The utility model discloses owing to adopted above technical scheme, make it have following beneficial effect:

1. in high-temperature operation environments such as steel plants, coke plants and the like, traveling cranes can operate in certain special areas (such as areas of electric furnaces, steel furnaces and the like) at variable times, the environment temperature is very high and generally exceeds 75 ℃, the traveling cranes leave the areas after the operation is finished, and the environment temperature is suddenly reduced to be 40 ℃ at the lowest. When the high-temperature air conditioning unit is in the situation that the environmental temperature changes repeatedly for a long time, the condensation pressure of the air conditioner changes rapidly and repeatedly, at the moment, the damage rate of the scroll compressor of the traditional high-temperature air conditioning unit using the scroll compressor is obviously improved, and the damage rate of the semi-closed compressor of the high-temperature air conditioning unit using the semi-closed compressor is obviously lower than that of the scroll compressor, so that the high-temperature air conditioning unit using the semi-closed compressor can better ensure the refrigeration effect compared with the traditional high-temperature air conditioning unit using the scroll compressor;

2. in high temperature operation environment such as steel mill, coke-oven plant, some environmental condition can be more abominable, if: under the conditions that the compressor is damaged due to the fact that air contains a large amount of various dust, the environment working condition is changed repeatedly and the like, the high-temperature air conditioning unit using the semi-closed compressor has longer service life and better refrigeration effect compared with a high-temperature unit using a scroll compressor;

3. in high temperature operation environment such as steel mill, coke-oven plant, use the traditional high temperature air conditioning unit of scroll compressor, in case the compressor breaks down, according to the nature of compressor, only can change the compressor, and change the compressor and need move the fire welding, and have strict requirements to moving the fire in some steel mills for the maintenance is very inconvenient when. The high-temperature air conditioning unit using the semi-closed compressor perfectly solves the problems and is easy to maintain and overhaul.

4. The high-temperature air conditioning unit using the semi-closed compressor can realize various air supply forms including but not limited to lower air supply and lower return air, lower air supply and side return air, side air supply and lower return air and the like as an integral air conditioner, can be changed according to the actual requirements of customers, and can meet various different requirements as far as possible; the semi-closed compressor can also be used as a split air conditioner, is placed in an outdoor unit and is connected with an indoor unit through a connecting pipe to perform refrigeration.

5. The air conditioning unit using the semi-closed compressor has the advantages of simple principle, easy realization and obvious effect, can completely replace the traditional high-temperature air conditioner using the scroll compressor in severe environment, is widely applied, is convenient and fast to maintain, can be produced and applied on a large scale, and has good economic benefit.
