It combines an indoor unit \u003cstrong data-start=\"1395\" data-end=\"1408\"\u003eKNSCB361A\u003c\/strong\u003e and an outdoor unit \u003cstrong data-start=\"1433\" data-end=\"1446\"\u003eKUSXB361A\u003c\/strong\u003e, with a nominal cooling capacity of \u003cstrong data-start=\"1478\" data-end=\"1492\"\u003e36,000 BTU\u003c\/strong\u003e, operation with \u003cstrong data-start=\"1544\" data-end=\"1552\"\u003eR-32\u003c\/strong\u003e refrigerant, \u003cstrong data-start=\"1572\" data-end=\"1588\"\u003eENERGY STAR®\u003c\/strong\u003e certification, and a design adapted for cold climates. The LG KSSCB361A technical sheet indicates a cooling capacity of 14,400 to 42,000 BTU\/h, a heating capacity of 16,000 to 42,200 BTU\/h, a SEER2 of 22.0, an EER2 of 13.0, and an HSPF2 of 10.3; diagrams on pages 2 and 3 also detail the dimensions and mounting points of the indoor and outdoor units.\u003c\/p\u003e\n\u003ch3 data-section-id=\"2b9dpv\" data-start=\"1984\" data-end=\"2055\"\u003eWhy a 3x3 cassette changes the experience in a large room\u003c\/h3\u003e\n\u003cp data-start=\"2057\" data-end=\"2491\"\u003eA ceiling cassette is not just for hiding the indoor unit. Its primary advantage is \u003cstrong data-start=\"2162\" data-end=\"2186\"\u003eair distribution\u003c\/strong\u003e. In an open-plan area, a wall-mounted unit can sometimes concentrate cooling or heating in a single zone, especially when the room is long, has many windows, or is divided by furniture. A four-way cassette installed in the right place, however, allows for more balanced air distribution.\u003c\/p\u003e\n\u003cp data-start=\"2493\" data-end=\"3024\"\u003eIn a commercial space on the \u003cstrong data-start=\"2524\" data-end=\"2536\"\u003eSouth Shore\u003c\/strong\u003e, for example, a frequent need is to air condition a reception area without directing cold air directly onto the counter, customers, or employees. A well-positioned 3x3 cassette can reduce this problem, as the airflow is distributed in multiple directions. In an office in \u003cstrong data-start=\"2818\" data-end=\"2827\"\u003eLaval\u003c\/strong\u003e or a professional space in \u003cstrong data-start=\"2862\" data-end=\"2874\"\u003eMontreal\u003c\/strong\u003e, this approach also helps to limit common complaints: one person is too cold near the unit, while another area remains too hot.\u003c\/p\u003e\n\u003cp data-start=\"3026\" data-end=\"3427\"\u003eThe recessed format is also appreciated in projects where aesthetics matter. Suspended ceilings, conference rooms, retail stores, and healthcare spaces benefit from keeping walls clear. For property owners, this often facilitates future space planning, as the HVAC equipment does not dictate the placement of furniture, displays, or partitions.\u003c\/p\u003e\n\u003ch3
