Double compressor air cooled packaged chiller - BS Series(-5℃)- 10AD

BS Series Air cooled packaged chiller

 

The air cooled packaged chiller It integrates core components such as compressors, evaporators, condensers, and fans into a single cabinet. It has a compact size and saves installation space;

It relies on its built-in fans for forced heat dissipation, eliminating the need for an additional cooling water circulation system. It is suitable for scenarios with water scarcity or limited space.

With a high degree of structural integration and neat component layout, maintenance tasks such as daily cleaning and component inspection are more convenient, and frequent operations by professional teams are not needed.

Air cooled  packaged chiller Working Principle

Air-cooled box-type chillers achieve refrigeration through the circulation of refrigerants, with the core steps as follows:

The compressor compresses the low-temperature and low-pressure refrigerant gas into high-temperature and high-pressure gas.

The high-temperature and high-pressure gas enters the condenser, where the fan blows air to remove heat, and the gas is condensed into medium-temperature and high-pressure liquid.

The medium-temperature and high-pressure liquid is throttled by the expansion valve and converted into a low-temperature and low-pressure gas-liquid mixture.

The gas-liquid mixture enters the evaporator and undergoes heat exchange with the water (or other coolants) that needs to be cooled. After absorbing heat, the mixture evaporates into gas; at the same time, the temperature of the chilled water decreases and the water is delivered to the demand side.

The evaporated refrigerant gas returns to the compressor again, and the cycle repeats.

Core Advantages (Compared with Water-Cooled Type)

Compared with water-cooled chillers that require cooling towers, air-cooled box-type chillers have obvious advantages:

• No need for supporting cooling towers: It relies on air for heat dissipation, eliminating the installation, space occupation and maintenance costs of cooling towers.
• Flexible installation: With an integrated design and small size, it can be used only by connecting the power supply and water inlet/outlet pipes, making it suitable for scenarios with limited space.
• Convenient movement: Some small-sized equipment is equipped with rollers, allowing flexible movement to different workstations according to needs.
• Simple maintenance: It avoids problems such as scale and pipeline blockage in the cooling water system, and only requires regular cleaning of dust on the condenser.

 

Q1: What types of refrigerants can be used in a -5℃ air-cooled box-type chiller?

A1: Typically, R22 refrigerant can be used, and environmentally friendly refrigerants such as R407C and R134A can also be selected.

Q2: How to calculate and select the cooling capacity of a -5℃ air-cooled box-type chiller?

A2: The calculation of cooling capacity needs to take into account multiple factors, such as the heat generation of the equipment or space that needs cooling, ambient temperature, required cooling rate, etc. Generally speaking, the required cooling capacity can be initially estimated based on the power of the equipment, the heat load of the process, and other factors. When selecting a chiller, it is necessary to ensure that its cooling capacity is slightly greater than the actual required cooling load to ensure that the equipment can operate stably and efficiently.

Q3: What are the requirements for the operating environment of a -5℃ air-cooled box-type chiller?

A3: Usually, the ambient temperature range for operation is required to be between -7℃ and 43℃, and good ventilation should be maintained around the chiller to ensure that the condenser can dissipate heat effectively. At the same time, the chiller should be avoided being installed in an environment with excessive dust, humidity, or corrosive gases.
