R717 Ammonia Refrigeration Systems Market – View in Detailed Research Report

Market Snapshot

The R717 Ammonia Refrigeration Systems Market reached USD 6,200 million in 2025 and is projected to grow to USD 10,400 million by 2034, reflecting a CAGR of 6.5% over the 2026–2034 period. The expansion is underpinned by tightening regulations on high‑GWP refrigerants, a growing appetite for energy‑efficient cooling in food processing and cold‑chain logistics, and the increasing deployment of ammonia‑based solutions in renewable‑energy‑coupled systems.

What Is R717?

Ammonia (R717) is a colourless, odorous gas that offers a high latent heat of 23 kJ kg⁻¹, enabling superior coefficient‑of‑performance in refrigeration cycles. Its zero global‑warming‑potential and negligible ozone‑depletion potential make it an attractive alternative to synthetic refrigerants such as HFCs and HCFCs. Ammonia’s thermodynamic profile allows for lower compression ratios and higher evaporating temperatures, which translate into measurable electricity savings for large‑scale commercial and industrial cooling equipment.
