Heat Recovery System in Domestic RefrigeratorIjrdt Journal
Refrigeration is a process in which work is done to move heat from one location to another. Refrigeration technology has rapidly evolved in last century from ice harvesting to temperature controlled rail cars. Most widely used current application of refrigeration is for air-conditioning of homes and public buildings. During refrigeration, heat from the refrigerant is dissipated for the successful completion of a refrigeration cycle. In normal household refrigerators, the heat from the refrigerant is removed using a condenser where the refrigerant cools and the air surrounding the condenser heats up. The strategy of how to recover the dissipated heat to develop a waste heat recovery system is relevant. The energy lost in waste heat cannot be fully recovered. However, much of the heat can be recovered and the loss can be minimized by adopting different measures. Hot air can be used for space heating, industrial drying, preheating aspirated air for oil burners, or any other application requiring warm air. The purpose of this project is to demonstrate the technical feasibility of a heat recovery system to recover waste heat from the condenser in the refrigerator and to reuse it for heating application.

Performance Test on Mixed Refrigerant in Domestic RefrigeratorIJERA Editor
Refrigerator is a household appliance used to preserve the foods, vegetables, beverages at low temperature. Refrigerant is the blood of the refrigerator and it changes its phase to transfer heat for giving cooling effect inside the refrigerator. Generally many refrigerator works under the vapour compression cycle and it uses only one refrigerant. Each and every refrigerant used in the refrigerator must have disadvantages, to overcome this problem we use mixed refrigerant (two different refrigerants with different properties are mixed together). In this project combination of R600a (isobutane) and R134a (1, 1, 1, 2-tetrafluroethane) is selected as a mixed refrigerant. R600a have some good properties like zero ODP, zero GWP and high latent heat of vapourization and R134a is non-toxic, non-flammable, non-corrosive and zero ODP.

Air Cooled condensers were first introduced in US
power industry in early 1970’s, but only during last 10-15
years number of installations greatly increased largely due to
growing attention being paid to environmental safety. Also,
growing demand for water for both domestic and industrial

condensers. This is a review paper which studies the
performance of Air-cooled condenser under various operating
conditions it is found that there is degradation in performance
of air cooled condenser under high ambient temperatures and
windy conditions. The heat rejection rate of ACC also depends
on surface condition of fins and thus its performance is
reduced due to external fouling of finned tubes due to weather
conditions and by internal fouling from condensate (Ammonia
corrosion). A Hybrid (dry/wet) dephlegmator achieves major
enhancement in performance when ambient temperatures are
high. Also shading of condensers is done for air-conditioning
units to mitigate the adverse effect of high ambient
temperatures due to solar radiation. Now a day’s wind walls
are used to reduce the effect of high wind velocity .second
option is to increase the fan speed Fin cleaning plays an
important role in heat rejection. External cleaning improves
air side heat transfer coefficient. In order to improve the
performance of an ACC Flat tubes inclined at some angle to
horizontal can also be used in place of conventional circular
horizontal tubes so that an improvement in heat transfer rate
occurs.

Solar distillation is one of the most promising technologies for supplying potable water. Simply due to its lower productivity, it has limited application. Only, when solar distillation is coupled with any mechanical source, then it increased productivity. Such, the device is called active solar still. The present review paper shows researches done on a solar distillation system for increment in distillate output.
The water and the energy are the two most essential things for the sustaining of life. Only less the 1% water is available for the society for direct use, out of which the maximum fraction has been polluted due to non-manageable industrial developments. A solar still is a device which can solve the problem of potable water without using the high grade energy .An overview has been given in this paper of introduction to solar still with a view to explain the principle and the mechanism of operation.

EXPERIMENTAL INVESTIGATION OF WASTE HEAT RECOVERY SYSTEM FOR DOMESTIC REFRIGE...IAEME Publication
The objective of this project was to determine the energy savings associated with improved utilization of waste heat from a domestic refrigerator. Domestic refrigerators maybe operate
continuously to maintain proper food storage condition. The continual operation of this equipment accounts more electrical energy consumption. Furthermore, a significant amount of waste heat is rejected by the condensers of refrigerator.
Classification, Advantages and applications, Commercially viable
waste heat recovery devices, Saving potential.
Waste heat is heat, which is generated in a process by way of fuel combustion or chemical
reaction, and then “dumped” into the environment even though it could still be reused for some
useful and economic purpose. The essential quality of heat is not the amount but rather its
“value”. The strategy of how to recover this heat depends in part on the temperature of the waste
heat gases and the economics involved.
Transient Thermal Analysis for Heat Dissipation from Engine Cylinder Block wi...ijtsrd
The cost of fuel and materials in all sectors is rising day by day. In the IC engine, the engine fails primarily because the heat transfer from the cylinder wall to the ambient air is inadequate. Heat is derived from the cylinder wall in the engine by means of convection heat transfer through the fins. In this study, a 3 dimensional numerical 3 D transient thermal state simulation was used to investigate the heat dissipation of the engine cylinder fin with holes of different shapes hexagonal and an elliptical . ANSYS 17.0 simulation software was used to research the physiognomy of the heat transfer physiognomies of an engine cylinder fin with and without hole. The results indicate that, the fin with an elliptic hole attain a temperature of 797.94 °C at 14 seconds in comparison to other where with hexagonal hole 798.02 °C, and without hole 798.14°C. So above values clearly shows that fin with an elliptic hole dissipates more heat as compare to fin with hexagonal hole or without hole. Fin with an elliptic hole have a total heat flux of 56122 W m² comparison to other where with hexagonal hole 49967 W m², and without hole 46704 W m². From the above results it is clearly shows that, the new proposed shape fin or fin configuration will greatly improve the heat transfer rate and increase the fin efficiency. Optimum results are obtained when we provide an elliptic hole in an engine cylinder fin Sunil Kumar Bharti | Prof. Rohit Soni "Transient Thermal Analysis for Heat Dissipation from Engine Cylinder Block with Different Shaped Holes in Fins using CFD" Published in International Journal of Trend in Scientific Research and Development (ijtsrd), ISSN: 2456-6470, Volume-4 | Issue-6 , October 2020, URL: https://www.ijtsrd.com/papers/ijtsrd35736.pdf Paper Url: https://www.ijtsrd.com/engineering/mechanical-engineering/35736/transient-thermal-analysis-for-heat-dissipation-from-engine-cylinder-block-with-different-shaped-holes-in-fins-using-cfd/sunil-kumar-bharti

Performance optimization of thermal systems in textile industriesIOSR Journals
Energy consumption has been growing very rapidly due to population growth, rapid urbanization
and industrial development. For future planning, it is important to know the current specific energy
consumption and the energy intensity in order to estimate future energy consumption. In the industrial sector
especially in textile units’ large amount of energy wasted due to improper working and lack of energy saving
measures. In this study, the various measures that causes the main energy losses are investigated .In the textile
dyeing sector, the main processes are associated with steam in various proportions. For the steam production,
steam boilers of different types are used for different applications. The efficiency of the boiler varies from one
industry to other based on various parameters such as quality of the water, fuel used, blow down quantity, etc.
Steam traps are also having influence on the boiler efficiency. In the case of steam leakage the performance of
the system decreases as the consumption of fuel increases to produce more steam. Thus by adopting various
recovery methods we can reduce the energy losses and fuel consumption.
Flue gas low temperature heat recovery system for air conditioningeSAT Journals
Abstract Huge amount of energy wasted through the flue gas in thermal power station causes great concern in recent years. Discharging hot flue gas in the environment is not only a wastage of energy but also increases the rate of global warming. Efforts are given world -wide to harness the energy for useful purposes. In this work, the waste heat of flue gas in a 350 MW thermal power plant is utilized in vapor absorption air conditioning plant. Gas to liquid multi-pass cross flow heat exchanger that have been placed in the existing space between boiler and chimney. The dimensions of the finally selected heat exchanger are 0.106m × 2.4m × 3.4m. The number of pipes required for the heat exchanger is found to be 12 using iteration method and temperature of water at the outlet of last pipe is 101.1℃. The extracted energy from the flue gas is used to heat water to be utilized in the generator of a vapor absorption refrigeration system that has produced a refrigerating capacity of 70 TR. approximately. Due to the corrosive nature of flue gas, heat recovery is confined up to the acid dew point temperature of the flue gas. Suitable software is used to find out the detailed design parameters of Gas to liquid multi-pass cross flow heat exchangers. Out of many feasible designs of heat exchangers, the most economic design is selected as the final design.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

I. INTRODUCTION
Generally based upon the potential of waste temperature sources, the waste heat has been identified as
High, low and medium temperature waste heat . The High and medium temperature waste heat sources of
identified processes have been well researched and fully developed technology is available to tap the these
sources, however the low temperature waste heat sources ,which consists of majority of waste heat rejection ,
has not been fully addressed . The technology which can be effectively used in colder places can not be utilized
in places like in Northern India. The reason being due to high Environmental Temperature, The low
Temperature waste heat recovery have lesser scope for use in warmer Countries like India. This study is
related to low temperature waste heat recovery and its effective utilization for efficiency improvement in
Industries in Typical Indian Conditions. The low grade heat resources are various in different Industries and
due to lack of knowledge, availability of technology, these sources are presently untapped , if utilized will
result in reduction in fuel consumption. This paper identifies some of such waste heat potential in Some
Industries like Hospitality ,small and big Industries. These recommendations may be replicated to similar other
Industries and Establishment where similar process of Energy uses and waste heat potential exists.
(a)This case relates to a hotel ,where , a compressor is used to supply compressed air for use in laundry. The
hot air discharge is at 65 o
C. The Laundry uses steam at 150 o
C to heat atmospheric air in fined heat
exchanger ,before same is induced to Tumbler for wet cloth drying . It can be used as preheated air before
steam to air heat exchanger . This will result in reduction of steam consumption in the drying of cloths . Since
the major part of steam consumption is in the drying process. The arrangement may be made as follows:

The individual tumbler top has opening cover and the air is sucked only when the hot air flow is
required. In this case the hot air ducting coming from the compressor is to be provided with option of
diverting the air to tumbler discharge ducting when non of the Tumbler is in operation. This arrangement will
help to reduce the steam consumption in Laundry. The potential saving identified in a gas fired steam
generator required for heating air will be Rs200036.53. Further with the investment of Rs 200000in
providing ducting ,the pay back period will be around one year.
(b) This case also refers to Waste heat reject from compressors in a molding Industry . It is noted that in
molding Industry one or two dish/bin washing machines are Installed . These are run every now and then to
wash the plastic containers. In the process of washing water is heated to 50o
C temperature .A typical Industry
in study around 60liters of water is heated at the required temperature with the help of 6 numbers of 3kw
Electrical Heaters. This heating can be achieved by hot air discharge from the compressor which is other wise
discharged in the atmosphere, this way saving in terms of electrical energy can be achieved. However since
the operation of the washing machine is not for longer duration therefore investment to switch over for
suggested heating may have longer pay back periods.
Alternatively it is noted that there is very appreciable quantity of Dematerialized water consumption
in the plant Thus average annual consumption of DM water is 542.88Tones and charges are
Rs163008/Annam. This requirement can be achieved by using waste heat based distillation of cooling water
coming out of machines. This way the waste heat reject of machines and compressor can be utilized in low
temperature vacuum distillation and there will be no Demand of Dematerialized water to be purchased from
outside. The cost of such low temperature waste heat based vacuum distillatory will be around Rs1000000 and
pay back period will be 6.13 years. The IRR @ 12% discounting is just 2.47%. However it is attractive to note
that waste heat will be utilized and out side dependency to demoralized water will be reduced/stopped.
(c)
The industry in study is involved in melting of brass, copper ,zink scraps and metals and scraps
purchased from the market melted and reshaped for further uses. The processes being followed in the
industry are melting of scrap and metal pieces to provide a shape by casting for rolling, ,then heat treatment
for stress relieving and prickling for surface cleaning . The Melting furnaces are induction type electrical
furnace., the Heat treatment furnaces are diesel fired. Further in the same Industry the Hot water for
quenching in die casting is available in temperature range of 45-50o
c, is passed through cooling tower to
reduce its temperature for further uses. The heat instead of wasting in the atmosphere can be utilized to
generate distilled water in waste heat based vacuum distillation .This will reduce the cost of electricity used in
running cooling towers. Presently the prickling station has heating arrangement with 96 KW electrical heater
and one station with facility of Natural Gas heater. This requirement can be met by use of waste heat of
annealing caste blocks, rolled pieces , exhaust gases/flue gases from the annealing/heat treatment stations
through air /flue gas heat exchangers by passing the air over the left over casted blocks, rolled pieces and
then pass this hot air at prickling station for drying etc. Induction cooling air discharge which is available at
around 80-90 o
c also can be utilized to provide heat to replace 45 KW electrical heater meant for prickling
station. The arrangement can be following type:

(ii)Alternatively the hot quenching water of die casting in melting furnaces available at 50o
c can be
circulated through a water to air heat exchanger to preheat the air before further passing it over the rolled
coils to gain further temperature before finally passing it through prickling station .The blown air in hot
drying chamber can be led to the Air pre heater of furnaces and then to burners or for water recovery as
suggested in at (i) above..
(iii) The hot blocks of metal casting are stored in such Industry at a specified place to cool down to room
temperature by annealing process. The heat available to be utilized as sensible heat from casting ,
which is stored in open air before put to further process. These sources of heat can be stored at the
nearest point at pre fabricated platform where from the cold air is blown. This air is then compressed and
blown to prickling chamber. The return hot air from the prickling chamber can be circulated through air
pre heater and then to burner of diesel fired heat treatment furnaces.

The annual saving in above arrangement is estimated to be 45 KW of electricity with total 224640 units of
electricity at the @ 16 hrs per day effective operation of heaters and factory operating 6 days a week. The total
cost saving will Rs 1347840.00 with investment of Rs800000. The total saving due to above is 1347840.00
and pay back period is 0.59 years.
(d) This case study is related to rolling mills .The steels ingots are rolled to sheets ..
5. Identification Of Some Of Low Temperature…

The hot rolled steel coils are slit into required size and then after that warm hydrochloric acid is used for
cleaning rolled sheets to remove dirt and dust.Heat treatment process is completed with combination of
heating and annealing bases. The furnaces under study are LPG fired. In the heat treatment and annealing
process, the general temperature of heating is kept in the range of 740-850 o
C. Then furnace cooling at 600
o
C, the annealing process has lot of heat rejection, The temperature of the job reduces from highest around 600
o
C to room temperature. This heat can be utilized for LPG preheating which is presently heated up to 40o
C by
use of 10KW electrical heater. This arrange may require to shift the LPG station near chimney and from there
the preheated LPG can led to required place. Only part of flue Gas can be used to preheat the LPG and part of
the flue gas can be used to heat the seal cooling return water for use in Hydrochloric acid pre heating. This
will stop the requirement of boiler which other wise requires 210 liters of HSD per day for Hydrochloric acid
warming. Alternatively the HCL can directly be heated with flue gas. This will further reduce the use of pump
and piping and requirement of heat exchanger will be one as shown in above diagram.
Thus the estimated saving such type of Industries with above arrangement will be 10KW in electrical heater
of LPG, resulting in 37440.00 units of electrical savings @ 12 hrs and 6day/week of effective running which
is equivalent to Rs 268211.77. With capital Investment of Rs 300000 the payback period is 6.7 Months.
II. CONCLUSION
The above illustrations are some of the possible uses of low Temperature waste heat in typical Indian
Industries . These studied are based on the presumption that uses are in-house and these require minimum
Investment. Detailed techno Economic Evaluation of these potentials for adaptation in particular Industry of
same segment needs to done before final conclusion for Implementation of any of suggestions in particular
establishment.
