Background technology
In mechanics of communication, many communication websites are connected with monitoring network by electronic equipment and control.Environment temperature to electronic equipment requires strict, particularly when annual 24 hours every days continual operations, owing to give out a large amount of heats during various electronic device works, the electronic equipment temperature is raise, in order to guarantee the normal operation of electronic equipment, just must be equipped with air-conditioning equipment, be lowered the temperature; When winter temperature hangs down, must be with the environment heat temperature raising; In spring, time in autumn, then need only aeration-coolingly get final product.According to the difference of temperature in four seasons, the uniform temperature in the holding chamber is to satisfy the temperature requirement of electronic equipment.But existing air-conditioning equipment is generally cold and hot type, promptly can heat when winter, freezes when summer, and when spring and autumn, used season, owing to lack ventilation function, no matter use refrigeration or heat-production functions, all wastes.If the increase ventilation unit, then ventilation equipment take up an area of increases, and unit volume is excessive, needs to build air conditioning equipment room, has also increased investment.In addition, some communication website is uninhabited, requires its air-conditioning equipment in the weather in the four seasons, to press the temperature requirement of electronic equipment under unattended, and the operation that heats up automatically, lowers the temperature, ventilates is to save manpower.
Content of the present invention
The purpose of this invention is to provide a kind of communication machine room special air conditioner unit, it has refrigeration, heats, ventilation function; Its function is complete, and volume is little, and mechanism is simple, need not build the special-purpose machine room of special air conditioner ventilation equipment, and mounting or dismounting are convenient, by robot control system(RCS) is set, then need not special messenger's nurse, saves operating cost.
The objective of the invention is to realize by following technical scheme.
Communication machine room special air conditioner unit of the present invention comprises casing, it is characterized in that:
Described casing has 2 independent plenum chambers, return air chamber, and described plenum chamber has air outlet and communication machine room interlinks; Described return air chamber has fresh wind port and atmosphere interlinks, return air inlet and communication machine room interlinks, condensation exhaust mouth and atmosphere interlink; Having port between described plenum chamber, return air chamber interlinks; On casing, also have the valve plate that can turn round between 2 stations, be used to change gas circuit:
When being positioned at station 1. the time, port and return air inlet are interlinked and making fresh wind port and the condensation exhaust mouth interlinks;
When being positioned at station 2. the time, port and fresh wind port are interlinked and making return air inlet and the condensation exhaust mouth interlinks;
In described casing, refrigerating plant, heating combined equipment are housed;
Refrigerating plant comprises evaporimeter, pressure fan, compressor, condenser fan, condenser, liquid/gas separator, the outlet of compressor links to each other with the inlet of evaporimeter through condenser, the outlet of evaporimeter links to each other with the inlet of compressor through gas-liquid separator, condenser fan is positioned at condenser one side, and pressure fan is positioned at evaporimeter one side;
Evaporimeter, pressure fan all are arranged in plenum chamber; Condenser fan, condenser all are arranged in return air chamber;
Refrigerating plant comprises heater, is positioned at plenum chamber;
