The Refrigerated Urban Van

1 · The job

Chilled or frozen goods, doors opened repeatedly, temperature maintained regardless of how slow the round is.

2 · The proposed vehicle envelope

Short-wheelbase insulated body, single cab.

3 · Target payload

750 kg

A target, not an achieved figure. Nothing here has been engineered or measured.

4 · Target working range

150 miles in urban use

A requirement drawn from the work, not a published or calculated range.

5 · Operational requirements

• Rear doors opened at every stop
• Temperature logged and audited
• Long idle periods in traffic

6 · Principal compromises

• Insulation and refrigeration consume payload and energy at the same time.
• The worst case is a hot day with a slow round — the opposite of the range test case.

7 · What would need engineering validation

• Energy demand of refrigeration across a real urban round
• Insulation mass against payload target
• Temperature recovery after repeated door openings

Engineering assessment required

8 · Who might benefit

• Food distribution
• Pharmacy and clinical logistics
• Independent retailers
