Molding, Bottle Blowing
Product Description:
Water-Cooled Scroll Chiller is a cooling device used in
refrigeration and air-conditioning systems. Its working principle
is to use a compressor to compress the refrigerant into a
high-temperature and high-pressure gas, and then cool it into a
low-temperature and low-pressure gas through a heat exchanger, and
then pass through After the expansion valve is adjusted, it enters
the evaporator to make it absorb the heat in the air and cool it
down, and finally passes through the compressor to and fro to form
a refrigeration cycle.
Different from closed-type chillers, water-cooled open-type
chillers use public water sources (such as tap water) in the
cooling process, and circulate water through cooling towers and
cooling water pipelines to cool the refrigerant, thereby achieving
cooling effects. At the same time, the cooling water of the
water-cooled open chiller will be sprayed on the cooling tower
during the cooling process to form water mist, so it is called
"open type".
Production Features:
Water-cooled scroll chiller is a commonly used type of chiller with
the following characteristics:
1. High efficiency and energy saving: The water-cooled scroll chiller uses a scroll compressor as the
core component, which has the characteristics of high efficiency
and energy saving. The scroll compressor uses a scroll-shaped
compression chamber, which can provide high compression efficiency
and low power consumption, allowing the chiller to cool at a higher
efficiency during operation, thus saving energy and operating
costs.
2. Wide range of applications: Water-cooled scroll chillers are suitable for applications in
various industrial and commercial fields, including office
buildings, shopping malls, hotels, hospitals, factories, etc. They
can provide a wide range of cooling capabilities to meet the
cooling needs of different locations and needs.
3. Stable and reliable: Water-cooled scroll chillers usually have solid and reliable
design and manufacturing quality, and can operate stably for a long
time. The scroll compressor has a simple structure and no moving
parts, which reduces mechanical failures and maintenance
requirements and improves the reliability and stability of the
equipment.
4. Precise control: Water-cooled scroll chillers are equipped with advanced control
systems that enable precise temperature and capacity control. Users
can set and adjust the cooling temperature according to actual
needs to meet specific cooling requirements. The control system can
also monitor and adjust the operating status of the chiller to
ensure stable and efficient operation.
5. Compact design: Water-cooled scroll chillers usually have a compact structure and
a small footprint, making them suitable for installation in places
with limited space. This allows them to still provide powerful
cooling capabilities in space-constrained environments and
facilitate maintenance and operation.
It is important to note that specific water-cooled scroll chiller
features may vary depending on the manufacturer and model. When
selecting and using a chiller, it is recommended to refer to the
product specifications and information provided by the manufacturer
to understand its specific features and scope of application.
Working Principle:
Water-Cooled Scroll Chiller is a cooling device used in
refrigeration and air-conditioning systems, and its working
principle is as follows:
Compression cycle: The refrigeration cycle of the water-cooled open chiller is
realized by a compressor. The compressor sucks in low-temperature
and low-pressure refrigerant gas and compresses it into
high-temperature and high-pressure gas. Such high-temperature and
high-pressure gas is cooled by a heat exchanger to become a
high-temperature and high-pressure gas.
Heat exchange cycle: The high temperature and high pressure gas is cooled by water
circulation in the heat exchanger. In this way, the refrigerant gas
becomes a high-temperature and low-pressure gas.
Expansion cycle: The high-temperature and low-pressure refrigerant gas enters the
evaporator through the expansion valve, thereby forming a
low-temperature and low-pressure refrigerant gas. In the
evaporator, the refrigerant gas absorbs heat from the air, thereby
cooling the air.
Cooling cycle: After cooling in the evaporator, the refrigerant gas is drawn
again into the compressor, thus starting a new refrigeration cycle.
Water circulation: The water circulation in the water-cooled open chiller is realized
through the cooling tower and the cooling water pipeline. The
refrigerant gas exchanges heat with the cooling water in the heat
exchanger, transfers the heat to the cooling water, and raises the
temperature of the cooling water. The cooling water passes through
the spray system of the cooling tower to form water mist, which
dissipates heat into the air. After the cooling water passes
through the cooling tower, it is circulated to the heat exchanger
again through the water pump to form a water cycle.

How to improve the cooling capacity of chillers under high ambient
temperatures?
In high ambient temperatures, to improve the cooling capacity of
the chiller, the following methods can be adopted:
1. Increase the temperature difference of the cooling water: The cooling capacity of the chiller is mainly achieved through the
heat exchange between the cooling water and the condenser. At high
ambient temperatures, if the temperature difference of the cooling
water (that is, the difference between the cooling water inlet
temperature and the cooling water outlet temperature) can be
increased, it will help to improve the cooling effect. Therefore,
you can consider increasing the flow of cooling water or using a
lower temperature water source to increase the temperature
difference.
2. Increase the flow of cooling water: Increasing the flow of cooling water can improve cooling
efficiency, thereby increasing refrigeration capacity. By
increasing the flow rate of cooling water, the heat exchange area
between the cooling water and the condenser can be increased,
speeding up the transfer and discharge of heat, thereby improving
the cooling effect.
3. Optimize condenser design: The condenser is a key part of the chiller, and optimizing its
design can improve the cooling capacity. For example, increasing
the heat exchange area of the condenser, improving the flow pattern
between cooling water and the condenser, or using efficient
condenser materials can improve the condensation effect and thereby
improve the refrigeration capacity.
4. Use auxiliary cooling equipment: Under high ambient temperatures, you can consider using auxiliary
cooling equipment to help reduce the temperature of the cooling
water, thereby increasing the cooling capacity of the chiller. For
example, equipment such as cooling towers, cooling coils, or
evaporative coolers can be used to reduce the temperature of the
cooling water to a lower level to increase the cooling effect.
5. Consider chiller models for high-temperature environments: In high-temperature environments, some chiller models may have
designs and configurations that are more suitable for
high-temperature environments. These models generally have higher
cooling capacity and better adaptability, providing more reliable
cooling in high-temperature environments.
It should be noted that in actual applications, the feasibility and
effect of the above methods may vary depending on the model,
specifications and environmental conditions of the chiller.
Therefore, when increasing the cooling capacity of a chiller, it is
recommended to refer to the guidelines and recommendations provided
by the manufacturer of the chiller to ensure correct operation and
adjustment and to achieve the best cooling effect.
