This is interesting. . .

[Mex-Busnut]

A central heating system?

[luvrbus]

Is that supposed to be a chiller set up also or just for heat I cannot tell by the photo

[sparkplug188]

Hmm... looks like a water heater, water hammer arrestor, waste and fresh water tanks, power distribution panel, and a small ducted heater. I don't see anything that looks like a chiller.

I have a friend with a setup that looks similar he has a small chiller he made with a fridge compressor and the water heater supplies the heat, works pretty darn good in the right weather that is neat and clean install in the photo who ever done it  IMO

It looks like a Heater/ AC small commercial unit like we have on our trailer?

Left is gray water tank, then blue accumulator tank, below the blue tank is the electric water heater, green cabinet-unknown, (2) red is Diesel fired hot air heaters. On bottom is a ball valve for winterizing. Good Luck, TomC

Many moons ago a company I worked for (1970's) had diesel fired heaters in there service rigs that worked on drilling rigs in the oilfield out in west texas. Had about 30 or 30 running at at a time in small sleeper operator/cabs for the men. Tried 2 or 3 brands and had heck with all because of the rough oilfield roads the trucks encountered. If it wasn't dirty fuel (and we run filters on them) it was just shook until they had problems. They were good when they worked but kept a supply on hand and was constantly changing them out and sending them in for repair.

Well the blue water pressure tank looks familiar.  Got that on my self contained water system for my home. After that I am lost.
