃ | 9 ℃
Benefit Analysis
The customer originally used the city’s central heating system, and the commercial heating cost was 6.72 USD per square meter, with an annual heating cost of approximately 1.7 million USD, excluding initial setup fees.
Electricity consumption statistics after renovation
Water Source Heat Pump Unit | Hot Water Recirculation Pump | Groundwater Recirculation Pump | Total Power | Average Electricity Cost
403kw | 45kw | 15kw | 463kw | US $ 0.07 / kWh
Hourly Heating Fee: 463 × 0.45 = 33 USD
Heating Cost for One Season: 208 × 8 × 30 × 6 = US $ 47,619
Solution Advantages
(1) One unit with multiple functions: widely applicable; integrates three functions of cooling, heating, and hot water.
(2) Green and environmentally friendly: no need for a boiler room for heating, no need for cooling towers, and no emission of pollutants during operation.
(3) High efficiency and energy-saving: The water source heat pump unit consumes 1kW.h of electricity, and users can receive 4.3 ~ 5.2kW.h of heat or 5.4 ~ 6.2kW.h of cooling; it saves water and land, and does not consume water resources.
(4) Flexible usage: Adjust output water temperature and usage time as needed.
(5) Smart control: The equipment uses fully automatic PLC control and is equipped with remote cloud service control functionality, eliminating the need for dedicated staff to monitor the equipment room.
