Multi splits with water heating, heat recovery
MIDEA HAS CREATED a multi split system which combines heating, cooling, water heating and heat recovery.
The all year round heat pump solution was a joint project between Paolo Lorini, head of Midea RAC Design Milan (MRDM) and Matteo Nunziati, a top Italian interior designer.
Nunziati is considered one of the most tal- ented interior designers of his generation.
For Nunziati, a holistic design takes into account not only sustainability but also func- tionality and aesthetics. This has been incorpo- rated into Midea's new multi splits system with integrated water heating.
Lorini said most homes today are installed with several independent systems, with an air condi- tioner for the summer, floor heating for the winter, and a gas boiler for all-year water heating.
“This is inefficient, costs too much to run and maintain, and takes up a lot of home space,” he said.
"Midea has created something completely dif- ferent: we have integrated all the above systems into a multi-spilt solution that supports up to four indoor air conditioning units, capable of cooling and heating the space, and a water

heating module, all connected to a single out- door unit with heat recovery technology.”
In summer, free domestic hot water is avail- able when the air-conditioner is running, as its energy can be recovered and reused for water heating.
The system comes in two options for house- holds with different priorities. The model equipped with a hydro unit is designed for users who need both the space heating and hot water supply at no additional cost, while one has a coil water tank to allow for fast air cooling and heating while providing hot water the whole year.
Product guide to rooftop units
It is the first compendium of its kind developed by the rooftop industry.
THE EUROVENT PRODUCT Group has pub- lished its first guidebook on rooftop units.
The guidebook gives an insight into types, design, applications, operation, selection and maintenance of rooftop units.
The free guide is the first compendium of its kind developed by the rooftop industry.
Filip Konieczny, business development man- ager at FLOWAIR and chair of Eurovent’s prod- uct group for rooftop technology, said rooftop units are growing in popularity.
“The reason is their excellent ability to effi- ciently maintain Indoor Environmental Quality as well as thermal comfort,” he said.
“That's why rooftop units are successfully used in various applications. With this
Guidebook, we aim to share technical knowl- edge and market insights directly from industry experts.
“It is worth reading for anyone involved in the HVAC investment process. We are confident that it will help raise awareness of the benefits of rooftop units.”
Vice chair of the Eurovent group, Arel Arsoy, said rooftop units are an efficient solution not only for building cooling/heating loads, but also for ventila- tion and dehumidification purposes including free cooling capabilities in compact dimensions.
Eurovent, which represents more than 1,000 companies, is an industry association for Europe’s indoor climate, process cooling and cold chain companies.
