Product Description
JIANGSU SUJING GROUP CO.,LTD
Customizable Simultaneous Cooling and Heating High-Temperature Screw Heat Pump Unit
As one of China's earliest professional manufacturers of purification air conditioners and HVAC equipment, Sujing specializes in R&D, production, sales, and installation. We operate two core segments: air conditioning systems and heat pump systems. The heat pump line includes CO2 heat pumps, cascade variable frequency units, air source (chilled water) units, water-cooled chillers, industrial screw units, air-cooled modules, and drying units.
Our products are widely applied in industry, agriculture, commerce, transportation, and aerospace, as well as in specialized fields like green heating, coal mines, oil fields, livestock farming, agricultural drying, and biomedicine. They are exported to over 30 countries, including the U.S., Finland, the Netherlands, Canada, and Brazil.
145ºC Simultaneous Cooling and Heating High-Temp Cascade Screw Heat Pump
updated in 2025-09-02
Product Introduction
Sujing Simultaneous Cooling and Heating High-Temperature Screw Heat Pump Unit is a high-efficiency integrated heat pump unit capable of both cooling and heating simultaneously. It adopts refrigerant multi-stage compression cascade technology and intelligent control technology. While producing high-temperature hot water to meet process heating needs, it recovers heat from medium-low temperature water to generate low-temperature chilled water, thereby fulfilling the cooling requirements for process production or air conditioning temperature reduction. The unit has no redundant cooling or heat discharge, achieving extremely high comprehensive energy utilization efficiency.

The unit has no redundant cooling or heat discharge, achieving extremely high comprehensive energy utilization efficiency.
- Combined Cooling & Heating, Dual Effects in One Unit: Can simultaneously provide low-temperature chilled water and high-temperature hot water/steam, realizing two-way energy saving.
- Eco-Friendly Refrigeration for a Green Future: Adopts new-generation environmentally friendly refrigerants such as R515B/R245fa/R1233zd(E) with ODP (Ozone Depletion Potential) = 0.
- High-Temperature Breakthrough for Industrial Applications: Delivers high-temperature hot water up to 145ºC, breaking the temperature limit of conventional heat pumps and covering a wide temperature range.
- Screw Technology for Reliability & Durability: Equipped with screw compressors that resist high pressure and high temperature, offering large heating capacity per unit and enabling 24/7 continuous operation throughout the year.
- Significant Economy & Fast Investment Return: The application of combined cooling and heating effectively reduces the overall energy consumption of the unit, with a comprehensive energy saving rate of over 40% and reduced carbon emissions.
