What is the principle of industrial air-cooled chillers

Many industrial productions are inseparable
from the low-temperature production environment provided by the chiller and
cannot obtain efficient production capacity. Therefore, industrial chiller
equipment is a very important refrigeration equipment in the industrial market.
At present, industrial chiller products can be divided into different types,
and their application range is also relatively wide. Let’s talk about the
principle of air-cooled chillers.

 

The air-cooled chiller mainly uses a
cooling fan to dissipate the heat of the built-in cooler with aluminum platinum
fins. The cooler generally adopts an axial flow upward blowing method. Its
advantage depends on the simplicity of the device. It only needs to be
connected to the cold water inlet and outlet, and is suitable for areas with
inconvenient tap water or lack of water sources.

The air-cooled chiller is one of the
chiller models. It uses the compressor of the chiller to cool the water at room
temperature to a certain temperature to enhance the cooling of the mold or
machine. It is an independent machine, and the radiator is a built-in fan.
There are mainly three interconnected systems: refrigerant circulation system,
water circulation system, and electrical automatic control system.

Refrigerant circulation system:

The liquid refrigerant in the evaporator
absorbs heat from the water and starts to evaporate. Eventually a certain
temperature difference will be formed between the refrigerant and the water.
The liquid refrigerant also evaporates completely into a gaseous state, and
then is sucked and compressed by the compressor (pressure and temperature
increase). The gaseous refrigerant releases heat through the condenser and
condenses into a liquid. After throttling by the expansion valve (or cooling water
pipe), it becomes a low-temperature and low-pressure refrigerant, enters the
evaporator, and completes the refrigerant cycle process.

Water circulatory system:

The water pump is responsible for pumping
the water in the water tank to the equipment that needs to be cooled by the
user. The chilled water will take away heat and increase its temperature before
returning to the chilled water tank.

Water-cooled chillers mainly use water to
dissipate heat from the shell and tube cooler. A closed cooling tower needs to
be installed. Contrary to air-cooled chillers. Water-cooled chillers do not
require cooling fans and have superior energy consumption. The chiller uses
water to dissipate heat from the heat pipe, and the heat exchange efficiency is
higher than that of the air-cooled chiller.

Our LNEYA air-cooled chillers have the
following characteristics:

1. Easy to install, easy to operate,
suitable for cooling of various factory equipment.

2. Low noise water pump, compressor motor,
good cooling and condensation effect, stable throttling mechanism, and
excellent anti-rust treatment.

3. Adopt high-performance compressor
imported from Europe and America, with high EER value, low noise and stable
operation

4. LCD control panel, equipped with
precision electric temperature controller, can run smoothly for a long time.

5. Using high-efficiency heat transfer heat
exchanger, the loss of cold capacity is small, the oil return is easy, and the
heat transfer tube does not freeze and crack.

6. The structure is highly optimized, and
the heat exchange plate is used to support the body. The structure is simple,
compact and practical.

7. Multi-level or stepless capacity control
to accurately coordinate load changes.
