The development: the s modular system The tube, a well-known component for LUNOS clients, can take in a wide range of technology. Meanwhile there are five different ventilators which can operate in this tube. Suitable for redevelopment and new construction, the series is now even more appealing. Each fan consists of four optional components: insert, tube, inside panel and outside grille. You can select these in line with the specific requirements of your project.

The ones we are really impressed with will make it here to our product of the month feature. Today we look at a new solution for changing the air in your home while maintaining excellent energy efficiency in heating. Heat Recovery Ventilators HRVs are an essential component of any air-sealed high performance home, bringing in fresh air and removing moisture. An HRV uses the heat in stale exhaust air to warm incoming fresh air. Until now, this has meant a centralized heat transfer core and a network of ducts feeding and drawing air throughout the home.

With Lunos wall insert air exchangers that is no longer the case. Below is a video from the manufacturer for a better understanding of how they work. Consequently, there is no need for ductwork or reserving space in your mechanical room for an air change system. The heat recovery is provided by a ceramic core, which is heated by exhaust air, and incoming air is warmed as it passes through the core. The cycle is reversed about every 90 seconds to heat and continually extract heat from the core.

According to European test standards the manufacturer claims to its efficiency is No need to provide space in the mechanical room or install a system of distribution ducts and air returns. Higher quality filters are available MERV , which can prevent pollen and dust from contaminating indoor air. Energy efficiency: The system has a high heat recovery, and performance is not dependant on the quality of duct installation.

Moisture management. The system is capable of exchanging heat and humidity. Thus, in the manner of an ERV Energy Recovery Ventilator , it helps to maintain the relative humidity of the air inside the house. In addition, frost problems are avoided in the device thanks to the frequent reversal of the direction of airflow.

Our hesitations: Originally we were a bit concerned with the relatively high cost of the system. However we recently installed some and this seems to be sufficiently offset by the absence of a bill for installing duct work. Your air exchange system is just such a thing. We will be happier when there are more of them out there so their performance can be better measured.

By multiplying the openings, it also increases the risk. This is one of the points of quantifying the actual energy efficiency of the product. Bathroom fans and stove hoods can be a problem in an airtight house due to the depressurization they can cause, and possibly affecting their operation.
