Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Fig. 1: structural representation of the present invention.
The specific embodiment
The present invention has disclosed used in communication machine room energy saving integrated air-conditioning, comprises mechanical refrigeration system and indirect heat exchange system, and two cover systems can work alone separately, also can work together.As shown in Figure 1, the both sides of described air-conditioning are respectively arranged with air port, and a crosswind mouth is with respect to indoor server end setting, i.e. air port, inner side.Otherwise be air port, outside.
In described air-conditioning, be provided with for using the air of server end and the dividing plate 9 of isolating as the outside air of low-temperature receiver.
Described mechanical refrigeration system comprises the frequency-changeable compressor 1 of evaporimeter 4, condenser 6 and UNICOM's evaporimeter 4 and condenser 6, and that described indirect heat exchange system comprises is indoor, outdoor heat exchanger and UNICOM is indoor, the circulating pump of outdoor heat exchanger; Described indoor heat exchanger 5 is identical with evaporimeter 4 front face areas, and front and back are against installation, and described outdoor heat exchanger 7 is identical with condenser 6 front face areas, and front and back are against installation.Before and after the above against facies digitales dorsales manus relatively against.
In described air-conditioning, be provided with temperature sensor, described temperature sensor is connected with controller.Described controller can control mechanical refrigeration system and indirect heat exchange system is carried out separately or simultaneously operation.
Below set forth this air conditioner refrigerating principle:
The server out return air of heat passes through evaporimeter 4 and indoor heat exchanger 5, heat is passed to cold-producing medium in evaporimeter 4 and the non freezing solution in indoor heat exchanger 5, cold-producing medium is driven through throttling arrangement and is entered into condenser 6 by frequency-changeable compressor 1, non freezing solution is driven by circulating pump 2, enter outdoor condenser 6, heat is taken away by outdoor cold source air again, between interior gas and outer gas, there is no circulation of air.
Non freezing solution circulation indirect heat exchange system is carried out heat exchange by circulation non freezing solution between interior gas, outer gas side sensible heat exchanger separately.The cold air-conditioning (refrigeration air-conditioner) of driven compressor, be by the refrigerant after the evaporator evaporation heat absorption of interior gas side with after compressor compresses, make its condensing heat release of condenser of gas side outside, thereby realize circularly cooling.Interior gas, outer gas side refer to respectively the both sides of dividing plate 9, with respect to server end be inner side, otherwise be outside.
Below sketch the lower course of work of the present invention:
Generally, this air-conditioning will preferentially be used indirect heat exchange system, when indirect heat exchange system can not meet the demands, will start mechanical refrigeration system.
Native system object is that server intake air is maintained to setting value, after temperature sensor detected temperatures, signal is sent to controller, if controller detects judgement, meets in the situation of indirect heat exchange system service condition, starts indirect heat exchange system; Work as excess Temperature, while only depending on " indirect heat exchange system " cannot maintain setting value, enable " compressor mechanical refrigeration ".
This control is according to the relation of outdoor air inlet temperature and server outlet air temperature, by controller, is automatically implemented: when outdoor temperature is during higher than server air outlet temperature, indirect heat exchange system is not moved, and just moves mechanical refrigeration system; When outdoor temperature is during lower than server air outlet temperature, indirect heat exchange system can be moved, and non freezing solution circulating pump is opened, the suitable reduction of speed of frequency-changeable compressor now, and minimizing machine made cold, realizes energy-conservation; When outdoor temperature is enough low, only indirect heat exchange system just can maintain server inlet temperature in setting value, and mechanical refrigeration can be closed completely, stops compressor operating, thereby realizes maximum energy-conservation.
