Midea MKD-500 — 2-pipe compact four-way cassette fan coil

Midea MKD-500 is a 2-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 850/730/600 m³/h airflow, 4.50/3.60/3.06 kW cooling capacity and 6.00/4.76/4.07 kW heating capacity. In the two-pipe arrangement, the same water circuit is used for seasonal cooling or heating. 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 95/53/42 W, sound pressure is 45/42/34 dB(A), and cooling-water flow is 0.77/0.61/0.53 m³/h. The water connection is G3/4, 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.
