Intermediary's water outer tube 2 in the duct type heat exchanger unit at the two ends of pipe 5 is still through the intermediary's water overcoat for being provided with flange connector 4
Pipe connected pipe 3 is connected, i.e., using intermediary water overcoat pipe connected pipe 3 across each node, it is ensured that in the duct type heat exchanger
The circulation of intermediary's water is unimpeded；The length of the supplying drainage 5 is calculated according to project reality and determined.
Inventive pipeline formula heat exchanger mounting means can determine according to actual conditions, for plumbing standpipe when can be with
Right angle setting, for plumbing horizontal pipe when can be horizontally mounted；Installation site can be architecture pipe well inside or
Inside furred ceiling.The specification of duct type heat exchanger depends on plumbing inner tube 1, size according to Project design plumbing inner tube 1 and
Spacing between the tube wall of intermediary water outer tube 2 and the tube wall of plumbing inner tube 1, calculates the diameter for determining intermediary water outer tube 2.Possess
The pipeline section of pipe laying formula heat exchanger condition, its minimum diameter of plumbing inner tube 1 (if caliber is too small, is produced not less than DN50
Processing has no problem, but residual heat resources are limited, does not have recovery value, and mostly branch pipe, and installing space is limited).Outside intermediary's water

Plumbing is normally circulated by middle plumbing inner tube 1, and intermediary's water is in intermediary water outer tube 2 and intermediary's water overcoat
Circulated in pipe connected pipe 3, the energy in plumbing is transmitted to intermediary's water by tube wall.During cooling condition, the waste heat elder generation of building interior
Be conducted to intermediary's water, heat be then transferred to by intermediary's water by plumbing again, the temperature of plumbing during conveying by
Edge up height, so as to realize reducing the effect of building interior temperature, reaches refrigeration；During heating condition, the heat elder generation of plumbing
Intermediary's water is conducted to, the heat that intermediary's water is obtained is used to heat or heating domestic hot water after being absorbed by external equipment, plumbing
After heat is conducted to intermediary's water, temperature is gradually reduced.Intermediary's water is constantly followed between external equipment and duct type heat exchanger
Ring, completes transmission of the energy in low-temperature heat source (plumbing) and between external equipment.Being raised and lowered for temperature does not influence plumbing
Normal conveying and use, just with the duct type heat exchanger reclaim plumbing in energy.

It is bigger.In the course of conveying of plumbing, using duct type heat exchanger, can be recovered energy during conveying, reach one
Lift two effects for obtaining.
Cooling condition is preferably used in for running water, the waste heat of building interior is conducted to running water, raises its temperature, subtracted
Energy consumption when few user heats, equivalent to building waste heat come pre- hot tap-water.So while refrigeration, while heating, reaches one
Lift two functions of obtaining；If being used for heating condition, it is necessary to be absorbed heat from running water, make the reduction of its temperature, energy when user heats
Consumption increased, so the economy that the energy for absorbing running water is used for heating condition is not high.For reclaimed water, sewage, rainwater, reclaim
Energy is all possible for heating, freezing, providing domestic hot-water, because the change of water temperature does not influence follow-up use or discharge.
