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:

1The unit structure layout 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. According to the needs, it can be adjusted in stages or continuously: energy control can be achieved through a slide valve, which can increase the cooling capacity10%--100%Stepless adjustment within the range.

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

1Adopting 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 regardless of whether it is in liquid or gas state. This not only allows the refrigerant to evaporate fully, but also reduces the circulation resistance of the circuit.

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

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

4The design, manufacturing, and inspection of the evaporator all comply withGB/150Steel Pressure VesselsJB/4750National standards and regulations for pressure vessels such as "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 up to30%about.

2. The condenser adopts a unique 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 all comply withGB/150Steel Pressure VesselsJB/4750National standards and regulations for pressure vessels such as "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, making it easy for on-site operators to operate 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.

3. 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:

1Using SiemensPLCThe new control system has a good human-machine interface, excellent control and adjustment functions, strong scalability, monitoring and management capabilities, and extremely strong compatibility. Multiple expansion accessories, adding remote and group control functions.

2Friendly human-machine interface: The operation screen is embedded in the unit for convenient operation and good protection. Fully computer-controlled, achieving unmanned operation. visualLCDThe 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.

3The 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 the recording and alarm display of faults

7、 Specialized heating80Hot water above ℃:
