JLSF-25HP Air Cooled Water Chiller With Insulated Tank For Paper Industry
Product Description:
The air-cooled integrated chiller is a cooling device that integrates a chiller, an insulated water tank and an external circulation pump. It adopts an air-cooled cooling method, and the heat is discharged from the cooling system through a fan without an additional cooling water source. The integrated design of the air-cooled integrated chiller makes installation easier for users.
Product Features:
The following are some characteristics and application scenarios of air-cooled integrated chillers:
1. Simplified installation: The air-cooled integrated chiller integrates a cooling tower and a chiller, and the installation is relatively simple without cumbersome piping and cooling water systems.
2. Space-saving: Compared with traditional cooling systems, air-cooled integrated chillers take up less space and are suitable for places with limited space.
3. Built-in fan: The air-cooled integrated chiller has a built-in fan, and the heat is discharged through the operation of the fan, without additional cooling water pumps and cooling towers.
4. Independent operation: The air-cooled integrated chiller can operate independently without relying on an external cooling water source, and is suitable for some environments where cooling water cannot be provided.
Working Principle:
The main components of an air-cooled chiller include a compressor, an air condenser, an expansion valve, and an evaporator. Here is a basic overview of its workflow:
1.The compressor takes in low-pressure, low-temperature refrigerant gas and compresses it into high-pressure, high-temperature gas.
2.This high-temperature, high-pressure refrigerant gas enters the air condenser, exchanges heat with the ambient air, and discharges heat to the environment, while the refrigerant condenses from a gaseous state to a liquid state.
3.The high-pressure refrigerant liquid passes through the expansion valve, the pressure suddenly drops, and it turns into a low-pressure and low-temperature refrigerant liquid.
4.The low-temperature and low-pressure refrigerant liquid enters the evaporator, absorbs indoor heat, evaporates into a gaseous state by itself, and the indoor temperature drops to achieve the purpose of refrigeration.
5.The refrigerant gas is sucked into the compressor again to complete a cycle.
The advantages of air-cooled chillers include simple installation, no need for cooling towers and cooling water pumps, and low maintenance costs. However, its efficiency is lower than that of water-cooled chillers, especially at high ambient temperatures, and its efficiency will be further reduced

Why does an air-cooled chiller need a large external water tank?
There are several main reasons why air-cooled chillers are equipped with a large external water tank:
1. Provide additional cooling capacity: An external water tank can provide a larger volume, thereby increasing the thermal capacity of the cooling system. This means the chiller can handle larger heat loads and provide more cooling capacity when needed. A large-capacity water tank can store more cooling water, allowing the system to provide a more stable cooling effect during high-load operation.
2. Increase the heat exchange time of the cooling water: The external water tank can provide a longer heat exchange time, giving the cooling water more time to exchange heat with the condenser. This increases the cooling effect and makes the cooling system more efficient.
3. Reduce cooling water temperature: A large-capacity external water tank can hold more cooling water, making the temperature of the cooling water rise more slowly. This ensures that the temperature of the cooling water is always kept at a lower level, providing a more stable cooling effect.
4. Reduce the circulation frequency of the cooling system: The external water tank can serve as a storage buffer for cooling water, reducing the circulation frequency of the cooling system. This helps extend the life of the cooling system and reduces energy consumption.
5. Convenient maintenance and cleaning: The external water tank can be maintained and cleaned independently of the cooling unit, making it convenient for operators to perform daily maintenance and inspections. At the same time, because the water tank is located outdoors, it also reduces the occupation of indoor space and the generation of noise.
In summary, equipped with a large external water tank can provide additional cooling capacity, increase heat exchange time, lower cooling water temperature, reduce cycle frequency, and facilitate maintenance and cleaning. These advantages allow the chiller to provide cooling more efficiently and reliably.
