Samsung Electronics said on the 27th it has begun a demonstration of its high-efficiency heat pump heating and cooling system, EHS All-in-One, in apartment and other multifamily housing environments. The project will verify whether a single system can provide cooling while replacing the heating and hot water functions of existing gas boilers.
Samsung Electronics recently installed EHS All-in-One at the housing performance research center of Samsung C&T in Yongin, Gyeonggi Province. In an environment configured the same as an actual apartment, it will test ▲ heating and cooling and hot water performance ▲ energy efficiency ▲ power consumption ▲ noise ▲ user convenience. Samsung Electronics plans to use the data secured through the demonstration as basic materials for the deployment of heat pumps for multifamily housing and the development of related products.
The demonstration uses the EHS All-in-One model that Samsung Electronics sells in Europe. With a single outdoor unit, it supports both the air-to-air (A2A) method, which cools air directly, and the air-to-water (A2W) method, which heats water to provide floor heating and hot water.
In Korea, residential heat pumps mainly provide heating and hot water using the A2W method, requiring a separate air conditioner for cooling. EHS All-in-One integrates air cooling, floor heating, and hot water into a single system.
It also applies heat recovery technology that uses waste heat generated during cooling for hot water production. Under Samsung Electronics' test conditions, it utilized more than twice the thermal energy compared with existing methods. As the refrigerant, it uses R32, which has a global warming potential (GWP) about 68% lower than R410A, commonly used in conventional cooling equipment.
Lim Seong-taek, executive vice president of the DA Division at Samsung Electronics, said, "This demonstration is a project to verify whether heat pumps can practically replace existing gas boilers in actual multifamily housing environments," and added, "Based on the data we secure, we will expand technology development and deployment for the transition to electricity-based heating and cooling in multifamily housing."
