MHI Thermal Systems Adds New KXZ3 Series of Building-use Multi-Split Air- Conditioners Adopting R32 Refrigerant
— Launching 22.4 kW ~ 33.5 kW Models in Overseas Markets–
– Building-use air-conditioner lineup is broadened with designs utilizing R32 refrigerant with GWP near one-third of earlier designs
– New series to be introduced in Europe this summer season, followed by Australia, New Zealand and Turkey
TOKYO, Apr 9, 2024 – (JCN Newswire) – Mitsubishi Heavy Industries Thermal Systems, Ltd. (MHI Thermal Systems), a part of Mitsubishi Heavy Industries (MHI) Group, has actually begun mass production of the “KXZ3 Series” of building-use multi-split air-conditioners for its around the world markets. The recently included lineup, which embraces the R32 refrigerant, is readily available in 3 designs: 22.4, 28.0 and 33.5 kW. By integrating specific systems, an optimum 100.05 kW can be attained to accommodate a vast array of abroad requirements. The brand-new series will be released in the European market this summer season, to be followed by succeeding launches in Australia, New Zealand and Turkey.
KXZ3 Series
The KXZ3 Series assists alleviate ecological effects through adoption of the R32 refrigerant having a Global Warming Potential (GWP) (Note1) of 675, which is approximately one-third the level of the R410A refrigerant (GWP 2,090) utilized in earlier designs. The brand-new series likewise increases energy cost savings through a near 18% enhancement in seasonal energy effectiveness ratio (SEER) (Note2), a sign of an air-conditioner’s energy performance. Effectiveness improvement owes to the adoption of a brand-new kind of compressor fit to the R32 refrigerant plus a brand-new air circulation course style, consisting of a freshly set up impeller and bellmouth.
The KXZ3 Series likewise includes a brand-new outside style with blue decoration, while the needed setup area has actually been cut some 28% from the previous designs thanks to adoption of a single-fan structure and a compact yet extremely effective heat exchanger with a lowered size copper tube. Freshly included functions consist of: 1) Variable Temperature & & Capacity Control +, which immediately changes for a perfect balance in between energy conserving efficiency and indoor convenience with the automated change of refrigerant pressure according to the indoor and outside temperature levels and 2) “hot gas bypass defrost,” an operating mode that eases the fall in indoor temperature level typical to earlier thawing operation (Note3). Under particular conditions, the KXZ3 Series, like other items embracing the R32 refrigerant, likewise needs extra security functions in order to please European security requirements. MHI Thermal Systems has a lineup of devoted security gadgets. Amongst them is a shutoff valve that can be linked to numerous indoor systems. In these and other methods, the KXZ3 Series has specs allowing consumers to suppress preliminary setup expenses.
Moving forward, MHI Thermal Systems will continue making favorable contributions to the broadening worldwide mission to attain decarbonization through arrangement of options in its air-conditioning service, consisting of packaged and building-use air-conditioners for abroad markets that all at once attain both energy cost savings and indoor convenience.
