ROCKLEDGE, FL — [Date Nov. 22, 2019] — Mainstream Engineering Corporation has been awarded a contract from NASA for an Extreme Temperature Vapor Compression Heat Pump.
NASA needs a dramatically improved thermal management system for use in the equatorial lunar environment, where surface temperatures can vary between ‑300°F and 212°F. To address this problem, Mainstream has been contracted to develop a vapor compression (VC) thermal management system suitable for long duration operation in this harsh lunar equatorial environment. The objective of this NASA contract is to design and demonstrate the key enabling technologies needed to produce a fully functioning system. The most significant technological innovation needed is the development of a highly reliable microgravity compressor. Mainstream has tremendous experience in this area having developed high-G compressors for military aircraft as well as the development of the refrigerant compressor used in the refrigerated centrifuge on the International Space Station. Mainstream’s approach leverages their experience with spaceflight-proven microgravity compressors and has the potential to benefit any space-based thermal control system including manned lunar habitat climate control, food preservation freezers, low lunar orbit missions, and Venus exploration missions.
