Ventilation Types for OTR Microwaves
When it comes to venting, OTR microwaves typically offer two primary options: external venting and recirculating venting. Understanding these options is essential for determining the best installation method for your kitchen.
External Venting
External venting, also known as ducted venting, is where the air is expelled outside of your home. This method is considered the most effective for removing smoke, steam, and cooking odors.
Benefits of External Venting:
- **Improved Air Quality**: By venting outside, the moisture and odors are eliminated from the kitchen.
- **Better Performance**: External vents typically provide better airflow, enhancing the efficiency of both your OTR microwave and range.
To install an externally vented OTR microwave, you will need to connect a duct system that leads from the microwave to a wall or roof vent. This can involve some additional home modification but is worth it for the benefits of enhanced airflow and air quality.
Recirculating Venting
In many situations, especially in apartments or homes where outside venting isn’t feasible, a recirculating venting system is a suitable alternative. This method filters the air and returns it back into your kitchen.
Features of Recirculating Venting:
- **Carbon Filters**: Recirculating models often come equipped with carbon filters that help absorb odors and smoke.
- **Ease of Installation**: They are easier to install since they don’t require ductwork to the outside.
While recirculating ventilation may be less effective than external venting in removing heat, smoke, and odors, it’s a practical solution for many homeowners.
How OTR Microwaves Vent: The Mechanics
Both venting systems rely on a similar mechanical design and process to effectively circulate air. Understanding the mechanics involved can help you choose the right system for your needs and ensure that your appliance operates at peak efficiency.
Venting Mechanism
Regardless of the venting method, OTR microwaves incorporate powerful fans that help move air through the unit. Here’s a step-by-step overview of how this process works:
- Air Intake: When the microwave is turned on, it pulls in air from the kitchen through vents located at the front or bottom of the unit.
- Filtration (if applicable): In recirculating models, the air passes through a series of filters. These may include:
- Grease filters: Trap grease particles emitted during cooking.
-
Charcoal filters: Absorb odors from the air.
-
Air Movement: After filtration, the air is propelled by an internal fan. This fan can usually be set to different speeds based on the intensity needed for ventilation.
- Discharge:
- In external venting, the filtered air is expelled outside through the ductwork.
- In recirculating venting, the cleaned air is channeled back into the kitchen.
Understanding this sequence can assist you in troubleshooting any issues you may face while using your OTR microwave.
Choosing the Right Venting Option
Selecting the right venting option depends on various factors including your kitchen layout, homeowner regulations, and personal preferences. Here’s what you should consider when making a choice.
