Introduction

13th February | 13:00-18:00 Hrs | CEESAT Dept

Freeze Over!

Here is an event that calls for you to build a contraption to cool water from room temperature in 5 minutes. Sounds simple enough. But wait, there’s a catch… No electrically dependent cooling techniques. That means no fridges or freezers. Intriguing? In ΔT, you are invited to add a whole new dimension to the ancient art of cooling water. Come up with ideas as you try to gain a delta over your opponents in this chilled out event!

It could be an ice-vat with a piece of your intellect, so it's better than what a block of ice can serve; or even a refrigerator unit sucking out the internal energy from water. But of course for reasons most conspicuous, if your model can work well enough JUST for the 5 minutes... it is not the winner...!!

Well, sort it out.... It means a lot of cash!

Deadline for uploading your abstracts is 10th February.
Upload your abstract over here. Please ensure you register first! You do not need to upload while registering.
Problem Statement

Design and construct a unit that can cool water from room temperature  without the use of electricity in any form.


Participants are required to submit a brief write up on their prototype giving the specifications and materials you are using for the model. Use the registration form to upload your synopsis

Shortlisting for the on campus finals will be done based on the synopsis.

Shortlisted teams will be intimated at the earliest through email.

Last date for uploading is 10th February.

Rules & Regulations

Team Specifications

A team may consist of a maximum of three members.

Setup Specifications

  • No electrical energy input is permitted
  • The maximum height permitted for the setup is 1 m
  • The dimensions of the equipment used in the setup are to be decided by the teams
  • Design must however make  room within a floor area of 100cm X 100cm. Crossing this limit by small figures will not be condemned.

Rules

  • The time allotted for cooling is 5 minutes. Countdown will start only from the time water is given to the teams.
  • No external materials (eg: funnel etc) will be provided.
  • Mechanical methods of supplying work are allowed for cooling.
  • All coolants and refrigerants are allowed.
  • The volume of liquid that goes in must be same as output. Entrainment or increase in volume presumably because of the coolant(such as ice) will lead to negative points.
  • The characteristics of the output liquid must not change at all. This includes even physical characteristics like taste and colour.
  • The cooled liquid must be collected in a separate container which will be provided by us. Participants can also bring their own containers.
  • The temperature of water in the collecting container will be measured at the end of 5 minutes
  • Slushy solid mixtures in the outlet will disqualify team.
  • The organizers reserve the rights to change any of the above rules as they deem fit. Changes in rules, if any, will be highlighted on the website and registered participants will be notified.

Judging Criteria

  • The final temperature of the liquid.
  • The volume of the output liquid as collected in the final container.
  • (VOLUME AT INPUT) – (VOLUME AT OUTPUT), if a real number other than zero leads to negative points.
  • Lifetime of the design (as in; for a heat exchanger deploying a coolant, lifetime is lesser as compared to usage of a refrigerant combined with mechanical means.)
  • Cost effectiveness.
  • Creativity & innovation.
  • Portability and Aesthetics.
  • Design effectiveness, incorporating durability issues.
  • Participants may note that volume accounts for 30% of score, and the temperature 50%; while the rest is for the other factors. A design with long life (i.e. giving scope for recycling will take a bonus of 50 points). This should help the team in making a good decision, compromising between greater volume and temperature difference.
  • Participants should submit a design report of the process used including the design and cost calculations
  • The judges' decision is final and binding

FAQ

FAQ

  • What does the lifetime refer to exactly?
    The model presented will be assessed for its reusability. i.e, mere usage of a coolant working purely on its ability to absorb heat, wearing out in course of time is not very efficient and will hence will fare very poorly as compared to the usage of a refrigerant which maybe recycled also. A design with long life will take 50 points.
  • Can ice be used as a coolant?
    Ice is available from cooling in freezers employing electricity. There is hence the general argument that this is an indirect form of electricity usage. However we prefer to look at ice as a coolant only, which maybe available naturally also as was seen in the ancient practice of transporting ice to the aristocracy of less fortunate areas.
    Our "game plan" though clearly states that lifetime is a crucial point for assessment. Hence ideas of mere thermal contact may give the least efficient design that may not survive competition. If you still wanna stick to heat transfer, increasing the surface area of contact will be a wise decision.
  • I am thinking of bringing a huge carton of ice and putting the water inside. How's that?
    Terrible idea! Your lifetime is extremely poor, the carton's too big and heavy; given the time, the temp drop's extremely low and remember taste cannot change, volume must not change and the output liquid must not be a slushy mixture with any solids.
    Hence, it is advised to refrain from such bloopers.
  • Why this hype and hoopla about no volume change and taste change, blah.. blah.. anyways?? What's the big deal??
    To start with the less ambitious project. You got to carry water in an earthen pitcher to your friends (some 50 guys) stranded in the middle of a very hot desert, and you got just one very fragile animal to take u there.
    Or, as in "Back to the future" where the professor in 1858 build this really huge thing to bring out a block of ice..., well you need nt make ice but drop the temperature with something more sleek and you win straightaway!!
