Water Chiller Unit

● Shanli water chiller unit carries a variety of water cooled chillers that suit a wide range of industries.

● Water cooled chillers absorb heat from process water and transfer it to a separate water source such as a cooling tower, river, pond, etc.

● They are also considered when a cooling tower is already in place, or where the customer requires optimum efficiency of power consumption.

● Water cooled chillers require condenser water treatment to eliminate mineral buildup.

● Mineral deposits create poor heat transfer situations, that reduce the efficiency of the unit.

● Water chiller unit patented awarded design, CE certification.

● Use widely in overseas markets,enjoying extremely high occupation rate of market and reputation.

● The temperature of the water can be controlled to be between the working environment.

● Perfect after-sales service. Warranty of 12 months.

● Excellent specialization in thermolysis, splendid performance of cooled radiator.

● High performance cost, energy saving.

Water chiller is a kind of water cooling equipment, which can provide constant temperature, constant flow and constant pressure cooling water equipment.

The working principle of the chiller is to inject a certain amount of water into the water tank in the chiller, cool the water through the chiller refrigeration system, and then send the low temperature cooling water to the equipment to be cooled by the water pump. The chilled water of the chiller takes away the heat and returns to the water tank after the temperature rises, and then cools the water through the refrigeration system.

The cooling water temperature can be automatically adjusted according to requirements, and long-term use can save water. Therefore, the chiller is a standard energy-saving equipment. The popular point is that it can always output ice water that is lower than the ambient temperature. You can use it wherever you need to cool down, either directly or indirectly.

Working principle of industrial chiller: The industrial chiller can provide chilled water with constant temperature, constant flow and constant pressure. During operation, the chiller first injects a certain amount of water into the internal water tank of the machine, cools the water through the chiller refrigeration system, and then the water pump injects the low temperature frozen water into the equipment to be cooled. The chilled water takes away the heat inside the machine, and returns the high temperature hot water to the water tank again for cooling. In this way, the circulating exchange cooling can achieve the function of cooling the equipment.

The industrial chiller consists of compressor, condenser, evaporator, expansion valve and other accessories:

1. Evaporator: when the freon liquid of the refrigeration system enters the expansion valve for throttling, it is sent to the evaporator, which belongs to the vaporization process. At this time, it needs to absorb a lot of heat to gradually reduce the temperature of the cooled price and quality, so as to achieve the cooling effect.

2. Condenser: the high temperature and high pressure freon of the refrigeration system enters the condenser after coming out of the compressor, releasing a lot of heat to the cooling medium and being cooled for liquefaction.

3. Compressor: In the chiller system, the compressor is the power to ensure refrigeration. The compressor is used to increase the pressure of the refrigerant in the system, so that the refrigerant can circulate in the refrigeration system to achieve the refrigeration purpose.

4. Expansion valve: In the refrigerant system flow chart of the chiller, we found that there is a small component called thermal expansion valve between the outlet of the condenser and the inlet of the evaporator. It is a throttling and depressurizing component, which reduces the refrigerant condensation pressure to the evaporation pressure. Therefore, it plays an essential role in the refrigeration system. It, together with the refrigeration compressor, evaporator, and condenser, is called the four major components of the refrigeration system.

Other accessories: including drying filter and high and low pressure controller The drying filter is non detachable, and its internal structure is molecular sieve, which can remove a small amount of impurities and water in the pipeline, so as to purify the system. High and low pressure controller plays a protective role in the refrigeration system.
