Product Specification

JLSK-12HP Water-Cooled Scroll Chiller

Product Description:

Water-cooled scroll chiller is a common refrigeration equipment, mainly used in air conditioning, refrigeration, cooling and other applications in industrial and commercial fields. Its working principle is to realize the cooling effect by compressing the refrigerant.

Specifically, the water-cooled scroll chiller is composed of a compressor, evaporator, condenser, expansion valve, water pump, water tank, control system, etc. The refrigerant is compressed into a high-temperature and high-pressure gas in the compressor, then cooled by the condenser to become a high-pressure liquid, decompressed by the expansion valve, and then becomes a low-pressure liquid, absorbs heat through the evaporator and becomes a low-temperature and low-pressure vapor, and finally is compressed by the compressor again. Compressed into high-temperature and high-pressure gas to form a cycle.

The water-cooled scroll chiller is characterized by the use of a scroll compressor, which has higher energy efficiency than traditional screw and reciprocating compressors, and has the characteristics of high efficiency and energy saving. At the same time, the water-cooled scroll chiller adopts water-cooling method to dissipate heat, which has better heat dissipation effect and lower noise level than air-cooling method.

Production Features:

The advantages of water-cooled scroll chillers are:

1. High efficiency and energy saving: Due to the use of scroll compressors, water-cooled scroll chillers have higher efficiency and lower noise, which can effectively increase refrigeration capacity and reduce energy consumption.

2. Low noise: The working noise of the scroll compressor is lower than that of the traditional screw and centrifugal compressors, which can provide a more comfortable working environment.

3. Environmental protection: The water-cooled scroll chiller does not need to use Freon and other refrigerants that are harmful to the ozone layer, which is more environmentally friendly.

4. Low maintenance cost: Due to the simple structure of the scroll compressor, the maintenance cost is relatively low, and it is also more convenient.

It should be noted that the water-cooled scroll chiller needs to pay attention to factors such as the quality of the water source and the change of the water temperature during use, so as not to affect the cooling effect and the normal operation of the equipment.

Working Principle:

Water-Cooled Scroll Chiller is a cooling device used in refrigeration and air-conditioning systems, and its working principle is as follows:

Compression cycle: The refrigeration cycle of the water-cooled open chiller is realized by a compressor. The compressor sucks in low-temperature and low-pressure refrigerant gas and compresses it into high-temperature and high-pressure gas. Such high-temperature and high-pressure gas is cooled by a heat exchanger to become a high-temperature and high-pressure gas.

Heat exchange cycle: The high temperature and high pressure gas is cooled by water circulation in the heat exchanger. In this way, the refrigerant gas becomes a high-temperature and low-pressure gas.

Expansion cycle: The high-temperature and low-pressure refrigerant gas enters the evaporator through the expansion valve, thereby forming a low-temperature and low-pressure refrigerant gas. In the evaporator, the refrigerant gas absorbs heat from the air, thereby cooling the air.

Cooling cycle: After cooling in the evaporator, the refrigerant gas is drawn again into the compressor, thus starting a new refrigeration cycle.

Water circulation: The water circulation in the water-cooled open chiller is realized through the cooling tower and the cooling water pipeline. The refrigerant gas exchanges heat with the cooling water in the heat exchanger, transfers the heat to the cooling water, and raises the temperature of the cooling water. The cooling water passes through the spray system of the cooling tower to form water mist, which dissipates heat into the air. After the cooling water passes through the cooling tower, it is circulated to the heat exchanger again through the water pump to form a water cycle.

Chiller water pump reversal is usually caused by the following reasons:

1. The phase sequence of the power supply is wrong: If the three-phase wiring sequence of the power supply is wrong, it will cause the motor to run in reverse and cause the water pump to reverse.

2. Control system failure: If the control system of the chiller fails, it may cause the water pump to reverse. For example, if the electrical components in the control system are damaged or poorly connected, it may cause the motor to run in reverse.

3. Mechanical failure of the water pump: If the water pump itself has mechanical failures, such as damaged bearings, loose couplings, etc., it may also cause the water pump to reverse.

If it is found that the water pump of the chiller is reversed, the following measures should be taken immediately to deal with it:

1. Cut off the power supply: Cut off the power supply of the chiller immediately to avoid more damage caused by reverse rotation of the motor.

2. Eliminate the cause of the failure: check the power wiring of the chiller, the control system and the water pump itself, and find out the cause of the reverse rotation of the water pump.

3. Replacement of components: If the electrical components of the chiller are found to be damaged, they should be replaced in time; if the water pump itself has a mechanical failure, it should be repaired or replaced immediately.

4. Test run: After confirming that the fault has been dealt with, conduct a test run to check the normal operation of the chiller to ensure that the pump reverse problem will not occur again.

It should be noted that the reverse of the water pump of the chiller is serious and may cause damage to the equipment, so it should be dealt with and repaired in time. At the same time, the maintenance of the chiller should also be strengthened, and the equipment should be checked and maintained regularly to prevent failures.
