Product Desciption
Water Cooled Chiller Hanbell Bitzer Screw Compressor Water Chiller
1. Eurostars water cooled commercial screw chiller main components
(1)Compressor
*The screw compressors are of two-shaft rotary displacement design with the latest and advanced 5:6 patented screw rotors to improve work efficiency.
*Screw compressors have few parts, no wearing parts, stable and reliable operation, long life.
*Rod-type compressors have a volumetric design with a small clearance volume, small friction losses, and high operating efficiency.
*The refrigerant circuit and control circuit are completely independent ,can be used alternately according to loading condition, which can effectively extend the service life. It has the advantages of high efficiency, low energy consumption, low noise, low vibration, wear resistance and high reliability.
(2)Condenser
*Shell and tube condenser, with copper tubes optimizes efficient heat exchange between the chiller and cooling tower.
*The cover plates at both ends are removable, can be removed to clean the copper tube, effectively ensure the safe operation of the system. The condenser has passed the national pressure vessel inspection.
(3)Evaporator
*Shell and tube type evaporator is equipped with refrigerant shunting device, which can evenly distribute the refrigerant to each heat exchange tube, improve heat exchange efficiency.
*The exterior of the evaporator is affixed with thermal insulation material to avoid the loss of cooling capacity.
(4)Thermal Expansion Valve
*Adopts the world-renowned branded thermal expansion valve for higher control accuracy, wider adjustment range and faster response.
*Under any working conditions, the heat exchange area of the evaporator can be fully utilized, the heat exchange is more sufficient, and the efficiency is higher, which can ensure the reliability of the refrigeration system.
(5)Intellectualized Controller
*Adopt micro computer touch screen control, can operate via centralized manage system; The system can monitor the water temperature, capacity status while running. The water temperature can be controlled according to the water outlet temperature. Trouble shooting code may display on the touch screen automatically when the system is abnormal.
*Whole system can realize remote operation.
2.What Are Water Cooled Chiller Systems
An alternative to air-cooled systems and rooftop units, water cooled chiller systems are typically used for industrial and commercial applications for their significant energy savings benefits, and to aid companies in their attempts in reducing carbon emissions.
(1)How Do They Differ From Air-Cooled Systems?
Though water and air cooled systems share many components in common - evaporator, condenser, compressor, expansion valve - unlike air-cooled systems, which disperse heat via an air-cooled condenser coil, water cooled chiller systems use water to absorb heat, dispersing it into the air through a cooling tower. It is this component that gives water cooled systems an efficiency advantage over air-cooled and rooftop systems, from 10-100% depending on the setup.
(2)Why Are They So Much More Efficient?
Water is more energy dense than air, providing more efficient cooling than traditional air-cooled options. However these systems come with one main drawback: A higher equipment cost. They are typically used in locations larger than 200,000 square feet, where cooling needs will quickly offset the added cost of equipment. Other applications include industrial use, such as the cooling of plastics and metals, and the cooling of small and large multi-storied structures like universities, hospitals, and large office buildings, as the systems don't require ducts to push air through multiple stories. With system sizes ranging from 20 tons to several thousand, applications are wide and varied.

6.Protection devices in a Eurostars chiller
(1)Motor overload protection
Including for compressor motors, water pump motors.
There are some situations that will cause damage to motors in an industrial chiller, such as instable voltage, ambient temperature too high which mostly caused by poor ventilation, returning water temperature too high, etc. In these cases the motor running current will get higher than its safe range, which might damage the motor if keep it working. Built in protection for overload will shut down the chiller and warn you if the motors are working unhealthily.
(2)Compressor motor overheat protection
Compressor is the heart of an industrial chiller, it reflects problem of the whole chiller unit. The situation causes compressor motor overheat includes poor ventilation, dusty condenser, refrigerant circuit blocking, lack of refrigerant, etc.
This alarm reminds you to check through the chiller unit, prevent it from burning out because of unhealthy working condition.
(3)Discharge temperature overhigh protection
Discharge temperature overhigh normally caused by high suction temperature, high compressor motor temperature, lack of refrigerant, etc. It works as supplementary of compressor motor overheat.
(4)High&low pressure protection
High pressure normally caused by poor ventilation, dusty condenser, refrigerant circuit blocking, etc.
Low temperature caused by lack of refrigerant, system blocking and so on.
(5)Returning water overheat protection
Chiller supply cold water to cool the production process or for commercial cooling, normally the returning water temperature will be 3ºC to 8ºC higher than supplied water. If the chiller is not creating cooling energy, or the chiller capacity is not enough for the application, the temperature in the circuit will get higher and higher. This will cause damage for the production even the equipment.
While a chiller got an alarm function for returning water temperature, we can learn the situation promptly and make reaction.
(6)Low water flow/level protection
For a chiller with no open-circuit water tank, there will be a water flow switch to make sure the water circuit is working, preventing both production process and chiller unit from harmed by circuit blocking or water leaking.
(7)Phase protection
If an industrial chiller was falsely wired, motors will revert, which is a serious problem for all the motors. Phase protection will remind you to connect the power in a right way.
(8)Anti-freezing protection
This function prevents the water in the circuit from freezing, so to make sure the cooling circuit working in a healthy condition.
