Our company specializes in researching and producing screw type high-temperature water source heat pump units with a maximum temperature of 100 ℃ and a heating capacity of 50kw to 3000kw. The screw type high-temperature water source heat pump unit uses environmentally friendly refrigerant R134a or specialized high-temperature mixed refrigerant, fully utilizing industrial wastewater, bathing wastewater, geothermal tail water, oilfield reinjection water, urban centralized heating return water, etc. as heat source water. It can completely replace coal-fired gas boilers, achieve high efficiency and energy saving, and produce high-temperature hot water above 75 ℃ to meet the needs of centralized high-temperature heating or industrial process hot water. Compared to room temperature screw water source heat pump units, HLSG screw high-temperature water source heat pump units have higher hot water temperatures and a wider range of applications. They are suitable for heating occasions with radiators at the end, slaughterhouses, chemical electroplating and electronics, metallurgical smelting, food drying, food tobacco drying, textile printing and dyeing, packaging printing, cosmetics raw materials industry, electronics and other industries that have high-temperature heat sources and require high-temperature hot water.

The main features of our screw type high-temperature water source heat pump unit are as follows:

1、 The overall framework structure is compact and beautiful:

1. The layout of the unit structure is convenient, compact, and simple. The compressor, evaporator, and condenser are arranged in layers above and below, while other refrigeration components are arranged along the periphery of the frame, making it convenient for users to fully grasp the operating status of the unit. This provides effective protection for the evaporator and condenser during transportation, machine room installation, and daily operation, and makes maintenance more convenient. The layout inside the unit has undergone three-dimensional optimization design, with a compact layout and optimized external proportions. It requires less maintenance and repair space, occupies less room space, and significantly saves space.

2、 Compressor description:

1. Adopting a specially designed semi enclosed twin-screw compressor for high-temperature water source heat pump units, with a large capacity and high-efficiency motor, the compression ratio and displacement are higher than those of room temperature heat pump units, ensuring efficient and stable operation of the unit under high-temperature conditions.

2. Adopting high-precision machining of twin-screw rotors, aviation grade bearings are sturdy and wear-resistant, with stable performance, low noise, low vibration, and smooth operation.

3. Oil separator: The compressor is equipped with a three-stage high-efficiency oil separator, and a separator is designed on the pipeline to ensure extremely high oil separation efficiency even at very high exhaust speeds. By improving the oil supply and lubrication method, the exhaust oil content and exhaust superheat are effectively reduced, thereby further improving the oil separation effect.

4. Gradual or stepless adjustment can be achieved as needed: By using a slide valve for energy control, the refrigeration capacity can be infinitely adjusted within the range of 10% to 100%.

3、 Evaporator (optional high-efficiency falling film evaporator) features:

1. Adopting a shell and tube asymmetric structure design, where gaseous and liquid refrigerants flow through heat transfer copper tubes with different cross-sectional areas, the refrigerant circulates at the optimal and uniform flow rate in both liquid and gaseous states. This not only allows the refrigerant to evaporate fully, but also reduces the circulation resistance of the circuit.

2. Compared with symmetrical structures, asymmetric evaporators not only have higher heat transfer efficiency, but also have higher oil return efficiency.

3. High heat transfer efficiency vortex shaped internally threaded copper tube increases heat transfer area and refrigerant disturbance, improving heat transfer efficiency.

4. The design, manufacturing, and inspection of the evaporator comply with national standards and regulations for pressure vessels such as GB/150 "Steel Pressure Vessels" and JB/4750 "Pressure Vessels for Refrigeration Equipment".

4、 Condenser (optional high-efficiency falling film condenser) features:

1. The shell and tube heat exchanger adopts efficient double threaded copper tubes, which improves the heat exchange effect between the shell side refrigerant and the tube side cooling water, and increases the heat exchange efficiency by about 30% compared to ordinary heat transfer copper tubes.

2. The condenser adopts a unique air intake method to evenly distribute the flow of refrigerant, extend the condensation distance, and achieve the best heat transfer effect. It also increases the subcooling of the unit, thereby effectively improving the cycle efficiency of the unit. 3. The design, manufacturing, and inspection of the condenser comply with national standards and regulations for pressure vessels such as GB/150 "Steel Pressure Vessels" and JB/4750 "Pressure Vessels for Refrigeration Equipment".

5、 Control cabinet:

1. The start-up and microcomputer control parts of the high-temperature water source heat pump unit are integrated into the same control cabinet, located at the front of the unit, for easy operation by on-site operators in the machine room and between units. All electrical repairs can be carried out at the front of the unit.

2. The electrical control box is made of high-quality steel plate, and its outer surface has been galvanized and powder coated to make it resistant to weather and effectively protect the electrical components of the unit.

For the safety of operators, once the host is powered on, operators will not be able to open the isolation board between the control and electrical components to ensure their safety.

6、 Control system:

1. Adopting Siemens PLC new control system, it has a good human-machine interface, excellent control adjustment function, strong expansion ability, monitoring and management ability, and extremely strong compatibility. Multiple expansion accessories, adding remote and group control functions.

2. Friendly human-machine interface: The operation screen is embedded in the unit for convenient operation and good protection. Fully computer-controlled, achieving unmanned operation. The intuitive LCD interface displays data and parameter adjustments in multiple languages and menus. According to Clement's tradition, the press status and parameters have separate intuitive displays, making the operation situation clear at a glance.

3. The microcomputer intelligent controller has complete fault protection, alarm, recording and analysis functions, including high and low voltage switch, phase loss, reverse phase, overload, overcurrent, overheating, exhaust temperature, water flow, antifreeze and other protection functions. It also realizes fault recording, alarm display and other functions

7、 Specialized heating for hot water above 80 ℃:

The high-temperature water source heat pump unit uses a single environmentally friendly refrigerant R134A or a dedicated high-temperature heat pump refrigerant to produce 80 ℃ high-temperature hot water by utilizing low-grade energy from 10 ℃ -45 ℃ inlet water on the water source side, meeting the heating needs of building radiators at the end and industrial high-temperature hot water demand. Can directly replace coal-fired and gas-fired boilers, environmentally friendly, efficient and energy-saving.

8、 Electronic expansion valve:

The high-temperature water source heat pump unit adopts internationally renowned brand electronic expansion valves, which have high sensitivity and precise control. The refrigerant flow can be quickly adjusted according to actual working conditions, improving the full load and partial load performance of the high-temperature water source heat pump unit.

9、 Efficient economic device energy-saving and oil cooler technology:

1. The system is equipped with a high-performance economizer, and the application of air replenishment and enthalpy increase technology increases subcooling and improves unit performance.
2. Specially designed oil cooler, using refrigerant cooling to avoid poor lubrication of the system caused by high oil temperature.
