Refrigeration effect of water-cooled chiller at -15℃

The main configurations of water-cooled
chillers are: compressors, electrical components, water pumps, evaporators,
condensers, high/low pressure controllers, high/low pressure gauges, LCD
thermostats, expansion valves, antifreeze switches, hand valves , Fan. Screw
chillers and high-precision constant temperature circulating chillers are
trusted by well-known international and domestic vacuum instruments, analytical
instruments, and other manufacturers.

Water circulation system of water-cooled
chiller:

First inject a certain amount of water into
the water tank of the chiller, cool the water through the chiller refrigeration
system, and then send the low-temperature cooling water to the equipment that
needs to be cooled by the water pump. The chilled water will take away the heat
and increase the temperature before returning to The water tank achieves the
cooling effect. The cooling water temperature can be automatically adjusted
according to requirements, and long-term use can save water. Therefore, the chiller
is a standard environmentally friendly and energy-saving equipment.

Refrigerant circulation system of
water-cooled chiller:

The liquid refrigerant in the evaporator
absorbs the heat in the water and starts to evaporate. Eventually, a certain
temperature difference is formed between the refrigerant and the water. The
liquid refrigerant is also completely evaporated and becomes a gaseous state,
which is sucked by the compressor and compressed (pressure and temperature
increase) , The gaseous refrigerant absorbs heat through the condenser
(air-cooled/water-cooled), condenses into a liquid, and is throttled by a
thermal expansion valve (or capillary tube) to become a low-temperature and
low-pressure refrigerant to enter the evaporator, completing the refrigerant
cycle process.

Features of water-cooled chillers

1. Fully enclosed refrigeration system,
stable work and reliable performance;

2. Digital display and control, high
temperature control accuracy and uniform temperature;

3. Using ultra-quiet circulating water
pump, the whole machine works quietly and has low noise;

4. High-performance refrigeration system
and pump circulation system, suitable for long-term continuous work;

5. Closed water tank and pipeline structure
to avoid coolant pollution and oxidation;

6. Standard stainless steel water inlet and
outlet ports, can be equipped with a variety of joints or hoses, external
closed loop;

7. Real-time display of working status and
alarm status;

8. Microcomputer temperature controller,
temperature digital display, adjustment unit 0.1 degrees Celsius, temperature
range 5~50 adjustable

9. The role of the mechanical industrial
equipment of the chiller: control the pressure oil temperature of the oil
pressure system, stabilize the oil temperature and oil pressure, extend the oil
quality use time, improve the efficiency of mechanical lubrication, and reduce
wear.

Multiple protections for water-cooled
chillers: 1. Over-temperature protection; 2. Current protection; 3.
Self-diagnosis; 4. Intelligent antifreeze; 5. Water flow alarm; 6. Water level
alarm; 7. Pressure alarm; 8. Time switch machine
