R-11 is assigned an ozone depletion potential of 1.0, and U.S. production was ended on January 1, 1996. Prior to the knowledge of the ozone depletion potential of chlorine in refrigerants and other possible harmful effects on the environment, trichlorofluoromethane was sometimes used as a cleaning/rinsing agent for low-pressure systems.[4] Trichlorofluoromethane was formerly used in the drinking bird novelty, largely because it has a boiling point of 23.77℃ (74.79℉). The replacement, dichloromethane, boiling point 39.6℃ (103.3℉), requires a higher ambient temperature to work. The substance was included in the production moratorium agreed in the Montreal Protocol of 1987. However, in 2018, its atmospheric concentration was noted to be declining more slowly than expected,[5] and it subsequently emerged that it remains in widespread use as a blowing agent for polyurethane foam insulation in the construction industry of China.[6] ...

Refrigerant gas supplier. R-22 is gas is used in a variety of maritime refrigeration applications for low, medium and high temperatures (-40 to +16° C). This colorless gas is better known as HCFC-22, or R-22. It is commonly used as a propellant and refrigerant. R22 refrigerant is one of the most commonly used refrigerants.
Protocols and regulations such as the Montreal Protocol (1987), the Kyoto Protocol (1997), the European F-gas regulation (2006) and now its revision (2014) cause a shift toward refrigerants with both zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP). Alternative refrigerants with low-GWP are under investigation for residential heat pumps and air-conditioners as R-410A has a GWP of 2088. In this study, two promising alternative refrigerants with a low-GWP, DR-5A (R-454B) and L41-2 (R-447A), both HFC-HFO mixtures with a GWP of 466 and 583 respectively, have been tested in a residential heat pump. Â To assess and to compare the heat pump performances using R-410A, DR-5A and L41-2, drop-in tests have been carried out in a 10 kW air-to-water reversible heat pump. For each refrigerant, the heat pump performances have been assessed for 2 rating conditions and 2 operating limit conditions in the cooling mode and for 6 rating conditions and 3 operating limit conditions in the heating

Among alternative refrigerants, ammonia with zero Ozone Depleting Potential (ODP) and Global Warming Potential (GWP), and favorable thermodynamic properties is a sensible choice as a replacement for the synthetic refrigerants, which are powerful greenhouse gases.. In this paper, the results of experiments done on a new ammonia water-to-water heat pump prototype at different evaporation temperatures and compressor speeds are reported. The heat pump is designed to deliver 7 kW heat at evaporation temperature of -5°C and condensation temperature of 40°C. The hot discharge gas from compressor is utilized to provide sanitary hot water, and the rest of the heat is used for preheating the tap water and space heating of a single-family house. The compact design of the heat pump helps reducing the refrigerant charge. To reduce the charge further and to prevent oil accumulation at the bottom of evaporator, a minichannel aluminum heat exchanger is used as evaporator.. ...
A method and apparatus for using a secondary refrigerant to precool and liquefy a primary refrigerant, then vaporizing and expanding the primary refrigerant to cool a cold tip of a cryosurgical instrument for ablation of biological tissue, such as cardiovascular tissue, in particular endocardiac tissue and tissue inside a cardiac blood vessel. The secondary refrigerant has a critical temperature above the critical temperature of the primary refrigerant, and a cooling temperature below the critical temperature of the primary refrigerant, thereby facilitating the use of the precooling step to provide liquid primary refrigerant in an operating room environment in which the primary refrigerant could not otherwise be provided in the liquid phase.
A method and apparatus for determining the sufficiency of refrigerant charge in an air conditioning system by the use of only two temperature measurements. The temperature of the liquid refrigerant leaving the condenser coil is sensed and the temperature of the condenser coil itself is sensed and the difference between these two measurements is calculated to provide an indication of the adequacy of refrigerant charge in the system. This process is refined by steps taken to eliminate measurements during transient operations and by filtering signals to eliminate undesirable noise. A permitted threshold of deviation is calculated by using probability theory.

0071]Secondly, in the arrangement shown in FIG. 3, some of the cooling duty required for the first refrigerant is shifted from the third refrigerant stream 120 (passing through the first cooling stage 38), and passed to one or more cooler(s) represented in FIG. 3 by cooler 54. This reduces or `unloads` some of the cooling power or duty hitherto required of the third refrigerant stream 120 (to provide the same level or amount of condensed first refrigerant as conventionally provided), enabling the same cooling power of third refrigerant stream 120 to provide more cooling to the first refrigerant stream and/or to the hydrocarbon stream 10. Thus, the first refrigerant stream 20 either has more cooling power for the second cooling stage 12, which is usually the main cooling stage of a liquefaction plant, and/or the cooled hydrocarbon stream 10a is already cooler prior to entry in the second cooling stage 12 ...

In consideration of physical and chemical properties of pure substances, speed of sound is one of important quantity which can used to calculate many of other thermo-physical properties such as isothermal compressibility, Joule-Thomson coefficient, isobaric heat capacity and etc. These thermo-physical properties are the main parameters in industrial and chemical processes. Development of accurate models for thermodynamic properties computation such as speed of sound is well expected above all in those fields where very high performance calculations have to be reached. In this present work, a new generalized model as a function of reduced temperature and reduced density is proposed to correlate speed of sound of methane, ethane, propane and butane halogenated refrigerants. Speed of sounds have been calculated and compared with data reported in literatures for 5600 data points of 28 refrigerants, and the overall average absolute percentage deviation of 0.92%. The source of speed of sound data used in this

As discussed in chapter 3.4, compressor performance depends on the evaporating and condensing pressures. The saturation pressure of the evaporator determines the density of the refrigerant gas at the inlet of the compressor, thus affecting the refrigerant mass flow per compressor revolution. The total pressure difference between the evaporating and condensing sides also affects the required compressor power consumption.. The evaporator and condenser affect these pressure levels though their ability to transfer energy between the refrigerant and the secondary fluids. The evaporator operating point is the equilibrium point at which the performance of the evaporator matches the performance of the compressor. The refrigerant mass flow is determined by the compressor, and at the operating point the refrigerant is evaporated at a stable saturation temperature.. The compressor curve in Figure 6.24 has a positive slope, indicating that the available cooling capacity increases with higher evaporation ...
A catheter has an inner sleeve through which refrigerant circulates to and from a source of refrigerant. The catheter also has an outer sleeve surrounding the inner sleeve, including a distal end thereof. The outer sleeve is filled with a frozen biocompatible substance. The refrigerant is separated from the biocompatible substance by one or more walls of the inner sleeve such that the refrigerant is isolated from a patient in whom the catheter is positioned by both the inner sleeve and the frozen biocompatible substance. The refrigerant circulates through the catheter when the catheter is positioned in the patient to maintain the biocompatible substance frozen as heat is transferred from the patient to the biocompatible substance.

Water-natural, non toxic, low cost, environmentally friendly, and widely available-is widely used in water cooling, and if evaporated in the process may be called a "refrigerant". Water also commonly serves as a heat transfer and storage material ,and in large systems it may actually fill all of these roles.. The simplest and lowest cost open-cycle cooling systems, known as swamp coolers in the south-west United States, do not even need power for a compressor, merely a blower fan, so humidified cooled air is simply vented into the living space. Portable free-standing units can be obtained at discount stores for less than $200. However, if these systems are improperly implemented the drawbacks are multiple and severe.. The total cooling power of the unit is limited by the fact that neither coolant nor air can be recirculated. If the cooling unit does not have a supply of fresh dry air and the waste air is not effectively vented, stagnant humid air will make the space more uncomfortable than if it ...
In an ejector cycle system, high-pressure side refrigerant is decompressed by an ejector in cooling operation for cooling a compartment, and is decompressed by a fixed restrictor in heating operation for heating the compartment. Therefore, in the heating operation, the pressure of refrigerant to be sucked into a compressor can be made lower, and the temperature of refrigerant discharged from the compressor is increased. Alternatively, in the cooling operation, a flow direction of refrigerant flowing through at least one of an exterior heat exchanger and an interior heat exchanger is identical to that in the heating operation.
