STjh over-under heat-pipe energy recovery unit with stacked air passages and vertical connecting tubes on white.

STJH-HEAT-PIPE-ENERGY-RECOVERY-OVERUNDER

Heat-Pipe Energy Recovery Unit Over-Under Single-Season

A stacked-air-stream thermosiphon that transfers heat strongly in one selected seasonal direction.

Passive vertical thermosiphon
Single-season recovery bias

Introduction de produit

This heat-pipe unit places one air stream above the other and uses vertical 1/2 in copper tubes as a passive thermosiphon. Gravity-assisted liquid return creates strong transfer in one selected direction, so the circuit is optimized for either a dominant heating or cooling season rather than equal bidirectional duty. The stacked housing is especially suitable where supply and exhaust ducts already run over and under each other.

Key Features

Gravity-assisted circulation

Vertical tubes return condensed working fluid to the evaporator without a mechanical pump.

Stacked duct integration

One coil face sits in each over-under air stream across a sealed partition.

Strong one-way recovery

Orientation is selected around the dominant annual heating or cooling benefit.

Applications

For clean facilities with stacked ducts and a dominant heating or cooling season requiring separated-stream passive recovery.

Solutions for Your Application

The thermosiphon is selected for the wrong seasonal heat-flow direction.Define the dominant recovery mode and place the evaporator below the condenser for that condition.

Field tilt or casing settlement disrupts gravity return.Provide level structural support and verify vertical tube orientation during commissioning.

Options disponibles

Specify dominant season, supply and exhaust positions, rows, fin density, casing, coatings, partition, bypass and freeze protection.
