PRODUCT DESCRIPTION The Controller will be used control the internal temperature of an insulated aluminum container which stores refrigerated food for up to 24 hours. Food will be approximately 3.5 degrees C (38 degrees F) when placed in the container and should maintain that temperature (+/- .5 degree C) for the duration of storage. MOEFLY COOLER CONTROLLER SPECIFICATIONS Low power for 12V DC 9800mAh Rechargeable Li-ion Battery operation INPUTS 1. An input to read a thermistor for temperature 2. An input to determine when AC or auxiliary power is present OUTPUTS 1. PWM or switching DC power supply to control TEC from 30 to 100 % 2. Control for bicolor LED 3. Output to charge battery 4. Possible output for Fan control (power savings) INPUT SECIFICATIONS 1. Calibrated to read temperature at 3.5 Deg. C +/- 0.1 degree Range would need to be accurate from 0 to 6 Deg. C 2. Only to determine if Auxiliary power is present to adjust cooling set point and power consumption. OUTPUT SPECIFICATIONS 1. Capable of powering TEC at full power when on aux. power for faster cool downs, And cutting back to 30% for battery conservation. Current TEC is 4 to 12 volts @ 0 .8 to 3 Amps 2. Capable of powering bicolor LED when in Aux power red when cooling but not at temperature And green when at temperature and ready for food. 3. Capable of powering small fan, less than 200 mA. (Possible fan control to stop fan when cooling is at minimum and fan is not needed.) CURRENT TEC Model: TE-127-1.0-2.5 Voltage: 12V DC 9800mAh Rechargeable Li-ion Battery Couples: 127 Umax(V):15.9V. Imax(A):1.9A. ΔTmax(℃)≥66 QM(W):18.3W Dimensions: Approx. 30 x 30 x 4.8mm (L*W*H) COOLING SCHEME 1. When on Aux. power TEC will run on full power to minimize time to set point. 2. Aux set point being 1 deg. C. Low enough that when removed from Aux. power there would be some added help for batteries to maintain power saving set point of 4.5 Deg. C, but not low enough to freeze food if left in cooler for extended period of time while on Aux power. For example, if food were left over night to be ready in the morning. TESTING TIME FOR COOL DOWN • Max capacity 12volts • 20 Minutes cool down • Minimum needed: 4.2volts

I have over 35 years experience as an electronic design engineer, please see my profile for more details The current price and timescales are only place holders to allow me to communicate with you I have designed temperature controllers before so this should be no problem. Can you supply a data sheet of the Peltier device and the battery you want to use? Also would you want to display the actual food temperature? Do you expect to have a calibration routine in order to get such tight accuracy? If you think I can help then please send me further details Best Regards Dave Lelievre

Hello. Your range of price is too big for that project (if I understood requirements correctly), but I can't write lower price. My estimated price is approx. 150$ I have an experience in similar jobs (made a cooling device with Pelite elements) and can make that job for you. With best regards. Maxim Bulowsky

I've already worked on a similar project for two local clients. Moreover, I did a similar project during my studies in engineering which was named as "Room Conditioning System" which included a small fan for temperature control and temperature sensors for the temperature measurement and monitoring. Additionally there can be a display to indicate the fan speed, current temperature, desired temperature, keypad to change the parameters. What I will provide? =============== 1- Complete circuit design 2- Complete code 3- Software simulation of the project (usually on Proteus/Orcad, if required) 4- Bill of materials. 5- Guidance to build prototype on your own side. 6- Prototype built and video proof (costs of components etc. to be provided by the employer). 7- A small report, comprising the design + calculations + procedure etc. of the product (around 5 pages. For professional writing, I charge $10/100 words). 8- 110% SATISFACTION GUARANTE. Contact me so that we can discuss the details and finalise the terms. Regards. Faraz Ahmad

Hi, I am an experienced engineer that specializes in new product design and development. This includes all aspects of product development (i.e. feasibility, HW design, Firmware design, SW design, Prototyping, Patent assistance, Production assistance, etc.). I have designed many controller applications and am familiar with heating and cooling algorithms and components. I have read the product description and I can design and test the circuit panel board for you. I estimate the following major tasks are necessary: A. Operational Overview (specifications of major components, operational determinations, etc.), 1 week B. HW Design (schematic, PCB layout, fabrication files, BOM, etc.), 1 week C. Firmware Design (MPU/CPU operational structure, functionality, etc.), 1 week D. Firmware Programming (Coding/Debugging and Testing of Firmware program, etc.), 10-14 days E. Parts/Materials Acquisition and Initial Testing, 7-10 days F. System Modifications (if necessary), 1 week G. Final Testing, 1 week H. Final Documentation (Datasheet, Operation Manual, etc.), 1 week At the completion of each of the above a detailed report; including all work done, issues encountered, solutions applied, suggestions, etc. will be submitted for review. NOTE: All parts/materials/shipping are the responsibility of the client. I am able to get started immediately and hope to be able to work with you on this project design and development. Sincerely, Michael Cooke, PhD, EIT IHS Consultations

Hello, To be frank, But being well experienced in this kind of projects I ask you 2 questions. Though I can do your project very well, I ask this practical questions at first. 1) Can you send the Cooler to me in India or the vendor who can supply to me or something closer to the real ? 2) If the above point not practical, and If I make the Software for the project with few assumptions, Are you ready for few recursions ? I can upfromt sendyou the HW with a pre loaded Bootloader and I can keep sending you the hex file and you can flash them with a Window PC software. The reason because, many may agree to do this project, But this project must be executed with real system or with a Good counter part at the device. I do not want to mis lead and waste your time by false commitment. You pls come for chat and we can quickly discuss. (My feelancer Chat may show offline, but configured in my mobile and my mobile is active as long I m awake! so I will revert back quickly in minutes ) Thanks

Hi, I have experience in Peltier Technology. I have vast experience in Fan speed control ( I have built several circuits using fan / blower speed control) I have vast experience in Temperature reading / control (most of the boards I built do have Temperature Control PID and ON/ OFF). I have also worked with Switch Mode PSU (design / Building and Testing) I can support you in production - Design and building of test Jigs to test the controllers. I can deliver you full testing line for controller and final product Testing. I have already worked in Testing TE units. Thanks for looking into this message and please understand this is not a project which can be done in few days considering you will have a full working product (TE PCB Controller).
