FAQ

1. What is a honeycomb heat storage core?

A honeycomb heat storage core is the key thermal storage component used in residential heat recovery ventilation systems to recover and reuse indoor thermal energy.

2. How does a honeycomb heat storage core work?

It stores heat or cooling energy from exhaust air and transfers the stored energy to incoming fresh air after the airflow direction reverses.

3. What are the advantages of a honeycomb heat storage core?

It offers high heat recovery efficiency, low airflow resistance, compact construction, quiet operation, and long service life.

4. What materials are commonly used?

Common materials include ceramic honeycomb, cordierite, mullite, and other high heat-capacity ceramic materials.

5. Where is a honeycomb heat storage core used?

It is commonly used in wall-mounted fresh air ventilators, regenerative ventilation units, HRV systems, ERV systems, and residential ventilation equipment.

6. Why does the honeycomb structure improve heat recovery?

Its large surface area enhances heat transfer while maintaining low airflow resistance.

7. Can a honeycomb heat storage core reduce energy consumption?

Yes. By recovering heat or cooling energy from exhaust air, it helps reduce heating and cooling loads.

8. Does a honeycomb heat storage core require maintenance?

Routine cleaning of air filters and periodic inspection of the heat storage core are recommended according to the equipment manufacturer's maintenance guidelines.

9. What is the difference between a honeycomb heat storage core and an HRV core?

Honeycomb heat storage cores are commonly used in regenerative ventilation systems with alternating airflow, while many HRV systems use plate-type heat exchangers.

10. Are custom honeycomb heat storage cores available?

Yes. Manufacturers can provide customized dimensions, ceramic materials, cell densities (CPSI), airflow capacities, and installation configurations.
