3500M2 Heating Area Air Source Heat Pump Central Heating Project

Project Overview

The project is a government office building with a construction area of 4,500 m2, a utilization rate of about 75%, and a heating area of 3,500 m2. The non-energy-saving building was officially put into use in 2014, and it is stable, reliable and efficient. The indoor average temperature is about 20 °C, according to each. The raw coal that is generally burned by users can save about 76 tons of raw coal, reduce about 1.3 tons of SO2, reduce about 137 tons of CO2, and reduce the discharge of ash and slag by about 23 tons.

Project Sumary:

l Jet Boost compressor, high efficient and environmental-friendly, even in -25C can work in high COP

l Fan of heat exchanger is big diameter Jagged type, which increase the air flow tangent length when air going through fans, reduce noise; When the air volume is increased, the heat exchanger is more evenly.

l Multi-throttle channel design is accurate.

Multiple energy-saving devices in a single system, precise control of refrigerant flow, enabling the unit to maximize heat/cooling capacity and maximum energy efficiency in various working environments, reducing operating costs

l The water side shell and tube heat exchanger have high efficiency and reliability.

The industry's leading refrigerant distribution technology can effectively improve the uniformity of gas-liquid two-phase fluid distribution into heat transfer tubes, improve the utilization of heat exchange tubes, and achieve efficient heat transfer.

l Large-area hydrophilic aluminum heat exchangers increase the heat production.

The four-row tube V-shaped arrangement has high heat exchange efficiency and uniform wind speed distribution.

It adopts 9.52*0.35 internal thread high-efficiency heat exchange copper tube and 3.1mm large-format hydrophilic aluminum fins with better hydrophobicity; it improves the operating efficiency during frosting and reduces the number of defrosting.

The optimized long flow path design and wide expansion of the expansion throttle ensure uniform distribution of refrigerant in low temperature environments. Ensure even frosting, complete defrosting, strong heating and efficient operation
