Internal gas is cooled down by evaporator 51, and subsequently into interior recycling air channel 45, interior is sent by interior circulating fan 61；
Gas-gas heat exchanger 56 is dividing wall type gas-gas heat exchanger, in heat exchanger outside the circular channels 42 and heat exchanger
Circulation canal 44 is completely isolated by the heat exchanger plate on gas-gas heat exchanger 56, and extraneous gas and internal gas are handed in heat
It changes and heat exchange is only carried out on plate；
One complete condenser cooling gas cyclic process is such：Extraneous gas by gas filtration module 54 filtering and
Gas humidification module 55 enters outer circulation air intake passage 41 after humidifying, and enters back into condenser 52, and heat exchange is carried out with condenser,
Into condenser air-out passage 46, outdoor is then sent out by condenser wind turbine 63.Usually, outdoor air passes through gas humidification mould
Temperature can be reduced after block 55 and becomes low temperature outdoor air, the condenser working temperature of this sample embodiment is lower than outdoor air, energy
So that mechanical refrigeration obtains better refrigeration effect.
As shown in Fig. 2, gas-gas heat exchanger 56 be dividing wall type gas-gas heat exchanger, containing heat exchanger plate,
It is recycled in the interior cycle air inlet 12 of heat exchanger external circulation air inlet 22, heat exchanger outer circulation air outlet 23, heat exchanger, heat exchanger
Air port 13, wherein heat exchanger outside the circular channels 42 and heat exchanger inner cycle channel 44 be by the spaced setting of heat exchanger plate every
Open form into channel, and inlet and outlet is set.Wherein channel of the internal gas inside heat exchanger is logical for cycle in heat exchanger
Road 44, cycle air inlet 12 flows into out of heat exchanger, and air port 13 is recycled out of heat exchanger and is flowed out；Extraneous gas is in heat exchanger
The channel of the inside is heat exchanger outside the circular channels 42, is flowed into from heat exchanger external circulation air inlet 22, from heat exchanger outer circulation outlet air
Mouth 23 flows out.
For example, the interior circulation return air temperature for running certain data center of this indirect evaporation precision air conditioner is 35 DEG C, interior needs
The wind pushing temperature to be controlled is 23 DEG C.During summer, when 37 DEG C of extraneous gas temperature, relative humidity 50%（Wet-bulb temperature is at this time
28℃）, interior circulation return air can not be cooled to expected 23 DEG C just with indirect evaporating-cooling at this time, need compressor operating
Carry out secondary cooling.Specific work process is：When the extraneous gas enters the external circulation conduit of indirect evaporation precision air conditioner, lead to
Relative humidity is close to 100% after crossing gas humidification module humidification, and gas temperature is close to 28 DEG C, after gas-gas heat exchanger
Extraneous gas temperature is upgraded to 34.3 DEG C.In being recycled in inside, 35 DEG C of internal gas, by cold after gas-gas heat exchanger
But it is 28.7 DEG C, then 23 DEG C is cooled to by evaporator, passes through the opposite of gas-gas heat exchanger acquisition during this
Refrigerating capacity is approximately（35℃-28.7℃）/（35℃-23℃）=52.5%, i.e. it is total to assume responsibility for this data center for indirect evaporating-cooling
The 52.5% of cooling load, and the refrigerating capacity that mechanical refrigeration needs provide is only 47.5%, frequency-changeable compressor is under such operating mode, energy
Effect is much higher at full capacity frequently.In addition, when 30 DEG C of extraneous gas temperature, during relative humidity 40%, wet-bulb temperature is 20 DEG C at this time,
It is warm by the humidification relative humidity of gas humidification module close to 100% when the extraneous gas passes through indirect evaporation precision air conditioner
Degree is 33.5 DEG C by extraneous gas temperature after gas-gas heat exchanger close to 20 DEG C.35 DEG C of internal gas, by gas-
Temperature after gas heat-exchanger can reach 21.5 DEG C, i.e., disclosure satisfy that internally by indirect evaporating-cooling under this situation
The cooling demand of portion's gas, compressor can not work.
The present embodiment has developed together with two kinds of type of cooling series combinations of mechanical refrigeration and indirect evaporating-cooling a
Completely new equipment can cool down to server outlet air using indirect evaporating-cooling in spring, autumn, winter, summer first with
Indirect evaporating-cooling carries out preliminary cooling and then mechanical refrigeration is recycled to be cooled down twice not up to 23 DEG C expected air,
It is energy-saving to achieve the purpose that.It can accomplish North of Yangtze River most area at home, the annual compressor start time does not surpass
3 months are spent, greatly improves year round cooling efficiency.Because being low load operation when summer frequency-changeable compressor starts simultaneously, and
And indirect evaporation condenser is used, mechanical refrigeration efficiency can also be substantially improved.
