There are two types of refrigerators: water-cooled and air-cooled

Water cooled refrigeration has a good effect, but requires cooling water. Air cooled refrigeration is flexible and convenient, without the need for cooling water, and is suitable for use in areas with water scarcity or in mobile situations.

1. The air-cooled chiller contains an insulated water tank and water pump inside its body, eliminating the need for additional cooling towers to dissipate heat. It is very convenient to install and move. However, it has high requirements for the working environment. Firstly, because it is cooled by a hot air cycle, if the ventilation effect in the installation workshop is not good, it will directly affect the cooling effect of the chiller.

2. Cold water chillers are energy-saving machines that achieve cooling effects through steam compression or absorption circulation. Refrigeration units are divided into air-cooled refrigeration units and water-cooled refrigeration units. The air-cooled refrigeration unit contains a water tank and a water pump, without the need for cooling tower heat dissipation. It is easy to install and move, but has high environmental requirements, Because it is cooled by a hot air cycle, water-cooled refrigeration units require additional cooling towers and water pumps.

Water tank cooling machineConfiguration Introduction:

The compressor of the Hu Xin chiller refrigeration unit adopts the original imported grain wheel compressor, which has extremely low single machine failure and ensures high stability of the chiller performance. The unit also uses multiple compressors in parallel, and each compressor of the refrigeration unit comes with an independent refrigeration circuit, namely the evaporator and condenser, which are completely independent. All compressors are commanded by a unified microcomputer control system, and are turned on and off one by one, without mutual interference, When it is necessary to maintain the phone, the compressors can be cut off one by one for maintenance, and other circuits can still be used. Therefore, when the cooling capacity is sufficient, there is no need to purchase a backup chiller

Water tank cooling machineWorking principle of;

During the operation of the Hu Xin chiller refrigeration unit, the low-temperature and low-pressure liquid refrigerant exchanges heat with the surrounding water in the evaporator, absorbing heat from the water and turning it into chilled water. At the same time, the refrigerant is converted into a gaseous state, which is absorbed by the compressor and compressed into a high-temperature and high-pressure liquid refrigerant. Then, it enters the condenser and exchanges heat with the indoor medium in the condenser, Part of the heat of the refrigerant is absorbed by the medium, and the temperature of the medium rises. The refrigerant releases heat inside the condenser and is converted into a high-temperature and high-pressure liquid, which then enters the expansion valve for throttling. Throttling is a rapid cooling process. The refrigerant is converted into a low-temperature and low-pressure liquid, and then enters the evaporator for heat exchange and evaporation, reciprocating circulation, and thus achieving the entire process of the refrigeration system

Low temperature chilled water box type chiller Industrial chiller is an efficient and energy-saving refrigeration equipment. The unit provides constant temperature chilled water of -120 ℃ -30 ℃, which is transported by a circulating pump to the equipment or product that needs cooling for cooling treatment to meet the needs of the production process and promote normal production.

Refrigerators are all composed of five major components in series: a compressor, a condenser, an evaporator, a drying filter, and an expansion throttle valve. An appropriate amount of refrigerant is injected into them, and the electrical appliances control the operation of the compressor according to environmental requirements to achieve the purpose of refrigeration and heat transfer [4].

compressor

A driven fluid machine that elevates low-pressure gas to high pressure. It is the heart of the refrigeration system. It sucks in low-temperature and low-pressure refrigerant gas from the suction pipe, drives the piston to compress it through the operation of the motor, and exhausts high-temperature and high-pressure refrigerant gas to the exhaust pipe, providing power for the refrigeration cycle, thus achieving a refrigeration cycle of compression, condensation, expansion, and evaporation (heat absorption).

condenser

The high-temperature and high-pressure refrigerant vapor discharged from the compressor is condensed into liquid refrigerant through heat dissipation. The heat absorbed by the refrigerant from the evaporator is absorbed by the medium (atmosphere) surrounding the condenser

evaporator

The liquid refrigerant is converted into a gaseous state here.

Drying filter

In the refrigeration system, the function of the drying filter is to absorb moisture from the refrigeration system, block impurities from passing through the system, and prevent ice and dirt blockage in the refrigeration system pipelines. Due to the fact that the most easily blocked part of the system is the capillary (or expansion valve), drying filters are usually installed between the condenser and the capillary (or expansion valve).

expansion device

Throttling and depressurizing the high-pressure liquid refrigerant from the liquid storage dryer, adjusting and controlling the liquid refrigeration dosage entering the evaporator to adapt to changes in refrigeration load, while preventing liquid hammer phenomenon in the compressor and abnormal overheating of the evaporator outlet steam.

Water tank cooling machine Air cooled low-temperature chiller/Water cooled low-temperature freezer/Low temperature ice water machineComposition and schematic diagram

Composition of chiller unit: composed of refrigeration unit system, refrigerant circulation system, water circulation system, electrical automatic control protection system, heat exchanger, chilled water pump, water tank (configured according to customer needs), automatic water replenishment float valve, water flow switch and other components

operational principle

The unit utilizes the principle of heat exchange to reduce the temperature of chilled water to the required temperature (normal ≥ 5 ℃, low temperature ≥ -20 ℃) through a heat exchanger. The water is pumped into the evaporator water tank through a chilled water pump for heat exchange, generating chilled water, which is then sucked into the evaporator water tank by the water pump for circulation. When the chilled water is insufficient, the chilled water flow cannot push the water flow switch blades, and the chiller stops running. At this time, the automatic water replenishment device starts to work to replenish water. The water level in the water tank can be determined through the liquid level display, and the chiller can be restarted.

Refrigerant circulation system

The liquid refrigerant in the evaporator absorbs heat from the water and begins to evaporate. Finally, a certain temperature difference is formed between the refrigerant and the water. The liquid refrigerant also completely evaporates into a gaseous state, which is then sucked in and compressed by the compressor (with increased pressure and temperature). The gaseous refrigerant absorbs heat through the condenser (air cooled/water cooled) and condenses into a liquid. After being throttled by an expansion valve (or capillary), it becomes a low-temperature and low-pressure refrigerant and enters the evaporator, completing the refrigerant circulation process.

Electrical control system

Including power supply and automatic control. The power supply part supplies power to compressors, fans, water pumps, etc. through contactors. The automatic control part includes a temperature controller, pressure protection, delay device, relay, overload protection, etc., which are combined to achieve automatic start stop and protection functions based on water temperature.
