Abstract To develop a home heating system with high efficiency, the outdoor temperature is not the only parameter to be considered but also disturbances such as ventilation, door/window openings and personal lifestyle. The aim of the project is to develop the home heating system which adapts itself to changing customer demands using fuzzy logic. The energy consumption and the outdoor temperature of the house were monitored over a period of one year to produce the data required to program the fuzzy controller and thereby the appropriate set temperature will be determined. When load disturbances such as door/window openings are given, there is an increase in the energy required by the heater. This additional energy is obtained as an output from the fuzzy controller and given to the heating system. The design, optimization and implementation of the fuzzy controller are supported by LabVIEW software

Air Water System Design using Revit Mep for a Residential Buildingijtsrd
In this project we discussed the study and performance of air conditioner, air refrigeration and water conditioner system in a single unit. The main objective of this project is to develop the multifunctional system which can provide refrigeration effect, cold water and air conditioning effect with in regular air or space conditioning system. Air and water systems conditioning spaces by distributing the both conditioned air and water to the terminal units installed in the spaces for which the basic plan is given by civil department and the basic design is done by using REVIT MEP software. The air and water are heated or cooled in a central mechanical equipment room. The air supplied is termed as primary air to distinguish it from the recirculated or secondary room air. By using the peak cooling load values obtained in the heating and cooling load calculations the ton of refrigeration values for individual and total area is calculated which will be helpful for selection of accurate design for the residential building.

Each solar thermal plant can provide different parameters to be treated and evaluated, mostly temperature measurements, pressure specifications, heat transfer values. This data collection can be quite expensive taking into account the important number of sensors and data loggers and their specifications. Hence to assure flexibility in the data collection at a low cost, many hardware and software specifications can be adopted. Here we built an inexpensive data logger based on the Arduino board and IDE to collect and store incoming data from Resol DeltaSol regulators integrated in different solar water heating systems. The objective of this study is to allow massive synchronized measurements with high resolution to be stored into an SD card through the Arduino platform. The measurements are given by multiple sensors (temperature, pump speed, relay states) connected to the regulator. The results from the tests of the plant connected to the data logger are provided later on, alongside the commercial aspects of the built data logging device. After a month of daily measurements, the data logger showed an outstanding performance with an extreme low cost compared to industrial datalogger.
Application of thermal imaging for detecting cold air leak location in cold s...IJAAS Team
Nowadays Cold storage has been playing an important role in preserving the perishable food products like fruits, vegetables, dairy products, fish, and meat etc. The major problem of cold storage is unwanted energy transmission during the operation. It is necessary to maintain the constant temperature during storing the products. There are different kinds of energy loss happening during the operation. One of the major causes is cold air leaking from the inside of the cold room to outside. It is due to poor insulation and improper maintenance of cold storage. It is very difficult to identify the exact location of the leak by the naked eye. In this research work, the cold storage was inspected with the thermal imaging system. Thermal cameras are highly sensitive to temperature and it can detect the variation of temperature ranging from 0.1°C. The measured temperatures are further converted into a colour based pattern. It is known as thermogram. These colour-based thermal patterns are further processed for identifying energy transmission location. It is done by applying various image processing methods such as histogram equalization, diffusion error, otsu thresholding and morphologic function. These techniques were applied to images of cold storages and exact cold air transmission locations were identified.
ARM Based Climate Controlled Wearable JacketIJTET Journal
Thermo-electric (TE) technology is used in both electricity generation and air-conditioning. The Thermo-electric coolers(TEC) uses Peltier effect which converts the electrical energy applied from the ends of the Thermo-electric module into the temperature difference. The main objective of the work is to design a highly reliable and wearable jacket that controls extreme temperatures say working in thermal power plants, within the jacket. The extreme temperatures can be monitored using temperature sensors placed on both sides of the Thermo-electric cooler module and controlled using ARM LPC2148 Microcontroller. In Industries, this jacket provides a more practical and safer solutions for human working under extreme temperatures. Furthermore, this jacket can also be applied as a good warmer one for human beings working in cold regions(say Polar regions).

during-day better control of the temperatures of the classrooms. In Powers
Annex, Chilled Water Air Handler Unit is used and controlled by analog
controller set to 73°F. 30% of air is conditioned outside air which is an
important aspect of the classroom – air quality for students. Simple physics is
used to calculate the amount of energy used for cooling. Someone said “a
Heating, Ventilating, and Air Conditioning system is like a faucet and your
building envelope like a cup. The leakier your cup is, the more you have to open
up the faucet1.” For example, a room may be hot in the morning and cooler in
the afternoon because the temperature outside of the building is in constant
movement, and therefore more or less cooling is needed based on the outside
temperature. Other factors impacting heat gain are location of the room;
equipment in the room; the number of students in the room and their activity
level. To be precise, heat flow depends linearly on the difference of
temperatures of the inside and outside, ΔT, insulation of the building, U-value,
and square footage of the surface area of the perimeter envelope, A, i.e.,
in BTU/h. A more modern formula for
heat gain is
given in BTU, where CDD stands for
Cooling Degree Days. CDD is the number
of degrees a day’s temperature is higher
than a set room temperature.

After years of complaints from professors, staff, and students that certain
rooms and/or buildings at Barry University are very cold, we decided to
look into efficiency of air conditioning (A/C) that is in use. There are
several items that can be looked into when it comes to improving A/C
efficiency such as temperature of the room, humidity, air quality, A/C unit
itself, and level of CO2 in the room. For the purpose of this project we will
focus on evaluating room temperature and humidity based on the
outside climate conditions. In particular, we will collect temperature and
humidity measurements of several classrooms. We use the Arduino
platform to develop an economical temperature and humidity
logger. Arduino is an open-source microcontroller unit that utilizes an 8-
bit AVR chip and other hardware which allow it to be easily
programmable and interfaceable . We interface an Arduino Uno R3 with a
data logging shield for SD data storage and real time clock capabilities,
and an HTU21D-F high precision temperature and humidity sensor. The
Arduino is programmed to awaken from sleep at set intervals of time to
write the sensor values to the SD card. Once data is collected, we will
compare it with recommended room temperature and humidity,
calculate possible energy savings, and essentially obtain cost savings.
An Arduino Uno R3 microcontroller is used as the platform for the sensors and
SD memory card. The HTU21D-Fby Adafruit is used as a dual sensor. It is able
to detect humidity with an accuracy of ±2% and temperature with an accuracy
of ± 1%. For data logging, the Adafruit Data Logging Shield** was used. For
convenience, it houses a built-in Real Time Clock (RTC) with a dedicated coin
cell battery for persistent time keeping. The shield does not come with soldered
headers to plug in to the Arduino pins, so stacking headers were purchased and
soldered onto the shield. Likewise, plain headers were soldered onto HTU21D-F
sensor, which in turn was soldered onto the prototyping area in the center of
the data logging shield.
Both components communicate with the Arduino using I2C protocol, a
communication standard that uses only two pins and can handle interfacing
many complex boards together. The SCL pin is the clock (timing) signal, an the
SDA pin is the data signal. Connections as shown below were soldered from the
sensor pinouts to the Arduino pins. The software libraries “SD.h”, “Wire.h”,
“Adafruit_HTU21DF.h”, and “RTClib.h” were used to call sensor values and write
data. Finally, the Arduinos were powered from 6 AA batteries in series.

Many buildings in Florida are perhaps much cooler than necessary, the
reason being not just high temperature outside, but the combination of
high temperature and high humidity. “To most people 75°F and 60% RH
feels like 79°F and 30% RH1.” Turning the A/C on is the easiest way to get
rid of moisture in the air, but what is the aftermath of that? In recent
years we have been hearing a lot about global warming due to human
impact; scientists have predicted the rise of the ocean, with a great
impact on Florida’s coast; many organizations are promoting
Earth/energy saving. “Florida’s per capita residential electricity demand
is among the highest in the country, due in part to high air-conditioning
use during hot summer months” (FESC). The situation at Barry
University is not different. Most classrooms are freezing. We watch
students wearing sweaters inside while outside is 90°F and at the same
time we fear the rise of the ocean? It is clear that over-cooling means
wasting energy, so should we sit and watch or should we do something
about it?
In this project, we investigate A/C efficiency of Powers Annex building;
we calculate possible energy savings per year and turn this into cost.
Finally, based on our results, we give an estimate of the possible energy
and cost saving of the whole university.
Many factors impact efficiency of A/C such as temperature, humidity, air
quality, A/C unit itself, insulation of the building, etc. For the purpose of
this project we are looking into energy savings if analog controllers were
replaced by digital ones and controlled remotely. This does not just allow
for temperatures setbacks when classrooms are not in use, such as nights
