Water-cooled chillers are refrigeration equipment that dissipates heat through water circulation and are widely used in industrial cooling, commercial air conditioning, medical equipment, etc. Its core principle is to transfer heat to cooling water through the combination of refrigerant circulation system and water cooling system, and then discharge it through cooling tower or external water source.
Working principle
Refrigeration cycle: The refrigerant circulates between the compressor, condenser, expansion valve, and evaporator to absorb and release heat.
Water circulation heat dissipation: After the cooling water absorbs the heat of the condenser, it dissipates heat through the cooling tower or external water source (such as river water) and then circulates back to the condenser.
Water-cooled water chiller is a kind of air-conditioning and refrigeration equipment, which has the following characteristics:
1.High efficiency and energy saving: The water-cooled chiller adopts high-efficiency compressors and heat exchangers, which has high refrigeration efficiency and energy utilization rate, and can save energy costs.
2.Good stability: The water-cooled chiller adopts a water-cooled circulation system, which can operate at a constant temperature and pressure, and has good stability.
3.Low noise: The compressor and fan of the water-cooled chiller are usually located outdoors, which reduces indoor noise.
4.Easy installation: The installation of the water-cooled chiller is relatively simple, only need to connect the chiller and the water circulation system.
5.Wide range of applications: Water-cooled chillers are suitable for large buildings, industrial production lines and equipment that require a lot of cooling.
6.Good cooling effect: The cooling effect of water-cooled chillers is usually better than that of air-cooled chillers, because water cooling is more efficient than air cooling.
7.Strong durability: The water-cooled chiller adopts high-quality materials and components, has high durability and reliability, and can run stably for a long time.
8.Automatic control: Water-cooled chillers usually have an automatic control system, which can realize remote monitoring and control, improving the reliability and operability of the equipment.
In short, the water-cooled chiller has the characteristics of high efficiency and energy saving, good stability, low noise, convenient installation, wide application range, good cooling effect, strong durability, and automatic control. It is an important type of refrigeration equipment.
The working principle of the water-cooled chiller is to use the physical changes of the refrigerant in the refrigeration cycle to achieve the cooling effect. The specific process is as follows:
1.Compression process: The compressor in the water-cooled chiller sucks in low-temperature and low-pressure refrigerant gas, and compresses it into high-temperature and high-pressure gas through compression.
2.Condensation process: The high-temperature and high-pressure gas dissipates heat through the condenser and becomes a high-temperature and high-pressure liquid.
3.Expansion process: The high-temperature and high-pressure liquid enters the evaporator through the expansion valve. Due to the throttling effect of the expansion valve, the pressure and temperature of the liquid refrigerant decrease rapidly, thus turning into a low-temperature and low-pressure refrigerant vapor.
4.Evaporation process: The low-temperature and low-pressure refrigerant vapor exchanges heat with the cold water in the evaporator, thereby reducing the temperature of the cold water.
5.Circulation process: cold water circulates through the pipes and continuously absorbs the refrigerant vapor in the evaporator to achieve cooling effect. At the same time, the refrigerant vapor returns to the compressor after absorbing the heat of the cold water, forming a reciprocating refrigeration process.
In short, the working principle of the water-cooled chiller is to use the physical changes of the refrigerant in the refrigeration cycle to achieve the cooling effect. Through the processes of compression, condensation, expansion and evaporation, the refrigerant is recycled to continuously absorb and release heat, thus Realize the cooling of cold water.

The cooling efficiency and power consumption of a water-cooled chiller depends on many factors, including the type of refrigerant, ambient temperature, load changes, equipment quality, etc.
Generally speaking, the higher the cooling efficiency of the water-cooled chiller, the lower the power consumption. Commonly used refrigerants include R22, R134a, R410a, etc. Among them, R410a has higher cooling efficiency and can achieve higher cooling capacity with lower power consumption. The ambient temperature and humidity will also affect the cooling efficiency and power consumption of the water-cooled chiller. Generally speaking, the lower the ambient temperature, the higher the cooling efficiency and the lower the power consumption. Load changes will also affect the cooling efficiency and power consumption of the water-cooled chiller. Frequent load changes will reduce the cooling efficiency of the water-cooled chiller and increase the power consumption of the equipment.
In addition, equipment quality is also an important factor affecting the cooling efficiency and power consumption of water-cooled chillers. High-quality equipment usually achieves higher cooling efficiency and lower power consumption, and also has a longer service life and less energy consumption. Maintenance costs.
In short, the refrigeration efficiency and power consumption of water-cooled chillers depend on many factors. It is necessary to select the appropriate model and specification according to the actual needs and the use environment. At the same time, select high-quality equipment and refrigerants, and perform regular maintenance to improve The cooling efficiency of the equipment and reduce energy consumption.
