Condenser 3, condensation become liquid, and the compressor cycle pipe of Intermediate Heat Exchanger 4 is back flowed back into through compressor electric expansion valve 11
Road.
In the nice and cool variation of spring and autumn transition season outdoor weather, compressor 10 is opened, and all compressors 10 as needed pass through
Frequency conversion provides corresponding cooling capacity；Heat pipe end system 100 uses all outdoor natural cooling sources 210 and mechanical refrigeration source simultaneously
220 be room temperature lowering.Under the operating mode, liquid coolant working medium in every group of 101 ~ 10N of heat pipe evaporator absorbs Indoor Thermal
Amount vaporization becomes steam, and the refrigerant medium of vaporization and the partially liq refrigerant medium not vaporized are fed directly into fluid reservoir 5,
Gas-liquid separation is carried out in fluid reservoir 5；Each group cold source system is advanced on a part of gaseous coolant working medium nature in fluid reservoir 5
Heat pipe condenser 2 discharges heat by outdoor natural cold air, flows back to fluid reservoir 5 by gravity to be condensed into liquid
It is interior；Another part steam in fluid reservoir 5 enters the 4 heat pipe pipeline of each Intermediate Heat Exchanger and compressor cycle of cold source system 200
Refrigerant in pipeline carries out heat exchange, discharges heat, is condensed into liquid and also flows into fluid reservoir 5 by gravity；Fluid reservoir 5
Interior liquid coolant working medium is evaporated through throttle back corresponding heat pipe of 901 ~ 90N of electric expansion valve respectively under the action of circulating pump 8
101 ~ 10N of device；And the liquid refrigerant in the 4 compressor cycle pipeline of each Intermediate Heat Exchanger of cold source system 200 absorbs heat pipe
The heat of pipeline refrigerant release is gasificated as steam, is inhaled into compressor 10, and compressed high pressure gas flows into compressor condensation
Device 3, condensation becomes liquid, and back flows back into 4 compressor cycle pipeline of Intermediate Heat Exchanger through compressor electric expansion valve 11.
