This compact heat exchanger has no moving parts
The ACT-HP-AAXH heat pipe air-to-air heat exchangers can be fitted to new or existing HVAC systems. The AAXH is a counterflow heat exchanger and energy-recovery system that is based on the company’s high-performance heat pipes. The system is used to pre-cool or pre-heat incoming building supply air, and is designed to ensure indoor air quality while preventing cross-contamination between isolated airstreams. The system provides savings related to heating and cooling costs that typically allow for a payback period of one to two years, says the company. — Advanced Cooling Technologies, Lancaster, Pa.
