Recent technologies used in refrigeration system

Here in this article, we are going to discuss the recent technologies which are being used in the field of refrigeration system and absolutely enhance the world of refrigeration.

1. Active augmentation technology

It improves the expansion capacity and energy efficiency of vapor pressure systems. Murthy et al.1 has conducted a comprehensive review of the use of various extension systems such as a rotating piston, rolling piston, rotary vane, scroll, screw and turbine and their reported performance. They noted that critical CO2 reported 30% COP while non-CO2 systems registered their COP as 10%. -CO2. In addition it is understandable that renewable energy efficiency is an encouraging practice for refrigeration systems. Research on topics such as non-reversal, heat transfer, expansion process, internal leakage etc. still open.

2. Squeeze the technology

It plays an important role in the liquefaction cycle of cryogenic processes. Lei et al.2 showed that cascade extensions can influence the thermal properties of hot and cold currents in heat transfer to cryogenic systems. Depending on the pinch technology, an integrated series series expander has been developed. Pinch technology makes provision to analyze a variety of systems for large cryogenic systems. The temperature changer and expander in this refrigerator expansion system is included in the series. The heat transfer efficiency has been found to be high in cryogenic ISE systems, the use of compression technology compared to conventional traditional methods can save up to 30% to 50% energy.

3. Absorption technology in the refrigerator

It was studied and methods to improve performance were evaluated by Wu et al.3. In this case, bubble cooling systems and bubble absorbers are used. Behavioral characteristics of the bubble were identified and described in diagram. The current pairs of suction refrigerators in the suction bubbles described, this time contained fifty liquids. This research is useful for people doing research in the technical aspects of a vacuum cleaner. Performance enhancement can be achieved in three different types of methods such as mechanical-physical, chemical method and adscititious contactless forces. Ultrasonic field and magnetic field are tested in the form of adhesititious contactless power. Touch and confidence are discussed to show the impact of the development. The current and potential fluids have been carefully analyzed.

4. Grid operating technology outside the grid

It is because food storage is the most neglected in India due to insufficient access to different types of energy. Aste et al. 4 has done extensive research in the literature review and scientific technology in this case. The main goal is to achieve the conservation of a variety of foods and the next to focus on technical, economic and social vision. In areas without electricity grids food storage is done with a functional / free-standing refrigerator that is available using electricity. In commercial situations, refrigerator technology that works off the grid is encouraged. Freezing systems have been established to define relevant information.

5. Biomethane liquification technology

other refrigeration technology that is gaining importance in recent days. It demonstrated comparatively cost-effective analysis and technology of other refrigeration technologies for the development of liquified biomethane, a biofuel also called liquified bio LNG. These are designed to design biogas plants incorporated under the biogas development step so that the biomethane is available in liquid form at a temperature of 152 0C AND 2 pressure bars. Five types of techniques have been considered in this regard, starting with liquid nitrogen vaporization (benchmark); reverse the Rankine cycle with a mixed refrigerator; reverse Brayton cycle; Claude’s cycle; reverse Stirling cycle. The use of mixed refrigerators has been the best decision taken in the Rankine cycle. Primary power consumption is between 14% and 20%.

6. Backup compressed refrigeration system

It modeled and analyzed by Rodriguez. They describe the power control and efficiency of the thermal energy storage system (TES) for the vapor pressure center in terms of phase switches (PCM) .The unique system of PC-based TES tank and its current connection to the refrigerator. the system is designed. In this case the integrated dynamic model is tested by looking at the various time frames associated with the connected system. Different types of operating techniques have been described depending on the deliberate use of the TES tank as a low-temperature power supply to separate the cooling and production desire, assuming a stable factor and energy limitations. Cooling power barriers were analyzed in detail in this operation and the power monitoring controller was resolved.

7. Nanotechnology refrigerator

introduced remembering energy consumption and environmental concerns, this technology improves the thermal performance of the refrigeration system. This can be done by changing the properties of the active liquid or by using different systems. Nowadays nanofluids have become very popular because of their outstanding thermophysical properties that can be comfortably treated in refrigerators and air conditioning systems. Many future studies are needed to improve their facilities. Low boiling nanofluids need to be made. These days industries are showing great interest in natural refrigerators remembering the pollution they cause. Nanofluids surface tension and dielectric properties require further study. Different types of water-based water are used as a second refrigerator but no research has been done on these water-based nanofluids.
