Condenser (2), computer room throttling set (3), gas divide liquid storage device (4), liquid pump (5), computer room evaporator (6), condenser/evaporator (10)
Circuit is constituted with heat pipe condenser (8)；
As outdoor temperature T0≤set temperature T1, room needs heat supply, and air conditioner in machine room needs cooling supply, i.e. room air conditioning system needs
Heating mode is run, air conditioner in machine room needs to carry out liquid phase heat pipe mode, and refrigeration valve (9) is closed at this time, and heat pipe valve (7) is opened, other
Port valve (17) is closed, and computer-room air conditioning system divides liquid storage device (4), liquid pump (5), computer room evaporator (6), condenser/evaporator (10) by gas
Circuit is constituted with heat pipe condenser (8)；Room air conditioning system is by room compressor (11), four-way valve (12), indoor heat exchanger
(13), first throttling device (14), condenser/evaporator (10), second throttling device (15) and outdoor heat exchanger (16) constitute hot water
Circuit.
