 Product Description

Screw type ground source heat pump units, also known as water-source heat pumps, are extensively utilized in large-scale projects for central air-conditioning, central heating, and high-temperature hot water. These units incorporate top-notch screw compressors, refrigerant system control components, and computer control devices that are designed and manufactured in strict adherence to industry standards. They are capable of providing both cooling in the summer and heating in the winter, making them versatile for year-round use in industrial settings with medium and low temperature cold source demands.

1. Excellent choice:

Utilizing a renowned brand compressor such as Hanbell or Bitzer, the screw type ground source heat pump units are designed with a twin-screw unit structure. This structure ensures minimal unbalanced rotational force, resulting in exceptionally low levels of vibration and noise. Furthermore, the units offer balanced part-load operation, leading to high efficiency.

2. Optimized design:

By significantly reducing water consumption, our water source heat pump units effectively conserve valuable water resources and simultaneously lower operating costs.

3. Independent research and development:

The heat pump unit utilizes an internally threaded copper tube for the evaporator and an externally finned copper tube for the condenser. This innovative design significantly enhances both the heat transfer coefficient and heat transfer capacity.

4. Energy saving and environmental protection

The heat pump refrigeration system incorporates an electronic expansion valve as its throttling element. This electronic valve offers precise control over the refrigerant flow rate, ensuring optimal performance levels for the heat pump system.

5. Advanced Controls:

Computer control and with RS-485 interface, it can realize the centralized control of building automation.

6. Electrical Safety:

The independent power supply mode is adopted to realize power isolation and strong anti-interference.

The PLC remote monitoring system added to the screw type ground source heat pump unit is convenient for users to monitor and manage the remote unit through a computer or mobile phone.

When the units leaves the factory, the pipeline assembly and electrical control system have been completed, and a trial run has been carried out on the test bench. It can be put into use only by connecting the power supply, cooling water and chilled water on site.

7. Scope of application:

① Large-scale ground (water) source heat pump units operate in a wide temperature range of water source: 10-35°C;

② It can provide not only 7℃ or 50℃ air-conditioned hot and cold water, but also domestic hot water;

③ It can also be used as a heat source for urban central heating.

Screw type ground source heat pumps are widely used in office buildings, shopping malls, hotels, hospitals, schools, theaters, stadiums, entertainment centers, industrial and mining enterprises and other large and medium-sized buildings to provide chilled water/(domestic) hot water for central air-conditioning systems, and can also be used Provide process chilled water and hot water for textile, chemical, food, electronics, scientific research and other industries.
