This document experimentally investigates the performance of a vapor compression refrigeration system (VCRS) using an air-cooled condenser versus a water-cooled condenser. The study builds and tests a VCRS setup with both condenser types. Results show that using a water-cooled condenser improves the system's coefficient of performance (COP) by around 25% over an air-cooled condenser, due to better heat transfer. The water-cooled condenser provides more efficient cooling of the compressed refrigerant compared to air-cooling.

There are many applications where

loads at different temperatures. For example, systems for hotels,
large restaurant, institutions and food preservation industries. In
these cases, it is necessary that each location is cooled by separate
evaporators to maintain the particular temperature and produce
the required refrigeration load. Hence it requires different
refrigerating units with single evaporator for each location.
Instead it will be beneficial to use a refrigerating unit with

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
use has brought an increased interest in use of Air Cooled
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.
Experimental Investigation of a Household Refrigerator Using Evaporative-Cool...inventy
The objective of this paper was to investigate experimentally the effect of Evaporative-cooled condenser in a household refrigerator. The experiment was done using HCF134a as the refrigerant. The performance of the household refrigerator with air-cooled and Evaporative-cooled condenser was compared for different load conditions. The results indicate that the refrigerator performance had improved when evaporative-cooled condenser was used instead of air-cooled condenser on all load conditions. Evaporativecooled condenser reduced the energy consumption when compared with the air-cooled condenser. There was also an enhancement in coefficient of performance (COP) when evaporative-cooled condenser was used instead of air-cooled condenser. The Evaporative cooled heat exchanger was designed and the system was modified by retrofitting it, instead of the conventional air-cooled condenser by making drop wise condensation using water and forced circulation over the condenser. From the experimental analysis it is observed that the COP of evaporative cooled system increased by 13.44% compared to that of air cooled system. So the overall efficiency and refrigerating effect is increased. In minimum constructional, maintenance and running cost, the system is much useful for domestic purpose. This study also revealed that combining a evaporative cooled system along with conventional water cooled system under the condition that the defrost water obtained from the freezer is used for drop wise condensation over condenser and water cooled condensation of the condenser at the bottom using remaining defrost water would reduce the power consumption, work done and hence further increase in refrigerating effect of the system. The study has shown that such a system is technically feasible and economically viable

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

set-up of vapour compression refrigeration
conditioning system has been built and is coupled
with the Air cooled and water cooled condenser. The
two condensers i.e. air cooled and water cooled
condenser are placed in parallel to each other with a
proper arrangement of handset valve to guide the flow
of refrigerant as required. The effects of these two
condensers on the cycle performance at different
ambient conditions have been measured.
Experimental results show that the use of water
cooled condenser and air cooled condenser improves
the COP as well as reduces the power consumption as
compare to the air cooled condenser. The COP
increase in case of water cooled condenser is about 25%
whereas in evaporatively cooled condenser the COP
improvement is of 20%.
III.WORKING OF EACH COMPONENT
Compressor: The low pressure and temperature vapor
refrigerant from evaporator is drawn into the
compressor through the inlet or suction valve, where
it is compressed to a high pressure and temperature.
This high pressure and temperature vapor refrigerant
is discharged into the condenser through the delivery
or discharge valve.
Condenser: The condenser or cooler consist of coils of
pipe in which the high pressure and temperature
vapor refrigerant is cooled and condensed. The
refrigerant, while passing through the condenser,
gives up its latent heat to the surrounding condensing
medium which is normally air or water.
Expansion Valve: It is also called throttle valve or
refrigerant control valve. The function of the
expansion valve is to allow the liquid refrigerant
under high pressure and temperature to pass at a
controlled rate after reducing its pressure and
temperature. Some of the liquid refrigerant evaporates
as it passes through the expansion valve, but the
greater portion is vaporized in the evaporator at the
low pressure and temperature.
Evaporator: An evaporator consists of coils of pipe in
which the liquid vapor refrigerant at low pressure and
temperature is evaporated and changed into vapor
refrigerant at low pressure and temperature. In
evaporating, the liquid vapor refrigerant absorbs its
latent heat of vaporization from the medium which is
to be cooled.

I. INTRODUCTION
Vapor compression refrigeration system is an
improved type of air refrigeration system in which a
suitable working system, termed as refrigerant, is used.
It condenses and evaporates at temperatures and
pressures close to the atmospheric condition. The
refrigerants, usually, used for this purpose are
ammonia, carbon dioxide and sulphur dioxide. The
refrigerant used, does not leave the system, but is
circulated throughout the system alternately
condensing and evaporating. In evaporating, the
refrigerant absorbs its latent heat from the brine (salt
water) which isused for circulating it around the cold
chamber. While condensing, it gives out its latent heat
to the circulating water of the cooler.In this project
we have concentrated our study on water cooled and
air cooled condenser VCR systems and found out
experimentally the performance improvement in COP.
II. CONSTRUCTION
In the present work we have concentrated our study
on the water cooled and air cooled condenser for the
domestic VCRs system to have higher COP than the
air cooled condenser. The performance of the water-
cooled condenser is elevated by immersing the full
condenser in the water tank. In case of air cooled
condenser the cellulose pads are used to get the cool
air which is further used to cool the condenser.The
experimental setup consists of a single stage vapour
compression system with the basic components i.e.](https://image.slidesharecdn.com/ijsrst1841158-180429083900/85/Experimental-Investigation-Performance-of-VCRS-system-by-using-Air-cooled-Condenser-Water-Cooled-Condenser-1-320.jpg)
