Water source heat pump central air-conditioning system operating principle
Geothermal water source heat pump air conditioning system uses the lake, the water, groundwater and geothermal water resources. With the help of compressing system, low-grade thermal energy of the water can be "taken out" and be transported into interior room by consuming small amount of energy in winter; in summer, indoor heat can be "released " into the water as cooling purposes.
Wider environment utilization 
Compared with air-cooled heat pump chiller , water source heat pump chiller is less influenced by environmental temperature. When heating in winter with no frost and defrosting interference , heating water temperature is more stable for cooling and heating in harsh environments without decay .
Running more stably
When water source heat pump chiller operates , the water temperature is quite stable. This makes the chiller runs more stable and reliable in cooling and heating work.
Recyclable cooled water chiller system

Due to the increasingly energy shortage, waste heat recycling will have a long-term economic value. Basing on this fact, our enterprise developed a heat recycling chiller system, which can fully recycle the condensing waste heat originally released into the environment, which can be used in hotels , dormitories , toiletries and other occasions; If heat recycling technical parameters are needed, please contact our technical department to obtain.

Small vortex chiller 

The vortex chiller adopts import efficient and flexible scroll compressor. With the independent modular design, it brings various number of capacity combinations, easy accessibility and high reliability .

Balanced running performance and extended service life
Many of the chiller with compression, microcomputer automatic memory will be per compressor operation time, start the next time it will be activated running less time compressor. Similar in the discharge of the need, but also will be preferential the operation longer time to uninstall chiller, in order to achieve the balance of each compressor operation, extend the service life of the machine.
More energy efficiency
Water source heat pump chiller has high energy efficiency. Compared with general central air conditioning chillers, water source heat pump units can save over than 30% of energy, and it is one of the most energy-efficient central air conditioning chiller and in line with the national energy saving policy for customers to save considerable operating costs .
Compared with the central air-conditioning system applied water-cooled chillers,  the one with water source heat pump piping system is relatively more simple, and the systems does not need cooling tower for cooling and does not need boiler room for heating. This will bring more pollution reduction and less urban noise pollution. conversion of cooling and heating can be simply achieved by switching the water pipeline valve.
Environmental Friendly
In order to better protect the atmosphere, it can produce green environmental protection cooling medium refrigeration and air conditioning equipment not only in adopts HFC407C and HFC134a,but also in HCFC22.
Y-△depressurization start mode
Half screw condensing water chillers use Y-△depressurization start mode. The starting electric current is only about 1.5 to 2 times as run-time current which greatly reducing the impact to the grid 
Automatic capacity adjustment 
According to the air conditioning' demand, screw air-cooled chiller can automatically adjust load capacity. The standard chiller capacity adjustment is implemented by segmented or non-polar uninstalling method. One single machine can realize four different compressor capacity level, which are 100%, 75%, 50% and 25%. 25% level is used to start compressors. The induction capacity control can be achieved in the range of 25 to 100%. According to customer needs, the chiller capacity can be customized in a range from 15% to 100% smoothly.
Energy conservation
The waste heat, which is generated from the pump cooling system, can be used to produce domestic hot water without additional consumption of electricity and fuel; almost zero cost ; no pollution ; no need to add other devices. The only thing is to directly connect water pipeline to access hot water.
Remote control 
Each chiller is occupied with remote control function. The computer controller is equipped with RS485 standard communication interfaces, open communication protocol. This will allow all kinds of building monitoring system connected and remote monitoring.
Large screw condensing chiller 
Twin-screw compressor applies the world's most advanced 4th generation asymmetric patent tooth rotor machining by the British HOLROYD rotor and then grinding precision by the German KLINGELNBERG precision rotor grinding machine. This greatly reduces leakage and cooling loss. The usage of advanced three-stage oil network makes the oil filter ratio up to 99.7%, which greatly ensure machine oil return to the compressor , the wide range of built-in protection can ensure the compressor safe operation including small vibration , low noise and high efficiency.
Except compressor refrigeration, other major components are imported quality products, such as the expansion valve , solenoid valve , filter drier , etc, which are all European and American quality products , have reliable performance and precise control .
Touch screen computer interface 
The chiller is controlled by micro-computerized controller, and all are equipped with Germany Siemens PLC imported controller. The accuracy and intelligentize truly achieve perfect control of whole machine in order to ensure safe operation of the unit and the purpose of effective energy conservation. The machine is equipped with touch-screen interface,which is simple and customer-friendly.
Test center 

The enterprise has a well-operated testing center , each air-conditioning unit have been injected refrigerant and refrigerant oil before leaving factory. After undergoing a rigorous simulation of the standard conditions and maximum operating mode detection, expansion valve can be adjusted to the best condition.
