Waste heat source heat pump unit Feature and Application：
Powerful Compression
The screw compressor provides efficient and powerful compression, enabling the unit to handle large heat loads. This makes it suitable for applications that require high heating or cooling capacities, such as commercial buildings or industrial processes. For example, in a large office building, the screw heat pump can quickly and effectively heat or cool the entire space.
Efficient Heat Exchange
The unit is equipped with high-performance heat exchangers that maximize heat transfer. This allows for efficient extraction and utilization of heat from the source, whether it’s air, water, or ground. The advanced design of the heat exchangers ensures optimal performance even in challenging conditions. For instance, in cold climates, the heat exchangers can still extract heat from the air effectively.
Intelligent Control
The screw heat pump unit features an intelligent control system that monitors and adjusts operation in real-time. It can automatically optimize performance based on factors such as outdoor temperature, indoor demand, and energy costs. This not only ensures comfortable indoor conditions but also maximizes energy savings. For example, the control system can adjust the compressor speed and heat exchanger flow rates to match the changing heating or cooling needs.
Durable Construction:
The unit is built with high-quality materials and components to ensure durability and long service life. The screw compressor is designed to withstand heavy use and harsh operating conditions. The housing and other parts are made of corrosion-resistant materials to withstand exposure to the elements.

For instance, in industrial settings where the unit may be exposed to dust, moisture, and temperature fluctuations, the durable construction ensures reliable performance
Application:
Industrial Processes:
Screw heat pump units can be used to provide heat for processes such as drying, distillation, and heating of liquids. They can extract heat from waste heat sources in the industry and reuse it, improving energy efficiency. For example, in a food – processing factory, the unit can be used to heat water for cleaning or to provide heat for drying food products.
Swimming Pool Heating
They are excellent for heating swimming pools. The high – efficiency heat transfer of the screw heat pump unit allows for quick and cost – effective heating of pool water. This enables pool owners to extend the swimming season, even in cooler climates. For a public swimming pool, the unit can maintain a comfortable water temperature, making it accessible to users for a longer period of the year.
District Heating and Cooling:
Captures waste heat from power plants, factories, or data centres to provide centralized heating or cooling for urban areas. Waste heat source heat pump unitreduces the need for traditional energy sources.
Wastewater Treatment Plants:
Extracts low-grade heat from sewage and wastewater for use in municipal or industrial heating, significantly improving energy efficiency and reducing operational costs.
Residential Heating and Cooling

Waste heat source heat pump unit Details
Working Principle:
screw heat pump unit is based on the refrigeration cycle, where heat is absorbed from one source and transferred to another. The process starts with the screw compressor compressing refrigerant gas, raising its temperature and pressure. The high-temperature gas then flows to the condenser, where it releases heat to a medium (like water or air) and condenses into a liquid. The liquid refrigerant passes through an expansion valve, where its pressure drops, allowing it to evaporate in the evaporator as it absorbs heat from the surrounding environment. The cycle repeats, transferring heat from a low-temperature source to a high-temperature medium, providing efficient heating or cooling. The basic steps include:
Condensation:
The high-pressure, high-temperature refrigerant gas enters the condenser, where it releases heat to the surrounding medium (e.g., water or air) and condenses into a liquid.
Compression:
The refrigerant is compressed in the compressor, raising its temperature and pressure.
Evaporation::
The low-pressure liquid refrigerant absorbs heat from the environment in the evaporator, evaporating back into a gas, and the cycle repeats.
Expansion and Recycling:
The liquid refrigerant passes through the expansion valve, where its pressure drops, allowing it to cool down and prepare for the evaporation process
Efficiency and Performance:
The efficiency of screw heat pumps is measured by the Coefficient of Performance (COP), typically ranging from 3 to 5, meaning they produce 3 to 5 times the energy they consume. They operate efficiently under partial loads and are more efficient with water or ground sources than air, especially in colder climates.
In terms of performance, screw heat pumps work well across a wide temperature range, are highly reliable for continuous use, and can deliver significant heat output, making them ideal for industrial and commercial applications.
Frequently asked questions
Screw heat pumps use a rotary screw compressor, which is more robust and efficient than the compressors in smaller systems like piston or scroll compressors. They are best suited for large-scale industrial or commercial applications due to their high capacity and efficiency under varying load conditions.
With proper maintenance, screw heat pumps typically last 15 to 20 years or more. Their heavy-duty components, especially the screw compressor, are designed for long-term reliability and durability.
The efficiency is measured by the Coefficient of Performance (COP), which compares the amount of heat energy provided to the amount of electrical energy used. The higher the COP, the more efficient the system. COP values typically range from 3 to 5.
Yes, screw heat pumps are reversible and can provide both heating and cooling by reversing the direction of the refrigerant flow, making them versatile for year-round climate control.
Regular maintenance includes cleaning filters, checking refrigerant levels, inspecting the heat exchanger, and servicing the compressor. Scheduled maintenance helps ensure efficiency and prolongs the unit’s lifespan.
Screw heat pumps are generally designed for large commercial or industrial applications due to their size, capacity, and higher initial cost. For residential use, smaller systems like air-source or ground-source heat pumps are typically more appropriate.
