591 Cooling and heating for small residential buildings Daikin has been providing heat pumps from its BLUEVOLUTION range as an ideal solution for various residential projects. One of the most recent installations took place in Porto, Portugal, where two EWYT-CZ units were installed, delivering a total cooling and heating capacity of 21 kW each. These systems demonstrate Daikin’s commitment to combining energy efficiency with reliable performance in residential settings. The challenge The goal of the project was to provide the end customer with a versatile solution capable of delivering both heating and cooling according to seasonal needs, as well as hot sanitary water. The system was designed to ensure maximum reliability, high energy efficiency, and low operating costs. The solution The new R-32 Small Inverter Chiller has once again proven to be an excellent solution for residential projects, demonstrating the versatility of Daikin’s product portfolio, which can meet the needs of installations ranging from large stadiums to individual homes. For this project, Daikin supplied two units in the heating version, each delivering 21 kW to comfortably meet the system’s capacity requirements while achieving market-leading energy efficiency for this product segment. The R-32 Small Inverter Chillers were integrated into a system designed to provide both heating and cooling to indoor fan coils, as well as hot sanitary water, depending on seasonal needs. This solution was particularly valuable for the project due to its modern design, which maximizes efficiency through fully optimized inverter units and the use of the low-GWP R-32 refrigerant. Reliability was further guaranteed by Daikin’s extensive experience in developing and deploying R-32 technology, ensuring consistent performance and long-term dependability. Daikin’s References
