JLSF-100HP Air Cooled Water Chiller Using Denmark Danfoss Scroll Compressor
Product Description:
Air-cooled scroll chiller is a device used in refrigeration and
air-conditioning systems that uses air-cooled condenser and scroll
compressor technology.
Air-cooled scroll chillers utilize an air-cooled condenser to
dissipate heat. The condenser is an important component in the
refrigeration cycle. It cools and converts high-temperature and
high-pressure refrigerant gas into high-pressure liquid.
Traditional chillers usually use a water-cooled condenser to
dissipate heat and need to be connected to a cooling tower or other
water source for cooling. The air-cooled scroll chiller uses a fan
to blow across the fins on the condenser surface to take away the
heat and achieve heat dissipation.
Air-cooled scroll chillers have several advantages over traditional
water-cooled chillers. First, it does not need to be connected to
an external water source, making installation more convenient.
Secondly, since there are no additional equipment such as water
pumps and cooling towers, the system is simpler and takes up less
space. In addition, air-cooled scroll chillers usually have a high
energy efficiency ratio and can provide stable cooling effects.
Product Features:
Air-cooled scroll chiller is a chiller that uses air-cooled
condenser and scroll compressor technology. Here are some common
features:
1. High efficiency and energy saving: The air-cooled scroll chiller uses an efficient scroll compressor
to provide a high energy efficiency ratio and achieve energy-saving
operation. They typically have lower power consumption and better
cooling, reducing energy consumption and operating costs.
2. Compact design: This type of chiller usually has a compact structural design and takes up relatively small space, making it suitable for places with limited installation space. Their compactness makes them more flexible and convenient in commercial and industrial applications.
3. Rapid cooling: The air-cooled condenser can quickly dissipate heat through fans and heat sinks, providing a fast and effective cooling effect. This makes the air-cooled scroll chiller perform well in scenarios where rapid cooling is required, such as in high-temperature environments or applications that require rapid cooling.
4. Simplified installation: Air-cooled scroll chillers are relatively simple to install since they do not require connection to an external water source or cooling tower. This reduces the complexity of piping layout and water system configuration during installation, saving time and labor costs.
5. Automated control: Many air-cooled scroll chillers are equipped with advanced automated control systems, which can achieve precise temperature control and intelligent operation. These control systems usually have monitoring and regulating functions to ensure stable operation and optimal performance of the equipment.
6. Wide adaptability: Air-cooled scroll chillers are suitable for various refrigeration and air-conditioning application scenarios, including commercial buildings, offices, hotels, medical facilities, industrial plants, etc. They can meet refrigeration needs of different sizes and needs, and have good adaptability and flexibility.
Working Principle:
The working principle of the air-cooled scroll chiller can be divided into two main parts: refrigeration cycle and heat dissipation cycle.
Refrigeration cycle part:
1. Compression: The core of the refrigeration cycle is the scroll compressor. The
compressor sucks in low-temperature and low-pressure refrigerant
gas, and then increases its pressure and temperature through
rotation and compression.
2. Condensation: The compressed high-temperature and high-pressure refrigerant gas
enters the air-cooled condenser. In the condenser, a cooling fan
blows outdoor air over the condenser's fins, causing the
refrigerant gas to dissipate heat and cool down. When the
refrigerant gas is cooled, it turns into a high-pressure liquid.
3. Expansion: High-pressure liquid refrigerant enters the evaporator through the expansion valve (throttle device). The function of the expansion valve is to reduce the pressure of the refrigerant, causing it to expand rapidly, thereby reducing the temperature and pressure.
Heat dissipation cycle part:
1. Evaporation: The expanded low-temperature and low-pressure refrigerant enters
the evaporator. A finned tube or radiator is installed inside the
evaporator. By contacting the water or air to be cooled, it absorbs
heat and cools the water or air.
2. Cold water supply: The water cooled in the evaporator is sent to the equipment or
system that needs to be cooled to absorb heat and reduce the
temperature.
3. Cooling cycle: The cold water is transported back to the equipment or system to be cooled through the circulation pump and circulated for cooling, forming a closed-loop cycle.
During the entire process, the refrigerant completes the cycle of compression, condensation, expansion and evaporation under the action of the compressor, absorbing and releasing heat, thereby achieving the refrigeration effect of cold water. The air-cooled condenser removes heat through a fan to ensure that the refrigerant can continue to cool and circulate during the cycle.

How does the evaporator of an air-cooled scroll chiller absorb heat through contact with water or air?
The process of the evaporator of an air-cooled scroll chiller absorbing heat through contact with water or air can be carried out in the following two ways:
1.Water cooling method:
In water cooling, the interior of the evaporator usually contains a
set of tubes or finned tubes that absorb heat by circulating cold
water. Water is transported from the cold water system to the pipes
in the evaporator through a circulation pump. Refrigerant flows
inside the evaporator over the outer surfaces of these tubes, while
cold water flows through the inside of the tubes. Due to the low
temperature and low pressure of the refrigerant, it will absorb
heat from the outer surface of the cold water pipe, lower the
temperature of the cold water, and take the heat away. In this way,
the cold water can be recirculated, while the refrigerant continues
the cycle of evaporation and heat absorption.
2.Air cooling method:
In the air cooling mode, the pipe surface inside the evaporator is
exposed to the outside air. Refrigerant flows inside the tubes
while a fan blows outside air across the evaporator's tube
surfaces. Through contact with the outside air, the refrigerant
absorbs heat from the pipe surface, causing the pipe surface to
cool and carry the heat away. In this way, the refrigerant can
continue the cycle of evaporation and heat absorption.
Whether it is water cooling or air cooling, the evaporator takes advantage of the refrigerant's ability to absorb heat during the evaporation process. By contacting water or air, it absorbs heat from the water or air to achieve a cooling effect. The specific method used depends on the needs of the application and the requirements of the design.
