3. a kind of machinery room energy-saving air conditioner device according to claim 1, it is characterised in that：With the heat pipe condenser blower fan
Wind direction is reference direction, and the First Heat Exchanger is placed in before the heat pipe condenser.
4. a kind of machinery room energy-saving air conditioner device according to claim 1, it is characterised in that：Second heat exchanger is partition
Formula heat exchanger or direct contact heat exchanger.
5. a kind of machinery room energy-saving air conditioner device according to claim 1, it is characterised in that：The liquid pump is jet pump, rainbow
Sucking pump or mechanical pump.
6. a kind of machinery room energy-saving air conditioner device according to claim 1, it is characterised in that：Heat pipe cooling major loop and
Refrigeration working medium is sealed inside the pipeline of mechanical refrigeration subloop.
7. a kind of refrigerating method of machinery room energy-saving air conditioner device, it is characterised in that：
At once during Ti-To ＞ M1, heat pipe cooling major loop work is individually opened, mechanical refrigeration subloop is not turned on the work of operation
Pattern 1, wherein Ti are indoor temperature, and To is outdoor temperature, and M1 is that device individually realizes enough temperature controls using outdoor natural cooling source
The stable temperature difference, and M1 ＞ 0；Main triple valve input is connected with heat pipe condenser input under mode of operation 1, in indoor evaporator
Liquid coolant working medium, heat vaporization turns into steam in absorption chamber；Enter heat pipe condenser through the connection of main triple valve and pass through room
Outer natural cold air discharges heat, is flowed into so as to be condensed into liquid in reservoir, the liquid coolant working medium in reservoir is in liquid pump
In the presence of be pumped back to indoor evaporator；Outdoor natural cooling source is used alone by heat pipe condenser in 1 time major loop of mode of operation
For room temperature lowering；
As temperature difference N2 ＜ Ti-To ＜ M1, heat pipe cooling major loop work, while opening the work of mechanical refrigeration subloop operation
Pattern 2, N2 is that heat pipe major loop opens the critical upper limit temperature difference that the operation of mechanical refrigeration source is used alone, and M1 ＞ N2；Working mould
Main triple valve input is connected with heat pipe condenser input under formula 2, and secondary triple valve input is connected with First Heat Exchanger input；Machine
First Heat Exchanger work, the second heat exchanger do not work in tool refrigeration subloop；Outdoor heat pipe condenser by first using by being changed
The natural wind of hot device cooling and work, it can be simultaneously indoor drop using outdoor natural cooling source and mechanical refrigeration source to make heat pipe major loop
Temperature；Mechanical refrigeration subloop according to indoor/outdoor temperature-difference situation and cooling condition with the gap method of operation work, gap length by
Indoor/outdoor temperature-difference size and cooling condition are determined；
When the temperature difference is in N1 ＜ Ti-To ＜ N2 on direction is reduced, device works under pattern 2, and N1 is heat pipe major loop
Open the critical lower limit temperature difference that the operation of mechanical refrigeration source is used alone, and N2 >=N1；
As temperature difference Ti-To ＜ N1, heat pipe cooling major loop work, while opening the mode of operation of mechanical refrigeration subloop operation
3；Now main triple valve input is connected with the input of the second exchanger heat pipe end, secondary triple valve input and the second heat exchanger air conditioner end
Input is connected；The work of the second heat exchanger, heat pipe condenser do not work in heat pipe cooling major loop；Mechanical refrigeration subloop second
Heat exchanger work, First Heat Exchanger do not work；Heat pipe major loop is worked using the cooling of the second heat exchanger, makes heat pipe major loop
It is room temperature lowering that mechanical refrigeration source, which is used alone,；
When the temperature difference is in the case of Ti-To ＜ N1, toward temperature difference augment direction on change and unit continues during in N1 ＜ Ti-To ＜ N2
Under mode of operation 3；The temperature difference is further continued for toward augment direction development, and as temperature difference N2 ＜ Ti-To ＜ M1, unit is transformed under pattern 2.
