Brazed Plate Heat Exchanger for CO Applications

CO2 (R744) Due to global warming, climate change phenomenon, and rising restriction on the use of high GWP synthetic refrigerant; replacing HCFC and HFC by natural refrigerants has gained importance. HVAC system manufacturers are using natural refrigerant instead of HCFC and HFC in their latest products, in order to take a part in slowing global warming. The environment-friendly CO2 HVAC is growing in the vehicle air conditioning systems, heat pumps HVAC and house heating markets. Hydrocarbon refrigerants are usually composed of flammable substances with high potential risk. In contrary CO2 (R744)...

Super High Pressure BPHE KAORI C series is specially designed for R744 (CO2), in supercritical, transcritical and subcritical system applications, can be used as gas cooler, condenser, evaporator ,economizer, cascade, heat recovery, SLHE (suction line heat exchanger), and intercooler of heat pump in refrigeration, and supercritical extraction industries. Designed with different maximum working pressure resistance, at 70 bar, 100 bar and 140 bar, available for various duties and different performance specifications, with compact size, outstanding heat transfer efficiency and low pressure drop are the...

CO2 Refrigeration System Subcritical Cascade system Cascade refrigeration system is a good solution for low-temperature refrigeration system that can not be achieved by single-stage refrigeration systems, enabling optimum compressor efficiency, and reduce compressor exhaust temperature and its compression ratio. In the cascade refrigeration system, the system of HFC refrigerant is applied to the main circuit (mid-high temperature), and R744 (CO2) refrigeration system is applied to the low temperature overlay circuit, two individual circuits exchange heat through a cascade heat exchanger. Furthermore,...

Subcritical Secondary Coolant System Usually, secondary coolant system uses brine circulation system as the refrigeration medium, but through the high density characteristic of liquid CO2, and its better thermodynamic property during medium temperature refrigeration process, R744 (CO2) is very suitable for replacing the original E.G, P.G secondary refrigerant. This refrigeration system first works with HFC refrigerant compressor to start cooling process, and through evaporator, it cools down (condense) R744 (CO2) on the secondary side, then a pump will distribute low temperature R744 (CO2) through...

Transcritical CO2 Heat Pump System CO2 heating system, as known as CO2 heat pump system, could be divided into two categories, air and water source heat pump. Both has mainly the same concept, but different heat sources. Air source heat pump is very suitable in the frigid zones, with high COP (Coefficient of performance) efficiency for hot consumption water or bath water applications. KAORI C series plate heat exchanger could be used as the gas-cooler in heat pump system, in this system, water could be heated up to maximum 90°C, at this temperature, it is also suitable for cleaning and other industrial...

Supercritical CO2 Extraction The extraction technology in food and pharmaceutical industries are commonly using organic solvent as the extraction agent. But in recent years, many advanced technologies have begun to replace organic solvent with supercritical R744, due to the higher solubility and higher permeability, R744 critical temperature is closer to the ambient temperature (31.7°C), and rare chemical reaction with the extraction substances. With all the above mentioned advantages, supercritical CO2 is one of the most important developments in many industries and countries. KAORI latest high...
