A cold room company gets asked the same thing twenty times a week. How big do I need, and what will it cost? Most of those enquiries never turn into a quote, because answering properly costs an engineer half an hour and the person asking has already messaged two competitors.
I build the thing that answers it on your own site, then hands your engineer a finished specification instead of a first question.
Proof, not a mockup
Put in the room size, what you are storing, how much arrives each day and the temperature you need. It returns the refrigeration duty, where every kilowatt of that load comes from, an indicative budget, and the solar array, battery and inverter to run the whole thing off grid.
The numbers are not invented. Transmission, product, internal, infiltration and equipment loads follow the ASHRAE Refrigeration Handbook. Specific heats come from Siebel’s equations using water content, so a commodity nobody planned for still gets a sensible answer. Efficiency is derived from the actual evaporating and condensing temperatures rather than looked up, which is why a Lagos fish freezer and a Manchester pharmacy store size differently without a second version of the tool.
The demo carries an invented company name, Meridian Cold Chain, so you can picture yours in its place.
What I do
I work as one person, so you deal with whoever is doing the work and nothing gets lost between an account manager and a developer. It also means I take on a small number of projects at a time, and I say so up front rather than after you have paid.
How it runs
Talk to me
If that question has a number in it, there is probably a tool in it. Send me a line about what you sell and I will tell you honestly whether it is worth building for you.
