Amid the trend of decarbonization in the building sector, work to secure basic data for the transition to electric heating in multi-unit housing has begun in earnest.

Samsung Electronics announced on the 27th that it has installed the 'EHS All-in-One' at the Samsung C&T Residential Performance Research Center in Yongin, Gyeonggi Province, and started a demonstration.

We plan to comprehensively verify heating, cooling, and hot water performance, energy efficiency, power consumption, noise, and ease of use in an environment designed to be identical to an actual apartment.

The secured data will be used as basic data for the future distribution of heat pumps in multi-unit housing.

The 'EHS All-in-One' applied in this demonstration is a product currently being sold in the European market.

It is a structure that simultaneously implements air cooling (Air to Air, A2A) and floor heating/hot water supply (Air to Water, A2W) with a single outdoor unit.

Existing domestic residential heat pumps primarily used the A2W method to provide only floor heating and hot water, requiring a separate air conditioner for cooling.

The company explained that 'EHS All-in-One' is characterized by integrating the two methods into a single system.

waste heat generated during the cooling processIt is also equipped with 'Heat Recovery' technology that recycles heat for hot water supply.

The company stated that it can reduce power consumption by utilizing the heat released during summer cooling to produce hot water, and can utilize more than twice the thermal energy compared to existing methods.

In addition, R32 refrigerant, which has a global warming potential (GWP) about 68% lower than the existing R410A refrigerant, was applied.

“This demonstration goes beyond verifying product performance and is a project to verify whether heat pumps can practically replace gas boilers in multi-unit residential environments,” said Lim Sung-taek, Vice President of Samsung Electronics’ DA Business Division. “Based on the data obtained, we plan to continuously expand the development and distribution of heat pump technology for the transition to electric-based heating and cooling and carbon neutrality in the building sector.”
