The invention discloses an upright surface-mounted improved pipeline and surface cooler type
fan coil unit, comprising a shell, bases, a mounting plate I, a mounting plate II, an air inlet plate, an air outlet plate, an electric controller, a
surface cooling device, an improved pipeline structure, a motor device, a
condensed water disc, an outside
pipe water disc and a wiring terminal; the motor device consists of a motor, a motor mounting plate, a
coupling rod and a fan, the
surface cooling device consists of a surface cooler, water outlet pipes and water inlet pipes, two groups of the water inlet pipes and two groups of the water outlet pipes are arranged, each group of water outlet pipes is connected to the surface cooler by a
pipe, each group of water inlet pipes is connected to the surface cooler by three pipes, the improved pipeline structure consists of water inlet pipelines, water outlet pipelines, a water
inlet valve and a water outlet valve, and two groups of the water inlet pipelines and two groups of the water outlet pipelines are arranged. The water inlet and outlet pipes are provided with the water
inlet valve and the water outlet valve, the valves are controlled by the electric controller to be opened and closed so as to control a
water flow volume, and the connecting
pipe quantity of each group of the water inlet and outlet water pipes can improve water outlet efficiency and water inlet efficiency and improve refrigerating or
heating efficiency.
