5.galvanized sheet

Hrv core

Cross and Counterflow heat recovery exchanger HRV core as they are also known, are an extremely effective and low-cost way of reducing the heating or cooling loads on the treatment of process air and air conditioning systems. A reduced heating or cooling load means lower energy bills and carbon emissions.Air Plates use the exhaust air to pre-heat or pre-cool the in-coming supply air,without the two air streams ever mixing.

Hrv core

Working principle:

Cross-counter flow is higher efficiency energy recoverer,part of two air sreams cross flow, and part of counter flow, combined the cross flow heat exchanger and counter flow heat exchanger two ways heat transfer, realized the energy recovery of exhaust air.

Features of Cross and counter flow plate heat exchanger

1. Aluminum foils cross flow sensible heat exchanger

2. Heat recovery efficiency up to 75%

3. 2-side press shaping, double folded edge.

4. Resistance of pressure difference up to 2500Pa

5. Under pressure of 700Pa, air leakage less than 0.6%

Material type of Cross and counter flow plate heat exchanger

Normal series (standard type)

Heat exchanger is made of pure aluminum foils, with galvanized end cover and aluminium alloy wrap angle. Max. air temperature 100°C, it is suitable for most of the occasion. 

Blue coating series ( Anti-corrosion type)

Heat exchanger is made of pure aluminum foils cover by special anti-corrosion material, with galvanized end cover and aluminium alloy wrap angle. it is suitable for the corrosive gas occasion.

Epoxy series (high temperature type)

Heat exchanger is made of pure aluminum foils, with galvanized end cover and aluminium alloy wrap angle. Sealing material is special and allow the Max. air temperature to be 200°C, it is suitable for special high temperature occasion.

INSTALLATION NOTES

Condensing water pan

When designing heat recovery functional section in air handling unit, under the heat exchanger should add the condensing water pan, in case of disorderly flow of condensing water

Heat exchanger vertical installation

When outdoor temperature is lower than indoor temperature, during heat exchanging if RA temperature is low enough (relative humidity 100%) then condensing water will come into

being, once there is condensing water, heat exchange area inside heat exchanger is decreased, efficiency become lower and pressure drop increased, in order to eliminate the condensing

water in time, heat exchanger vertical installation like the picture below is the best choice.

Hrv core

Installation

Pattern 1 and 2, to increase the heat exchange area, suitable for occasions requiring higher heat recovery efficiency,
however, air resistance will increase accordingly.

Pattern 3 and 4, to increase the front face area, suitable for occasions requiring large airflow, both air resistance and

heat recovery efficiency remain stable.

Pattern 5, to increase both front face area and heat exchange area, suitable occasions requiring higher heat recovery

efficiency and large airflow.

Applications

Installed in air handling unit

AIR-ERV plate heat exchanger can be used in the air handling unit (AHU) as a main part of the heat recovery section, and the bypass can be built in when required.

Hrv core

Installed in ducts

It can also be installed in the ducts of ventilation system as a main part of the heat recovery section. The installation is very flexible.

FAQ

What's the difference between sensible heat exchanger and total heat exchanger?
1.Sensible heat exchanger is made of Aluminium foil,total heat exchanger is made of paper.
2.Sensible heat exchanger only exchange heat,total heat exchanger can exchange both heat and humidity.
3.Sensible heat exchanger has longer life and higher pressure-resistance than total total exchanger.
   Because the paper heat exchanger are easy to be corroded by the water and dust in the air.The vent of 
   total heat exchanger is easy to be blocked and hard to be cleaned.This will lead to bad ventilated effect.
