Recently, ventilation systems with heat recovery have gained many new supporters from different parts of the world. Ease of installation and operation, high efficiency, and environmental friendliness have contributed that such devices have actually become a product of mass consumption.
PRANA recuperators/ decentralised MVHR, designed on the basis of a copper heat exchanger, have long won the favour of the audience and are very popular in more than 42 countries. After all, the philosophy of manufacturing an innovative Ukrainian ventilation system has always been based on maximum comfort and care for the consumer’s health around the world.
Along with that, today the ventilation equipment market offers a wide range of heat exchangers of various types and shapes made of different materials: cellulose, aluminium, ceramic, and copper. So why copper?
We will try to answer the frequently asked questions of customers in this article.
The copper heat exchanger installed in the PRANA recuperator/ dMVHR provides high recuperation efficiency among analogues, keeping up to 96% of heat and coolness in the premise. This is due to the high coefficient of thermal conductivity of copper among other materials, the design of the heat exchanger, the heat exchange area, etc. For example, the coefficient of thermal conductivity of copper is 401 (W/m*K), aluminium – 200-236 (W/m*K).
Such a device ensures efficient operation, and necessary air exchange creates and maintains a healthy microclimate of rooms of various types and purposes.
Along with a high coefficient of thermal conductivity, copper has additional advantages – natural antiseptic properties and preservation of the natural composition of the air. It has been proven that copper has long been famous for its antibacterial properties because the risk of bacteria and viruses multiplying on the copper surface is reduced. It is not for nothing that this material was also used for medical purposes, where there was a danger of the spread of infectious diseases.
An additional advantage of the copper heat exchanger is the high efficiency of recovery of both heat and cold (during indoor air conditioning operation).
