Today, Danfoss is offering a broad programme of industrial products applicable for CO2, however this is dependent on demands regarding the design pressure. The table on page 8 lists the components which are suitable for CO2 applications together with the maximum working pressure limits. For further background information about CO2 as a refrigerant, please refer to the Danfoss article "CO2 Refrigerant for Industrial Refrigeration". General information about CO2 Design pressure There are a number of important factors to be taken into consideration when determining the design pressure. 1. Pressure during operation: The pressure during operation is dependent on actual system design (single stage, cascade system or CO2”brine” system) and the load variation. 2. Pressure during “stand still”: The pressure during stand still can be very high and this has to be taken into consideration: • Asmallseparaterefrigerationsystem can be used to keep the liquid temperature at a level, where the saturated pressure is lower than the design pressure • Designingthesystemwithanexpansion vessel of a size that prevents the pressure from exceeding the design pressure. • Designingtheplantsothatitcan withstand the saturated pressure at the design temperature (approx. 80 bar) Note: In the “IoR - Code of Practice” issued by the Institute of Refrigeration in London, the above mentioned tolerance is stated to be 20% 4. Temperature / pressure requrements for defrosting Depending on the actual design, different ways of defrosting can be applied (natural, water, electrical or CO2 hot gas defrosting). The CO2 hot gas defrosting is the most efficient, especially at low temperatures, but it also has the highest pressure demand. With a design pressure of PS=50-52 bar, it is possible to reach a defrosting temperature of approx. 9-10°C. The saturated pressure at 9°C is 43.9 bar g. By adding 10% for the safety valves and approx. 5% for pressure peaks, the requirement is for pressure PS ~ 50-52 bar g. There is not one common method to perform defrosting. All methods, as described above, are used, depending on the system, but also on the availability of suitable compressors and other components. From Danfoss’ experience, it would appear that the most common solution for industrial refrigeration applications is to use a small separate refrigeration system to limit the temperature of the liquid CO2. 3. Pressure tolerances for safety valves (10 – 15 %) Safety valves require a certain pressure difference (difference between set pressure and reseating pressure) to ensure that the valve is closed properly. Normally the closing tolerance is 10% of the set pressure. Additionally, it is good practice to add 3-5% to the closing tolerance, to take care of any pressure variations / peaks.  Danfoss A/S (RA Marketing/MWA), 08 - 2007 RA0XA502 → DKRCI.PA.000.D1.02 / 520H0243 52008-05-09T08:01:43+02:00http://danfoss.ipapercms.dk/refrigerationandairconditioning/RA/DanfossIndustrialRefrigeration/ComponentsCO2Applications/?Page=6http://danfoss.ipapercms.dk/refrigerationandairconditioning/RA/DanfossIndustrialRefrigeration/ComponentsCO2Applications/?Page=6Application guide Industrial Refrigeration Valves for CO2 Applications Material compatibility CO2 is compatible with almost all common metallic materials, unlike NH3. There are no restrictions from a compatibility point of view, when using copper or brass. The compatibility of CO2 and polymers is much more complex. As CO2 is a very inert and stable substance, the chemical reaction with polymers is not critical. The main concern with CO2 is the physiochemical effects, such as permeation, swelling and the generation of cavities and internal fractures. These effects are connected with the solubility and diffusivity of CO2 in the actual material. Danfoss has carried out a number of tests to ensure that components released for use with CO2 can withstand the impact of CO2 in all aspects. The tests have shown that CO2 is different, and modifications have to be made on some products. The large amount of CO2, which can dissolve in polymers, has to be taken into consideration. Some commonly used polymers are not compatable with CO2, and others require different fixing methods e.g. sealing materials. When the pressure is close to the critical pressure and the temperature is high, the impact on polymers is much more extreme. However, those conditions are not important for industrial refrigeration as pressure and temperatures are lower for these systems. 6 RA0XA502 → DKRCI.PA.000.D1.02 / 520H0243  Danfoss A/S (RA Marketing/MWA), 08 - 20072008-05-09T08:01:43+02:00http://danfoss.ipapercms.dk/refrigerationandairconditioning/RA/DanfossIndustrialRefrigeration/ComponentsCO2Applications/?Page=7http://danfoss.ipapercms.dk/refrigerationandairconditioning/RA/DanfossIndustrialRefrigeration/ComponentsCO2Applications/?Page=7Application guide Industrial Refrigeration Valves for CO2 Applications Water in CO2 systems In NH3 systems it is well known that there are problems as a result of reaction with oil, oxygen, water and solid contaminations, but these are all handled today by frequent oil changes and use of air purgers. Compared to NH3 CO2 is less sensitive, but if water is present, problems may occur. How can water penetrate into a CO2 system? • ThepressureofCO2 systems is always above the atmospheric pressure, therefore there are not the same risks as in e.g. NH3 systems, of air/water penetration into a leaking CO2 system. However, pemeation of water into the system is still possible. • WhenchargingCO2, there are different grades of CO2, some of which allow relatively high amounts of water. • CO2 is a safe refrigerant, and therefore there is a risk, that it is handled without following the normal refrigeration safety requirements. If a system is opened up, air can penetrate into it, and the moisture can condense inside the tubes. If the system is not evacuated properly, some water may well be retained. • Bycharginglubricant(oil)tothecompressor. • Incompletewaterremovalduringinstallation/ commissioning From the reports, it seems that incomplete water removal, due to insufficient vacuum procedure, is one of the main reasons for water contamination in CO2 systems. Vacuum procedures sufficient for ammonia systems are not sufficient for CO2 systems. The acceptable amount of water in CO2 systems is much lower than in systems with other common refrigerants. If the water content exceeds the dew-point, and the temperature is below 0°C, the water will freeze, creating a risk of problems with equipment in the system e.g. blocking control valves. The water can very easily be removed by mounting a drier in the system. Driers in CO2 are very efficient, and are normally mounted in the liquid line to avoid any unnecessary pressure drops being created.

If a safety valve is mounted in a CO2 system at e.g. 52 bar, the pressure in the downstream (outlet) line from the safety valve will pass the triple point at 5.2 bar. Below the triple point, CO2 will change from a mixture of liquid and vapour into a mixture of solid and vapour. The formation of solid CO2 in the downstream line can, in the worst case, block this line. Pressure psi 1450 bar 100 The most effective solution to this problem is to mount the safety valve without an outlet line, thus blowing directly into the atmosphere. The phase change of the CO2 does not take place directly in the valve, but just after the valve, and in this case in the atmosphere. If safety valves or any other safety devices, have to be mounted in liquid lines, they must never blow to the atmosphere or any other places where the backpressure is below 5.2 bar. If the back-pressure is below the triple point (5.2 bar) a very high fraction of the CO2 will be solid. +31°C [87.9°F] 50 bar [725 psi] Liquid 20 bar [290 psi] Vapour Vapour 35 bar [507 psi] 145 10 0% solid CO2 at 50% solid CO2 at the triple point the triple point –56.6°C [–69.9°F] –5.2 bar-a [75.1 psi-a] 3% solid CO2 at the triple point 14.5 1 –78.4°C [–109.1°F] Fig. 5: Flow in downstream lines from safety valves Enthalpy (J) Capacity CO2 capacity calculations for Danfoss Industrial Refrigeration components can be undertaken using the DIRcalc selection software.  Danfoss A/S (RA Marketing/MWA), 08 - 2007 RA0XA502 → DKRCI.PA.000.D1.02 / 520H0243 92008-05-09T08:01:43+02:00http://danfoss.ipapercms.dk/refrigerationandairconditioning/RA/DanfossIndustrialRefrigeration/ComponentsCO2Applications/?Page=10http://danfoss.ipapercms.dk/refrigerationandairconditioning/RA/DanfossIndustrialRefrigeration/ComponentsCO2Applications/?Page=10Application guide Industrial Refrigeration Valves for CO2 Applications Danfoss sub-critical CO2 components Today, Danfoss is offering a broad programme of industrial components applicable for CO2.
