Centrifugal water source heat pump unit: powerful cooling, low energy consumption, high energy efficiency and money saving

Centrifugal water source heat pump unit with two-stage centrifugal compressor, high efficiency and more stability

Two-stage centrifugal compressor, high efficiency, more stable

The two-stage centrifugal compressor is not easy to surge; the system economizer supplies air between the compressor stages, and the cooling capacity is increased by at least 10%.

Intelligently judge the surge area, adjust the speed and IGV in time, avoid the occurrence of surge, and make the operation more stable and safer.

Gear speed-increasing drive, the impeller volume is smaller, the motor starting torque is small, and the downtime is short.

The motor is integrated with the compressor, and the running noise is low, and there is no risk of leakage.

The motor is cooled by liquid refrigerant, with low operating temperature and high efficiency.

Use high-strength ball/roller bearings, not afraid of compressor emergency stop.

The complete oil circuit system of the centrifugal water source heat pump unit is safer and more reliable

Perfect oil circuit system, safer and more reliable

Using an independent oil return system (ejection pump oil return), it can ensure timely oil return under any load conditions.

The unit has built-in oil cooler, which is cooled by refrigerant, which is safe and reliable.

The oil pump is built into the compressor oil sump, eliminating the risk of oil pump leakage.

High energy efficiency heat exchanger with excellent performance

The use of self-developed and produced high-efficiency spray heat exchangers, and the use of precise liquid level control technology, ensures that the evaporator is always in a high-efficiency heat exchange state.

The condenser adopts droplet separation technology to ensure high energy efficiency and sufficient heat exchange of the condensing heat exchange tube.

COP value up to 6.3

Magnetic levitation oil-free technology for centrifugal water source heat pump unit, energy saving and noise reduction

With heat recovery device, free hot water

Using self-developed heat recovery device, the waste heat generated in the refrigeration process is recovered. While providing customers with cold water, a large amount of hot water can also be supplied free of charge.

Centrifugal water source heat pump unit condensing heat energy recovery, free and practical

Environmentally friendly refrigerant with good overall performance

The mainstream environmentally friendly refrigerant R134a is used, which has good comprehensive performance, and the ozone depletion value (ODP) is 0.

The unique throttling technology of centrifugal water source heat pump unit makes the unit more energy efficient

Unique throttling technology, the unit is more energy efficient

The self-developed multi-stage throttling device has an adaptive function. When the load changes and the working conditions change, the refrigerant supply can be adjusted in time without lag, ensuring that the unit is in a state of high energy efficiency at any time.

Integrated control of centrifugal water source heat pump unit, easier management

Integrated control, easier management

The fully automatic microcomputer touch control system is adopted to clearly display various operating data and timely feedback various maintenance information, without the need for full-time operators. The unit control system can be connected to the user's central control system, so that the unit operation can be fully understood at any time.
