The present invention relates to a compact air conditioning device for a railroad equipment house or highway traffic control device. The device is primarily comprised of a housing with an interior space that preferably houses at least one air-conditioning unit with multiple features. A supply grate in the front wall of the housing can be routed into the equipment house such that the air-conditioning unit delivers cool air into the equipment house. The operation of the air-conditioning unit may be controlled by a remote or automatically controlled via at least one sensor. The air-conditioning unit may further be powered by at least one solar panel.

A window type air conditioner includes an indoor heat exchanger, an outdoor heat exchanger and a motor disposed in the shell. Rotating shafts at two ends of the motor are provided with an indoor fan and an outdoor fan. A thermal insulation partition is disposed on a bottom plate of the shell and divides the shell into an indoor side and an outdoor side. The thermal insulation partition includes a front clapboard fixed on the bottom plate of the shell and a thermal insulation volute disposed on the front clapboard. The indoor heat exchanger and the indoor fan are located in the thermal insulation volute. An integrated bracket is provided with a first mounting part for mounting and fixing the outdoor heat exchanger, a second mounting part for mounting and fixing the motor, and third mounting parts for connecting and fixing the front clapboard.

Provided is an air conditioner. The air conditioner comprising a housing having an inlet and an outlet, a fan in the housing to suck in air through the inlet and discharge air through the outlet, and including a plurality of fan blades with an installation space between two fan blades of the plurality of fan blades, a fan driver coupled to an end of the fan by a fastener, to drive the fan, wherein the installation space is positioned to allow the fastener to pass through the installation space to couple the fan driver to the fan, and a stabilizer including a body having at least a portion extending along the fan at a first distance from the fan, and so as to not be over the installation space as the fan rotates, and a modifier extending along the fan at a second distance, which is greater than the first distance, from the fan, and so as to be over the installation space for at least part of a full rotation of the fan as the fan rotates.

The object of this invention is a ventilation duct unit (1), which comprises an inlet (2), an outlet (3), a flow channel (4), which extends from the inlet to the outlet, and which is delimited by a wall (5) between the inlet and the outlet, a closing part (6), which is arranged into the flow channel, and which in open position enables flow in the flow channel, and in closed position prevents flow in the flow channel, closing member (12), which as a response to detecting fire, sets the closing part (6) to a predetermined position, and an actuator (8), which moves the closing part (6) between open and closed state in order to achieve flow defined for the actuator (8) in the flow channel. In order to utilize the ventilation duct unit for controlling fire situations and sound dampening, the ventilation duct unit further comprises insulation material (14), part of which is fireproof, and which surrounds the wall (5) of the flow channel and isolates the surrounded part of the wall of the flow channel from its surroundings, and holes (18) arranged in the surrounded part of the wall of the flow channel (4), which dampen sound by leading the medium flowing in the flow channel to be in contact with insulation material (14).
