Description
(1) technical field
The utility model relates to a kind of performance testing device of air-conditioning, particularly relates to a kind ofly in high temperature operation occasions such as metallurgy, chemical industry, is installed in the air conditioner refrigerating performance testing device in the driving.
(2) background technology
High temperature bridge crane air conditioning unit is the artificial atmosphere unit on a kind of travelling facility that is used for high temperature operation occasions such as metallurgy, chemical industry.Can be divided into monoblock type and split type two kinds according to structure.
Monoblock type is installed on the top or the side wall of driving inner space usually, by wind channel cooling air is introduced the driving inner space.The driving inner space generally can be divided into cab part, electric room part and fluid pressure type part, but divide howsoever, these three zones all need to cool off, and the air after the circulation of driving inner space picks out the return air inlet of guiding bridge crane air conditioning into by air-return duct, finishes one and takes turns air circulation.Split air conditioner drags with a machine one and is example, is made up of a room air processing unit and an outdoor compression condensation unit.
No matter how their textural association mode changes, its refrigeration principle is consistent: the high pressure-temperature gaseous refrigerant that is formed by compressor compresses during work, become the liquid of high pressure low temperature through condenser radiating tube cooling cooling, again through device for drying and filtering dehumidifying and filtration, flow to expansion valve or kapillary and so on restriction device then, through throttling and the step-down evaporator of flowing through, last low-pressure gaseous refrigerant flows back to compressor again, finishes one and takes turns refrigeration cycle.Cold-producing medium one is met environment under low pressure and is promptly evaporated, and absorbs a large amount of heat energy.The air of driving inner space continues to flow through evaporator by evaporation fan, and the temperature of driving inner space reduces thus.
