Objective
The goal is to develop alternative air handling units or systems to cool the cabin area and electronics, save costs across Army-wide infrastructure and eliminate the need for large specialty equipment recovery machines, which are required to maintain refrigerant systems.
Description
The development of a non-refrigerant-based cooling system directly supports the Army Climate Strategy and the government’s efforts to reduce the production and import of HFCs to 15 percent of the current levels by 2036.
Rather than adapting military air conditioning system designs to address the flammability of HFO-1234yf, this design strategy aims to eliminate the refrigerant loop. The non-refrigerant-based system would make it unnecessary to purchase and store refrigerants while alleviating leakage issues among current systems.
Phase I
Test a quarter-scale proof-of-concept version of the cooling system in a thermal chamber for performance at the Special Systems and Component Engineering (SSCE) laboratory.
Phase II
A Full-sized system must be installed in a vehicle.
Phase III
Document and resolve any issues while demonstrating the system’s performance within a vehicle. Ensure dual-use, effective and compliant application, as global regulations will continue to tighten around the kinds of refrigerants that are usable within a variety of industries.
