Industrial chillers are not only trusted by chemical, medical, injection molding, electronics and other industries, but are also widely used in ocean-going fisheries for food preservation, refrigeration, quick-freezing, low-temperature processing, ship air conditioning, etc. Marine chillers and ancillary equipment are becoming more and more get people's attention. In particular, the requirements for the compact structure, operation stability, efficient heat exchange and safety protection of marine chillers are constantly increasing.
Marine chiller is a complete refrigeration cycle system. After from evaporator in low-pressure gas compressor, the compressor compressed into a high pressure gas and was into the condenser, the high pressure gas in the condenser cooling water cooling for high pressure liquid, high pressure throttling liquid through the throttle device into a low pressure liquid into the evaporator, low pressure liquid evaporation in the evaporator, low pressure liquid refrigerant in the evaporation of refrigerant water heat at the same time, In order to make low temperature refrigerant water. The vaporized refrigerant gas is sucked up by the compressor for another cycle.
Structure of marine chiller
It consists of compressor, condenser, expansion valve and evaporator, and its functions are as follows:
1.Refrigeration Compressors. A refrigeration compressor is a thermal device that consumes external mechanical work to compress and transport refrigerant in a refrigeration cycle. The refrigeration compressor sucks the low-temperature and low-pressure refrigerant gas from the evaporator and compresses it to make the refrigerant into a high-temperature and high-pressure gas and enter the condenser.
2. Condenser. The condenser is a thermal device that cools the refrigeration vapor discharged from the refrigeration compressor through a cooling medium and transfers heat to a high-temperature heat source. The condenser cools the high temperature and high pressure gas refrigerant from the refrigeration compressor into a low temperature and high pressure refrigerant liquid state.
3. Expansion valve. The expansion valve is a thermal device that throttles and reduces the pressure of the condensed refrigerant liquid. The expansion valve throttles and depressurizes the low-temperature and high-pressure liquid refrigerant into a low-temperature and low-pressure gaseous refrigerant.
4. Evaporator. The evaporator is a thermal device that absorbs heat from the refrigerant to a low-temperature heat source. The low-temperature and low-pressure gaseous refrigerant evaporates in the evaporator and is re-inhaled into the compressor.
Characteristics of Marine chillers
In addition to the function of normal refrigeration compressor unit, the unit also has the following characteristics:
Safe and reliable operation: The machine body is equipped with compressor delay start protector, over-current relay, high and low pressure switch, safety valve, etc., automatic protection and alarm in case of failure, to ensure the safe operation of the unit.
Convenient and flexible movement: The unit is small in size, light in weight, convenient and flexible in disassembly and movement.
Convenient operation: The unit is equipped with a front console, and the control system is equipped with various operation buttons and display devices, which are easy to operate.
The biggest difference between Marine chiller and standard chiller lies in the material of heat exchanger. Because Marine chiller is used in the sea, it needs to have anti-corrosion effect, so the heat exchange tube is all titanium metal.
