Problems solved by technology

However, the existing terminal indoor unit is controlled separately from the main unit. If the user only closes the fan coil unit but not the main unit, although the cross-flow fan blades in the indoor unit stop running, the cooling water inside the heat exchange coil continues to flow, resulting in coil failure. The surface of the tube is prone to cold accumulation, resulting in a large amount of condensed water on the heat exchange coil, which is likely to cause water blowing when the user starts to use it next time

Embodiment Construction

[0022] Embodiments of the present invention are described in detail below in conjunction with accompanying drawings:

[0023] Such as figure 1 , figure 2 As shown, a terminal indoor unit of a commercial air conditioner includes a housing, a heat exchange coil 1, a cross-flow fan 2 and a control circuit. It has a water inlet and a water outlet that communicate with the outside world; in this embodiment, an electric water valve 7 is provided on the aforementioned water inlet and water outlet at the same time. The electric water valve 7 is a three-way electric valve that can simultaneously control the water inlet The on-off of the water circuit in the water end and the water outlet end, the electric water valve 7 is located in the housing and electrically connected with the control circuit. Of course, the three-way valve can also be replaced by two electric water valves installed at the water inlet and water outlet respectively, or only electric water valves are designed on th...

Abstract

The invention discloses a commercial air conditioner terminal indoor machine, which comprises a shell, a heat exchanging pipe coil, cross-flow fan blades and a control circuit, wherein the heat exchanging pipe coil and the cross-flow fan blades are arranged inside the shell, and the heat exchanging pipe coil is provided with a water inlet end and a water outlet end which are communicated with the exterior; and the water inlet end and / or the water outlet end are / is provided with an electric water valve, and the electric water valve is arranged inside the shell and is electrically connected with the control circuit. Due to the adoption of the commercial air conditioner terminal indoor machine, the water blowing phenomenon produced when the air conditioner works at the next time can be effectively alleviated, the influence of the modified structure on the appearance of the indoor machine can be avoided, and the indoor decoration is free from being damaged.

Description

technical field [0001] The invention belongs to the air field and relates to a commercial air conditioner terminal indoor unit. Background technique [0002] Among the terminal indoor units of commercial air conditioners, surface-mounted wall-mounted indoor units have always been popular among end products. The indoor unit can be directly hung on the surface of the indoor wall to save indoor space and environment. Its appearance can be integrated with the interior decoration. One. However, the existing terminal indoor unit is controlled separately from the main unit. If the user only closes the fan coil unit but not the main unit, although the cross-flow fan blades in the indoor unit stop running, the cooling water inside the heat exchange coil continues to flow, resulting in coil failure. The surface of the tube is prone to cold accumulation, resulting in a large amount of condensed water on the heat exchange coil, which is likely to cause water blowing when the user start...
