HPT Announces the Launch of a New Energy Recovery Product
The HRM-V™ Split Passive Recovery with Dynamic Seasonal Offset (DSO™)

HPT is proud to add another product to our split passive HRM-V™ line. This new product is intended to optimize the performance of systems where supply and exhaust air streams are separated by a certain distance and on the same level.

The remarkable design of this new HRM-V™ product, optimizes energy recovery performance 20 to 35% over older side-by-side (no offset) designs, and attain equal amounts of recovery for both heating and cooling. Optimized performance is achieved by using integral face dampers to direct flow through sections of the heat pipes to create an offset effect, thus enhancing performance. The dampers are controlled from a single heating/cooling changeover signal that always keeps the condenser side (colder air stream) of the heat pipes higher than the evaporator. 

Moreover, and an industry first, HPT has acquired certification to AHRI standard 1060 for this product and the rest of our HRM-V™ split passive line as well as ETL listing to UL standard 207. 

If you have any questions about the above, or want a copy of our Application Paper on this new product, please email us at sales@heatpipe.com.

HPT's Wrap-Around Heat Pipes Help Meet Florida Building Code for Two 100% OAHU in South Florida

In a series of A/C unit retrofits in South Florida, HPT recently retrofitted two 70 ton 100% OAHU with wrap-around heat pipes at our manufacturing facility in Tampa FL. The rooftop units service a luxurious high-rise apartment building located in South Florida. Florida building code requires energy recovery effectiveness of 50% or higher in compliance with ASHRAE Std. 90.1, but makes an exception for wrap around heat pipes which can be applied at lower effectiveness values. Wrap-around heat pipes precool the air upstream of the CC and reuse the heat captured in the precooling process as free reheat downstream of the CC. 

For this installation, HPT retrofitted each 12,000 CFM rooftop unit with a 1-row wrap-around heat pipe system. Although a minimum 1-row system, the heat pipe brought the OA temperature down from 91°F db / 78°F wb to 85°F db / 76°F wb in a typical design day while removing 79,415 Btu/hr of the load of the CC. This reduced the cooling load of the HVAC equipment by 8% and provided 79,415 Btu/hr of reheat.
