Built-In Cabinet with Components Installed with Fireplace
The customer has a decent amount of equipment installed in a built-in cabinet.
A built-in cabinet usually does not make for easy cooling solutions - they are very attractive and an easy way to conceal components, but usually venting the systems leads to various challenges. In this case though, there is a reason that we focused on the fireplace.
Solution to the Situation:
There a few approaches to this situation. The easiest is to potentially use one or two HiFlo Lite units, one installed in the top of the cabinet over each 'bay' of components. The grill can be painted to match the cabinet color but this will restrict use of the top of the cabinet.
The other option, which this customer selected, was to vent into the fireplace box. Prefabricated fireplaces have a lot of airspace in them so venting into them works just fine. This way it is a very inconspicuous installation and it would require the use of a HiFlo Lite unit but the area between the two bays needs to have open airflow so air from all components can be vented appropriately. If the customer continued to have issues, then the use of Single and/or Dual Fan Cooling units would be appropriate. One placed on the heat producing components would eliminate any heat pockets and facilitate effective venting.
The proper thing to have done in this situation would have been to install a vent in the wall behind the built-in cabinet and best case scenario, this vent would connect to a return vent in the HVAC system. By installing a standard 4x8 register box, our HiFlo Basic System can be used to very effectively cool the system.
