Product Description:
Water-cooled screw chiller is a kind of refrigeration equipment for industrial use, mainly used to provide cooling and air conditioning services for large buildings such as factories, commercial centers, and office buildings. It lowers the temperature of water by circulating refrigerant, so that cold water is delivered to the area that needs to be cooled to achieve the effect of cooling, dehumidification and keeping the air fresh.
The main components of a water-cooled screw chiller are compressors, condensers, evaporators, and throttle valves. Among them, the screw compressor is the core part of the whole system, which increases its temperature and pressure by compressing the refrigerant, makes it dissipate heat in the condenser and cools it down, and then absorbs heat in the evaporator and lowers the temperature, forming cold water recirculation use.
The water-cooled screw chiller has the characteristics of high cooling efficiency, large cooling capacity, stable operation, low noise, and easy maintenance. It is suitable for places that require a lot of cooling, such as large buildings and industrial manufacturing enterprises. However, its installation and use costs are high, and it requires a large space and power energy support, so it is generally used for large-scale projects and commercial purposes.

Working Principle:
The working principle of the water-cooled screw chiller mainly
includes four processes of compression, condensation, expansion and
evaporation.
1.Compression process: Under the action of the screw compressor, the refrigerant is
compressed into a high-temperature and high-pressure gas, while
absorbing the surrounding heat.
2.Condensation process: High-temperature and high-pressure
refrigerant enters the condenser, and through contact with cold
water or surrounding air, it emits heat and cools into a
high-pressure liquid.
3.Expansion process: The high-pressure liquid refrigerant enters the evaporator through
the throttle valve, the pressure drops suddenly, and the liquid
refrigerant expands into a low-pressure refrigerant while absorbing
the surrounding heat.
4.Evaporation process: The low-pressure refrigerant enters the evaporator, absorbs
surrounding heat through contact with water or air, turns into a
low-temperature and low-pressure refrigerant, and returns to the
compression process.
Through such a cycle process, the water-cooled screw chiller can
deliver cold water to the area that needs to be cooled to achieve
the effects of cooling, dehumidification and keeping the air fresh.
At the same time, the water-cooled screw chiller will also emit a
certain amount of heat, which needs to be dissipated through
cooling towers or other heat dissipation equipment to ensure the
normal operation of the system.

Chiller low pressure alarm solution?
Chiller low pressure alarms can be caused by a number of reasons, here are a few possible solutions:
1. Check whether the refrigerant of the chiller is sufficient: If the refrigerant of the chiller is insufficient, it will cause a low pressure alarm. The problem can be fixed by checking the refrigerant charge of the chiller, or by using a refrigerant leak detector to find the leak and fix it.
2. Check the cleanliness of the condenser and evaporator: If the condenser and evaporator are polluted or blocked, the cooling effect will decrease, and a low pressure alarm will be generated. The problem can be solved by cleaning the condenser and evaporator.
3. Check whether the water pump of the chiller is running normally: If the water pump of the chiller fails or does not operate normally, it will cause poor refrigeration cycle and generate a low pressure alarm. The problem can be solved by checking the motor, impeller, bearing and other parts of the water pump, and repairing or replacing the problematic parts.
4. Check whether the electrical control system of the chiller is normal: If the electrical control system of the chiller fails or does not operate normally, it will cause poor refrigeration cycle and generate a low pressure alarm. The problem can be solved by checking the relays, controllers, sensors and other parts in the electrical control system, and repairing or replacing the problematic parts.
It should be noted that in order to ensure the normal operation of the chiller, equipment maintenance and maintenance should be carried out regularly, the condenser and evaporator should be cleaned in time, and the refrigerant charge and water pump operation should be checked to avoid failures. At the same time, for some complicated faults, it is best to have professional technicians repair and deal with them.
