Midea MKD-300S — 4-pipe compact four-way cassette fan coil

Midea MKD-300S is a 4-pipe compact four-way cassette fan coil installed within a suspended ceiling as a hydronic room terminal. At high, medium and low fan speeds it delivers 510/440/360 m³/h airflow, 2.50/2.20/1.76 kW cooling capacity and 3.70/3.29/2.92 kW heating capacity. The four-pipe arrangement separates chilled- and hot-water circuits, allowing different zones to request heating and cooling at the same time. The 647×50×647 mm panel distributes air around the perimeter for even coverage of the occupied zone. The 261 mm body height suits shallow ceiling voids, and the built-in drain pump provides a 500 mm lifting head.

Power input across the three speeds is 50/40/30 W, sound pressure is 36/33/28 dB(A), and cooling-water flow is 0.43/0.38/0.30 m³/h. The water connection is soyuq G3/4, isti G1/2, the drain outlet is OD25, and the unit body measures 575×261×575 mm. It can serve residential, hotel, office and commercial zones when selected against the calculated room load, water temperatures and piping arrangement. This is not a self-contained refrigerant split air conditioner; operation requires a chiller or a suitable hot- and chilled-water source.
