What is DMVHR?

Installing a ventilation system in the house is very important because the quality of life depends on it. Today, people try to use equipment with reduced energy and simultaneously achieve the highest quality of life. Fortunately, modern ventilation systems allow people to use less energy and get effective air conditioning. One of the latest developments that received many positive reviews among users is the Decentralised Mechanical Ventilation with Heat Recovery (DMVHR) system.

Its compactness and simple control mechanic make this system a nearly perfect solution for energy-efficient homes. Still, what this system is capable of? What benefits do you get when using it? What is a heat recovery system? How does it help in achieving appropriate air conditioning? Keep reading, as we will get all the questions answered.

What does dmvhr stands for?

Dmvhr stands for decentralised mechanical ventilation with heat recovery. This new technology could be implemented into existing houses or used in the new ones. It provides proper ventilation for the whole house as it’s inserted directly into the wall and is hygienically clean. Moreover, it has a low emission level, so that the system won’t be a problem for people with allergies.

Why is dmvhr advantageous for dwellings?

When choosing the best ventilation system for the house, people compare models to select the one that matches all the requirements. Since the decentralised ventilation system was released, it became a #1 choice for many customers. Still, why is dmvhr advantageous for dwellings?

Decentralisation. The technology easily integrates into your home ventilation system. Since it consists of several elements installed in each part of the apartment, you can control the fresh air supply for each room individually, making your living environment more comfortable.
Simple control. Users can manage their decentralised ventilation systems using voice assistants like Google Assistant or Amazon Alexa. Bluetooth control via smartphone could also be used to manage temperature and turn the system on/off.
Noiseless technology. Another reason why is dmvhr advantageous for dwellings is because this system doesn’t make noise. There are low-noise fans integrated into the construction, reducing the sound level. The decentralised ventilation system is a good choice if you have a baby sleeping or don’t want to be disturbed during work.
Improved air quality. The system effectively exchanges indoor and outdoor air, filtering out pollutants, balancing the humidity level, and adjusting the air temperature in a specific room.

Another advantage of this technology is that such a ventilating mechanism is energy efficient. The system uses less energy to warm the air, which means you will have lower heating bills.

How does an dmvhr unit work?

When answering this question, we should consider that there are two basic types of decentralised mechanical ventilation: the one with continuous operation and the other that works with reversing operation.

Continuous operation ventilation has a cross-countercurrent heat exchanger implemented in each unit. The units have two fans conveying the air simultaneously, bringing the fresh inside and moving the indoor air outside. The heat exchanger is placed between two air flows, recovering heat from the indoor air and transferring it to the supply air. Despite the ventilation continuing for a while, the heat level in the room remains high.

Reversing operation ventilation differs from the continuous mechanism as only one fan is inside. Two units that have constant communication are responsible for keeping the air change rate at the same level. One removes the stale air from the room, while the other makes the fresh air come inside. Units are connected to each other via the controller. They also have filters to keep the air clean and protect against noise that comes from the outside.

What is a heat recovery system?

A heat recovery system is a mechanical recovery system that operates between two air sources with different temperature levels. Its main goal is to balance the heat level inside the buildings, preheating or precooling the air that comes inside the room. The main advantage of this system is that it effectively uses the warmth that already exists in the air in each room.

Tips for choosing a decentralised ventilation system

When choosing a decentralised mechanical ventilation system with heat recovery, consider the characteristics of the dwelling. Homeowners should consider the building type and ensure they can implement specific electrical connections.

Also, it’s crucial to decide the places to install ventilation units. They should be placed at the top of the room because stale air usually accumulates there. Moreover, it’s essential to plan the placement of ventilating mechanisms to keep them away from sleeping areas even though these things are quiet.

Frequently asked questions about dmvhr

Maintaining such a mechanism yourself may be complicated even though you understand how it works. The best way to ensure the system works properly is to hire specialists who will change filters and conduct inspections to ensure nothing blocks the air path. It’s important to look for a specialist who understands how a decentralised ventilation system works and what should be done in case of an issue.

The main advantage is that this system is simple to install. You can place blocks in every room and do it quickly. All that’s needed is an electrical connection and a drilled hole in the wall. If you already have a centralised ventilation system installed in your apartment, you can combine them.

In a centralised ventilation system, all ventilating units are connected to the main block, supplying and extracting air like the arms of an octopus. Meanwhile, a decentralised ventilation system consists of multiple ventilation units installed in different parts of the house. All units are installed in pairs because one extracts the dirty air while the other supplies fresh air inside the dwelling. Moreover, such teams make the incoming air cooler or warmer depending on the inside temperature.

A decentralised ventilating system with heat recovery is an advantageous decision for everyone who wants to raise the quality of the air inside the apartment. Moreover, it’s a profitable investment as all modern systems reduce electricity usage.
