A low temperature chiller system is a type of refrigeration equipment that is mainly used in industrial, commercial and residential areas to provide low-temperature cooling water for various purposes. This type of equipment has a wide range of applications in chemical, pharmaceutical, food processing, biotechnology, electronics manufacturing and other industries.

Low temperature chiller system

Single-stage refrigeration cycle system

Single-stage low temperature chiller system is a type of refrigerator that is widely used. It can be used in ice making, air conditioning, food refrigeration and industrial production processes. The single-stage refrigeration cycle means that the refrigerant undergoes four processes of compression, condensation, throttling, and evaporation in the refrigeration system, and then the cycle of the single-stage refrigerator is completed, that is, the purpose of refrigeration is achieved. The refrigeration system consists of an evaporator, a single-stage compressor, an oil separator, a condenser, an ammonia storage tank, an ammonia liquid separator, a throttle valve and other ancillary equipment, which are connected to each other through pipes to form a closed system. Among them, the evaporator is a device that transports cold energy. After the liquid refrigerant evaporates, it absorbs the heat of the object being cooled to achieve refrigeration; the compressor is the heart of the system, playing the role of inhaling, compressing, and transporting the refrigerant vapor; the oil separator is used for settling Separates the oil in the compressed refrigerant vapor; the condenser condenses the high-temperature refrigerant vapor discharged from the compressor into a saturated liquid; the ammonia storage is used to store the condensed refrigerant ammonia liquid in the condenser and adjust the relationship between the condenser and the evaporator The supply and demand relationship of refrigerant ammonia liquid; the ammonia liquid separator is an important accessory equipment in the ammonia gravity liquid supply system; the throttle valve plays a role in throttling and depressurizing the refrigerant while controlling and regulating the flow of refrigerant liquid into the evaporator. And the system is divided into two parts: high pressure side and low pressure side.

Two-stage refrigeration cycle system

The two-stage refrigeration cycle is developed on the basis of the single-stage refrigeration cycle. The compression process is carried out in two stages. The refrigerant vapor from the evaporator first enters the low-pressure stage cylinder and is compressed to an intermediate pressure. After intermediate cooling, it enters the high-pressure stage. stage cylinder, compressed to condensing pressure and enters the condenser. Generally, when the evaporation temperature is between -25℃ ~ -50℃, a two-stage compressor should be used for refrigeration. The refrigeration system consists of an evaporator, a two-stage compressor, an oil separator, a condenser, an intercooler, an ammonia storage tank, an ammonia liquid separator, a throttle valve and other ancillary equipment, which are connected to each other through pipes to form a closed system. . Among them, the intercooler uses a small amount of liquid refrigerant to vaporize and absorb heat under the intermediate pressure, so that the superheated steam discharged from the low-pressure stage is cooled, and the suction temperature of the high-pressure stage is reduced. At the same time, the high-pressure liquid refrigerant is cooled.

How does low temperature chiller system works?

The working principle of the low temperature chiller system is based on the circulation of refrigerant. The refrigerant circulates in the system and completes the four processes of compression, condensation, expansion and evaporation through the compressor, condenser, expansion valve and evaporator. During the entire process, the refrigerant continuously absorbs and releases heat to achieve the preparation and supply of cold water.

The refrigerant is compressed in the compressor, increasing its temperature and pressure.

The high-temperature and high-pressure refrigerant enters the condenser and exchanges heat with the cooling water. The heat is taken away by the cooling water and the refrigerant condenses into a liquid.

The liquid refrigerant passes through the expansion valve and the pressure decreases, forming a low-temperature and low-pressure liquid-gas mixture.

The low-temperature and low-pressure refrigerant enters the evaporator, absorbs the heat of the cooling water, and evaporates into gas. The cooling water releases heat during this process and lowers its temperature.

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

Components of low temperature chiller system

Compressor: Responsible for compressing the refrigerant and increasing its temperature and pressure.

Condenser: used for heat exchange between refrigerant and cooling water to condense the refrigerant into liquid.

Expansion valve: Responsible for reducing the pressure of the refrigerant to form a low-temperature and low-pressure liquid-gas mixture.

Evaporator: used for the refrigerant to absorb the heat of the cooling water to prepare cold water.

Control system: including temperature sensors, pressure sensors, liquid level gauges, etc., responsible for monitoring and adjusting the operating status of the entire system.
