Step S32 when the indoor temperature in the communication base station is lower than atmospheric temperature outside the base station, can only lean on the air-conditioning unit to come to the cooling of the electronic equipment in the base station, so need to adopt mechanical compression refrigeration to reduce temperature in the base station.Therefore need open first vent passages, first vent passages is opened in natural cooling air valve disc sheet rotation, closes second vent passages and the 3rd ventilation passage simultaneously.
Step S33 starts condensation fan, unit condenser, circulating fan, unit evaporimeter, refrigeration compressor work, carries out mechanical compression refrigeration.
Step S34, air in the communication base station is under the effect of unit circulating fan, enter unit by return air inlet, interior first vent passages of unit this moment is unimpeded, second vent passages and the 3rd ventilation passage are cut off by natural cooling air valve disc sheet, therefore can only in unit, flow along first vent passages by the air that enters in the base station, filter through air cleaner, indoor by unit evaporimeter refrigeration back by air outlet entry communication base station.
Step S35, when the indoor temperature in the communication base station is higher than atmospheric temperature outside the base station, it is indoor that can be incorporated into communication base station with outdoor cold air this moment fully, replace with the communication base station room air, thus reduction communication base station indoor temperature.Therefore, first vent passages is closed in natural cooling air valve disc sheet rotation, opens second vent passages and the 3rd ventilation passage simultaneously.
Step S36, circulating fan work stops the operation of mechanical refrigeration parts such as condensation fan, unit condenser, unit evaporimeter, refrigeration compressor simultaneously.
Step S37, interior first vent passages of unit this moment is cut off by natural cooling air valve disc sheet, and second vent passages and the 3rd ventilation passage are unimpeded.Outdoor new cold air is under the effect of unit circulating fan, enter in the unit by unit front panel air intake barrier, enter into the refrigerant compression unit room, vertical lifting is to nature cooling air-valve then, pass through air cleaner by cooling naturally downwards behind the air-valve, and through pressure fan and unit evaporimeter by in the empty inlet chamber of air-supply.The benefit of doing like this is: in rainy season, outdoor air contains a large amount of water droplets can be separated at the passage of this rising, again by behind air cleaner and the evaporimeter, air in the inlet chamber can compare drying comparatively speaking, and the humid air that water droplet can not occur containing is directly sent into indoor and influenced the indoor electric subset.Owing to have in the outdoor air inlet chamber that constantly is recycled the blower fan suction, communication base station is indoor will to produce malleation, therefore the hot-air on indoor upper strata enters unit and process nature cooling air-valve and unit front panel air exhausting grille row to outdoor by the unit return air inlet under the effect of malleation.Replace the indoor air of heat by the outdoor new cold air of continuous entry communication base station,, also embodied the function of unit energy-saving run simultaneously to greatest extent to finish the inside of base station refrigeration cool-down.
As can be seen from the above embodiments, the utility model embodiment realizes the purpose of air refrigeration cycle in the communication base station by adopting different vent passages, and be lower than in outdoor temperature under the situation of indoor temperature, power consumption such as close compressor parts, only depending on circulating fan to introduce outdoor new cold air to have realized energy-conservation effect to the cooling of communication base station indoor temperature.In addition, this unit has the characteristics of compact conformation, profile unanimity, has dwindled unit volume, and is easy to a large amount of productions, has reduced production cost.
The above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
